创新微实验提升中学生化学逻辑建构能力的策略研究

Research on the Strategies of Innovating Micro Experiment to Improve the Ability of Middle School Students to Construct Chemical Logic

化学微实验可以使学生以较少的化学试剂、简单的仪器设备、具体的问题进行实验,其具有微型化、可操作性和探究性强的特点,有利于学生更好地开展自主学习。创新微实验教学模式,能帮助学生把化学知识和实验有机结合,更好地理解化学理论知识,培养学生的化学学科核心素养。教师可通过微实验设计与应用,用“自助式”“嫁接式”“类比式”“比对式”等模式的微实验提升学生化学逻辑建构能力。

Chemical micro experiment can enable students to carry out experiments with fewer chemical reagents,simple instruments and equipment,and specific problems.It has the characteristics of miniaturization,operability,and strong inquiry,which is conducive to students'autonomous learning.Innovating the teaching mode of micro experiment can help students organically combine chemical knowledge with experiment,better understand chemical theoretical knowledge,and cultivate students'core quality of chemistry.Through the design and application of micro experiments,teachers can use"self-service","grafting","analogy","comparison"and other micro experiments to improve students'ability to construct chemical logic.
