THE QUALITY IMPROVEMENT OF MATHEMATICS LEARNING USING PBL MODEL BASED ON WEB

Abstract

The main objective of this research is to describe the development of the mathematics learning using problem based learning (PBL) for Junior high school olympiad preparation. The approach used in this research is the development of the implementation through Classroom Action Research (CAR). Development of the device uses the development model of 4-D (Four D model) from Thiagarajan. In this research is found a learning device using PBL model based on web for Junior high school olympiad preparation that it is valid, practical, and effective. The device was developed learning syllabus, lesson plans, teaching materials, students worksheets, and study achievement test. The test device and dissemination limited classes use research subjects 8th grade students of SMP Negeri 1 Magelang, Central-Java, Indonesia. The results of the implementation of the learning development through CAR show that the device is effective , which is characterized by (a) the ability to problem solving, (b) problem-solving ability is affected by the activity of students where problem-solving ability is affected by the students' process skills and problem solving ability test affected both of activity and process skills of students, and (c) the problem solving average ability increases every cycle. The results of the development of this learning can be disseminated more widely.
