This study examined changes in student motivation and achievement in science during a visit to a university children’s science museum. The study was based on the pretest–posttest control comparison group design with four treatment groups: control, exhibit, lesson and exhibit/lesson. The sample consisted of 228 sixth-grade students from a Louisiana public school who were randomly assigned to one of the four experimental groups. Pretest, posttest and delayed posttest measures of intrinsic motivation and achievement in science were obtained using the Children’s Academic Intrinsic Motivation Inventory and an achievement test written to measure areas of science incorporated in the museum exhibits. The data were analysed using a one-way ANOVA, dependent t tests and Pearson r. Significant differences were found within groups for (1) the lesson group in motivation and (2) the exhibit group in achievement from pretest to posttest and from posttest to delayed posttest. A significant relationship between level of motivation and science achievement was revealed for the exhibit group on the delayed posttest. There were no other significant findings to support that the treatment led to any long-term effects on motivation or achievement within any of the four experimental groups.  相似文献

Designed-based research principles guided the study of 51 secondary-science teachers in the second year of a 3-year professional development project. The project entailed the creation of student-centered, inquiry-based, science, video games. A professional development model appropriate for infusing innovative technologies into standards-based curricula was employed to determine how science teacher’s attitudes and efficacy where impacted while designing science-based video games. The study’s mixed-method design ascertained teacher efficacy on five factors (General computer use, Science Learning, Inquiry Teaching and Learning, Synchronous chat/text, and Playing Video Games) related to technology and gaming using a web-based survey). Qualitative data in the form of online blog posts was gathered during the project to assist in the triangulation and assessment of teacher efficacy. Data analyses consisted of an Analysis of Variance and serial coding of teacher reflective responses. Results indicated participants who used computers daily have higher efficacy while using inquiry-based teaching methods and science teaching and learning. Additional emergent findings revealed possible motivating factors for efficacy. This professional development project was focused on inquiry as a pedagogical strategy, standard-based science learning as means to develop content knowledge, and creating video games as technological knowledge. The project was consistent with the Technological Pedagogical Content Knowledge (TPCK) framework where overlapping circles of the three components indicates development of an integrated understanding of the suggested relationships. Findings provide suggestions for development of standards-based science education software, its integration into the curriculum and, strategies for implementing technology into teaching practices.  相似文献

Changes in student self- and task evaluations, subjective valuation, and achievement behavior in mathematics and English over the 1st year of junior high form the basis of this study. The transition to junior high has been found to negatively affect students' self-concept and subjective valuation in mathematics and English, but previous research has not addressed changes in task evaluations and achievement behaviors. Gender and level of academic achievement effects are also relevant to the nature of changes in student attitudes. The participants (N =400) were from 3 coeducational Australian government schools in metropolitan Sydney of comparable socioeconomic status. When changes in perceptions occurred, they were negative, and gender differences favored boys in mathematics and girls in English. However, the nature and extent of change was dependent on school and level of achievement.  相似文献

This paper reports an investigation into Australian primary school teachers’ knowledge and confidence for mental health promotion. Questionnaires were delivered to 1397 teachers. In-depth interviews were held with 37 teachers. Quantitative results showed that half to two thirds of teachers felt efficacious and knowledgeable about selected components of mental health promotion. Independent judgments by staff about students’ mental health status concurred with students’ scores on the Strengths and Difficulties Questionnaire in about 75% of cases, indicating a good level of staff awareness about students’ mental health status. Exposure to the KidsMatter Primary mental health promotion initiative was associated with improvements in teachers’ efficacy, knowledge and pedagogy, with small to medium effect sizes. Qualitative analysis indicated that teachers’ subject-matter and pedagogical knowledge were heavily reliant on curriculum resources. Implications of the findings for the implementation of school-based mental health promotion initiatives are discussed.  相似文献

Abstract

The relationship between people and the rest of nature is central to the debate concerning the management of natural resources. An understanding of how environmental concern is reflected in people's attittudes and value systems is important for the development of responsive environmental management. Effective attitude measures already exist, most notably the New Environmental Paradigm scale. Since this measure was produced, however, certain issues not addressed by the scale have become increasingly important within the environmental debate. These include concepts such as the intrinsic value of nature, or the moral duties of humans to the rest of nature-issues that surface repeatedly in the environmental literature. The study has shown that it is possible to include references to the intrinsic value of nature, as well as the moral duties people have to the rest of nature and to other human beings, within a reliable and unidimensional attitude scale.  相似文献

The purpose of this simulation study was to assess the performance of latent variable models that take into account the complex sampling mechanism that often underlies data used in educational, psychological, and other social science research. Analyses were conducted using the multiple indicator multiple cause (MIMIC) model, which is a flexible and effective tool for relating observed and latent variables. The data were simulated in a hierarchical framework (e.g., individuals nested in schools) so that a multilevel modeling approach would be appropriate. Analyses were conducted accounting for and not accounting for the nested data to determine the impact of ignoring such multilevel data structures in full structural equation models. Results highlight the differences in modeling results when the analytic strategy is congruent with the data structure and what occurs when this congruency is absent. Type I error rates and power for the standard and multilevel methods were similar for within-cluster variables and for the multilevel model with between-cluster variables. However, Type I error rates were inflated for the standard approach when modeling between-cluster variables.  相似文献

There are unresolved tensions between achieving inclusivity and maintaining diversity in early childhood services in South Africa. While there have been substantial and impressive attempts to develop a comprehensive early childhood development policy as part of the new education planning in South Africa, there is a concern that indigenous traditions may be overlooked or lost in the process. Early childhood services, both governmental and those supported by non‐governmental organizations, have relied heavily,’ if not exclusively, on concepts and curricula drawn from Anglo‐American traditions. In order to illustrate these points this paper draws on material collected as part of a recent review of early childhood services in South Africa carried out for the Save the Children Fund.  相似文献

Recently China has been undergoing an unprecedented urbanisation process which has resulted in millions of rural families living in urban areas. As part of a study of Chinese migrant children's educational experiences, surveys and interviews were conducted with primary school teachers in a metropolitan city in East China. The objectives of this study were to describe teachers’ perceptions of migrant children's education in both migrant schools and in public schools, and to investigate differences in their beliefs between school types. Results found that urban teachers’ perceptions of educational inclusion of migrant students were slightly negative in general. However, teachers in public schools showed significantly more positive attitudes to inclusion of migrant students than migrant school teachers. In the light of these findings, the paper concludes with implications for practice and policy for education of migrant children in China.  相似文献

Government policy assumes that modernization and remodelling will be effective as external intervention mechanisms to improve job satisfaction. Based on data collected as part of the evaluation of the ‘Transforming the School Workforce Pathfinder Project’, an argument is presented here which suggests that internal management models may be more effective in improving teacher job satisfaction. By comparing the responses of teachers within primary and special schools with those from secondary schools, internal factors are identified which may be more relevant than externally imposed measures.  相似文献
