In science education, students sometimes create and engage in spontaneous science-oriented play where ideas about science and scientists are put to use. However, in previous research, little attention has been given to the role of informal spontaneous play in school science classrooms. We argue that, in order to enhance our understanding of learning processes in school science practices, research that investigates play as an aspect of everyday culture is needed. The aim of this paper is to explore students’ informal play as part of activity in lower secondary school science. The empirical study was conducted in two Swedish compulsory schools in grade 6. Data were collected throughout a teaching unit called ‘The Chemistry of Food’ during a 10-week period using video and audiotape recordings of classroom work. Our analyses show that the play students engage in involves the transformations of given tasks. We find that students’ spontaneous collective play offers opportunities for them to explore the epistemic values and norms of science and different ways of positioning in relation to science. Our findings contribute to the understanding of how learning in the school science classroom is socially and culturally–historically embedded and how individual students’ engagement through play may transform and transcend existing classroom practices. 相似文献

Comparing the epistemological underpinnings of students' and scientists' reasoning about conclusions
This study examined the criteria that middle school students, nonscientist adults, technicians, and scientists used to rate the validity of conclusions drawn by hypothetical students from a set of evidence. The groups' criteria for evaluating conclusions were considered to be dimensions of their epistemological frameworks regarding how knowledge claims are justified, and as such are integral to their scientific reasoning. Quantitative and qualitative analyses revealed that the responses of students and nonscientists differed from the responses of technicians and scientists, with the major difference being the groups' relative emphasis on criteria of empirical consistency or plausibility of the conclusions. We argue that the sources of the groups' differing epistemic criteria rest in their different spheres of cultural practice, and explore implications of this perspective for science teaching and learning. © 2001 John Wiley & Sons, Inc.

In many developed countries of the world, pupil attitudes to school science decline progressively across the age range of secondary schooling while fewer students are choosing to study science at higher levels and as a career. Responses to these developments have included proposals to reform the curriculum, pedagogy, and the nature of pupil discussion in science lessons. We support such changes but argue that far greater use needs to be made of out‐of‐school sites in the teaching of science. Such usage will result in a school science education that is more valid and more motivating. We present an “evolutionary model” of science teaching that looks at where learning and teaching take place, and draws together thinking about the history of science and developments in the nature of learning over the past 100 years or so. Our contention is that laboratory‐based school science teaching needs to be complemented by out‐of‐school science learning that draws on the actual world (e.g., through fieldtrips), the presented world (e.g., in science centres, botanic gardens, zoos and science museums), and the virtual worlds that are increasingly available through information technologies. 相似文献

The constructivist paradigm opens abundant opportunities for effective knowledge construction in which student build knowledge and continually evaluated and improved their knowledge. The teaching mode under constructivist pedagogy redefines the role of students and the teachers and their interrelationships by creating a nurturing environment. By adapting constructivist framework, this article demonstrates how the variation of learning practices was critical in facilitating Primary 4 students in Singapore to carry out seamless science learning. The variation of learning practices enables the students to explore a particular scientific concept through various learning experience across the contexts. The study adapted the framework of the Objects of Constructivist Learning Model for the improvement of the seamless science learning design. When redesigning the lesson, a conscious effort was made by the teacher to create relevant patterns of variation, that is, varying certain critical aspect(s) while keeping other aspects of the object of learning invariant in order to help students discern those critical aspects. The findings contribute knowledge to how the Theory of Variation can be used in analyzing seamless learning as well as designing for constructivist learning experiences. The findings have also demonstrated that the complementary practice of constructivist pedagogy with variation theory as a viable and effective approach in seamless science learning, at which it deepened students' understanding through constructing the critical aspects of a phenomenon. Engagement with primary school students in experiencing the variations allowed the translation of theory into practice. 相似文献

This study examined the role of computer-supported knowledge-building discourse and epistemic reflection in promoting elementary-school students’ scientific epistemology and science learning. The participants were 39 Grade 5 students who were collectively pursuing ideas and inquiry for knowledge advance using Knowledge Forum (KF) while studying a unit on electricity; they also reflected on the epistemic nature of their discourse. A comparison class of 22 students, taught by the same teacher, studied the same unit using the school’s established scientific investigation method. We hypothesised that engaging students in idea-driven and theory-building discourse, as well as scaffolding them to reflect on the epistemic nature of their discourse, would help them understand their own scientific collaborative discourse as a theory-building process, and therefore understand scientific inquiry as an idea-driven and theory-building process. As hypothesised, we found that students engaged in knowledge-building discourse and reflection outperformed comparison students in scientific epistemology and science learning, and that students’ understanding of collaborative discourse predicted their post-test scientific epistemology and science learning. To further understand the epistemic change process among knowledge-building students, we analysed their KF discourse to understand whether and how their epistemic practice had changed after epistemic reflection. The implications on ways of promoting epistemic change are discussed. 相似文献

Digital technologies have fast become integral within literacy learning and teaching across contexts as students engage with a variety of digital and multimodal texts. While teachers in New Zealand schools have a high degree of autonomy in the design and planning of literacy programs, little is currently known about how they understand and enact multiliteracies pedagogy (MLP). Using data gathered via interviews and classroom observations in an intermediate school in New Zealand, this article adopts a narrative inquiry approach to explore one teacher's approaches to using digital technologies and texts within literacy instruction. We explore in particular the ways in which MLP may be enacted implicitly rather than explicitly, within the complex matrix of teachers' personal beliefs and learning experiences, the perceived learning needs of students, and the school curriculum. We conclude with a call for the conscious and purposeful teaching of MLP, focusing on synaesthesia and the semiotic functions of texts. 相似文献

Mechanistic reasoning, or reasoning systematically through underlying factors and relationships that give rise to phenomena, is a powerful thinking strategy that allows one to explain and make predictions about phenomena. This article synthesizes and builds on existing frameworks to identify essential characteristics of students’ mechanistic reasoning across scientific content areas. We argue that these characteristics can be represented as epistemic heuristics, or ideas about how to direct one’s intellectual work, that implicitly guide mechanistic reasoning. We use this framework to characterize middle school students’ written explanatory accounts of two phenomena in different science content areas using these heuristics. We demonstrate evidence of heuristics in students’ accounts and show that the use of the heuristics was related to but distinct from science content knowledge. We describe how the heuristics allowed us to characterize and compare the mechanistic sophistication of account construction across science content areas. This framework captures elements of a crosscutting practical epistemology that may support students in directing the construction of mechanistic accounts across content areas over time, and it allows us to characterize that progress. 相似文献

This article reports the outcomes of a project in which teachers' sought to develop their ability to use instructional practices associated with argumentation in the teaching of science—in particular, the use of more dialogic approach based on small group work and the consideration of ideas, evidence, and argument. The project worked with four secondary school science departments over 2 years with the aim of developing a more dialogic approach to the teaching of science as a common instructional practice within the school. To achieve this goal, two lead teachers in each school worked to improve the use of argumentation as an instructional practice by embedding activities in the school science curriculum and to develop their colleague's expertise across the curriculum for 11‐ to 16‐year‐old students. This research sought to identify: (a) whether such an approach using minimal support and professional development could lead to measurable difference in student outcomes, and (b) what changes in teachers' practice were achieved (reported elsewhere). To assess the effects on student learning and engagement, data were collected of students' conceptual understanding, reasoning, and attitudes toward science from both the experimental schools and a comparison sample using a set of standard instruments. Results show that few significant changes were found in students compared to the comparison sample. In this article, we report the findings and discuss what we argue are salient implications for teacher professional development and teacher learning. © 2013 Wiley Periodicals, Inc.

During their years of schooling, students develop perceptions about learning and teaching, including the ways in which teachers
impact on their learning experiences. This paper presents student perceptions of teacher pedagogy as interpreted from a study
focusing on students' experience of Year 7 science. A single science class of 11 to 12 year old students and their teacher
were monitored for the whole school year, employing participant observation, and interviews with focus groups of students,
their teacher and other key members of the school. Analysis focused on how students perceived the role of the teacher's pedagogy
in constructing a learning environment that they considered conducive to engagement with science learning. Two areas of the
teacher's pedagogy are explored from the student perspective of how these affect their learning: instructional pedagogy and
relational pedagogy. Instructional pedagogy captures the way the instructional dialogue developed by the teacher drew the students into the learning process and enabled
them to “understand” science. How the teacher developed a relationship with the students is captured as relational pedagogy, where students said that they learned better when teachers were passionate in their approach to teaching, provided a supportive
learning environment and made them feel comfortable. The ways in which the findings support the direction for the middle years
and science education are considered. 相似文献

What are the barriers to technology‐rich inquiry pedagogy in urban science classrooms, and what kinds of programs and support structures allow these barriers to be overcome? Research on the pedagogical practices within urban classrooms suggests that as a result of many constraints, many urban teachers' practices emphasize directive, controlling teaching, that is, the “pedagogy of poverty” (Haberman, 1991 ), rather than the facilitation of students' ownership and control over their learning, as advocated in inquiry science. On balance, research programs that advocate standards‐based or inquiry teaching pedagogies demonstrate strong learning outcomes by urban students. This study tracked classroom research on a technology‐rich inquiry weather program with six urban science teachers. The teachers implemented this program in coordination with a district‐wide middle school science reform. Results indicated that despite many challenges in the first year of implementation, students in all 19 classrooms of this program demonstrated significant content and inquiry gains. In addition, case study data comprised of twice‐weekly classroom observations and interviews with the six teachers suggest support structures that were both conducive and challenging to inquiry pedagogy. Our work has extended previous studies on urban science pedagogy and practices as it has begun to articulate what role the technological component plays either in contributing to the challenges we experienced or in helping urban science classrooms to realize inquiry science and other positive learning values. Although these data outline results after only the first year of systemic reform, we suggest that they begin to build evidence for the role of technology‐rich inquiry programs in combating the pedagogy of poverty in urban science classrooms. © 2002 John Wiley & Sons, Inc.

In the first part of the article I present an epistemological critique of forms of pedagogy founded on Piagetian constructivism. Despite the appeal of the notion that learners construct their understanding, I argue that constructivism is problematic because it ignores the subjectivity of the learner and the socially and historically situated nature of knowing; it denies the essentially collaborative and social nature of meaning making; and it privileges only one form of knowledge, namely, the technical rational. I then present a critique of active learning and student-centered forms of pedagogy. I argue that in our models of teaching we rely on too many unexamined assumptions from developmental psychology and we take for granted the problematic notion that children learn by doing. My central thesis is that constructivism is flawed because of its inability to come to grips with the essential issues of culture, power, and discourse in the classroom. In the concluding section of the article I present a preliminary account of a sociocultural approach to teaching and learning that takes seriously the notion that learning is situated in contexts, that students bring their own subjectivities and cultural perspectives to bear in constructing understanding, that issues of power exist in the classroom that need to be addressed, and that education into scientific ways of knowing requires understanding modes of classroom discourse and enabling students to negotiate these modes effectively so that they may master and critique scientific ways of knowing without, in the process, sacrificing their own personally and culturally constructed ways of knowing. 相似文献

This paper is concerned with the process of how subject and pedagogic knowledge emerge through teachers' learning in science. It suggests that problematizing subject knowledge through direct experience of learning in science, particularly in those areas that are known to be difficult, constitutes a productive way of turning a deficit model of teacher subject knowledge into a positive experience with considerable potential for the development of pedagogy. The paper draws on exemplification of student learning to contextualize the discussion within current debate in science education concerned with conceptual change and metacognition. It is argued that the act of addressing what are problematic science concepts in their own learning, affords an opportunity for students to focus on the nature of the concepts being explored and how understanding of them might be developed. It is implied that a notion of ‘learning practice’ in university taught sessions, in addition to the embedded model of generating pedagogic insight through teaching experience in school placements, would constitute a productive mechanism for the synthesis of subject and pedagogic knowledge. 相似文献

When students collaboratively design and build artifacts that require relevant understanding and application of science, many aspects of scientific literacy are developed. Design-based inquiry (DBI) is one such pedagogy that can serve these desired goals of science education well. Focusing on a Projectile Science curriculum previously found to be implemented with satisfactory fidelity, we investigate the many hidden challenges when using DBI with Grade 8 students from one school in Singapore. A case study method was used to analyze video recordings of DBI lessons conducted over 10 weeks, project presentations, and interviews to ascertain the opportunities for developing scientific literacy among participants. One critical factor that hindered learning was task selection by teachers, which emphasized generic scientific process skills over more important cognitive and epistemic learning goals. Teachers and students were also jointly engaged in forms of inquiry that underscored artifact completion over deeper conceptual and epistemic understanding of science. Our research surfaced two other confounding factors that undermined the curriculum; unanticipated teacher effects and the underestimation of the complexity of DBI and of inquiry science in general. Thus, even though motivated or experienced teachers can implement an inquiry science curriculum with good fidelity and enjoy school-wide support, these by themselves will not guarantee deep learning of scientific literacy in DBI. Recommendations are made for navigating the hands- and minds-on aspects of learning science that is an asset as well as inherent danger during DBI teaching. 相似文献

The purpose of this study was to develop and validate an online contextualized test for assessing students’ understanding of epistemic knowledge of science. In addition, how students’ understanding of epistemic knowledge of science interacts with learner factors, including time spent on science learning, interest, self-efficacy, and gender, was also explored. The participants were 489 senior high school students (244 males and 245 females) from eight different schools in Taiwan. Based on the result of an extensive literature review, we first identified six factors of epistemic knowledge of science, such as status of scientific knowledge, the nature of scientific enterprise, measurement in science, and so on. An online test was then created for assessing students’ understanding of the epistemic knowledge of science. Also, a learner-factor survey was developed by adopting previous PISA survey items to measure the abovementioned learner factors. The results of this study show that; (1) by factor analysis, the six factors of epistemic knowledge of science could be grouped into two dimensions which reflect the nature of scientific knowledge and knowing in science, respectively; (2) there was a gender difference in the participants’ understanding of the epistemic knowledge of science; and (3) students’ interest in science learning and the time spent on science learning were positively correlated to their understanding of the epistemic knowledge of science. 相似文献

We describe the implementation of a specially designed teaching innovation, embedded in the context of energy, for the promotion of specific aspects of the nature of science (NOS). We present empirical results from the implementation of the teaching and learning materials in three intact sixth-grade classes that involved a total of 64 students. We report on students' learning gains and we discuss the ensuing implications for teaching and learning with an emphasis on epistemic ideas. The integration of activities promoting understandings of energy and specific aspects of the NOS seems to work well in impacting on students' epistemic awareness. The findings reveal interesting aspects about the interplay between understandings of energy and the NOS. The article also illustrates that it is possible to teach productively specific aspects of a consensus view of the NOS from a fairly young age without having to rely on advanced science knowledge or explore the intricacies and differentiations across science disciplines. 相似文献

The purpose of this study was to compare the associations of epistemic beliefs in science, performance of scientific reasoning in university students from Taiwan and India, and the relations with their science learning experiences. A total of 126 university students including 67 from Taiwan and 59 from India who had science and mathematics backgrounds were involved in the study. Students’ epistemic beliefs in science were assessed by the SEV questionnaire, while their reasoning performance and learning experiences were prompted by open-ended questions and survey items. Content analysis was performed to analyze their scientific reasoning, and correlation analysis, t tests and ANOVA were applied to reveal the associations between variables. The results showed that students from both countries differed in epistemic beliefs in the dimensions of certainty, development and justification. While few students from either country performed successfully in identifying genuine evidence and giving full rebuttals, Taiwanese participants seemed to demonstrate slightly better scientific reasoning. It was found that the Indian students were more balanced in receiving structured and engaged learning experiences. Varying associations for the students from the different countries were found between epistemic beliefs and scientific reasoning performance, and between epistemic beliefs and science learning experiences. 相似文献

This study presents the cases of two teachers in a Jewish supplementary school whose experiences as learners in a year-long professional development (PD) program shaped their teaching practice. The PD program, based in a theory of havruta text learning, immersed the faculty in the very pedagogy they were being encouraged to use in their teaching and gave them tools to enact it to meet their classroom learning goals. In one case, the teacher learned to share “control” and give students a direct encounter with biblical texts; in another case, the teacher supported students to engage in interpretive play with the text. This study demonstrates the potential of the pedagogy of havruta learning to harness the religious educator's role as both learner and teacher and how the continuity between these roles can affect teaching practice in multiple ways. 相似文献
