高中生物探究式实验教学设计研究及案例分析

“探究式学习”促使学生的学习方式和教师的教学方式发生深刻的变革.阐述了探究式学习、实验操作技能和探究式实验教学模式这三个概念的内涵.同时,对高中生物一个重要的验证性实验“叶绿体中色素的提取和分离”进行了改进,实施了探究式实验教学设计并进行了教学实践以及分析,旨在探讨如何培养学生的实验操作技能.由此可得出结论:开展探究式实验教学,既能通过规范的实验操作,培养学生的实验操作技能,又能培养学生的综合探究能力并树立实事求是的科学态度;利用随堂式的实验教学评价,能很好发挥探究式学习的成效.

Research on Teaching Design and Case Analysis for Exploratory Experiment of Senior Biology

The deep reformation about learning mode of students and teaching mode of teacher are promoted by exploratory study.The thoughtfulness of exploratory study,experimental operation skills and exploratory experimental teaching mode are expounded.At the same time,the typical case of experiment of senior biology is selected,and the programme of exploratory teaching design is made.The programme is analyzed and put into practice as well.How to cultivate students'ability of experimental operation skills is discussed.It could be concluded that it is not only cultivates students'ability of experimental operation skills to carry out exploratory experimental teaching,but also fosters students'scientific attitude and practical and realistic spirit;The exploratory study is effective that evaluation of experimental teaching is given by classroom discussion.
