一、明确教学目标,制定有效的教学策略(一)教学目标明确,教学才能有的放矢“DNA是主要的遗传物质”这一节课的内容主要是要让学生从肺炎双球菌的转化实验和噬菌体侵染细菌的实验两个实验中,体会科学家从实验材料的选择、研究思路的确定、技术手段的进步对研究过程所起的作用;训练学生由特殊到一般的归纳思维的能力,提高逻辑思维的能力;并从对遗传物质的探究历程中,领悟到科学的不断发展是要通过人们坚持不懈
First, a clear teaching objectives, the development of effective teaching strategies (A) a clear teaching objectives, teaching can be targeted “” DNA is the main genetic material "The main content of this lesson is to allow students from the pneumococcal transformation experiments and Bacteriophage infection experiments in two experiments, the experience of scientists from the choice of experimental materials, research ideas to determine the progress of technological means the role of the research process; training students from special to general induction of thinking ability to improve logic Thinking ability; and from the genetic material in the course of the exploration, the continuous development of science is through people persevere
