Can remote labs teach engineering concepts as well?
These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
Group A N = 50
an experimental study (Fig. ) was conducted on two groups of students, group A (GA, N = 50) and group B (GB, N = 50), from the second year undergraduate (UG) mechanical engineering course.
CUQ maximum score of 14
Each correct answer earned 1 point and a student could score a maximum of 14 from the CUQ questionnaire.
What they did
Researchers compared physical-lab and remote-triggerable universal testing machine platforms with two randomly grouped cohorts of second-year mechanical engineering students. Students completed a conceptual understanding questionnaire worth up to fourteen points before and after lab experiences, and the team also examined interactivity patterns and platform effectiveness using transactional-distance ideas.
What they found
Pre-test conceptual scores did not differ significantly between groups. After physical-lab work, average conceptual scores rose sharply, and completing the same experiment on the remote platform produced a further gain for a large cumulative increase. Remote students finished assignments in less time, while physical labs showed more student-student interaction.
The limits
What it doesn't show
Participants came from one mechanical engineering course using a specific UTM setup, so results may not transfer to other labs or disciplines. Sequencing physical then remote experience for one pathway limits claims about remote-only first exposure and long-term retention.
Key terms
- Remote-triggerable UTM
- A laboratory setup that lets students operate a universal testing machine through a networked interface rather than only hands-on controls.
- Transactional distance
- The psychological and communication gap between instructor and learner in remote settings, shaped by structure, dialogue, and autonomy.
- Conceptual understanding questionnaire (CUQ)
- A scored set of items used here to measure students' grasp of UTM-related mechanics concepts before and after labs.
- Physical lab (PL-UTM)
- The on-site laboratory condition where students perform UTM experiments in person.
- Interactivity
- Exchanges among students, instructors, and equipment during laboratory work.

How large were the two student groups?
Common questions
Did remote labs replace physical labs entirely in the strongest reported pathway?
One group first completed the physical experiment, then the remote one; remote practice added further conceptual gains after physical experience.
Were the two student groups equivalent at the start?
Yes—pre-test conceptual scores showed no significant difference between groups.
What trade-off appeared in interaction?
Remote work was faster, but physical labs had more student–student interaction.
How was conceptual learning scored?
Each correct CUQ answer earned a point, for a maximum of fourteen.
