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

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

This study (a) assessed the influence of an integrated nature of science (NOS) instructional intervention on inservice secondary science teachers' understandings, retention of those understandings, and their NOS instructional planning and practices; and (b) examined factors that mediated the translation of teachers' NOS understandings into practice. Nineteen teachers participated in an intensive, 6-week NOS course, which concluded with teachers developing plans to address NOS in their classrooms. Next, 6 participants were observed as they implemented their instructional plans. Data sources included pretest, posttest, and delayed-test NOS assessments, classroom observations, and several teacher-generated artifacts. The NOS course was effective in helping teachers develop informed NOS conceptions and retain those understandings 5 months after its conclusion. Teachers met with challenges and successes as they attempted to address NOS instructionally. The translation of NOS conceptions into practice was primarily mediated by the very nature of teachers' newly acquired NOS understandings, which were situated within the science contents, contexts, and experiences in which they were developed (i.e. the NOS course); thus, limiting participants' abilities to transfer their understandings into novel contexts and contents. The results helped build a model of the sources of science teachers' pedagogical content knowledge for teaching about NOS in content-rich contexts.  相似文献

Attaining the vision for science teaching and learning emphasized in the Framework for K‐12 Science Education and the next generation science standards (NGSS) will require major shifts in teaching practices in many science classrooms. As NGSS‐inspired cognitively demanding tasks begin to appear in more and more science classrooms, facilitating students' engagement in high‐level thinking as they work on these tasks will become an increasingly important instructional challenge to address. This study reports findings from a video‐based professional development effort (i.e., professional development [PD] that use video‐clips of instruction as the main artifact of practice to support teacher learning) to support teachers' learning to select cognitively demanding tasks and to support students' learning during the enactment of these tasks in ways that are aligned with the NGSS vision. Particularly, we focused on the NGSS's charge to get students to make sense of and deeply think about scientific ideas as students try to explain phenomena. Analyses of teachers' pre‐ and post‐PD instruction indicate that PD‐participants began to adopt instructional practices associated with facilitating these kinds of student thinking in their own classrooms. The study has implications for the design of video‐based professional development for science teachers who are learning to facilitate the NGSS vision in science classrooms.  相似文献

Science education research, reform documents and standards include scientific argumentation as a key learning goal for students. The role of the teacher is essential for implementing argumentation in part because their beliefs about argumentation can impact whether and how this science practice is integrated into their classroom. In this study, we surveyed 42 middle school science teachers and conducted follow-up interviews with 25 to investigate the factors that teachers believe impact their argumentation instruction. Teachers responded that their own learning goals had the greatest impact on their argumentation instruction while influences related to context, policy and assessment had the least impact. The minor influence of policy and assessment was in part because teachers saw a lack of alignment between these areas and the goals of argumentation. In addition, although teachers indicated that argumentation was an important learning goal, regardless of students' backgrounds and abilities, the teachers discussed argumentation in different ways. Consequently, it may be more important to help teachers understand what counts as argumentation, rather than provide a rationale for including argumentation in instruction. Finally, the act of trying out argumentation in their own classrooms, supported through resources such as curriculum, can increase teachers' confidence in teaching argumentation.  相似文献

In the study described in this article a questionnaire was employed that can be used to assess students' and teachers' perceptions of science teachers' interpersonal communication behaviors in their classroom learning environments. The Teacher Communication Behavior Questionnaire (TCBQ) has five scales: Challenging, Encouragement and Praise, Non‐Verbal Support, Understanding and Friendly, and Controlling. The TCBQ was used with a large sample of secondary science students in Taiwan, which provided additional validation data for the TCBQ for use in Taiwan and cross‐validation data for its use in English‐speaking countries. Girls perceived their teachers as more understanding and friendly than did boys, and teachers in biological science classrooms exhibited more favorable behavior toward their students than did those in physical science classrooms. Differences were also noted between the perceptions of the students and their teachers. Positive relationships were found between students' perceptions of their teachers' communication behaviors and their attitudes toward science. Students' cognitive achievement scores were higher when students perceived their teacher as using more challenging questions, as giving more nonverbal support, and as being more understanding and friendly. The development of both teacher and student versions of the TCBQ enhances the possibility of the use of the instrument by teachers. © 2002 John Wiley & Sons, Inc.

The aim of the study was to discover the essential characteristics of engineering teachers' pedagogical content knowledge by studying teachers' conceptions of their students' ideas of moment. To compare the conceptions maintained by teachers with those of their students, the most common difficulties experienced by first-year engineering students in understanding the moments of forces were looked at. The data on students' conceptions were collected by means of a questionnaire. In addition, four experienced teachers were given the same questionnaire as the students and then were asked to write what they expected the students' answers to be. The students' answers and the teachers' conceptions of their students' potential answers were compared. It was found that although the teachers originally appeared to be familiar with their students' conceptions, they were rather astonished by the general pattern of the students' thinking. It is planned that the information gathered about the teachers' pedagogical content knowledge will eventually be used to improve engineering teacher training.  相似文献

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.

The goal of the present study was to investigate the link between elementary school teacher burnout and students' perceptions of teacher social–emotional competence (SEC). A total of 676 Grades 4–7 students in 35 classrooms rated their classroom teachers' SEC. In addition, teachers self-reported their current level of experienced burnout at work (i.e., depersonalization and emotional exhaustion). Multilevel analyses revealed significant classroom-level variability (i.e., 34%) in student-ratings of teacher SEC. Teacher burnout significantly predicted student-rated teacher SEC, over and above significant student-level variables (school self-concept, sense of autonomy in the classroom) and contextual variables (teacher age, school neighborhood income). Specifically, higher levels of teacher burnout were related to receiving lower SEC ratings by students. Teacher burnout explained a significant portion of the classroom-level variability in student-rated teacher SEC. The present study emphasizes the link between teacher burnout and the SEC. Furthermore, given that teacher reports (burnout) were linked to student reports (teacher SEC), these findings also suggest that students notice stress in their classroom teacher.  相似文献

In this article, the authors investigated the teacher practices that middle school students attend to when appraising their classroom's mastery goal structure. After students rated each item on the mastery goal structure scale, they wrote what their teacher did or said that led them to make that choice. Students' responses to the open-ended questions were coded thematically. The categories mentioned most often involved the pedagogical and affective nature of teachers' interactions with students. Recognition and evaluation practices and teachers' use of time were also salient to students. There were no differences in the practices that students attended to in classrooms with high, compared with low, mastery goal structure.  相似文献

Learning to teach science as inquiry in the rough and tumble of practice   总被引:2,自引:0,他引:2  
This study examined the knowledge, beliefs and efforts of five prospective teachers to enact teaching science as inquiry, over the course of a one‐year high school fieldwork experience. Data sources included interviews, field notes, and artifacts, as these prospective teachers engaged in learning how to teach science. Research questions included 1) What were these prospective teachers' beliefs of teaching science? 2) To what extent did these prospective teachers articulate understandings of teaching science as inquiry? 3) In what ways, if any, did these prospective teachers endeavor to teach science as inquiry in their classrooms? 4) In what ways did the mentor teachers' views of teaching science appear to support or constrain these prospective teachers' intentions and abilities to teach science as inquiry? Despite support from a professional development school setting, the Interns' teaching strategies represented an entire spectrum of practice—from traditional, lecture‐driven lessons, to innovative, open, full‐inquiry projects. Evidence suggests one of the critical factors influencing a prospective teacher's intentions and abilities to teach science as inquiry, is the teacher's complex set of personal beliefs about teaching and of science. This paper explores the methodological issues in examining teachers' beliefs and knowledge in actual classroom practice. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 44: 613–642, 2007.  相似文献

The efficacy of placing students with special needs in inclusive classrooms may depend in part on how instructional factors contribute to student outcomes. Differences in frequencies and levels of cognitive engagement of interactions among nine teachers in inclusive elementary classrooms were related to three other variables: teachers' ratings on the Pathognomonic-Interventionist (PATH/INT) Scale, students' designation either as exceptional or at-risk (EX/AR) or as typically achieving (TA), and students' scores on the Piers Harris Children's Self-Concept Scale. Teachers with PATH beliefs, who attribute learning difficulties to permanent characteristics of the student that are beyond the teacher's mandate, interacted infrequently with their EX/AR students at low levels of cognitive engagement. Teachers with INT beliefs, who see themselves as responsible for the achievement of all their students irrespective of their disabilities, interacted with all students more frequently, and at higher levels of cognitive engagement. In contrast to the PATH teachers, their EX/AR students received more instructional interactions than their TA students. As expected, the EX/AR students in all classrooms had lower Piers Harris Self-Concept Total Scale scores than typically achieving students. However, both TA and EX/AR students had lower Self-Concept Total Scale scores in the classrooms of teachers with PATH beliefs, compared to students in the classrooms of INT teachers. The relationship is discussed between teachers' beliefs, their different patterns of instructional interactions with students with and without disabilities in inclusive classrooms, and the possible impact of instructional interventions on students' self-concept.  相似文献

This paper examines the context of teacher education in which certain students work as teachers whilst at the same time they study in a teacher education programme. The two phenomena that are discussed are the integration of theory and practice, and learning while working. These are located in the wider framework of teachers' pedagogical thinking, and research‐based teacher education. The paper reports on students' experiences of the success of integrating theoretical studies in their work as teachers and the related issue of how a student's everyday grasp of classroom practice has been taken into account in their studies. The paper also raises the issue of the university–school relationship through students' estimations of the impact that their participation in teacher education has brought to the school in which they work and other key aspects of the university–school relationship.  相似文献

Existing research indicates inconsistent or at best weak predictive effects of teacher knowledge on student achievement. Data from Germany were used to examine the relation between teachers' content and pedagogical content knowledge, their perception, interpretation, and decision-making skills, the instructional quality implemented in class, and students' learning progression in mathematics. Rather than direct effects of teacher knowledge on students, we hypothesized an effect chain with multiple mediation processes while controlling for school type and student background. Multi-level modeling with 3496 students from 154 classrooms revealed a mediating role of teachers' skills and their instructional quality for the relation between teacher knowledge and students' learning progress. Effect sizes were medium to strong, and the model explained a large amount of variance. No direct effects of teachers’ knowledge on student progress were found. We discuss our findings with respect to the teacher-competence-as-a-continuum model and with respect to future research.  相似文献

Fostering students' spatial thinking skills holds great promise for improving Science, Technology, Engineering, and Mathematics (STEM) education. Recent efforts have focused on the development of classroom interventions to build students' spatial skills, yet these interventions will be implemented by teachers, and their beliefs and perceptions about spatial thinking influence the effectiveness of such interventions. However, our understanding of elementary school teachers' beliefs and perceptions around spatial thinking and STEM is in its infancy. Thus, we created novel measures to survey elementary teachers' anxiety in solving spatial problems, beliefs in the importance of spatial thinking skills for students' academic success, and self-efficacy in cultivating students' spatial skills during science instruction. All measures exhibited high internal consistency and showed that elementary teachers experience low anxiety when solving spatial problems and feel strongly that their skills can improve with practice. Teachers were able to identify educational problems that rely on spatial problem-solving and believed that spatial skills are more important for older compared to younger students. Despite reporting high efficacy in their general teaching and science teaching, teachers reported significantly lower efficacy in their capacities to cultivate students' spatial skills during science instruction. Results were fairly consistent across teacher characteristics (e.g., years of experience and teaching role as generalist or specialist) with the exception that only years of teaching science was related to teachers' efficacy in cultivating students' spatial thinking skills during science instruction. Results are discussed within the broader context of teacher beliefs, self-efficacy, and implications for professional development research.  相似文献

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

This study examined the effects of classroom assessment practices on students' achievement goals. The study included 1,636 ninth grade students and 83 science teachers from Muscat public schools in Oman. Results from hierarchical linear modeling techniques showed that class contextual features and teachers' teaching experiences and assessment practices interacted significantly with students' characteristics in influencing students' achievement goals. Recommendations, implications, and suggestions for practice and future research are discussed.  相似文献

What are the barriers to technology‐rich inquiry pedagogy in urban science classrooms, and what kinds of programs and support structures allow these barriers to be overcome? Research on the pedagogical practices within urban classrooms suggests that as a result of many constraints, many urban teachers' practices emphasize directive, controlling teaching, that is, the “pedagogy of poverty” (Haberman, 1991 ), rather than the facilitation of students' ownership and control over their learning, as advocated in inquiry science. On balance, research programs that advocate standards‐based or inquiry teaching pedagogies demonstrate strong learning outcomes by urban students. This study tracked classroom research on a technology‐rich inquiry weather program with six urban science teachers. The teachers implemented this program in coordination with a district‐wide middle school science reform. Results indicated that despite many challenges in the first year of implementation, students in all 19 classrooms of this program demonstrated significant content and inquiry gains. In addition, case study data comprised of twice‐weekly classroom observations and interviews with the six teachers suggest support structures that were both conducive and challenging to inquiry pedagogy. Our work has extended previous studies on urban science pedagogy and practices as it has begun to articulate what role the technological component plays either in contributing to the challenges we experienced or in helping urban science classrooms to realize inquiry science and other positive learning values. Although these data outline results after only the first year of systemic reform, we suggest that they begin to build evidence for the role of technology‐rich inquiry programs in combating the pedagogy of poverty in urban science classrooms. © 2002 John Wiley & Sons, Inc.

An examination was made concerning the relationships between Sudanese secondary science teachers' pupil control ideology and their students' perceptions/observations of the psychosocial environment of their science classrooms. One hundred secondary science teachers were classified as possessing humanistic (N = 20) or custodial (N = 20) control ideologies. A class (N = 40) of students was randomly selected for every teacher in both groups. The findings revealed that no significant relationships existed between the control ideologies of the teachers and their students' perceptions/observations of the classroom environment. Custodialism in control ideology was significantly related to the classroom environment psychosocial aspect of low “support.” Discussion and implications of the findings have been approached from both Sudanese and American perspectives.  相似文献
