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

Laboratory instruction is critical to the understanding of biology and is a central piece of biological sciences instruction. Although much investigation has focused on the content of biology laboratory exercises, we contend that understanding the extent to which the laboratory materials can aid or limit experimental investigation is of equal importance. In this study, therefore, we investigate the role of timing and availability of laboratory equipment in the context of two different laboratory exercises. We use both case study and an experimental approach to investigate how laboratory materials guide the planning, context, creativity, and timing of ideas shared among students. Our data support the notion that providing students with laboratory equipment before students plan and consider different experimental approaches can constrain students' ideas and encourage tool‐focused solutions to experimental design tasks. © 2011 Wiley Periodicals, Inc.

Objectives
This study examined individual and contextual factors that explain students’ victimization by peers among 4th- through 6th-grade Jewish and Arab students.Method
A total of 120 homeroom teachers and 3,375 students from 47 schools participated. The study explored how students’ reports of violence are influenced by individual factors (gender, age, perception of school climate, victimization by teachers, and fear) teacher-class factors (school climate, homeroom teachers’ characteristics such as self-efficacy, and education) and cultural affiliation as a school level factor.Results
The results showed that levels of victimization vary significantly between classes and between schools. However, the vast majority of variation in students’ victimization lay at the individual level. Factors such as fear, physical and emotional victimization by teachers, and gender affected levels of students’ victimization by peers.Conclusions
Students victimized by peers are more likely to be victimized by their teachers and to miss school because of their fear of violence. Further research should be conducted to investigate additional teacher, class and school factors that can predict levels of students’ victimization.Practice implication
Based on the study's results, efforts to deal with school violence should be targeted to students and school staff. It is essential to design and implement a “whole school” approach that includes participation of the entire school community. Furthermore, intensive individual treatment should be given to victimized students to improve their sense of safety and protection on school property. In addition, the findings emphasized the need to design and implement school intervention programs in a sensitive way that takes into consideration children's developmental stages and other factors that affect their levels of victimization. The results showed that younger children do not take advantage of the many positive effects that can be achieved from positive school policy and good relationships with staff. It might be that more efforts should be made to raise victimized students’ awareness by emphasizing that schools have rules that are there to protect them. 相似文献994.

Social stories have been widely used for children with autism and developmental delays; however, little research has been conducted that examines their effectiveness with pre‐school children who have no developmental delays. The present study investigated this previously undocumented use of social stories. Social stories were used to decrease aggression and improve positive peer relations in a Head Start pre‐school setting. Participants included three four‐year‐old pre‐school students. A single‐subject, ABC multiple baseline design with counterbalanced treatment order was implemented where social stories were compared to a neutral book. Direct observations and pre‐ and post‐Behaviour Assessment System for Children‐2 (BASC‐2) Teacher Rating Scale (TRS) scores were examined. Results revealed some support for the usefulness of social stories in this setting and with this population. Limitations of the study are discussed and directions for future research are provided. 相似文献

Lecturing style teaching and student performance 总被引:1,自引:0,他引:1

Teachers in the Netherlands tend to spend less time in front of the class, and often adopt a more personal approach. This allows them to better adjust their lecturing style to the needs of the individual student with the aim of increasing student performance. However, a more personal approach is also more time consuming and potentially reduces the complementary and scale effects of the more traditional lecture style teaching.This study examines whether the proportion of time that teachers lecture in front of the class influences the cognitive performance of students in the Netherlands. In this study we find no relationship between the proportion of time spent lecturing in front of the class and student performance. 相似文献

This study examines two experienced teachers’ transformations and sense of agency as they implemented a writer’s workshop curriculum with multi-lingual third grade students. Multiple lines of inquiry guide the study including communities of practice (Lave & Wenger, 1991), teacher identities in figured worlds (Holland, Lachicotte, Skinner, & Cain, 1998), and the ethic of care (Noddings, 1984/2003). A constant comparative method was used to analyze classroom observation notes, interviews and debriefing sessions (Glaser & Strauss, 1967). Findings indicate that teachers transformed their pedagogical practices around writing, and at the same time reconsidered what it may mean to become renewed professionals. 相似文献

This three-year study combines qualitative and quantitative analyses of effects of a one-week, intensive urban field placement on 95 suburban and rural teacher candidates’ self-reported perceptions of urban schools, students, teachers. Data was drawn from anonymous, open-ended, pre- and post-experience participant surveys; reflections; and alumni interviews. Findings include improvement in confidence in cross-cultural teaching abilities and interest in urban schools for future employment. Pre-service teachers’ perceptions can be meaningfully influenced by a short-term, cross-cultural immersion program when it is situated within a mutually-reinforcing, multicultural education curriculum that offers significant faculty scaffolding and structured reflection. 相似文献

This article explores whether features associated with effective professional communities among K-12 teachers are relevant and sufficient for improving the practice of supervisors in teacher education programs. Interview and observational data from nineteen supervisors in one teacher education program illuminate what supervisors want in order to improve their professional practices and how their needs could be met through ongoing collaboration. The article proposes five features of professional communities that can help supervisors improve their work: norms promoting collaboration; trust and familiarity; activities deprivatizing practices; access to logistical information and shared expectations about the role of supervisors; and time for collaboration. 相似文献

This article uses four academics’ gendered and cultural responses to life in a university in Aotearoa New Zealand under the new managerialist regime. Performance Based Research Funding (PBRF) requires academics to submit evidence‐based portfolios every six years to categorise and rank them, with government funding assigned accordingly. When the authors met as members of a writing group, the talk often turned to negative aspects of PBRF. Using co‐operative enquiry, the four co‐researchers began writing observations of their individual experiences, differences and identities to help them reflect and understand the impact of the changed environment. The four phases of writing as enquiry were: deciding on a focus, writing observations, engaging with the written accounts and interpreting the outcome through metaphor. The article process facilitated a positive outcome by helping the authors regain a sense of collegiality and mutual support, along with a sense of preserving their academic identity by writing and publishing as a group. 相似文献

This paper explores aspects of professional development for teachers of science and mathematics in schools in rural Australia. The study identified a range of issues including tensions between government, school and individual professional learning priorities and their respective responsibilities; the shaping of professional development by rurality; and issues of generic versus subject-specific professional learning. The paper will focus on the needs of teachers, particularly secondary teachers, for subject-specific professional development and the capacity of different professional development approaches for satisfying these needs. The notion of discourse communities is proposed as a framework for considering this issue. 相似文献
