初中生物学“实验·探究”贴近生活的教学尝试——以“观察酵母菌和霉菌”为例

A Teaching Attempt of Life-Oriented “Experiment and Inquiry” in Junior High School Biology—A Case Study of “Observing Yeasts and Molds”

摘要: 初中生物学新课标高度关注学生贴近生活的实践经历。教材中“实验·探究”栏目的生活化设计能激发学生的兴趣、提高学生的科学探究能力。在“观察酵母菌和霉菌”的实验探究中，针对乡村中学实验条件比较差的现实，用安琪酵母、安琪甜酒曲和果冻培养基，将霉菌接种和制片合二为一，指导学生自主培养、制片和观察，提升学生的探索兴趣和生物学实践能力。

Abstract: The new curriculum standards for junior secondary school biology place great emphasis on students’ practical experiences relevant to their daily lives. The life-oriented design of the “experiment·inquiry” column in the textbook can stimulate students’ interest and improve their scientific inquiry ability. In the experimental inquiry titled “Observing Yeast and Mould”, taking into account the relatively poor experimental at rural secondary schools, Angel Yeast, Angel sweet rice wine starter, and agar medium were used to combine mould inoculation and slide preparation into a single step, guiding students to independently cultivate, prepare slides, and observe, thereby enhancing students’ interest in exploration and their practical biology skills.
