摘　　要：由于电导测定一课内容枯燥,难以理解,为了提高教学质量,加强课堂演示.设计制做了电导测定示教板通过实验数据验证其误差范围在-3.3％～2.6％之间,此教具能够把课堂演示和教学有机地结合在一起。The contents of conductance measurement is so dull that it is difficult for students to under-stand. The teach board is made to improve the teaching quality and its error range is between3. 3% and 2. 6%. This teaching aid combines the teaching and class demonstrationeffectivelly.
