Teachers play a critical role in successfully implementing science education reforms in the United States to provide high-quality science learning opportunities to all students. However, the differentiated ways in which teachers make decisions about their science teaching are not well understood. This study takes a person-centered approach by applying latent profile analysis to examine how cognitive (pedagogical content knowledge) and motivational (instructional goal orientations, self-efficacy beliefs, and reform values) characteristics combine to form science teacher profiles in middle school. Predictors of profile membership (bachelor's degree, school %FRL) and both teacher (science instructional practices) and student (science achievement, engagement, and self-efficacy) outcomes related to the teacher profiles were also examined. Five science teacher profiles were identified (severely discouraged but reform oriented, discouraged but reform oriented, conventional, confident and mastery oriented, and confident with multiple goal approaches) that represented unique configurations of cognitive and motivation characteristics. Additionally, findings showed that the teacher profiles were significantly related to three dimensions of science instructional practice including communication, discourse, and reasoning. Finally, the teacher profiles were significantly related to student science achievement and motivational outcomes. Implications for differentiated approaches to teacher professional learning and supports for science instruction are discussed.  相似文献

This investigation explores the effectiveness of a teacher preparation program aligned with situated learning theory on preservice science teachers' use of technology during their student teaching experiences. Participants included 26 preservice science teachers enrolled in a 2‐year Master of Teaching program. A specific program goal was to prepare teachers to use technology to support reform‐based science instruction. To this end, the program integrated technology instruction across five courses and situated this instruction within the context of learning and teaching science. A variety of data sources were used to characterize the participants' intentions and instructional practices, including classroom observations, lesson plans, interviews, and written reflections. Data analysis followed a constant comparative process with the goal of describing if, how, and why the participants integrated technology into their instruction and the extent to which they applied, adapted, and innovated upon what they learned in the science teacher preparation program. Results indicate that all participants used technology throughout their student teaching for reform‐based science instruction. Additionally, they used digital images, videos, animations, and simulations to teach process skills, support inquiry instruction, and to enhance student engagement in ways that represented application, adaptation, and innovation upon what they learned in the science teaching methods program. Participants cited several features of the science teacher preparation program that helped them to effectively integrate technology into their instruction. These included participating in science lessons in which technology was modeled in the context of specific instructional approaches, collaborating with peers, and opportunities for feedback and reflection after teaching lessons. The findings of this study suggest that situated learning theory may provide an effective structure for preparing preservice teachers to integrate technology in ways that support reform‐based instruction. © 2013 Wiley Periodicals, Inc.

ABSTRACT

In order to create conditions for students’ meaningful and rigorous intellectual engagement in science classrooms, it is critically important to help science teachers learn which strategies and approaches can be used best to develop students’ scientific literacy. Better understanding how science teachers’ instructional practices relate to student achievement can provide teachers with beneficial information about how to best engage their students in meaningful science learning. To address this need, this study examined the instructional practices that 99 secondary biology teachers used in their classrooms and employed regression to determine which instructional practices are predictive of students’ science achievement. Results revealed that the secondary science teachers who had well-managed classroom environments and who provided opportunities for their students to engage in student-directed investigation-related experiences were more likely to have increased student outcomes, as determined by teachers’ value-added measures. These findings suggest that attending to both generic and subject-specific aspects of science teachers’ instructional practice is important for understanding the underlying mechanisms that result in more effective science instruction in secondary classrooms. Implications about the use of these observational measures within teacher evaluation systems are discussed.  相似文献

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

This study describes the status of small school reforms in U.S. high schools and contemplates their future. It asks how cultural and instructional reforms differ across school reform types. Analyses focus on indicators of teacher and student culture as well as instructional reforms including project-based learning (PBL) and other inquiry-related practices. Findings are based on data from a national survey completed by 395 high school teachers who were responsible for and had used PBL in core academic subjects. Study participants taught in large, comprehensive high schools; in schools that had converted to small learning communities; and in newly created small school start-ups. Some of these small schools and conversions were based on a reform model, and others were not. Teachers in reform model schools reported the greatest number of cultural and instructional reforms, followed by teachers in other small schools. Reform models were particularly strong on instructional reforms and student culture. In general, start-up teachers reported more success implementing reforms than teachers in conversion schools, and teacher culture was reformed much more often than student culture and instruction. These findings help shed light on how widely practices and conditions have spread throughout the broader small schools movement, and which of these (including extensive PBL use) only seem to flourish in schools that subscribe to a holistic reform model.  相似文献

Summary Was the project successful in assisting teachers to reform their biology teaching? The answer appears to be a qualifiedyes. Although teachers changed how they taught biology, they did not necessarily adopt the model as originally conceived by the project. Teachers used materials they developed in ways that increased student involvement in learning and decreased direct teacher instruction. Teachers taught primarily from the units they developed, and they borrowed instructional ideas and lessons from other units which fit their instructional style and curriculum. Teachers did not, however, adopt complete instructional units developed by other teachers for use in their classroom.  相似文献

Reform efforts are often unsuccessful because they failed to understand that teachers play a key role in making educational reforms successful. This paper describes a long‐term teacher professional development (PD) program aimed at educating and training teachers to teach interdisciplinary topics using case‐based method in science. The research objective was to identify, follow and document the processes that science teachers went through as they assimilated the interdisciplinary, case‐based science teaching approach. The research accompanied the PD program throughout its 3‐year period. About 50 teachers, who took part in the PD program, were exposed to an interdisciplinary case‐based teaching method. The research instruments included teacher portfolios, which contained projects and reflection questionnaires, classroom observations, teacher interviews, and student feedback questionnaires. The portfolios contained the projects that the teachers had carried out during the PD program, which included case studies and accompanying student activities. We found that the teachers gradually moved from exposure to new teaching methods and subject matter, through active learning and preparing case‐based team projects, to interdisciplinary, active classroom teaching using the case studies they developed.  相似文献

This study contributes to our understanding of the complex issues inherent in dealing with the heterogeneity of current high school science classrooms, by reporting on in-depth interviews with 38 experienced biology teachers. Analyses of teachers' responses revealed complex and occasionally counter-intuitive relationships among: (a) their perceptions of what was distinctive about their school, its biology program, or their students; (b) their allocation of class time; (c) their efforts to individualize instruction and meet the needs of a heterogeneous student population; (d) their student outcome goals; and (e) the methods they used to evaluate student progress. Thus, for example, of the 9 teachers who cited the diversity of their students. 4 also commented on their poor motivation, but another 4 also commented on their high motivation. In addition, teachers reported using a similar range of instructional formats but for different reasons, depending on the characteristics of their students (e.g., cooperative learning groups used to compensate for poor attention spans, to challenge bright students, and to foster social tolerance). Discussion of these findings addresses several points of relevance for science education, teacher preparation, and curriculum reform. © 1996 John Wiley & Sons, Inc.  相似文献

Science teaching in Indonesia has undergone major reforms since independence. This paper examines the role of practical activities in secondary science from an international perspective and contrasts this with a developing country perspective. In examining major curriculum and teacher training reforms in Indonesia, continuing influences on science education from industrialised countries are acknowledged; however, nlike many other developing countries, Indonesia has essentially implemented curriculum and teacher training reforms using a pool of overseas trained senior teachers and locally trained personnel. A number of research studies on biology practical work in Indonesia suggest that practical activities in biology are more effective in enhancing student cognitive achievement, science process skills and problem solving abilities than traditional didactic classroom approaches.  相似文献

Educators have argued the need for greater attention on how teachers learn to teach writing in science (Kelly and Bazerman in Appl Linguist 24(1):28–55, 2003; Martin in Writing science: literacy and discursive power. University of Pittsburgh Press, Pittsburgh, pp 166–202, 1993). This article summarizes the findings of a qualitative study of five science preservice teachers as they experienced a unit of study, an inquiry-based instructional framework for the teaching of writing. Results found initially the science preservice teachers did not have knowledge of specific instructional approaches to teach writing. The science preservice teachers engaged in critical and analytical reading and writing, which enhanced their knowledge of writing and how to teach writing. The unit of study approach to writing may offer teacher educators a way to engage science preservice teachers in a method to teach scientific writing.  相似文献

This study examined the effects of individual student factors and classroom factors on elementary science achievement within and across five countries. The student‐level factors included gender, self‐confidence in science and home resources. The classroom‐level factors included teacher characteristics, instructional variables and classroom composition. Results for the USA and four other countries, Singapore, Japan, Australia and Scotland, were reported. Multilevel effects were examined through Hierarchical Linear Modelling, using the Trends in International Mathematics and Science Study 2003 fourth grade dataset. Overall, the results showed that selected student background characteristics were consistently related to elementary science achievement in countries investigated. At the student level, higher levels of home resources and self‐confidence and at the classroom level, higher levels of class mean home resources yielded higher science scores on the TIMSS 2003. In general, teacher and instructional variables were minimally related to science achievement. There was evidence of positive effects of teacher support in the USA and Singapore. The emphasis on science inquiry was positively related to science achievement in Singapore and negatively related in the USA and Australia. Recommendations for practice and policy were discussed.  相似文献

This article reports the influence of school-integrated teacher education (SITE) courses on student teachers' initial experiences of learning how to teach. We analyse data from five student teachers who reflect back on their experiences of learning to teach through the integrated teaching and learning experiences of SITE courses. The article presents their collective voices in poetic form to capture how they articulated their growth as teachers and their subsequent confidence in the role of teacher. We report insights into how the poem influenced 28 beginning student teachers upon entering SITE courses in their teacher education program. We analyze how this poetic representation of research findings enabled a self-study process to develop for the participants and how the poem passed on a theory of teacher development that reassures and prepares the student teachers who follow.  相似文献

The number of induction programs available to teachers is increasing rapidly, and by necessity these programs are designed to meet the needs of all teachers regardless of their preparation and academic background. This study examines the impact of a science‐focused induction program on secondary science teachers from different preparation programs. The 16 teachers were first‐year secondary science teachers who graduated the previous year from one of four different teacher‐preparation programs. All teachers were monitored during their first year of teaching, as they participated in the induction program, to understand their teaching beliefs, instructional practices, and experiences in the classroom. The analysis of data revealed that the preservice training of a science teacher influenced the type of support the teacher derived from the science‐focused induction program. Teachers from a preservice program with an extended student‐teaching experience and two science methods courses held beliefs aligned with student‐centered practices and implemented more reform‐based lessons than did other teachers during the year. This study reinforces the importance of induction programs for teachers and suggests that there is a need for specialized support programs for beginning science teachers. The study also provides specific suggestions for improving the preparation of secondary science teachers. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 963–985, 2006  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.

The need for the inclusion of socio‐scientific issues (SSI) into science curricula has been generally accepted, but relatively few science teachers have incorporated SSI into their courses. Most science teachers feel that their most important task by far is to teach the principles of science, and any substantive pedagogical changes represent a burden. Reformers and researchers often point out science teachers' lukewarm reactions to the reforms as a major barrier for educational changes but pay little attention to teachers' deeper values and inspirations. However, there are some teachers who address SSI out of their own personal initiative. Detailed case studies of four such teachers showed that although the teachers were aware of Science, Technology, Society or other reform efforts, they developed their own thrust and materials for SSI based on their own values, ideals, philosophies and personal concerns. This suggests that the current curriculum reforms (Science, Technology, Society, SSI, and Nature of Science) tend to suggest theoretical ideals, but do not effectively connect with teachers' deeper values and ideals.  相似文献

We investigate the relationship between teacher licensure test scores and student test achievement and high school course-taking. We focus on three subject/grade combinations—middle school math, ninth-grade algebra and geometry, and ninth-grade biology—and find evidence that a teacher's basic skills test scores are modestly predictive of student achievement in middle school math and highly predictive of student achievement in high school biology. A teacher's subject-specific licensure test scores are a consistent and statistically significant predictor of student achievement only in high school biology. Finally, we find little evidence that students assigned to middle school teachers with higher basic-skills test scores are more likely to take advanced math and science courses in high school.  相似文献

In England, little research has been carried out into how pre‐service secondary English teachers transform what they know as they learn to teach. They are seldom asked to reflect explicitly on the connections between the pedagogy of their undergraduate studies and their pedagogical experiences as student teachers. The initial teacher education committee of the National Association for the Teaching of English decided to explore these connections by asking student teachers on English Postgraduate Certificate in Education (PGCE) courses in five different university departments of education to respond to a series of questions at the start and end of the academic year 2004–2005. The questions fall into four broad areas: student teachers' experiences as learners at undergraduate level and developing ideas about teaching; the nature of the subject English; tensions encountered during the PGCE course; new learning about teaching. The purpose of this article is to discuss some patterns emerging from the research. The most prominent of these is student teachers' realisation that good teaching comes from teachers seeing themselves as learners. We argue that ‘reflexivity’ ( Moore, 2004 ) is a valuable way to help student teachers begin to understand this transformation from learner into learning teacher.  相似文献

In this study we sought to understand factors that shaped teachers’ use of student inquiry projects. We examined, over 3 years, the practices and conceptions of two teachers involved in implementing student inquiry projects. Neither teacher was initially satisfied with her success at supporting student inquiry, but the two had very different responses to difficulties they faced. These responses related strongly to their ideas about how learning should be structured. There was less relation between their stated views about the nature of science and their use of inquiry than was expected. The teacher with espoused views about the nature of science generally in accord with reform documents did not support student inquiry projects that involved actual investigations. The teacher with views on the nature of science less aligned with reform documents worked hard to support student investigations in her classroom. Our findings support the claim that merely learning about the nature of science or about student inquiry may not generate changes in a teacher’s practice. On closer analysis, we found that the two teachers understood aspects of the nature of science from two quite different perspectives, the proximal and the distal. The proximal view of the nature of science was more closely aligned with implementation of actual student investigations. The efforts of these two teachers in implementing inquiry illustrate the dilemmas and challenges they faced as they attempted student inquiry projects.  相似文献

Recent government reform of initial teacher education has increased teachers’ responsibility for training students in schools, bringing about some fundamental changes in the professional relationship between the schools, higher education institutions (HEIs), teachers and students. This paper reports on primary undergraduate student teachers’ and their class teachers’ perceptions of school-based training to teach art. Class teachers were interviewed about their preparedness to train students and questionnaires and interviews were used to gauge students’ views of the effectiveness of university-based courses and the support given to them by teachers. The findings indicate that teachers were able to support students in matters of classroom management and resources but that they were mostly unable to assist them in developing subject knowledge and understanding of art teaching and learning. This raises concerns about teachers’ subject knowledge and their confidence in training students. Our findings suggest that there is significant room for improvement in the partnership arrangements between schools and HEIs in order to better support students’ teaching of art.  相似文献

Despite costly global efforts to improve and reward teacher qualifications like education and experience, little international evidence exists on the relationship between these attributes and student achievement. It is also unclear whether these attributes are more important for disadvantaged children, or in lower-income countries. This article examines the relationships among teacher characteristics (experience, education, readiness to teach, and gender), student background, and fourth grade students’ mathematics and science achievement across 25 diverse countries participating in the 2003 Trends in International Mathematics and Science Study. The analysis revealed limited evidence that the teacher characteristics deemed important in teacher upgrading and compensation are systematically related to student test scores, or that these characteristics are more important for lower-income students. It also found no relationship between national income and the importance of these characteristics. These results add to increasing evidence that efforts to improve teacher quality must look beyond simply increasing and rewarding measurable teacher qualifications like education and experience. Further, those who design cross-national studies should consider developing richer measures of teacher skill and knowledge.  相似文献
