Nusukan Primary School primarily utilises conventional teaching methods, with limited incorporation of technology. The objective of this study was to evaluate the efficacy of the Kahoot-supported Inquiry-Based Learning model in enhancing the problem-solving skills of primary school students. Employing a quantitative approach with a quasi-experimental design, the research was conducted with two third-year classes at Nusukan Primary School. The experimental group received instruction through the Inquiry-Based Learning model integrated with Kahoot media, while the control group was taught using conventional methods supplemented by PowerPoint presentations. Data were collected via pre- and post-intervention problem-solving assessments to measure the comparative effectiveness of the instructional approaches. The findings of this study indicate that the experimental group, which received instruction through the Kahoot-supported Inquiry-Based Learning model, demonstrated significantly superior problem-solving abilities compared to the control group. The experimental group achieved an N-Gain score of 78%, classified as 'effective,' whereas the control group recorded a score of 38%, deemed 'less effective.' Furthermore, the integration of Kahoot media enhanced the efficacy of the Inquiry-Based Learning approach, particularly during the second phase (organising students) and the concluding phase. This enhancement contributed substantially to the improvement of problem-solving skills among primary school students.
