新课改形势下的教育,是把学习的内容拓展到了课前、延伸到了课后,这样给了学生很多的学习机会和发展空间。《化学》课程标准告诉我们,这是一门以青少年的生活为基础,以培养良好实验技能、乐于探究、热爱生活的新时代青少年为目标的活动型综合课程。学生的课前准备是教学活动的需要,也是培养学生自主学习能力和分析处理信息能力的重要手段,是培养学生探究能力的有效途径之一。学生可以在课前对这次活动主题进行相应的课前体验、资料搜集、准备素材等丰富多彩的活动。在教学实践中,我们经常能感受到学生的主体性地位,因为这门课程是以学生直接参与丰富多彩的实验、实践活动为主要教学形式去展开教学的。活动是课程的呈现形式,是课程实施的“灵魂”。所以,我们在设计课堂活动时就应该注意以下问题:

Pre-class preparation for students is a need for teaching activities. It is also an important means to cultivate students’ ability to study independently and analyze and process information. It is one of the effective ways to cultivate students’ inquiry ability. Students can perform various activities such as pre-class experience, data collection, and preparation of materials before the class.

The activity is the presentation form of the course and is the “soul” of the course implementation. Therefore, we should pay attention to the following issues when designing classroom activities:
