摘要:

在无机化学6s2惰性电子对效应教学过程中,提出"理论性、直观性和规律性"教学三原则,使学生在较为轻松的氛围中理解和掌握该概念,成功化解了教学过程中知识点分散、学习难度大与学生理解力间存在的差距。同时,培养了学生综合归纳和发现问题、解决问题的能力,使大一新生感受到大学化学知识的系统性,对解决问题方法的学习及能力培养的重要性。

Abstract:

During the teaching process of 6s2 inert pair effect in the course of inorganic chemistry, three teaching principles, "theorization, intuition and regularity", have been proposed accordingly. By using these principles, students can understand and master the concept of 6s2 inertia pair effect in a relatively relax atmosphere. In addition, the gap between the widely spread knowledge points as well as the difficulty of learning and the understanding ability of the students is reduced successfully. Meanwhile, the use of these principles is very helpful to cultivate students' abilities of comprehensive induction, and finding and solving problems, which can make the students feel the importance of systematicness of knowledge, methodology of solving problems and the ability training.
