ABSTRACT This study aims to enhance students’ concept mastery through implementation of Argument-Driven Inquiry (ADI) on salt solutions learning. Method of this research was quasi-experiment, with pretestposttest nonequivalent control group design. The subjects were 39 students in experimental class and 41 students in control class at one of high school at Majalengka city, West Java. Instruments in this study consisted of 18 items multiple choice test. The subject involves 5 subconcepts (i.e. salt solution, neutral solutions, acidic solutions, basic solutions, and hydrolysis constant). The results shows that salt solution learning using ADI have been enhance concept mastery in middle category N-gain (67,4%). Based on N-gain result for each subconcept, showed that subconcept of acidic solutionsand basic solutionsthere were in high category, and neutral solutionsthere was in low category mastery
Key Words: Students’concept mastery, ADI, Salt solution learning .
