Development of Learning Material Based on Problem Based Learning to Increase Mathematical Connection Ability and Self-Esteem Students of SMP Negeri 1 Panai Tengah

摘要

This research aim to analysis: (1) the increasing of students’ mathematical connection ability by using learning material based on problem based learning that has been developed, (2) the increasing of students’ self-esteem by using learning material based on problem based learning that has been developed, (3) the quality of learning material developed based on problem based learning and (4) the students’ mistake in completing the mathematical connection ability test on the comparison material. The development of learning based on problem based learning by using the 4-D development model. The stage of this research includes define, design, develop, and disseminate. The subjects of this research were students of class VII -1 and VII -2 SMP Negeri 1 Panai Tengah. From the results of trial I and trial II were obtained: (1) there was an increase in students’ mathematical connection ability on posttest trials I and trials II of 5 point, (2) there was an increase in students’ self esteem on posttest trials I and trials II of 0,10 point, (3) according to the expert, the validity of learning material is valid, the practicality of the learning material has fulfilled the practical criteria that have reviewed from: a) the validator stated the learning materials can be used with a little revisions; b) the result of observation of learning material has been done as said good, and the effectiveness of learning material has fulfilled the effective criteria in terms of: a) the mastery of students learning in classical; b) limits of tolerance that have been established on students’ active activity; c) students’ responses is positive to the components of learning materials and learning activities, and (4) the type of error that is often done by students in completing a mathematical connection ability test were mathematical error aspects of the transformation of 33,33%.
