The validation results showed an average score of 91.6%, which falls into the category of highly valid and feasible for use in the learning process. Following the validation, a practicality test was also conducted by distributing questionnaires to 20 students in class IV A. Based on the results, a total score of 189 out of a maximum of 200 points was obtained, indicating an average practicality rate of 94.5%. This result suggests that the product is very easy to use and well-received by students.Based on the validation and practicality test results, it can be concluded that the assessment instrument using Quizizz PaperMode for IPAS learning on natural resources is highly feasible and practical to be used in teaching and learning activities at the elementary school level.
