The aim of the research is to determine the effectiveness of an electronic program based on interactive multimedia in developing the skills of producing lessons, an electronic course in equipment and machinery for the third grade of secondary industry, specializing in ready-made clothes. The research sample included (30) male and female teachers of scientific disciplines at the Technical School for Girls 2 in Zagazig. The research tools consisted of an achievement test, a note card, and a product evaluation card, and after ensuring the validity of those tools for the application, they were applied to the research sample before and after, statistical treatment of the data was carried out and hypotheses were tested, and the results resulted in the presence of statistically significant differences at the level of 0.01 between the mean scores of the experimental sample in the pre and post application in favor of the post application. There are statistically significant differences at the level of 0.01 between the mean scores of the experimental sample in the pre and post application of the observation card of the performance side of the skills of designing and producing computerized lessons in favor of the post application, which indicates the effectiveness of the training program based on interactive multimedia in developing the skills of designing and producing computerized lessons for teachers of industrial secondary schools.
