Abstract

Improving media in learning process could be used as an alternative attempt to improve high-order thinking skills. In this research, we have succeeded in applying e-module of corrosion in order to improve students high-order thinking skills. The research used pre-experiment method with one-group pretest and posttest research designs. The research used one class experiment without a comparison class. The research subject was 38 students of second semester Chemistry Education. Categories of each students high-order thinking skill improvement were determined using n-gain formula. The n-gain value of students analysis skill is 0.639, categorized as a medium improvement. The n-gain value of students evaluation skill is 0.543, categorized as a medium improvement. And, the n-gain value of students synthesis skill is 0.73, categorized as a high improvement. The overall n-gain value of high-order thinking skill is 0.637, which is categorized as a medium improvement. The result showed that e-module contributed to activate a learning process that resulted improvements of high-order thinking skills.

Keywords: high-order thinking, e-module, corrosion, analyze, evaluate, create.
