何谓“精讲”?叶圣陶指出:“一篇文章,学生也能粗略看懂,……深奥些的地方,老师必须指导一千,只需三言两语,能使他们开窍就行.”这“三言两语”,当然是要求教师以恰当、精简的语言讲在点子上.“多练”,练的形式很多,主要是指教师为完成教学目标、突出重点和突破难点而精心设计的各种形式的提问、练习等. Ye Shengtao pointed out: “An article, students can also be a rough understanding, ... ... esoteric places, the teacher must guide a thousand, only a few words to enable them to resuscitate on the line.” This “a few words” Of course, teachers are required to put their ideas in an appropriate and streamlined language in terms of “practice.” There are many forms of practice that mainly refer to teachers' various forms of questions and exercises designed to accomplish their teaching objectives, highlight priorities and overcome difficulties. Wait.
