The second demo app provides a virtual laboratory and has the task for the learner to create a simple electrical circuit.
Feedback of the learners
The interaction with the virtual laboratory is difficult without an appropriate pointing device. This may be the reason for the feedback of smartphone (and also tablet) users.
Conclusion: Learning apps that make use of pointing devices are only partially suitable for smartphones (and tablets). In courses using these elements, learners should be informed about the problems of using smartphones or tablets before the start of the course.
