Retracted: Difference Effect of the Open Ended Approach and Realistic Approach on the Ability of Problem Solving Student Elementary School

Abstract

The study was conducted on the fourth grade students at SD Negeri 1 Blang Mangat. This research type Pre-Experimental Design. Data analysis using t-test and gain-assisted score test. The results show that: (1) the influence of realistic approach is better than the open-ended approach to problem solving ability. It is based on tcount (= 2.167) > ttable (= 1.673); and (2) improved student problem solving skills taught with a higher realistic approach than students taught by open-ended pendants. This is based on the calculation of gain score and the characteristics of both models. Realistic approach has characteristic that is using LAS which contains real problem and human activity, whereas open-ended approach have characteristic that is using open matter with various settlement.
