Application of corrosion e-module to improve high-level thinking ability

The media used in learning can be used as an alternative effort to improve the ability of high-level thinking. Therefore, the purpose of this study is to apply corrosion e-module to improve students' high-level thinking ability. The method used is pre-experiment with research subjects as much as 38 students of Chemistry Education second semester. Information is obtained by measuring the improvement of students' high-level thinking ability. The n-gain value in cognitive analyzes is 0.639 with moderate improvement category, the cognitive rate is evaluated at 0.543 with the category of moderate increase and the cognitive level created by 0.73 with the high increase category. Overall n-gain students' high thinking ability is 0.637 with moderate improvement category. This shows the teaching materials in the form of e-module play a role in activating the learning process that impact on learning outcomes. Thus, corrosion learning using e-module can improve students' high-level thinking ability.
