The purpose of this study was to determine the influence of learning resources of engineering mechanics modules on student learning outcomes in mechanics subjects in vocational high school (VHS) 1 Sedayu. This study used an experimental method with a nonequivalent control group design. Experimental research designs used are pre-experimental designs, true experimental designs, factorial experimental designs, and quasi-experimental designs. The sample used was class X TP A as a control group and X TP C as an experimental group. The results of this study indicate that there is a significant increase in achievement in the experimental group students after using improved learning media.
