Remote engineering lab for teaching computer systems engineering: Evaluation and impact

We developed a remote engineering laboratory and exercises to teach field-programmable gate array based microprocessor and interfacing course of study aiming for students to gain individual learning experiences. The course was delivered entirely online without conceding traditional learning outcomes. The web interface of the remote lab allowed students to interact with remote field-programmable gate array boards installed in the laboratory from any location. Cameras were installed as part of the setup to capture the events on these boards in response to student programs and operations. Five sets of NIOS-II laboratory exercises were developed for teaching microprocessors at an intermediate level. Instructions and related demonstration videos were prepared and uploaded to the course moodle page so that the students could work on the exercises independently without an instructor or a physical lab. The student learning experience was evaluated using quantitative feedback scores and real-time user access data. One hundred thirty-four students were enrolled on the course during 2020 and 2021. The study showed that remote labs and related exercises enhanced student engagement in the course. Students appreciated the remote lab resource that supported them in achieving individual learning experiences. Unlike the restricted lab hours practiced during traditional on-campus teaching, the remote lab offered 24 h access to lab resources. Thus this provided flexibility for the students to experience the lab on their own time and allowed them to practice lab exercises several times.
