DISlab在教学中应用越来越广泛,这种技术的应用也给我们传统的教学做了有益的补充。一些我们传统教学中的老大难问题,借助DIS传感器有了清楚的认识。文章通过对教学中借助DIS突破了电容器的概念教学进行探究,效果良好,学生认识也更加直观形象。同时,我们不可忽视的问题也随之出现:学生对DIS的原理理解不透彻带来的困惑。因此,在新课程教学中要注重传统实验与DIS系统的优势互补,以期达到更好的教学效果。 DISlab is widely used in teaching. The application of this technology also complements our traditional teaching. Some of the crux of our traditional teaching problems, with the DIS sensor has a clear understanding. The article explores the concept teaching of capacitor breakthrough through DIS in teaching, the effect is good, and the students’ cognition is more intuitive. At the same time, we can not ignore the issue also appears: students understand the imperfect DIS principle of confusion. Therefore, in the new course teaching, we should pay attention to the complementarity between traditional experiment and DIS system in order to achieve better teaching effect.
