Vol. 5 No. 1 (2025): March - ON PROGRESS

This research was conducted because students felt that the existing teaching materials were boring, less interesting, and less able to make students understand the material easily. Teaching materials that can make it easier for students to understand the material are teaching materials that are made by themselves between students and lecturers, so that they do not only buy books at publishers, but students can be directly involved in writing the material. The computer application teaching materials themselves have never been made by lecturers before. So it is necessary to develop teaching materials in computer application courses so that students can more easily and understand the material. The purpose of this study is to describe the procedure for developing teaching materials, producing appropriate teaching materials, and describing the effectiveness of developing teaching materials. The type of research is Research & Development (R & D). The results of the research that has been conducted, it is known that the computer application teaching materials have been validated by media expert lecturers and learning material experts. Based on the validation results from media experts, an average of 36.00 was obtained, which is included in the "Good" criteria with an ideal percentage of 90%. Meanwhile, the validation results from material experts obtained an average of 47.50 which is included in the "Very Good" criteria with an ideal percentage of 79%. The trial stage was carried out twice, namely a limited trial and a broad trial. From the limited trial, the weaknesses and strengths of the computer application teaching materials created were known, so the researcher made a second revision after conducting a limited trial. In the 2nd trial, namely a broad trial, several results were obtained to see whether the computer application teaching materials were effective or not. The hope of developing this teaching material can produce quality teaching materials as a source of learning for students in receiving lecture materials.
