基于Parsel理念的初中化学教学实践与反思——以“二氧化碳的性质和用途”为例

Junior High School Chemistry Teaching of“Properties and Uses of Carbon Dioxide”Based on Parsel Ideas

基于Parsel理念,以二氧化碳为载体,正确定位教学目标,改变教学环节,转变教学策略,创设贴近生活的情境,重视评价反馈,引导学生在情境感知、问题解决和探究实践中有效提升科学素养。研究发现,基于Parsel理念的初中化学教学实践应关注3个方面:应创设贴近生活的情境吸引学生;以高质量的问题引发思考;以多样化的活动助推探究实践。

Based on the concept of Parsel,with carbon dioxide as the carrier,we should correctly position the teaching objectives,change teaching links,change teaching strategies,create close to life situations,pay attention to evaluation feedback,and guide students to effectively improve their scientific literacy in situational awareness,problem solving and inquiry practice.It is found that junior high school chemistry teaching practice based on Parsel concept should pay attention to three aspects:first,create a situation close to life to attract students;the second is to arouse thinking with high quality problems;the third is to promote inquiry practice with diversified activities.
