The Development of Learning Achievement in Topic of Solving Polynomial Fractional of Ninth Grade Students by using Problem-Based Learning Approach

Abstract

The purposes of this research were to: 1) compare the student’s achievement before and after learning polynomial fractions by using problem base learning. 2) compare the progress teaming in a group of students before and after learning polynomial fractions by using problem base learning. 3) study the student’s retention of learning. The samples were consisted of ninth grade student of Mahachanachaiwittayakom school, Yasothon province simple random sampling was selected. The researcher selected a sample consisting of ninth grade students. The instruments used for this experiment were learning management plan, achievement test as a pre-test and post-test and a test on retention. The research results were as follows: 1. The students’ achievement gained after learning polynomial fractions by using the problem base learning (PBL) was found significantly higher than the scores gained before at the level of .05 2. The progress of learning in a group of excellent students was found the more progress learning than a mild group of students and a moderate group gets the lowest score respectively. 3. The student’s retention of learning polynomial fractions using problem base learning (PBL) and the tradition method examined 2 weeks after learning fractions polynomial by using the problem base learning was found significantly not difference the scores gained before at the level of .05
