Reform‐based curriculum materials have been suggested as a mechanism to make inquiry‐based instruction more prevalent in secondary science classrooms, specifically when accompanied by comprehensive professional development (Loucks‐Horsley, Hewson, Love, & Stiles, 1998 ; Powell & Anderson, 2002 ). This research examines the implementation of a reform‐based high school chemistry curriculum in a large, urban school district. We explicitly consider the role of the teachers' knowledge and beliefs in their implementation of the reform‐based chemistry curriculum, as well as school level factors. Qualitative and quantitative data were collected in the form of beliefs interviews and classroom observations from 27 high school chemistry teachers. Analysis of the data revealed that implementation of the curriculum was strongly influenced by the teachers' beliefs about teaching and learning, and the presence of a supportive network at their school sites. © 2007 Wiley Periodicals, Inc.

A representative sample of undergraduate and postgraduate international students at a large Australian university (n=979, 64% females) completed a mail-back survey of their health and wellbeing. Most students evaluated their current and previous physical and mental health positively. Health-related risk practices such as unprotected sexual activity, drug use, smoking and gambling, were reported by few students. There was little change in health or risk behaviours since coming to Australia and few changes that were health compromising. Few demographic or situational variables, including age and gender, had a significant impact on students' wellbeing. This study has revealed that few international students find the experience of studying in an overseas country detrimental to their wellbeing. Nevertheless, for those students who encounter difficulties or are at increased risk of health-compromising outcomes, we must ensure better delivery of health promotion education, and access to, and use of, available counselling and health services.

The authors examined second grade reading accuracy and fluency and their associations via letter knowledge to phonological and language predictors assessed at 3.5, 4.5, and 5.5 years in children in the Jyv?skyl? Longitudinal Study of Dyslexia. Structural equation modeling showed that a developmentally highly stable factor (early phonological and language processing [EPLP]) behind key dyslexia predictors (i.e., phonological awareness, short-term memory, rapid naming, vocabulary, and pseudoword repetition) could already be identified at 3.5 years. EPLP was significantly associated with reading and spelling accuracy and by age with letter knowledge. However, EPLP had only a minor link with reading fluency, which was additionally explained by early letter knowledge. The results show that reading accuracy is well predicted by early phonological and language skills. Variation in fluent reading skills is not well explained by early skills, suggesting factors other than phonological core skills. Future research is suggested to explore the factors behind the development of fast and accurate decoding skills.  相似文献

Research illustrates the positive roles of perceived competence, autonomy, and mastery climate and the negative role of performance climate in student motivation in physical education. Less research has examined perceptions of relationships within this setting (i.e., perceived teacher support and relatedness) and their role in student motivation. The purpose of this study was to test the mediating roles of perceived competence, autonomy, and relatedness in the relationship between social contextual factors and motivation in physical education students (N = 508). Results from structural equation modeling showed that perceived competence, autonomy, and relatedness partially mediated the relationship between perceived teacher support and self-determined motivation and that mastery climate related directly to self-determined motivation. The results highlight the importance of perceived teacher support, mastery climate, and relatedness to motivation in physical education.  相似文献

Research Findings. The present study examined relations between social-cognitive skills, aggression, and social competence using teacher questionnaires and tabletop tasks with preschool and kindergarten children. It was hypothesized that the acquisition of a theory of “mind”, as indexed by an understanding of false beliefs, might be related to social behavior for this age group. Overall, results indicated that both generation of forceful solutions in a traditional social-problem solving task and performance on the false belief tasks were significantly related to social competence, after controlling for the effects of age, language comprehension, and teacher ratings of aggression. In addition, theory of mind understanding was a better predictor of social competence than performance on a more traditional social information-processing task that involved the generation of alternative solutions to interpersonal problems. Practice. The implications of these findings for preschool and kindergarten peer relations and their potential relevance to treatment of deficits in social skills are discussed. Specifically, training in an understanding of counterfactual thinking (e.g., through increased and structured opportunities to engage in pretend play and storytelling) may enhance preschooler social skills.  相似文献

This study investigated the psychometric characteristics of constructed-response (CR) items referring to choice and non-choice passages administered to students in Grades 3, 5, and 8. The items were scaled using item response theory (IRT) methodology. The results indicated no consistent differences in the difficulty and discrimination of the items referring to the two types of passages. On the average, students' scale scores on the choice and non-choice passages were comparable. Finally, the choice passages differed in terms of overall popularity and in their attractiveness to different gender and ethnic groups  相似文献

A sample of college-bound juniors from 275 high schools took a test consisting of 70 math questions from the SAT. A random half of the sample was allowed to use calculators on the test. Both genders and three ethnic groups (White, African American, and Asian American) benefitted about equally from being allowed to use calculators; Latinos benefitted slightly more than the other groups. Students who routinely used calculators on classroom mathematics tests were relatively advantaged on the calculator test. Test speededness was about the same whether or not students used calculators. Calculator effects on individual items ranged from positive through neutral to negative and could either increase or decrease the validity of an item as a measure of mathematical reasoning skills. Calculator effects could be either present or absent in both difficult and easy items  相似文献

This study investigated the psychometric properties of the Elementary Social Behaviour Assessment (ESBA), a teacher-report measure of students’ social skills and academic engagement adapted for use in Norwegian schools. At two times, 8 weeks apart, 151 teachers rated 793 students in Grades 1–6 on the ESBA and the Social Skills Rating System Teacher’s form (SSRS-T). Exploratory factor analysis with the first assessment suggested one or possibly two factors. Confirmatory factor analysis with the second assessment confirmed the one- or two-factor models but did not offer strong evidence for one over the other. The ESBA demonstrated good to excellent reliability. Strong concurrent and predictive correlations with the SSRS-T established criterion validity. The school and teacher levels explained only a limited amount of the total variance in ESBA scores, suggesting that teachers rate students quite similarly. The Norwegian-adapted ESBA paralleled the reliability and validity evidence from US samples.  相似文献
