ANALYSIS OF CRITICAL THINKING SKILLS AND COLLABORATION OF ELECTRONIC ENGINEERING EDUCATION STUDENTS IN ELECTRICAL MACHINERY COURSE

The development of the 21st century is directed at the specialization of certain abilities. This certainly influences the goals of Indonesia's national education, where graduates must be equipped with 21st-century skills. These 21st-century skills we can call the 4Cs, namely critical thinking (critical thinking), collaboration (collaboration), creativity (creativity), and communication (communication). The ability to collaborate and think critically needs to be applied in the learning process, including in the Electrical Machinery course. In the Electrical Machines course, lectures are conducted using an electric machine trainer. The use of this trainer is intended to create a student-centered learning atmosphere. To analyze students' critical thinking and collaboration skills in the electrical machine course, we conducted a series of studies related to this. The research method used is a quantitative research method with a one-shot case study research design. From the research, it was found that learning activities using an electric machine trainer were able to optimize students' critical thinking skills. This is because learning using a trainer is student-centered learning, where students play an active role in the learning process. Besides being able to optimize student collaboration skills because the learning process is carried out in groups. Discussion activities carried out in groups provide experiences for students to develop collaboration skills.

Determination of Continuous Earthmoving Machinery Course Stability under the Conditions of Cyclic Lateral Loading

This article presents the results of complex theoretical and experimental studies on creating universal continuous earthmoving machinery operating under non-standard loading conditions, namely, cyclic lateral loading on the actuator during digging. The lateral loading is due to the complex nature of the actuator motion when digging the soil, namely, the longitudinal motion of the machinery, the actuator digging the soil, and the lateral reciprocating motion of the actuator. This allows for variable width excavations in the soil, whose width exceeds the width of the actuator. The key issue of this machinery operation is to provide its course stability. The article considers the choice of soil-developing actuator and shows the developed calculation schemes of external loading on the operating equipment and a base tractor when digging long excavations in the soil. The dependencies to define external forces acting on the actuator when digging the soil and determining the machinery course stability, considering their spatial nature, have been developed and suggested for practical use. The conditions to ensure the stability of the course of universal earthmoving machinery have been formulated and substantiated. The developed method for determining course stability can be used when creating industrial samples of trenching earthmoving machinery.

A design of machinery learning activity to develop critical thinking

In engineering education, it is universally recognized that the development of higher-order thinking skills must be encouraged. On the one hand, the backwards design approach allows for the design of courses or activities focused on learning goals rather than on specific content, establishing basic tools to foster these skills. On the other hand, Bloom’s taxonomy allows for the separation of macro learning goals into specific learning objectives and adequate evidence. This work integrates the two approaches for the development of an active learning activity for a design of machinery course. The activity consists of introducing students to the design of mechanisms, is developed following the backwards design process and Bloom’s taxonomy of learning objectives, and focuses on both technical skills and critical thinking. After designing and testing the activity, the authors found that it allows the acquisition of technical skills in kinematics and kinetics of mechanisms and provides insights for the development of the main components of critical thinking within the machinery design process.

Digital homework for kinematics and dynamics of machinery

A digital homework program applicable to the study of kinematics and dynamics of machinery has been developed and successfully incorporated into an ongoing kinematics and dynamics of machinery course providing students with regulated self-practice, formative feedback, and partial credit scoring. The use of digital homework in upper-level engineering courses is sparsely documented in the literature but can provide homework assignments that give immediate feedback for self-assessment of learning while significantly reducing the time required of the instructor for grading. This paper presents a procedure for creating a digital homework set generally applicable to engineering courses using a commercially available course management tool. The paper then documents a specific implementation into a junior-level kinematics and dynamics of machinery course. This implementation is assessed over four semesters based on its comparison with traditional homework as perceived by students. The responses indicate that students were acquainted with digital homework from pre-engineering courses and did not regard the digital format as a hindrance. However, students perceived no benefit to the immediate feedback and, therefore, preferred the traditional format of upper-level courses. This perception is attributed to students’ tendency to make use of the homework feedback much later after the assignment and primarily at the point of exam preparation. However, this seems to be counter to the role of homework as a formative feedback tool that students use in real time to gauge and regulate learning activities. The authors conclude that the presented digital homework is both efficient and appropriate as a teaching supplement to an upper-level kinematics and dynamics of machinery course in the light of the role of homework as a tool to regulate learning of course material. Examples of the implemented digital homework problems are provided to serve as a resource for other instructors.
