This study draws on recent research on the central role of representation in learning. While there has been considerable research
on students’ understanding of evaporation, the representational issues entailed in this understanding have not been investigated
in depth. The study explored students’ engagement with evaporation phenomena through various representational modes. The study
indicates how a focus on representation can provide fresh insights into the conceptual task involved in learning science through
an investigation of students’ responses to a structured classroom sequence and subsequent interviews over a year. A case study
of one child’s learning demonstrates the way conceptual advances are integrally connected with the development of representational
modes. The findings suggest that teacher-mediated negotiation of representational issues as students construct different modal
accounts can support enriched learning by enabling both (a) richer conceptual understanding by students, and (b) enhanced
teacher insights into students’ thinking. 相似文献

A study of primary teacher trainees' perceptions and attitudes to science in 1990, has been useful in designing a semester
unit aimed at increasing the confidence and interest of first year students at Victoria College. This paper outlines the background
survey and discusses some, of the results and how they were used to develop the Professional Readiness Study-Understanding
Science. This unit attempts to change attitudes by focussing on metacognition and encourages students to understand and control
their own learning. Discussion involves teaching and learning strategies and alternative assessment approaches including the
student's journal-the Personal Record.

Despite mixed results in research on student learning from drawing in science, there is growing interest in the potential for this visual mode, in tandem with other modes, to enact and enable student reasoning in this subject. Building on current research in this field, and using a micro-ethnographic approach informed by socio-semiotic perspectives, we aimed to identify how and why student drawing can contribute to student reasoning and learning. In our study, secondary school students were challenged to explore and collaboratively create explanatory representations of phenomena including through drawing. Data were generated using multiple wall- and ceiling-mounted cameras capable of continuously tracking groups of students negotiating these representational challenges. Our analysis proceeded through active and iterative viewing of the extensive video record, and the identification of themes to establish possible relationships between drawing and reasoning. Through this process, we (a) identify multiple necessary conditions and varied opportunities for student drawing to enact and enable reasoning, and (b) extend current understandings of how the particular affordances of this mode interact with these conditions to contribute to student learning in science. 相似文献

Conclusion These case studies offer strong support for the notion that learning occurs naturally and inevitably when it flows out of
a student's desire to extend her own interests and experiences. This view was expressed strongly by the progressives (Dewey
[1963], and Kilpatrick [1928, 1952:315]) and more recently by Wilson (1971). They also represent “instances of autonomy” that
challenge our normal assumptions of student behaviour.
There are, of course, matters of the transmission of those “storehouses of knowledge” that represent the disciplines, and
matters of practicality in motivating and managing a class of students pursuing their own interests (Tytler 1983), that would
make it impractical to centre all teaching around the IRP or its equivalent. The need to include IRP's at a significant place
within the curriculum, however, is indicated not only by the student outcomes that have emerged in this study, but from the
fact that an increasing number of teachers have found it to be a satisfying method, involving a more powerful and natural
view of the student in relation to the educational process (Tytler, ibid).
The case studies have something to say about all such activities (other possibilities are described in Boomer [1983]) that
invite students to take responsibility for the serious development of their interests. They stand as examples of the way students
work outside the classroom, but also as celebrations of student independence and autonomy. Too often the schooling practices
we subscribe to tend to invalidate students' own life experiences. These case studies provide a challenge to us to find educative
ways that can match the range of abilities and dispositions that students bring with then to school. 相似文献

A range of challenging activities centred on evaporation and condensation were explored with year 1 and year 6 children. Their explanations in group discussion, written responses and interview were analysed, using NUD*IST qualitative analysis software, to explore the nature and coherence of their conceptions. The data was used to critically evaluate previous claims in the literature concerning the characteristics of progression in understanding of evaporation, and to identify the main dimensions that characterize the differences in children's explanations. The older children displayed a surer sense of ontological categories, greater epistemological sophistication including their ability to link explanations and evidence, greater precision in the use of conceptual language, and a greater range of associations they could make. 相似文献

Deconstructing learning in science—Young children's responses to a classroom sequence on evaporation 总被引：1，自引：0，他引：1
Five year old children's ideas were tracked by a range of means during and subsequent to a classroom sequence on evaporation.
They held a range of conceptions which changed in complex ways across context and time. These could only be made sense of
by moving outside traditional conceptual change interpretations to include broader notions of appropriation of language as
a cultural tool, of personal and social narrative responses to features of the phenomena and the classroom setting, and the
nature of science explanations. The findings are used to explore the relationship between social and individual perspectives
on learning, and to question some assumptions underlying conceptual change research. 相似文献

Children's responses to a series of air pressure activities were tracked in detail during group discussion and interview, and again in interview six months later. Results for different age cohorts have yielded insights into age‐related knowledge components framing children's conceptions of air pressure phenomena. Case studies of individuals have been constructed to explore the way conceptions change over time, and the difficulties presented by the concept of atmospheric pressure. These are used to evaluate different structural theories of conceptual change. The findings point to the complexity of children's conceptions, the stability and extension over time of productive conceptions, and the critical role of contextual features of phenomena in the conceptual change process. Although structural aspects of changes in concepts related to air pressure are identified, the difficulty of accessing the atmospheric pressure conception is argued to have more to do with presupposition based in perceptual features of air, and with difficulties associated with the application to particular phenomena. 相似文献
