一、问题的提出在原有的教育、教学条件下,长期以来以“讲解式教学”、“接受性学习”为主,教师往往把教学理解为讲解知识、技能、概念、原理,而许多学生的学习则仅仅立足于被动地接受教师的传输知识,偏重于机械记忆、浅层理解和简单应用,学习成了简单的、模仿和大量的做题。针对这一状况,当前教学改革的一个重点就是通过教学目标、内容和方法的调整,改变原有教师单纯灌输式的教学方式和学生单纯接受式的学习方式,在开展有效的接受学习的同时,形成一种对知识进行主动探求,并重视解决实际问题,重视应用的主动积极的学习方式。在新一轮课程改革当中,许多教师把新的教学思想注入到课堂教学,取得了初步成效。但化学理论的教学,由于其理论性强,内容抽象,学生难于理解,教学难度大,教师在进行教学改革时往往裹足不前,认为这一类型的内容不适合学生去主动 I.
