一、教学思路该课题是浙科版高中生物学必修模块3《稳态与环境》第1章植物的激素调节中的“探究活动”内容,既是学习的重点,也是学习的难点。该探究活动是依据生长素作用的特点具有两重性的原理,以生长素的发现、生长素的生理作用及其应用等知识作为背景,引导学生如何将科学理论应用于生产实践,学生可体验到科学研究的一般过程,同时也是训练学生将实际问题转化成可行的实验方案的逻辑思维能力,从而提高设计实验方案的可行性、 First, the teaching ideas The subject is Zhejiang Science High School Biology Compulsory Module 3 “Steady State and Environment” The first chapter of plant hormone regulation in the “exploration activity” content, is not only the focus of learning, but also learning difficulties. The exploration activity is based on the principle of duality with the principle of auxin. With the discovery of auxin, the physiological function of auxin and its application as background, the research guide students how to apply scientific theories to production practice, and students can experience science The general process of research, but also to train students to practical problems into a logical experiment of the logical thinking skills, thereby enhancing the feasibility of designing experimental programs,
