Abstract This article examines the social nature of teachers' conceptions by showing how teachers frame the “mismatch” of students' perceived abilities and the intended school curriculum through conversational category systems. This study compares the conversations of 2 groups of high school mathematics teachers addressing the Mismatch Problem when implementing equity-geared reforms. Although East High teachers challenged conceptions that were not aligned with a reform, South High teachers reworked a reform mandate to align with their existing conceptions. This research found that the teachers' conversational category systems modeled problems of practice; communicated assumptions about students, subject, and teaching; and were ultimately reflected in the curriculum. Because East High teachers supported greater numbers of students' success in advanced mathematics, this study considers the relation between teachers' understandings of student learning and the success of equity-geared math reforms. In addition, this study contributes to the understanding of how teacher conceptions of students are negotiated and reified in context, specifically through interactions with colleagues and experiences with school reform. 相似文献

The purpose of this study was to investigate the beliefs of six experienced high school science teachers about (1) what is successful science learning; (2) what are the purposes of laboratory in science teaching; and (3) how inquiry is implemented in the classroom. An interpretive multiple case study with an ethnographic orientation was used. The teachers' beliefs about successful science learning were substantively linked to their beliefs about laboratory and inquiry implementation. For example, two teachers who believed that successful science learning was deep conceptual understanding, used verification labs primarily to illustrate these concepts and used inquiry as a type of isolated problem‐solving experience. Another teacher who believed that successful science learning was enculturation into scientific practices used inquiry‐based labs extensively to teach the practices of science. Tension in competing beliefs sets and implications for reform are discussed. ? 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 936‐960, 2004. 相似文献

As part of a larger project aimed at promoting science and literacy for culturally and linguistically diverse elementary students, this study has two objectives: (a) to describe teachers' initial beliefs and practices about inquiry‐based science and (b) to examine the impact of the professional development intervention (primarily through instructional units and teacher workshops) on teachers' beliefs and practices related to inquiry‐based science. The research involved 53 third‐ and fourth‐grade teachers at six elementary schools in a large urban school district. At the end of the school year, teachers reported enhanced knowledge of science content and stronger beliefs about the importance of science instruction with diverse student groups, although their actual practices did not change significantly. Based on the results of this first year of implementation as part of a 3‐year longitudinal design, implications for professional development and further research are discussed. © 2004 Wiley Periodicals, Inc.

In this research project, we investigated two beginning secondary science teachers' efforts to learn to teach science in ways that build from and celebrate the ethnic, gender, linguistic, and academic diversity of their students. To do so, we followed Troy and Brian from their preservice teacher education experiences through their first year of teaching 8th grade physical science at local junior high schools. We also conducted a follow‐up observation and interview with each participant after he had moved past the beginning stage of survival in the teaching profession—once in his fourth year of public school science teaching. Through qualitative analysis of interviews, classroom observations, and teachers' written work, we identified patterns and explored commonalities and differences in Troy and Brian's views and practices tied to equity over time. In particular, we examined successes and challenges they encountered in learning to teach science for all (a) from their students, (b) from inquiry into practice, and (c) from participation in professional communities. In our implications, we suggest ways teacher educators and induction professionals can better support beginning teachers in learning to teach science to all students. In particular, we highlight the central roles both individual colleagues and collective school cultures play in aiding or impeding beginning teachers' efforts to learn from students, from practice, and from professional communities. © 2006 Wiley Periodicals, Inc.

This study continues research previously conducted by a nine‐university collaborative, the Salish I Research Project, by exploring science teachers' beliefs and practices with regard to inquiry‐oriented instruction. In this study, we analyzed the relationship among secondary science teachers' preparation, their beliefs, and their classroom practices after completion of a course designed to provide authentic inquiry experiences. From Teacher Pedagogical Philosophy Interview data and Secondary Science Teacher Analysis Matrix observational data, we analyzed links between the teachers' conveyed beliefs and observed practice regarding the teachers' actions (TA) and students' actions (SA). Also presented is a listing of teachers' perceived influences from university preparation course work. Results indicated that 7 of the 8 teachers professed a belief in teacher‐centered or conceptual style with regard to TA and SA. The observational results indicated that 7 of the 8 teachers displayed a teacher‐centered or conceptual style with regard to TA and SA. Inconsistencies between interview and observational data were unexpected, as half of the teachers professed slightly greater teacher‐centered styles with regard to TA than what they actually practiced in their classrooms. All teachers reported that an inquiry‐based science course was valuable. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 938–962, 2006 相似文献

The current reform movement in science education promotes standards‐based teaching, including the use of inquiry, problem solving, and open‐ended questioning, to improve student achievement. This study examines the influence of standards‐based teaching practices on the achievement of urban, African‐American, middle school science students. Science classes of teachers who had participated in the professional development (n = 8) of Ohio's statewide systemic initiative (SSI) were matched with classes of teachers (n = 10) who had not participated. Data were gathered using group‐administered questionnaires and achievement tests that were specifically designed for Ohio's SSI. Analyses indicate that teachers who frequently used standards‐based teaching practices positively influenced urban, African‐American students' science achievement and attitudes, especially for boys. Additionally, teachers' involvement in the SSI's professional development was positively related to the reported use of standards‐based teaching practices in the classroom. The findings support the efficacy of high‐quality professional development to change teaching practices and to enhance student learning. © 2000 John Wiley & Sons, Inc.

The purpose of this qualitative case study was to explore what aspects of two first‐year elementary teachers' practices were most consistent with an inquiry‐based approach, what PCK served as a mechanism for facilitating these practices, and what experiences have mediated the nature and development of these teachers' PCK. For each of the participants data included audio‐recorded interviews, video‐recorded classroom observations, lesson plans, and samples of student work. Data analysis illustrated that both participants engaged their students in question‐driven investigations, the use of observational data, making connections between evidence and claims, and communicating those claims to others. Moreover, there was clear evidence in the findings of the study that a considerable degree of coherence existed between the two participants' knowledge on one hand and their instructional practices on the other hand. The participants perceived specific learning experiences during their programs as being critical to their development. The contribution of this study lies in the fact that it provides examples of well‐started beginning elementary teachers implementing inquiry‐based science in 2nd and 5th grade classrooms. Implications of the study include the need for the design of university‐based courses and interventions by which teacher preparation and professional development programs support teachers in developing PCK for scientific inquiry and enacting instructional practices that are congruent with reform initiatives. © 2010 Wiley Periodicals, 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

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

AbstractIn this study, we examined a group of four teachers who completed extra educational technology coursework and field experiences during their teacher education programs to determine how their technology integration knowledge, self-efficacy beliefs, intentions, and practices evolved over time. We conducted interviews and evaluated data sources at three intervals: (1) after teacher education coursework was completed, (2) after student teaching was completed, and (3) after two initial years of teaching. Results showed that school resources and environment had a strong impact on beginning teachers' practices, regardless of strong internal enabling factors. 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

This study examined Chinese and US middle-school science teachers' perceptions of autonomy support. Previous research has documented the link between teachers' perceptions of autonomy and the use of student-oriented teaching practices for US teachers. But is not clear how the perception of autonomy may differ for teachers from different cultures or more specifically how motivation factors differ across cultures. The survey measured teachers' motivation, perceptions of constraints at work, perceptions of students' motivation, and level of autonomy support for students. Exploratory factor analysis of responses for the combined teacher sample (n?=?201) was carried out for each of the survey assessments. Significance testing for Chinese (n?=?107) and US (n?=?94) teachers revealed significant differences in teachers' motivation and perceptions of constraints at work and no significant differences for perceptions of students' motivation or their level of autonomy support for students. Chinese teachers' perceptions of constraints at work, work motivation, and perceptions of student motivation were found to significantly predict teachers' autonomy support. For the US teachers, teacher motivation was the only significant predictor of teachers' autonomy support. A sub-sample of teachers (n?=?19) was interviewed and results showed that teachers in both countries reported that autonomy was important to their motivation and the quality of science instruction they provided to students. The primary constraints on teaching reported by the US teachers related to materials and laboratory space while the Chinese teachers reported constraints related to the science curriculum and standards. 相似文献

The teachers' role in the integration of science and technology studies within the recent educational reform in Israeli junior high schools was addressed within a case study. Eight science teachers and three technology teachers participated in in‐service training courses and received individual tutoring. Data were obtained through school visits, interviews with management, teachers, and tutors. Pupils' performance on a science‐technology project was assessed by an achievement test and a questionnaire. Science teachers preferred to extend their content knowledge and didactic skills in science. Technology teachers lacked basic scientific knowledge. A realistic aim is to expose the science teacher to the field of technology, and the technology teacher to the realm of science, to the extent that will enable him or her to cooperate with the teacher in the parallel domain, rather than train a teacher to teach both. © 1999 John Wiley & Sons, Inc.

This conceptual article examines the influence of the current standards‐based reform upon science education policies and practices within urban schools. We identify four negative yet unforeseen effects of the reform movement: undermining urban teachers' professionalism, eroding teacher–student relationships, diluting the science curriculum, and disparate instruction based on predicted individual test performance. Our awareness of these nuisances emerged from our first‐hand engagement with urban science teaching and through our collegial relationships with exemplary urban teachers. In closing, we propose mechanisms by which university‐based science educators might address these issues by assisting exemplary urban teachers to resist the reform‐induced perils and by incorporating the urban milieu as a substantive aspect of science teacher education. © 2002 John Wiley & Sons, Inc.

Exploring teachers' informal formative assessment practices and students' understanding in the context of scientific inquiry 总被引：1，自引：0，他引：1
This study explores teachers' informal formative assessment practices in three middle school science classrooms. We present a model for examining these practices based on three components of formative assessment (e liciting, r ecognizing, and u sing information) and the three domains linked to scientific inquiry (epistemic frameworks, conceptual structures, and social processes). We describe the informal assessment practices as ESRU cycles—the teacher E licits a question; the S tudent responds; the teacher R ecognizes the student's response; and then U ses the information collected to support student learning. By tracking the strategies teachers used in terms of ESRU cycles, we were able to capture differences in assessment practices across the three teachers during the implementation of four investigations of a physical science unit on buoyancy. Furthermore, based on information collected in a three‐question embedded assessment administered to assess students' learning, we linked students' level of performance to the teachers' informal assessment practices. We found that the teacher who more frequently used complete ESRU cycles had students with higher performance on the embedded assessment as compared with the other two teachers. We conclude that the ESRU model is a useful way of capturing differences in teachers' informal assessment practices. Furthermore, the study suggests that effective informal formative assessment practices may be associated with student learning in scientific inquiry classrooms. © 2006 Wiley Periodicals, Inc.

This study further extends a conceptual framework that explores science teaching as a “practice” not reducible to the application of formal knowledge, but as informed by teachers' practical‐moral knowledge. A hermeneutic model was developed to examine practical‐moral knowledge indirectly by investigating teachers' commitments, interpretations, actions, and dialectic interactions between them. The study also aimed to analyze teachers' actions in terms of their interpretations and commitments as they realize “internal goods” of their practice. Ethnographic case studies of three science teachers were conducted through classroom observation, in‐depth interviews and dialogues, and artifact analysis. A commitment of preparing students for national exams was common to the three teachers but was manifested differently in classroom practices. This commitment originated from interpretations about the duty of “good” teachers not letting students and schools down. Other emergent commitments were commitments: to conceptual understandings, to “challenge” learners, and to social modeling. We present each with associated interpretations and actions. The concepts of practical wisdom (phronesis) and gap closing are used to characterize teachers' practical knowledge and its development respectively. Implications for teacher education are discussed. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 929–951, 2010 相似文献

Turkish science teachers' in‐service needs and the effects of teacher and school demographic variables on these needs are examined in this study. In addition, major barriers that prevented science teachers from attending in‐service programmes are investigated. The data for the research were gathered through a survey. This study shows that Turkish science teachers require more instructional materials, laboratory equipment, computers, and software and need in‐service education to integrate these instructional facilities into their lessons. This study also indicates that teacher and school demographic variables have little significance in predicting science teachers' needs. 相似文献
