Main Article Content
Objectives of this research were to analyze the mathematical competencies of students with the mathematics competency exam level 6 of 30 items. Methodology was a multi-phase research (Multi-phase Design) was divided into two phases: phase 1, quantitative and qualitative researches with students taking the test. Then, the test results were analyzed in depth (In-depth Analysis) to find the competency. Phase 2, a qualitative research., by analyzing the answers to identify issues in the development of teaching and learning management A tool used was the test that can measure the mathematical competency. The target group was 139 students aged 12-15 years. The data were analyzed tool from answer papers.
The results showed that 58.51% of the target group had competencies in the first category of competencies related to knowledge. They could apply the math knowledge and skills that arose from classroom teaching. And calculation skills discussion skills, measurement skills, data management and statistics skills, could be applied in problem solving in real-world situations. In addition, 40.63% of the target group had competencies in the second side of competencies related to application. They realized and applied tools and skills. Mathematics could be used in situations and solve problems in daily life by recalling their competencies to apply knowledge and skills in daily life and apply competency to solve problems from unplanned situation. They could apply evaluating and developing processes and results in solving situations and problems in daily life.
