Enhancing Students` Technical Competence in Sketching Using Sketchbook Application

Abstract: Sketching is a fundamental skill in technical drafting, yet many students find traditional drawing methods challenging, time-consuming, and error-prone. The study examined the effectiveness of the Sketchbook application in improving the technical competence of Drafting and ICT students and their overall sketching performance. A quasi- experimental research design, specifically a single-group pretest-posttest approach, was utilized. The study involved 30 Grade 9 students who experienced challenges in technical competence in sketching. Their works were evaluated using a validated scoring rubric that was examined by the expert in the field. Based on the findings, the pre-test results showed a “Satisfactory” level of performance, indicating that students had basic sketching skills but still needed improvement. After the introduction of the Sketchbook application, the post-test results improved to an “Excellent” level, indicating a high level of competence in sketching. There was also a significant difference between the pre-test and post-test results, confirming an improvement in students’ performance. The effect size analysis revealed a large effect, indicating that the Sketchbook application had a strong and meaningful impact on enhancing students’ technical competence in sketching. Beyond improving their technical skills, it also fostered greater confidence and engagement in the learning process.
