摘要：This study aims to analyze the differences in students' understanding of the science concept between predict-observeexplain and conventional learning, differences in students' understanding of science concepts between high and low curiosity, and the interaction impact between learning model and curiosity factors. The research approach used a quantitative approach with a Quasi Experiment methodology type 2x2 factorial design.The population of this study were fourth grade students in SD Negeri Keluarahan Nalumsari, namely SD N Nalumsari 1, 2, and 3. Furthermore, the sample was taken using the Cluster Random Sampling Technique with the acquisition of samples, namely fourth grade students at SD Negeri Nalumsari 1 and 2. The data was collected using the instrument for understanding the concept of science and a questionnaire sheet for students' curiosity, which was analyzed using the Two Way Anova provided that the data must be normally distributed and homogeneous. The results obtained are: 1) there are differences in students' understanding of the science concept between predictobserve-explain and conventional learning, 2) there is a difference in the understanding of students' science concepts between high and low curiosity, and 3) there is an interaction impact between the learning model and curiosity factors on the understanding of the science concept of fourth grade students at SD Negeri Keluarahan Nalumsari, Jepara.
