The practicality of mathematics learning module on triangles using GeoGebra

Abstract

Abstract The 2013 curriculum in Indonesia requires students to be able to develop knowledge independently, creatively and skillfully in solving mathematics problems. One way that can be taken by professional mathematics teachers to support the curriculum is to develop precise learning modules that integrate software dynamically and open source, such as GeoGebra. This study aims to determine the practicality of the module developed in mathematics teaching and learning on triangles using GeoGebra. The study used the Plomp development model, which consists of three phases, namely preliminary research, prototyping phase, and assessment phase. The test trial was conducted four times on students of class VII SMP Negeri1 Idi Rayeuk, Aceh. The results showed that the mathematics teaching and learning module using GeoGebra software fulfilled valid and practical criteria. The validity of the module is obtained based on the results of validation by five validators. Meanwhile, the practicality of the module is achieved based on the recommendations of five validators stated that the module could be used with a minor revision and the level of implementation of learning using the module is good. For future research, it is crucial to apply this study on a broader scale to determine the effectiveness of the module.
