Development of Mathematics Module Based on Metacognitive Strategy in Improving Students' Mathematical Problem Solving Ability at High School

摘要

This research is based on problems that occur in SMA Negeri 3 Gunungsitoli, that is mathematical problem solving ability of student is still low. Based on the results of observations by researchers, it is because the teaching materials used by students less attention to students, not equipped with tests of mathematical problem solving ability or still contains routine questions. This encourages researchers to develop teaching materials in the form of mathematics modules based on metacognitive strategies equipped with tests to measure mathematical problem solving ability of students. The development of this math module uses the Dick & Carey development model. The criteria of validity and effectiveness are used by the researcher to determine a good mathematics module. Module validation by three experts and two practitioners earned an average total validity score of 4.58 with valid criteria. Mathematics module based on metacognitive strategy in improving students’ mathematical problem solving ability of SMA Negeri 3 Gunungsitoli developed is effective. In trial I obtained the results of the test of mathematical problem solving ability with an average value of 2.99 and on trial II obtained the test results of mathematical problem solving ability with an average value of 3.18. Based on the result of mathematical problem solving test in trial I and trial II it was found that there was an improvement of students' mathematical problem solving ability.
