Does the use of computer-aided learning tools affect learning performance?

Studies comparing the learning performance differences between traditional courses and courses using computer-aided learning tools frequently give conclusions with reservations, indicating the possibility of other underlying factors that have a greater effect on learning performance than simply the medium used for content delivery. We analysed a uniquely assembled dataset covering a large number of university courses to revisit the media/method debate in the context of the effect of computer-aided learning tools on learning performance. Our results show that factors such as course type (determined by the content delivery medium), course subject, course level and student age all impact learning performance.
