The Development of Mathematical Problem Solving Ability by Using 4Ex2 Instructional Model and Model Method for Sixth Grade Students

Abstract

          The purpose of the research were to 1) To compare mathematical problem solving ability before and after learning by 4Ex2 Instructional Model and Model Method and 2) Learning about Grade 6 Students Estimate on learning management by 4Ex2 Instructional Model and Model Method. The sample in this research consisted of 31 Grade 6 students class 1. The simple random sampling technique was employed for selecting, the sample group and classroom was a random unit. In addition, the research tools were; 1) eight learning plans by 4Ex2 Instructional Model and Model Method  2) a pre and post-test of mathematical problem solving ability and 3) a questionnaire survey of student’s opinions toward Learning by 4Ex2 Instructional Model and Model Method.    The mean ( ), standard deviation (S.D.) and dependent t-test were applied for data analysis.
