Comparison of guided discovery assisted by calculators and scientific approaches in terms of students' higher-order thinking skills in mathematics

Abstract

This study aims to describe: (1) the effectiveness of calculator-assisted guided discovery learning in terms of Higher Order Thinking Skills (HOTS) in mathematics, (2) the effectiveness of learning the scientific approach learning in terms of Higher Order Thinking Skills (HOTS) in mathematics, (3) find out which one is more effective between calculator-assisted guided discovery learning and scientific approach learning in terms of students Higher Order Thinking Skills (HOTS) in mathematics.This study was a quasi-experimental research with the nonequivalent pretest-posttest group desain. The study population included all students of grade X classes from 6 existing Mathematics and Natural Sciences group classes in SMA Negeri 1 Karawang and the sample was class X MIPA 3 as experiment group and class X MIPA 5 as control group which were randomly selected. Calculator-assisted guided discovery learning was conducted in experiment group and scientific approach learning was conducted in control group. The research instruments were mathematics HOTS test and observation sheet of learning implementation. Data were analyzed by one sample t-test and independent sample t-test with significance value of 5%. The results of this study showed that: (1) calculator-assisted discovery learning is effective in terms of Higher Order Thinking Skills (HOTS) in mathematics, (2) scientific approach learning is effective in terms of Higher Order Thinking Skills (HOTS) in mathematics, (3) calculator-assisted guided discovery learning as effective as scientific approach learning in terms of Higher Order Thinking Skills (HOTS) in mathematics.
