The Chemistry Competency Achievement of SMA Negeri 7 Palu Students Using Predict, Observe, and Explain (POE) Learning Model

Abstract

This study is aimed to derive a description of learning result improvement on salt hydrolysis material by implementing POE (Predict, Observe, Explain) learning model on the students of grade XI at SMA Negeri 7 Palu. This study was a pre-experimental within Static Group Comparison design. Sampling was carried out in a simple random with class XI MIA 1 as the experiment class and XI MIA 5 as the replication class. The instruments used in this study divided into 3 competencies, the affective competency using an observation sheet, the psychomotor competency using self-assessment questionnaire and the cognitive competency using a final test. Statistical inferential analysis using t-test one right side by requiring normal and homogeneous data. The average psychmotor competency of students in the XI MIA 1 is 81, whilst for replication class is 79. The average cognitive competency of students in XI MIA 1 is 77 with deviation standard of 10.55, whilst for replication class is 75 with standard deviation of 12.98. The result of hypothesis test using t-test one right side is tcalculated ttable or 3.32 1.71, whilst for replication class is 1.851.72, so H0 was rejected. This result concludes that the implementation of POE learning model in Grade XI students at SMA Negeri 7 Palu improves learning achievement on salt hydrolysis material to be more than competency minimum standard of 70.
