探究性学习可以使学生通过自己的主动探索来获取知识。将课本中的验证性实验设计为简单的探究性实验,符合学生的实际,也是当前学校条件可以实现的。笔者对高中生物一个重要的验证性实验“观察植物细胞的质壁分离和复原实验”进行了改进,实施了探究性实验教学设计并进行了教学实践和分析,旨在探讨如何培养学生的实验操作技能和探究能力。由此可以得出结论:开展探究性实验教学,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。学生对实验观察到的现象进行讨论和分析能够更好地发挥探究性学习的实效。
Inquiry learning enables students to acquire knowledge through their own active exploration. The verification experiment in the textbook is designed as a simple inquiry experiment, in line with the actual students, but also the current school conditions can be achieved. The author of an important high school biology confirmatory experiment “observation of plant wall plasmolysis and recovery experiment ” has been improved, the implementation of the experimental teaching design and teaching practice and analysis, to explore how to develop students Experimental skills and exploration skills. From this we can conclude that to carry out exploratory experiment teaching can not only cultivate students ’experimental operation skills through standardized experimental operations, but also develop students’ comprehensive inquiry ability and establish a scientific attitude of seeking truth from facts. Students to observe and analyze the phenomenon of the experiment to better explore the effectiveness of learning.
