In a recent contribution to the British Journal of EducationalTechnology colloquium,TimothyTeo (2009a) discusses the Technology Acceptance Model (TAM; Davis, Bagozzi & Warshaw, 1989), which is ‘arguably one of the most widely adopted and tested across organisational contexts, technologies and cultures’. On the one hand, there is empirical evidence that supports the role of attitude towards computer use (ATCU) as a mediator between the perceived usefulness (PU)/ perceived ease of use (PEU), and the intention to use the computer (eg, Teo, 2009b). On the other hand, in a technology acceptance study with n = 442 pre-service teachers,Teo (2009a) finds that, even if ATCU is correlated with the other model variables, it does not contribute to the overall variance in usage. Therefore, Teo regards ATCU as unnecessary for the TAM. He points at later models, such as the Unified Theory of Acceptance and Use of Technology (UTAUT; Venkatesh, Morris, Davis & Davis, 2003),where although ATCUwas found to be a significant predictor of the intention to use technology, it was removed from the model as being implicitly contained by other predictors, such as the performance expectancy (PE) and effort expectancy (EE). In conclusion, the role of the attitude construct for the technology acceptance models still has to be clarified. The aim of the present study was to examine the role of ATCU for acceptance models using Teo’s (2009a) method. We collected similar data for another, ongoing study aimed at verifying the UTAUT (Nistor, Wagner, Istvanffy & Dragota˘, in press), where the ATCU was additionally measured but not yet used for the model validation. The samplewas larger, bicultural and the age of the participants varied in a wider range.
