Abstract

The objective of this research was to find out the effectiveness of POE Model on buffer solution material in increasing students elaboration thinking ability. The research method was using quasi experiment with the non equivalent (pretest-posttest) control group design. By using purposive sampling technique, the samples of this research were the second grade science 1 and the second grade science 4 of SMA Negeri 15 Bandar Lampung in academic year 2015/2016. The result of the data showed that the score average n-Gain of experiment class was 0.64 and the control class was 0.28. Based on the average n-Gain of experiment and control class, it can be concluded that POE model was effective in increasing students elaboration thinking ability towards buffer solution material.Penelitian ini bertujuan untuk mendeskripsikan efektivitas model POE dalam meningkatkan kemampuan berpikir elaborasi siswa pada materi larutan penyangga.
