化学是一门以实验为基础的自然科学。化学实验始终是化学教学的重要部分,是学生学习化学的重要环节,是化学学科探究的主要方式,是开发学生潜能、培养学生创新能力的有效途径。在中学化学教学中充分发挥化学学科的优势,进行化学探究实验设计练习,不但能巩固有关的化学知识和实验技能,而且能培养学生灵活的思维能力。一、探究实验设计中培养学生求异思维 Chemistry is an experiment-based science. Chemistry experiment is always an important part of chemistry teaching. It is an important link for students to learn chemistry, is the main way to explore chemistry subject, and is an effective way to develop students ’potential and cultivate students’ innovative ability. In the chemistry teaching of middle school, give full play to the advantages of chemistry subject and carry out chemical exploration experiment design practice, which can not only consolidate the relevant chemical knowledge and experimental skills, but also cultivate students’ flexible thinking ability. First, to explore students in experimental design seeking differences thinking
