The main objectives of the thesis were to develop a Computer Assisted Instruction (CAI) lesson for Squirrel cage Induction Motors in Electrical Machine subject and to study the effective of the CAI lesson. There were two key devices for product development : the CAI lesson and the tests. The devices were thoroughly inspected by the experienced experts. After the devices had been implemented with the samples, the findings were as the following : 1. A seven-unit CAI lesson was developed systematically. 2. The means of the samples testing scores from seven units was 84.97% and 80.95% for the whole CAI lesson. This indecated that the obtained scores had met the previously defined standard. 3. The samples gained scores showed the level of significance at 0.01. Due to the findings, the CAI lesson effectively enhanced the samples achievement. |
