实验在生物教学中占有十分重要的地位,通过实验不仅可以帮助学生加深对有关理论知识的掌握和理解,而且还可以培养和提高他们的观察能力、分析能力、思维能力和实践能力,是激发学生探索兴趣和创新精神的切入点,同时也能培养学生实事求是、严肃认真的科学态度。以高中《生物》(必修1)为例,实验课时数占了总课时数的1/4。这是为了改变长期以来以传授为主的局面,而开创的学生主动参与、探究发现、交流合作学习的新方式。新课改为高中生物实验教学提供了一个全新的舞台。在新课改背景条件下如何进行生物实验教学呢?下面笔者就这一问题谈谈体会。
Experiments play a very important role in biology teaching. Through experiments, students can not only help students master and understand relevant theoretical knowledge, but also develop and improve their observation ability, analytical ability, thinking ability, and practical ability. Explore the starting point of interest and innovative spirit, and at the same time, cultivate students’ realistic and serious scientific attitude. Take high school “Biology” (required 1) as an example, the experimental class hours accounted for 1/4 of the total class hours. This is to change the long-term situation in which teaching is the most important, and the students who initiate the initiative take part in, explore, discover, and exchange new ways of cooperative learning. The new curriculum was changed to provide a new stage for high school biology experimental teaching. How to conduct biological experiment teaching under the background of the new curriculum reform? The following author talk about this experience.
