ABSTRACT

Background:

Mental rotation is a cognition related to spatial ability and career developments in STEM-related fields. It can be enhanced by using VR-assisted training technology to practice MR tasks.

Objective:

This study created a theoretical model to explain the processes of accepting a novel VR-assisted training system for mental rotation, in hopes to better understand how to encourage learners to use it to enhance their spatial ability.

Methods:

Stereo and Interactive Mental Rotation Tasks (SIMRT) based on Shepard and Metzler’s pencil and paper-test for MR ability were created. The participants conducted a set of MR tasks by using a 3D glasses/stereoscopic display and a six-degrees-of-freedom joystick controller. Followed by the practice, psychometric constructs from theories and prior studies (i.e., perceived-ease-of-use, perceived enjoyment, attitude, satisfaction, behavioral intention to use the system) were used to measure relevant factors influencing behavior intentions.

Results:

The statistical technique of partial least square – structural equation modeling (PLS-SEM) was applied to analyze the data. The model explained 47.7% in the novel, VR-assisted MR training system’s adoption intention, which suggested a moderate explanatory power. Direct and indirect effects were also interpreted.

Conclusions:

Theoretical contributions and future studies in VR-assisted education/training are discussed. Implications for educators and technology developers regarding the application of VR technology for mental rotation are also provided in the paper.
