Lifestyle of the Elderly Receiving Home Care in Spain

The aim of this study is to examine the lifestyle characteristics and health status of the elderly in order to identify aspects that might help promote active ageing. Participants were 26 elderly citizens aged 75 or over who were the recipients of home care services in Vilafranca del Penedès (Barcelona, Spain). They were recruited by means of convenience sampling, and a case study approach was adopted. Fieldwork was conducted in April 2007, with a specially designed questionnaire administered in the context of an in-depth interview. Quantitative data were analyzed with SPSS 15, while qualitative data were analysed and grouped by category. The results indicated that 53.8% of the elderly interviewees perceived their health status as being regular, most did not have adequate nutrition and hydration, while 42.3% had chewing problems and 65.3% presented slight dependence. Most of them received visits at home, but did not go on leisure outings. The only exercise they took was walking. These findings highlight the need to promote and strengthen activities for healthy ageing, and to ensure that people over 75 receive adequate care. Programmes should be implemented to improve those aspects that are currently under-addressed.

Evaluation of Teacher Education Programs by Students and Graduates

The purpose of this research was to do a repeated cross-sectional research on class teachers who study in the 4th year and also graduated at the Faculty of Education, University of Turku between the years of 2000 through 2004. Specifically, seven research questions were addressed to target the main purpose of the study: How do class teacher education masters’ degree senior students and graduates rate “importance; effectiveness; and quality” of training they have received at the Faculty of Education? Are there significant differences between overall ratings of importance; effectiveness and quality of training by year of graduation, sex, and age (for graduates) and sex and age (for senior students)? Is there significant relationship between respondents’ overall ratings of importance; effectiveness and their overall ratings of the quality of training and preparation they have received? Are there significant differences between graduates and senior students about importance, effectiveness, and quality of teacher education programs? And what do teachers’ [Graduates] believe about how increasing work experience has changed their opinions of their preservice training? Moreover the following concepts related to the instructional activities were studied: critical thinking skills, communication skills, attention to ethics, curriculum and instruction (planning), role of teacher and teaching knowledge, assessment skills, attention to continuous professional development, subject matters knowledge, knowledge of learning environment, and using educational technology. Researcher also tried to find influence of some moderator variables e.g. year of graduation, sex, and age on the dependent and independent variables. This study consisted of two questionnaires (a structured likert-scale and an open ended questionnaire). The population in study 1 was all senior students and 2000-2004 class teacher education masters’ degree from the departments of Teacher Education Faculty of Education at University of Turku. Of the 1020 students and graduates the researcher was able to find current addresses of 675 of the subjects and of the 675 graduates contacted, 439 or 66.2 percent responded to the survey. The population in study 2 was all class teachers who graduated from Turku University and now work in the few basic schools (59 Schools) in South- West Finland. 257 teachers answered to the open ended web-based questions. SPSS was used to produce standard deviations; Analysis of Variance; Pearson Product Moment Correlation (r); T-test; ANOVA, Bonferroni post-hoc test; and Polynomial Contrast tests meant to analyze linear trend. An alpha level of .05 was used to determine statistical significance. The results of the study showed that: A majority of the respondents (graduates and students) rated the overall importance, effectiveness and quality of the teacher education programs as important, effective and good. Generally speaking there were only a few significant differences between the cohorts and groups related to the background variables (gender, age). The different cohorts were rating the quality of the programs very similarly but some differences between the cohorts were found in the importance and effectiveness ratings. Graduates of 2001 and 2002 rated the importance of the program significantly higher than 2000 graduates. The effectiveness of the programs was rated significantly higher by 2001 and 2003 graduates than other groups. In spite of these individual differences between cohorts there were no linear trends among the year cohorts in any measure. In respondents’ ratings of the effectiveness of teacher education programs there was significant difference between males and females; females rated it higher than males. There were no significant differences between males’ and females’ ratings of the importance and quality of programs. In the ratings there was only one difference between age groups. Older graduates (35 years or older) rated the importance of the teacher training significantly higher that 25-35 years old graduates. In graduates’ ratings there were positive but relatively low correlations between all variables related to importance, effectiveness and quality of Teacher Education Programs. Generally speaking students’ ratings about importance, effectiveness and quality of teacher education program were very positive. There was only one significant difference related to the background variables. Females rated higher the effectiveness of the program. The comparison of students’ and graduates’ perception about importance, effectiveness, and quality of teacher education programs showed that there were no significant differences between graduates and students in the overall ratings. However there were differences in some individual variables. Students rated higher in importance of “Continuous Professional Development”, effectiveness of “Critical Thinking Skills” and “Using Educational Technology” and quality of “Advice received from the advisor”. Graduates rated higher in importance of “Knowledge of Learning Environment” and effectiveness of “Continuous Professional Development”. According to the qualitative data of study 2 some graduates expressed that their perceptions have not changed about the importance, effectiveness, and quality of training that they received during their study time. They pointed out that teacher education programs have provided them the basic theoretical/formal knowledge and some training of practical routines. However, a majority of the teachers seems to have somewhat critical opinions about the teacher education. These teachers were not satisfied with teacher education programs because they argued that the programs failed to meet their practical demands in different everyday situations of the classroom e.g. in coping with students’ learning difficulties, multiprofessional communication with parents and other professional groups (psychologists and social workers), and classroom management problems. Participants also emphasized more practice oriented knowledge of subject matter, evaluation methods and teachers’ rights and responsibilities. Therefore, they (54.1% of participants) suggested that teacher education departments should provide more practice-based courses and programs as well as closer collaboration between regular schools and teacher education departments in order to fill gap between theory and practice.

The effects of ICT on school: teachers’ and students’ perspectives

The purpose of this study was to investigate the effects of information and communication technology (ICT) on school from teachers’ and students’ perspectives. The focus was on three main subject matters: on ICT use and competence, on teacher and school community, and on learning environment and teaching practices. The study is closely connected to the national educational policy which has aimed strongly at supporting the implementation of ICT in pedagogical practices at all institutional levels. The phenomena were investigated using a mixed methods approach. The qualitative data from three cases studies and the quantitative data from three statistical studies were combined. In this study, mixed methods were used to investigate the complex phenomena from various stakeholders’ points of view, and to support validation by combining different perspectives in order to give a fuller and more complete picture of the phenomena. The data were used in a complementary manner. The results indicate that the technical resources for using ICT both at school and at homes are very good. In general, students are capable and motivated users of new technology; these skills and attitudes are mainly based on home resources and leisuretime use. Students have the skills to use new kinds of applications and new forms of technology, and their ICT skills are wide, although not necessarily adequate; the working habits might be ineffective and even wrong. Some students have a special kind of ICT-related adaptive expertise which develops in a beneficial interaction between school guidance and challenges, and individual interest and activity. Teachers’ skills are more heterogeneous. The large majority of teachers have sufficient skills for everyday and routine working practices, but many of them still have difficulties in finding a meaningful pedagogical use for technology. The intensive case study indicated that for the majority of teachers the intensive ICT projects offer a possibility for learning new skills and competences intertwined in the work, often also supported by external experts and a collaborative teacher community; a possibility that “ordinary” teachers usually do not have. Further, teachers’ good ICT competence help them to adopt new pedagogical practices and integrate ICT in a meaningful way. The genders differ in their use of and skills in ICT: males show better skills especially in purely technical issues also in schools and classrooms, whereas female students and younger female teachers use ICT in their ordinary practices quite naturally. With time, the technology has become less technical and its communication and creation affordances have become stronger, easier to use, more popular and motivating, all of which has increased female interest in the technology. There is a generation gap in ICT use and competence between teachers and students. This is apparent especially in the ICT-related pedagogical practices in the majority of schools. The new digital affordances not only replace some previous practices; the new functionalities change many of our existing conceptions, values, attitudes and practices. The very different conceptions that generations have about technology leads, in the worst case, to a digital gap in education; the technology used in school is boring and ineffective compared to the ICT use outside school, and it does not provide the competence needed for using advanced technology in learning. The results indicate that in schools which have special ICT projects (“ICT pilot schools”) for improving pedagogy, these have led to true changes in teaching practices. Many teachers adopted student-centred and collaborative, inquiry-oriented teaching practices as well as practices that supported students' authentic activities, independent work, knowledge building, and students' responsibility. This is, indeed, strongly dependent on the ICT-related pedagogical competence of the teacher. However, the daily practices of some teachers still reflected a rather traditional teacher-centred approach. As a matter of fact, very few teachers ever represented solely, e.g. the knowledge building approach; teachers used various approaches or mixed them, based on the situation, teaching and learning goals, and on their pedagogical and technical competence. In general, changes towards pedagogical improvements even in wellorganised developmental projects are slow. As a result, there are two kinds of ICT stories: successful “ICT pilot schools” with pedagogical innovations related to ICT and with school community level agreement about the visions and aims, and “ordinary schools”, which have no particular interest in or external support for using ICT for improvement, and in which ICT is used in a more routine way, and as a tool for individual teachers, not for the school community.

Competitive flexibility in systems supplier companies in mechanical engineering industry

Systems suppliers are focal actors in mechanical engineering supply chains, in between general contractors and component suppliers. This research concentrates on the systems suppliers’ competitive flexibility, as a competitive advantage that the systems supplier gains from independence from the competitive forces of the market. The aim is to study the roles that power, dependence relations, social capital, and interorganizational learning have on the competitive flexibility. Research on this particular theme is scarce thus far. The research method applied here is the inductive multiple case study. Interviews from four case companies were used as main source of the qualitative data. The literature review presents previous literature on subcontracting, supply chain flexibility, supply chain relationships, social capital and interorganizational learning. The result of this study are seven propositions and consequently a model on the effects that the dominance of sales of few customers, power of competitors, significance of the manufactured system in the end product, professionalism in procurement and the significance of brand products in the business have on the competitive flexibility. These relationships are moderated by either social capital or interorganizational learning. The main results obtained from this study revolve around social capital and interorganizational learning, which have beneficial effects on systems suppliers’ competitive flexibility, by moderating the effects of other constructs of the model. Further research on this topic should include quantitative research to provide the extent to which the results can be reliably generalized. Also each construct of the model gives possible focus for more thorough research.

Development of an instrument to measure the degree of critical patient's satisfaction with nursing care: research protocol

Aim: To investigate and understand patient's satisfaction with nursing care in the intensive care unit to identify the dimensions of the concept of"satisfaction" from the patient's point of view. To design and validate a questionnaire that measures satisfaction levels in critical patients. Background: There are many instruments capable of measuring satisfaction with nursing care; however, they do not address the reality for critical patients nor are they applicable in our context. Design: A dual approach study comprising: a qualitative phase employing Grounded Theory and a quantitative and descriptive phase to prepare and validate the questionnaire. Methods: Data collection in the qualitative phase will consist of: in-depth interview after theoretical sampling, on-site diary and expert discussion group. The sample size will depend on the expected theoretical saturation n = 27-36. Analysis will be based on Grounded Theory. For the quantitative phase, the sampling will be based on convenience (n = 200). A questionnaire will be designed on the basis of qualitative data. Descriptive and inferential statistics will be used. The validation will be developed on the basis of the validity of the content, the criteria of the construct and reliability of the instrument by the Cronbach's alpha and test-retest approach. Approval date for this protocol was November 2010. Discussion: Self-perceptions, beliefs, experiences, demographic, socio-cultural epistemological and political factors are determinants for satisfaction, and these should be taken into account when compiling a questionnaire on satisfaction with nursing care among critical patients.

Laboratory projects using inquiry-based learning: an application to a practical inorganic course

This paper reports how laboratory projects (LP) coupled to inquiry-based learning (IBL) were implemented in a practical inorganic chemistry course. Several coordination compounds have been successfully synthesised by students according to the proposed topics by the LP-IBL junction, and the chemistry of a number of metals has been studied. Qualitative data were collected from written reports, oral presentations, lab-notebook reviews and personal discussions with the students through an experimental course with undergraduate second-year students at the Universidad Nacional de Colombia during the last 5 years. Positive skills production was observed by combining LP and IBL. Conceptual, practical, interpretational, constructional (questions, explanations, hypotheses), communicational, environmental and application abilities were revealed by the students throughout the experimental course.

Luottamuksen ilmeneminen alueellisissa yhteistyöverkostoissa

Appearance of trust in regional, co-operative networks In our times, the value of social networks has been widely acknowledged. One can say that it is important for private persons to get networked, whilst it is even a must for companies and organizations in business life. This doctor's thesis examines three co-operative regional networks. Networks are located in Western Uusimaa (Länsi-Uusimaa) region in southernmost Finland, and they had both public organizations and private companies as participants (later called ‘players’). Initially, all of them were co-financed from public funds, and two of them are still operational while writing this. The main target of these networks has been to act as learning networks. The learning network stands for an ensemble of research and development units and workplaces constituting a common forum for learning. The main focus in this study has been on qualitative and structural characteristics of the networks, and how they are relating with intrinsic trust. In addition to the development of trust, it has been studied, at what level organizational learning within the networks takes place, and lastly, what kind of factors facilitate the development of social capital. The theoretical framework for the study is built on analysing trust and social capital. It is a 'mission impossible' to find single definitions for such major concepts. In this study, from the research questions' point of view it has been more relevant to concentrate on the aspects of networking and the relationships between the participating organizations. The total view in this study is very network-centric, and therefore those theories which have similar point of view have been prioritized. Such is the theory about structural holes by Ronald S. Burt (1992). It has been widely applied; especially his views on constraints affecting players in networks. The purpose of this study has not been to create new theories or to analyse and compare thoroughly the existing theoretical trends. Instead, the existing theories have provided the study with conceptual tools, which have been utilized for supporting the empirical results. The aim has been to create an explanatory case study consisting relevant discussion on the relationship between the network characteristics and the appearance of trust. The conceptual categorization for confidence vs. trust created by Niklas Luhmann (1979) is another important theoretical building block. In most cases, co-operation in networks is initiated by people already trusting in each other and willing to work together. However, personal trust is not sufficient in the long run to sustain the co-operation within the network: more abstract systemic trust described by Luhmann must also emerge. In the networks with different structures and at different development phases, these forms of trust appear at different levels. In this study, Luhmann’s systemic trust as a term has been replaced by the concept of 'trust in network as a system'. Structural characteristics of a network (density, centrality, structural holes etc.) have been selected to explain the creation of social capital and trust. The ability to adapt new information is essential for the development of social capital. Qualitative analysis for development phase has been used, and the Learning Network Maturity Test by Leenamaija Otala (2000) and her work have been applied. Thus, the qualitative characteristics and the structural characteristics of the networks are utilized together, when the creation of social capital and appearance of trust are assessed. Social Network Analysis, questionnaires and interviews have been the research methods. Quantitative and qualitative data have been combined. There is a similarity in viewpoints to research data with Extensive Case Study method, in which different cases are searched by exploring various cases and comparing certain common features between them and generic models. Development of trust, social capital and organizational learning has been explained in the study by comparing the networks in hand. Being a case study, it doesn't have targets to provide with general results and findings like conventional surveys. However, in this work phenomena and mechanisms related to them are interpreted from the empirical data. Key finding of this study is that the networks with high structural equality and clear target setting enable building trust to the network as a system. When systemic trust is present, e.g. changes in personnel involved in the co-operation won't hinder the network from remaining operational. On the other hand, if the players are not well motivated to co-operate, if the network is extremely centralized structurally, or if the network has players holding very much more beneficial position compared to the others, systemic trust won't develop: trust tends to remain at the personal level, and is directed to some players only. Such networks won't generate results and benefits to its players, and most probably they won’t live very long. In other words, learning networks cannot solely be based on willingness to learn, but also on willingness to co-operate.

Parallella, dynamiska representationer i gymnasiefysiken : implementering av ett interaktivt datorverktyg i didaktiska situationer och uppfattning av effektivt lärande

The computer is a useful tool in the teaching of upper secondary school physics, and should not have a subordinate role in students' learning process. However, computers and computer-based tools are often not available when they could serve their purpose best in the ongoing teaching. Another problem is the fact that commercially available tools are not usable in the way the teacher wants. The aim of this thesis was to try out a novel teaching scenario in a complicated subject in physics, electrodynamics. The didactic engineering of the thesis consisted of developing a computer-based simulation and training material, implementing the tool in physics teaching and investigating its effectiveness in the learning process. The design-based research method, didactic engineering (Artigue, 1994), which is based on the theoryof didactical situations (Brousseau, 1997), was used as a frame of reference for the design of this type of teaching product. In designing the simulation tool a general spreadsheet program was used. The design was based on parallel, dynamic representations of the physics behind the function of an AC series circuit in both graphical and numerical form. The tool, which was furnished with possibilities to control the representations in an interactive way, was hypothesized to activate the students and promote the effectiveness of their learning. An effect variable was constructed in order to measure the students' and teachers' conceptions of learning effectiveness. The empirical study was twofold. Twelve physics students, who attended a course in electrodynamics in an upper secondary school, participated in a class experiment with the computer-based tool implemented in three modes of didactical situations: practice, concept introduction and assessment. The main goal of the didactical situations was to have students solve problems and study the function of AC series circuits, taking responsibility for theirown learning process. In the teacher study eighteen Swedish speaking physics teachers evaluated the didactic potential of the computer-based tool and the accompanying paper-based material without using them in their physics teaching. Quantitative and qualitative data were collected using questionnaires, observations and interviews. The result of the studies showed that both the group of students and the teachers had generally positive conceptions of learning effectiveness. The students' conceptions were more positive in the practice situation than in the concept introduction situation, a setting that was more explorative. However, it turned out that the students' conceptions were also positive in the more complex assessment situation. This had not been hypothesized. A deeper analysis of data from observations and interviews showed that one of the students in each pair was more active than the other, taking more initiative and more responsibilityfor the student-student and student-computer interaction. These active studentshad strong, positive conceptions of learning effectiveness in each of the threedidactical situations. The group of less active students had a weak but positive conception in the first iv two situations, but a negative conception in the assessment situation, thus corroborating the hypothesis ad hoc. The teacher study revealed that computers were seldom used in physics teaching and that computer programs were in short supply. The use of a computer was considered time-consuming. As long as physics teaching with computer-based tools has to take place in special computer rooms, the use of such tools will remain limited. The affordance is enhanced when the physical dimensions as well as the performance of the computer are optimised. As a consequence, the computer then becomes a real learning tool for each pair of students, smoothly integrated into the ongoing teaching in the same space where teaching normally takes place. With more interactive support from the teacher, the computer-based parallel, dynamic representations will be efficient in promoting the learning process of the students with focus on qualitative reasoning - an often neglected part of the learning process of the students in upper secondary school physics.

Lapsen sosiaalisen kompetenssin tukeminen – vanhempien epäsuorat ja suorat vaikutustavat

Tässä tutkimuksessa tarkastellaan vanhempien havaintoja ja käsityksiä lapsen sosiaalisesta kompetenssista. Lapsen sosiaalisesta kompetenssista tarkastelun kohteena ovat erityisesti vertaissuhteet, sosiaaliset taidot ja sosiaalinen käyttäytyminen. Tarkoituksena on selvittää vanhempien näkemyksiä lapsen sosiaalisesta verkostosta ja lapsesta sosiaalisena toimijana. Kiinnostuksen kohteena on myös, miten vanhemmat vaikuttamaan lapsen sosiaaliseen kompetenssiin. Vanhempien vaikutuksessa voidaan erottaa epäsuora ja suora vaikutus. Vanhempien epäsuoraan vaikutukseen kuuluvat perheen sosioekonomiset tekijät, vanhemmuuteen ja lastenkasvatukseen liittyvät käytännöt sekä lapsen ja vanhemman välinen vuorovaikutus. Suora vaikutus sisältää vanhempien eri roolit ja tehtävät sosiaalisen kompetenssin edistämiseksi. Vanhempien epäsuorilla ja suorilla vaikutustavoilla on havaittu olevan merkittävää vaikutusta lapsen sosiaalisen kompetenssiin muotoutumiseen ja sen laatuun. Tutkimuksessa selvitetään vertaissuhdeongelmaisten ja ei-ongelmaisten lasten vanhempien välisiä eroja näissä vaikutustavoissa. Tutkimuksessa hyödynnetään kyselylomake- ja haastatteluaineistoja. Kyselylomakeaineisto (N=156) kerättiin ”Origins of Exclusion in Early Childhood”-tutkimusprojektissa, jossa tutkittiin lasten vertaissuhteita, sosiaalisia taitoja sekä sosiaalista käyttäytymistä kolmen vuoden seurantatutkimuksena päiväkodista kouluun. Perhekysely toteutettiin lasten ollessa kuusivuotiaita. Vanhempien haastatteluaineisto (N=55) koostuu projektissa mukana olleiden lasten vanhempien teemahaastatteluista. Perhekyselyä analysoidaan tilastollisin analyysimenetelmin. Laadullisen aineiston analyysimenetelmänä käytetään sisällönanalyysia. Vanhempien käsityksissä lasten sosiaalinen verkosto rakentui kotiympäristössä, koulussa, päiväkodissa sekä suvun ja harrastusten parissa muodostuneista suhteista. Tutkimustulosten perusteella on havaittavissa, että vertaissuhdeongelmaisten ja ei-ongelmaisten lasten sosiaaliset verkostot ovat osin erilaiset. Vanhempien arviointien mukaan myös lasten sosiaalisissa taidoissa, käyttäytymisessä, asennoitumisessa sosiaaliseen kanssakäymiseen sekä ryhmään ja leikkeihin liittyvissä strategioissa on eroavaisuuksia. Tutkimuksen pohjalta voidaan todeta, että vanhemmat pystyvät arvioimaan hyvin yksityiskohtaisesti lapsensa sosiaalisia taitoja ja käyttäytymistä. Kaikilla vanhemmilla ei kuitenkaan ollut riittävästi tietoa lasten kaveripiiristä tai sen laadusta eikä lasten sosiaalisesta orientaatiosta. Vanhempien epäsuorissa vaikutustavoissa oli eroja, mutta myös yhtäläisyyksiä. Sosioekonomisia tekijöitä koskevan tarkastelun perusteella vertaissuhdeongelmaisten lasten perheiden taloudelliset ongelmat, isien työttömyys ja lapsen erityisen tuen tarve olivat yhteydessä lapsen sosiaalisten suhteiden ongelmiin. Lähes kaikki tutkimukseen osallistuneet vanhemmat kokivat vanhemmuuden ja kasvatustehtävän kuitenkin hyvin myönteisenä ja tyytyväisyyttä tuottavana asiana elämässä. Valtaosa vanhemmista piti lapsen ja aikuisen välistä vuorovaikutusta positiivisena, vaikka lapsen kanssa ei aina ollutkaan helppoa tulla toimeen. Tyytyväisyydestä huolimatta äidit näkivät itsessään enemmän kehittymisen tarpeita vanhempana kuin isät. Vanhemmuudessa korostuivat ohjaaminen ja kontrolli, mutta myös hoiva, lämpö ja vastavuoroisuus. Hoiva ja lämpö sekä rajojen asettaminen askarruttivat vanhempia suuresti. Vertaissuhdeongelmaisten lasten vanhemmat tarvitsisivat opastusta ohjaavan vanhemmuuden löytämiseksi. Vertaissuhdeongelmaisten lasten vanhemmat kuvasivat kasvatuksen kuormittavuutta, ajan puutetta sekä muuntuvaa isyyttä ja äitiyttä ei-ongelmaisten lasten vanhempia enemmän. Työn ja perheen yhteensovittamisen vaikeus tuli myös esille vanhempien kuvauksissa. Kyvykkään vanhemmuuden kannalta epävirallinen läheisistä muodostunut tukiverkosto on tärkeä vanhemman apu ja kasvatuksen turva. Ensisijaisena tukitahona on epävirallinen verkosto, joka koostuu ystävistä, tuttavista, työtovereista, puolisosta ja omista vanhemmista. Vertaissuhdeongelmaisten lasten vanhempien mukaan arjen tukea ei kuitenkaan ole aina saatavilla, eikä tukiverkosto tyydyttänyt vanhempia. Vanhempien käsityksissä perheen vuorovaikutus sujui hyvin ja vastuu kodista ja kasvatustehtävästä oli molemmilla vanhemmilla tasavertaisesti. Käytännön vastuu kasvatuksesta sekä erilaisten taitojen opettamisesta lapsille kuului äitien tehtäviin. Vanhempien näkemyksissä lapsen sosiaalinen maailma rakentui lähiympäristön tarjoamista mahdollisuuksista. Vanhempien suoriin vaikutustapoihin liittyvien tulosten mukaan vanhemmat pitävät harrastuksia merkittävänä sosiaalista kompetenssia edistävänä tekijänä. Ei-ongelmaisilla lapsilla oli enemmän ja monipuolisempia harrastuksia kuin ongelmaisilla lapsilla. Vaikka vanhemmat eivät mieltäneetkään omaa toimintaansa kaveripiiriin ohjaamiseksi, heillä useinkin oli runsaasti erilaisia rooleja ja tehtäviä sosiaalisten suhteiden ja sosiaalisten taitojen opettamisessa. Lapsen sosiaalisten suhteiden organisoinnissa, ohjaamisessa, valvonnassa ja neuvonnassa oli vanhempiryhmien välillä eroja. Vertaissuhdeongelmaisten lasten vanhemmat eivät olleet riittävän hyvin perillä lapsen taidoista ja kyvykkyydestä tuottaakseen oikea-aikaista ohjausta ja tukeakseen lasta riittävästi sopivilla tavoilla. Vanhempien toimintaa näyttää ohjaavan vakaasti se uskomus, että lapsen kaverisuhteet ovat pelkästään hänen oma asiansa. Vanhemmat arvostivat paljon sosiaalisia taitoja ja pyrkivät opettamaan niitä lapsilleen systemaattisesti. Ohjaamisen tavoissa vanhemmat poikkesivat toisistaan. Tutkimus antaa viitteitä, että eiongelmaisten lasten vanhemmat ovat sensitiivisempiä, vastavuoroisempia ja lapsen näkökulmaa ja tarpeita lähtökohtanaan pitäviä sekä tunnetaitoihin ja tunnetilan käsittelyyn keskittyvämpiä kuin ongelmaisten lasten vanhemmat. Vanhempien ja lasten vuorovaikutuksen vaikeudet, ylimalkainen ja epäjohdonmukainen sosiaalisten taitojen, käyttäytymisen sekä suhteiden ohjaus sekä monet perheen voimavarojen puutteet voivat haitata vakavasti lapsen sosiaalisen kompetenssin kehittymistä. Vanhemmilla on kuitenkin taitoa arvioida lapsensa sosiaalista kyvykkyyttä ja halua toimia hyvin kasvatustehtävässään.

Determination of slurry’s viscosity using case based reasoning approach

Case-based reasoning (CBR) is a recent approach to problem solving and learning that has got a lot of attention over the last years. In this work, the CBR methodology is used to reduce the time and amount of resources spent on carry out experiments to determine the viscosity of the new slurry. The aim of this work is: to develop a CBR system to support the decision making process about the type of slurries behavior, to collect a sufficient volume of qualitative data for case base, and to calculate the viscosity of the Newtonian slurries. Firstly in this paper, the literature review about the types of fluid flow, Newtonian and non-Newtonian slurries is presented. Some physical properties of the suspensions are also considered. The second part of the literature review provides an overview of the case-based reasoning field. Different models and stages of CBR cycles, benefits and disadvantages of this methodology are considered subsequently. Brief review of the CBS tools is also given in this work. Finally, some results of work and opportunities for system modernization are presented. To develop a decision support system for slurry viscosity determination, software application MS Office Excel was used. Designed system consists of three parts: workspace, the case base, and section for calculating the viscosity of Newtonian slurries. First and second sections are supposed to work with Newtonian and Bingham fluids. In the last section, apparent viscosity can be calculated for Newtonian slurries.

Playing to Learn: Business Simulation Games as Leadership Learning Environments

The aim of this dissertation is to investigate if participation in business simulation gaming sessions can make different leadership styles visible and provide students with experiences beneficial for the development of leadership skills. Particularly, the focus is to describe the development of leadership styles when leading virtual teams in computer-­supported collaborative game settings and to identify the outcomes of using computer simulation games as leadership training tools. To answer to the objectives of the study, three empirical experiments were conducted to explore if participation in business simulation gaming sessions (Study I and II), which integrate face-­to-­face and virtual communication (Study III and IV), can make different leadership styles visible and provide students with experiences beneficial for the development of leadership skills. In the first experiment, a group of multicultural graduate business students (N=41) participated in gaming sessions with a computerized business simulation game (Study III). In the second experiment, a group of graduate students (N=9) participated in the training with a ‘real estate’ computer game (Study I and II). In the third experiment, a business simulation gaming session was organized for graduate students group (N=26) and the participants played the simulation game in virtual teams, which were organizationally and geographically dispersed but connected via technology (Study IV). Each team in all experiments had three to four students and students were between 22 and 25 years old. The business computer games used for the empirical experiments presented an enormous number of complex operations in which a team leader needed to make the final decisions involved in leading the team to win the game. These gaming environments were interactive;; participants interacted by solving the given tasks in the game. Thus, strategy and appropriate leadership were needed to be successful. The training was competition-­based and required implementation of leadership skills. The data of these studies consist of observations, participants’ reflective essays written after the gaming sessions, pre-­ and post-­tests questionnaires and participants’ answers to open-­ ended questions. Participants’ interactions and collaboration were observed when they played the computer games. The transcripts of notes from observations and students dialogs were coded in terms of transactional, transformational, heroic and post-­heroic leadership styles. For the data analysis of the transcribed notes from observations, content analysis and discourse analysis was implemented. The Multifactor Leadership Questionnaire (MLQ) was also utilized in the study to measure transformational and transactional leadership styles;; in addition, quantitative (one-­way repeated measures ANOVA) and qualitative data analyses have been performed. The results of this study indicate that in the business simulation gaming environment, certain leadership characteristics emerged spontaneously. Experiences about leadership varied between the teams and were dependent on the role individual students had in their team. These four studies showed that simulation gaming environment has the potential to be used in higher education to exercise the leadership styles relevant in real-­world work contexts. Further, the study indicated that given debriefing sessions, the simulation game context has much potential to benefit learning. The participants who showed interest in leadership roles were given the opportunity of developing leadership skills in practice. The study also provides evidence of unpredictable situations that participants can experience and learn from during the gaming sessions. The study illustrates the complex nature of experiences from the gaming environments and the need for the team leader and role divisions during the gaming sessions. It could be concluded that the experience of simulation game training illustrated the complexity of real life situations and provided participants with the challenges of virtual leadership experiences and the difficulties of using leadership styles in practice. As a result, the study offers playing computer simulation games in small teams as one way to exercise leadership styles in practice.

”Hei, mä opin tän asian enkuks!” Toimintatutkimus ympäristötiedon ainesisältöjen ja vieraan kielen oppimisesta sekä opettamisesta englanninkielissä oppituokioissa

Tämä kvalitatiivinen toimintatutkimus sai lähtökipinän opettajan tarpeesta kehittää englannin kielen opetustaan suuntaan, joka innostaisi oppijoita opiskelemaan ja tuottamaan vierasta kieltä rohkeasti. Tutkimuksen tarkoituksena oli selvittää, mitä muutoksia oppijoissa ilmenee, kun perinteiseen vieraan kielen opetukseen sisällytetään kahden lukuvuoden ajan oppituokioita, joissa ympäristötiedon ainesisältöjä opetetaan vieraalla kielellä. Kiinnostuksen kohteena oli tutkia, ilmeneekö oppijoilla muutoksia ainesisältöjen hallinnassa, englanninkielisen ympäristötiedon sanavaraston karttumisessa, kielitaidon kehittymisessä sekä asenteessa oppituokioita ja englannin kieltä kohtaan yleensä. Tutkimuksen tarkoituksena oli myös luoda toimivaa käytäntöä opettajalle toteuttaa ainesisältöjen opettamista vieraalla kielellä, josta kansainvälisesti käytetään termiä Content and language integrated learning (CLIL). Tutkimus oli kahden vuoden pitkittäistutkimus, joka toteutettiin lukuvuosina 2008–2010. Tutkimusjoukko koostui 18:sta (11 poikaa ja 7 tyttöä) neljättä luokkaa aloittavasta oppijasta. Vertailuryhmään kuului 22 musiikkiluokan oppijaa (6 poikaa ja 16 tyttöä). Tutkija opetti molemmille ryhmille englannin kieltä kaksi viikkotuntia. Englanninkieliset oppituokiot toteutettiin englannin tuntien yhteydessä noin kerran viikossa. Kerrallaan tuokio kesti 15–20 minuuttia. Tutkimusaineistoa, joka koostuu sekä kvalitatiivisesta että kvantitatiivisesta aineistosta, kerättiin eri tavoin: tutkija keräsi havaintomateriaalia päiväkirjaansa koko tutkimuksen ajan, oppijoita testattiin kuusi kertaa tutkimuksen aikana sekä itsearvio- ja asennekyselyjä toteutettiin kahdesti. Tutkimusaineiston pohjalta saatiin selviä tutkimustuloksia, joiden mukaan CLIL-opetus vaikutti oppijoihin positiivisesti: ympäristötiedon ainesisältöjä opittiin, englanninkielinen ympäristötiedon sanavarasto laajeni ja vierasta kieltä käytettiin rohkeammin kuin aiemmin. Kommunikoidessa huomio kiinnitettiin kielen tarkkailun sijasta asiasisältöön. Oppijat suhtautuivat englanninkielisiin oppituokioihin positiivisesti ja englannin osaaminen koettiin tärkeäksi. Tässäkin kokeilussa CLIL osoittautui joustavaksi metodiseksi lähestymistavaksi, joka taipuu käyttökelpoiseksi käytännön teoriaksi soveltuen monenlaisille oppijoille.
