Abstract

Computer-based instruction (CBI) was considered the technological phenomenon to revolutionize education and training. Today, the Internet and computer technology are reported to have significantly altered the education landscape (Johnson & Aragon, 2002). The rapid advances in technology, the need for lifelong learning, and the growth of non-traditional students have encouraged the use of the computer as a method of instructional delivery. Evaluating the effectiveness of CBI as a whole technology is very difficult. The inability to measure effectiveness is attributable in part to the fact that CBI is not just one component, but a complex range of services and activities carried out for instructional and learning purposes (Gibbons & Fairweather, 2000). This study presents a theory of critical components that impact the effectiveness of computer-based instruction for adults. The theory was developed to provide a framework for research to explain or predict effective learning by adults using a desktop computer. The five conclusions drawn from this research are: (1) the characteristics of self-directedness and computer self-efficacy of adult learners play an important role in designing CBI for adults; (2) learning goal level impacts instructional design strategy and instructional control component of CBI design; (3) external support and instructional support are needed to provide a positive CBI experience; (4) CBI design is interwoven with the units of self-directedness, computer self-efficacy, learning goal level, instructional design, and external support; and (5) the theory draws together the isolated variables researchers consider important in the adult learning process and aligns them to provide effective CBI.
