Flexibility in problem solving has been widely recognized as an important skill for students' mastery of mathematics. Here we utilize the Opportunity-Propensity framework to investigate student characteristics, teacher characteristics, and teacher instructional practices that may be associated with students' gains in flexibility in algebra. Teacher and student data were collected from 8th and 9th grade Algebra I teachers in Massachusetts as part of a larger study on the impact of a researcher-developed year-long supplementary curriculum that focused on improving students' flexibility. We explore student demographics, teacher background characteristics and teacher instructional practices as predictors of student gains in flexibility. We further investigate instructional practices associated with flexibility gains through an analysis of teacher questioning in the classroom for teachers whose students achieved the greatest gains in flexibility and those whose students achieved the least gains. Our results indicate that prior knowledge is a reliable predictor of flexibility gains and that gender is an important student background characteristic associated with the development of flexibility. In addition, although high and low gain teachers did not differ in their implementation fidelity, high flexibility gain teachers asked more open-ended questions that prompted students to verbalize the main ideas of the lesson. 相似文献

This study investigated how professional development featuring evidence‐based customization of technology‐enhanced curriculum projects can improve inquiry science teaching and student knowledge integration in earth science. Participants included three middle school sixth‐grade teachers and their classes of students (N = 787) for three consecutive years. Teachers used evidence from their student work to revise the curriculum projects and rethink their teaching strategies. Data were collected through teacher interviews, written reflections, classroom observations, curriculum artifacts, and student assessments. Results suggest that the detailed information about the learning activities of students provided by the assessments embedded in the online curriculum motivated curricular and pedagogical customizations that resulted in both teacher and student learning. Customizations initiated by teachers included revisions of embedded questions, additions of hands‐on investigations, and modifications of teaching strategies. Student performance improved across the three cohorts of students with each year of instructional customization. Coupling evidence from student work with revisions of curriculum and instruction has promise for strengthening professional development and improving science learning. © 2010 Wiley Periodicals, Inc.

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

In order to improve student achievement, school systems must provide new teachers with support to become effective teachers more quickly. Educators frequently use mentoring to support new teachers and reach the goals of improved classroom performance as well as teacher retention. The intention in this study was to provide insights into the mentoring of beginning teachers working in the middle grades. In this exploratory case study, three elements of a mentoring model deemed necessary for the implementation of effective mentoring for middle school teachers are presented. First, the mentor must forge a trusting relationship with the new teacher. Second, the mentor must support and guide the new teacher in creating a classroom environment that is supportive of learning. Third, the mentor must be able to support and guide the new teacher in instructional strategies appropriate to the content and context of the classroom. Furthermore, this research highlighted a need for mentors to receive ongoing training in classroom management, instructional practices, and relationship building in order to remain effective mentors. Without effective trained mentors programs will fail to meet their goals of improving instruction and retaining teachers past their induction year. 相似文献

Portfolios have gained wide acceptance as a learning and assessment tool. Yet, little research has been reported on the practices of teachers who are actually using portfolios within their classrooms and how those practices are moderated by contextual variables. This research examined the instructional, learning, and assessment roles of student portfolios and explored, from the perspective of the classroom teacher, variations in portfolio applications associated with teaching level (primary vs. intermediate) and classroom environment (self-contained vs. multiage-teaming). Kindergarten through Grade 5 teachers in 13 elementary schools completed a survey questionnaire regarding the instructional and assessment uses to which portfolios are put within their classrooms. To further examine for patterns of portfolio use, a subset of teachers was interviewed to explore the perceptions that teachers hold about the impact of student portfolios on themselves and on their students. The results suggest that Kindergarten through Grade 5 teachers make deliberate decisions regarding uses of their students' portfolios, decisions that appear heavily impacted by the maturity or skill level of the child, the purposes of the application, and the classroom environment within which the application occurs. They also depend on whether the portfolio product is in a formative state (working portfolio) or final state (performance portfolio). 相似文献

Teacher collaboration and support given from one teacher to another, focused on improving teaching and learning in the classroom, are notable by their absence in secondary schools in Bangladesh. This article identifies a number of constraints to developing a collaborative culture including the difficulty of the curriculum, the perceived low ability of many students, the teachers' own educational background and contextual factors which influence teachers' motivation. It suggests that informal collaboration for mutual support has the potential to increase teacher motivation but that this will only be achieved through building more collaborative ways of working through formal programmes grounded in classroom observation. It questions the validity for Bangladesh teachers of the model of teacher development programmes focused on teacher collaboration which emphasise teaching the ‘perfect’ lesson and suggests that without attention to student learning such programmes are unlikely to lead to increased collaboration or improved teacher practice in schools. 相似文献

Mastery of algebra is an important yet difficult milestone for students, suggesting the need for more effective teaching strategies in the algebra classroom. Learning by comparing worked-out examples of algebra problems may be one such strategy. Comparison is a powerful learning tool from cognitive science that has shown promising results in prior small-scale studies in mathematics classrooms. This study reports on a yearlong randomized controlled trial testing the effect of an Algebra I supplemental comparison curriculum on students’ mathematical knowledge. 141 Algebra I teachers were randomly assigned to either implement the comparison curriculum as a supplement to their regular curriculum or to be a ‘business as usual’ control. Use of the supplemental curriculum was much less frequent than requested for many teachers, and there was no main effect of condition on student achievement. However, greater use of the supplemental curriculum was associated with greater procedural student knowledge. These findings suggest a role for comparison in the algebra classroom but also the challenges of supporting teacher integration of new materials into the curriculum. 相似文献

This study explored the classroom learning environments and instructional strategies of four teachers in culturally diverse classrooms. All teachers were deemed successful by their school colleagues, including administrators and instructional specialists, at meeting the needs of their culturally diverse students. The teachers in the study, who were teaching in four different regions of the U.S.A. and who represented different grade levels, taught in schools that contained richly diverse student populations. Using the constant comparative method of data analysis, I conducted a cross-case analysis of the teachers' learning environments. A primary focus of the research was the relationship between teachers' biographies and culturally sensitive classroom instruction. Three themes about culturally sensitive teaching emerged during data analysis: reshaping traditional school curriculum, rethinking the role of the teacher, and acquiring and using cultural sensitivity. Implications for preparing teachers for culturally diverse learning environments are discussed. 相似文献

This study explores teachers’ first enactments of a set of theory-based curriculum materials designed to support academic language instruction. Specifically, this multiple case study looks at how six middle school English teachers in three US schools adapted the materials; each case includes a pair of teachers, one novice and one more experienced. All schools were located in the same district where a school performance measurement system was being used to publicly rank schools’ academic performance and growth. Multiple measures were used to look for evidence of adaptations and why teachers made adaptations. We found that all teachers adapted the curriculum, most often in response to either perceived student needs or district reform pressures. In two cases, patterns of adaptation differed by teacher experience; experienced teachers appeared better able to adapt curriculum materials to meet instructional goals. This pattern did not hold up at the third school, where teachers faced greater reform pressures. Taken together, these findings suggest that researchers should pay more attention to the role of school and district policy on teachers’ enactments of theory-based reforms. We conclude with guidance to researchers, instructional leaders and others interested in the potential of theory-based curricula as a lever for improving classroom instruction. 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 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

Abstract This paper addresses the nature of reflective classroom practice in a setting where action research has been undertaken by both the student teachers and the teaching practice supervisor. It is based on a cross‐case study of the processes through which student teachers learn to teach. Specifically, the analysis focuses on how student teachers reflect on their experiences in learning to teach. The data are based on student teachers’ reported thoughts about their learning over a period of one year. The results contribute to the understanding of reflective classroom practice by highlighting first student teachers’ perceptions about learning to teach and second their reviews on classroom practice. The discussion also adds to the literature on teacher development taken from the novice‐expert research tradition. Accordingly, implications for curriculum development in teacher education are drawn. 相似文献

This study investigated the extent to which teacher professional development led to changes in science instruction in K-2
classrooms in rural school districts. The research specifically examined changes in (a) teachers’ content knowledge in science;
(b) teachers’ self-efficacy related to teaching science; (c) classroom instructional time allotted to science; and (d) instructional
strategies used in science. The study also investigated contextual factors contributing to or hindering changes in science
instruction. Data sources included a teacher survey, a self-efficacy assessment, content knowledge tests, interviews, and
classroom observations. After one year in the program, teachers showed increased content knowledge and self-efficacy in teaching
science; they spent more instructional time on science and began using different instructional strategies. Key contextual
factors included curricular demands, resources, administrative support, and support from other teachers. 相似文献

The purpose of this study was to review and analyze effective classroom reading practices for early graders, using information gathered from the existing content-general and content-specific observation protocols measuring teachers’ classroom reading practices. Dimensions and constructs from 28 observation studies were synthesized to identify classroom instructional practices that have positive impacts on student achievement. Findings revealed that (a) instructional support, emotional support, and classroom management have positive impacts on student achievement, (b) the degree to which instructional practices are effective depends on students’ particular learning needs, and (c) students’ entering skills and primary language are associated with instructional effectiveness in reading. Challenges and implications for future research on effective instructional strategies for special education and the development of an observational protocol for special education teacher effectiveness are discussed. 相似文献

Patterns of verbal communications between a teacher and student can influence the classroom environment, quality of the instructional program, and student management in the classroom. This study examined teacher-student communication patterns in both regular and special education classes for behaviorally and emotionally handicapped students. It was expected that special class communication patterns would differ substantially from those used in regular classes. Those communications would result in more effective student management and more time on-task for learning. Webster's (1984, 1986) Process Interaction Model was used to analyze the communication patterns. Expected differences between how regular and special class teachers interact with students were not found. Implications of findings are discussed in relationship to teacher training, teacher effectiveness, and classroom management. 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

The use of computer conferencing environments with student teachers and their supervisors was implemented during teaching practice and evaluated for four teacher education programs. Computer conferencing can be contrasted with the more common supervision methods, such as face-to-face conferences between the student teacher and the cooperating teacher, or between a group of student teachers and their supervisor at the teacher education institute. In our evaluation, we focused on participants' opinions of computer conferencing and their participation, activities and educational outcomes. During their field experiences, student teachers used computer conferencing primarily to exchange emotional support when they recognised similar experiences among their peers. It was less used for reflecting on their teaching and exchanging pedagogical content knowledge, including instructional methods and designs, classroom management strategies, general and instructional theories, and aspects of the teaching profession. This finding led to the conclusion that more attention should be paid to the structure of student teachers' learning environment, because more coaching and instruction of student teachers in their systematic and reflective use of computer conferencing leads to more varied and extensive communication 相似文献

In this study we examined the relationship between teacher and student intrinsic motivation in project-based learning. The
participants were 126 Hong Kong secondary school teachers and their 631 students who completed evaluation questionnaires after
a semester-long project-based learning program. Both teachers and students were asked to indicate their motivation in the
program, and students were also asked to report the instructional support they received from their teachers. The results of
hierarchical linear modeling analyses showed that teacher intrinsic motivation predicted student intrinsic motivation directly
as well as indirectly through the mediation of instructional support. When teachers reported higher intrinsic motivation in
the program, their students tended to perceive receiving more support from them and to report higher intrinsic motivation
in the learning experience. 相似文献

The ability to analyze and understand classroom situations through the eyes of not only teachers but also students can be seen as a crucial aspect of teachers’ professional competence. Even though video case-based learning is considered to have great potential for the promotion of analytical competence of teachers (i.e., becoming immersed in student and teacher perspectives as well as applying conceptual knowledge to better understand classroom situations), only a few studies have investigated the effects of corresponding instructional support. This empirical field study examines the effects on analytical competence of two types of instructional support—hyperlinks to multiple perspectives and hyperlinks to conceptual knowledge—by using a 2 × 2 factorial design in a computer-supported video case-based learning environment inspired by cognitive flexibility theory and participatory design. The study examines collaborative learning processes to discover what specific kind of instruction may help to counteract some of the known deficits of case-based learning and teacher thinking, such as limited perspective-taking. From a participatory design point of view, training novices to become immersed in teacher and student perspectives can be considered as an alternative for direct involvement of teachers and students in the design process. The study was realized as a four-day university course for pre-service teachers (N = 100). ANCOVAs of learning processes (small-group discussions) and outcomes (written case analyses) provide evidence that both types of instructional support (i.e., hyperlinks to multiple perspectives and conceptual knowledge) are beneficial. In particular, hyperlinks to multiple perspectives affected small-group case discussions and written post-tests as they led to increased immersion (i.e., perspective-taking). Hyperlinks to conceptual knowledge furthered the application of this knowledge, especially in the written post-tests. Implications for teacher education, participatory design, and further research are discussed. 相似文献

Nearly every state evaluates teacher performance using multiple measures, but evidence has largely shown that only one such measure—teachers’ effects on student achievement (i.e., value-added)—captures teachers’ causal effects. We conducted a random assignment experiment in 66 fourth- and fifth-grade mathematics classrooms to evaluate the predictive validity of three measures of teacher performance: value-added, classroom observations, and student surveys. Combining our results with those from two previous random assignment experiments, we provide additional experimental evidence that value-added measures are unbiased predictors of teacher performance. Though results for the other two measures are less precise, we find that classroom observation scores are predictive of teachers’ performance after random assignment while student surveys are not. These results thus lend support to teacher evaluation systems that use value-added and classroom observations, but suggest practitioners should proceed with caution when considering student survey measures for teacher evaluation. 相似文献
