Mediapolulla - Kasvatustieteellistä ja teknisen alan osaamista yhdistämässä : Opiskelijoiden yhteistyö ja oppiminen tieto- ja viestintätekniikkaprojektissa

The study concentrated on interdisciplinary teamwork of students in Helsinki University Department of Education and Helsinki University of Technology. Students worked in small interdisciplinary groups (n 12) to plan and teach in an information- and communication technology (ICT) club in elementary schools. The focus of the study was co-operation in the student groups and students learning experiences. Theoretical background of the study consists of theories of collaboration and socially shared cognition. Study was an qualitative case study and the data was collected with individual focus interviews and learning diaries. The data was categorised and the connections between categories were analysed with a table. Shared cognition appeared as a form of distribution of tasks and in the actual processes of shared expertise. The tasks were shared according to students expertise. Processes of shared expertise were joint knowledge building, integration of interests, awareness and exploitation of others expertise and allowing freedom for others to use their expertise. Additionally expression of ones own views and setting an example to others were one sided sharing of expertise. Students of technology were responsible of technical issues and the responsibility sphere of educational science students was more fragmented. For instance they concentrated in taking children s abilities into consideration. The sphere of shared cognition included also the need for tutoring and learning from others. Usually students did not directly learn from representative of other discipline, instead the learning for instance of social skills happened indirectly. Learning was fostered if learning was set as a goal and prevented if the differences in expertise were too minor. Sharing of cognition was prevented if co-operation was too problematic. Co-operation was usually successful. Good planning, good person chemistry and appreciation of expertise of others promoted success. Problems caused by different backgrounds were usually slight. Successful interaction was complementary and equal. Groups were usually able to circumvent problems in communication and use of justification in discussion promoted co-operation. When comparing the groups in the scope of the study, two were found to be notably opposed and the other groups located between these extreme cases, but the elements of success prevailed. Learning experiences concentrated on social skills, project management, school world and ICT. Essential was achieved field experience and observation of ones own capabilities. In organisation of student interdisciplinary co-operation is important to ensure sufficient differences in expertise and guide students to gain complementary interaction and appropriate setting of goals. Interdisciplinary field project prepared students to face the demands of

"Valehtelu ei auta, mutta kaikkea ei kannata kertoa." : Kertomatta jättäminen parisuhteen vuorovaikutuskontekstissa

Topic avoidance in romantic relationships has not been researched before in Finnish speech communication research, and this study was expected to increase the understanding of a phenomenon that acquires relatively dramatic attributes in everyday conversation. The aim of this study was to describe topic avoidance based on what was told in the interviews, and to describe the beliefs concerning functional or dysfunctional relational communication that can be interpreted from the interviewees' speech when they talk about topic avoidance. The theoretical reference frame of this study consists of the Communication Privacy Management Theory, relational dialectics, and earlier, mostly American research on topic avoidance. Ten Finnish people aged 22-31, who all had previous experience on one or more marital or common-law relationships were interviewed for this study. Additional material for the study was gathered from the interviewees by using the role playing method to describe interactional events where something essential is left unsaid in the context of romantic relationship. The following values were attributed to functional communication in romantic relationships: openness, equality, honesty, trust and positivity. The dialectical nature of the phenomenon being researched is evident in the way that along with openness, the interviewees talked about excessive openness that should occasionally be avoided in the context of relational communication by leaving things unsaid. Topic avoidance was seen both as a conscious strategic communication for managing privacy, and as an uncontrollable force of nature that at its worst destroys the relationship. When topic avoidance is seen as strategic communication, the choice concerning what is left unsaid is made by weighing the following dimensions asgainst each other: risks/ benefits (for self, relationship), protects/ does not protect (self, partner, relationship), burdens/ does not burden (self, partner, relationship), honesty/ dishonesty, responsibility lies with self/ responsibility does not lie with self. Topic avoidance was acceptable if it was used in order to preserve the relationship, as opposed to gaining power in the relationship or causing insecurity for the partner. The acceptability of topic avoidance varied according to whether it differed from lying or not. When the interviewees talk about topic avoidance, their speech can be interpreted to mean that in spite of uncontrollability, communicative choices can be made in relational communication and that skills concerning communication in romantic relationships can be learned.

Oppimispäiväkirja kliinisen laboratoriotyön opiskelijan ohjauksessa

Tutkimuksen tarkoituksena oli selvittää, voidaanko oppimispäiväkirjaa käyttää kliinisen laboratoriotyönkäytännön opiskelijaohjaustoiminnassa oppimisen apuvälineenä. Tutkimuksessa lähdetään liikkeelle teoreettisten tietojen ja käytännön taitojen yhdistämisen tärkeydestä. Tutkimuksessa tarkastellaan oppimista kokemuksellisen oppimisen näkökulmasta ja kuinka se auttaa laboratoriohoitajaopiskelijaa laatimaan mieleensä käytännön opiskelun skeemoja ja kuinka ne toteutuvat heidän käytännön taitojen karttuessa. Tutkimukseen osallistui vuoden 1997 aikana HYKS:n laboratoriossa käytännön opiskelujaksolla olleita laboratoriohoitajaopiskelijoita. Heitä pyydettiin laatimaan käytännön opiskeluohjauksestaan oppimispäiväkirja. Laatiminen oli vapaaehtoista. Oppimispäiväkirjamerkinnöissä kiinnitettiin huomiota, kuinka he oppivatkäytännön taitoja ja kuinka heidän oppimisprosessinsa kehittyy heidän itsearvioimana. Jotkut laboratoriohoitajaopiskelijat halusivat laatia useammalta käytännön opiskelujaksoltaan oppimispäiväkirjan, joten oppimispäiväkirjoja (n=9) on enemmän kuin tutkimukseen osallistuneita laboratoriohoitajaopiskelijoita (n=6). Tutkimuksen keskeisenä menetelmenä on kvalitatiivinen analyysimenetelmä. Sisällönanalyysiä ja luokittelumenetelmää käyttäen pyrittiin löytämään käsityksiä ja niistä edelleen käsitysluokkia. Käsitysluokat tukivat sitä käsitystä, että oppimispäiväkirjaa voidaan käyttää apuvälineenä laboratoriohoitajaopiskelijoiden oppimisen tukena kliinisen laboratoriotyön käytännön opiskelussa. Tutkimustulokset osoittavat, että oppimispäiväkirjat toimivat laboratoriohoitajaopiskelijoiden tiedon jäsentäjinä käytännön opiskelujakson aikana. Oppimispäiväkirjan avulla laboratoriohoitajaopiskelija selventää itselleen kokonaiskuvaa kliinisen laboratoriotyön prosessista. Oppimispäiväkirjan avulla voidaan kerrata jo opittuja asioita ja voidaan suorittaa itsearviointia ja reflektoida oppimiskokemuksien antamia hyötyjä ja haittoja. Oppimispäiväkirjoissa tuli esille se, että laboratoriohoitajaopiskelijat selkiyttivät oppimiaan asioita ja omiaajatuksiaan suhteessa työelämään silloin, kun he kirjoittivat oppimispäiväkirjojaan. Oppimispäiväkirjojen kirjoittaminen koko käytännön opiskelujakson aikana tuki myös muiden käytännön opiskelujaksojen tavoitteiden asettamista. Oppimispäiväkirja on ammatillisen kehittymisen kannalta hyvä kertauksen, kriittisen ajattelun ja reflektoinnin väline. Oppimispäiväkirjoissa tuli kuvauksia itsearvioinnista, laboratoriohoitajaopiskelijat asettivat itsensä alttiiksi omalle arvioinnilleen hyvinkin helposti ja esittivät kriittisiä kannanottoja työskentelytapojen kehittämiseksi, huolellisuuden, tarkkuuden ja vastuuntunnon vahvistamiseksi. Tärkeimmät lähteet taustateorian kannalta olivat Engeströmin, Hätösen, Lonka & al, Leino-Kilven, Rauste-von Wrightin ja Silven & Kinnunen & Keskisen teokset. Tutkimusmenetelmän kannalta tärkeimmät lähteet olivat Hirsjärvi & Remes & Sajavaara, Lincoln & Cubanja Varton teokset.

Widening Perspectives of Teacher Education : Studies on theory-practice relationship, reflection, research and professional development

This dissertation examined the research-based teacher education at the University of Helsinki from different theoretical and practical perspectives. Five studies focused on these perspectives separately as well as overlappingly. Study I focused on the reflection process of graduating teacher students. The data consisted of essays the students wrote as their last assignment before graduating, where their assignment was to examine their development as researchers during their MA thesis research process. The results indicated that the teacher students had analysed their own development thoroughly during the process and that they had reflected on theoretical as well as practical educational matters. The results also pointed out that, in the students’ opinion, personally conducted research is a significant learning process. -- Study II investigated teacher students’ workplace learning and the integration of theory and practice in teacher education. The students’ interviews focused on their learning of teacher’s work prior to education. The interviewees’ responses concerning their ‘surviving’ in teaching prior to teacher education were categorized into three categories: learning through experiences, school as a teacher learning environment, and case-specific learning. The survey part of the study focused on integration of theory and practice within the education process. The results showed that the students who worked while they studied took advantage of the studies and applied them to work. They set more demanding teaching goals and reflected on their work more theoretically. -- Study III examined practical aspects of the teacher students’ MA thesis research as well as the integration of theory and practice in teacher education. The participants were surveyed using a web-based survey which dealt with the participants’ teacher education experiences. According to the results, most of the students had chosen a practical topic for their MA thesis, one arising from their work environment, and most had chosen a research topic that would develop their own teaching. The results showed that the integration of theory and practice had taken place in much of the course work, but most obviously in the practicum periods, and also in the courses concerning the school subjects. The majority felt that the education had in some way been successful with regards to integration. -- Study IV explored the idea of considering teacher students’ MA thesis research as professional development. Twenty-three teachers were interviewed on the subject of their experiences of conducting research about their own work as teachers. The results of the interviews showed that the reasons for choosing the MA thesis research topic were multiple: practical, theoretical, personal, professional reasons, as well as outside effect. The objectives of the MA thesis research, besides graduating, were actual projects, developing the ability to work as teachers, conducting significant research, and sharing knowledge of the topic. The results indicated that an MA thesis can function as a tool for professional development, for example in finding ways for adjusting teaching, increasing interaction skills, gaining knowledge or improving reflection on theory and/or practice, strengthening self-confidence as a teacher, increasing researching skills or academic writing skills, as well as becoming critical and being able to read scientific and academic literature. -- Study V analysed teachers’ views of the impact of practitioner research. According to the results, the interviewees considered the benefits of practitioner research to be many, affecting teachers, pupils, parents, the working community, and the wider society. Most of the teachers indicated that they intended to continue to conduct research in the future. The results also showed that teachers often reflected personally and collectively, and viewed this as important. -- These five studies point out that MA thesis research is and can be a useful tool for increasing reflection doing with personal and professional development, as well as integrating theory and practice. The studies suggest that more advantage could be taken of the MA thesis research project. More integration of working and studying could and should be made possible for teacher students. This could be done in various ways within teacher education, but the MA thesis should be seen as a pedagogical possibility.

Kotitaloustaidon ulottuvuuksia : Analyysi kotitaloustaidosta eksistentialistis-hermeneuttisen fenomenologian valossa

DOMESTIC SKILLS AS THE ART OF EVERYDAY LIFE. An inquiry about domestic skills as a way of being-in-the-world in the light of existentialist-hermeneutics phenomenology. This study focuses on analyzing domestic skills in a phenomenological manner. The description phenomenological emerges from the interpretation process, which originates from the ontological question of domestic skills. The ontological question of how domestic skills are directs one s phenomenological gaze to the experiencing of domestic skills, rather than merely viewing their action or technical aspects. Along with the ontological question, the axiological question of what the meaning of domestic skills is drives the analysis. This study is both theoretical and philosophical. Phenomenology is the guiding philosophy, theory and methodology of the inquiry. Existentialist-hermeneutics is the emphasis which most appropriately describes the phenomenological attitude adopted within the analysis. Martin Heidegger s philosophy of being and Maurice Merleau-Ponty s philosophy of the lived body essentially form the theoretical base for the inquiry. The analysis reveals domestic skills within a core of Care and the Other. Care and the Other are anchored both in Heidegger s analysis of Dasein and in Merleau-Ponty s analysis of the reversible being-in-the-world. The social nature of being and the action-oriented intentionality of the lived body are embodied in Care and the Other. This ontological base of domestic skills enables us to see the extensions that inhabit in it. These extensions are redoing, emotional experiencing, adapting and emancipating. The analysis connects ability and action, which is why domestic skills and household activity must be seen as a united whole. This united whole is not the matter of the two components of the phenomenon, but is rather the matter of domestic skills as a way of being-in-the-world. Domestic skills are a channel for the phenomenon Home Economics to manifest in our lives. This is the gaze that presents domestic skills as to be like the poetry of everyday life. The main result of the study is the elucidation of the ontology of domestic skills and the naming of its extensions. This growth of philosophical understanding makes it possible to strengthen the science of home economics.

Noviisiopettajana peruskoulussa : Aloittelevien opettajien autenttisia kokemuksia ensimmäisestä opettajavuodesta

As a Novice Teacher at Comprehensive School: The authentic experiences of the beginning teachers during their first year of teaching The aim of this study is to explicate the novice year of teaching in the light of teachers´ authentic experiences. The subject of this investigation is the teachers´ subjective world of experience during their first academic year of teaching and the sharing of these experiences in collaborative consulting meetings. The themes discussed in the meetings were introduced into the collaborative group by the novice teachers themselves, and the progress of discussion was con-trolled by them. The research data was gathered in a consultative working group where the way a novice teacher starts to interpret, analyze and identify his/her own complex and dynamic teaching situations was observed. The research data gathered in this way illuminates novice teachers´ world of experience and mental picture as well as the unconscious sides of school life. In a theoretical frame of reference, the work of a teacher is identified, according to systemic scientific thought, as a dynamic triangle in which the basic elements are the personality of the teacher, the role of the teacher and the school as an organization. These basic elements form a whole within which the teacher works. The dynamics of this triangle in a teacher’s work are brought to light through the study of the phenomena of groups and group dynamics since a teacher works either as a member of a group (working community), as a leader of a group (teaching situations) or in a network (parent – teacher cooperation). Therefore, tension and force are always present in teaching work. The main research problem was to explain how a novice teacher experiences his/her first working year as a teacher. The participants (n=5) were teaching at five different comprehensive schools in the city of Helsinki. This was their first long-term post as a teacher. The research data consists of seven collaborative consulting meetings, as well as recordings and transcripts of the meetings. A classificatory framework was developed for data analysis which enabled a sys-tematic qualitative content analysis based on theory and material. In addition to the consulting meetings, the teachers were interviewed at the beginning and at the end of the process of collecting the research material. The interviews were used to interpret the meanings of the content analysis based on raw data. The findings show that there is a gap between teacher education and the reality of school life, which causes difficulties for a novice teacher during his/her first teaching year. The gap is rather a global educational problem than a national one, and therefore it is independent of cultural factors. Novice teachers desire a well-structured theory of teacher education and a clear programme where the themes and content delve deeper and deeper into the subject matter during the study years. According to the novice teachers, teacher education frequently consists of sporadic and unconnected study and class situations. An individual content weakness of teacher education is the lack of insufficient initiation into evaluation processes. The novice teachers suggest that a student must be provided good-quality and competent guidance during the study years and during his or her induction. There should be a well-organized, structured and systematic induction program for novice teachers. The induction program should be overseen by an organization so that the requirements of a qualified induction can be met. The findings show that the novice teachers find the first year of teaching at comprehensive school emotionally loaded. The teachers experienced teaching as difficult work and found the workload heavy. Nevertheless, they enjoyed their job because, as they said, there were more pleasant than unpleasant things in their school day. Their main feeling at school was the joy of success in teaching. The novice teachers felt satisfaction with their pupils. The teachers experienced the more serious feelings of anger and disgust when serious violence took place. The most difficult situations arose from teaching pupils who had mental health problems. The toughest thing in the teacher´s work was teaching groups that are too heterogeneous. The most awkward problems in group dynamics happened when new immigrants, who spoke only their own languages, were integrated into the groups in the middle of the school year. Teachers wanted to help children who needed special help with learning but restated at the same time that the groups being taught shouldn’t be too heterogeneous. The teachers wished for help from school assistants so that they could personally concentrate more on teaching. Not all the parents took care of their children according to the comprehensive school law. The teachers found it hard to build a confidential relationship between home and school. In this study, novice teachers found it hard to join the teaching staff at school. Some of the teachers on staff were very strong and impulsive, reacting loudly and emotionally. These teachers provoked disagreement, conflicts, power struggles and competition among the other teachers. Although the novice teachers of the study were all qualified teachers, three of them were not interested in a permanent teaching job. For these teachers teaching at a primary school was just a project, a short period in their working life. They will remain in the teaching profession as long as they are learning new things and enjoying their teaching job. This study is an independent part of the research project on Interplay – Connecting Academic Teacher Education and Work, undertaken by the Department of Applied Sciences of Education at the University of Helsinki. Key words: novice teacher, emotions, groups and group dynamics, authority, co-operation between home and school, teacher community, leadership at school, induction, consulting

Visuaalis-spatiaalisten työmuistivalmiuksien yhteys (esi)matemaattisiin taitoihin ja merkitys osana matemaattisilta taidoiltaan heikkojen lasten ja nuorten kognitiivista profiilia

Tämän itsenäisistä osatutkimuksista koostuvan tutkimussarjan tavoitteena oli pyrkiä täydentämään kuvaa matemaattisilta taidoiltaan heikkojen lasten ja nuorten tiedonkäsittelyvalmiuksista selvittämällä, ovatko visuaalis-spatiaaliset työmuistivalmiudet yhteydessä matemaattiseen suoriutumiseen. Teoreettinen viitekehys rakentui Baddeleyn (1986, 1997) kolmikomponenttimallin ympärille. Työmuistikäsitys oli kuitenkin esikuvaansa laajempi sisällyttäen visuaalis-spatiaaliseen työmuistiin Cornoldin ja Vecchin (2003) termein sekä passiiviset varastotoiminnot että aktiiviset prosessointitoiminnot. Yhteyksiä työmuistin ja matemaattisten taitojen välillä tarkasteltiin viiden eri osatutkimuksen avulla. Kaksi ensimmäistä keskittyivät alle kouluikäisten lukukäsitteen hallinnan ja visuaalis-spatiaalisten työmuistivalmiuksen tutkimiseen ja kolme jälkimmäistä peruskoulun yhdeksäsluokkalaisten matemaattisten taitojen ja visuaalis-spatiaalisten työmuistitaitojen välisten yhteyksien selvittämiseen. Tutkimussarjan avulla pyrittiin selvittämään, ovatko visuaalis-spatiaaliset työmuistivalmiudet yhteydessä matemaattiseen suoriutumiseen sekä esi- että yläkouluiässä (osatutkimukset I, II, III, IV, V), onko yhteys spesifi rajoittuen tiettyjen visuaalis-spatiaalisten valmiuksien ja matemaattisen suoriutumisen välille vai onko se yleinen koskien matemaattisia taitoja ja koko visuaalis-spatiaalista työmuistia (osatutkimukset I, II, III, IV, V) tai työmuistia laajemmin (osatutkimukset II, III) sekä onko yhteys työmuistispesifi vai selitettävissä älykkyyden kaltaisella yleisellä päättelykapasiteetilla (osatutkimukset I, II, IV). Tutkimussarjan tulokset osoittavat, että kyky säilyttää ja käsitellä hetkellisesti visuaalis-spatiaalista informaatiota on yhteydessä matemaattiseen suoriutumiseen eikä yhteyttä voida selittää yksinomaan joustavalla älykkyydellä. Suoriutuminen visuaalis-spatiaalista työmuistia mittaavissa tehtävissä on yhteydessä sekä alle kouluikäisten esimatemaattisten taitojen hallintaan että peruskoulun yhdeksäsluokkalaisten matematiikan taitoihin. Matemaattisilta taidoiltaan heikkojen lasten ja nuorten visuaalis-spatiaalisten työmuistiresurssien heikkoudet vaikuttavat kuitenkin olevan sangen spesifejä rajoittuen tietyntyyppisissä muistitehtävissä vaadittaviin valmiuksiin; kaikissa visuaalis-spatiaalisen työmuistin valmiuksia mittaavissa tehtävissä suoriutuminen ei ole yhteydessä matemaattisiin taitoihin. Työmuistivalmiuksissa ilmenevät erot sekä alle kouluikäisten että kouluikäisten matemaattisilta taidoiltaan heikkojen ja normaalisuoriutujien välillä näyttävät olevan kuitenkin jossain määrin yhteydessä kielellisiin taitoihin viitaten vaikeuksien tietynlaiseen kasautumiseen; niillä matemaattisesti heikoilla, joilla on myös kielellisiä vaikeuksia, on keskimäärin laajemmat työmuistiheikkoudet. Osalla matematiikassa heikosti suoriutuvista on näin ollen selvästi keskimääräistä heikommat visuaalis-spatiaaliset työmuistivalmiudet, ja tämä heikkous saattaa olla yksi mahdollinen syy tai vaikeuksia lisäävä tekijä heikon matemaattisen suoriutumisen taustalla. Visuaalis-spatiaalisen työmuistin heikkous merkitsee konkreettisesti vähemmän mentaalista prosessointitilaa, joka rajoittaa oppimista ja suoritustilanteita. Tiedonkäsittelyvalmiuksien heikkous liittyy nimenomaan oppimisnopeuteen, ei asioiden opittavuuteen sinänsä. Mikäli oppimisympäristö ottaa huomioon valmiuksien rajallisuuden, työmuistiheikkoudet eivät todennäköisesti estä asioiden oppimista sinänsä.

Yksi historia monimutkaistuvasssa maailmassa : Historian olemus ja historian suuret kertomukset luokanopettajaopiskelijoiden historiatietoisuudessa

One history in a multicomplex world The quintessence of history and grand historical narratives in the historical consciousness of class teacher students The study analyses the conception of history amongst class teacher students at the University of Helsinki. It also explores the expectations about the future that the students have on the basis of their views on history. The conceptions of the students are analysed against the background of the notion of one history which has been part of Western thought in the modern era and which is at the centre of the theoretical framework of this study. The Enlightenment project and the erosion of the role of the Church paved the way for the notion that history is an linear narrative of the progress of humankind and in which, implicitly, the Western countries are endowed with a special role as the vanguards of progress. In recent times these assumptions have been criticised by postmodernists and proponents of New History. The material of the study consists of interviews of twenty-two 19 26 years old class teacher students at the University of Helsinki. The topics in the interviews were the developments of the past and the future trajectories. The students conceived history as a field of knowledge that provides a unifying view on the world and helps to make today s world intelligible. Finnish history and global history were invested with features of a grand narrative of progress. In global history, progress and development were seen as characteristic of the Western world primarily. The students regarded the post-war Finnish history as a qualified success story in that they deplored the erosion of collectivist values and the rise of selfishness in recent decades. History was not conceived as a process of progress that would self-evidently continue in the future, but rather more as a field of contingency and cyclical change.The students regarded the increasing predominance of the market forces over democratically elected agencies, the antagonism between the West and the other parts of the world, and environmental risks as the major threats. Notwithstanding this general.pessimism about the future, the students had a very positive view of their own personal prospects. Keywords: historical consciouness, one history, future expectations

Anthraquinones from the Fungus Dermocybe sanguinea as Textile Dyes

This study is based on the multidiciplinary approach of using natural colorants as textile dyes. The author was interested in both the historical and traditional aspects of natural dyeing as well as the modern industrial applications of the pure natural compounds. In the study, the anthraquinone compounds were isolated as aglycones from the ectomycorrhizal fungus Dermocybe sanguinea. The endogenous beta-glucosidase of the fungus was used to catalyse the hydrolysis of the O-glycosyl linkage in emodin- and dermocybin-1-beta-D-glucopyranosides. The method, in which 10.45 kg of fresh fungi was starting material, yielded two fractions: 56.0 g of Fraction 1 (94% of the total amount of pigment,) consisting almost exclusively of the main pigments emodin and dermocybin, and 3.3 g of Fraction 2 (6%) consisting mainly of the anthraquinone carboxylic acids. The anthraquinone compounds in Fractions 1 and 2 were separated by one- and two-dimensional thin-layer-chromatography (TLC) using silica plates. 1D TLC showed that neither an acidic nor a basic solvent system alone separated completely all the anthraquinones isolated from D. sanguinea, in spite of the variation of the rations of the solvent components in the systems. Thus, a new 2D TLC technique was developed, applying n-pentanol-pyridine-methanol (6:4:3, v/v/v) and toluene-ethyl acetate-ethanol-formic acid (10:8:1:2, v/v/v/v) as eluents. Fifteen different anthraquinone derivatives were completely separated from one another. Emodin, physcion, endocrocin, dermolutein, dermorubin, 5-chlorodermorubin, emodin-1-beta-D-glucopyranoside, dermocybin-1-beta-D-glucopyranoside and dermocybin, and five new compounds, not earlier identified in D. sanguinea, 7-chloroemodin, 5,7-dichloroemodin, 5,7-dichloroendocrocin, 4-hydroxyaustrocorticone and austrocorticone, were separated and identified on the basis of their Rf-values, UV/Vis spectra and mass spectra. One substance remained unidentified, because of its very low concentration. The anthraquinones in Fractions 1 and 2 were preparatively separeted by liquid-liquid partition, with isopropylmethyl ketone and aqueous phosphate buffer as the solvent system. Advantage was taken of the principle of stepwise pH-gradient elution. The multiple liquid-liquid partition (MLLP) offered an excellent method for the preparative separation of compounds, which contain acidic groups such as the phenolic OH and COOH groups. Due to their strong aggregation properties, these compounds are, without derivatization, very difficult to separate on a preparative scale by chromatographic methods. By the MLLP method remarkable separations were achieved for the components in each mixture. Emodin and dermocybin were both obtained from Fraction 1 in a purity of at least 99%. Pure emodin and dermocybin were applied as mordant dyes to wool and polyamide and as disperse dyes to polyester and polyamide, using the high temperature (HT) technique. A mixture of dermorubin and 5-chlorodermorubin was applied as an acid dye to wool. In these experiments, synthetic dyes were used as references. Experiments were also performed using water extract of the air-dried fungi as dye liquor for wool and silk. The main colouring compounds in the crude water extract were emodin and dermocybin, which indicated that the O-glycosyl linkages in emodin- and dermocybin-1-beta-D-glucopyranosides were broken by the beta-glucosidase enzyme. Apparently, the hydrolysis occurred during the drying of the fungi and during the soaking of the dried fruit bodies overnight when preparing the dyebath. The colour of each dyed material was investigated in terms of the CIELAB L*, a* and b* values, and the colour fastness to light, washing and rubbing was tested according to the ISO standards. In the mordant dyeing experiments, emodin dyed wool and polyamide yellow and red, depending on the pH of the dyebath. Dermocybin gave purple and violet colours. The colour fastness of the mordant-dyed fabrics varied from good to moderate. The fastness properties of the natural anthraquinone carboxylic acids on wool were good, indicating the strength of the ionic bonds between the COO- groups of the dyes and the NH3+ groups of the fibres. In the disperse dyeing experiments, emodin dyed polyester bright yellow and dermocybin bright reddish-orange, and the fabrics showed excellent colour fastness. In contrast, emodin and dermocybin successfully dyed polyamide brownish-orange and wine-red, respectively, but with only moderate fastness. In industrial dyeing processes, natural anthraquinone aglycone mixtures dyed wool and silk well even at low concentrations of mordants, i.e. with 10% of the weight of the fibre (owf) of KAl(SO4)2 and 1 or 0.5% owf of other mordants. This study showed that purified natural anthraquinone compounds can produce bright hues with good colour-fastness properties in different textile materials. Natural anthraquinones have a significant potential for new dyeing techniques and will provide useful alternatives to synthetic dyes.

Is a Majority Enough? Psychological Well-being and Its Relation to Academic and Prosocial Motivation, Self-regulation and Achievement at school

This cross-sectional study analyzed psychological well-being at school using the Self-Determination theory as a theoretical frame-work. The study explored basic psychological needs fulfillment (BPNS), academic (SRQ-A), prosocial self-regulation (SRQ-P) and motivation, and their relationship with achievement in general, special and selective education (N=786, 444 boys, 345 girls, mean age 12 yrs 8 mths). Motivation starts behavior which becomes guided by self-regulation. The perceived locus of control (PLOC) affects how self-determined this behavior will be; in other words, to what extent it is autonomously regulated. In order learn and thus to be able to accept external goals, a student has to feel emotionally safe and have sufficient ego-flexibility—all of which builds on satisfied psychological needs. In this study those conditions were explored. In addition to traditional methods Self-organizing maps (SOM), was used in order to cluster the students according to their well-being, self-regulation, motivation and achievement scores. The main impacts of this research were: a presentation of the theory based alternative of studying psychological well-being at school and usage of both the variable and person-oriented approach. In this Finnish sample the results showed that the majority of students felt well, but the well-being varied by group. Overall about for 11–15% the basic needs were deprived depending on the educational group. Age and educational group were the most effective factors; gender was important in relation to prosocial identified behavior. Although the person-oriented SOM-approach, was in a large extent confirming what was no-ticed by using comparison of the variables: the SEN groups had lower levels of basic needs fulfillment and less autonomous self-regulation, interesting deviations of that rule appeared. Some of the SEL- and GEN-group members ended up in the more unfavorable SOM-clusters, and not all SEN-group members belonged to the poorest clusters (although not to the best either). This evidence refines the well-being and self-regulation picture, and may re-direct intervention plans, and turn our focus also on students who might otherwise remain unnoticed. On the other hand, these results imply simultaneously that in special education groups the average is not the whole truth. On the basis of theoretical and empirical considerations an intervention model was sug-gested. The aim of the model was to shift amotivation or external motivation in a more intrinsic direction. According to the theoretical and empirical evidence this can be achieved first by studying the self-concept a student has, and then trying to affect both inner and environmental factors—including a consideration of the basic psychological needs.

Self-Concept and School Achievement of Pupils with Cleft Lip, Cleft Palate or Both : A longitudinal study

The goal of this research was to survey the self-concept and school achievement of pupils with cleft lip, cleft palate or both from juvenile age to adolescence. Longitudinal researches of self-concept and school achievement among pupils with cleft lip, cleft palate or both are uncommon. This research was the first longitudinal research ever conducted in Finland among this population. This research can be considered to be a special educational study because of the target group involved. Self-concept consists of the person s entire personality. Personality is biological and deterministic. Self-concept includes concepts, attitudes and feelings that the person has about him or her qualities, abilities and relations to the environment. The individual associates experiences to this personality with earlier observations through the social interaction. The individual will have the consciousness of the person s existence and action. The target group in this study consisted of Finnish children with clefts, who were comprised of four different age groups. The questionnaire was sent to all subjects (N1 = 419) both times. A total of 74 % of children returned the questionnaire in 1988 (N2=305). 48 % of children returned the questionnaire in 1993 (N3=203). 42% of children returned the questionnaire both times (N4=175) . These 175 children formed the research subjects. The survey was conducted in 1988, and again in 1993. In 1988, the pupils surveyed were 9 to 12 years of age, while in 1993 they were between 14 and 17 years old. The data was collected through the use of a questionnaire, which consisted of common questions and a personality inventory test that was developed for Finnish students by professor Maija-Liisa Rauste-von Wright. Quantitative analysis methods were used to examine the structure of self-concept and school achievement. Structures found in this research were observed in relation to disorder, gender and maturation. According to these results, structures of self-concepts and school achievement are in fact stable. Basic self-concept elements are seen to be formed at an early age. The developmental aspects of self-concept following puberty are observed as the stability of self-concept and as the forming of a general self. The level of school achievement is stable, but the structure of school achievement changes. From these results, it is possible to state that the gender of the child has a statistical significance regarding self-concept and school achievement. However, the experienced disorder does not have statistical significance as regards to self-concept and school achievement. Results of self-concept support the research of self-concept conducted earlier in Finland.

Rakkaat vanhemmat? : Perheen merkityksestä erityisluokan oppilaalle

The aim of this study was to find out the meaning family has for a pupil who studies in a special class, or how important family is for the pupil s emotional life, the development of his self-confidence, freetime activities, attitudes on school, plans for further studies and his general social development. The theoretical base of this study was formed by social scientists' theories on postmodern family, which is due to urbanization and urban life style, and theories on family pluralism, the powerful effects that changes in family life have on pupils in special education, the weak self-confidence and low sosioeconomic background among those pupils and the effects of family's sosioeconomic status on pupil's willingness to get education or the theory on the accumulation of education. Study problems were set in the direction determined by these theories and in order to study the accurateness of the theories. The method used in the study was theme interview, which is sometimes also called half-structured interview. The material for the study was collected in October 1998 in a special school in Helsinki. The material contains answers given by pupils in theme interviews and background information about pupils' families, which where collected from the pupils' parents by mail. Content analysis was used to analyze the material. The study showed that it is very important to pupils' attitudes on school and their self-confidence that their families are entire and that the families give them support. The children, whose parents are interested in school education and discuss a lot about things, seem to have positive attitudes on school and good self-confidence, too. The parental support also has an effect on how the pupils spend their free time and on their hobbies, too. Obviously the families have quite an important meaning for pupils in special class, but if the families don t support them, the consequence is problems particularly for the development of self-confidence. The theory on the low sosioeconomic background among students in special education gets support from this study, but nothing can be said about it's effect on further studies. On account of the results it can be suggested that special schools must arrange occasions where the pupils' parents are clearly informed about the important meaning of their support for the pupils studies and the development of the pupils' self-confidence. The most important sources for the theoretical background were the books written by Jallinoja, Kivinenand Rinne, Moberg, Scanzoni and P. Takala. The most important sources for the method were the books written by Hirsjärvi and Hurme and Pietilä.

Teologian opiskelijoiden henkilökohtaiset projektit ja opintomenestys

Motivation and personal goals play an important role in the ways in which people direct their behavior. Personal goals are closely connected with well-being but they also relate to how people perform in different achievement domains. Many studies show that evaluating study-related goals as important, easy to attain and non stressful, predict better academic achievements than evaluating them as non attainable and stressful (Salmela-Aro & Nurmi, 1997b). The aim of this study was to describe motivational factors among theology students. They form an interesting group in terms of exploring connections between motivation, spiritual goals and academic achievements. The average duration of graduation at the Faculty of Theology is among the highest at the University of Helsinki. On the other hand, it may be assumed that many theology students have spiritual goals which affect their studies. A special focus was paid on the different evaluations of study-related personal projects and how they are related to academic achievement. A methodology of personal projects (Little, 1983) was used to study what kind of personal goals theology students are engaged in during their studies. In the first part of the questionnaire the subjects (N=133) were asked to describe important personal projects. They were given four numbered lines for their written responses. In the second part the subjects were asked to rate projects concerning their studies according to 13 dimensions using a 7-point Likert-scale. Three subgroups were formed on a K-Means Cluster Analysis on the basis of evaluations of the study-related projects. The groups were named committed, self-fulfillers and non-committed according to their evaluations of their study related projects. Academic achievements among the different groups varied substantially. After two years of studying the students who were in the committed group had completed on an average twenty study credits more than those who were in the non-committed group. Self-fulfillers placed in the middle of the three groups. Committed and self-fulfiller students also reported higher levels of intrinsic reasons for striving towards study-related goals. The results indicate that goals reported at the beginning of studies predicted academic achievement later on. The results also showed that different evaluations of goals have long lasting connections to progress in studying. Implications for student well-being and how these results can be utilized for student counseling are discussed.

Lähiympäristö nepalilaisessa arjessa - oppilaiden ja opettajien käsityksiä omista vaikutusmahdollisuuksistaan

Aims. Sustainable development has become the most important theme in the development co-operation in the 21st century. Sustainable development is pursued by environmental education among other things. This research rose from the discussion about the meaning of environmental education in developing countries and especially the effect it might have in the environment and society. Nepal and one of its rural private schools was selected as a research object. The themes and questions of the research are: 1. Conceptions of the immediate environment of students and teachers: What does immediate environment mean according to the students and teachers? 2. Students most important acts in the environment: What kind of effect do the students think they can have on the environment in their everyday life? 3. Teachers opinions, experiences and methods in environmental education: What do teachers think should be taught to the students in environmental education? What are the teachers actually teaching? What kind of methods are the teachers using while teaching environmental education? Researching the conceptions of immediate environment and acts in the environment gives information about the students and teachers relation with the nature in their everyday life and the baseline from which environmental education will be implemented from. Teachers opinions, experiences and methods in environmental education provide information on the current implementation of the environmental education. Methods. Ethnography was selected as a research method. Before collecting the actual data, a pre-study was conducted. The aim of the pre-study was to specify the research themes and practice the cross-cultural interview as a research method. The actual data was collected in the last week of January 2010 in Dhangadhi, Nepal. The data included twenty-two drawings and captions from the students and one group interview with the teachers. The data was analyzed with brief quantitative analysis and full analysis was done with a qualitative method called content analysis. Results and conclusions. Teachers and student s conceptions of immediate environment differ from each other. Students saw the immediate environment from the scientific approach while the teachers thought it was more social conception. The interface was found in their own personal environment. This interface is a good baseline for environmental education. The most important acts in the environment for the students were protection towards the environment. The students saw their possibilities to have an influence in the environment through the school. A connection between the school and acting in the environment was evident. In the teachers opinions and experiences of environmental education, environmental problems and the importance of teaching attitudes and values were found. No logic thematic entities were discovered but the teachers did use different kinds of methods in their teaching. Achieving the international aims for environmental education was very challenging in the research school because of the teachers lack of information and skills to teach the subject. The context where the school works was also challenging.

In this research the technical functionality, quality and demands made on endurance runners` running suits in winter conditions were studied. The aim was also to find out how smart clothing and wearable technology are adopted in endurance runners` practise. Referring to previous studies the subject was approached in the theoretical part by studying the profile of endurance running, sports wear and the technology to wear as well as the smart clothing from the point of view of endurance running. The basis of subject was the interest of smart materials and the connection between technical structures and functionality. In the science of handicrafts smart clothing is rarely researched which made it even more interesting for the author. This research was carried out by the principles of the usability research. Usability means the suitability of product to its intended meaning. In the research both quantitative and qualitative methods were used. Researched persons were active competitive long-distance runners and also the long-distance runners doing it as a hobby, 35 male and 12 female runners. User information was gathered by the internet forms which mainly was based on the multiple choices but also included few open questions. Gathered information was considered by using both quantitative and content analysing methods. The functional long-distance running practice suit in winter conditions consisted of layered look which considered the possibilities of functional and smart materials. The Practise suit was humid transformable, easy care and light also comfortable to wear. These suits were hoped to be more functional than the current ones. The future running suit was described to not to feel or notice during running. It will not be too tight or sweltering. The functional abilities of clothing materials were believed to be developed further more. Even if the new technical materials are adopted for the running suits the technology to wear is not even though half of the researched runners used pulse indicators. The runners hoped the technology to wear to change more invisible and easier to use. Some of the runners wished the technology to wear to be integrated straight to the clothes which would reduce the number of devices carried with while running. The rare use of Polar Adidas AdiStar Fusion practise system and some other similar systems for endurance running was surprising. According to the results the smart clothing would not make a big brake through in the near future. In the point of view of the researched persons developing of clothing materials was a good and necessary thing, but integrating too much technology to the hobby smears the main purpose of sports and focuses wrongly on the metres and others minors .
