Abstract
Curriculum changes are common in educational institutions, including in polytechnics. One of them is textile polytechnic. This change in curriculum certainly has an impact on changes in the order of courses, syllabus preparation, learning models, and others. One of the affected subjects is the practicum refinement process, where the regular curriculum (regular class) is in the third semester, and the dual system curriculum (dual system class) in the second semester. This practicum is expected to be able to equip students with knowledge about improvement technology so that students are able to have the skills to carry out operations in the preparation process for improvement. The research subjects were 36 students (18 regular class students and 18 dual system class students) textile program of chemistry major in one of the polytechnics in Bandung. Instruments used in the form of observation, questionnaires, interviews, and means score. From the statistical calculations it can be concluded that there is a relationship between the experimental activities and students^ understanding of concepts and there are significant differences in understanding of concepts between the regular class and the dual system class after the application of the experimental design is carried out.
