The fourth industrial revolution and the rise of collaborative robots (cobots) in industrial assembly lines are changing the traditional role of human operators in assembly tasks from following a sequence of operations to working together with a cobot and being able to intervene at different stages of the assembly process. Hence, it is important…

As virtual reality (VR) technologies have been increasingly adopted in the educational field, careful consideration and evaluation of instructional modes to support learning with VR are needed. This study focuses on evaluation of two instructional modes: direct interaction and manipulation of the VR learning environment; and the vicarious approach…

Students encounter many obstacles during scientific discovery learning with computer-based simulations. It is hypothesized that an effective type of support, that does not interfere with the scientific discovery learning process, should be delivered on a "just-in-time" base. This study explores the effect of facilitating access to…
