生物化学是一门基础生命学科,从分子水平起步,探讨生命现象本质。是中职院校生物、食品、医学等专业学生必修的基础课程之一。因为教学内容中生物反应错综复杂,知识点繁多、其理论抽象复杂,令多数中职生感到难以理解和掌握,从而缺乏学习兴趣和积极性。致使学习效率较低,教学效果堪忧。本文结合实践教学经验,将PBL教学法在中职生物化学教学中的应用和心得归纳如下:一、PBL教学在生物化学中的重要性 Biochemistry is a basic life science, starting from the molecular level, to explore the essence of the phenomenon of life. It is one of the basic courses compulsory for students majoring in biology, food and medicine in vocational colleges. Because of the complexity of the biological response in teaching contents and the large number of knowledge points, the theoretical complexity is so complicated that most secondary vocational students find it hard to understand and master, thus lacking interest in learning and enthusiasm. Resulting in lower learning efficiency, poor teaching results. In this paper, combined with practical teaching experience, PBL teaching method in biochemistry teaching in secondary vocational education and experience are summarized as follows: First, PBL teaching in the importance of biochemistry
