所谓“方、原”是指教学方法和教学原则,主要讲述教学方法、教学原则的综合运用和创新。以电气专业中的电工基础、电气识图、单片机应用三门课程的教学为例,分析研究各学科各章节的教学需要,选择最优的教学方法、结合科学的教学原则,并以此实践为例,提倡广大职业教育工作者注重教学方法、教学原则的研究和选择,不断提高自身的教学水平,将“两学”原理广泛应用于教学实践中。 The so-called “square, the original ” refers to the teaching methods and teaching principles, mainly on teaching methods, teaching principles and the comprehensive utilization and innovation. Taking the teaching of electrician’s basic, electrical knowledge map and single-chip microcomputer application in three courses as an example, this paper analyzes and studies the teaching needs of all chapters, selects the best teaching method, and combines the scientific teaching principles, For example, the majority of vocational education workers are encouraged to pay attention to the study and selection of teaching methods and teaching principles, and constantly improve their teaching level so as to apply the principle of “two learnings” to teaching practice.
