TY - JOUR A1 - Wahyu Isti, Nugroho IS - 2 N2 - Abstract This study aims at knowing efectivity of job sheet developed for machining practice. This study was a quasi-experimental with non-equivalent control group design. The samples were XI MA class as a control group and XI MB class as an experimental group. The data were collected using pretest-posttest results and then analyzed using t-test. The experiment result shows that mean score of control group raise up from 69,16 to 80,08. T-test result indicate that implementation of job sheet developed was statistically effective.
