初三物理教学中,每当进行到热学的演示实验时,教师最伤脑筋的是学生看不到温度计的读数,直观性差,即使是第一排学生也无法看清,只好任凭教师读数,说服力不强,影响了教学效果,使重难点知识理解不深。为了解决这个难题,我们试制了两支电子温度计,用它可以将温度的变化值通过电子线路反映到电流表
In the physics teaching of the third grade, whenever the demonstration experiment was conducted in the thermal sciences, the most troublesome thing for the teachers was that the students couldn’t see the thermometer’s reading. The intuitiveness was poor. Even the students in the first row could not see clearly and had to leave the teacher to read and persuade. The strength is not strong, affecting the teaching effect, so that the knowledge of difficult points is not deep. In order to solve this problem, we tried two electronic thermometers, which can be used to reflect the temperature changes through the electronic circuit to the ammeter
