Abstract

This research focuses on the validity and reliability of the Two-Tier Test as a tool to measure misconceptions in science subjects, especially circulatory system material, among MIN students throughout Pontianak City. The research aimed to ensure that the Two-Tier Test used in this research provides valid and reliable results in analyzing student misconceptions through a reliability test. This research contributes to the development of a more specific, accurate and effective evaluation method for detecting misconceptions in science subjects, especially regarding the circulatory system. The research design adopts a Research and Development approach to create reliable measuring tools. The research subjects involved students who had studied the circulatory system material at MIN in Pontianak.  Sampling was carried out using a stratified random sampling technique through a Two-Tier Test and semi-structured interviews regarding the blood circulatory system. Test validity is measured using Gregory's theory, including content, criterion and construct validity. The research results show that the Two-Tier Test has optimal validity and high reliability. A validity score of 1 indicates the instrument's accuracy in measuring the targeted attribute.  The reliability of the test items, with a value of 0.71, is considered acceptable at a high level. The research conclusion shows that the Two-Tier Test is a reliable and consistent instrument for analyzing students' misconceptions, contributing to effective decision making in data analysis.

Abstract

This study aimed to describe the effect of applying the Science, Technology, Engineering, Art, and Mathematics (STEAM) strategy on students’ science literacy in the ecosystem material of grade V at SDN 44 Pontianak Barat. The research employed a quantitative approach with a quasi-experimental design type pretest-posttest control group design. The sample consisted of 52 students selected using a random sampling technique. Data were collected through observation, tests, and documentation, and analyzed using instrument analysis, prerequisite tests, hypothesis testing, and effect size measurement. The results showed that the average science literacy score in the control class increased from 42.08 (low) to 57.09 (moderate), while in the experimental class it increased from 49.02 (low) to 83.23 (high). Hypothesis testing obtained a significance value of 0.001 < 0.05, indicating a significant difference between the use of STEAM and conventional strategies. The effect size of Cohen’s d was 1.055 > 0.8, which falls into the large effect category. Thus, the application of the STEAM strategy has a positive and significant effect on improving elementary school students’ science literacy.
