Noting that interactive video instruction (IVI) should not and cannot replace classroom instruction, this paper offers an introduction to interactive video instruction as an innovative technology that can be used to expand pedagogical opportunities in public speaking instruction. The paper: (1) defines the distinctive features of IVI; (2) assesses the effectiveness of IVI; (3) describes videodisc modules applicable for public speaking instruction; (4) provides information on equipment and costs for implementing IVI; and (5) suggests strategies for integrating video instruction into public speaking instruction. The paper concludes that IVI can provide effective oral communication instruction to students outside the classroom, thus allowing more time in the classroom for performance, feedback, evaluation, and discussion.
