Abstract

This study aims to develop a PBL (Problem-Based Learning) based Student Worksheet (LKPD) on the topic of colligative properties of solutions that are valid, reliable, and feasible to be used as an instrument for assessing students’ critical thinking skills. This research employed a Type 1 Design and Development Research (DDR) model consisting of the stages of Analysis, Design, Development, Try-out, and Evaluation, although its implementation was limited to the Try-out stage. The study involved validators comprising university lecturers and chemistry teachers, as well as 106 twelfth-grade science students from MAN 2 Model Medan selected through purposive sampling. Data were collected using semi-structured interview guidelines and assessment questionnaires and subsequently analyzed using the Content Validity Ratio (CVR), Content Validity Index (CVI), item validity tests, reliability analysis, item difficulty index, discrimination index, normality, and homogeneity tests. The findings indicate that out of 16 initial items, 11 essay items were found to be valid (Pearson Corelation > 0,3) and reliable with internal reliability coefficients categorized as good (Cronbach’s Alpha > 0.7). The difficulty indices of the items ranged from difficult to easy, with discrimination indices categorized as moderate to very good. Therefore, the developed PBL-based LKPD is deemed feasible for use in measuring students’ critical thinking skills in the context of colligative properties of solutions.

Abstract

The scientific literacy formative assessment is an instrument designed with the aim of improving students' scientific literacy skills. Based on interviews conducted with the Principal of SMP Negeri 4 Langsa, it is known that the teachers' skills in compiling scientific literacy formative assessment instruments are still low. This is because training regarding formative assessment of scientific literacy has not been evenly distributed among teachers at SMP Negeri 4 Langsa. Therefore, it is necessary to hold training in preparing formative assessments of scientific literacy for teachers at SMP Negeri 4 Langsa. Methods for implementing activities include: 1) planning, 2) implementation, 3) monitoring and evaluation. This community service activity aims to increase the knowledge, understanding and skills of junior high school teachers in Langsa City in developing learning assessments in the form of scientific literacy formative assessments. The results of the PKM activities showed that the pre-test and post-test scores for teachers' scientific literacy formative assessment knowledge increased from an average of 72 to an average of 84. The satisfaction questionnaire also showed that teachers were satisfied with the PKM activities. Apart from that, it was also concluded from the questionnaire that teachers' knowledge and skills related to formative assessment of scientific literacy increased.
