Validity and Reliability of Assessment Instruments for Analytical Thinking Ability and Chemical Literacy in the Colligative Properties

Abstract

This study aimed to develop and determine the construct validity, reliability, and items analysis of the instruments for assessing analytical thinking abilities and chemical literacy in the colligative properties materials. This study was a research and development (R&D) utilizing the ADDIE model. The subjects of this study were 30 students of class XII at senior high school (SMA) in Bengkalis. The results revealed that of the 15 items on the analytical thinking skills and chemical literacy, 10 items had good construct validity and had very high reliability test values, with the Cronbach alpha of 0.887. The results of item analysis of the instrument which was developed for assessing the analytical thinking skills and chemical literacy showed that for the difficulty indices, 80% of the items were classified as moderate items and 20% of them were classified as easy items. Then, the analysis results for the discrimination indices revealed that 80% of the items were good while 20% of the items were categorized as satisfactory. In addition, based on the analysis of construct validity, reliability, and items analysis, the assessment instrument for analytical thinking ability and chemical literacy was valid and feasible to be used to measure the students’ analytical thinking skills and chemical literacy on the material of colligative properties on a broad scale test.

Construction of Analytical Thinking Skills Instruments for Micro Teaching Courses

“…Other research that specifically addresses the development of analytical thinking instruments is still limited to elementary school students (Blegur, Rajagukguk, et al, 2023;Kesorn et al, 2020; Agus Mahendra / Construction of Analytical Thinking Skills Instruments for Micro Teaching Courses Thaneerananon et al, 2016) and high school students (Wiyarsi et al, 2019;Ad'hiya & Laksono, 2020;(Yandriani & Erna, 2020). It is only verified that the research that has succeeded in developing analytical thinking skills instruments using a sample of university students.…”

“…According to, students must have analytical thinking skills to complete research and develop new knowledge and innovations. Given that analytical thinking skills are important for the development of student competence students (Jumhur et al, 2021;Sari, W. K., & Nada, 2022;Supriati, Y. et al, 2021), the need for instruments by adopting "global" ideas and being reduced according to "local" contexts and courses is needed to operationalize learning activities according to problem-solving as well as being a valid and valid parameter in measuring analytical thinking student (Ad'hiya, E., & Laksono, 2020;Wiyarsi et al, 2019;Yandriani & Erna, 2020).…”
