摘要
介绍了大学无机化学课堂中"原电池"部分的教学实践。通过启发-探究式教学模式,启发学生把常见的氧化还原反应,经过不断的设问和探究,最终设计成原电池,实现了通过原电池装置来证实氧化还原反应发生了电子传递的教学目的。学生在教师的启发下探究、分析、推导、创新和修正,使学生清晰地认识到知识的前后逻辑关系,对氧化还原反应概念、原电池装置有更深刻的理解,培养了学生的科学辩证思维能力。
This paper introduces the teaching practice of the primary battery part in inorganic chemistry class. Through the heuristic-inquiry teaching method, students are inspired and induced to design the common redox reactions into primary batteries after constant questioning and improvement, to achieve the teaching purpose that the redox reaction does have electron transfer by the primary battery device. Students explore, analyze, deduce, innovate and revise the device of primary battery in teacher’s inspiration, it can make students clearly know the logical relationship of the concept of redox reaction and primary battery device. At the same time, the students’ ability of scientific dialectical thinking is cultivated.
