Circuit Theory E-Assessment Realized in an Open-Source Learning Environment

Abstract

This study discusses university-level e-education on circuit theory. Automatic assessment activities were realized in the learning environment Moodle with symbolic math enhancement plugin STACK. With a comprehensive set of self-study e-assignments, the desired outcome was to help the students to improve their conceptual understanding. Here, the instructional approach is to assign take-home e-activities during the course. The rationale for such approach is to guide the student to prepare themselves for the final exam. This study compares the learning results with the previous year’s traditional paper exams. E-activities can improve learning, but a lot of attention must be paid to two issues: realizing the activities and students’ learning skills. Moreover, the structure of a circuit theory e-quiz differs from a typical mathematics quiz, which is also discussed here

“…Another difficulty occurs when the students start experimenting with AC circuits and must start calculating with phasors and complex numbers. As stated in Neitola"s study (2019), the University of Oulu has had similar problems when teaching circuit analysis (Neitola 2019).…”

Meclib: Dynamic and Interactive Figures in STACK Questions Made Easy

“…Even though STACK was developed with focus on mathematics, it's built-in support for physical units and for interactive graphics make it interesting for application to other fields in engineering education [7], [8].…”

“…Randomization can be obtained by saving multiple versions of a question and using the random picking mechanism in the Moodle test activity. Also, random picking of multiple embedded image files has been reported [7]. In the Meclib approach, the image is defined by a list of object specifications, see Figure 5.…”
