Profile of student's conception in implementation of predict-observe-explain (POE) strategy on thermochemistry concept

Abstract

Every student has different understanding of a concept. To achieve expected cognitive abilities, so it needs a good understanding of concept. Based on preliminary research understanding of thermochemistry concept is low. This low ability caused of majority of student still have misconception. This misconception should be removed, one of the way to remove is using predict-observe-explain (POE) strategy. The aim of this research is to find out profile of student conception after implementation of POE strategy. The subject was 36 student of science class at 11th grade of SMA Kemala Bhayangkari 3 Porong. This research was using three tier diagnostic test to know student's conception. Generally the result was student's conception changed. It indicated with the result of pre-test, initially 72.80% student have misconception, 15.14% didn't know the concept and 12.78% knew the concept, while the result of post-test changed become 92.78% knew the concept, 3.06% didn't know the concept and left 4.17% with misconception. So it can be concluded that student's conception profile after implementation POE strategy generally changes become knew the concept and student conception who didn't know the concept and misconceptions showed low percentage.
