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 identifies proficiency levels in pre-service physics teachers' pedagogical content knowledge (PCK) and reveals how teacher education can promote transitions into higher proficiency. Teacher education plays a fundamental role in supporting pre-service teachers' PCK development. Proficiency levels are a powerful source when evaluating this PCK development because they characterize what learners are likely to be able to know on a specific level. Previous research has presented a model of proficiency levels in pre-service physics teachers' PCK; however, evidence for the model's validity is still lacking. According to the Refined Consensus Model of PCK, factors such as teachers' content knowledge (CK), their teaching experience, and their beliefs about teaching and learning science promote PCK development. Thus, understanding how and when pre-service physics teachers' CK, teaching experience, and beliefs contribute to their proficiency can bring insights into how teacher education can promote PCK development. To address this issue, N = 427 observations of pre-service physics teachers were analyzed. Utilizing the scale anchoring procedure, four different proficiency levels in pre-service physics teachers' PCK were identified. Analyzing these proficiency levels showed that lower levels can be characterized as remembering content-unspecific knowledge, whereas higher levels encompass content-specific strategies to structure and elaborate lessons. Additionally, logistic regression models revealed that pre-service physics teachers' CK is crucial for an increase in PCK proficiency. However, transitions into higher levels of PCK additionally require teaching experience and adequate beliefs about teaching and learning. Thus, our proficiency levels can be used to bring insights into how proficiency in PCK can be supported during teacher education. For example, teacher education should provide courses focusing on the science curriculum and the assessment of student learning to promote pre-service physics teachers' progression in PCK.  相似文献

Science textbooks are dominant influences behind most secondary science instruction but little is known about teachers' approach to science reading. The purpose of this naturalistic study was to develop and validate a Science and Reading Questionnaire to assess secondary science teachers' attitudes toward science reading and their beliefs or informed opinions about science reading. A survey of 428 British Columbia secondary science teachers was conducted and 215 science teachers responded. Results on a 12-item Likert attitude scale indicated that teachers place high value on reading as an important strategy to promote learning in science and that they generally accept responsibility for teaching content reading skills to science students. Results on a 13-item Likert belief scale indicated that science teachers generally reject the text-driven model of reading, but they usually do not have well-formulated alternative models to guide their teaching practices. Teachers have intuitive beliefs about science reading that partially agree with many research findings, but their beliefs are fragmented and particularly sketchy in regard to the cognitive and metacognitive skills required by readers to learn from science texts. The findings for attitude, belief, and total scales were substantiated by further questions in the Science and Reading Questionnaire regarding classroom practice and by individual interviews and classroom observations of a 15-teacher subsample of the questionnaire respondents.  相似文献

Teacher attitudes affect their instruction such that positive teacher attitudes enhance the teaching and learning process. The purpose of this study was to explore inservice science teachers' views of learning physics within the context of a professional development experience and to investigate the relationship between those views and the teachers' understanding of force and motion concepts. The conceptual understanding pretest results indicate the need for inservice science teacher professional development that focuses on conceptual understanding. The relationship between participants' views and their conceptual understanding at posttest has additional implications for the curriculum for these science teachers' professional development experiences.  相似文献

Response-shift bias occurs when participants' initial constructs, such as self-efficacy in teaching science, are incomplete because they do not fully conceptualize something they have yet to experience. This study examines whether elementary pre-service teachers can consistently evaluate constructs such as self-efficacy and attitudes toward science throughout an elementary methods course. After the administration of traditional pre-tests, retrospective pre-tests, and post-tests, this study examined whether a response-shift bias consistently occurred in scales indicating science teaching self-efficacy (as measured by the Science Teaching Efficacy Beliefs Instrument-B), attitudes toward science (modified Attitudes Toward Science Inventory), and relevancy of science (Changes in Attitudes about the Relevancy of Science). Results indicate that a significant response-shift bias occurred in the scales relating to self-efficacy, confidence, and attitudes toward science; while no response-shift bias occurred in scales relating to outcome expectancy, value, and relevancy of science. Our data provide evidence that response-shifts naturally discriminate among different constructs and that participants successfully and consistently reported certain constructs over time which may be of interest for program evaluators and self-efficacy researchers. This research could have implications for program evaluators and researchers who need to measure program impacts on pre-service teachers with limited science-teaching experiences.  相似文献

The purpose of this study was to describe the knowledge base of a group of science teachers in terms of their knowledge of the structure, function, and development of their disciplines, and their understanding of the nature of science. The study also aimed to relate the teachers' knowledge base to their level of education, years of teaching experience, and the class level(s) that they teach. Twenty inservice science teachers were selected to respond to a modified version of the Views on Science–Technology–Society (VOSTS) questionnaire to assess their understanding of the nature of science. The teachers then constructed concept maps and were interviewed. The concept maps were scored and the interviews analyzed to assess teachers' knowledge of the structure, function, and development of their disciplines. The teachers' knowledge base was found to be lacking in all respects. Teachers held several naive views about the nature of science and did not demonstrate adequate knowledge and understanding of the structure, function, and development of their disciplines. Moreover, the teachers' knowledge base did not relate to their years of teaching experience, the class level(s) that they teach, and their level of education. It was reasoned that teacher preparation programs are not helping teachers develop the knowledge base needed for teaching science. © 1997 John Wiley & Sons, Inc.

The Science Teachers Learning from Lesson Analysis (STeLLA) project is a videobased analysis‐of‐practice PD program aimed at improving teacher and student learning at the upper elementary level. The PD program developed and utilized two “lenses,” a Science Content Storyline Lens and a Student Thinking Lens, to help teachers analyze science teaching and learning and to improve teaching practices in this year‐long program. Participants included 48 teachers (n = 32 experimental, n = 16 control) and 1,490 students. The STeLLA program significantly improved teachers' science content knowledge and their ability to analyze science teaching. Notably, the STeLLA teachers further increased their classroom use of science teaching strategies associated with both lenses while their students increased their science content knowledge. Multi‐level HLM analyses linked higher average gains in student learning with teachers' science content knowledge, teachers' pedagogical content knowledge about student thinking, and teaching practices aimed at improving the coherence of the science content storyline. This paper highlights the importance of the science content storyline in the STeLLA program and discusses its potential significance in science teaching and professional development more broadly. © 2011 Wiley Periodicals, Inc., J Res Sci Teach 48: 117–148, 2011  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

This study investigated Emirates pre-service and in-service teachers' views about the nature of science. A questionnaire was developed and administered to 31 female pre-service science teachers, and 224 inservice chemistry teachers. The questionnaire covered five aspects of the nature of science identified by Palmquist and Finley (1997). These are: scientific theories and models; role of a scientist; scientific knowledge; scientific method; and scientific laws. The results indicated that Emirates teachers' views are neither clearly traditional nor clearly constructivist - they held mixed views about the nature of science. The study attributed the existence of the traditional views to historical reasons and the educational system. The presence of constructivist views was attributed to religious factors, where some of students' religious beliefs agree with some constructivist views. The study argued that the traditional view about the nature of science is in conflict with the teachers' religious beliefs. Teaching science in the Arab culture using the traditional view about science creates what Tobin (1996) called 'symbolic violence'. The study concluded that introducing science from the constructivist point of view and using what Jegede (1996) called 'collateral learning' would help to diminish such violence.  相似文献

This paper reports on a 4-year longitudinal case study of two Australian primary science teachers during their transition from pre-service to in-service teaching. An analytic framework suggested by Aikenhead (1996) was used to interpret teachers' change and professional growth as instances of sub-cultural border crossing. The same framework provides an opportunity for reflexivity on the part of the researchers in coming to understand their own role in the construction of the borders crossed by beginning teachers. The study examines the hazards encountered by teachers as they cross borders and proposes ways of assisting teachers to manage border crossing into the sub-culture of science teaching.  相似文献

Background This paper compares the findings from a recent, large-scale UK-wide survey of primary teachers' confidence in teaching science with the results of a seminal report carried out 10 years ago by Wynne Harlen in Scotland. Recent reports from across the UK have indicated there are still serious concerns relating to primary teachers' confidence and ability to teach science effectively.

Purpose The main research aims were to provide a clear, evidence-based analysis of the current issues facing primary science in the UK; explore primary teachers' confidence in science teaching and to evaluate the impact of science initiatives taking place in UK primary schools.

Sample The sample for the study comprised: telephone interviews with 300 primary teachers from all UK regions; seven focus groups of primary teachers held in England, Northern Ireland, Scotland and Wales to further explore the issues raised in the telephone interviews; and workshops from a two-day conference of 75 stakeholders in primary science from all UK regions (approximately half the delegates were teachers; also represented were teacher educators (initial and continuing professional development), curriculum developers and policy-makers). In addition, 100 teacher education institutions were surveyed in relation to their participation in primary science initiatives.

Design and methods The methodology for both studies comprised qualitative and quantitative elements (see sample details, above). All data were collected between June and September 2004.

Results The findings indicated that there are improvements in some areas of primary teachers' confidence in teaching science. However, the study showed that half of the teachers surveyed cited lack of teacher confidence and ability to teach science as the current issue of major concern in primary science. This paper also reports on some of the professional development initiatives carried out by higher education institutions in primary science.

Conclusions The paper concludes that there has been some progress in developing teacher confidence in primary science over the past 10 years. However, the situation is still critical for all stakeholders. Half of the teachers surveyed in the UK for the present study identified lack of teacher confidence and ability to teach science as the major issue of concern in primary science. Higher education institutions need to enhance the preparation of new primary teachers to ensure that they are all confident and effective teachers of science. They could also increase their partnership work with schools and other continuing professional development (CPD) providers in relation to primary science. The evidence demonstrates clearly that there is a need for substantially increasing science professional development for primary teachers. It also shows that such professional development could be more effectively targeted at specific aspects of science teaching that are more challenging for teachers. Further, the study shows that professional development in science works, in that teachers who have experienced science continuing professional development (CPD) are much more confident to teach science than those who have not.  相似文献

This study investigated the effect of problem posing on the pre-service primary teachers' understanding of fraction concepts enrolled in two different versions of a methods course at a university in Turkey. In the experimental version, problem posing was used as a teaching strategy. At the beginning of the study, the pre-service teachers' knowledge of symbols and algorithms was adequate in both groups, but they were unable to provide appropriate representations and explanations for the given fraction situations. Results showed that problem posing had a positive impact on the pre-service teachers' knowledge and views about what it means to know mathematics.  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

The purpose of this cross-case analysis is to illustrate how and why literacy was incorporated into science teaching and learning in three secondary classrooms. Research questions guiding the analysis include: (a) How were literacy events shaped by the teachers' philosophies about teaching science content and teaching students? and (b) How was literacy (reading, writing, and oral language) structured by the teachers and manifested in science lessons? The methodology of ethnography and the theoretical framework of symbolic interactionism were employed in the three studies on which the cross-case analysis was based. The researchers assumed the role of participant observers, collecting data over the period of 1 year in each of the three classrooms. Data, in the form of fieldnotes, interviews, and artifacts, were collected. In each study, data were analyzed using the constant comparative method (Glaser & Strauss, 1967) to determine patterns in the teachers' beliefs about learning and how these influenced their choice of literacy activities. The cross-case analysis was conducted to determine patterns across the three teachers and their classrooms. The findings from this analysis are used to compare how the teachers' philosophies of teaching science and their beliefs about how students learn influenced their use of literacy practices during lessons. Specifically, each teacher's use of literacy activities varied based on his or her beliefs about teaching science concepts. Furthermore, reading, writing, and oral language were important vehicles to learning science concepts within daily classroom activities in the three classrooms.  相似文献

An in-depth case study of teachers' use of image processing (a state-of-the-art computer technology used by research scientists) in biology, earth science, and physics classes within one high school science department explored issues surrounding technology implementation. The study, conducted within a districtwide, schoolwide, and classroom context, explored four areas related to the teacher's adoption of image processing: (a) teachers' background with computers outside of instructional use, (b) teachers' attitudes toward educational technology and insights gained from their experience using computers within the science curriculum, (c) training and perceived influence of district and school administrators, and (d) teachers' classroom and computer lab practices. The following factors were deemed critical in teachers' decision to use or not use image processing with their students: (a) time to thoroughly explore and master the technology so they could use it with students to explore science concepts; (b) classroom management skills specific to technology use; (c) perception of the teaching value of the technology; (d) perception of the reasonableness of administrators' expectations for technology use; and (e) understanding of how to implement inquiry-based science teaching, independent of technology issues. These factors have implications for how to help teachers use computer technology to teach high school science. © 1998 John Wiley & Sons, Inc. J Res Sci Teach 35: 297–327, 1998.  相似文献

Studies suggest that pre-service teachers' existing beliefs often serve as a lens to interpret the subject matter to be taught, guide their thoughts in lesson planning and shape their behaviour in classroom practices during their teaching practicum. This study examines how these beliefs affect pre-service teachers' conceptualization of Putonghua-medium-of-instruction (PMI) and their teaching. The findings indicate that the conceptualization of pre-service teachers about PMI ranged from code switching to curriculum integration. Their focus of lesson planning and teaching practice varied from transmission of Putonghua knowledge and detailed explanation of text information to integration of Chinese Language and Putonghua.  相似文献

In this article, we focus on the contributions that a simulated jury-based activity might have for pre-service teachers, especially for their active participation and learning in teacher education. We observed a teacher educator using a series of simulated juries as teaching resources to help pre-service teachers develop their pedagogical knowledge and their argumentation abilities in a physics teacher methods course. For the purposes of this article, we have selected one simulated jury-based activity, comprising two opposed groups of pre-service teachers that presented aspects that hinder the teachers' development of professional knowledge (against group) and aspects that allow this development (favor group). After the groups’ presentations, a group of judges was formed to evaluate the discussion. We applied a multi-level method for discourse analysis and the results showed that (1) the simulated jury afforded the pre-service teachers to position themselves as active knowledge producers; (2) the teacher acted as ‘animator' of the pre-service teachers' actions, showing responsiveness to the emergence of circumstantial teaching and learning opportunities and (3) the simulated jury culminated in the judges’ identification of the pattern ‘concrete/obstacles–ideological/possibilities' in the groups’ responses, which was elaborated by the teacher for the whole class. Implications from this study include using simulated juries for teaching and learning and for the development of the pre-service teachers’ argumentative abilities. The potential of simulated juries to improve teaching and learning needs to be further explored in order to inform the uses and reflections of this resource in science education.  相似文献

This study investigated changes in pre-service teachers' personal epistemologies as they engaged in an integrated teaching program. Personal epistemology refers to individual beliefs about the nature of knowing and knowledge and has been shown to influence teaching practice. An integrated approach to teaching, based on both an implicit and explicit focus on personal epistemology, was developed by an academic team within a Bachelor of Education (Early Childhood). The teaching program integrated content across four units of study, modelling personal epistemologies implicitly through collaborative reflexive practice. The students were also required to engage in explicit reflections on their personal epistemologies. Quantitative measures of personal epistemology were collected at the beginning and end of the semester using the Epistemological Beliefs Survey (EBS) to assess changes across the teaching period. Results indicated that pre-service teachers' epistemological beliefs about the integration of knowledge became more sophisticated over the course of the teaching period. Qualitative data included pre-service teachers' responses to open ended questions and field experience journal reflections about their perceptions of the teaching program and were collected at the end of the semester. These data showed that pre-service teachers held different conceptions about learning as integration, which provided a more nuanced understanding of the EBS data. Understanding pre-service teachers' epistemological beliefs provides promising directions for teacher preparation and professional enrichment.  相似文献

ABSTRACT

The authors find justification for integrating science, technology, engineering, and mathematics (STEM) in the complex problems that today's students will face as tomorrow's STEM professionals. Teachers with individual subject-area specialties in the STEM content areas have limited experience in integrating STEM. In this study, the authors investigated the conceptual changes of secondary school teachers teaching domain-specific STEM courses after a week-long professional development experience integrating earthquake engineering and domain-specific concepts. They documented and then triangulated outcomes of the experience using participating teachers' concept maps and teacher-generated written materials, respectively. Statistical comparisons of participants' concept maps revealed significant increases in their overall understanding of earthquake engineering and more accurate linkages with and among science domain-specific concepts. Content analyses of teachers' learning products confirmed the concept map analysis and also provided evidence of transfer of workshop learning experiences into teacher-designed curriculum products accurately linking earthquake engineering and domain-specific STEM content knowledge.  相似文献

In this article, we present a valid and reliable instrument which measures the attitude of in-service and pre-service primary teachers toward teaching science, called the Dimensions of Attitude Toward Science (DAS) Instrument. Attention to the attitudes of primary teachers toward teaching science is of fundamental importance to the professionalization of these teachers in the field of primary science education. With the development of this instrument, we sought to fulfill the need for a statistically and theoretically valid and reliable instrument to measure pre-service and in-service teachers' attitudes. The DAS Instrument is based on a comprehensive theoretical framework for attitude toward (teaching) science. After pilot testing, the DAS was revised and subsequently validated using a large group of respondents (pre-service and in-service primary teachers) (N = 556). The theoretical underpinning of the DAS combined with the statistical data indicate that the DAS possesses good construct validity and that it proves to be a promising instrument that can be utilized for research purposes, and also as a teacher training and coaching tool. This instrument can therefore make a valuable contribution to progress within the field of science education.  相似文献
