ABSTRACT

The aimed of this research is to describe the effectiveness of scientific approach on acid base topics to improve planning skills. The population in this research was 166 students from all the IPA of the 11th grade in SMAN 1 Pringsewu for 2014/2015 academic year. This quasi experiment used non equivalent (pretest-posttest) control group design, with the IPA1 and the IPA2 of the 11th grade as the research class, where they were obtained by using purposive sampling. The result shows that the average of planning skill in experimental and control class were 0.47 and 0.34, respectively. The purpose of this study is to describe the effectiveness of a scientific approach to acid-base material in improving the planning skill. The population of the study were 166 students from all grade XI IPA SMAN 1 Pringsewu academic year 2014/2015. The quasi-experimental method uses non-equivalent (pretest-posttest) control group design, with class XI IPA1 and XI IPA2 as research class, where the research class is obtained by using purposive sampling technique. The results showed that the average n-Gain skill planning in the experimental class and control classes were 0.47 and 0.34, respectively. Based on the results of hypothesis testing, it is concluded that learning with a scientific approach on acid-base material is effective in improving planning skills. Keywords: Â acid basa, skill planning, scientific approach
