Two things emerge in the study of students’attitudes toward online learning: individual situations impact students’ perceptions of computer-based learning, and students’ varied individual characteristics make it difficult to define their perceptions conclusively. For example, some students have their own computers, while others rely on computer labs. Such variation in computer access can result in attitudinal differences. In addition, the purpose of computer use varies. Distance education courses, for example, use computers in different ways than traditional classrooms, which can also affect students’ perceptions. A wide variety of achievement levels and attitudes exist among both online and traditional learners. Although an illusory “typical learner” exists, a variety of factors, including students’ gender, age, and motivation, could explain different reactions among the student population.
