The aim of the article is to provide teachers some ideas about thedevelopment of physical knowledge and to make them more receptive to thedifferences between their and the students thinking. I want to show, thatthese differences lie not only in the richness of experience, but also in thestructure of this experience. I try to point to some of these differenceslying in the content, form and meaningfulness. The article is based on anadapted version of Piaget's model of the growth of physical knowledge. Themodel represents the changes of semantic understanding, formal language andlogical structure of a theory during its historical development. I illustratethe model on the development of classical mechanics, but similar changes canbe found also in the history of electrodynamics or quantum mechanics. Thecentral idea of the paper is to use this model of the historical developmentof physical knowledge in analysis of the cognitive processes in physicseducation. 相似文献

理解MOOC平台学习者的动机结构和基本特点是提升MOOC平台建设质量和学习质量的基础性工作。文章以中国最大的MOOC平台之一——"学堂在线"学习者为研究对象,通过机器学习的方法,对中国MOOC学习者自填的动机文本进行分析。结果表明,中国MOOC学习者学习动机可以分为三类九种。其中,稳定型学习动机包括认知兴趣、提升自我和习惯性学习三种取向;实用型学习动机包括职业发展、补充学习和外界影响三种取向;尝鲜型学习动机包括优质资源、新型学习和人际交往三种取向。稳定型特别是认知兴趣取向的学习动机占比最高,反映出在线学习目前是一种自主性、非制度性的学习方式,以满足个体非功用性需求为主。MOOC学习动机和过程性学习质量之间的关系,还有待进一步探索。 相似文献

The purpose of this study was to explore how Year 8 students answered Third International Mathematics and Science Study (TIMSS) questions and whether the test questions represented the scientific understanding of these students. One hundred and seventy-seven students were tested using written test questions taken from the science test used in the Third International Mathematics and Science Study. The degree to which a sample of 38 children represented their understanding of the topics in a written test compared to the level of understanding that could be elicited by an interview is presented in this paper. In exploring student responses in the interview situation this study hoped to gain some insight into the science knowledge that students held and whether or not the test items had been able to elicit this knowledge successfully. We question the usefulness and quality of data from large-scale summative assessments on their own to represent student scientific understanding and conclude that large scale written test items, such as TIMSS, on their own are not a valid way of exploring students' understanding of scientific concepts. Considerable caution is therefore needed in exploiting the outcomes of international achievement testing when considering educational policy changes or using TIMSS data on their own to represent student understanding. 相似文献

如果你不小心,使餐桌上的盘子从桌子边缘掉了下去,你会发现盘子在空中翻180°,覆在地上。这是偶然的吗?如果你反复试几次,结果盘子掉地时总是覆在地上。你再改用其他扁平物体,长度大约在10到30厘米,比方说书、碟子什么的,如果你轻轻地将它推离桌面,向地上掉下去,它们总是在空中正好翻个个儿,背朝天地覆在地上。这其中有什么道理呢? 相似文献
