The purpose of this study was to investigate the effect of conceptual change texts accompanied with concept mapping instruction, compared to traditional instruction (TI), on 8th grade students understanding of solution concepts and their attitudes toward science as a school subject. Solution Concept Test was developed as a result of examination of related literature and interviews with teachers regarding their observations of students difficulties. The test was administered to a total of 64 eighth grade students from two classes of a general science course, taught by the same teacher. The experimental group received the conceptual change texts accompanied with concept mapping in a lecture by the teacher. This instruction explicitly dealt with students misconceptions. It was designed to suggest conditions in which misconceptions could be replaced by scientific conceptions and new conceptions could be integrated with existing conceptions. The control group received TI in which the teacher provided instruction through lecture and discussion methods. The results showed that conceptual change text accompanied with concept mapping instruction caused a significantly better acquisition of scientific conceptions related to solution concept and produced significantly higher positive attitudes toward science as a school subject than the TI. In addition, logical thinking ability and prior learning were strong predictors for the concept learning related to solution. 相似文献

ABSTRACTThe present study aims to examine the leadership research in higher education in order to shed light on its development during the last two decades by revealing the evolving trends in research on leadership in higher education, the most prominent scholars working on related research, the most popular topics in related research, and the countries in which the related studies are based. Bibliometric method was employed in the analysis of the original research and review papers published in five prominent higher education journals between 1995 and 2014: Higher Education, Research in Higher Education, Studies in Higher Education, The Journal of Higher Education and The Review of Higher Education. The results of this bibliometric analysis show that the majority of the related articles come from three countries: the U.S.A., the UK and Australia. It is also found that the leadership research in higher education is still very scarce and has not shown any meaningful increase during the last two decades. In addition, content analysis is used to provide more in-depth information about the topical focus, purpose and methodology of the selected articles. The results of content analyses are discussed in detail, and suggestions for the future research are provided. 相似文献

Current studies reveal that meta-level variables are very important in learning; however, little research has been devoted to the role of metaconceptual and meta-affective variables on student achievement. With the aim of filling this gap in the literature, the present study investigated the relationship between metavariables (metaconceptual awareness, metaconceptual regulation, affective awareness, and affective regulation) and science achievement with the mediating effect of science self-efficacy through structural equation modeling. A total of 576 eighth grade students participated in the study. Results indicated that science self-efficacy partially mediated the relationship that metaconceptual regulation and affective regulation have with science achievement. In other words, students who monitor and evaluate their existing conceptions and follow, control, and adapt their emotions are likely to have high science self-efficacy and then high science achievement. In addition, metaconceptual awareness, metaconceptual regulation, and affective regulation positively predicted science self-efficacy, which was itself a positive predictor of science achievement. The findings imply that metavariables are essential components of science achievement via self-efficacy. 相似文献

This study described the process of developing and validating the College Chemistry Self-Efficacy Scale (CCSS) that can be used to assess college students’ beliefs in their ability to perform essential tasks in chemistry. In the first phase, data collected from 363 college students provided evidence for the validity and reliability of the new scale. Three dimensions emerged: self-efficacy for cognitive skills, self-efficacy for psychomotor skills, and self-efficacy for everyday applications. In the second phase, data collected from an independent sample of 353 college students confirmed the factorial structure of the 21-item CCSS. The Cronbach alpha coefficients ranged from 0.82 to 0.92. In addition, each dimension of the CCSS had moderate and significant correlations with student chemistry achievement and differentiated between major and non-major students. Followed by the additional validation studies, the CCSS will serve as a valuable tool for both instructors and researchers in science education to assess college students’ chemistry self-efficacy beliefs. 相似文献

The purpose of this study was to develop a Meta‐Affective Trait Scale (MATS) to measure the meta‐affective inclinations related to emotions that students have while they are studying for their classes. First, a pilot study was performed with 380 10th‐grade students. Results of the exploratory factor analysis supported a two‐factor structure of the MATS, with 17 items and two dimensions (affective awareness and affective regulation). Second, in the validation study, the confirmatory factor analysis was carried out using data from 359 11th‐grade students. Satisfactory fit indices were obtained, providing evidence for the reliability and validity of the scale. Finally, for further evidence, a correlational analysis was run. Results indicated positive and significant correlations between learning strategies and self‐efficacy and the dimensions of the MATS. Consequently, the MATS can be employed by both researchers and teachers to assess students’ meta‐affective inclinations. 相似文献

This study aimed to explore pre-service chemistry teachers’ beliefs about constructivism and the influence of their beliefs
in their teaching practice. For this purpose, semi-structured interviews were carried out with eight pre-service teachers
in order to understand their belief structures. Pre-service teachers’ beliefs about constructivism were classified in three
categories which are weak, moderate, and strong conceptions of constructivism. For detailed exploration, three cases of pre-service
teachers representing these three categories were selected. The findings of this study showed that most pre-service teachers
in this study did not have a strong conception of constructivism and the relationship between the pre-service teachers’ beliefs
and their practice was not clear-cut. 相似文献
