生物作为中学阶段的一门必修课程,其重要性总会或多或少地受到学校及学生的忽视,给课堂教学带来一定的难度与困惑。我们生物教师就应想方设法地提高课堂教学的趣味性、系统性和条理性,充分利用现代媒体、先进的教学方法,把传统媒体与现代媒体有机结合,各展其长,互为补充,达到教学的优化和组合。根据教学设计的程序、模式及多媒体组合教学的设计与应用,笔者略谈浅见,与广大生物教育工作者共勉。一、划分知识点,确定教学目标教学目标划分为三个水平层次:了解、理解、掌握。既将每一节课的知识内容划分为若干知识点,又确定了每个知识点所要达
Biology, as a required course in secondary school, is always more or less neglected by schools and students, bringing some difficulties and confusion to classroom teaching. Our biological teachers should try their best to improve the interesting, systematic and systematic teaching in class, make full use of the modern media and advanced teaching methods, combine the traditional media with the modern media, develop their own strengths and complement each other to achieve teaching Optimization and composition. According to the teaching design of programs, models and multimedia portfolio teaching design and application, the author briefly talked about, with the majority of biological education workers alike.
