Multimedia courseware: never mind the quality how much will it cost to develop?
Baker (1994) humorously described the failure of teachers, companies, organizations and governments over the last twenty-five years to deliver the volume of courseware which would spark the active-learning revolution. Hardware now exists to deliver multimedia, but the cost of developing quality courseware remains high. What chance does multimedia-based active learning have of widespread adoption if developers cannot reliably estimate the development effort of multimedia courseware? This paper presents expert estimation of development effort to learner time ratios found in the literature, before investigating four alternative methods for estimating multimedia development effort. The results of the estimates are then compared against the actual project data.
