The purpose of this study was to examine the relations between primary school students’ conceptions of, approaches to, and self-efficacy in learning science in Mainland China. A total of 1049 primary school students from Mainland China participated in this study. Three instruments were adapted to measure students’ conceptions of learning science, approaches to learning science, and self-efficacy. The exploratory factor analysis and confirmatory factor analysis were adopted to validate three instruments. The path analysis was employed to understand the relationships between conceptions of learning science, approaches to learning science, and self-efficacy. The findings indicated that students’ lower level conceptions of learning science positively influenced their surface approaches in learning science. Higher level conceptions of learning science had a positive influence on deep approaches and a negative influence on surface approaches to learning science. Furthermore, self-efficacy was also a hierarchical construct and can be divided into the lower level and higher level. Only students’ deep approaches to learning science had a positive influence on their lower and higher level of self-efficacy in learning science. The results were discussed in the context of the implications for teachers and future studies. 相似文献

In this study, we have synthesized the research on visualization and representation to propose a model consisting of 4 major components of visualization competence in learning science: constructing, interpreting, transforming, and critiquing visualizations. We have developed and validated an assessment that measures students’ visualization competence of matter (VCM). We administered the VCM assessment to 762 7th to 12th grade students at 2 public high schools in Taiwan. The students had started to learn concepts of matter at the particulate level in the 7th grade. However, traditional assessments rarely measure students’ visualization competence in science. It was therefore unclear how well the students performed on visualization of matter across grade levels. Overall, the results indicated that the students’ visualization competence of matter improved as they advanced to higher grades. A significant factor accounting for the development of their visualization competence of matter is their course experience, not their age or gender. We also found that content knowledge plays only a conditional role in students developing visualization competence of that content. Implications and future studies are discussed. 相似文献

The Catch Up Programme is a literacy intervention designed for children who are behind with reading at the start of Year 3 (7 to 8 year‐olds). This paper describes pilot research that informed the project in its early stages of development, and the findings should therefore be treated with caution. The reading progress of a sample of 74 Catch Up pupils from 15 schools in three local education authorities was measured. This showed a considerable increase in pupils’ reading ages across a 10 week period. A smaller experimental study was also carried out in nine Oxfordshire schools (48 pupils) to compare a Catch Up sub‐sample with a Matched Time group and a Control group. Findings showed that the Catch Up pupils made considerably more progress during the same period than both the other groups. 相似文献

逻辑学面临的危机和挑战迫使逻辑学界重视逻辑学的应用问题.但是,逻辑应用又依赖于逻辑学的发展.有了"有用的逻辑".才能有"逻辑的有用".中国人从古到今使用的都是辩证逻辑,但还有强要把辩证逻辑用一套符号系统科学地刻画出来,并应用于教学.当前逻辑学界需要把主要精力放在辩证逻辑和或然逻辑的研究方面.促其成熟,并应用于教学,这样才能改变"逻辑学无用"的局面. 相似文献

This study investigated the prospective relationships between reading performance and reading habits among Finnish children during the first and second grades of primary school. One hundred and ninety‐five children were examined twice during their first primary school year and once during the spring term of Grade 2. The results showed, first, that children's reading skills predicted their reading habits: the more competent in reading children were at the end of Grade 1, the more likely they were to engage in out‐of‐school reading one year later. Second, reading habits also predicted reading skills: the amount of out‐of‐school reading at the end of Grade 1 contributed to the development of word recognition skills. 相似文献
