教师在课堂教学中贯彻“目的简明”、“讲演简要”、“练习简单”的原则,引导学生进入“成功→兴趣→问题→努力→成功→……”如此一个积极的递进螺旋中,是能够取得良好教学效果的。“目的简明”是将课时总目的分解为苦干个易于实施的“子目的”。“子目的”的设定,一要适合于同学的认识层次,二要适合于同学的能力层次,使相继“子目的”实施时,有如“多米诺”骨牌似的体现连续性和相关性。“讲演简要”是讲述和实验演示都要围绕“子目的”而展开,让同学能迅速达到“子目的”的要求。“练习简单”是指导课堂提问、黑板练习、课堂小测验等教学信息反馈
Teachers implement the principles of “conciseness of purpose”, “briefing is brief”, and “practice is simple” in classroom teaching, and guide students to enter such a positive progressive spiral as “success, interest, problem, effort, success, ...”. Can achieve good teaching results. The purpose of “conciseness” is to decompose the general purpose of class hours into an easy-to-implement “sub-purpose.” The setting of “sub-purposes” must be appropriate to the level of understanding of the students. Second, they must be suitable for the ability level of the students. When the “sub-purposes” are implemented in succession, they are like “domino” dominoes to show continuity and relevance. “Speaking briefly” means that both the narrative and the demonstration must be carried out around “sub-purposes” so that the students can quickly meet the requirements of “sub-purposes.” “Simple Exercise” is a guide to classroom questions, blackboard exercises, classroom quizzes, and other teaching information feedback
