学生在总复习时,面对浩翰的生物学知识,常常感无从下手。我在教学中依据学生认知水平的六个层次(识记、理解、应用、分析、综合、评价)设计出“点、线、面”三层次复习法,经较长时间探索,取得了良好效果。“点、线、面”是不同层次的知识。“点”的知识,即知识点;“线”的知识,指知识的纵向联系;“面”的知识是在纵向知识的基础上横向扩展,形成纵横交错的多维知识体系。“点”是基础,“线”是提高,“面”是深 When students review the biological knowledge of the Han people during the general review, they often feel that they have no way to start. In the teaching, I designed a three-level review method of “point, line, and face” based on the six levels of student cognitive level (recognition, understanding, application, analysis, synthesis, and evaluation). After a long period of exploration, I achieved good results. effect. “Points, lines, and faces” are different levels of knowledge. The knowledge of “points” is the knowledge point; the knowledge of “line” refers to the vertical connection of knowledge; the knowledge of “face” is expanded horizontally on the basis of vertical knowledge, forming a criss-crossing multidimensional knowledge system. “Point” is the basis, “line” is raised, and “face” is deep
