This research examines factors influencing elementary science teacher learning as they participate in professional development with and enactment of educative curricula in comparison with learning following limited professional development and enactment of traditional curricula. Using a randomized cluster design (125 teachers and 2,694 students in 4th—5th grades) that met the What Works Clearinghouse standards without reservations, teacher learning was conceptualized using four outcomes. Data were analyzed using standard single-level multiple regression models and possible mediation models for the teacher outcomes were considered using piecewise multiple regression and path analytic approaches. Treatment group teachers experienced greater increases in content knowledge, views of science inquiry, beliefs about reform-based teaching, and teaching self-efficacy than comparison group teachers. The findings indicate that what teachers learn from the combination of professional development and teaching with educative curriculum varies according to what their knowledge and beliefs are on entering the experience. Surprisingly, high entry-level self-efficacy was associated not only with lower learning gains for the teachers, but also for their students. Finally, teachers' space science learning and that of their students are implicated as mediators of the positive effect of the professional development and educative curriculum enactment on teacher beliefs about reform science teaching. This work refines and extends a theoretical framework of teachers' participatory relationship with curricula.  相似文献

We present results of an experimental study of an urban, museum-based science teacher PD programme. A total of 125 teachers and 1676 of their students in grades 4–8 were tested at the beginning and end of the school year in which the PD programme took place. Teachers and students were assessed on subject content knowledge and attitudes towards science, along with teacher classroom behaviour. Subject content questions were mostly taken from standardised state tests and literature, with an ‘Explain:’ prompt added to some items. Teachers in the treatment group showed a 7% gain in subject content knowledge over the control group. Students of teachers in the treatment group showed a 4% gain in subject content knowledge over the control group on multiple-choice items and an 11% gain on the constructed response items. There was no overall change in science attitudes of teachers or students over the control groups but we did find differences in teachers’ reported self-efficacy and teaching anxiety levels, plus PD teachers reported doing more student-centered science teaching activities than the control group. All teachers came into the PD with high initial excitement, perhaps reflecting its context within an informal learning environment.  相似文献

This study had two purposes: to explore the components of the pedagogical content knowledge (PCK) of an experienced elementary science teacher and to reveal the presumed interactions among these components. A naturalistic inquiry was conducted as a single case study in which in-depth qualitative data were gathered through semi-structured interview questions. After the theory-based and data-driven analysis of the qualitative data, the verbal communication was quantitated into numerical data for the enumerative analysis. The results revealed that the teacher’s knowledge of students’ understanding and difficulties, knowledge of the elementary science curriculum and knowledge of instructional strategies and representations were found to be mostly intersected PCK components, whereas orientations towards teaching science and knowledge of assessment in science had limited connections to the other components. Further discussions and context-based suggestions are given regarding professional development programmes.  相似文献

We present an inquiry‐based, aquatic science professional development (PD) for upper‐elementary, middle, and high school teachers and examine changes in student outcomes in light of participating teachers’ characteristics and the grade band of the students. Our study lends support to the assertion that inquiry‐ and content‐focused PD, paired with classroom implementation, can effectively improve student learning. Our findings indicate that students improved in their nature of science (NOS) and aquatic science content knowledge and that these changes depended in some ways on the participating teachers’ characteristics and adherence to the program. The students’ improvements were amplified when their teachers adhered more closely to the PD activities during their classroom implementation. The teachers’ previous science PD experience and pre‐PD understanding of inquiry‐based teaching also explained some of the variability in student growth. In both NOS and content, students of teachers with less prior science‐PD experience benefited more. Grade band also explained variation in student outcomes through interactions with teacher‐characteristic variables. In high school, students of teachers with lower pre‐PD inquiry knowledge appeared to learn more about NOS. Our results suggest that inquiry and content training through PD may minimize disparities in teaching due to inexperience and lack of expertise. Our study also demonstrates the value of PD that teaches a flexible approach to inquiry and focuses on underrepresented, interdisciplinary content areas, like aquatic science. © 2017 Wiley Periodicals, Inc.

A recent framework on nature of science (NOS) is the Family Resemblance Approach (FRA). FRA presents NOS as a cognitive-epistemic and social-institutional system with a set of categories: aims and values, scientific methods, scientific practices, scientific knowledge and social-institutional aspects of science. Although FRA has been problematised philosophically and its implications for science education have been considered by science educators, its empirical adaptations in science education are limited. In order to illustrate the educational adaptations of FRA, we refer to Reconceptualised Family Resemblance Approach to Nature of Science or RFN. We present a study based on a funded pre-service science teacher education project whose aim was to design, implement and evaluate the impact of RFN strategies. Fifteen pre-service teachers participated in a 14-week teacher education intervention that infused RFN. A 70-item questionnaire was designed to investigate the outcomes of the teacher education intervention. Individual interviews with pre-service teachers were also conducted. Quantitative and qualitative data analysis suggest that the teacher education intervention had an overall significant impact on pre-service teachers’ views of NOS. The paper contributes to the understanding of how NOS can be incorporated in science teacher education using a new orientation to NOS based on FRA.  相似文献

In this study, a sociocultural perspective was adopted to understand the interplay between identity and agency in a context of science education reform in China. The manifestation of agency and the interaction between identity and agency were examined with two beginning science teachers teaching with practical work in high school. As part of this study, the identity formation of beginning science teachers was conceived as a site for locating and investigating teacher agency. Based on multiple data sources, we identified six spaces in which the two participants’ agency manifested: (1) personal characteristics; (2) personal beliefs; (3) interactions with students; (4) interactions with colleagues; (5) curriculum materials; and (6) high-stakes examinations. In each space, the two participants’ agency contrasted in terms of perspectives and actions: one was passive, less confident and negative, whereas the other active, more confident and positive. Moreover, it was found that their contrary actions were the result of different perspectives. Based on the findings, a model of the interplay between the identity and agency of an individual science teacher is proposed in a context of curriculum reform. The implications of this model for future research and science teacher development are discussed.  相似文献

This review provides an overview of the the current state of research on professional development in science education. An analytical frame was used, based on what is known about PD from educational research. Clarke and Hollingsworth’s model for teacher professional growth was also used to categorise the studies according to their aims and outcomes. Exemplar studies in each category are highlighted. In total, 44 recent studies were selected, all referring to science PD. The results show an increase in the number of PD studies in science education in recent years. Most PD programmes are aimed at enhancing teacher cognitions as well as classroom practice. Most recently, there seems to have been an increase in programmes that also aim at improving student outcomes through PD. All studies applied most of the characteristics drawn from research on what makes PD effective. However, school organisational conditions were not usually taken into account. Moreover, there has been a very little research on the role of facilitators and their impact on the outcomes of a PD programme.  相似文献

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

Reform based curriculum offer a promising avenue to support greater student achievement in science. Yet teachers frequently adapt innovative curriculum when they use them in their own classrooms. In this study, we examine how 19 teachers adapted an inquiry‐oriented middle school science curriculum. Specifically, we investigate how teachers' curricular adaptations (amount of time, level of completion, and activity structures), teacher self‐efficacy (teacher comfort and student understanding), and teacher experience enacting the unit influenced student learning. Data sources included curriculum surveys, videotape observations of focal teachers, and pre‐ and post‐tests from 1,234 students. Our analyses using hierarchical linear modeling found that 38% of the variance in student gain scores occurred between teachers. Two variables significantly predicted student learning: teacher experience and activity structure. Teachers who had previously taught the inquiry‐oriented curriculum had greater student gains. For activity structure, students who completed investigations themselves had greater learning gains compared to students in classrooms who observed their teacher completing the investigations as demonstrations. These findings suggest that it can take time for teachers to effectively use innovative science curriculum. Furthermore, this study provides evidence for the importance of having students actively engaging in inquiry investigations to develop understandings of key science concepts. © 2010 Wiley Periodicals, Inc., J Res Sci Teach 48: 149–169, 2011  相似文献

Internationally, considerable reform in science education is occurring which promotes constructivist philosophies and advocates constructivist-inspired pedagogical strategies that are new to many teachers. This paper reports on the supporting factors necessary for teacher professional growth and the issues of concern that were evident during one primary teacher's successful implementation of a unit of work based on a draft of a new state-wide science syllabus which proposes such approaches. One researcher (CEP) provided guidance during the writing and implementation of the unit through professional development workshops complemented by ongoing collegial support. The analysis of the teacher's practice reveals that professional growth required a willingness of the teacher to engage with change and modify his professional practice. The support factors for teacher growth consisted of an appropriate program of professional development, teacher understanding of the elements of the curriculum innovation, and successful experiences in implementing new approaches. In contrast, the issues of concern were: the adequacy of support for planning including the time required to understand the innovation and make changes to teaching practice; science equipment; teacher knowledge; classroom management strategies; and ways to cope with change. Understanding of these support factors and issues of concern is vital for the successful implementation of science curriculum innovations.  相似文献

This study examined the processes of change in thinking as a means of learning about the professional development of two science teacher educators. A qualitative methodology was used. The main research tool was a semistructured in‐depth interview. The primary data analyzed came from two science teacher educators, selected from a broader set of seven. Findings emphasize the importance of questions regarding the knowledge possessed by teacher educators and of the questions regarding the role of science teacher educators. That is, the knowledge of an expert science teacher educator was more than a list of givens; it was personal and context‐bound. This study contributes new insight into the processes of teacher educators' professional development and change in their thinking. © 2007 Wiley Periodicals, Inc.

Thirty-five elementary teachers participated in a yearlong professional development (PD) program that was designed to foster a culture of on-going teacher learning to promote the co-development of science and language literacy for English language learners (ELL). An explanatory design methodology was used to determine the degree to which science and language literacy co-developed. The research question guiding this study was: In what ways did the yearlong PD science program support teachers at 10 elementary schools to become more knowledgeable about fostering science literacy and its role in co-developing language literacy (e.g. reading, writing, listening, and speaking) for ELL? The measurable and significant gains on the quantitative mandated state science and reading tests and the analysis of qualitative teaching episodes led to the conclusion that demonstrated the synergy between science learning and language learning – as one increased, so did the other.  相似文献

An important task for the preschool teacher is to create meaningful learning situations where children have opportunities to experience science. However, many teachers have both weak subject knowledge and a lack of confidence to teach science. The aim of the project presented in this article was to capture how nine preschool teachers developed their learning of and self-confidence in teaching science during a two-year professional development (PD) project while coplanning, coteaching, and coreflecting on their teaching activities. During the project, the preschool teachers’ self-confidence and attitudes played an important role for the their approach to science activities. Their collaborative learning and reflection became important for their PD and for the way science phenomena were included in the preschool context. As such, the project is based on opportunities for preschool teachers to develop their ideas about science and to reframe their work with the aim to stimulate children’s curiosity for science.  相似文献

Background and purpose: To date, there has been little research on the Teacher Professional Development (TPD) for delivering a mobile technology-supported science curriculum. To address this, a TPD model for a science curriculum supported by mobile technology was developed and evaluated in this paper. The study reported focuses on the establishment of the TPD model and exploration of its impact on teacher behaviors in the curriculum implementation.

Sample, design, and methods: In the study, two representative science teachers’ implementation of the science curriculum was presented together with an in-depth study of the TPD sessions. The data from the teacher-led PD working sessions, classroom observation and teacher interview were collected. Mixed methods and case study were used to analyze the teacher performance on the PD working sessions and on the curriculum implementation.

Results: Our findings suggested that teachers benefited from the structured TPD which provided opportunities for sharing, extensive feedback, and reflection of the curriculum implementation. It showed that teachers had transformed questioning from traditional ways into constructivist-oriented patterns in the classroom. More student-centered activities were conducted and complemented with teachers’ various scaffolds for learning. Analysis of learning artifacts attested to improvements in students’ conceptual understanding of science.

Conclusion: TPD refers to a continuing and dynamic system for PD which needs to be changed and elaborated based on teacher needs, school context and the problems and challenges encountered in the teaching practice. TPD development and teachers’ growth in the belief and competences on the instruction constitute a mutual evolution process. Their evolution could guarantee the apt enactment and spread of the curriculum innovation to impact depth, to sustain and to spread.  相似文献

Over the past 10?years an increasing number of articles have been published in leading science education journals that report on research about teacher identity and describe interventions that support teacher identity development. My purpose in this review paper is to examine how the construct of science teacher identity has been conceptualised and studied in science education. In doing so, I synthesise the findings of 29 empirical studies on teacher identity within the field of science education in an attempt to respond to the following questions: (a) In what ways have researchers used the construct of teacher identity to examine science teacher learning and development? (b) What approaches to supporting science teacher identity development have been documented in the literature? Following that, I identify gaps and limitations in the existing literature and I offer recommendations for future research in the area of science teacher identity and identity development: (a) studying teacher identity as a process; (b) connecting science teacher identity research and reform recommendations; (c) conducting large-scale, longitudinal and life-history studies; and (d) examining teacher identity enactment in school classrooms.  相似文献

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

In this article we review the notion of teacher knowledge from four metaphorical standpoints – teacher knowledge as computer, as craft, as complexity and as change. We employ each of these metaphors to examine and analyse the work of one teacher of science. We draw implications from our analysis for teacher education, teacher development and the study of teaching.  相似文献

This paper describes the current state of science education in Arab states and anticipates some of the challenges faced by those states as they reform their science education. After discussing problems of illiteracy, access and quality we provide contextual information about the structure of the educational systems and describe recent efforts to reform them. We focus on issues pertaining to science curriculum and textbooks, language, religion, student learning in science, science teacher education and science education research and summarise the challenges and opportunities for research faced in each area. We conclude the paper by proposing a set of policy and research recommendations that could aid in the development of lasting solutions for recurring problems.  相似文献

ABSTRACT

While the literature is replete with studies examining teacher knowledge and pedagogical content knowledge (PCK), few studies have investigated how science teacher orientations (STOs) shape classroom instruction. Therefore, this research explores the interplay between a STOs and the topic specificity of PCK across two science topics within a grade 9 earth science course. Through interviews and observations of one teacher’s classroom across two sequentially taught, this research contests the notion that teachers hold a single way of conceptualising science teaching and learning. In this, we consider if multiple ontologies can provide potential explanatory power for characterising instructional enactments. In earlier work with the teacher in this study, using generic interview prompts and general discussions about science teaching and learning, we accepted the existence of a unitary STO and its promise of consistent reformed instruction in the classroom. However, upon close examination of instruction focused on different science topics, evidence was found to demonstrate the explanatory power of multiple ontologies for shaping characteristically different epistemological constructions across science topics. This research points to the need for care in generalising about teacher practice, as it reveals that a teacher’s practice, and orientation, can vary, dependent on the context and science topics taught.  相似文献
