أثر إستخدام تقنیات الحاسوب في زیادة معلومات الطلبة في إجراء تجربة السیطرة على سرعة محرك تیار مستمر عن طریق الفیض المغناطیسي

Abstract

The aim of this research is to study the effect of using computer techniques to increase students information at the experimenting the speed control of dc motor by the magnetic field. Simulation of the experiment has been used by implementing “Electronics Workbench” software. The random sample, included (30) second year electrical department students, divided into two groups , experimental and control with pre-test and post-test . The results showed great advantages for the experimental group through the use of computer program in the laboratory. The calculated (t) was (10.6) which was significant and showed statistical differences between the experimental and control group. According to the results, using the simulation in electrical machines laboratory experiments through “Electronics work bench ", had been enforce the students learning. The researchers recommended to utilize this techniques either as supporting program to the ordinary laboratory work or as self- learning method which provide the possibility to repeat the experiment or / and validate its results.
