如何在实验课中适时、适当介入多媒体技术,提高实验教学的有效性?我们需要借助具体的课例加以澄清与研究。《温度与温度计》就是我们青浦区小学自然学科探索“少教多学、鼓励挑战性学习”的一个研究课例。我所关注的正是多媒体在实验课中的作用与如何有效介入这一主题。《温度和温度计》是牛津自然第四册第五单元的内容,这个单元通过向学生介绍热气球的工作原理,引导学生从物体的冷热、温度的变化等方面开展各项活动。在活动的过程中学会用科学的方法检测水的温度,了解生
How to timely and properly intervene in multimedia technology in the experimental class to improve the effectiveness of experimental teaching? We need to clarify and research with specific lessons. “Temperature and Thermometer” is our primary school of Qingpu District, a natural science exploration “to teach less, encourage more challenging learning,” a research case. What I’m concerned about is the role of multimedia in experimental lessons and how to effectively get involved with this topic. The “Thermometer and Thermometer” is the fifth volume of Oxford Natural Volume IV, which introduces students to the working principle of a hot air balloon and guides them to perform various activities such as hot and cold objects and changes in temperature. In the process of activities learned to use scientific methods to detect water temperature, understand the students
