演示实验,是学生体验科学探究的重要方法,是学生积累直观经验、提高动手能力、培养科学思维方式和创新意识的有效途径。新课标对高中物理演示实验提出了较高的要求,可是,在现实中无论是演示实验开设的数量,还是演示实验教学的质量都与新课标的要求差距较大,不能达到演示实验教学应有的成效。反思自己十几年来的实验教学,笔者提出以下几点做法,以提高演示实验教学的有效性。一、有效地进行实验演示要提高演示实验的教学效果,首先要有效地进
Demonstration experiment is an important method for students to experience science inquiry, and is an effective way for students to accumulate intuitionistic experience, improve practical ability, cultivate scientific way of thinking and innovative consciousness. However, in reality, no matter the quantity of demonstration experiment or the quality of demonstrative experiment teaching is far from the requirement of new curriculum standard, it can not meet the needs of demonstration experiment teaching Some results. Reflecting on their own experimental teaching more than a decade, the author puts forward the following practices to improve the effectiveness of demonstration experiment teaching. First, the effective demonstration of experiments To improve the teaching of demonstration experiments, we must first effectively
