在苏教版高中化学选修4“原电池”一节中,教材介绍了盐桥,大多数学生无法理解其作用。笔者在教学中,以教材内容为基础,利用中学数字化实验技术,与学生一起探究盐桥在原电池中的应用。数字化实验是一种新型的实验技术,在新课程理念的指导下,可帮助教师和学生实时、快速、准确地设计和实施中学化学中的部分实验,开展定量的科学探究。该技术的实验器材主要包括:数据采集器、应用软件及各类传感器、计算机等。
In the Sujiao version of high school chemistry elective 4 “original battery ” section, textbooks introduced Salt Bridge, most students can not understand its role. The author in teaching, based on the content of teaching materials, the use of high school digital experiment technology, and students to explore Salt Bridge in the original battery applications. Under the guidance of the new curriculum concept, digital experiment can help teachers and students to design and implement some experiments in middle school chemistry in real time, quickly and accurately, and carry out quantitative scientific inquiry. The experimental equipment technology include: data acquisition, application software and various types of sensors, computers and so on.
