在以往的教学过程中,如果只使用多媒体,学生往往由于对一节课的整体认识不够,找不到知识的主线,而学案一般都是一节课的内容成层次性出现,所以可以帮助学生很好地理解教师提出的某一环节的问题,促进师生互动,而且使学生学习的思路比较清晰,在课后复习的过程中,也可以明确知识的脉络。将多媒体与学案教学有机地结合起来,能有效地提高课堂效率。
In the past teaching process, if you only use multimedia, students often can not find the main line of knowledge due to the lack of understanding of the whole lesson and the case study is usually a hierarchical content of the class, it can help Students have a good understanding of the problems raised by teachers and promote the interaction between teachers and students. Students are also given a clearer idea of what to learn and can also clarify the context of their knowledge after class review. Multimedia and case teaching organically combine, can effectively improve the efficiency of the classroom.
