Abstrak

This study aims to improve the ability to solve mathematical problems XII grade students in IPS 1 SMA 1 Gedeg through problem-based learning. The increased of ability to solve mathematical problems can be seen from the learning process and the results of the test's ability to solve problems in every cycle.

Besides the purpose of learning mathematics not only on cognitive aspect but also on affective aspect in this case the students' attitudes toward mathematics itself. in which case, this is called a mathematical disposition.

This research is a classroom action research in XII IPS 1 SMA 1 Gedeg in the academic year 2018/2019. This actions carried out in three cycles, each cycle consisting of two meetings. At the end of each cycle, students were given a problem-solving skills tests. The instrument used to collect data in this study a lesson observation sheets, problem solving ability test that have consulted with professors, mathematical disposition questionnaire, and interviews.

The results showed an increase in students' ability to solve mathematical problems through the application of problem-based learning.

Based on observation, problem-based learning activities carried 55.90% in cycle 1 and 68.89% in cycle 2 and 78.96%. With the application of problem-based learning, math problem-solving skills of students increased by 18.40% from the average value obtained in cycle 1 60.00 into 72.00 in cycle 2 and cycle 3 at 78.40. Likewise, every indicator has increased. The results of questionnaire analysis mathematical disposition obtained in cycles of 1.2 and 3 is the average value respectively 62.84%, 64.32%, and 66.32%. The increase also occurred in the number of students who obtain a mathematical disposition in the excellent category in cycle 2 was obtained two students and as many as three students in cycle3. The result shows that the problem-based learning mathematical impact on the disposition of learners.
