1引言笔者在职业中学从事教学工作,发现了这样一个现象:有些老师对板书的的重要性认识不够。或满天繁星,不得要领;或字迹潦草,难以辨认;或干脆不写一字,黑板光光。究其原因:有的说职高学生学习积极性不高,写了作用不大,浪费心血;有的说这里的学生应该重实践技能的掌握,理论没必要死记,实践也能掌握知识;有的说讲课讲课,上课主要是笔者讲你听……究其实质,就是板书重要性认识不足。 1 Introduction The author engaged in teaching in vocational schools, found such a phenomenon: Some teachers do not understand the importance of the blackboard. Or starry sky, not essentials; or illegible, illegible; or simply do not write a word, blackboard light. The reason: Some said vocational high school students enthusiasm is not high, wrote a small role, waste of effort; some say here students should practice skills master, theory no need to remember, practice can also master the knowledge; some say Lecture lectures, the main class is the author tell you to listen ... ... The essence of the study, is the lack of understanding of the importance of the blackboard.
