Examining some assumptions and limitations of research on the effects of emerging technologies for teaching and learning in higher education

This article examines assumptions and beliefs underpinning research into educational technology. It critically reviews some approaches used to investigate the impact of technologies for teaching and learning. It focuses on comparative studies, performance comparisons and attitudinal studies to illustrate how under-examined assumptions lead to questionable findings. The extent to which it is possible to substantiate some of the claims made about the impact of technologies on the basis of these approaches and methods is questioned. We contend researchers should ensure that they acknowledge underlying assumptions and the limitations imposed by the approach adopted in order to appropriately interpret findings.
