This study is aimed at evaluating the feasibility of instructional media which is a determinant of the learning quality, particularly in the field of vocational technology. The study was carried out at Vocational School of Technology of North Sumatra Province involving 218 teachers as respondents in three groups namely BS, CS, and ES. Media feasibility analysis refers to the criteria of Alessi and Trollip. The results of the study indicate that SB teachers used the most media in comparison with SC teachers and SE teachers, and the most widely used form of visual media compared to video, media miniatures and animation. The overall media usage only fulfilled 46% of ideal requirements, and the animation medium was considered to be the least adequate miniature media, video and visual media. From the feasibility aspect, supplementary information is the lowest compared to other aspects while the pedagogy aspect is the highest. The overall average media feasibility is low. The findings of this study reinforces the results of previous studies that lack of instructional media leads to lower learning outcomes. The study recommends greater attention to develop instructional media as needed, especially animation for the effective learning process and the improvement of education.
