Abstract

Mathematics problems for elementary school are about the circumference and area of two-dimensional figures. Students only memorize the formula without understanding the meaning of the rim and area. The objective of this research is to examine the effectivity of the CTL approach with Geoboard on mathematics learning. The research population was 126 four graders of public elementary schools in Tamansari Kebumen School Group. One experimental class and one control class were selected. Both of the studies were given a pre and post-test. The data consisted of learning outcomes that were analyzed using a z-test and t-test, as well as student activities that were analyzed using descriptive statistics. The research results showed that: 1) the mastery learning of the experimental class reached 75%; 2) the experimental class average of learning outcome was higher than the control class; 3) the increase of learning outcomes were classified as 'medium'; and 4) the student activities in solving problems enhanced from 88.34% to 96.66%. The research concluded that the CTL approach with geoboard media is sufficient to be applied in mathematics learning for the four-grade students of public elementary schools in Tamansari Kebumen School Group.
