化学是一门以实验为基础的学科,在化学教学中,如何选好实验,做好实验,充分发挥实验的探究功能,培养学生的科学探究能力,应是每位化学教师教学研究的重要课题。一、创设实验活动情景,引导学生自主探究实验能帮助学生认识和理解科学的发现过程,培养学生的创造性思维。因此,教师要尽可能地创设实验,引导学生自主探究。例如,在进行“二氧化碳制取与研究”教学时,首先引导学生对比分析 Chemistry is an experiment-based discipline. In chemistry teaching, how to choose experiment, experiment, give full play to the exploratory function of experiment and develop students’ ability of scientific inquiry should be an important subject for every chemistry teacher’s teaching and research . First, the creation of experimental activities to guide students to explore their own experiments can help students understand and understand the discovery process of science, develop students’ creative thinking. Therefore, teachers should try to create experiments to guide students to explore. For example, in conducting the “carbon dioxide preparation and research” teaching, first of all guide the students comparative analysis
