The results of this research obtained the validity of the assessment instrument in the project based learning model with a valid category. The level of practicality of the assessment instrument was categorized as practical by teachers and students. The results of the effectiveness of the knowledge aspect with the results of the pretest and posttest are seen from the classical completeness of each skill which has reached a level of completeness above the minimum expected score. The N-Gain value shows results that meet the high criteria.
