本章材料丰富、内容繁多，一节课时用“模型、挂图、标本”等教具按常规教学手段进行教学，不但教学模式陈旧，而且课堂时间紧迫，教师疲于匆忙完成教学过程，教学效果不理想。笔者编制了“爬行纲”这一章的多媒体教学课件，通过“文、图、形、色、声、动画”等形式，变静为动 This chapter is rich in materials and content. During the first lesson, teaching materials such as “models, wall charts, and specimens” were used to teach according to conventional teaching methods. Not only the teaching model was outdated, but also the classroom time was short. Teachers were tired of rushing to complete the teaching process, and the teaching results were not satisfactory. The author has compiled the multimedia teaching courseware of the chapter “Reptilia,” through the forms of “text, drawing, shape, color, sound, and animation”.
