Development of Discovery Learning-Based Digital Teaching Materials for Network Service Technology Subjects at Vocational Schools in Turen Malang

Abstract

The subject of Network Service Technology (NST) is a subject in the Computer and Network Engineering class XI expertise program. This subject is a new subject in the Revised 2013 Curriculum. Based on interviews and observations conducted with NST subject teachers and class XI Computer and Network Engineering students, it was found that it was necessary to develop teaching materials to support the learning process in these subjects because these subjects were relatively new and there were still few teaching materials and learning media available. The teaching materials developed are interactive digital teaching materials with the epub extension and can be accessed with Android, Windows, and iOS operating systems. The development model used is the Sadiman model development method. After the teaching materials have been developed, the teaching materials are validated by learning multimedia experts. Then a trial of teaching materials was carried out to students. The trials conducted on digital teaching materials were divided into three stages, namely one-on-one trials, small group trials, and large group trials. The average result obtained from material expert validation is 94.75 percent. The result of media expert validation is 87.5 percent. The average results of one-on-one, small-group and large-group trials conducted on students were 87.5 percent. From the three results obtained from material experts, media experts and students, it can be concluded that the teaching materials developed can be declared very valid and feasible to use because they get an average score percentage of above 80 percent.
