Abstract

Enhancing managerial skills and creativity is crucial for students in technical fields in the rapidly evolving industry. This study explores the impact of project-based learning (PBL) on students' managerial skills and creativity in CNC machining engineering. The research employs a factorial exposure design, focusing on three key variables: project-based learning as the independent variable, managerial skills as the dependent variable, and creativity as a mediating variable. Data were collected using a Likert scale and analyzed through linear regression techniques. The research involved two classes from grade 11 in the machining engineering department of SMK YPI Darussalam 1 Cerme, which engaged in PBL activities. The findings reveal that project-based learning significantly influences students' managerial skills and creativity. While PBL's effect on managerial skills remains substantial, even when creativity is considered a mediating variable, creativity itself does not significantly mediate this relationship. This suggests that while PBL effectively enhances managerial abilities, it also promotes creativity in students, contributing to a richer educational experience. These results highlight the effectiveness of PBL as a pedagogical approach in the CNC machining curriculum. Although creativity does not moderate the relationship between PBL and managerial skills, PBL is valuable in developing both technical skills and creative potential, thus preparing students to meet future industry challenges effectively.

Abstract

Moodle is an open-source learning management system (LMS) or e-learning platform that is designed to help educators create online courses with various features to facilitate learning. Interest in this research area has increased significantly in recent years, leading to an increasing number of schools employing this LMS. In the early stages of the development process, schools need to gain insights into user needs and generate new ideas for designing and developing interactive LMS. In this light, Design Thinking (DT) is viewed as an important approach. This study aimed to design and develop an online learning system based on Moodle to facilitate online learning for elementary school students. The objectives were to (1) design a system diagram, system architecture, and functional structure for facilitating online learning and (2) develop an interactive LMS using Moodle. The research methodology was conducted following the DT process. An evaluation was made to assess the usability of the system using the Computer System Usability Questionnaire (CSUQ). Across dimensions such as system quality, information quality, and interface quality, scores ranged between 5 and 7, highlighting a positive user perception across various aspects of the evaluation. These findings, therefore, offer practical guidance for educational stakeholders in adopting and promoting Moodle-based LMS.

Abstract

Requirements engineering is a crucial phase in software development. In theory, requirements gathering should follow structured and systematic steps to ensure all requirements are complete, consistent, and clear. However, there is a lack of research in real-world contexts, particularly in small and medium-sized software development organizations, which often face challenges related to human resources, infrastructure, and financial constraints. This study aims to explore the practices of requirements engineering in software development agencies. A qualitative approach was used, employing a narrative (descriptive) research design. Data were gathered through interviews, observations, and documentation from six institutions involved in developing various types of software. The data were then analyzed using Yin's Five Cycle content analysis method, supported by Nvivo 12 software. The findings reveal that the time required for gathering requirements varies between institutions (four institutions take 1 week to 1 month, two take 1 to 3 months, and two take over 3 months). Regarding the analysts' backgrounds, all institutions consider requirements elicitation a critical stage in software development, leading them to hire analysts with IT educational backgrounds, most of whom possess significant work experience. This is further evidenced by the fact that all institutions consider staff experience when forming requirements analysis teams and assigning senior staff to specific roles. There is limited practical variation in the sources of requirements and elicitation techniques. All institutions rely on objectives, domain knowledge, stakeholders, and the operational environment as sources of requirements. As for elicitation techniques, they primarily use interviews, facilitated meetings, and document reviews.

Abstract

This paper fills an essential gap in applying cognitive load theory in teaching computer programming within vocational settings. It is an important area to consider for improving students' learning processes who intend to enter the rapidly changing technology sector. This study assessed the distinct impacts of the instructional paradigms, specifically Example-Problem-Based Learning (EPBL) and Problem-Based Learning (PBL), on students' cognitive loads upon framing an iterative structure lesson on computer programming. Vocational programming education is chosen for this purpose because vocational education faces unique challenges in integrating practical skills development with theoretical understanding, and programming tasks involve high cognitive demands. In a quasi-experimental design, 68 vocational high school students were assigned to an EPBL (n = 34) and a PBL (n = 34) group. The measurement of ICL was operationalized by RPI, the ECL by ME, and the GCL by LO. The relationship among the various components of the cognitive load was tested using the Spearman correlation test. There are significant differences in the profile of cognitive load between the two groups: the EPBL group was always associated with the lower ECL and higher GCL. In other words, the present study is original because it systematically compares EPBL with PBL in the context of vocational programming education and provides empirical evidence based on instructional design decisions. These findings suggest a further refinement of the CLT within domain-specific contexts and practical guidelines for optimizing instructional strategies in computer programming education in vocational schools.

Abstract

We present a response surface method to evaluate multi-objective optimization for MEMS-based microheater design. Box pattern, the standard microheater shape, was selected in this study since it has a uniform temperature distribution compared to other patterns. The optimum parameters are used to obtain the maximum total current density and Joule heat.  Based on a hybrid of the Response Surface Method and Central Composited Design, the model simulation emerged with 25 sets of Design Experiments.  As expected, the voltage is proportional to the increased output temperature and Joule heat of the microheater. Material thermal conductivity, anchor length and thickness of the heating element are included as design variables for the optimization. The microheater thicknesses of 4.23 - 4.55 µm, length of 40 µm and thermal conductivity of materials of approximately between 52 to 66 Wm-1K-1 became the optimized results at 1 V input voltage to obtain a maximum Joule heat of 4.9x105 W/mm3 and total current density of 5.6x107 mA/mm2.
