科学学习要以探究为核心,而科学探究必须以科学实验为基础,课堂实验是学生开展探究活动的一个主要阵地。因此,要精心设计科学实验,不断改进实验方式,挖掘实验资源,开拓实验渠道,优化实验过程,创设丰富多彩的学习情境。这样不仅能提高实验教学的有效性,而且有助于学生开展自主探究活动,开阔视野,培养发散思维。作者通过多年的实践与研究,针对初中生的实际,对如何开展科学课实验教学,使学生获得科学知识和技能,激发学生学习兴趣,引发探究的动机和行为,提高实验教学的有效性进行了探索。
Scientific learning should be based on inquiry, and scientific inquiry must be based on scientific experiments. Classroom experiments are one of the main positions for students to carry out inquiry activities. Therefore, we must carefully design scientific experiments, continuous improvement of experimental methods, mining experimental resources, explore experimental channels, optimize the experimental process, create rich and colorful learning situations. This will not only improve the effectiveness of experimental teaching, but also help students carry out self-exploration activities, broaden their horizons and develop divergent thinking. Through years of practice and research, the author tries to find out how to carry out experimental teaching in science class so that students can acquire scientific knowledge and skills, stimulate students’ interest in learning, trigger the motivation and behavior of inquiry, and improve the effectiveness of experimental teaching explore.
