Abstract

This study aims to analyze the increase in students' scientific literacy by implementation of case method learning. This is a quasi-experimental research using a one group pretest-posttest design. The research sample is the first semester students of the Chemistry Education Department at Universitas Samudra in the odd semester of the 2022/2023 academic year. This research consists of four stages, namely material analysis, development of tools and instruments, implementation, and data analysis. The scientific literacy test instrument was used to measure students' scientific literacy. Students' scientific literacy skills are presented according to content, science process, and context aspects. The increase in students' scientific literacy skills was analyzed based on the N-gain and paired sample t test. The results of the study found that students' scientific literacy skills in all content, science process, and contexts, were higher in the posttest than the pretest except for content energy that accompanies changes in material and context of natural resources. The average scientific literacy ability of students at the posttest (74.33) was higher than at the pretest (57.08). The N-gain value of 0.40 indicates an increase in students' scientific literacy skills with implementation of case method learning in the medium category. Analysis with paired sample t test indicates a significant difference in the pretest and posttest scores. Thus, it can be concluded that case method learning can improve students' scientific literacy skills in the three domains of scientific literacy.

Abstract

This research is a descriptive quantitative that aims to determine the understanding of science teachers and students' knowledge in solving creative thinking-oriented scientific literacy questions. The instruments used in this research were a teacher interview questionnaire and creative thinking-oriented scientific literacy essay questions. Teacher interview data were analyzed using a descriptive percentage, and student test results were analyzed using descriptive statistics by calculating the average percentage score for creative thinking-oriented scientific literacy skills based on scientific literacy indicators and creative thinking indicators. The results of the analysis show that 83.33% of teachers still rarely and almost never use scientific literacy and creative thinking assessments in science learning. Meanwhile, in the results of the analysis of the students' test data, the average percentage for the scientific literacy indicator was 22.86% and the creative thinking indicator was 23.23% with the predicate of very poor and in the low category. Thus, it can be concluded that the understanding of junior high school science teachers in Langsa City in developing creative thinking-oriented scientific literacy assessments is still low. This has an impact on the students' abilities, which show that the creative thinking-oriented scientific literacy skills are classified as very poor in the low category
