ABSTRACTThe aim of the study is to analyse teachers’ efforts to develop secondary school students’ knowledge and argumentation skills of what constitutes scientific theories. The analysis is based on Leontiev’s three-level structure of activity (activity, action, and operation), as these levels correspond to the questions why, what, and how content is taught. The unit of analysis was a school development project in science education, where design-based interventions were conducted. Data comprised notes and minutes from eight meetings, plans, and video recordings of the lessons, and a written teacher evaluation. The teachers’ (n = 7) learning actions were analysed to identify (a) concept formation in science education, (b) expressions of agency, (c) discursive manifestations of contradictions, and (d) patterns of interaction during the science interventions. Three lessons on what constitutes scientific theories were implemented in three different student groups (n = 24, 23, 24), framed by planning and evaluation meetings for each lesson. The results describe (1) the ways in which teachers became more skilled at ensuring instruction met their students’ needs and (2) the ways in which teachers’ operations during instruction changed as a result of their developed knowledge of how to express the content based on theoretical assumptions. 相似文献

This study explores the concept of link-making in relation to communicative strategies applied in the teaching and studying of biological evolution. The analysis focused on video recordings of 11 lessons on biological evolution conducted in a Swedish 9th grade class of students aged 15 years. It reveals how the teacher and students connected classroom conversations, the frequency of references to conversations in whole-class settings, and the development of a theme focusing on species survival and extinction. Detailed examples from the data illustrate how this theme developed from its initiation during the first lesson, through discussion and clarification, to its wrapping up during the last lesson. They further illustrate how students made sense of what the teacher said and wrote, and how the teacher postponed issues, explained and developed topics, provided opportunities for link-making, organised the class, motivated students, and checked their understanding. The study’s methodological approach offers a way of including several time dimensions within research. Based on our findings, we conclude that the excerpts examined here did succeed in building ‘islands of coherence’ in the co-construction of curricular content. Moreover, the topical trajectory in relation to species survival provided opportunities for constructing a ‘scientific story’ in the classroom. 相似文献

The Finnish system of religious education offers instruction in the pupil’s own religion or in ethics throughout comprehensive school. By taking the pupil’s background as a basis for instruction, this system aims at promoting equality and integration with respect to religion and one’s worldview. However, there has been little knowledge about how the system of instruction is experienced by pupils themselves and how it affects pupil’s identities at school. This study illuminates through a participant observation study in grades 1–6 how pupils in five minority instruction groups experience their classes and perceive themselves in relation to other pupils in school. The study shows how working in small groups represents an important element in pupils’ experiences. Pupils generally experienced participation in instruction as positive and fun, but age integration, organisation of schedules and classrooms were also important concerns. Even if pupils were content about having their own instruction group, feelings of otherness and a negative sense of difference in relation to the majority of pupils were found particularly among pupils of religion. 相似文献

The aim of this article is to investigate students’ meaning-making processes of multiple representations during a teaching sequence about the human body in lower secondary school. Two main influences are brought together to accomplish the analysis: on the one hand, theories on signs and representations as scaffoldings for learning and, on the other hand, pragmatist theories on how continuity between the purposes of different inquiry activities can be sustained. Data consist of 10 videotaped and transcribed lessons with 14-year-old students (N?=?26) in Sweden. The analysis focused instances where meaning of representations was negotiated. Findings indicate that continuity is established in multiple ways, for example, as the use of metaphors articulated as an interlanguage expression that enables the students (and the teacher) to maintain the conversation and explain pressing issues in ways that support of the end-in-view of the immediate action. Continuity is also established between every day and scientific registers and between organisation levels as well as between the smaller parts and the whole system. 相似文献
