Developing Learning Materials Based on Problem-Based Learning to Improving Students Mathematical Problem Solving Ability and Self-Regulated Learning at MAN Hutagodang Labuhanbatu Selatan

Abstract

There were three objectives of this research, namely; (1) to describe the validity of learning devices based on problem-based learning model to improve the ability of mathematical problem solving and students’ self-regulated learning; 2) to describe the practicality of learning devices based on problem-based learning model to improve the ability of mathematical problem solving and students’ self-regulated learning; 3) to describe the effectiveness of learning devices based on problem-based learning model to improve the ability of mathematical problem solving and students’ self-regulated learning; and 4) improvement of mathematical problem solving ability and self regulated learning of students taught through problem-based learning based device. This research is a development research. This research was conducted through two stages, the first stage, the development of learning devices based on problem-based learning using Four-D development model, and the second phase tested the of learning devices based on problem-based learning developed in the XI IPA-1 and XI IPA-2 MAN Hutagodang Labuhanbatu Selatan class. From the results of experiment I and experiment  II obtained: 1) problem-based learning developed valid; 2) problem-based learning developed practically; 3) problem-based learning  that are developed effectively, in terms of a) students' learning mastery in experiment I test of 71.43% and 92% in experiment II; b) the achievement of teachers' ability to manage the learning on experiment I of 2.83 (good enough) and experiment II of 3.37 (good); 4) improvement of students' mathematical problem solving ability increased from t experiment I with an average of 76.91 to 8.15 in experiment II; and 5) increased student self-regulated learning increased from experiment I with an average of 2.97 to 3.03 in experiment II.
