水硬度测定实验项目化教学实施浅谈

Using Project-based Learning in Determination of Water Hardness Experiment

介绍水硬度测定实验项目化教学实施方案,分析其优缺点。对于水硬度测定实验的项目化教学,课前学生查阅资料准备方案,教师审核方案;课中学生实施项目,教师进行观察记录;课后学生总结评价,教师补充完善。水硬度测定实验的项目化教学可以提高学生自主学习能力,但是该教学模式对学生要求高,花费时间多,对教师要求也高,是否实施需要综合考虑。

The teaching implementation of project of determination of water hardness experiment was introduced. The advantages and disadvantages of teaching by project were analyzed needed to get ready to experimental program before class. And teachers audited programme. Teachers also observed and recorded the situation in class while students performed the project. Finally they evaluated the project with teachers. And teachers gave more good advice. The teaching by project could improve the students' autonomous learning ability. But it brought forward new demands for students. The class needed more time. Teachers needed to meet the new requirements. Whether to implement the model teaching depended on the school comprehensive strength.
