In order to understand how prospective teachers develop knowledge for teaching, researchers must identify the types of knowledge that are integral to effective science teaching. This case study investigated how 4 prospective secondary biology teachers’ science teaching orientations, knowledge of science learners, and knowledge of instructional sequence, developed during a post-baccalaureate teacher education program. Data sources included a lesson planning task and two interview-observation cycles during the participants’ year-long internship. Over the course of a year, the participants’ science teaching orientations were based primarily on their K-16 learning experiences, and were robust and highly resistant to change. The prospective teachers became more aware of student learning difficulties, and therefore, developed more elaborated knowledge of the requirements of learning. They consistently sequenced instruction in ways that gave priority to transmitting information to students. Prospective teachers’ development of knowledge of student understanding of science and instructional sequence were congruent with their science teaching orientations. Implications are given for teacher education and future research.  相似文献

The study compared candidates in a 4-year undergraduate program for secondary mathematics and science teaching, based on the UTeach model, with candidates in a 1-year postbaccalaureate program at the same institution. Candidates in the undergraduate program participated in a partnership of university mathematics, science, and education departments and intensive field-based experiences in high-needs schools. We conjectured that this approach would better prepare prospective teachers to develop beginning teacher competencies. Analysis of the Performance Assessment for California Teachers Teaching Event identified few differences between candidates in both groups. Surveys revealed significant differences between candidates’ perceptions of their preparation for teaching. These findings suggest that different program models can offer differential support to prospective teachers but how the program features are enacted influences the impact that these programs have on teacher preparation.  相似文献

Given the high attrition rate of beginning science teachers, it is imperative to better prepare science preservice teachers, so that they can be successful during the early years of their teaching. The purpose of this study was to explore science preservice teachers’ views of themselves as a future teacher, in particular their hopes and fears for science teaching and the experiences that help to shape their possible selves. Employed were qualitative methods, which included open-ended surveys and face-to-face interviews. Eleven preservice teachers who enrolled in a secondary science teacher preparation program participated. Findings showed six categories of future selves with the most frequent category being for effective/ineffective science teaching. When their hoped-for and feared selves were not balanced, participants articulated more fears. Regarding the primary influence in shaping their hopes and fears, diverse past experiences related to teaching and learning appeared to be more salient factors than science teacher education program. Given the enriched understanding of the science preservice teachers’ perceptions, we provided suggestions for science teacher educators.  相似文献

Developing pre-service science teachers’ epistemic insight remains a challenge, despite decades of research in related bodies of work such as the nature of science (NOS) in science education. While there may be numerous aspects to this problem, one critical element is that the NOS is a meta-concept that demands higher-order cognitive skills. One possible strategy to facilitate pre-service teachers’ understanding of epistemic aspects of science is visualisation. Visual representations of objects and processes can be tools for developing and monitoring understanding. Although the NOS and visualisation literatures have been studied extensively, the intersection of these bodies of literatures has been minimal. Incorporating visual tools on the NOS in teacher education is likely to facilitate teachers’ learning, eventually impacting their students’ learning of the NOS. The objective of this paper is to illustrate how the visual tools of scientific knowledge and practices aspects of the NOS can be integrated in science teacher education in order to develop pre-service teachers’ epistemic insight. The paper presents an empirical study that incorporated visual tools about the NOS in primary science teacher education. Data on 14 pre-service teachers’ are presented along with in-depth case studies of 3 pre-service teachers illustrating the influence of the teacher education intervention. The qualitative analysis of visual representations before and after the intervention as well as verbal data suggests that there was improvement in pre-service teachers’ perceptions of the NOS. Implications for future research on visualisation of the NOS are discussed.  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.

This study explored teacher perspectives on the use of socioscientific issues (SSI) and on dealing with ethics in the context of science instruction. Twenty‐two middle and high school science teachers from three US states participated in semi‐structured interviews, and researchers employed inductive analyses to explore emergent patterns relative to the following two questions. (1) How do science teachers conceptualize the place of ethics in science and science education? (2) How do science teachers handle topics with ethical implications and expression of their own values in their classrooms? Profiles were developed to capture the views and reported practices, relative to the place of ethics in science and science classrooms, of participants. Profile A comprising teachers who embraced the notion of infusing science curricula with SSI and cited examples of using controversial topics in their classes. Profile B participants supported SSI curricula in theory but reported significant constraints which prohibited them from actualizing these goals. Profile C described teachers who were non‐committal with respect to focusing instruction on SSI and ethics. Profile D was based on the position that science and science education should be value‐free. Profile E transcended the question of ethics in science education; these teachers felt very strongly that all education should contribute to their students' ethical development. Participants also expressed a wide range of perspectives regarding the expression of their own values in the classroom. Implications of this research for science education are discussed. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 353–376, 2006  相似文献

This study investigated how a collaborative mentoring program influenced beginning science teachers' inquiry-based teaching and their reflection on practice. The one-year program consisted of five one-on-one mentoring meetings, weekly science education seminars, weekly mentoring group discussions, and self-evaluation activities. The participants were three beginning science teachers and three mentors at the middle school level (7–9th grades) in an urban area of South Korea. For each beginning teacher, five lessons were evaluated in terms of lesson design/implementation, procedural knowledge, and classroom culture by using the Reformed Teaching Observation Protocol. Five aspects of the beginning teachers' reflections were identified. This study showed that a collaborative mentoring program focusing on inquiry-based science teaching encouraged the beginning teachers to reflect on their own perceptions and teaching practice in terms of inquiry-based science teaching, which led to changes in their teaching practice. This study also highlighted the importance of collaborative interactions between the mentors and the beginning teachers during the mentoring process.  相似文献

The educational reform movement since the 1990s has led the secondary earth science curriculum in Taiwan into a stage of reshaping. The present study investigated secondary earth science teachers' perceptions on the Goals of Earth Science Education (GESE). The GESE should express the statements of philosophy and purpose toward which educators direct their attention, and provide the visions or broad aims that earth science education is designed to achieve. Based on this rationale, the purpose of this study was to explore teachers' perceptions on the GESE at secondary school level (Grades 7–12) in Taiwan. A national survey of 1,000 earth science teachers was conducted in May 2004, with a response rate of 70.2%. The results revealed that ‘Students acquire basic earth science concepts’ is the most important GESE both in teachers' preferred goal and their actual teaching practice in the secondary earth science education; that there is a major gap between teachers' preferred and actual GESE in terms of ‘Preparing students for the entrance examinations’; and that the differences between teachers' preferred and actual GESE are contingent on the teachers' age, the school size, and the teacher education background of teachers.  相似文献

Quality mentoring is fundamental to preservice teacher education because of its potential to help student and novice teachers develop the academic and pedagogical knowledge and skills germane to successful induction into the profession. This study focused on Jordanian preservice primary teachers' perceptions of their mentoring experiences as these pertain to science teaching. The Mentoring for Effective Primary Science Teaching instrument was administered to 147 senior preservice primary teachers in a university in Jordan. The results indicated that the greater majority of participants did not experience effective mentoring toward creating a supportive and reflexive environment that would bolster their confidence in teaching science; further their understanding of primary science curriculum, and associated aims and school policies; help with developing their pedagogical knowledge; and/or furnish them with specific and targeted feedback and guidance to help improve their science teaching. Substantially more participants indicated that their mentors modeled what they perceived to be effective science teaching. The study argues for the need for science-specific mentoring for preservice primary teachers, and suggests a possible pathway for achieving such a model starting with those in-service primary teachers—much like those identified by participants in the present study—who are already effective in their science teaching.  相似文献

The study aimed to assess the adequacy of pre-service teacher education in Turkey as perceived by preservice teachers. Specifically, the researchers investigated preservice teachers’ perceptions of the adequateness of their education in terms of developing teaching skills and the major components of teacher education. The factors affecting their perceptions were also examined. In total, 1856 preservice teachers participated in the study. A questionnaire was prepared to collect data from the participants. According to the findings, teacher education should be enhanced in terms of preparing candidates for skills such as teaching in different contexts and cooperating with parents; and practicum hours needed to be improved for more effective preparation of preservice teachers. Moreover, it was also found that the preservice teachers’ subject, college, orientation towards teaching and the perceived adequacy of program components played significant roles in affecting their perceptions of teacher education.  相似文献

A large body of literature illustrates that many elementary teachers are reluctant to teach science and confess a lack of confidence to teach it. Nevertheless, a review of the literature indicates a few cases of elementary teachers who do well in science and offers rare examples of enthusiast elementary teachers. The question then becomes how those cases came to be? The purpose of this study is to document two such cases of prospective elementary teachers, illustrate their unique characteristics and shed light on how those came to be. The study was designed upon a narrative inquiry approach focusing on the collection of personal stories. Multiple sources of data were used in order to examine the participants’ science teaching orientations and the kinds of experiences that influenced their development: drawings, interviews, reflective assignments, and others. The analysis of the data was grounded within the Three-Dimensional Space Narrative Structure. The findings of the analysis illustrated that the participants perceived certain experiences they had during their university coursework as critical to shaping their orientations to science and science teaching: inquiry-based investigations, contemporary theoretical discussions, outdoors field study, friendly classroom environment and the characteristics of their instructors. These findings have implications for the design of teacher education courses that aim to engage prospective elementary teachers, especially females, in meaningful learning experiences and support them in developing science teaching orientations that are in line with reform recommendations.  相似文献

Inquiry-based science instruction (IBSI) has the potential to contribute to social justice through widening participation and success in science. However, teachers struggle to implement IBSI because of contextual factors. The purpose of this paper is to explore the use of agency as a framework for understanding teachers’ decision-making, by asking the question: what was the agency of six science teachers in their social-justice aspirations and use of IBSI? An agency framework recognizes that teachers’ decisions are informed by their internal conversations at the intersection of personal aspects (their history, repertoire, and aspirations) with the cultural and structural constraints and resources of their contexts. However, research on IBSI has focussed on teachers’ personal aspects or their perceptions of contextual factors. The sample had learnt IBSI through service learning in the context of a science fair. From teacher interviews, it emerged that these teachers had strong social-justice aspirations to serve disadvantaged students. The teachers linked their social-justice aspirations to their choice of school rather than their use of IBSI. The teachers at better-resourced schools initiated participation in science fairs at their schools, whilst the rest judged that science fairs were not appropriate for their students. The results suggest that, rather than prescribing particular pedagogies, teacher education programmes should aim to increase teachers’ pedagogical repertoires, in order to enrich their agency in whatever contexts they teach.

This study investigated changes in Korean science teachers' perceptions of creativity and science teaching after participating in an overseas professional development program. Participants were 35 secondary science teachers. Data were collected from open-ended questionnaires and interviews. Results indicated that participants showed a growing awareness that creativity can be expressed by every student; creativity can be enhanced; science has a much wider range of activities that foster creativity; and creativity-centered science teaching can be implemented in Korea. The major elements of the professional program that promoted these perceptual changes included hands-on creativity activities, observation of creativity-centered classrooms, and discussion with other teachers. Follow-up study revealed that their perceptual changes have been reflected in their teaching practices.  相似文献

This study aimed to assess the influence of a philosophy of science (POS) course on science teachers’ views of nature of science (NOS), perceptions of teaching about NOS, and instructional planning related to NOS. Participants were 56 undergraduate and graduate preservice secondary science teachers enrolled in a two science‐methods course sequence, in which participants received explicit, reflective NOS instruction. Ten of these participants were also enrolled in a graduate survey POS course. The Views of Nature of Science Questionnaire — Form C coupled with individual interviews was used to assess participants’ NOS views at the beginning and conclusion of the study. Participants’ lesson plans and NOS‐specific reflection papers were analysed to assess the impact of the POS course on their instructional planning related to, and perceptions of teaching about, NOS. Results indicated that, compared with participants enrolled in the methods courses, the POS course participants developed deeper, more coherent understandings of NOS. Substantially more of these latter participants planned explicit instructional sequences to teach about NOS. Additionally, the POS course participants’ discourse regarding NOS progressed from a preoccupation with the technical, to a concern with the practical, and, finally, to a focus on the emancipatory. Their views of teaching about NOS in their future classrooms went beyond the customary discourse of whether pre‐college students should or could be taught about NOS, to contemplating changes they needed to bring about in their own teaching behaviour and language to achieve consistency with their newly acquired NOS understandings.  相似文献

Professional Learning Communities (PLCs) are frequently being used as a vehicle to transform science education. This study explored elementary teachers' perceptions about the impact of participating in a science PLC on their own professional development. With the use of The Science Professional Learning Communities Survey and a semi-structured interview protocol, elementary teachers' perceptions of the goals of science PLCs, the constraints and benefits of participation in PLCs, and reported differences in the impact of PLC participation on novice and experienced teachers were examined. Sixty-five elementary teachers who participated in a science PLC were surveyed about their experiences, and a subsample of 16 teachers was interviewed. Results showed that most of the teachers reported their science PLC emphasized sharing ideas with other teachers as well as working to improve students' science standardized test scores. Teachers noted that the PLCs had impacted their science assessment practices as well as their lesson planning. However, a majority of the participants reported a differential impact of PLCs depending on a teacher's level of experience. PLCs were reported as being more beneficial to new teachers than experienced teachers. The interview results demonstrated that there were often competing goals and in some cases a loss of autonomy in planning science lessons. A significant concern was the impact of problematic interpersonal relationships and communication styles on the group functioning. The role of the PLC in addressing issues related to obtaining science resources and enhancing science content knowledge for elementary science teachers is discussed.  相似文献

This paper examines upper elementary and middle school teachers’ learning of mathematics and science content, how their perceptions of their disciplines and learning of that discipline developed through content-rich learning experiences, and the differences and commonalities of the teachers’ learning experiences relative to content domain. This work was situated within a larger professional development (PD) program that had multiple, long-term components. Participants’ growth occurred in 4 primary areas: knowledge of content, perceptions of the discipline, perceptions about the learning of the discipline, and perceptions regarding how students learn content. Findings suggest that when embedded within an effective professional development context, content can be a critical vehicle through which change can be made in teachers’ understandings and perceptions of mathematics and science. When participants in our study were able to move beyond their internal conflicts and misunderstandings, they could expand their knowledge and perceptions of content and finally bridge to re-conceptualize how to teach that content. These findings further indicate that although teachers involved in both mathematics and science can benefit from similar overall PD structures, there are some unique challenges that need to be addressed for each particular discipline group. This study contributes to what we understand about teacher learning and change, as well as commonalities and differences between teachers’ learning of mathematics and science.  相似文献

Informal science education institutions (ISEIs), such as museums, aquariums, and nature centers, offer more to teachers than just field trip destinations—they have the potential to provide ideas for pedagogy, as well as support deeper development of teachers’ science knowledge. Although there is extensive literature related to teacher/museum interactions within the context of the school field trip, there is limited research that examines other ways that such institutions might support classroom teachers. A growing number of studies, however, examine how incorporating such ideas of connections of ISEIs to pre-service teacher education might improve teacher perceptions and awareness. Pre-service elementary teachers enrolled in a science methods class participated in a semester-long assignment which required participation in their choice of activities and events (workshops, field trips, family day activities) conducted at local ISEIs. Students generally saw this embedded assignment as beneficial, despite the additional out-of-class time required for completion. Comparison of pre-/post-class responses suggested that teachers shifted their perceptions of ISEIs as first and foremost as places for field trips or hands-on experiences, to institutions that can help teachers with classroom science instruction. Although basic awareness of the existence of such opportunities was frequently cited, teachers also recognized these sites as places that could enhance their teaching, either by providing materials/resources for the classroom or by helping them learn (content and pedagogy) as teachers. Implications for practice, including the role of ISEIs in teacher preparation and indication, are also discussed.  相似文献

The nature of science (NOS) has become a central goal of science education in many countries. This study refers to a developmental work research program, in which four fifth-grade elementary in-service teachers participated. It aimed to improve their understandings of NOS and their abilities to teach it effectively to their students. The 1-year-long, 2012–2013, program consisted of a series of activities to support teachers to develop their pedagogical content knowledge of NOS. In order to accomplish our goal, we enabled teacher-researchers to analyze their own discourse practices and to trace evidence of effective NOS teaching. Many studies indicate the importance of examining teachers’ discussions about science in the classroom, since it is teachers’ understanding of NOS reflected in these discussions that will have a vital impact on students’ learning. Our proposal is based on the assumption that reflecting on the ways people form meanings enables us to examine and seek alternative ways to communicate aspects of NOS during science lessons. The analysis of discourse data, which has been carried out with the teacher-researchers’ active participation, indicated that initially only a few aspects of NOS were implicitly incorporated in teacher-researchers’ instruction. As the program evolved, all teacher-researchers presented more informed views on targeted NOS aspects. On the whole, our discourse-focused professional development program with its participatory, explicit, and reflective character indicated the importance of involving teacher-researchers in analyzing their own talk. It is this involvement that results in obtaining a valuable awareness of aspects concerning pedagogical content knowledge of NOS teaching.  相似文献

This paper explores one district’s attempt to implement a blended science and English Language Development (ELD) elementary program, designed to provide English language learners opportunities to develop proficiency in English through participation in inquiry-based science. This process resulted in blended program that utilized a combined science/ELD lesson plan format to structure and guide teachers’ efforts to use science as the context for language development. Data, collected throughout the first 2 years of the program, include teacher-generated lesson plans, observation notes, and interviews with teachers and principals. The process by which the blended program was developed, the initial implementation of the program, the resulting science/ELD lesson plan format, and teachers’ perceptions about the program and its impact on their students are described.  相似文献
