Både internationellt och nationellt sett har elevers kunskaper i naturvetenskap försämrats enligt PISA-undersökningarna. Vi har även ute i verksamheten uppmärksammat en brist på kemiundervisning i de lägre åldrarna. Syftet med studien är att bidra med kunskap om ett vardagsnära och experimentellt arbetssätt och synlig- göra det naturvetenskapliga språkets betydelse för yngre elevers kunskapsutveckling i kemi. Studien utfördes som en aktionsforskning vilket innebär att en kunskapsbas skapas om sin egen praktik för att sedan genomföra en forskning som leder till en förändring. Aktionerna vi utförde bestod av två experiment med tillhörande för- och efterarbete. Aktionerna utfördes i en årskur ett och en årskurs två. Sammanlagt av 49 elever deltog 40 elever i studien. Dokumentationen bestod av elevernas stenciler från aktionerna, test, post-it lappar samt video- dokumentation från aktionerna och ljudupptagningar från fokusgruppssamtal. Studiens resulat visar att elevers förståelse för kemi kommer till uttryck genom ett experimentellt arbetssätt på flera olika sätt. Elever uttrycker sin förståelse då de kommunicera kring hypoteser, använder och förklarar begrepp, ger exempel på blandningar och lösningar, hittar kopplingar samt förklarar experimenten och dess resultat. Studiens övergripande slutsats är att ett experimentellt arbetssätt skapar möjligheter för eleverna att känna en glädje för kemin och en tilltro till sin egen förmåga. På vilket sätt lärare och elever använder språket i kemiundervisningen har stor betydelse för elevernas möjligheter att tillägna sig kunskaper i kemi. De didaktiska implikationer vi ser med studien är att det är fördelaktigt att arbeta med experiment i de yngre åldrarna. / Students´ knowledge of science have deteriorated both internationally and nationally PISA studies. We have also experienced a lack of chemistry teaching in the lower ages. The purpose of the study is to contribute with knowledge of an everyday related and an experimental approach and make visible the importance of the scientific language for younger pupils' knowledge in chemistry. The study was conducted as an action research which involves forming a knowledge based on their own practice and then conducts a research that leads to a change. The actions we performed consisted of two experiments with the associated pre- and after work. The study was conducted in year one and two with 40 of 49 students. The documentation consisted of students’ stencils, tests, post-it notes and videodocumentation. The study shows that the students' understanding of chemistry through an experimental approach is expressed in several different ways. Students express their understanding when they communicate about hypotheses, uses and explain concepts, giving examples of mixtures and solutions, find connections, and explain the experiments and their results. The study's overall conclusion is that an experimental approach creates opportunities for students to feel the joy of chemistry and a belief in their own ability. The way in which teachers and students use the language of chemistry teaching is of great importance for the students´ opportunities to acquire knowledge in chemistry. The didactic implications we see with the study is that it is beneficial to work with experiments in the younger ages.

This study is concerned with the development of subject knowledge in pre-service teachers of secondary physical education (PE) during their one year Physical Education Teacher Education (PETE) course. It investigates the knowledge bases for teaching which pre-service teachers recognised, developed and prioritised, as well as the key influences that impacted on their subject knowledge development. Adopting an interpretive methodology informed by constructivist grounded theory, the study employed interviews, lesson observations and post-lesson reflections as principal research methods. Pre-service teachers were seen to make wide-ranging progress in their subject knowledge, including the development of content knowledge, pedagogical content knowledge, general pedagogical knowledge, knowledge of curriculum and knowledge of pupils. Through this they advanced their view of the nature of PE and how they wanted to teach it. The research highlights, that the process of knowledge development in PETE is socially constructed and complex. Much of the pre-service teachers development was influenced by various communities of practice, particularly their school placements PE departments, but also their University-based learning community. Of these, the legitimised practices within the PE departments were found to be especially important to pre-service teachers development. University-based learning was credited by pre-service teachers with enhancing their holistic understanding of the learning process, developing those aspects of critical pedagogy that were under-developed in schools. The impact of different subject knowledge profiles and the consequences of knowledge deficits are identified. This raises questions about the role and development of subject knowledge within PETE and calls for a re-vitalised debate on the nature of the knowledge in PE. Framed within an ever-changing policy landscape is the need for enhanced and stable partnerships that promote shared visions of PETE, an essential part of which is the need to collaboratively design and evaluate explicit knowledge development pathways which allow pre-service teachers to fulfil their potential and genuinely decide how they want to teach PE.

Studien syftar att få kunskap om hur inspiration från Reggio Emilia filosofi kan användas som en pedagogisk resurs för lärandet för hållbar utveckling i förskolan. Huvudfrågan i arbetet är: Vilka metoder, strategier och synsätt använder pedagoger i lärandet för hållbar utveckling i förskolan? Kvalitativa intervjuer med förskollärare används som en metod för att uppnå studiesyftet och besvara frågan. Data analyserades för att visa vilka metoder och strategier pedagoger använder i lärandet för hållbar utveckling, samt att ta fram fördelar och hinder som finns i Reggio Emilias förhållningssätt i relation till lärandet. Studiens resultat visar att lärandet för hållbar utveckling i förskolan är en viktig del av förskoleverksamheten som hjälper barn att skapa en relation till naturen, utveckla kunskap, respekt och ansvar för natur och miljö. Pedagogerna jobbar för att ge barnen möjligheter att möta olika variationer av miljö och naturmaterial. Upplevelser som barn får i naturen väcker barns intresse, motivation och lust att lära sig för att veta mer om omvärlden. Barns intresse får styra lärandet. Lärandet sker i gruppen genom kommunikation och dialog, där barnen deltar aktivt i lärandet och skapar kunskap om natur och miljö. Medforskande närvarande förskollärare lär barn olika verktyg för att ta reda på saker själva. Värdegrundsarbete är det viktigaste området i lärandet för att barn ska utveckla respekt och ansvar för naturen. Fördelar i Reggio Emilia filosofi är syn på kompetenta barn, demokratiskt arbetssätt, inspirerande och stöttande lärandemiljö och pedagogisk dokumentation vilka hjälper att skapa kultur av hållbarhet och utveckla barns handlingsberedskap för en hållbar framtid. / The study aims to develop knowledge about how inspiration from Reggio Emilia's philosophy can be used as an educational resource for teaching about sustainable development in preschool. The main question is: Which methods, strategies and approaches do teachers use in learning for sustainable development in preschool? Qualitative interviews with preschool teachers are used as a method for achieving the aim of the study and answering the research question. The data has been analysed to indicate which methods and strategies preschool teachers use in learning for sustainable development, as well as to define advantage and barriers found in Reggio Emilia's philosophy in relation to that learning. The result shows that learning for sustainable development in preschool is an important part of preschool activities that helps children create a relationship with nature, develop knowledge, respect and responsibility for nature and the environment. The teachers work to give the children opportunities to meet different variations of the environment and natural materials. Experiences that children get in nature arouse children's interest, motivation and desire to learn to know more about nature and the environment. Children's interest may guide learning. This learning takes place in the group through communication and dialogue, where the children participate actively in learning and create knowledge about nature and the environment. The teachers introduce many different tools to the children to enable them to explore things by themselves. Working with fundamental values is the most important part of the learning to enhance children´s development of respect and sense of responsibility for nature. The advantages of Reggio Emilia philosophy are the view of children as competent, democratic working methods, inspirational and supportive learning environment and pedagogical documentation which help to create culture of sustain-ability and develop children's readiness for action for a sustainable future.

Problem Area/ Purpose  The purpose of this research is to study how geographically scattered employees learn and create new knowledge with the help of wiki tool in distributed software development process. We aim to analyze how wiki supports four modes of knowledge conversion process model and how wiki helps in solving the complex problem in virtual organization learning.  Research Methodology  In this research qualitative interview study was used. We have conducted the interview with eight developers and experts in the company. Nonaka and Takeuchi (1995) knowledge conversion model was used while conducting the interview with developers. Similarly, in this research same knowledge conversion model was used for interpreting the answers that we got from the developers and experts.  Findings/Conclusion  Wiki as a knowledge management tool is possible for providing effective as well as efficient communication as per necessity of knowledge requirement in distributed software organization. The use of wiki in the organization for the virtual learning is really beneficial for knowledge creation, solving the complex problem and obtaining the useful effect on virtual team. Some drawbacks were also seen by the expert and developers in using wiki. Those drawbacks were all about genuineness, authenticity, accuracy, trustworthy and uniqueness of knowledge content.  Research Limitation & Delimitations  Due to geographically dispersed location of research sites, we faced difficulty to gather information related to company documents, reports and contextual information of organization. We conducted this research in the offices of Pakistan and office in USA.   Outcomes  The research that we have conducted showed that the developers in Software Company can share knowledge and also can learn through different modes of knowledge conversion model. This research also showed that developers are using the wiki tool for creating new knowledge as well as solving complex problem. This research helps in showing the benefit for other company and motivates the virtual organizations for implementing the use of wiki for different purposes.

This dissertation takes its point of departure in a relational perspective on education, which means that the relationship between teacher and student is seen as fundamental for students’ knowledge- and personal development. The aim is to contribute to a deeper understanding of the teacher-student relationship in teacher education at national and local levels and the different meanings of closeness in this context.       The theoretical basis of the study is curriculum theory-based didactics, where questions about knowledge content and teaching as offering meaning are central. The thesis consists of three separate studies. The first investigates closeness in the teacher-student relationship by means of a thematic conceptual analysis of the field of research in educational science on teacher-student relationships. Four different dimensions of closeness were identified: closeness as presence, closeness as care, closeness as feeling and closeness as responsibility. The results show a nuanced way of understanding closeness in the teacher-student relationship and that closeness is challenging for teachers in that it makes their relational work more complex.      The central question in curriculum theory - ‘What opportunities do students have to learn about the teacher-student relationship in teacher education?’ - is used as the point of departure in the analysis of educational policy documents at national and local levels. The second study investigates content knowledge at the national level and shows a limited and simplified view of the relationship between teacher and student. By using the dimensions of closeness as analytical tools, a multifaceted teacher-student relationship is constructed as an alternative meaning offering. In the third study, eleven Swedish universities participated in the study of curriculum documents at the local level. The analysis showed three types of knowledge content: relational theory, relational work and relational quality. In this study, the local documents together provided a broad range of knowledge content, but individually a reduced and simplified knowledge content. The study also confirmed the differences between universities in their teacher education programmes and that there are often discrepancies in the knowledge content that is offered.      The thesis as a whole contributes to a nuanced understanding of closeness in the teacher-student relationship and provides a set of theoretical tools that can be used in an analysis of different types of research studies. It also indicates that the policy documents relating to teacher education at the national and local levels contain simplified and limited notions about the teacher-student relationship and teachers’ relational work as knowledge content. This restricted knowledge content could limit student teachers’ abilities to create, build and maintain good and close teacher-student relationships and to address the relational challenges in their complex relational work.
