This research aims to develop sensor and transducer e-modules based on 4Cs skills using the Kvisoft Flipbook application to improve the quality of learning in automotive engineering. The main focus of the research is to assess the validity, practicality, and student response to the e-module design developed. The research method used is Research and Development (R&D) with the ADDIE model. Data collection techniques included validation questionnaires, user practicality questionnaires, and student response questionnaires to the e-modules. The e-module was rated highly valid by 89% of e-module experts and 88% of material experts and highly practical according to the assessment of lecturers (89.09%) and students (81.81%). The evaluation showed that students who used the e-module achieved a higher average score than the control group, signalling the effectiveness of the e-module in improving critical thinking skills, communication, collaboration, creativity (4Cs), and material understanding. These findings emphasize the importance of technology integration in vocational education to prepare students for the challenges of the Industrial Revolution 4.0 and encourage innovation in teaching methodologies.

Extended reality for education: Mapping current trends, challenges, and applications

Agariadne Dwinggo Samala — 2024-08-31

The advancements in 5G technology and Artificial Intelligence (AI) have accelerated the integration of immersive technologies such as Extended Reality (XR) into educational practices. There is a notable scarcity of studies focusing specifically on the applications and impact of XR in academic settings. Most existing research has concentrated on AR and VR, leaving a gap in understanding the full potential of XR. Addressing these gaps and challenges is crucial for harnessing the full potential of XR in education. This study aims to map and analyze the applications, trends, and educational challenges of XR technology. This study conducts a bibliometric analysis covering XR's application in education from 2018 to 2023, analyzing 32 articles from Scopus sources. Key findings highlight XR's annual growth in research publications, with significant contributions from the United States, China, and Canada. XR enriches education by facilitating immersive simulations, real time interaction with virtual objects, and spatial manipulation in three dimensions. It fosters presence and embodiment in virtual environments, supports practical training through realistic simulations, enhances multi-sensory engagement, promotes collaborative learning environments, and improves accessibility for diverse learners. The main challenges of XR technology include high costs, technical hurdles, regulatory issues, infrastructure limitations, and the need for digital literacy and skills. Addressing these challenges, collaborative efforts among educators, researchers, and industry stakeholders are required. Such collaboration is crucial for harnessing the full potential of XR technology to revolutionize education and prepare learners for a dynamic future.

Enhancing STEM education through peeragogy: Exploring the impact of demographics factor

Nur Nadia Binti Md Arsad — 2024-08-31

Despite the growing recognition of the peeragogy learning approach, which emphasizes students' active participation and responsibility in their learning, there is still a gap in understanding how demographic factors influence its effectiveness in Science, Technology, Engineering and Mathematics (STEM) education. While pedagogy aims to harness the individual potential to promote independence, collaboration, and deep understanding, few studies have been conducted on how different demographic factors impact the success of this approach. This study aims to identify the trends in the peeragogy learning approach among students for STEM subjects in the Upper Secondary Vocational Program (PVMA) stream based on demographic factors such as gender, STEM subjects, and socioeconomic status (SES). The design of this study is survey research that employs a quantitative approach, and a modified set of questionnaires derived from past studies was used as the research instrument. A total of 158 students enrolled in STEM subjects under the PVMA stream at secondary schools were randomly selected as the study samples. The results indicate that most students in STEM subjects under the PVMA stream prefer a goal-oriented peeragogy learning approach, a consistent trend across both genders. Socioeconomic status also plays a role, with students from varying household income levels generally preferring the self-directed peeragogy learning approach. Different STEM subjects and SES affect PVMA students' choice of peeragogy learning approaches. In conclusion, educational institutions can improve the effectiveness of peeragogy in STEM education for PVMA students by promoting equitable learning opportunities for different SES and developing peeragogy strategies based on different STEM subjects.

A Study on the efficiency of organic activator application to process refractory hard-to-beneficiate raw materials

Kenzhaliyev Bagdaulet Kenzhalievich — 2024-08-31

Polymetallic ores with complex mineralogical compositions pose significant challenges in flotation beneficiation, often resulting in suboptimal separation and recovery of valuable minerals. This study aims to analyse the effectiveness of alkyl benzene sulfonic acid (ABSA) as a frothing activator in improving the flotation performance and mineral recovery of polymetallic ore. It presents the results of flotation beneficiation experiments for polymetallic ore of complex mineralogical composition. Experiments were conducted on polymetallic ore samples using ABSA as the frothing activator in the flotation process. The performance was evaluated based on recovery rates and separation efficiency, comparing the results with standard floating frothing agents. The findings showed the highest efficiency of ABSA application for samples of mixed-type ores in increasing the recovery of gold, copper, zinc and lead in the collective concentrates of flotation beneficiation. ABSA activator promotes additional cleaning of fragments containing valuable metals from oxide films and coatings and the transfer of valuable metals' microparticles due to the organics' adsorption properties and the formation of metal-carbon bonds. Another effect of using this reagent is there was an increase in concentrate mass yield while maintaining the quality parameters. A similar effect was observed for beneficiation of copper ore with complex composition - copper recovery in the main concentrate increased. Selective flotation with the development of gold concentrate from hard-to-beneficiate polymetallic ore also showed a significant increase in gold recovery with ABSA pretreatment.

Energy conservation strategies on academic buildings using interpretive structural modeling to develop energy sustainability

Yaumal Arbi — 2024-08-31

Effective energy conservation strategies are required to be implemented in academic buildings as they consume significant energy while considering the convenience and function of the buildings. However, the influencing factors are interrelated and complex, requiring an appropriate approach to unravel the complexity. Therefore, this study aims to identify, analyse, and map the interaction relationship between factors affecting energy conservation in academic buildings. This study used Interpretive Structural Modeling (ISM) procedure starting from developing the Structural Self Interaction Matrix (SSIM), converting SSIM into a Reachability Matrix, revising the matrix, and categorizing the factors by using MICMAC analysis. This study involved 9 factors, including architectural design, illumination technology, education and awareness, energy monitoring and management, renewable energy use, efficient HVAC system, energy-saving equipment, institutional policies, and campus community participation. The study found that renewable energy use at level 3 was the factor that was not influenced by and did not interact with any other factors. Meanwhile, the illumination technology was a factor that interacted with the efficient HVAC System factor which was at level 1 where these two factors were influenced by other seven factors. This study aligns with current developments in energy conservation, including an increased focus on renewable energy and energy efficiency in academic buildings, supported by global and national policies aimed at achieving sustainability goals. It provides a comprehensive understanding on developing sustainable energy conservation strategies in academic buildings.
