The Result of Misconceptions Survey in Biology Regarding the Chemical in Organism with a Two – Tier Diagnostic Test for Tenth Grade Students

Abstract

       The goal of biology learning is to provide students with scientific knowledge, understanding of principles, theories, boundaries, and limitations. It is believed that students can comprehend concepts on their own by combining existing knowledge and understanding within daily life. But concept understanding may not be complete or partially correct. The two – tier diagnostic test in biology regarding the topic of chemical in organism was used to survey students’ misconceptions. Sixty-three tenth graders were purposively selected from the science and mathematics classes in the first semester of the academic year 2022, school in Surat Thani province.
       The result showed that in the item 3 about the types of carbohydrate, students had the most misconception at 79.37%. The second one was at 66.67% which was about the factors and inhibitors of enzyme. Moreover, the least misconceptions accounted for 36.51% about the carbohydrate test. The results are important data used to design effective learning management to achieve biology curriculum goals and develop concept understanding.
