高中化学元素化合物教学策略的实践研究

On the Strategies for Teaching High School Chemical Compounds

针对元素化合物实际教学过程中出现的问题,提出通过创设真实的问题情境,以问题导学教学模式组织教学;设置合理的教学目标,控制教学深广度;同时运用概念图思想帮助学生自主构建元素化合物知识网络;帮助学生进行有效建模,提高思维的品质,进而使零散的知识系统化、条理化、结构化、网络化的教学策略。

Focusing on the problems that appear in teaching element compounds, this paper suggests that the teaching be done by means of creating real situations and by using the teaching model of problem-oriented learning; that reasonable objectives of teaching be set to control the depth and width of teaching; that concept maps are used to help students construct the knowledge network of element compounds by themselves; and help students to build models effectively so as to improve the quality of thinking, thus making the fragmented knowledge become systematic, well-organized, structured, and network-based.
