交互式电子白板以其操作便捷、内容丰富、趣味性强等特点深受一线教师的青睐,在教学中的辅助作用很明显:可以创设情境,寓乐于教,化静为动,突破难点,延伸教学,让学生爱学、乐学。但是,它也是一把双刃剑,由于课堂容量大、知识的生成过程、学生的阅读空间和主体地位没有得到很好落实等问题,学生容易成为课堂的看客。若片面追求、滥用,就会成课堂的“绊脚石”。 The interactive whiteboard is favored by front-line teachers for its convenient operation, rich content, and strong interest. The supporting role in teaching is obvious: it is possible to create contexts, retreat to teach, turn silence into action, break through difficulties, and extend. Teaching, let students love learning and learning. However, it is also a double-edged sword.

If one-sided pursuit and abuse, it will become a “stumbling block” in the classroom.
