An important task of science teachers should be to take pupils’ (pre)conceptions and learning difficulties into account and to negotiate about the meanings of specific concepts. In this context, teachers’ pedagogical content knowledge plays an important role. This article presents an international study of Dutch, Finnish, English and Greek pre-service teachers’ conceptions and concerns of how to teach the concept of combustion. The prospective science teachers were invited to prepare a lesson about this concept for pupils of junior secondary school level. The prospective teachers were not allowed to consult any textbook. Research data were obtained from audio-taped semi-structured interviews with the prospective teachers. In addition, their written lesson plans and their answers to an accompanying questionnaire were collected and analysed. The results reveal a number of important characteristics of prospective teachers’ views and concerns regarding the teaching of combustion. The implications of the study for science teacher education will be presented. 相似文献

This study explored whether early childhood preservice teachers' concerns about teaching nature of science (NOS) and their intellectual levels influenced whether and how they taught NOS at the preschool and primary (K‐3) levels. We used videotaped classroom observations and lesson plans to determine the science instructional practices at the preschool and primary levels, and to track whether and how preservice teachers emphasized NOS. We used the Stages of Concern Questionnaire (SOCQ) pre‐ and postinternship to determine concerns about NOS instruction, and the Learning Context Questionnaire (LCQ) to determine intellectual levels. We found that neither concerns about teaching NOS nor intellectual level were related to whether and how the preservice teachers emphasized NOS; however, we found that all preservice early childhood teachers began their internships with NOS concern profiles of “worried.” Two preservice teachers' NOS concerns profiles changed as a result of their internships; one to “cooperator” and one to “cooperator/improver.” These two preservice teachers had cooperating teachers who were aware of NOS and implemented it in their own science instruction. The main factors that hindered or facilitated teaching NOS for these preservice teachers were the influence of the cooperating teacher and the use of the science curriculum. The preservice teacher with the cooperating teacher who understood and emphasized NOS herself and showed her how to modify the curriculum to include NOS, was able to explicitly teach NOS to her students. Those in classrooms whose cooperating teachers did not provide support for NOS instruction were unable to emphasize NOS. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 47:213–233, 2010 相似文献

While there is a growing literature focused on doctoral preparation for teaching about science teaching, rarely have recommendations extended to preparation for teaching science content to teachers. We three doctoral students employ self-study as a research methodology to investigate our developing pedagogical content knowledge for teaching science to teachers during a mentored internship in an elementary teacher professional development program. With our mentor, we examine critical incidents in the experience that supported new insights about teaching teachers and about ways in which beginning teacher educators need to develop their existing pedagogical content knowledge for teaching science to students in order to teach science effectively to teachers. We emphasize ways in which doctoral internships can support this learning and how our respective cultures shaped our interactions with and perceptions of teachers as learners. 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

This paper uses a possible selves theoretical framework to examine whether and how adolescent girls' images of themselves as future scientists change during their transition from high school to college. Forty-one female high school graduates from diverse ethnic and socioeconomic backgrounds, who had enrolled in an intensive math and science program while in high school, participated in interviews focused on their perceptions of factors that influenced their career plans over time. Participants suggested that career-related internships and intensive academic programs, especially those that yielded important mentoring relationships, were contexts in which they negotiated career-related possible selves and subsequent career plans. 相似文献

The purpose of this case study is to delve into the complexities of how preservice science teachers’ science teaching orientations, viewed as an interrelated set of beliefs, interact with the other components of pedagogical content knowledge (PCK). Eight preservice science teachers participated in the study. Qualitative data were collected in the form of content representation, responses to an open-ended instrument, and semi-structured interviews. Preservice teachers’ orientation and PCK were analyzed deductively. Constant comparison analysis of how their orientation interacted with other PCK components revealed three major themes: (1) one’s purpose for science teaching determines the PCK component(s) with which it interacts, (2) a teacher’s beliefs about the nature of science do not directly interact with his/her PCK, unless those beliefs relate directly to the purposes of teaching science, and (3) beliefs about science teaching and learning mostly interact with knowledge of instructional strategies. Implications for science teacher education and research are discussed. 相似文献

We use a unique longitudinal sample of student teachers (“interns”) from six Washington state teacher training institutions to investigate patterns of entry into the teaching workforce. We estimate split population models that simultaneously estimate the impact of individual characteristics and student teaching experiences on the timing and probability of initial hiring as a public school teacher. Not surprisingly, we find that interns endorsed to teach in “difficult-to-staff” areas are more likely to find employment as public school teachers than interns endorsed in other areas. Younger interns, white interns, and interns who completed their student teaching in suburban schools are also more likely to find a teaching job, all else equal. Prospective teachers who do their internships at schools that have more teacher turnover are more likely to find employment, often at those schools. On the other hand, few of the characteristics of an intern's cooperating teacher are predictive of workforce entry. Finally, interns with higher credential exam scores are more likely to be hired by the school where they did their student teaching. 相似文献

Efforts to promote more realistic conceptions about science are often limited by teachers’ inexperience in this domain. In this paper, we describe an ‘inductive–deductive, dialectic immersion’ approach towards assisting teachers in developing more realistic conceptions about science — along with corresponding revised perspectives about science teaching. Three secondary teachers of science with minimal science research experience engaged in a case study of science in action — specifically, in an episode of northern alpine ecological field research. Qualitative data analyzed by constant comparative methods suggested that these teachers shifted along a modernist through postmodernist continuum — as indicated by increased support for a more Naturalist epistemology of science, a more Antirealist ontology of science, and corresponding priorities towards science teaching and learning. Results suggest that teachers of science can develop postmodern views about science and science teaching if given opportunities to induce and deduce propositions about science in realistic cases of science in action. 相似文献

This article extends the literature on teachers’ career paths by attending to the experiences of educators when they were students in secondary classrooms. Grounded in the perspective that biography is central to teaching, we investigate undergraduate pre-service teachers’ educational experiences, views on teaching and learning, and professional plans. We draw upon life history interviews with 40 prospective teachers at three institutions across Pennsylvania, USA. We find that past educational experiences are intricately connected with career choice, intended professional path, and pedagogical focus. This paper identifies and discusses three forms of modeling – disciplinary, mentoring, and empowering – which influence pre-service teachers in powerful and enduring ways. These forms of modeling expand our understanding of teachers’ career intentions and apply the apprenticeship of observation to planned career paths. 相似文献

This study chronicled the professional journeys of two beginning science teachers. The focus of the research effort documents
what brought them to science teaching and investigated their resulting career paths. Data artifacts for this instrumental
case study approach included: interviews, written survey responses, personal communications and member checks. All data was
transcribed and coded into emergent categories using a constant comparative analysis approach. The findings indicated that
their decisions to enter and leave teaching were a complex mélange of issues that included career disposition, notions of
isolation, overarching culture of the school, and future possibilities. However, most striking was their re-entry into teaching
on a temporary basis after considerable time away from the classroom, which suggests that teachers develop a sense of agency
regarding their career decisions. This may require researchers to reconsider how we view teacher decision-making within the
context of teacher attrition and mobility. Implications for science teacher education indicate that some teachers may enter
the profession considering teaching to be a transition into a different career path. Secondary science teachers may perceive
multiple career options (beyond the classroom) based on their preparation and teaching experience. Further implications and
possibilities for science teacher education are discussed. 相似文献

A new science curriculum, with a significant emphasis on modelling, was recently adopted in Danish lower secondary education. The theoretical intentions behind the new curriculum include substantial changes to how teachers should address models and modelling in their practice. The purpose of this study is to analyse the alignment between the intentions and arguments for integrating models and modelling into science education, on the one hand, and teachers’ practices and rationales for integrating models and modelling into their teaching practice, on the other. First, this study outlines a theoretical competence-oriented modelling framework. This framework describes what kind of knowledge and practice of models and modelling needs to be integrated into teaching to accomplish a competence-oriented approach in this regard. Second, against the background of this framework, we conducted an empirical study of three teacher-teams’ talk about modelling and their practice of integrating models and modelling in their teaching. Our findings suggest that the participating teachers’ practices and rationales for integrating models and modelling into their teaching are characterised by a product-oriented approach that is not well aligned with competence-oriented teaching. Finally, we provide ideas for improving the alignment between theoretical intentions and teachers’ practice, targeted at science educators and curriculum designers.

Teacher beliefs about curriculum design affect the quality of science education in schools, but science researchers know little
about the interrelation of beliefs about alternative curriculum designs. This article describes a quantitative study of secondary
science teachers' beliefs about curriculum design. A 33-item Science Curriculum Orientation Inventory (SCOI) was developed
to measure five distinct orientations to curriculum: academic, cognitive processes, societycentred, humanistic, and technological.
Data were collected from 810 integrated science, chemistry, physics, and biology teachers in Hong Kong. A confirmatory factor
analysis of teacher responses to the SCOI indicated that science teachers' beliefs about curriculum design had a hierarchical
structure; the five distinct curriculum orientations were positively correlated, forming a second-order curriculum, meta-orientation.
Physics teachers were less society-oriented than biology, integrated science and chemistry teachers, and integrated science
teachers were more humanistic than physics teachers. Although science teachers' beliefs about any of the five alternative
curriculum designs did not vary with their teaching experience, the difference between beliefs about the cognitive processes
orientation and the humanistic orientation increased when teachers had gained more teaching experience. Implications of these
findings are discussed. 相似文献

Among the initiatives of the Maryland Collaborative for Teacher Preparation (MCTP) is a summer research internship program
that places preservice middle grades teachers in extended collaboration with professional mathematicians, scientists, and
educators engaged in research and curriculum development activities. We describe the MCTP internship program including the
rationale for and structural features of the program. We also highlight the effects of the internship experience on preservice
teachers' conceptions of and beliefs about the nature and processes of mathematics and science, and the teaching of mathematics
and science. Our findings suggest that the internship experience is a fundamentally significant life experience for preservice
teachers. Furthermore, internships have the potential for realizing reform in mathematics and science education; that is,
preservice teachers who have participated in MCTP internships intend to bring a holistic, conceptually oriented view of mathematics
and science to their classrooms. The paper concludes with a summary of ongoing programmatic and logistical challenges of the
MCTP internship program.

This study investigated what 13 secondary science teachers at various nature of science (NOS) instruction implementation levels talked about when they reflected on their teaching. We then determined if differences exist in the quality of those reflections between high, medium, and low NOS implementers. This study sought to answer the following questions: (1) What do teachers talk about when asked general questions about their pedagogy and NOS pedagogy and (2) what qualitative differences, if any, exist within variables across teachers of varying NOS implementation levels? Evidence derived from these teachers’ reflections indicated that self-efficacy and perceptions of general importance for NOS instruction were poor indicators of NOS implementation. However, several factors were associated with the extent that these teachers implemented NOS instruction, including the utility value they hold for NOS teaching, considerations of how people learn, understanding of NOS pedagogy, and their ability to accurately and deeply self-reflect about teaching. Notably, those teachers who effectively implemented the NOS at higher levels value NOS instruction for reasons that transcend immediate instructional objectives. That is, they value teaching NOS for achieving compelling ends realized long after formal schooling (e.g., lifelong socioscientific decision-making for civic reasons), and they deeply reflect about how to teach NOS by drawing from research about how people learn. Low NOS implementers’ simplistic notions and reflections about teaching and learning appeared to be impeding factors to accurate and consistent NOS implementation. This study has implications for science teacher education efforts that promote NOS instruction. 相似文献

The purposes of this study are to report the influences of a mixed delivery professional development [PD] course involving face-to-face classes and the mentoring assisted inquiry-based teaching [MAIT] website that addressed the conceptual change and self-efficacy of high school mathematics and science teachers’ conceptions of inquiry-based teaching. Twenty-five in-service high school science and mathematics teachers participated in a 9 weeks, 4 h per week PD course. Data collection included the pre-post Inquiry Teaching Efficacy Questionnaire [ITEQ], teachers’ reflective journals posted on the MAIT website, teachers’ assignments requested by the course instructor, and follow-up teachers’ interviews. Findings revealed that both mathematics and science teachers’ conceptions of inquiry teaching show significant improvements after the course. The mixed delivery PD course had the same influence on science and mathematics teachers. The authentic video clips and lesson plans provided on the MAIT website and the specific feedback toward teachers’ performance are the main factors that shaped teachers’ inquiry-based teaching conceptions. 相似文献

This study (a) assessed the influence of an integrated nature of science (NOS) instructional intervention on inservice secondary science teachers' understandings, retention of those understandings, and their NOS instructional planning and practices; and (b) examined factors that mediated the translation of teachers' NOS understandings into practice. Nineteen teachers participated in an intensive, 6-week NOS course, which concluded with teachers developing plans to address NOS in their classrooms. Next, 6 participants were observed as they implemented their instructional plans. Data sources included pretest, posttest, and delayed-test NOS assessments, classroom observations, and several teacher-generated artifacts. The NOS course was effective in helping teachers develop informed NOS conceptions and retain those understandings 5 months after its conclusion. Teachers met with challenges and successes as they attempted to address NOS instructionally. The translation of NOS conceptions into practice was primarily mediated by the very nature of teachers' newly acquired NOS understandings, which were situated within the science contents, contexts, and experiences in which they were developed (i.e. the NOS course); thus, limiting participants' abilities to transfer their understandings into novel contexts and contents. The results helped build a model of the sources of science teachers' pedagogical content knowledge for teaching about NOS in content-rich contexts. 相似文献

Drawing on data from nine secondary school mentor teachers, the authors explore the emotional aspects of mentoring. Embracing a view of ‘cool’ professionalism, the mentors hid from their interns the intensity and complexity of their work as mentors. The authors argue that to maximize the value of mentoring neophyte teachers should be given a glimpse into its difficulty as part of engaging in rich conversations about teaching and learning. 相似文献

This study has two purposes: the first is to explore experienced science teachers’ perspectives on inquiry teaching, and the second is to categorize these perspectives into patterns. Fifteen junior high school science teachers experienced at inquiry teaching were selected, and a semi-structured interview was conducted to collect the teachers’ perspectives on inquiry and inquiry teaching. The findings indicate that these experienced science teachers hold multiple perspectives on inquiry and inquiry teaching. The two patterns generated from these teachers’ perspectives of inquiry and inquiry teaching were systematic-based inquiry instruction and learning-based inquiry instructions. Suggestions for science teacher educators are discussed in this paper. 相似文献

In this study, I, the first author as a Thai teacher educator employed self-study as a research methodology to investigate my own understandings, questions, and curiosities about pedagogical content knowledge (PCK) for teaching science student teachers and the ways I engaged student teachers in a field-based science methods course designed to help them to develop their PCK. Qualitative data gathered included: the syllabi, handouts, work submitted by student teachers, student teachers’ journal entries, my journal entries, and video recordings of my classroom teaching. Data were analysed using an inductive process to identify ways in which I attempted to enhance student teachers’ PCK. The contributions of this study are insights generated to help teacher educators think about how to support and develop student teachers’ PCK. Some of these contributions are enhancing teacher educators’ PCK for teaching science teachers, developing PCK for teaching science, and designing a science methods course in science teacher preparation programmes. 相似文献
