化学演示实验是化学课堂教学的重要教学方法之一,它能够直观的反映化学反应现象,揭示自然规律,调动探索的激情,提高学生的动手能力,符合学生的认知规律,符合新课程标准的理念。叶澜教授早就呼吁:让课堂充满活力。为提高化学演示实验的有效性,本文提出“互动式”化学演示实验设计方案以供参考。1仪器的选择仪器选择具有多样性,不是唯一的。传统的化学演示实验是教师就仪器讲仪器,忽略学生自主能力的提高,以及学生对仪器
Chemistry demonstration experiment is one of the important teaching methods in chemistry classroom teaching. It can intuitively reflect the phenomenon of chemical reaction, reveal the natural law, mobilize the passion of exploration, improve students ’abilities, meet the students’ cognitive rules and meet the requirements of the new curriculum standard idea. Professor Ye Lan has long called for the classroom to be full of energy. In order to improve the effectiveness of chemical demonstration experiments, this paper proposes an experimental design of “interactive” chemical demonstration for reference. 1 instrument selection instrument selection has a diversity, not the only one. The traditional chemical demonstration experiment is the teacher to talk about the instrument on the instrument, ignoring the improvement of students’ autonomous ability, as well as the students on the instrument
