Improving the ability of mathematical modeling at the elementary school students through Problem-Based Learning-Based Scaffolding

摘要

The issue of the difficulties experienced by students is not a new thing. One form of student difficulties is the inability of students to solve problems that require a combination of real-life knowledge with mathematical knowledge received at school, namely the transition from the real world to the mathematical model and vice versa, transition model solution to the real world. Through Quasi-Experimental design with pre-posttest design, the researchers apply a problem based learning-based scaffolding in primary school students in Bandung, as an effort to improve students mathematical modeling capabilities. The number of students in the experimental group is as many as 89 students and the control group was 102 students. The results showed that the average value of the gain of the experimental group of 0.36, while the control group of 0,137. Differences in the distribution of both groups gain value, is seen in the medium category and low category. ANOVA test results showed that a large value of F is 222.677, indicates that there is the effect of problem-based learning-based scaffolding to increase the ability of mathematical modeling at the elementary school students.
