This study examined the factors that contribute to learners' perceptions of the ease or difficulty of learning a specific task using a specific medium were studied, specifically whether the preconceptions of preservice teachers vary by learning domain (verbal, intellectual, affective, and psychomotor) or medium of presentation (interactive video, computers, television, and books). Forty-two female undergraduates rated the difficulty of learning through the four media and assessed preconceptions of the difficulty of each medium for each domain. Participants viewed the media as very different in their ease of learning, and considered that the ability of the medium to present actual models demonstrating the desired behavior was very important.
