基于学生化学学科核心素养的发展,根据中学有机化学模块的“相似相溶”原理,学生可自主设计与开展富有趣味性的“彩虹”实验,并在实验结束后进行课堂交流与教师总结。以趣味探究性实验的形式展现化学魅力,装置简易、操作方便,现象直观明显且多彩多样,能引起学生积极探索化学的兴趣,激发学生的想像力和思考力,集中发展化学学科“实验探究与创新意识”的核心素养。
Based on the development of core qualifications of students’ chemistry, students can independently design and carry out “Rainbow” experiments based on the principle of “similar compatibility” of organic chemistry modules in secondary schools, and conduct classroom exchange after the experiment Teacher summary. It shows the chemical charm in the form of interesting exploratory experiment. The device is simple and easy to operate. The phenomenon is intuitive and colorful. It can arouse the interest of students in actively exploring chemistry, stimulate students’ imagination and thinking ability, and concentrate on the development of chemistry subject. Innovation consciousness "core literacy.
