在现代数学教学中,板书是课堂教学不可或缺的部分,而多媒体则能有效提高学生学习兴趣进而提升教学效果。随着信息技术的发展,多媒体教学似乎将不可逆转的替代传统板书教学,但多媒体的滥用,不仅不能优化课堂教学,反而分散学生的注意力,浪费教师的大量精力。那么上述二者应该如何在课堂中使用呢?一、黑板板书与多媒体的特点分析黑板板书直观,准备相对简单,尤其是在解题规范上,教师一边口授一边板书,节奏较慢,学生容易印象深刻。且 In modern mathematics teaching, writing a book is an indispensable part of classroom teaching, and multimedia can effectively improve students’ interest in learning and thus improve teaching effectiveness. With the development of information technology, it seems that multimedia teaching will irreversibly replace the traditional teaching of the traditional blackboard. However, the abuse of multimedia not only can not optimize the classroom teaching, but distract the students’ attention and waste a lot of energy from the teachers. So the above two should be used in the classroom it? First, the characteristics of blackboard board and multimedia analysis Blackboard board intuitive, preparation is relatively simple, especially in the problem-solving norms, while teachers dictate the side of the blackboard, slow pace, students easy impression profound. And
