The present study was conducted to evaluate the effectiveness of video-assisted teaching on knowledge regarding online game addiction among school children aged 11–13 years in a selected school at Kannur district. Excessive involvement in online games has been shown to negatively impact physical, emotional, and academic performance. A quantitative research approach with a pre-experimental one group pretest post-test design was used. 30 students from classes VI and VII were selected via convenience sampling. Data were collected using a semi structured questionnaire before and after a 13minute video intervention. Pre-test results showed 43.3% inadequate and 56.67% moderate knowledge. Post-test results significantly improved, with 86.67% achieving moderate knowledge levels. The study concluded that Video Assisted Teaching is an effective educational tool for enhancing awareness.
