Development of Line Drawing Skills Using Online Video Media Based on the Flipped Classroom Model for Grade 8 Students at Watjantrawat (Sukprasarnrat) School.

Abstract

This article aimed to ; 1) develop drawing learning activities using online video media based on the flipped classroom model for grade 8 students at Watjantrawat (Sukprasarnrat) School, and 2) compare students' drawing skills before and after the learning activities. This was an action classroom research. The sample consisted of 39 grade 8 students in the first semester of the 2025 academic year. The research instruments included a lesson plan using online video media based on the flipped classroom model, a drawing skills assessment covering proportion accuracy, line consistency and continuity, light and shadow control, and image completeness, and a learning record sheet. Data were analyzed using mean, standard deviation, and pre- and post-test comparisons. The research results found as follows; 1. Students' drawing skills improved significantly after the intervention compared to before the intervention at the .05 statistical significance level. The average post-intervention evaluation score was at a high level (x ̅ = 4.26, S.D. = 0.45). 2. Most learners had similar evaluation scores, reflecting the consistency of overall class development. 3.The use of online video-based learning activities in a flipped classroom model can promote active learning, allow learners to review content independently before practicing in the classroom. This approach is suitable for teaching visual arts at the secondary school level.
