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

Setting international benchmarks for education systems of the Organisation for Economic Co-operation and Development (OECD) countries is one of the goals of the OECD's Programme for International Student Assessment (PISA). However, some countries are not able to participate in PISA, despite their desire to set international benchmarks for their education systems. This article presents a method of setting international benchmarks for a country's school education system, without necessarily participating in PISA, by designing a test using the test items released by PISA for public consumption. The method has been implemented in a study that involved 1,500 Grade 10 students across 60 schools in Bhutan. The students were administered a mathematics test constructed from the PISA Mathematical Literacy test items. The study showed that the performance of Bhutanese students was comparable with the performance of the students from the countries that participated in PISA 2003 and that Bhutan could learn from both high- and low-performing school education systems of those countries. 相似文献

This paper reports on two inter-related studies that examined the use of non-traditional writing strategies within secondary school science classrooms. The first study involved Year 10 students who incorporated one letter writing experience into the learning sequence when studying genetics. The second study was with Year 9 students who used both a non-traditional laboratory writing heuristic and letter writing as part of the learning sequence when studying a topic on light. The same teacher was involved in both case studies. A higher-level analogy question was added to the teacher-prepared tests for each study to examine if students who participated in writing-to-learn activities were able to perform significantly better as a group than a group of students who completed traditional teacher directed laboratory activities and note-taking. Results indicate that for the first study there was not a significant difference using t-test analysis, while for the second study involving two writing treatments there was a statistically significant difference using t-test analysis. There was no statistically significant difference in responses between treatment and control groups when answering low level recall questions for either case study. Student interviews indicated awareness by students of the metacognitive value gained by using the non-traditional writing types. 相似文献

Examining the effect of multiple writing tasks on Year 10 biology students’ understandings of cell and molecular biology concepts 总被引：1，自引：0，他引：1
This paper reports on a study that examined the cumulative effects on students’ learning of science, and perceptions of the
role of writing in learning, when the students engaged in multiple writing tasks with planning strategy support. The study
was conducted with Year 10 biology students who completed two consecutive units on Cells and Molecular Biology. A mixed method
study was implemented using a pre-/post-test design with a focus on student performance on higher order conceptual questions,
and semi-structured interviews with treatment students after the completion of each unit of study. Results from the quantitative
component indicated that multiple, non-conventional writing had a significant benefit in helping students learn Molecular
Biology. The results for the Cell unit were not so conclusive suggesting the strategies are most useful for novel content.
The interviews with students demonstrated that they understood and engaged successfully with both the conceptual and linguistic
demands of the tasks. These findings, taken as a whole, confirm that multiple writing tasks can support effective student
learning, provided various pedagogical conditions are met. 相似文献

A theoretical framework for understanding applied learning processes is now warranted given the frequency with which these processes are now being utilised. Drawing in part from the literature on applied education in schools as well as theories of vocational learning such a framework is offered here that seeks to explain these learning processes in terms of the interplay of multiple accounts of influences at micro, meso and macro levels. This framework integrates current and emerging theories around practical learning, and provides insights into vocational and workplace education processes. We clarify how features of our framework complement broader current debates and concepts in the literature on vocational and work-related learning, particularly focusing on influences for that learning at the micro level of individuals’ experiences and understandings entailed in embodied cognition, or knowing through practice. Moreover, the value of this framework is demonstrated through its application to two very different case studies of learning processes in workplace settings. In conclusion, some implications for further theoretical and practical work in this area are advanced. 相似文献

There is growing research interest in the challenges and opportunities learners face in representing scientific understandings, processes and reasoning. These challenges include integrating verbal, visual and mathematical modes in science discourse to make strong conceptual links between representations and classroom experiences. Our paper reports on a project that aimed to identify practical and theoretical issues entailed in a representation-intensive approach to guiding students’ conceptual learning in science. We focus here on a teacher developing students’ understanding of the formation of ions and molecules. We argue that the representations produced by students in this process met the criteria for representational competence proposed by diSessa (Cognition and Instruction, 22, 293–331, 2004) and Kozma & Russell (2005). The students understood that an effective representation needed to show relevant information, focus on pertinent points, be self-sufficient in its claims about the topic and provide coherent links between different parts of the representation. The final activity showed that their representations reached Kozma & Russell’s (2005) highest level of competence, where the students were able to use specific features of their representations to critique their suitability for explaining bonding and were able to show how their representation linked to the periodic table as a representation. We conclude by considering the implications of these findings. 相似文献

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
