高中生物课程标准明确选修1模块是实验课,苏教版选修1“生物技术实践”第三章第一节“酶的制备和应用”编排了“酶活力的测定”、“洗涤剂中常用的酶制剂”两部分内容。“酶活力的测定”教学内容设计以“制备果胶酶并观察其作用”实验教学设计为主线。在教师的指导下,引导学生自学有关“酶”的基础知识,在此基础上设计实验方案并完成实验过程。“制备果胶酶并观察其作用”实验分为“制备果胶酶”和“观察果胶酶的作用”两部分实验内容,2个实验可 The module of high school biology curriculum is clearly selected 1 module is the experimental class, the Sujiao version of the elective 1 “biotechnology practice ” chapter III of the first chapter “preparation and application of enzyme ” arrangement “determination of enzyme activity ”Detergent commonly used enzyme “ two parts. ”Determination of enzyme activity “ teaching content design ”Preparation of pectinase and observe its role “ experimental teaching design as the main line. Under the guidance of teachers, students should be guided to learn the basic knowledge of ”Enzyme“, on the basis of which, the experimental scheme is designed and the experiment process completed. ”Preparation of pectinase and observe the role of “ The experiment is divided into ”Preparation of pectinase “ and ”Effect of pectinase observation " two parts of the experiment, two experiments
