THE EFFECTS OF USING THE FOUR NOBLE TRUTHS STRATEGIC DESIGN (DSNM) MODEL ON THE DEVELOPMENT OF CREATIVE PRODUCT DESIGN SKILLS AND WORK ETHICS OF GRADE 9 STUDENTS

Abstract

The objectives of this research were to: 1) compare the Creative Product Design Skills of Grade 9 students before and after receiving learning management; 2) examine the effects of the model on work ethics; and 3) study the satisfaction of Grade 9 students toward the learning management process using the Four Noble Truths Strategic Design (DSNM) Model. This research employed a quasi-experimental design. The sample consisted of 40 Grade 9 students from Wat Si Somboon Municipal School, selected via purposive sampling. Research instruments included learning management plans, a skill assessment form, and a work ethic assessment form. Data analysis was conducted using t-test for Dependent Samples. The results revealed that: 1) Post-learning design skills ( = 32.45, S.D. = 2.15) were significantly higher than pre-learning skills ( =18.20, S.D. = 3.40) at the .05 level ( = 24.15,  = 5.01). The empirical outcome demonstrated a substantial leap in students' initiative to create novel works and increased attention to detail, resulting from analytical thinking practice in the Cause of Suffering (Samudaya) stage and imagination in the Cessation of Suffering (Nirodha) stage. 2) Work ethics were at the highest level ( = 4.68, S.D. = 0.42), with concrete positive behavioral changes observed, particularly in responsibility and perseverance in problem-solving during practical application in the Path (Magga) stage. 3) Student satisfaction was at the highest level ( = 4.75, S.D. = 0.38). This reflects a significant impact: the process clarified the design thinking system into sequential steps, thereby reducing work confusion. Consequently, students developed an awareness and appreciation of applying local wisdom to create innovations.
