一、教材分析人教版高中选修1《生物技术实践》的探究加酶洗衣粉的洗涤效果的实验,是倡导探究性学习、发展探究能力的良好素材.探究加酶洗衣粉和普通洗衣粉去污能力有无差别,是让学生通过探究活动自主发现加酶洗衣粉的洗涤效果的影响因素等问题.探究加酶洗衣粉和普通洗衣粉去污能力有无差别重在引导.二、教学目标1.知识目标:通过探究实验,能理解酶具有专一性,酶的催化作用易受多种因素的影响.2.能力目标:(1)具有初步的探究能力,会提出问题、做出假设.(2)尝试设计实验方案,独立完成实验,锻炼并运用逻辑思维能力.
First, the textbook analysis PEP teach high school elective 1 “biotechnology practice” to explore the effect of enzyme washing detergent washing effect is to promote inquiry learning, development of good ability to explore the material to explore the enzyme plus detergent and detergent to ordinary There is no difference between sewage capacity, is to allow students to explore through independent research found that the impact of enzyme washing detergent washing effect and other issues to explore the enzyme detergent and ordinary detergent decontamination priority whether there is any difference in the guide. 1. Knowledge Objectives: By exploring the experiment, it can be understood that the enzyme is specific, and the catalytic effect of the enzyme is easily affected by many factors.2.Capacity Objectives: (1) Have preliminary inquiry ability, ask questions and make assumptions (2) Try to design experiment plan, experiment independently, train and use logical thinking ability.
