The Development of a Measurement Instrument to Assess Student’s Competence in Connecting the Multiple Representations in Chemistry on Acid-Base Titration

The purpose of this research was to develop a measurement instrument to assess student’s competence in connecting multiple representations in chemistry, specifically focusing on acid-base titration topics. The student’s competency was categorized into three levels, ranging from Level 1, where students demonstrate a correct understanding of the concept of acid-base titration at the macroscopic, submicroscopic,
