长期以来,中学化学教学普遍采用传授式课堂教学模式,主要以解题训练为核心,注重“高密度、大容量、快节奏”的化学演练,而化学教学中概念的形成过程、规律的推导过程、化学文化的积淀过程普遍受到忽视,这种以解题为目标、以训练为手段的教学模式显然已经不能适应时代发展的需要。现代化学教育必须从过去以教师为中心、以教材为线索去传授机械性、模仿性、重复性的知识,转向以学生为中心、以问题为线索,使学生获取对未来至关重要的知识。认识的真正任务在于经过感觉而达到思维。教会学生学习,提高学习能力(尤其是思维能力),完善学生人格,为其终身全面发展奠基。我们采 For a long time, chemistry teaching in middle school has generally adopted the teaching mode of imparting classroom teaching, focusing on problem solving training as the core and paying attention to the chemical drills of “high density, large capacity and fast pacedness” and the formation process of concepts in chemistry teaching and regular The process of derivation and the accumulation of chemistry and culture are generally neglected. With the goal of solving problems, the teaching mode of training has obviously failed to meet the needs of the development of the times. Modern chemistry education must shift from teacher-centered teaching materials to mechanistic, mimetic and repetitive knowledge to student-centered and problem-based cues to enable students to acquire knowledge of the future. The real task of knowing lies in feeling and thinking. Teach students to learn, improve learning ability (especially thinking ability), improve student personality, lay the foundation for its lifelong all-round development. We adopt
