This paper describes a qualitative study that investigated the nature of the participation structures and how the participation structures were organized by four science teachers when they constructed and communicated science content in their classrooms with computer technology. Participation structures focus on the activity structures and processes in social settings like classrooms thereby providing glimpses into the complex dynamics of teacher–students interactions, configurations, and conventions during collective meaning making and knowledge creation. Data included observations, interviews, and focus group interviews. Analysis revealed that the dominant participation structure evident within participants’ instruction with computer technology was (Teacher) initiation–(Student and Teacher) response sequences–(Teacher) evaluate participation structure. Three key events characterized the how participants organized this participation structure in their classrooms: setting the stage for interactive instruction, the joint activity, and maintaining accountability. Implications include the following: (1) teacher educators need to tap into the knowledge base that underscores science teachers’ learning to teach philosophies when computer technology is used in instruction. (2) Teacher educators need to emphasize the essential idea that learning and cognition is not situated within the computer technology but within the pedagogical practices, specifically the participation structures. (3) The pedagogical practices developed with the integration or with the use of computer technology underscored by the teachers’ own knowledge of classroom contexts and curriculum needs to be the focus for how students learn science content with computer technology instead of just focusing on how computer technology solely supports students learning of science content.  相似文献

We all know that they do it, but what do students laugh about when learning science together? Although research has shown that students do use humor when they learn science, the role of humor in science education has received little attention. In this study, undergraduate students’ laughter during collaborative work in physics has been investigated. In order to do this, a framework inspired by conversation analysis has been used. Empirical data was drawn from two video-recorded sessions in which first-year engineering students solved physics problems together. The analysis revealed that the students’ use of humor was almost exclusively related to physics. Five themes identified summarize the role of humor in the group discussions: Something is obvious, Something is difficult, Something said might be wrong, Something is absurd, and Something said is not within informal norms.This study shows that humor may contribute not only to a good working atmosphere and thereby to the students’ learning but also how humor interrelates with both disciplinary culture of physics and its epistemology. The students do not only create and re-create humor that facilitates their social interactions, but through humor they constitute local norms of science and engage with the disciplinary discourse.  相似文献

Because of ever stricter standards of accountability, science teachers are under an increasing and unrelenting pressure to demonstrate the effects of their teaching on student learning. Econometric perspectives of teacher quality have become normative in assessment of teachers’ work for accountability purposes. These perspectives seek to normalize some key ontological assumptions about teachers and teaching, and thus play an important role in shaping our understanding of the work science teachers do as teachers in their classrooms. In this conceptual paper I examine the ontology of science teaching as embedded in econometric perspectives of teacher quality. Based on Foucault’s articulation of neoliberalism as a discourse of governmentality in his ‘The Birth of Biopolitics’ lectures, I suggest that this ontology corresponds well with the strong and substantivist ontology of work under neoliberalism, and thus could potentially be seen as reflection of the influence of neoliberal ideas in education. Implications of the mainstreaming of an ontology of teaching that is compatible with neoliberalism can be seen in increasing marketization of teaching, ‘teaching evangelism’, and impoverished notions of learning and teaching. A shift of focus from teacher quality to quality of teaching and building conceptual models of teaching based on relational ontologies deserve to be explored as important steps in preserving critical and socially just conceptions of science teaching in neoliberal times.  相似文献

This study explored how elementary teachers leveraged and structured student-involved formative assessment to promote metacognition and self-regulation. Research has suggested a connection between formative assessment practices (e.g., self-assessment and peer-assessment) and metacognition. However, this connection has limited empirical support, especially within early elementary contexts (i.e. Grades K-4). In this study, 44 Ontario elementary teachers completed a survey reporting their teaching and assessment practices and beliefs about metacognition. Five participants were then purposefully selected for semi-structured interviews to describe their experiences developing students’ metacognition and self-regulatory capabilities through student-involved assessment processes. Data were inductively and thematically analysed. Participants emphasized the value of assessment as learning practices (e.g., self-assessment and reflective thinking) to develop students’ metacognition and discussed the need for ongoing student feedback regarding metacognitive strategies. However, despite purposefully implementing formative assessment to enhance metacognition and self-regulation, participants articulated the need for additional resources to support the cultural shift towards assessment for and as learning within their classrooms.  相似文献

Team teaching is becoming more common in undergraduate programmes of study although the relative merits to the more traditional individually taught courses have not been determined for best practice. For this study, 15 final-year undergraduate computer science students were interviewed to gain insight into their learning experiences. A thematic analysis of the interview data identified the perceived advantages and disadvantages of each mode of teaching. The advantages of individually taught courses included: consistency of content delivery and advice, familiarity with the lecturer’s teaching style and better continuity of the subject content. The disadvantage of individually taught modules included missing knowledge, compared to a team approach. Advantages of team-taught modules included: greater insight into a topic delivered by multiple team members. Disadvantages included: content overlap, conflicting messages relating to assessment, team members not taking ownership of their roles and responsibilities and a belief that overall team failure is worse than individual failure to deliver a module well. The results revealed that individually taught modules were generally preferred to team-taught modules. A set of best practice recommendations are proposed to address the challenges when delivering team-taught teaching and become more student focused.  相似文献

This paper focuses on the curriculum links between statistics and science that teachers need to understand and apply in order to be effective teachers of the two fields of study. Meaningful statistics does not exist without context and science is the context for this paper. Although curriculum documents differ from country to country, this paper uses extracts from three countries: Australia, New Zealand and the USA. The statistical ideas from the Australian Curriculum: Mathematics, the New Zealand Mathematics and Statistics Curriculum and the US Common Core State Standards for Mathematics are linked to the relevant parts of the Australian Curriculum: Science, the New Zealand Science Curriculum and the US Next Generation Science Standards for States, by States. Teachers of mathematics need to be aware of the potential of science to provide meaningful contexts within which to set statistical investigations. Similarly, teachers of science, who are developing methods for implementing investigations and experiments in their classrooms, need to be aware of the close ties to statistical tools for decision-making.  相似文献

A study is presented that explores how students’ knowledge structures, as related to the scientific method, compare at different student ages. A word association test comprised of ten total stimulus words, among them experiment, science fair, and hypothesis, is used to probe the students’ knowledge structures. Students from grades four, five, and eight, as well as first-year college students were tested to reveal their knowledge structures relating to the scientific method. Younger students were found to have a naïve view of the science process with little understanding of how science relates to the real world. However, students’ conceptions about the scientific process appear to be malleable, with science fairs a potentially strong influencer. The strength of associations between words is observed to change from grade to grade, with younger students placing science fair near the center of their knowledge structure regarding the scientific method, whereas older students conceptualize the scientific method around experiment.  相似文献

The purpose of this study was, first, to understand the item hierarchy regarding students’ understanding of scientific models and modeling (USM). Secondly, this study investigated Taiwanese students’ USM progression from 7th to 12th grade, and after participating in a model-based curriculum. The questionnaire items were developed based on 6 aspects of USM, namely, model type, model content, constructed nature of models, multiple models, change of models, and purpose of models. Moreover, 10 representations of models were included for surveying what a model is. Results show that the purpose of models and model type items covered a wide range of item difficulties. At the one end, items for the purpose of models are most likely to be endorsed by the students, except for the item “models are used to predict.” At the other end, the “model type” items tended to be difficult. The students were least likely to agree that models can be text, mathematical, or dynamic. The items of the constructed nature of models were consistently located above the average, while the change of models items were consistently located around the mean level of difficulty. In terms of the natural progression of USM, the results show significant differences between 7th grade and all grades above 10th, and between 8th grade and 12th grade. The students in the 7th grade intervention group performed better than the students in the 7th and 8th grades who received no special instruction on models.  相似文献

Measuring gifted and talented (GT) students’ perceptions of their GT label might seem to be a relatively straightforward affair. Most of this research uses survey methods that ask GT students to complete Likert scale or open-ended response questionnaires about their perceptions of the label and then presents results in clear and quantifiable terms, such as “X % of students hold positive perceptions of the GT label.” However, our qualitative study of GT students in two middle school social studies classrooms presents findings that not only trouble, but prompt questions about simple proclamations regarding GT students’ perceptions of the GT label. What we found was that given the opportunity to share their thoughts at length, this group of GT students expressed a range of often contradictory perceptions about their GT label. Students expressed multiple interpretations and perceptions of the GT label, as well as both embraced the label and rejected the label.  相似文献

The inclusion of the practice of “developing and using models” in the Framework for K-12 Science Education and in the Next Generation Science Standards provides an opportunity for educators to examine the role this practice plays in science and how it can be leveraged in a science classroom. Drawing on conceptions of models in the philosophy of science, we bring forward an agent-based account of models and discuss the implications of this view for enacting modeling in science classrooms. Models, according to this account, can only be understood with respect to the aims and intentions of a cognitive agent (models for), not solely in terms of how they represent phenomena in the world (models of). We present this contrast as a heuristic—models of versus models for—that can be used to help educators notice and interpret how models are positioned in standards, curriculum, and classrooms.  相似文献

The aim of this study was to examine the potential impact of the representational characteristics of models and students’ educational levels on students’ views of scientific models and modeling (VSMM). An online multimedia questionnaire was designed to address three major aspects of VSMM, namely the nature of models, the nature of modeling, and the purpose of models. The three scales of representational characteristics included modality, dimensionality, and dynamics. A total of 102 eighth graders and 87 eleventh graders were surveyed. Both quantitative data and written responses were analyzed. The influence of the representational characteristics seemed to be more salient on the nature of models and the purpose of models. Some interactions between the educational levels and the representational characteristics showed that the high school students were more likely to recognize textual representations and pictorial representations as models, while also being more likely to appreciate the differences between 2D and 3D models. However, some other differences between educational levels did not necessarily suggest that the high school students attained more sophisticated VSMM. For instance, in considering what information should be included in a model, students’ attention to particular affordances of the representation can lead to a more naive view of modeling. Implications for developing future questionnaires and for teaching modeling are suggested in this study.  相似文献

Elementary teachers in the United States are tasked with teaching all core subject matter and have training that involves many topics, which may limit the depth of their subject matter knowledge. Since they have low content knowledge, they often feel less confident about teaching technical subject matter, such as science (Bleicher Journal of Science Teacher Education 17:165–187, 2006). The problem of low confidence of elementary teachers for science instruction is exacerbated when they are expected to teach science using inquiry (Hanuscin et al. Science Education 95:145–167, 2010). Self-regulated learning microanalysis, which supports both instruction and assessment, can help teachers reflect on their learning processes. This technique may provide clues for teachers to improve strategies for learning and give information to professional development instructors to inform teacher professional development experiences. The purpose of this study was to examine self-regulatory learning cycles that fourteen elementary teachers experienced while engaged in learning about inquiry during a professional development. Results of this study showed that before the professional development, teachers reported low self-efficacy but high task value and perceived instrumentality for learning about inquiry. As the professional development progressed, teachers improved their goal setting skills, self-monitoring performance, and learning tactics. The self-regulated learning microanalysis revealed information not communicated in the professional development experience, which led to adaptation of the activities in real-time to meet the needs indicated on the self-regulated learning microanalysis reports. Measuring teacher learning processes allowed the professional development instructors to pinpoint difficulties and successes during the learning tasks, which aided in precise adaptation of experiences for teacher needs.  相似文献

It has become increasingly recognized that what teachers and students value affect teaching and learning in general and in the area of mathematics in particular. Yet, the extent to which this is so varies across cultural regions. In recent years, how the ethnic Chinese teach and learn mathematics has attracted much attention worldwide. It is precisely the purpose of the present study to investigate the value structures of three Chinese regions. Using a recently developed and validated questionnaire, students’ values in mathematics learning in the Chinese Mainland, Hong Kong and Taiwan are delineated. In the first place, the results reveal that there are six dimensions in the students’ value structure, namely achievement, relevance, practice, communication, information and communications technology as well as feedback. However, in each of the six value components derived from the principal components analysis, statistically significant differences between the regions were found.  相似文献

Wicked sustainability problems (WSPs) are an important and particularly challenging type of problem. Science and engineering education can play an important role in preparing students to deal with such problems, but current educational practice may not adequately prepare students to do so. We address this gap by providing insights related to students’ abilities to address WSPs. Specifically, we aim to (I) describe key constituents of engineering students’ approaches to a WSP, (II) evaluate these approaches in relation to the normative context of education for sustainable development (ESD), and (III) identify relevant aspects of learning related to WSPs. Aim I is addressed through a phenomenographic study, while aims II and III are addressed by relating the results to research literature about human problem solving, sustainable development, and ESD. We describe four qualitatively different ways of approaching a specific WSP, as the outcome of the phenomenographic study: A. Simplify and avoid, B. Divide and control, C. Isolate and succumb, and D. Integrate and balance. We identify approach D as the most appropriate approach in the context of ESD, while A and C are not. On this basis, we identify three learning objectives related to students’ abilities to address WSPs: learn to use a fully integrative approach, distinguish WSPs from tame and well-structured problems, and understand and consider the normative context of SD. Finally, we provide recommendations for how these learning objectives can be used to guide the design of science and engineering educational activities.  相似文献

Reading the interesting article Discerning selective traditions in science education by Per Sund, which is published in this issue of CSSE, allows us to open the discussion on procedures for teaching science today. Clearly there is overlap between the teaching of science and other areas of knowledge. However, we must constantly develop new methods to teach and differentiate between science education and teaching science in response to the changing needs of our students, and we must analyze what role teachers and teacher educators play in both. We must continually examine the methods and concepts involved in developing pedagogical content knowledge in science teachers. Otherwise, the possibility that these routines, based on subjective traditions, prevent emerging processes of educational innovation. Modern science is an enormous field of knowledge in its own right, which is made more expansive when examined within the context of its place in society. We propose the need to design educative interactions around situations that involve science and society. Science education must provide students with all four dimensions of the cognitive process: factual knowledge, conceptual knowledge, procedural knowledge, and metacognitive knowledge. We can observe in classrooms at all levels of education that students understand the concepts better when they have the opportunity to apply the scientific knowledge in a personally relevant way. When students find value in practical exercises and they are provided opportunities to reinterpret their experiences, greater learning gains are achieved. In this sense, a key aspect of educational innovation is the change in teaching methodology. We need new tools to respond to new problems. A shift in teacher education is needed to realize the rewards of situating science questions in a societal context and opening classroom doors to active methodologies in science education to promote meaningful learning through meaningful teaching.  相似文献
