在高中化学教学中,问题情境可以促使学生积极思考,引导学生就某一问题进行逐层深入探究。可以作为问题情境的素材很多,如课内外实验、生活故事、化学史实、实践活动、热点新闻等,充分合理地运用好问题情境,可以激发学生的思维,搭建知识、技能和日常体验的桥梁,完成对知识的重构过程。一、化学实验是创设问题情境的优质资源实验是化学学科必不可少的一项教学活动。化学实验分为演示实验和探究实验。教师在课堂教学过程
In high school chemistry teaching, the problem situation can prompt students to think positively and guide the students to inquire deeply on a certain issue. As a matter of fact, there are a lot of materials that can be used as problem situations, such as in-class and out-of-class experiments, life stories, historical facts of chemistry, practical activities and hot news. The full and reasonable use of problematic situations can arouse the students’ thinking and build a bridge of knowledge, skills and daily experience. Complete the reconstruction process of knowledge. First, the chemical experiment is to create a quality environment for the problem situation Experiment is an essential teaching chemistry activities. Chemical experiments are divided into demonstration experiments and exploration experiments. Teachers in the classroom teaching process
