元素化学知识零散,学生易学易忘,但它又是各种化学知识的重要载体.研究和把握正确的复习方法,不仅可提高其复习的有效性、而且有利于学生的知识整合.本文就从理论分析和实践操作两个层面上来研究高中复习课程中,教师如何引领学生将元素知识与理论、实验、制备和用途等契合为立体知识,以期突破元素复习这一教学难点.
However, it is also an important carrier of all kinds of chemical knowledge.Researching and grasping correct reviewing methods can not only improve the effectiveness of the review, but also help the students to integrate their knowledge. Theoretical analysis and practical operation of the two levels to study high school review curriculum, teachers how to lead students to the elemental knowledge and theory, experiment, preparation and use fit into the three-dimensional knowledge, in order to break through the elemental review of this teaching difficulty.
