Abstract:

The problem-based learning （PBL） teaching model is a problem-oriented heuristic teaching method that conforms to the requirements of the times. The PBL teaching model can overcome the drawbacks of the traditional “cramming” teaching model， fully tap into students' subjectivity， stimulate their learning enthusiasm， and cultivate their ability to solve practical problems， collaborate in teams， and innovate. This article takes the chapter on halogens in inorganic chemistry as a teaching example to explore the application of PBL teaching mode in inorganic chemistry teaching. The study found that the PBL teaching mode leads to teaching content through questions， allowing students to independently explore and learn around teaching difficulties. It helps to cultivate students' group cooperation awareness， communication and expression abilities， and the ability to use chemical knowledge to solve practical problems.

Key words: Problem-based learning teaching mode, Inorganic chemistry, Group collaboration
