A growing body of research argues that teachers’ beliefs and practices should be studied within the sociocultural contexts of their work because the relationship between their beliefs and practices is both complex and context-dependent. There is a need for further research in this area in understudied contexts such as developing countries, in order to promote effective education in schools and the professional development of teachers. This paper argues that if this ‘black box’ of sociocultural contexts in which science teachers are embedded is better understood, it may be possible to identify specific aspects of these contexts related to educational organizations that act as either supports or barriers to pedagogical reform or to implementing innovations in science education. Consequently, the main purpose of this study is to explore the sociocultural contexts of ten Egyptian science teachers and to what extent these sociocultural contexts help in understanding teachers’ pedagogical beliefs and practices. This paper, by utilizing a multi-grounded theory approach and qualitative methods, reveals a variety of sociocultural contexts that are related to teachers’ pedagogical beliefs and practices. 相似文献

This study is an attempt to gain new insight, on behalf of science teachers, into the integration of metacognition (MC) into science education. Participants were 44 elementary school science teachers attending an in-service teacher-training (INST) program. Data collection was carried out by several data sources: recordings of all verbal discussions that took place during the program, teachers’ written reflections, and semi-structured individual interviews. Our study provides a qualitative analysis of the 44 teachers’ voices as a group, as well as a detailed case-study narrative analysis of three teachers’ stories The findings show that the teachers’ intuitive (pre-instructional) thinking was incomplete and unsatisfactory and their voices were skeptical and against the integration of MC. After teachers had mastered the notion of MC in the INST program, the following outcomes have been identified: (a) teachers expressed amazement at how such an important and relevant issue had been almost invisible to them; (b) teachers identified the affective character of metacognitive experiences as the most significant facet of MC, which acts as a mediator between teaching and learning; (c) the complete lack of learning materials addressing MC and the absence of supportive in-classroom guidance were identified as the major obstacles for its implementation; (d) teachers expressed a willingness to continue their professional development toward expanding their abilities to integrate MC as an inseparable component of the science curriculum. The implications of the findings for professional development courses in the field of MC are discussed. 相似文献

Primary pre-service teachers (PSTs) in Australia often have low confidence and negative experiences in relation to science and teaching science. This paper reports on pre-post survey data produced by four institutions involved in a multi-institutional project exploring the use of university-school partnerships for primary science teacher education. The findings show that the experience of engagement in school-based science teaching contributed to the development PST classroom readiness particularly with respect to statistically significant increases in confidence. We argue that moving tutorials from university into schools supports PSTs’ engagement with the teaching profession and teaching science. 相似文献

Inquiry- and context-based teaching strategies have been proven to stimulate and motivate students’ interests in learning science. In this study, 12 teachers reflected on these strategies after using them in primary schools. The teachers participated in a continuous professional development (CPD) programme. During the programme, they were also introduced to a teaching model from a European project, where inquiry- and context-based education (IC-BaSE) strategies were fused. The research question related to teachers’ reflections on these teaching strategies, and whether they found the model to be useful in primary schools after testing it with their students. Data collection was performed during the CPD programme and consisted of audio-recorded group discussions, individual portfolios and field notes collected by researchers. Results showed that compared with using only one instructional strategy, teachers found the new teaching model to be a useful complement. However, their discussions also showed that they did not reflect on choices of strategies or purposes and aims relating to students’ understanding, or the content to be taught. Before the CPD programme, teachers discussed the use of inquiry mainly from the aspect that students enjoy practical work. After the programme, they identified additional reasons for using inquiry and discussed the importance of knowing why inquiry is performed. However, to develop teachers’ knowledge of instructional strategies as well as purposes for using certain strategies, there is need for further investigations among primary school teachers. 相似文献

Analogies can play a relevant role in students’ learning. However, for the effective use of analogies, teachers should not only have a well-prepared repertoire of validated analogies, which could serve as bridges between the students’ prior knowledge and the scientific knowledge they desire them to understand, but also know how to introduce analogies in their lessons. Both aspects have been discussed in the literature in the last few decades. However, almost nothing is known about how teachers draw their own analogies for instructional purposes or, in other words, about how they reason analogically when planning and conducting teaching. This is the focus of this paper. Six secondary teachers were individually interviewed; the aim was to characterize how they perform each of the analogical reasoning subprocesses, as well as to identify their views on analogies and their use in science teaching. The results were analyzed by considering elements of both theories about analogical reasoning: the structural mapping proposed by Gentner and the analogical mechanism described by Vosniadou. A comprehensive discussion of our results makes it evident that teachers’ content knowledge on scientific topics and on analogies as well as their pedagogical content knowledge on the use of analogies influence all their analogical reasoning subprocesses. Our results also point to the need for improving teachers’ knowledge about analogies and their ability to perform analogical reasoning. 相似文献

In case studies of two first-year elementary classroom teachers, we explored the influence of informal science education (ISE) they experienced in their teacher education program. Our theoretical lens was identity development, delimited to classroom science teaching. We used complementary data collection methods and analysis, including interviews, electronic communications, and drawing prompts. We found that our two participants referenced as important the ISE experiences in their development of classroom science identities that included resilience, excitement and engagement in science teaching and learning–qualities that are emphasized in ISE contexts. The data support our conclusion that the ISE experiences proved especially memorable to teacher education interns during the implementation of the No Child Left Behind policy which concentrated on school-tested subjects other than science. 相似文献

The impacts of biotechnology are found in nearly all sectors of society from health care and food products to environmental issues and energy sources. Despite the significance of biotechnology within the sciences, it has not become a prominent trend in science education. In this study, we seek to more fully identify biology teachers’ concerns about biotechnology instruction and their reported practices. Consistent with the Stages of Concern framework as modified by Hord et al., we investigated teachers’ awareness, informational, personal, management, consequences, collaboration, and refocusing concerns about biotechnology teaching by employing a qualitative design that allowed for the emergence of teachers’ ideas. Twenty high school life science teachers attending a biotechnology institute were interviewed using an interview protocol specifically designed to target various Stages of Concern. Although the Stages of Concern framework guided the development of interview questions in order to target a wide range of concerns, data analysis employed a grounded theory approach wherein patterns emerged from teachers’ own words and were constantly compared with each other to generate larger themes. Our results have potential to provide guidance for professional development providers and curriculum developers committed to supporting initial implementation of biotechnology education. Recommendations include supporting teacher development of biotechnology content knowledge; promoting strategies for obtaining, storing and managing biotechnology equipment and materials; providing opportunities for peer teaching as a means of building teacher confidence; and highlighting career opportunities in biotechnology and the intersections of biotechnology and everyday life. 相似文献

This paper describes Spanish science teachers’ thinking about issues concerning the nature of science (NOS) and the relationships connecting science, technology, and society (STS). The sample consisted of 774 in-service and pre-service teachers. The participants responded to a selection of items from the Questionnaire of Opinions on Science, Technology & Society in a multiple response model. These data were processed to generate the invariant indices that are used as the bases for subsequent quantitative and qualitative analyses. The overall results reflect moderately informed conceptions, and a detailed analysis by items, categories, and positions reveals a range of positive and negative conceptions about the topics of NOS dealt with in the questionnaire items. The implications of the findings for teaching and teacher training on the themes of NOS are discussed. 相似文献

Reforms are typically criticized for failing to bridge the gap between practitioners and researchers and for the lack of research support provided prior to implementation. Research has indicated that preservice teachers’ understandings of high-quality science teaching are formed by teacher training programs. The purposes of this study are to investigate views about science in preservice teachers in old and new teacher training programs and to determine whether and how these two programs shape teacher trainees’ views of science. A total of 459 students from a 4-year elementary science teacher training program participated in the study. A 41-item instrument was used to collect data. Four factors were extracted from the data, explaining 41.58% of the variance, and the reliability was found to be .86. There were significant differences for both males and females between the old and new programs. However, no difference was found between males’ and females’ total scores. In addition, students from the two programs had significantly different scores on the sub-scales of “Anxiety” and “Uncertainty”. For example, males in the new program had significantly higher scores on the “Anxiety” and “Uncertainty” sub-scales. The overall increase in science course hours and decrease in science method course hours in the new program may account for these findings. 相似文献

The study reported here investigated experienced teachers’ views on several nature of science (NOS) issues 2 to 5 years after they completed a demanding secondary science teacher education program in which the NOS was an extensive and recurring component. Both quantitative and qualitative data were collected and analyzed to determine study participants’ NOS understanding. Study participant’s NOS views were determined to be generally accurate and robust, suggesting that experiences in their science teacher education program had a long-lasting positive impact on NOS understanding. The preservice program that study participants completed has several unique features that may account for that long-lasting impact and has implications for preservice and inservice science teacher education professional development. 相似文献

Teacher education programs across North America are transforming. What were once piecemeal programs consisting of often unrelated courses are now becoming coherent and intertwined trajectories toward teacher certification. Part of this transformation can be attributed to the weaving of “signature pedagogies” throughout overarching program frameworks. A modern signature pedagogy within science teacher education is the integration of technology with science area content and effective pedagogy. In this article the author reports an action research study aimed toward promoting the “scholarship of teaching” of pre-service teachers through articulating changes in their maturing perceptions of the integrated relationship between technological, pedagogical, and science content knowledge. 相似文献

Teachers need an understanding of the nature of science (NOS) to enable them to incorporate NOS into their teaching of science. The current study examines the usefulness of a strategy for challenging or changing teachers’ understandings of NOS. The teachers who participated in this study were 10 initial teacher education chemistry students and six experienced teachers from secondary and primary schools who were introduced to an explicit and reflective activity, a dramatic reading about a historical scientific development. Concept maps were used before and after the activity to assess teachers’ knowledge of NOS. The participants also took part in a focus group interview to establish whether they perceived the activity as useful in developing their own understanding of NOS. Initial analysis led us to ask another group, comprising seven initial teacher education chemistry students, to take part in a modified study. These participants not only completed the same tasks as the previous participants but also completed a written reflection commenting on whether the activity and focus group discussion enhanced their understanding of NOS. Both Lederman et al.’s (Journal of Research in Science Teaching, 39(6), 497–521, 2002) concepts of NOS and notions of “naive” and “informed” understandings of NOS and Hay’s (Studies in Higher Education, 32(1), 39–57, 2007) notions of “surface” and “deep” learning were used as frameworks to examine the participants’ specific understandings of NOS and the depth of their learning. The ways in which participants’ understandings of NOS were broadened or changed by taking part in the dramatic reading are presented. The impact of the data-gathering tools on the participants’ professional learning is also discussed. 相似文献
