随着信息技术的迅速发展和国家新一轮课程改革的推进,以传感器和计算机为基础,实现信息技术与传统实验教学有效整合的数字化实验室应运而生。本文就传感器及其给中学实验带来的变化作一简单论述,期待这一新技术能广泛地应用于中学理科教学,为传统实验教学注入新的活力。 With the rapid development of information technology and the promotion of a new round of curriculum reform in the country, digital laboratories based on sensors and computers to achieve effective integration of information technology and traditional experimental teaching have emerged. This article briefly discusses the sensor and the changes it brings to middle school experiments. We hope that this new technology can be widely applied to the science teaching in middle schools and inject new vitality into traditional experimental teaching.
