1、设计思路“基因突变”是高中生物的核心概念之一,高中生物课程标准提出了明确的要求“倡导学生在解决实际问题的过程中深入理解生物学的核心概念”。因此在实际的教学过程中,利用工具让学生自己动手去进行模拟基因的剪拼等改变,并通过进一步的书写对应的m RNA片段和肽链上的氨基酸排列序列,去直观的体会基因突变的实质和影响。2、教学分析本节内容要落实的高中生物学课程内容标准是:“遗传与进化”模块中“生物的变异”主题下的“举例说明基因突变的特征和原
1, design ideas ”gene mutation “ is one of the core concepts of high school biology, high school biology curriculum standards set out a clear requirement ”advocate students in the process of solving practical problems in-depth understanding of the core concepts of biology “. Therefore, in the actual teaching process, the tool is used to let the students do the change by themselves, such as cutting the spell of the mimic gene and further understanding the sequence of the amino acid sequence in the m RNA fragment and the peptide chain Substance and impact 2, Teaching Analysis The contents of this section of high school biology curriculum to be implemented is: ”genetic and evolution “ module ”biological variation “ under the theme of ”to illustrate the characteristics and gene mutation
