Assessing high school student’s chemical literacy on salt hydrolysis

Abstract

Each instruction requires appropriate strategies and assessments, including instruction of chemical literacy. The subject matter of salt hydrolysis, which is closely related to daily life, is suitable for the instruction of chemical literacy. The purpose of this research was to produce a valid and reliable chemical literacy test (CLT) on salt hydrolysis to assess high school students’ chemical literacy. This study applied the design of research and development and also surveyed. The test development was carried out through five stages, namely (1) literature review, (2) item development, (3) expert judgment, (4) pilot study, and (5) finalization. The survey was carried out integrated with the pilot study phase of the test development stage. The data of the pilot study collected by a valid and reliable test produced in the development stage was analyzed as survey data. The research and development produced a chemical literacy test consists of 24 accurate items with Cronbach’s Alpha reliability coefficient of 0.605. Analysis of student performance using valid and reliable tests shown that the respondents’ average chemical literacy score was 39.69 from a maximum score of 100. This score belongs to the upper low or lowers moderate category.
