A database of 406 articles published in 2000 in 17 specialist higher education journals, based outside North America, is analysed in terms of whether a theoretical perspective is adopted. In the majority of cases, any theoretical perspective is only implicit, and broader engagement with theory is absent. Where theory is explicit, the authors…

The concept of statistical significance is explained, with specific numerical illustrations. (MNS)
