上期学习进程研究专题向大家介绍了由“做中学”科学教育改革实验项目教学中心为总课题组开展的5个子课题中的2个爬梯式学习进程研究,本期将介绍3个拼图式学习进程——“分子原子理论”“遗传”“生物多样性”的研究情况及成果。拼图式学习进程较爬梯式更为普遍,它是横向的,而非纵向;它是网状的,而非线性;较大的概念是从较小的概念逐步扩展而形成的,通过逐步完善局部而建构整体的方式获得对知识的理解。从某 The previous study on the topic of learning process introduced to you by the “science” science education reform pilot project teaching center for the general task force to carry out five sub-topics in the two ladder learning process, this issue will introduce three puzzle Learning Process - Research Status and Achievements of “Theory of Molecular Atoms ” “Genetics ” “Biodiversity ”. The puzzle learning process is more common than the ladder-climbing style. It is horizontal rather than vertical. It is reticular rather than linear. The larger concept is formed by the gradual expansion of smaller concepts. By gradually improving the local The overall way to build understanding of knowledge. From a
