Abstract

This study aims to measure and analyze the level of STEM literacy among prospective physics educators using Rasch measurement theory. A quantitative approach with a descriptive design was employed. The research instrument consisted of a STEM literacy test comprising multiple-choice questions and essays, and the data were analyzed using Winstep software version 5.7.1 to assess the validity and reliability of the measurement instrument. The results reveal that only a small number of prospective physics educators exhibit very high STEM literacy, while the majority demonstrate moderate to low levels of competencies and attitudes toward STEM literacy. The measurement instrument was confirmed to be valid and reliable according to Rasch parameters. These findings highlight the need for targeted interventions to enhance digital literacy, multidisciplinary skills, technology integration, and scientific competence among aspiring educators. Educational institutions are thereby urged to better prepare future educators to teach and promote STEM literacy effectively among students.

Abstract

This study aims to test the feasibility and effectiveness of implementing smartphone-based chemistry e-modules in enhancing high school students' understanding of the material, creativity, and collaboration. The research method used is pre-experimental with a one-group pretest-posttest design. The research sample consisted of 28 tenth-grade students at SMA Negeri 1 Tinombo, selected using purposive sampling technique. Data were collected thru instruments such as material comprehension tests, creativity tests, and collaboration observation sheets. The research results show that the implemented e-module meets the validity criteria with an average of 78% and is very practical to use, with a practicality score of 84.5% for teachers and 87.78% for students. The effectiveness analysis using the N-Gain test shows an increase in material understanding of 0.71 (high category). For student creativity, the N-gain value is 0.72, and for collaboration, it is reinforced by the teacher's observation results of 87.5%. Thus, it can be concluded that the smartphone-based e-module is effective in improving the quality of chemistry learning on nanomaterial topics.
