新编中学化学教学大纲(试行草案)指出:“化学教学要采用启发式,引导学生积极主动地学习,以培养他们独立思考和自学的能力。”这就明确地指出了要进行启发式教学,其目的是要让学生掌握双基(基本知识、基本理论),发展智力,培养能力。这个问题提得很重要。长期以来,我国化学教学比较习惯于教师讲、学生听以及实验论证、重 The new middle school chemistry syllabus (protocol draft) states: “The chemistry teaching should use heuristics to guide students to actively and actively learn to develop their ability to think and study independently.” This clearly indicates that heuristic teaching should be conducted. Its purpose is to allow students to master dual-basic (basic knowledge, basic theory), develop intelligence, and develop abilities. This question is very important. For a long time, chemistry teaching in our country has been more accustomed to teachers’ speaking, students’ listening, and experimental arguments.
