Abstract
This article examines the influence of teacher/peer e-scaffolding in a mobile learning environment on students' design skills and the technology fatigue associated with a 3D virtual learning environment. The sample consisted of 32 postgraduate students who were divided into two groups according to their e-scaffolding source (teacher/peer). The findings showed that peer e-scaffolding outperformed teacher e-scaffolding in the mobile learning environment in terms of students' development of design skills. The findings also showed that students became moderately fatigued after designing the 3D virtual environments in both experimental groups. This study can act as a guide for teachers and instructional designers by helping them to select the most suitable e-scaffolding source when teaching 3D virtual environment design skills. This may result in better and easier skill development.
