This article describes two interactive videodisc instructional programs for teaching organizational techniques in public speaking and reports the assessment of these programs. Formative evaluations indicate that students enjoyed the level III interactive video instruction (IVI). One-way analyses of variance indicated that students receiving IVI in "Constructing Speaking Outlines" (study 1) or "Developing Key Ideas" (study 2) achieved significantly higher recall/application test scores than did students in the control group in the respective study. Implications for the use of these IVI programs in supplementing traditional public speaking instruction are discussed.
