Latvialaiset opiskelijat suomen nominintaivutuksen oppijoina

Tutkielman pääpaino on suomen kielen morfologiassa. Tutkielmassa tarkastellaan latvialaisten suomen kielen opiskelijoiden nominintaivutuksen oppimista ja siihen liittyviä ongelmia. Työssä pohditaan myös suomen nominintaivutuksen vaikeutta sekä tuotosten että oman arvion pohjalta. Tulosten analyysissa tarkastellaan, miten hyvin informantit osaavat muodostaa eri nominityyppien perusmuodoista yksikön genetiivin ja monikon partitiivin sijamuodot. Analyysin tärkeänä osana on virheellisten tuotosten analyysi. Tutkimuksella selvitetään, mitkä ovat vaikeimpia nominityyppejä ja ovatko tietyt virheet tyypillisiä tietyille nominityypeille tai tietyn sijan muodostukselle. Tutkimuksessa selvitetään myös eri astevaihtelujen vaikeutta. Tutkielman tärkeimpänä lähteenä on Martinin väitöskirja (1995). Taivutustestin tuloksia verrataan Martinin taivutustestin tuloksiin. Aineistona ovat keväällä 2008 Latvian yliopistossa pidetyn taivutustestin tulokset. Informantteina olivat latvialaiset toisen ja kolmannen vuosikurssin opiskelijat, jotka kaikki opiskelevat suomen kieltä pääaineena suomalais-ugrilaisten kielten kandidaattiohjelmassa. Informantteja oli yhteensä 24. Ryhmä oli oppimistaustaltaan hyvin homogeeninen. Työssä osoitetaan, että latvialaiset opiskelijat hallitsevat suomen nominintaivutuksen toisella ja kolmannella vuosikurssilla jo kohtuullisen hyvin. Parhaiten hallitaan kaksitavuisten u-päätteisten nominien, nen- ja in-päätteisten nominien, astevaihteluttomien e:ee-nominien sekä Us:Ukse-nominien taivutus. Huonoiten hallitaan tOn-päätteisten nominien taivutus. Usein taivutusvaikeus on kytköksessä tiettyyn sijaan: osa nomineista on helpompi taivuttaa monikon partitiivissa, osa yksikön genetiivissä. Virheisiin johtavat syyt ovat yleensä nominin sijoittaminen väärään taivutustyyppiin, vartalonmuodostusongelmat sekä astevaihtelun ja taivutussääntöjen soveltamisen ongelmat. Tutkimustulokset ovat samansuuntaisia Martinin tulosten kanssa. Sanojen tuttuus ei kuitenkaan vaikuttanut yhtä vahvasti taivutustuloksiin – tekosanat hallittiin lähes yhtä hyvin kuin todelliset sanat. Sen sijaan nominin leksikaalinen tuttuus on avainasemassa informanttien omassa taivutusvaikeuden arvioinnissa. Semanttisesti tai taivutustyypiltä tutut sanat luokiteltiin useammin helpoiksi. Taivutustestini tulokset osoittavat enemmän hajontaa morfofonologisen kompleksisuuden edellyttämän järjestyksen osalta Martinin tuloksiin nähden. Taivutusvaikeuteen morfofonologisen kompleksisuuden, nominityypin käyttöyleisyyden sekä lekseemin tuttuuden lisäksi vaikuttavat myös oppimiskonteksti ja nominiin kytkeytyvä ongelmapotentiaali. Informanttien taivutusstrategioista yleisin on taivutussääntöjen käyttö.

Learning challenges of NGOs in development : Co-operation of Finnish NGOs in Morogoro, Tanzania

Non-governmental organisations (NGOs) have gained an important role in development co-operation during the last two decades. The development funding channelled through NGOs has increased and the number of NGOs engaged in development activities, both North and South, has been growing. Supporting NGOs has been seen as one way to strengthen civil society in the South and to provide potential for enhancing more effective development than the state, and to exercise participatory development and partnership in their North-South relationships. This study focuses on learning in the co-operation practices of small Finnish NGOs in Morogoro, Tanzania. Drawing on the cultural-historical activity theory and the theory of expansive learning, in this study I understand learning as a qualitative change in the actual co-operation practices. The qualitative change, for its part, emerges out of attempts to deal with the contradictions in the present activity. I use the concept of developmental contradiction in exploring the co-operation of the small Finnish NGOs with their Tanzanian counterparts. Developmental contradiction connects learning to actual practice and its historical development. By history, in this study I refer to multiple developmental trajectories, such as trajectories of individual participants, organisations, co-operation practices and the institutional system in which the NGO-development co-operation is embedded. In the empirical chapters I explore the co-operation both in the development co-operation projects and in micro-level interaction between partners taking place within the projects. I analyse the perceptions of the Finnish participants about the different developmental trajectories, the tensions, inclusions and exclusions in the evolving object of co-operation in one project, the construction of power relations in project meetings in three projects, and the collision of explicated partnership with the emerging practice of trusteeship in one project. On the basis of the empirical analyses I elaborate four developmental contradictions and learning challenges for the co-operation. The developmental contradictions include: 1) implementing a ready-made Finnish project idea vs. taking the current activities of Tanzanian NGO as a starting point; 2) gaining experiences and cultural interaction vs. access to outside funding; 3) promoting the official tools of development co-operation in training vs. use of tools and procedures taken from the prior activities of both partners in actual practice; and 4) asymmetric relations between the partners vs. rhetoric of equal partnership. Consequently, on the basis of developmental contradictions four learning challenges are suggested: a shift from legitimation of Finnish ideas to negotiation, transcending the separate objects and finding a partly joint object, developing locally shared tools for the co-operation, and identification and reflection of the power relations in the practice of co-operation.

Lionhearts of the Playworld : An ethnographic case study of the development of agency in play pedagogy

This is an ethnographic case study of the creation and emergence of a playworld – a pedagogical approach aimed at promoting children’s development and learning in early education settings through the use of play and drama. The data was collected in a Finnish experimental mixed-age elementary school classroom in the school year 2003-2004. In the playworld students and teachers explore different social and cultural phenomena through taking on the roles of characters from a story or a piece of literature and acting inside the frames of an improvised plot. The thesis takes under scrutiny the notion of agency in education. It produces theoretically grounded empirical knowledge of the ways in which children struggle to become recognized and agentive actors in early education settings and how their agency develops in their interaction with adults. The study builds on the activity theoretical and sociocultural tradition and develops a methodological framework called video-based narrative interaction analysis for studying student agency as developing over time but manifesting through the situational material and discursive local interactions. The research questions are: 1. What are the children’s ways of enacting their agency in the playworld? 2. How do the children’s agentive actions change and develop over the spring? 3. What are the potentials and challenges of the playworld for promoting student agency? 4. How do the teachers and the children deal with the contradiction between control and agency in the playworld? The study consists of a summary part and four empirical articles which each have a particular viewpoint. Articles I and II deal with individual students’ paths to agency. In Article I the focus is on the role of resistance and questioning in enabling important spaces for agency. Article II takes a critical gender perspective and analyzes how two girls struggled towards recognition in the playworld. It also illuminates the role of imagination in developing a sense of agency. Article III examines how the open-ended and improvisational nature of the playworld interaction provided experiences and a sense of ‘shared agency’ for the students and teachers in the class. Article IV turns the focus on the teachers and analyzes how their role actions in the playworld helped the children to enact agency. It also discusses the challenges that the teachers faced in this work and asks what makes the playworld activity sustainable in the class. The summary part provides a critical literature review on the concept of agency and argues that the inherently contradictory nature of the phenomenon of agency has not been sufficiently theorized. The summary part also locates the playworld intervention in a historical frame by discussing the changing conceptions of adulthood and childhood in the West. By focusing on the changing role of play and art in both adults’ and children’s contemporary lives, the thesis opens up an important but often neglected perspective on the problem of promoting student agency in education. The results illustrate how engaging in a collectively imagined and dramatized pretend play space together with the children enabled the teachers to momentarily put aside their “knower” positions in the classroom. The fictive roles and the narrative plot helped them to create a necessary incompleteness and open-endedness in the activity that stimulated the children’s initiatives. This meant that the children too could momentarily step out of their traditional classroom positions as pupils and initiate action to further the collective play. Engaging in this kind of unconventional activity and taking up and enacting agency was, however, very challenging for the participating children and teachers. It often contradicted the need to sustain control and order in the classroom. The study concludes that play- and drama-based pedagogies offer a unique but undeveloped potential for developing educational spaces that help teachers and children deal with the often contradictory requirements of schooling.

Nuorten kokema yksinäisyys ja sen yhteys tulevaisuusorientaatioon

The aim of this study was to examine 1) how much and how adolescents experience loneliness, 2) how they orientate to the future, 3) are loneliness experiences and future attitudes associated with self-esteem and 4) are loneliness experiences associated with future orientation. The data (n=172) was collected in September 2003 and it consisted of 9th grade students living in countryside and city. The research was quantitative questionnaire study and it was statistically analysed. So far the problem of loneliness has not been noticed enough. People experience loneliness when there is discrepancy between actual and desired levels of interpersonal contact. In adolescence loneliness is quite common because young people go through the crises of human relationships and identity. In adolescence the meaning of friends and fellows increases and the relationship with parents changes. Future orientation becomes meaningful in adolescence because young people have to make realistic choices concerning their future life. In this study almost every adolescent had someone to be with and talk to. However 19% of adolescents experienced loneliness. Lonely adolescents experienced lack of friendships and fellowships. Lonely adolescents also felt that they left outside of others and that they were alone. Boys experienced more often lack of friendships and fellowships than girls. Girls experienced that they left more often outside and that they were more often alone than boys. Adolescents living in city experienced a little more loneliness experiences than adolescents living in countryside. Lonely adolescents had also difficulties to make social relationships and they experienced loneliness also related with parents. Lonely adolescents had also weak self-esteem. Adolescents orientated to the future mainly positively. The most important future target was health and the least important target was the universal peace and problems solving of the world. Adolescents believed that they affect to their future mainly by themselves and they planed their future about 5-10 years ahead. For adolescents it was important to have education and work to the future. In the future it was also important to have a lifelong companion and own family. For most of the young people it was also important to keep up social relationships and realize him/herself. Adolescents thought high standard of living and money also quite important things in the future. Girls preferred different future targets more important than boys. For the boys only money and high standard of living were more important than for girls. 18% of adolescents had pessimistic attitude to the future. For pessimistic adolescents many future targets were less important than for the adolescents having affirmative or optimistic attitude for the future. Adolescents who had pessimistic attitude to the future had also weak self-esteem. For the lonely adolescents it was not so important 1) to keep up social relationships and realize themselves in the future. Lonely adolescents did not prefer 2) lifelong companion and own family as important as other young people. Also 3) others acceptance and appreciation were not so important for lonely adolescents. 4) Travelling was also more insignificant for lonely than for others. Lonely adolescents future attitudes were quite pessimistic. Parent related loneliness explained future targets insignificance and pessimistic attitude for the future the most. The experience of loneliness seems to be associated with future orientation in many cases. That s why it is important to pay attention to adolescents loneliness experiences. Loneliness is real and serious problem which threats health. Thus we need to examine further loneliness in adolescence and as a result of that it is possible to develop and use interventions to help lonely adolescents to orientate positively to their future.

Tiedonhakustrategiat World Wide Webissä

Tutkimuksen tarkoituksena on selvittää, millaisia tiedonhakustrategioita tiedonhakijatkäyttävät etsiessään tietoa Internetistä. Käyttäjät luokitellaan kolmeen ryhmään tiedonhakustrategiansa mukaan. Haku-suuntautuneet käyttäjät käyttävät enimmäkseen hakukoneita, niin koko Internetin kattavia kuin sivustojen sisäisiäkin. Linkkisuuntautuneet taas joko tietävät tai arvaavat kohdesivuston osoitteen tai käyttävät laajoja hierarkkisia hakemistoja tiedon löytämiseen. He navigoivat mielummin sivustollakin linkkejä käyttäen eivätkä yleensä käytä hakutoimintoa. Eriytyneet käyttäjät eivät säännönmukaisesti suosi kumpaakaan tapaa, vaan valitsevat strategian tehtävän mukaan. Tietoa kerättiin kahdella tavalla: WWW-sivulla olleella kyselylomakkeella ja tiedonhakutestillä, jossa käyttäjille annettiin suoritettavaksi erilaisia tiedonhakutehtäviä. Tiedonhakutehtävät lajiteltiin kolmeen ryhmään sen mukaan, mitä strategiaa ne suosivat: hakustrategiaa suosivat, linkkistrategiaa suosivat ja neutraalit tehtävät. Tutkimusongelmana oli selvittää, kuinka tehtävän tyyppi ja ATK- ja Internet-kokemus vaikuttavat tiedonhakustrategian valintaan. Kävi ilmi, ettei käyttäjien suuntautuneisuus tiettyyn strategiaan vaikuta tiedonhakustrategian valintaan, vaan ainoastaan tehtävän tyyppi oli merkitsevä tekijä. Aikaisemman tutkimustiedon valossa kokeenet suosivat haku-suuntautunutta strategiaa. Tässä tutkimuksessa havaittiin, että kokemus lisäsi molempien strategioiden käyttöä yhtäläisesti, mutta tämä ilmiö oli havaittavissa ainoastaan kysely-lomakkeen pohjalta, ei testeissä. Molempien tiedonhakustrategioiden käyttö lisääntyy kokemuksen myötä, mutta suhteelliset osuudet pysyvät samoina. Syyksi sille, että kokeneet eivät suosineet hakustrategiaa, esitetään sitä, että tehtävät olivat liian helppoja, jolloin kokemus ei pääse auttamaan. Oleellisia eroja suoritusajoissa tai hakustrategian vaihdon tiheydessä ei havaittu suhteessa kokemukseen, ainoastaan suhteessa tehtävän tyyppiin.Tämäkin selitettiin toisentyyppisten tehtävien helppoudella. Tutkimuksessa pohditaan lisäksi asiantuntijuuden syntyä tiedonhakukontekstissa sekä esitetään metatietohypoteesi, jonka mukaan tiedonhakustrategian valintaan vaikuttaa tärkeänä tekijänä käyttäjän metatieto hakupalveluista. Metatietoon kuuluu tieto siitä, mitä hakukoneita on saatavilla, mitä tietoa verkosta kannattaa hakea, millä yrityksillä ja yhteisöillä on sisältörikkaat sivut jne, ja minkä tyyppistä tietoa yleensä on saatavilla. Kaikenkaikkiaan strategian valintaan esitetään taustalle kolmen tason tiedon vaikutusta: 1) oma asiantuntemus haettavasta alasta, 2) metatieto Internetin tiedonhakupalveluista sekä 3) tekninen tieto siitä, kuinka hakukoneet toimivat.

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.

Aika hyvä rehtoriksi : Selviääkö koulun johtamisesta hengissä?

The aim of this study was to describe school leadership on a practical level. By observing the daily behaviour of a principal minute by minute, the study tried to answer the following questions: how did the principals use their time, did they have time to develop their school after participating in the daily life of the school, and how did the previously studied challenges of modern leadership show in their practical work? Five principals in different areas of Helsinki were observed – two women and three men. The principals were chosen at random from three educational conferences. The main hypothesis of this research was that the work of the principal consists of solving daily problems and routines concerning the pupils, teachers and other interest groups and writing all kinds of bureaucratic reports. This means that the school and its principal do not have enough resources to give to a visionary development of teaching and learning – in other words pedagogical leading – even though every principal has the best knowledge about his or her own school’s status quo and the needs for development revealed by this status quo. The research material was gathered by applying the Peer-Assisted Leadership method. The researcher shadowed each principal for four days for three hours at a time. After each shadowing period, any unclear situations were clarified with a short interview. After all the shadowing periods, the principals participated in a semi-structured interview that covered the themes emerging from the shadowing material. In addition to this, the principals evaluated their own leading with a self-assessment questionnaire. The results gathered from the shadowing material showed that the actions of the principals were focused on bureaucratic work. The principals spent most of their time in the office (more than 50%). In the office they were sitting mainly by the computer. They also spent a significant mount of time in the office meeting teachers and occasional visitors. The time spent building networks was relatively short, although the principals considered it as an important domain of leadership according to their interviews. After the classification of the shadowing material, the activities of the principals were divided according to certain factors affecting them. The underlying factors were quality management, daily life management, strategic thinking and emotional intelligence. Through these factors the research showed that coping with the daily life of the school took about 40% of the principals’ time. Activities connected with emotional intelligence could be observed over 30% and activities which required strategic thinking were observed over 20% of the time. The activities which according to the criteria of the research consisted of quality management took only 8% of the principals’ time. This result was congruent with previous studies showing that the work of school leaders is focused on something other than developing the quality of teaching and learning. Keywords: distributed leadership, building community, network building, interaction, emotional intelligence, strategy, quality management

"Pintaa syvemmälle" : Eettinen pohdinta opettajan voimavarana luokanopettajan ja erityisopettajan silmin

The purpose of this study is to determine what class teachers and special teachers emphasise in ethical consideration, in which situations they find that ethical difficulties arise and how they would overcome them. In additions, the study aims to describe the effects of ethical con-sideration on the teachers` work. The theoretical backround is based on theories concerning the ethics of the teacher and the literature associated with education and teaching. The empirical study was based on data obtained through questionnaires and interviews. The questionnaires were posted to 470 randomly-selected class teachers and special teachers; 298 of them (63%) completed and returned the questionnaire, and 19 teachers were inter-viewed. The results of the questionnaires and the interviews were examined crosswise with a mixed-methods procedure. The questionnaires were analysed by factor analysis. Those items which rose above the av-erage served as the foundation for the analysis. The questionnaires also included open ques-tions. These questions and the interviews were analysed with a content analysis method. Some principles of this method were combined with the results of the questionnaires to in-crease mutual understanding. In this study, the ethical consideration of the teachers was divided in to four notable parts: 1) moral obligations, 2) respect for the teaching stuff, 3) the demand for responsibility, and 4) dependence on the situation. These items were also notable both in situations that were ethi-cally difficult for teachers and in their solutions to these situations. It became evident that these situations were very common in everyday work and resulted from the character of the teachers´ work. This study showed that the teacher meets the pupils as a group and that the teacher must examine according to the circumstances the truth, individuality, special ar-rangements and co-operation between the school and the parents. The teachers` continuous lack of time limited the ethical consideration. It emerged that the teachers consider their work very multi-faceted and that the sense of obligation, power and responsibility was inevitably received emphasis. The consciousness of authority and the responsibilities associated with it seemed, however, to strengthen this ac-tion. The study showed that the teachers, especially the young female ones, long for more solidarity. Significantly, such experience does not eliminate the importance of ethical consid-eration; on the contrary, it deepens it. According to the results, creating conditions and cir-cumstances for the teachers that open co-operation is inevitable, and easy interaction will in-evitably be possible in the future. There was not observed any differences in ethical consideration between class teachers and special teachers. Therefore, the integration of the pupils to general teaching cannot be consid-ered questionable. Teachers´ answers suggested that ethical consideration improved the tolerance of stress, increased self-confidence and courage as well as belief in the future. The teachers considered ethical consideration important and encouraging for it increased justice and empathy in the teachers´ work.

Dialogisuus ja kohtaaminen : Tutkimus kristillisten koulujen toimintakulttuurista kasvatussuhteen näkökulmasta

The main focus of this research was to describe the educational purpose of Christian schools within their operation culture. The Christian schools founded in Finland can be seen as part of a greater movement in Europe. In this research the dialogue and encounter in the educational scheme of Finnish Christian schools were examined by asking three research questions: 1. What is the nature of the dialogue in education in Finnish Christian schools? 2. How do the teachers describe themselves as educators? 3. What are the special characteristics in the operation culture of a Christian school? The educational relationship was regarded as fundamental and in the background reflected the absolute value of each student. Communication skills were viewed as essential in the building of relationships, which also included emotion communication skills as a broader view. The teachers expressed their comprehension of the meaning of the dialogue in the building of a relationship with practical examples. Students learned to understand one another's experiences by discussion and listening to one another. The values that created a connection were mutual appreciation, honesty, taking the other one into account, and the ability for empathy. Caring was regarded as a relationship between people, as well as a genuine mutual encounter, in which all parties would listen to one another and be heard by others. The respondents thought that individual attention and time were the keys to reaching well-being and an encounter. Students' commitment to the community was supported by mutual agreements, identifying with the common world, and encounters. The appearance of Christian love agape was named as the basis for an educational relationship. The answers emphasised shared everyday life at school. According to the teachers, the willingness for personal growth enabled encounters, although growth as such was often regarded as difficult. Cognitive emphasising and emotional experiencing from a dynamic perspective, were the means by which students' ethical understanding was comprehended. The teachers named three key factors to create a confidential relationship: a respectful attitude, courage, and genuineness. Within the school operational environment, a sense of community was emphasised, in which each student was taken into account individually. The active role of parents was an essential part of the school culture. The administration of the schools appeared committed. The additional pressure in school work came from efforts to ensure the official status of the school, as well as the large amount of administrative work involved in a private school. According to the research data, there was no evidence to support any elitism that is often associated with private schools.

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.

Koulu muistoissa : Tulevat opettajat muistelevat kouluaikaansa

Tutkielmassa tarkasteltiin opettajaksi opiskelevien koulumuistoja ja niissä esiintyviä positiivisia ja negatiivisia kokemuksia koulusta, oppimisesta ja opettajasta. Tutkimusmetodiksi valittiin koulumuistoista kirjoittaminen tarkoituksena helpottaa sekä kokemusten tuomista tietoisuuteen että niiden myöhempää käsittelyä kirjallisina dokumentteina. Opiskelijoita pyydettiin kirjoittamaan erään yhteisen luennon alussa parhaasta ja huonoimmasta koulumuistostaan. Tutkimuksen tarkoituksena oli kartoittaa opiskelijoiden muistoja koulusta. Tutkimuksen avulla pyrittiin myös osittain selittämään kokemuksien yhteyksiä toisiinsa. Tutkimusongelmina esitettiin seuraavat kysymykset: minkälaisia muistoja koulusta tulee ensimmäisenä mieleen, miten opettajan merkitys näkyy kyseisissä muistoissa, minkälaisen kuvan opiskelijoiden muistot antavat koulusta, ja miten muistoissa kuvatut koulukokemukset ovat mahdollisesti vaikuttaneet opiskelijoiden myöhempään elämään. Tutkimusjoukko koostui 101:stä Helsingin yliopiston opettajankoulutuslaitoksen ensimmäisen vuoden opiskelijasta, lastentarhanopettajan, luokanopettajan, kotitalousopettajan sekä käsityöopettajan koulutuslinjoilta. Koulumuistot sijoittuivat pääasiassa peruskouluaikaan, sillä opiskelijoista suurin osa oli alle 25-vuotiaita. Opiskelijoiden kirjoittamat muistot analysoitiin ja tulkittiin kvalitatiivisen tutkimusotteen mukaisesti. Analysointiluokkien muodostamiseen saatiin malli kahdesta aikaisemmasta tutkimuksesta. Ruotsalaisen Pérez Prieton koulukokemustutkimus ja amerikkalaisen Johnson Rothenbergin tutkimus opiskelijoiden koulumuistoista toimivat tämän tutkimuksen tärkeimpinä lähteinä teoriataustassa. Tutkimustulosten mukaan yli puolet opiskelijoiden koulumuistoista liittyi opettajaan. Opettajanvaikutus oli merkittävin negatiivisten muistojen kohdalla ja suurin osa maininnoista esiintyi nöyryytyskokemusten yhteydessä. Nöyryyttävinä koettiin tilanteet, joissa opettaja oli rankaissut julkisesti tai toiminut oppilaan oikeuksia vastaan. Positiivisissa muistoissa opettaja esiintyi noin viidesosassa maininnoista, pääasiassa menestymiskokemusten ja haastavuuden yhteydessä. Menestymiskokemukset,joihin liittyi yleensä itsensä toteuttamisen mahdollisuus, muodostivat suurimman parhaiden koulumuistojen luokan. Myös kaverit ja koulun ilmapiiri olivat merkittäviä tekijöitä niin hyvien kuin huonojenkin kokemusten kohdalla. Muita analysointiluokkia edellisten lisäksi olivat epäonnistuminen, turhautuminen, arvostelu, koulunvaihto ja rehtori. Teoreettisessa viitekehyksessä selvitettiin kokemuksen käsitettä ja sen soveltuvuutta tutkimuksen kohteeksi. Tärkeitä lähteitä tutkimuksen kokemuksellisen luonteen kannalta olivat Deweyn ja Jarvisin teokset, joissa käsiteltiin kokemuksen merkitystä kasvatukselle ja oppimiselle sekä reflektion vaikutusta kokemuksen merkittävyydelle. Lisäksi tarkasteltiin tutkimuksia koulukokemusten merkittävyydestä opettajaopiskelijoille ja opettajan merkityksestä oppilaalle tärkeänä aikuisena.

Purpose: The study focuses on the question, how to advance textile cultural interpretation skills in museum. The theme was actual, because there have been many workshops in different kind of museums, which have raised textile into important role of their museum pedagogy. The knowing of nature of textile materials was highlighted in former studies as the most crucial thing in craft. That is reason for choosing textile to study. The theoretical approach of study was particularized to the meanings which have been given to craft during recent ten years. Furthermore the composition of textile culture and transmitting textile cultural heritage were examined throug the theory. The finnish museum as a place for learning, as well as the contens of museum pedagogy, were analyzed. The fundamental approach to study was cultural research and art education. Methods: The methodological approach was theory-based theme interview. Before interviewing informants the charting was made by using literature, interviews and observation, to find out the most important themes within subject. Specialists were interviewed personally and results were sent to them by e-mail for further comments. There were 8 informants and they were chosen with intentional sampling from different kind of museums, from teacher education and among craft teachers. Research material was analyzed with content analysis by using deductive reasoning. Conclusions: The study revealed that there are three strategies in advancing textile cultural interpretation. The most remarkable strategies are 1) making acquaintance of materials and working with them, 2) getting exiting events with posibilities to use one s whole body and 3) getting textile cultural knowledge by using for example discovery - style learning. In practice those strategies were mixed, which also was considered advisable. Another conclusion the study revealed, is the desirable, acceptable attitude not only to the craft with creative, free beginning but also to the craft made like its model in museum. Learning from model can be felt as a very moving experience, like a journey in time. The side result of the study was the importance of collaboration of museums and schools in advancing textile cultural interpretation skills as well as significance of using internet in collaboration and relations.

Kummimaatilatoiminta opettajien ja maatilojen sekä innovaatiotutkimuksen näkökulmista

Tutkimuksen tarkoituksena on selvittää Finfood - Suomen Ruokatieto ry:n alullepanemassa kummimaatilatoiminnassa mukana olleiden opettajien ja maatilojen käsityksiä ja kokemuksia toiminnasta sekä tarkastella kummimaatilatoimintaa innovaationa. Kummimaatilatoiminta liittyy Finfoodin internetissä julkaisemaan oppimateriaaliin suomalaisen ruoan tiestä. Kummimaatilatoiminnan tavoitteena on, että mahdollisimman monella peruskoululuokalla olisi oma kummimaatila, missä luokka voisi vierailla vuosittain, joka säilyisi luokalla mahdollisimman pitkään ja jonka kanssa luokka suunnittelee oman yhteistyönsä. Kummimaatilatoiminnan avulla pyritään omakohtaisten kokemusten ja elämysten kautta lisäämään nuorten tietoa maaseudun elämästä. Tutkimuksen tausta -osassa tarkastellaan koulun ja yhteiskunnan muiden tahojen yhteistyötä, esitellään tutkimuksia koulun ja teollisuusyritysten yhteistyöstä sekä koulun ja maatalouden yhteistyöhön liittyvää materiaalia. Lisäksi tarkastellaan innovaatiota ja innovaation diffuusiota. Koska kummimaatilatoiminta on uusi toimintamuoto, jossa toisena osapuolena on koulu, tutkimuksessa käsitellään myös kasvatuksen muutoksia (educational change). Tutkimusta käsitellään tapaus- ja toimintatutkimuksena. Tutkimusaineistona ovat kummimaatilatoiminnan alkuvaiheessa syksyllä 1997 mukaan lähteneiden seitsemän opettajan ja kuuden maatilan teemahaastattelut. Tutkimuksessa on haastateltu myös Finfoodin edustajaa. Aineisto kerättiin kevään ja syksyn 1998 aikana. Innovaatiotarkastelun pohjana ovat lisäksi tutkijan omat kokemukset toiminnasta sekä erilaiset kokoukset ja keskustelut. Opettajien ja maatilojen kokemuksista selvitettiin heidän toiminnan aloittamiseen johtaneita motiivejaan, toiminnalle asettamiaan tavoitteita, toiminnassa havaitsemiaan ongelmia sekä käsityksiä toiminnan onnistumisen avaintekijöistä ja toiminnan kehittämisestä. Suuria näkemyseroja ei opettajien ja maatilojen kokemusten välillä ollut. Osapuolet pitivät maaseutua tärkeänä ja halusivat tarjota lapsille kokemuksia elämästä siellä. Yhteisenä tavoitteena opettajilla ja maatiloilla oli, että toiminta olisi mahdollisimman laajaa, ei pelkkiä retkipäiviä maalle. Opettajat korostivat myös vierailujen toiminnallisuutta. Maatilat toivoivat voivansa lisätä toiminnalla myös omaa tietämystään ja ammattitaitoaan. Käytännön asiat kuten matkat olivat eniten ongelmia aiheuttaneita asioita. Muina mahdollisina ongelmina mainittiin asenteet ja tiedotus. Toiminnan avaintekijöinä pidettiin suunnittelua, molempien osapuolten motivoituneisuutta ja aktiivisuutta, vierailujen toiminnallisuutta, tiedottamista ja toiminnan laajentamista. Kehittämisideat liittyivät toiminnan laajentamiseen ja monipuolistamiseen. Tämän tutkimuksen perusteella kummimaatilatoimintaa on ryhdytty kehittämään niin, että koko koululla yksittäisen luokan sijaan on yhteinen kummimaatila. Innovaatiotarkastelu osoitti, että kummimaatilatoiminnan kehittäminen ja levittäminen on pitkä prosessi, jossa koordinaattorin rooli on tärkeä. Osallistujien sitoutuminen toimintaan, osallistujien tukeminen sekä heidän kokemustensa hyödyntäminen on myös tärkeää. Tärkeimmät lähteet tutkimuksen taustateorian kannalta olivat Rogersin, Fullanin ja Hargreavesin teokset.

Trafficking and ethanol-induced inhibition of AMPA receptors

AMPA receptors are an important class of ionotropic glutamate receptors which participate in fast excitatory synaptic transmission in most brain areas. They have a pivotal role in adjustment of cell membrane excitability as their cell membrane expression levels is altered in brain physiology such as in learning and memory formation. AMPA receptor function and trafficking is regulated by several proteins, such as transmembrane AMPA receptor regulatory proteins (TARPs). NMDA-type glutamate receptors are important target molecules of ethanol. The role of AMPA receptors in the actions of ethanol has not been clarified as thoroughly. Furthermore, the regulation of AMPA receptor synthesis and their possible adaptation in neurons with altered inhibitory mechanisms are poorly understood. In this thesis work AMPA receptor pharmacology, trafficking and synaptic localization was studied using patch-clamp electrophysiology. Both native and recombinant AMPA receptors were studied. Hippocampal slices from transgenic Thy1alfa6 mice with altered inhibition were used to study adaptation of AMPA receptors. Ethanol was found to inhibit AMPA receptor function by increasing desensitization of the receptor, as the steady-state current was inhibited more than the peak current. Ethanol inhibition was reduced when cyclothiazide was used to block desensitization and when non-desensitizing mutant receptors were studied. Ethanol also increased the rate of desensitization, which was increased further by the coexpression of TARP-proteins. We found that the agonist binding capability is important for trafficking AMPA receptors from endoplasmic reticulum to the cell membrane. TARP rescues the surface expression of non-binding AMPA receptor mutants in HEK293 cells, but not in native neurons. Studies with Thy1alfa6 mice revealed that decreased inhibition decrease AMPA receptor mediated excitation keeping the neurotransmission in balance. Thy1alfa6 mice also had lower sensitivity to electroshock convulsions, presumably due to the decreased AMPA receptor function. The results suggest that during alcohol intoxication ethanol may inhibit AMPA receptors by increasing the rate and the extent of desensitization. TARPs appear to enhance ethanol inhibition. TARPs also participate in trafficking of AMPA receptors upon their synthesis in the cell. AMPA receptors mediate also long-term adaptation to altered neuronal excitability, which adds to their well-known role in synaptic plasticity.

Oral Actinomyces Species in Health and Disease: Identification, Occurence and Importance of Early Colonization

The genus Actinomyces consists of a heterogeneous group of gram-positive, mainly facultatively anaerobic or microaerobic rods showing various degrees of branching. In the oral cavity, streptococci and Actinomyces form a fundamental component of the indigenous microbiota, being among initial colonizers in polymicrobial biofilms. The significance of the genus Actinomyces is based on the capability of species to adhere to surfaces such as on teeth and to co-aggregate with other bacteria. Identification of Actinomyces species has mainly been based on only a few biochemical characteristics, such as pigmentation and catalase production, or on the use of a single commercial kit. The limited identification of oral Actinomyces isolates to species level has hampered knowledge of their role both in health and disease. In recent years, Actinomyces and related organisms have attracted the attention of clinical microbiologists because of a growing awareness of their presence in clinical specimens and their association with disease. This series of studies aimed to amplify the identification methods for Actinomyces species. With the newly developed identification scheme, the age-related occurrence of Actinomyces in healthy mouths of infants and their distribution in failed dental implants was investigated. Adhesion of Actinomyces species to titanium surfaces processed in various ways was studied in vitro. The results of phenotypic identification methods indicated a relatively low applicability of commercially available test kits for reliable identification within the genus Actinomyces. However, in the study of conventional phenotypic methods, it was possible to develop an identification scheme that resulted in accurate differentiation of Actinomyces and closely related species, using various different test methods. Genotypic methods based on 16S rRNA sequence analysis of Actinomyces proved to be a useful method for genus level identification and further clarified the species level identification with phenotypic methods. The results of the study of infants showed that the isolation frequency of salivary Actinomyces species increased according to age: thirty-one percent of the infants at 2 months but 97% at 2 years of age were positive for Actinomyces. A. odontolyticus was the most prominent Actinomyces colonizer during the study period followed in frequency by A. naeslundii and A. viscosus. In the study of explanted dental implants, Actinomyces was the most prevalent bacterial genus, colonizing 94% of the fixtures. Also in the implants A. odontolyticus was revealed as the most common Actinomyces species. It was present in 84% of Actinomyces -positive fixtures followed in frequency by A. naeslundii, A. viscosus and A. israelii. In an in vitro study of titanium surfaces, different Actinomyces species showed variation regarding their adhesion to titanium. Surface roughness as well as albumin coating of titanium had significant effects on adhesion. The use of improved phenotypic and molecular diagnostic methods increased the accuracy of the identification of the Actinomyces to species level. This facilitated an investigation of their occurrence and distribution in oral specimens in both health and disease.
