The method used this study was a three-phase action research cycle. Cycle 1 discovery models by guiding students to discover concepts, the second cycle to find a simple matrix operation process , and the third cycle to find the matrix multiplication operation. This study was conducted in vocational High school Muhammadiyah 2 Bandar Lampung grade10. Data were collected using observation and tests, and the qualitative descriptive analysis was then used to analyze the collected data. Results of this study are: (1) discovery learning model with the syntax of teachers delivering learning objectives, convey a problem, split the group, observed experimental data, reasoning, making conclusions, expressed the work , and teacher evaluate the activities and make conclusions, (2) the activity of learners in the learning is reading a book, listening to the teacher, writing, solving the problems, discussing, and communicating the results, (3) the assessment instrument form a essay test with a validity value of 0.88 (high), a reliability value of 0.99 (high), middle difficulty level of items, and a high acceptable discrimination power of items, and (4) learning outcomes of grade 10 students reached a minimum completeness criteria of 82.53% for cognitive domain, 87.5% for affective domain, and 82.35% for skill domain.
