Continuing developments in educational technology and increasing undergraduate numbers in the UK have facilitated the use of computer-based learning packages. One of the effects of the increasing use of these packages is the shift in teaching of material from being primarily lecturer-led to student-driven. This has a number of implications concerning using the package, since it is quite likely that students will be working in isolation, and the use of the package may be mandatory or optional. In this study we report on the usefulness ratings of a software package for undergraduate use within the context of whether or not students choose to use it. Level 1 students and lecturers in Economics were surveyed at three UK universities. Findings indicate that students whose use was mandatory rated the learning package as more useful than those whose use was optional. Reasons for non-use centred on lack of instruction and on student apathy. These results have important implications for the use of computer-based learning packages and for understanding user attitudes.
