Abstract

The quasi experimental research which use non equivalent pretest-posstest control group design was conducted on the 11th grade of IPA5 and IPA6 of SMAN 1 Natar for 2014/2015 academic year. The aim of this research was to describe the effectiveness of Problem Solving learning model to improve classification and inference skills on acid-base topic. The results showed that the mean of n-Gain of classification skill in experiment and control classes were 0.46 and 0.31, respectively, and the mean of n-Gain of inference skill in experiment and control classes were 0.44 and 0.32, respectively. Based on it, statistically the mean of n-Gain on classification and inference skills in experiment and control classes were different signifation. It can be inferred that problem Solving learning model was effective to improve classification and inference skills on acid-base topic.Penelitian kuasi eksperimen dengan desain non equivalent pretest-postest control group design telah dilaksanakan di kelas XI IPA5 dan XI IPA6 SMAN 1 Natar Tahun Akademik 2014/2015.
