有效教学的“三个认识”。校长和教师对有效教学务必要有清楚的认识,主要有如下三个方面。第一,把课上好是硬道理,也是教师的天职。但是硬道理也必须讲道理,所谓讲道理就是讲科学、讲观念、讲方法、讲技巧。第二,教学必须有效益。上课是一个教与学的过程,每一堂课就是每一级台阶,引导师生步步向上,因此每节课应该有每节成效,否则就是课时的浪费。第三,应该让教师因课堂而更加美丽起来。课堂教学效果是衡量教师业务能力的重要内容, Effective teaching “three understanding ”. Principals and teachers must have a clear understanding of effective teaching, mainly in the following three aspects. First, the best course is the last word, but also the teacher’s vocation. However, the last word must also be justified. The so-called reasoning is about science, concepts, methods and skills. Second, teaching must be effective. Class is a teaching and learning process, each lesson is every level, to guide teachers and students step by step, so each lesson should have the effect of each section, otherwise it is a waste of time. Third, teachers should be more beautiful because of the classroom. The effect of classroom teaching is an important measure of the professional ability of teachers.
