The research aims to design and develop learning innovation to enhance higher order thinking skills for students in Thailand junior high schools. The design development research model of Richey and Klien (2007) is used and divided into two phases: (1) to design and develop innovative learning and validate of its quality based on the interviews and survey from 13 experts, 10 teachers and 30 students, and (2) to test the tools' validity by three experts and 153 students from five junior high schools at five provinces in Thailand. The findings indicate that analytical thinking, creative thinking, problem-solving thinking and critical thinking skill are developed by researchers, and experienced and practiced by learners in their lessons. The higher order thinking skills of learners after experiencing the learning innovation have a higher average score than the previous one. Following the students' perspectives on the learning innovation, 1) The design of content is in line with students’ knowledge levels, easy to understand, and enable to connect science contents to their daily life. However, some contents cannot fully cover into all classroom lessons; 2) Multimedia. A navigation design is easy for students to find information and direct to their needs. The icon symbols could hint the meaning of various information sources and have links to these sources. Also, multimedia could considerably explain scientific processes and help students understand better; 3) The design of problem scenarios supports easier connection to the daily life. In addition, using videos as a learning resource could suitably illustrate scientific process, and improve communicative and collaborative skills in problem solving.

In this study, we constructed a new algorithm to determine the optimal parameters for friction stir welding including rotational speed, welding speed, axial force, tool pin profile, and tool material. The objective of welding is to maximize the ultimate tensile strength of the welded aluminum. The proposed method combines the response surface method and the modified differential evolution algorithm (RSM-MDE). RSM-MDE is a method that involves both experimental and simulation procedures. It is composed of four steps: (1) finding the number of parameters and their levels that affect the efficiency of the friction stir welding, (2) using RSM to formulate the regression model, (3) using the MDE algorithm to find the optimal parameter of the regression model obtained from (2), and (4) verifying the results obtained from step (3). The optimal parameters generated by the RSM-MDE method were a rotation speed of 1417.68 rpm, a welding speed of 60.21 mm/min, an axial force of 8.44 kN, a hexagon-tapered tool pin profile, and the SKD 11 tool material. The ultimate tensile strength obtained from this set of parameters was 294.84 MPa, which was better than that of the RSM by 1.48%.

This study addresses the challenge of integrating digital tools with constructivist learning to enhance creativity in music education, a field where traditional pedagogies often fall short in meeting modern learners’ needs. The research aims to develop and validate a ubiquitous learning framework grounded in constructivist principles, focusing on fostering creativity and music arrangement skills among Thai high school students. Utilizing a quasi-experimental, mixed-methods design, the study involved 200 students, divided equally into experimental and control groups, from 10 schools across five provinces in Northeast Thailand. The framework, comprising six key components - Problem Base, Learning Resources, Cognitive Tools, Collaboration, Scaffolding, and Coaching - was iteratively developed and refined through expert validation (CVI = 0.94). Quantitative analysis revealed significant improvements in creativity dimensions, particularly in flexibility (t = 13.02, p < 0.001) and elaboration (t = 10.76, p < 0.001), with scaffolding and cognitive tools emerging as key predictors. This study contributes a validated framework that bridges the gap between traditional and technology-enhanced music education, offering scalable applications in diverse learning contexts.
