Abstract

This research is an experimental study that uses a quasi-experimental design with a non-equivalent control group design research pattern. The purpose of this study was to determine the significant effect of learning the PhET simulation rock discovery model on learning outcomes in the cognitive domain of The Beauty of Diversity Theme in my Country Class IV at SDN Gebang 3. The subjects in this study were fourth grade students at SDN Gebang 3. The implementation of the research in odd semesters. 2022/2023. Data collection techniques used tests and documentation. Data analysis techniques are homogeneity test, normality test, t-test, relative effectiveness test. In data processing using SPSS 25 as a tool. The results of this study indicate that tcount > ttable i.e. 4,200 > 1,674, it can be concluded that there is a significant effect of using the PhET simulation-assisted discovey learning model on learning outcomes in the cognitive domain. 48% yield. This value is included in the moderate effectiveness criteri.

Abstract

Science literacy is an essential competency for primary school students to face 21st-century challenges. However, few assessment tools combine strong psychometric quality with cultural relevance. This study aimed to examine the psychometric properties of a local wisdom–based science literacy instrument for primary school students within the Item Response Theory (IRT) framework. The instrument comprised 34 multiple-choice items aligned with science literacy indicators and was administered to 300 fourth-grade students from several schools in Jember, Indonesia. Expert judgment ensured content validity, while empirical analyses using QUEST and R Studio evaluated item performance. The results showed good model fit, excellent reliability (0.97), and well-balanced item difficulty levels, confirming the instrument’s ability to measure a wide range of student abilities. Person–item maps and item characteristic curves indicated high discriminative power and measurement precision. Embedding local wisdom elements enhanced cultural authenticity and student engagement in science learning. Overall, the instrument demonstrated strong psychometric and contextual validity, offering a reliable tool for assessing science literacy in primary education. Its application can help teachers identify learning needs and design culturally responsive instruction. Future studies should extend validation to broader cultural contexts and refine items for students with lower ability levels.
