The Development of an Online Lesson on Basic Canva Usage Integrated with Project-Based Learning for Mathayomsuksa 3 Students

Abstract

The purposes of this research were to: 1) develop an online lesson on basic Canva usage integrated with project-based learning for Mathayomsuksa 3 students; 2) compare students’ learning achievement before and after learning by developed online lesson integrated with project-based learning; and 3) evaluate the quality of the PR School Project presentation slides designed and developed by the students using Canva after learning with the developed online lesson integrated with project-based learning. The sample consisted of 23 Mathayomsuksa 3/1 students studying in the second semester of the 2025 academic year at Wat Takong (Ratbamrung) School, obtained by cluster random sampling using the classroom as the sampling unit via the lottery method. The research instruments included an online lesson, project-based learning lesson plans, quality assessment forms for content and technical aspects, a learning achievement test, and a project quality assessment form. The data were analyzed using mean, standard deviation, and t-test for dependent samples. The research results revealed that: 1) The overall quality of the developed online lesson integrated with project-based learning was at a good level (x ̅ = 4.25, SD = 0.80). Specifically, the content quality was at a good level (x ̅ = 4.21, SD = 0.80), and the technical quality was at a good level (x ̅ = 4.35, SD = 0.75); 2) The students’ post-test learning achievement was significantly higher than their pre-test achievement at the .05 statistical level (t = 15.34) and 3) The overall quality of the PR School Project presentation slides created using Canva was at a good level (x ̅ = 3.10, SD = 0.61).
