Analysis of Chemistry Problem-Solving Ability in Symbolic Level for Senior High School Students

Abstract

Analysis of Chemistry Problem-Solving Ability in Symbolic Level for Senior High School Students. Objective: The study aims to analyze the ability to solve symbolic level of chemistry problems on buffer solution. Methods: This research used descriptive qualitative method. Population in this study was used as research sample, i.e sixty students from XI MIPA. Data collection was carried out using a three-tier multiple choice diagnostic test and a student response questionnaire. Findings:The results showed that the ability to solve symbolic level chemistry problems on buffer solution was still low, with an average percentage of understanding the concept was 9.77%, misconceptions was 57.75%, and not understanding the concept was 32.48%. Students' responses to the use of three-tier multiple-choice questions were positive, with a percentage of 74.30%; students gave good responses to the three-tier test, so this test is categorized as good to identify the level of student understanding in solving symbolic level chemistry problems on buffer solution. Concusion: The research findings confirmed that the diagnostic three-tier test is a good diagnostic test to analysis chemistry problemsolving skills.
