Abstract

In the process of teaching Strength of Materials, students often find it difficult to understand and the level of achievement of the course learning outcomes is not high. Therefore, active teaching methods and application of computer aim to support students actively, proactively, and in project-based learning. This article presents the possibility of integrating the Mdsolids software in teaching strength of materials at Nguyen Tat Thanh University (NTTU) for students majoring in automotive engineering technology. The student satisfaction survey on the course and the application of Mdsolids in teaching were conducted and evaluated to test the effectiveness of active learning activities. The obtained results confirmed further evidence of the benefits of Mdsolids in supporting students to achieve the course learning outcomes.

Abstract

This study aimed to investigate the impact of problem-based learning with a focus on character development and naturalist intelligence on critical thinking (CT) abilities and curiosity of students. The study was conducted in a school in the city of Mataram - Indonesia, utilizing a 3x2 treatment by level design. Two groups of students, categorized as having high or low naturalist intelligence, were exposed to three different treatments: problem-based learning with character development (PBL-CD), problem-based learning, and regular learning. Data regarding the students' naturalist intelligence and CT abilities were collected through tests, while information on their curiosity was obtained through observation sheets and self-assessment. Statistical analysis using MANOVA at a significance level of 0.05 was performed. The findings revealed that: (a) PBL-CD had a positive impact on students' CT abilities and curiosity; (b) the naturalist intelligence did not significantly influence students' CT abilities and curiosity; and (c) there was no significant impact observed on students' CT abilities and curiosity when examining the interaction between PBL-CD and naturalist intelligence. Thus, PBL-CD presents itself as a viable strategy to cultivate students' critical thinking skills and inquisitiveness, offering an alternative pathway in routine learning in the classroom.

Abstract

Solar energy is available in abundance. It is considered an effective energy source for drying agricultural products. Although it is affordable, open sun drying suffers from both qualitative and quantitative issues caused by unexpected environmental conditions (rain, dust), animals (insects, birds, rodents), and over-or under-drying. Therefore, it is important to introduce a better drying technology to preserve solar energy without deteriorating the quality of the drying product. For that reason, solar dryers have been developed to produce higher drying temperatures and lower relative humidity that will eventually lead to superior drying rates and reduced final moisture contents compared to the conventional open sun drying method. Therefore, not only does the solar dryer meet the requirements of agricultural products, but it also saves energy, time, and money.
