Developing High-Order Mathematical Thinking Competency on High School Students’ Through GeoGebra-Assisted Blended Learning

Abstract

Blended Learning has received considerable attention in the field of mathematics education in recent years. This study combines online learning and face-to-face based learning. Blended Learning is based on some of the weaknesses found in online learning. In Blended Learning, Online learning is not just the learning that collects teaching materials, assignments, exercises, tests, and results of students’ works. It also has to be an interesting and attractive learning so that students’ will have better understanding on learning objectives. One of the tools for developing interesting and attractive online learning process is an open source software called GeoGebra. Blended Learning has very good quality when applied in developing students’ High-Order Mathematical Thinking Competency (HOMTC) as it is evident from previous researches. This study was an experiment based on pretest-posttest control group aiming to examine the influence of Blended Learning and students’ initial mathematical ability on students’ achievement and enhancement of HOMTC consisting of some aspects such as mathematical problem solving, mathematical communication, mathematical reasoning, and mathematical connections. The research subjects are 96 students’ of grade XI IPA 1 SMAN I Gading Rejo in Lampung Province. The results showed that students’ who learned Probability and Statistics under GeoGebra-Assisted Blended Learning (GABL) have higher HOMTC than students’ who received Conventional Learning (CL). There is no differences on students’ HOMTC enhancement between those receiving GABL learning and CL in terms of Initial Mathematical Ability (IMA). HOMTC aspects of the students’ who learned by using BLGA that have the highest enhancement are mathematical connections followed by aspects of mathematical communication, mathematical reasoning and mathematical problem solving..
