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.

Reform efforts have emphasized the need to support teachers' learning about reform‐oriented practices. Educative curriculum materials are one potential vehicle for promoting teacher learning about these practices. Educative curriculum materials include supports that are intended to promote both student and teacher learning. However, little is known about the extent to which existing curriculum materials provide support for teachers and the ways they can be improved. In this study, eight sets of high school biology curriculum materials were reviewed to determine their potential for promoting teacher learning. Design heuristics for educative curriculum materials were adapted for use as evaluation criteria. From this analysis, several themes emerged. First, the materials tended to provide support for teachers' subject matter knowledge and pedagogical content knowledge for students' ideas (e.g., misconceptions) but rarely for their pedagogical content knowledge of scientific inquiry. Second, the materials contained several implementation guidance supports but far fewer rationales for instructional decisions, which are an important feature of educative curriculum materials. Finally, the quality of support varied widely, differing in its degree of relevance, pedagogical helpfulness, and depth. The article concludes with recommendations for the redesign of existing curriculum materials. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 46: 977–998, 2009 相似文献

This study examines: 1) how Korean elementary school teachers perceive recent curriculum reforms; 2) where their perceptions emanate from; and 3) what support teachers need in order to implement curriculum reforms actively and effectively. This study has shown that teachers generally harbour negative and unconstructive feelings about curriculum reform. These feelings negatively impact their involvement in and commitment to implementing reform. Several issues to be considered for teacher training and support evolved from our analysis of teachers' perceptions of the curriculum reform and the implementation: first, teachers are insufficiently provided with professional development programmes that support curriculum implementation; second, teachers lack opportunities to work through implementation problems and difficulties with peer teachers; and last, contextual and cultural constraints inhibit implementation of curriculum reform. Based upon these findings, this study makes several suggestions for teacher educators and curriculum policymakers. 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

The number of state-funded prekindergarten programs continues to grow in the United States. The quality of these early childhood programs, however, often depends on the type of professional development provided. In this investigative study, an experimental pre-post causal-comparative research design was employed to evaluate the impact of an 8-week curriculum course on state-funded prekindergarten teachers' knowledge about developmentally appropriate curriculum, their beliefs about best practice, and their actual observed classroom instructional performance. The 8-week course focused on equipping teachers of 4-year-olds with the content knowledge and instructional strategies necessary to promote children's learning. Based on research about the critical role of interactions on learning, the nature and types of exchanges between teachers and children became the focus of the professional-development initiative. Nine teachers attended the course and were evaluated before and after the training. A control group of 8 teachers was also assessed during the same time frame. An analysis of the data revealed that the course was effective in changing prekindergarten teachers' knowledge and practice. Results from pre-post measures of beliefs demonstrate that the outcomes were less significant. The impact of this focused professional-development initiative was not mediated by the participating teachers' level of education. 相似文献

Early Childhood Teachers' Curriculum Beliefs: Are They Consistent With Observed Classroom Practices?
Research Findings: This study examined the consistency between early childhood teachers' self-reported curriculum beliefs and observations of their actual interactive behaviors with children in classrooms. Also tested was the hypothesized moderation by teacher and classroom characteristics of the association between beliefs and practices. A total of 58 preschool teachers completed a survey describing their professional backgrounds and curriculum beliefs. Their classroom practices were observed using a newly developed instrument that documented teacher interactions with children. Most teachers in this sample strongly endorsed child-initiated learning beliefs, although their beliefs about teacher-directed learning varied considerably. The most frequently observed teacher behaviors in the classroom were giving directions to children, responding to children's initiations, and engaging in non-interactive classroom management activities. Overall, teachers' curriculum beliefs and observed classroom practices were weakly correlated. However, there were moderation effects. Stronger congruence between teacher-directed learning beliefs and observed teaching behaviors was found among teachers who had more professional training and more years of teaching experience. Practice or Policy: These results support the importance of early childhood teacher professional development. They suggest that teacher preparation and professional development programs should focus on the intellectual transformation between teacher knowledge and teacher practice, promoting both aspects of development. 相似文献

The last two decades have witnessed the gradual implementation of integrated science curriculum at the junior secondary level in China. However, in most provinces of China, the implementation is not as successful as expected. Challenges were reported, yet without fine-grained investigation, with respect to science teachers' instruction on integrated science. In this study, we aim to detect major problems by investigating the instruction of integrated science at the secondary level. Classroom observation focused on the teacher and student verbal behavior, teachers' competency of instructional organization, their presentation of instructional content, and the organization of learning activities. Findings revealed that students were provided with limited opportunities for participating and engaging in learning as science teachers were dominant in classroom talk. Teachers emphasized on the integration of knowledge within one subject (within-subject knowledge), but not the integration of knowledge between subjects (cross-subject knowledge), resulting in the unsuccessful instruction of the integrative content. What is more, teachers were inadequately competent in designing and delivering science, technology and society content, scientific inquiry and scientific experiments, which also affected the quality of instruction on integrated science. 相似文献

Professional development is seen as one of the major levers for aligning science instruction in the USA with the vision put forth by national standards documents. Although there is a growing consensus regarding what constitutes effective professional development, there is little empirical evidence to support this consensus. This study examines the impact of professional development that is content‐based, situated in classroom practice, and sustained over time on teacher attitudes, perceptions of preparedness, and classroom practices. It utilizes longitudinal data from the National Science Foundation's Local Systemic Change through Teacher Enhancement Initiative (LSC), collected from 42 projects over a span of 7 years. The professional development model used in the LSCs differed from previous initiatives in that it targeted all teachers in a jurisdiction and emphasized preparing teachers to implement project‐designated instructional materials. Analyses of the data provide evidence that this model for professional development has an impact on teachers and their classroom practices. In addition, the analyses found that teachers' perception of principal support for Standards‐based science instruction is an important predictor of these outcomes. © 2006 Wiley Periodicals, Inc.

This study examined the effect of fidelity of implementation (FOI) on the science achievement gains of third grade students broadly and students with limited literacy in English specifically. The study was conducted in the context of a professional development intervention with elementary school teachers to promote science achievement of ELL students in urban schools. As the criterion for measuring FOI, we focused on the quality of instructional delivery in teaching science to ELL students. We measured FOI using both teachers' self‐reports and classroom observations during the first year of the intervention. Science achievement was measured by a pretest and posttest over the school year. The results indicate that none of the measures of FOI using teachers' self‐reports or classroom observations had significant effects on science achievement gains. The results are discussed in terms of issues about conceptualization and measurement of FOI in educational interventions. © 2009 Wiley Periodicals, Inc. J Res Sci Teach 46: 836–859, 2009 相似文献

Situated in the context of the Advanced Placement curriculum reform in the sciences, this quantitative study validates selected elements of Desimone's (2009) conceptual framework on teacher professional development. Using national data sets with data from 133 336 students and 7434 teachers, multi-level structural equation models indicate that professional development participation and contextual school- and teacher-level factors influence teachers' classroom practices. In turn, aspects of instructional enactments characteristics are significantly, but very weakly, associated with student performance. Thus, this study reinforces calls to provide teachers opportunities for high-quality professional development and suggests to advance research that identifies effective instructional practices. 相似文献

A new special education strategy was launched in Finland by the Ministry of Education in 2007. The new Basic Act was enacted in 2010 and the new national core curriculum concerning three‐tiered support for pupils in 2011. Since the 1990s, teachers across Finland have participated in developing Finnish basic education towards greater inclusion. The goal of this study was to enhance understanding of the implementation of the Finnish educational reforms. In this study, teachers' perceptions of good inclusive teaching arrangements were analysed and compared with the theories of inclusive education. There is still a lack of information available on the implementation of inclusive education practices, and especially about teachers' experiences of teaching in inclusive classrooms. In 2010, basic education teachers (N = 327) in Lapland, Finland, were asked to describe their experiences and perceptions of inclusive teaching arrangements. The results indicated that teaching practices have become more diverse, flexible and differentiated, enabling teaching of diverse groups. More and more teachers preferred teaching in teams and planning their work together, showing that changes in schools change the teacher's profession too. In this study, a framework for inclusive schools was constructed through implementing the indexes of inclusion created by Booth and Ainscow. 相似文献

Elementary school teachers often implement classroom behavioral management systems to address student misbehavior. Common problems targeted by these systems are the inattentive, hyperactive, and impulsive behaviors characteristic of attention‐deficit/hyperactivity disorder (ADHD). This study examined teachers' attributions for why children display ADHD behaviors, and how such attributions affect their experiences with children in the context of interventions to manage these behaviors. Participants were 32 preservice teachers undertaking a practicum in a summer program for 137 children (Grades 1–3), some of whom had ADHD. Teachers were trained to implement classroom‐wide behavioral management. Teachers' attributions for children's ADHD behaviors were assessed using a vignette measure, before teachers had met their students or begun training on intervention techniques. When controlling for attributions regarding oppositional behavior, teachers' initial attributions for ADHD behaviors as less internal/controllable predicted children reporting more positive relationships with that teacher during the summer program. Teachers' initial attributions for ADHD behaviors as less stable predicted teachers' greater satisfaction with the intervention techniques during the summer program and their greater attunement to children's social networks. Cognitions about the causes of children's ADHD behaviors held by preservice teachers may relate to their subsequent experiences with children in the context of implementing classroom behavioral management. 相似文献

In the research reported in this article, we sought to understand the instructional practices of 26 secondary teachers from one district who use a problems-based mathematics textbook series (Core-Plus). Further, we wanted to examine beliefs that may be associated with their instructional practices. After analyzing data from classroom observations, our findings indicated that the teachers’ instructional practices fell along a wide continuum of lesson implementation. Analysis of interview data suggested that teachers’ beliefs with regard to students’ ability to do mathematics were associated with their level of lesson implementation. Teachers also differed, by level of instructional practices, in their beliefs about appropriateness of the textbook series for all students. Results strongly support the need for professional development for teachers implementing a problems-based, reform mathematics curriculum. Further, findings indicate that the professional development be designed to meet the diverse nature of teacher needs. 相似文献

This study investigated a professional development model designed to improve teachers' inquiry teaching efficacy as well as the quality of their inquiry instruction through engaging teachers in practice-teaching and reflection sessions. The programme began with a two-week summer Institute focused on both inquiry pedagogy and science content and continued with academic year support for participants' inquiry implementation. An inquiry teaching efficacy instrument was administered 3 times to 25 teacher participants to gauge changes in their personal self-efficacy and outcome expectancy across 5 essential features of classroom inquiry. To examine actual practices, pre/post classroom observations of the teachers' inquiry enactments were evaluated using a quality of inquiry observation protocol. Following the summer Institute, teachers had statistically significant increases in their self-efficacy for teaching inquiry in four of the five essential features and increases in one of the five essential features for outcome expectancy. Teachers' quality of inquiry teaching also increased after the professional development programme. We discuss implications of this PD model for moving teachers towards implementation of new instructional techniques as well as the influence of a supportive school community on teachers’ efficacy with inquiry instruction. 相似文献

Instructional practices in secondary science: How teachers achieve local and standards-based success
Beth A. Covitt Elizabeth Xeng de los Santos Qinyun Lin Christie Morrison Thomas Charles W. Anderson 《科学教学研究杂志》2024,61(1):170-202
This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful—respected by students, parents, colleagues, and administrators—but they differed in their success in supporting students' three-dimensional learning. Our goal is to understand how the teachers' instructional practices contributed to their similarities in achieving local success and to differences in enabling students' learning, and to consider the implications of these findings for research-practice partnerships. Data sources included classroom videos supplemented by interviews with teachers and focus students and examples of student work. We also compared students' learning gains by teacher using pre–post assessments that elicited three-dimensional performances. Analyses of classroom videos showed how all six teachers achieved local success—they led effectively managed classrooms, covered the curriculum by teaching almost all unit activities, and assessed students' work in fair and efficient ways. There were important differences, however, in how teachers engaged students in science practices. Teachers in classrooms where students achieved lower learning gains followed a pattern of practice we describe as activity-based teaching, in which students completed investigations and hands-on activities with few opportunities for sensemaking discussions or three-dimensional science performances. Teachers whose students achieved higher learning gains combined the social stability characteristic of local classroom success with more demanding instructional practices associated with scientific sensemaking and cognitive apprenticeship. We conclude with a discussion of implications for research-practice partnerships, highlighting how partnerships need to support all teachers in achieving both local and standards-based success. 相似文献

Recent instructional reforms in science education aim to change the way students engage in learning in the discipline, as they describe that students are to engage with disciplinary core ideas, crosscutting concepts, and the practices of science to make sense of phenomena (NRC, 2012). For such sensemaking to become a reality, there is a need to understand the ways in which students' thinking can be maintained throughout the trajectory of science lessons. Past research in this area tends to foreground either the curriculum or teachers' practices. We propose a more comprehensive view of science instruction, one that requires attention to teachers' practice, the instructional task, and students' engagement. In this study, by examining the implementation of the same lesson across three different classrooms, our analysis of classroom videos and artifacts of students' work revealed how the interaction of teachers' practices, students' intellectual engagement, and a cognitively demanding task together support rigorous instruction. Our analyses shed light on their interaction that shapes opportunities for students' thinking and sensemaking throughout the trajectory of a science lesson. The findings provide implications for ways to promote rigorous opportunities for students' learning in science classrooms. 相似文献

Attempts to improve the quality of education in Botswana have, inter alia, included an emphasis on a learner-centered pedagogy. Attempts at implementing this pedagogy have been made within the ambit of the technical rational model of curriculum development. The attempts, however, have produced inconclusive results, and these results have often been rationalized in technicist terms, e.g., as being due to lack of resources and poorly trained teachers. Overlooked in this technicist model are the teachers' perspectives on the innovation. Using the case-study approach within the rubrics of the qualitative research paradigm, this study sought to establish the perspectives of geography teachers in a senior secondary school in Botswana vis-a-vis the learnercentered pedagogy advocated in Education for Kagisano ( Social Harmony ), a report produced by the 1977 Commission on Education. The findings indicated that teachers' classroom practices were influenced by many factors other than technical ones: these included the teachers' assumptions about the nature of knowledge and the ways it ought to be transmitted, their perceptions of students, and the goal of schooling. It also emerged that their assumptions were incongruent with the basic tenets of the learner-centered pedagogy. The findings, then, are an indictment of the technical rational model of change implementation applied in Botswana. They indicate that disregarding what teachers know and think about their taken-for-granted classroom practices when effecting change can lead to disappointing results. 相似文献

Primary science education is a concern around the world and quality mentoring within schools can develop pre‐service teachers' practices. A five‐factor model for mentoring has been identified, namely, personal attributes, system requirements, pedagogical knowledge, modelling, and feedback. Final‐year pre‐service teachers (mentees, n = 211) from three Turkish universities were administered a previously validated instrument to gather perceptions of their mentoring in primary science teaching. ANOVA indicated that each of these five factors was statistically significant (p<.001) with mean scale scores ranging from 3.36 to 4.12. Although mentees perceived their mentors to provide evaluation feedback (95%), model classroom management (88%), guide their preparation (96%), and outline the science curriculum (92%), the majority of mentors were perceived not to assist their mentees in 10 of the 34 survey items. Professional development programmes that target the specific needs of these mentors may further enhance mentoring practices for advancing primary science teaching. 相似文献
