Abstract
Although communication scholars have begun to examine computer-mediated instruction, they have focused far more on students' behavior and content acquisition, rather than on instructors and instruction. Therefore, this study was designed to explore computer-mediated instruction from the perspective of the instructor. The explored research focused on two different forms of computer-mediated instruction: learning management systems (LMS) and streaming media. While both technologies are unique in nature, both are popular forms of computer-mediated instruction currently being used in institutions across the country. One hundred fifty-four instructors were surveyed on their perceptions regarding the affordances, constraints, effects with, and effects of the two technologies.-Ten follow-up interviews were also conducted with a convenient sample of respondents to facilitate interpretation of the themes that emerged from the survey data. Discourse analysis of survey data and the interviews revealed that college instructors perceive a limited set of affordances and constraints to be associated with using learning management systems and streaming media to teach. Likewise, a limited set of effects with technology and effects of technology were perceived to function when using learning management systems and streaming media for instruction. While some affordances, constraints, and effects were specific to one technology, other affordances, constraints, and effects were found to be related to both technologies.
