Abstract

This study used descriptive research and pre-experimental design. The first one was used to identify student misconception in the mass balance topic at macroscopic, sub-microscopic and symbolic levels. The second design aims to correct the misconceptions discovered by using the POE strategy. After three weeks the delayed test was done to find out the concept improvement using POE strategy. This design was also used to determine the effectiveness of POE strategies to achieve the aims. The results showed misconception on mass balance material with an average of 32.97%. The average POE effectiveness of 76.02% with high effectiveness criteria and retention of understanding with POE strategy after 2 weeks on average was 91.27% with very good criteria.
