This study aims to determine the effect of the Learning By Doing model on the reasoning abilities of students in class X SMKS-PP Putra Jaya Jabal Rahmah Stabat, Langkat Regency. This research is a type of quasi-experimental research (quasi-experimental) with a nonequivalent control group design. The population in this study were all students of class X SMKS-PP Putra Jaya Jabal Rahmah with the determination of the sample through random sampling technique (random sampling).
