Abstract

This study aims to improve students' conceptual understanding. This type of classroom action research implements interactive digital media based on the Kahoot application. The subjects of the study were all fourth-grade students at SDN Ngasemlemahbang, totaling 16 students. Each cycle consisted of the stages of planning, implementation, observation, and reflection. The data analysis techniques used were observation result analysis and conceptual understanding analysis. The results of the study can be concluded as follows: (1) Teacher activity observation in Cycle I obtained an average score of 62.5%, and in Cycle II, it increased to 88.67%, showing an improvement of 26.17%. (2) Student activity observation in Cycle I obtained an average score of 58.33%, and in Cycle II, it increased to 89.16%, indicating an improvement of 30.83%. (3) Students’ conceptual understanding in Cycle I reached 56.25%, and in Cycle II, it increased to 81.25%, showing an improvement of 25%. Therefore, it can be concluded that the use of the Kahoot application in learning activities can improve students’ conceptual understanding in the topic of two-dimensional shapes in the fourth grade at SDN Ngasemlemahbang.

Abstract

This study aims to develop a valid and effective video-based learning media using Sparkol Videoscribe for teaching the Solar System topic in the sixth-grade science curriculum at SD Negeri 1 Lawak. The research employed a 4D development model (Define, Design, Develop, Disseminate). Data were collected using expert validation sheets, student response questionnaires, and student activity observation forms. The validation results showed that the developed media was highly valid, with media expert validation scoring 96%, design expert validation scoring 96%, and content expert validation scoring 96.5%. Furthermore, the student response instrument achieved a score of 94.5%, and the student activity instrument scored 95.5%. The media was also considered effective based on students’ active engagement and positive feedback during the learning process. Therefore, Sparkol Videoscribe-based learning media is deemed appropriate as an alternative instructional tool in science learning, particularly for abstract topics such as the Solar System.
