We have designed a model for transformational science teaching focused on linking theory and practice through curriculum decision making that has been the framework for professional development sessions for middle-grade science teachers during the past 5 years. Interviews with teachers revealed that their experiences with curriculum development were of significant value in making decisions concerning the design of classroom environments. As teachers reflected on current research about teaching and learning, in collaboration with university scientists and science educators, they were informed by theoretical perspectives which held implications for their practice. Curriculum development became a vehicle for professional development and school reform; however, it was vital that the teachers were in clear communication with their administrators and communities concerning reform issues. Students and teachers from schools implementing the model and from control sites were interviewed to determine the model's influence on instructional practices and student attitude and achievement in science. The five-phase model for transformational science teaching is discussed here, accompanied by teacher comments about tensions experienced at each phase. This discussion is followed by an analysis of teacher and student interview data that reveals teachers' use of instructional strategies and students' attitudes toward science. Results and analysis of student performance on a mandated end-of-grade science test are also included. From this evidence, we recommend a new design for professional development opportunities for teachers that engages them in decision making as they reflect about the connections between theory and practice and the value of continually testing, revising, and reevaluating curriculum and instructional issues.

An examination of the professional lives of women science teachers presents an opportunity to consider ways in which women became ‘knowledge purveyors’ and to reflect on the extent to which they challenged contemporary boundaries about what science women should know. An analysis of the life of a woman science teacher who was also a ‘professed’ religious illuminates the complexity of a professional life shaped by an overlay of vocation and employment. Mother Bernard Towers's teaching life extended over the greater part of the twentieth century. As a science teacher she was influenced by changing understandings of the gendered science curriculum and the cultural and religious environment in which she lived. At the same time she challenged contemporary constraints on the teaching of science to girls, helped her pupils gain access to high‐status ‘hard’ science options and expanded the kinds of science that they could expect to know. 相似文献

This study, conducted from a constructivist perspective, examined the belief system of a prospective elementary teacher (Barbara) about science teaching and learning as she developed professional knowledge within the context of reflective science teacher education. From an analysis of interviews, observation, and written documents, I constructed a profile of Barbara's beliefs that consisted of three foundational and three dualistic beliefs. Her foundational beliefs concerned (a) the value of science and science teaching, (b) the nature of scientific concepts and goals of science instruction, and (c) control in the science classroom. Barbara held dualistic beliefs about (a) how children learn science, (b) the science students' role, and (c) the science teacher's role. Her dualistic beliefs formed two contradictory nests of beliefs. One nest, grounded in lifelong science learner experiences, reflected a didactic teaching orientation and predominantly guided her practice. The second nest, not well grounded in experience, embraced a hands‐on approach and predominantly guided her vision of practice. The findings accentuate the complexity and nestedness of teachers' belief systems and underscore the significance of identifying prospective teachers' beliefs, espoused and enacted, for designing teacher preparation programs. © 2003 Wiley Periodicals, Inc.

This study examines Turkish pre-service science teachers' understanding of science concepts and their confidence in its teaching. A total of 299 senior science education major students participated in the study. Data collection instruments included the Science Concepts Test, and the Science Teaching Efficacy Belief Instrument. Although findings of the study indicated that majority of the participants held misconceptions concerning fundamental science concepts, they generally felt confident about teaching it. The relationship that might exist among pre-service science teachers' confidence in their effectiveness in teaching and the number of the science courses completed in university is examined. 相似文献

Since science became part of the core curriculum in England and Wales for children aged five upwards, primary school teachers have moved from widespread diffidence to positions of some confidence and success in teaching it. In the process, their views of the nature of science and the purposes of teaching it can be expected to have developed. The importance of the teacher in relation to the quality of students' learning, and to the ideas about and orientations towards a subject that students develop, is well documented. There are good reasons to believe that teachers' views of the nature of science form part of a ‘hidden curriculum’ in their science teaching: thus, an understanding of them is necessary to an understanding of learners' experiences of science teaching. The research reported explored such views through both case study and survey methodologies. The case studies showed the depth and subtlety of some teachers' views of science. The survey data yielded six factors, explaining 82% of the variance in respondents' views of science, provisionally named scientism, naive empiricism, ‘new-age-ism’, constructivism, pragmatism and scepticism. The views of science expressed by teachers in interview, and those inferred from and made explicit in their practice, were in most cases consistent with their positions on these factors. These enable interesting insights into the representations of science communicated by primary teachers in their science teaching, which could inform curriculum development in relation to the nature of science, at both primary and secondary levels. 相似文献

This paper describes a case study focusing on the subject matter knowledge, pedagogical content knowledge, and beliefs about science teaching of student teachers in Turkey at the start of their university education. The topic of interest was that of teaching chemical reactions in secondary chemistry education. A written test was developed which used the research literature on potential student misconceptions with regard to different aspects of chemical reactions. Thirty beginning science student teachers were tested, with an additional eight interviews from the student teachers in the same sample. The interviews focused on student teachers’ views about how to best teach chemical reactions in lower secondary chemistry classes. The results revealed deficits in the subject matter knowledge of the student teachers. It also became obvious that the teachers in this sample held very traditional and teacher-centred beliefs when it came to chemistry teaching at the secondary level. Their teaching attitudes were geared mainly towards the acquisition of facts by pupils, and often ignored the development of process-oriented skills. Implications for science teacher education are discussed. 相似文献

The purpose of this research was to understand how preservice elementary teacher experiences within the context of reflective science teacher education influence the development of professional knowledge. We conducted a case analysis to investigate one preservice teacher's beliefs about science teaching and learning, identify the tensions with which she grappled in learning to teach elementary science, understand the frames from which she identified problems of practice, and discern how her experiences played a role in framing and reframing problems of practice. The teacher, Barbara, encountered tensions in thinking about science teaching and learning as a result of inconsistencies between her vision of science teaching and her practice. Confronting these tensions between ideals and realities prompted Barbara to rethink the connections between her classroom actions and students' learning and create new perspectives for viewing her practice. Through reframing, she was able to consider and begin implementing alternative practices more resonant with her beliefs. Barbara's case illustrates the value of understanding prospective teachers' beliefs, their experiences, and the relationship between beliefs and classroom actions. Furthermore, the findings underscore the significance of offering reflective experience as professionals early in the careers of prospective teachers. © 1999 John Wiley & Sons, Inc.

Misconceptions about science are often not corrected during study when they are held with high confidence. However, when corrective feedback co-activates a misconception together with the correct conception, this feedback may surprise the learner and draw attention, especially when the misconceptions are held with high confidence. Therefore, high-confidence misconceptions might be more likely to be corrected than low-confidence misconceptions. The present study investigates whether this hypercorrection effect occurs when students read science texts. Effects of two text formats were compared: Standard texts that presented factual information, and refutation texts that explicitly addressed misconceptions and refuted them before presenting factual information. Eighth grade adolescents (N = 114) took a pre-reading test that included 16 common misconceptions about science concepts, rated their confidence in correctness of their response to the pre-reading questions, read 16 texts about the science concepts, and finally took a post-test which included both true/false and open-ended test questions. Analyses of post-test responses show that reading refutation texts causes hypercorrection: Learners more often corrected high-confidence misconceptions after reading refutation texts than after reading standard texts, whereas low-confidence misconceptions did not benefit from reading refutation texts. These outcomes suggest that people are more surprised when they find out a confidently held misconception is incorrect, which may encourage them to pay more attention to the feedback and the refutation. Moreover, correction of high-confidence misconceptions was more apparent on the true/false test responses than on the open-ended test, suggesting that additional interventions may be needed to improve learners' accommodation of the correct information. 相似文献

This article reports on a three‐year ethnographic study with an experienced elementary science teacher and describes the role of her positive and negative emotions in constructing her science pedagogy, curriculum planning, and relationships with children and colleagues. Examples are offered of the different emotional experiences she related to her science teaching, and it is shown how insights from this research are useful and significant to researchers and educators who want to improve science teaching and learning. A conceptual and methodological framework developed by the author that is based on an interdisciplinary approach in researching emotions is presented. Finally, some implications of researching emotions for elementary science teacher education and science education reform are suggested. © 2002 John Wiley & Sons, Inc.

Understanding the interaction between internally constructed and externally imposed aspects of the teaching context may be the missing link between calls for school reform and teachers' interpretation and implementation of that reform. Although the context of the local school culture has a profound impact on teachers, there are other external forces that are specifically aimed at influencing teachers' pedagogical and curricular decisions. These externally imposed aspects of context include some of the existing tools of reform, such as national standards, mandated state core curricula, and related criterion‐referenced testing. However, little is known about how these reform tools impact teachers' thinking about science and science teaching or how teachers respond to such tools. This study examined the interactions between individual teachers' beliefs about teaching and learning science in elementary school and the tools of reform that are imposed upon them. Comparative case studies were conducted in which two elementary teachers' science instruction, teaching context, and related beliefs were examined, described, and analyzed. In this study, the teachers' fundamental beliefs about science and what it means to teach and learn science influenced their interpretations of the sometimes contradictory messages of reform as they are represented in the standards, mandated curriculum, and end‐of‐level tests. Suggestions about what these findings mean for needed aspects of teacher professional development are offered. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 44: 396–423, 2007 相似文献

Several studies have suggested that preservice teacher education has little impact on student teacher conceptions about various
facets of teaching and learning. Most of these studies refer to generic teaching and learning, and very few have related to
primary science in particular. To explore this area eight primary student teachers were interviewed on six occasions during
the first two years of their Bachelor of Teaching degree. This paper reports the findings from part of these interviews. It
describes the (sometimes changing) conceptions which these eight students held about how they would recognise a “good” teacher
of science and the people and experiences they believed influenced the formation of these views. The differential impact of
past and present teachers and the teacher education program revealed possible implications for practica and science curriculum
units in particular, if teacher education is going to have an influence on preservice teachers' conceptions about teaching
and learning. 相似文献

Teaching science as explanation is fundamental to reform efforts but is challenging for teachers—especially new elementary teachers, for whom the complexities of teaching are compounded by high demands and little classroom experience. Despite these challenges, few studies have characterized the knowledge, beliefs, and instructional practices that support or hinder teachers from engaging their students in building explanations. To address this gap, this study describes the understandings, purposes, goals, practices, and struggles of one third-year elementary teacher with regard to fostering students' explanation construction. Analyses showed that the teacher had multiple understandings of scientific explanations, believed that fostering students' explanations was important for both teachers and students, and enacted instructional practices that provided opportunities for students to develop explanations. However, she did not consistently take up explanation as a goal in her practice, in part because she did not see explanation construction as a strategy for facilitating the development of students' content knowledge or as an educational goal in its own right. These findings inform the field's understanding of teacher knowledge and practice with regard to one crucial scientific practice and have implications for research on teachers and inquiry-oriented science teaching, science teacher education, and curriculum materials development. 相似文献

As a key element in teacher education programmes, action research is a learning process in which pre-service teachers inquire, reflect on and improve their teaching practices. This qualitative study sought to understand what enhanced or hindered Thai pre-service teachers' action research projects during their student teaching. This study drew upon written reflections, focus-group interviews and observations of seminar sessions. Data analysis was inductive, involving categorical aggregation followed by a search for correspondence and patterns. The results indicated that the pre-service teachers misunderstood action research, and also held a negative attitude toward it, both of which led them to superficial analyses of practice. They struggled with time limitations, data gathering and interpretation strategies. In spite of the struggles they experienced, these pre-service science teachers did learn more about the action research through collaboratively working with cooperating teachers and university supervisors and on-campus seminar discussions held concurrently with the fifth year internship. Recognizing and understanding the reasons and thinking patterns at the root of these teachers' difficulties with learning about action research can form the basis for reflecting on and rethinking the components of science teacher preparation programmes in Thailand. 相似文献

This study has two aims. The first one is to reveal the science teacher candidates’ misconceptions about the density by using a four-tier diagnostic test, and the second one is to determine to what extent science teacher candidates have scientific knowledge, lack of knowledge, and misconceptions about the density. In order to achieve these aims, a four-tier density diagnostic test was developed with the KR-20 reliability coefficient of 0.753 based on the correct answers, and the KR-20 reliability coefficient of 0.528 based on the misconceptions. To determine the misconceptions about the density with the developed test, data were collected from a total of 470 science teacher candidates from seven different universities in Turkey. With the developed four-tier diagnostic test, 48 different misconceptions were revealed. The results of the research showed that about one fourth of science teacher candidates had a misconception about the density and that the ratio of six of the resulting misconceptions was over 10%. It may be suggested that this study conducted on science teacher candidates should also be conducted on middle and high school students and experimental studies should be carried out to eliminate the misconceptions that emerged in this study.

This study unveils the stories of 3 public school elementary teachers from the USA who reflected on their beliefs about science education reform, and implementation of the reform in their classroom teaching, in response to state recommendations for change in science education. The teachers' stories show how various factors assisted or impeded the implementations of reform in their teaching, the various challenges related to their grade-level teaching, and the teachers' personal struggles to make sense of reform recommendations. Within each case study, we describe 4 common themes from the teachers' interviews. These themes are related to teachers' science teaching strategies, their science teaching efficacy beliefs about adopting reform, the types of science learning outcomes teachers target, and the types of teaching resources available to them. Implications for teacher education and practice are discussed in relationship with study findings. 相似文献

This study investigated whether or not an increase in secondary science teacher knowledge about evolution and the nature of
science gained from completing a graduate-level evolution course was associated with greater preference for the teaching of
evolution in schools. Forty-four precertified secondary biology teachers participated in a 14-week intervention designed to
address documented misconceptions identified by a precourse instrument. The course produced statistically significant gains
in teacher knowledge of evolution and the nature of science and a significant decrease in misconceptions about evolution and
natural selection. Nevertheless, teachers’ postcourse preference positions remained unchanged; the majority of science teachers
still preferred that antievolutionary ideas be taught in school. 相似文献

This study examined Malaysian science teachers' pedagogical content knowledge (PCK) of selected physics concepts. The two components of PCK investigated were (i) knowledge of students' understanding, conceptions and misconceptions of topics, and (ii) knowledge of strategies and representations for teaching particular topics. The participants were 12 trainee teachers from various academic science backgrounds attending a one-year postgraduate teacher-training course. They were interviewed on selected basic concepts in physics that are found in the Malaysian Integrated Science curriculum for lower secondary level. The findings showed that trainee teachers' PCK for promoting conceptual understanding is limited. They lacked the ability to transform their understanding of basic concepts in physics required to teach lower secondary school science pupils. The trainees' level of content knowledge affected their awareness of pupils' likely misconceptions. Consequently, the trainees were unable to employ the appropriate teaching strategies required to explain the scientific ideas. This study provides some pedagogical implications for the training of science teachers. 相似文献

The question of where to locate teaching about the relationships between science and religion has produced a long-running debate. Currently, science and religious education (RE) are statutory subjects in England and are taught in secondary schools by different teachers. This paper reports on an interview study in which 16 teachers gave their perceptions of their roles and responsibilities when teaching topics that bridge science and religion and the extent to which they collaborated with teachers in the other subject areas. We found that in this sample, teachers reported very little collaboration between the curriculum areas. Although the science curriculum makes no mention of religion, all the science teachers said that their approaches to such topics were affected by their recognition that some pupils held religious beliefs. All the RE teachers reported struggling to ensure students know of a range of views about how science and religion relate. The paper concludes with a discussion about implications for curriculum design and teacher training. 相似文献

Pre‐service teachers face many challenges as they learn to teach in ways that are different from their own educational experiences. Pre‐service teachers often enter teacher education courses with pre‐conceptions about teaching and learning that may or may not be consistent with contemporary learning theory. To build on preservice teachers' prior knowledge, we need to identify the types of views they have when entering teacher education courses and the views they develop throughout these courses. The study reported here focuses specifically on preservice teachers' views of their own students' prior knowledge and the implications these views have on their understanding of the formative assessment process. Sixty‐one preservice teachers were studied from three sections of a science methods course. Results indicate that preservice teachers exhibited a limited number of views about students' prior knowledge. These views tended to privilege either academic or experience‐based concepts for different aspects of formative assessment, in contrast to contemporary perspectives on teaching for understanding. Rather than considering these views as misconceptions, it is argued that it is more useful to consider them as resources for further development of a more flexible concept of formative assessment. Four common views are discussed in detail and applied to science teacher education. © 2008 Wiley Periodicals, Inc. J Res Sci Teach 45: 497–523, 2008 相似文献

Conclusion The basic assumption underlying this study is that science teachers have misconceptions in some selected science concepts.
The overall conclusion which can be drawn is that, although the responses were not consistent across the concepts or within
the concepts, there are indeed misconceptions. The result is evidence that the graduate trainee teachers have misconceptions
in science. The results show that the view of science held by this group of trainee teachers is sometimes little better than
the view of science held by students investigated by Osborne et al. The test appears appropriate for use with science teachers.
What do these results imply? They suggest that science teachers may have concepts which are little better than the students
they teach. If that is the case, then, is it reasonable to urge teachers to probe their students' concepts before teaching
them? Should science educators then redirect their efforts in conceptual change to changing teachers' views before changing
students' views? 相似文献
