Abstract

The intention of the researcher was to study the effect of interactive television (ITV) in selected high school classes, using both quantitative and qualitative research techniques. The ITV network chosen for study was the Northwest Educational Technology Cooperative (NETC) operated by seven school districts in northwestern Minnesota (Argyle, Hallock, Kennedy, Stephen, Valley North (Alvarado and Oslo), and Warren). This system uses two-way interactive video and audio technology networked by fiber optics. Classes selected included Spanish I, Spanish II, and probability and statistics. Data collection was done during the fall semester, 1990.Quantitative methods compared means of scores achieved on pre-tests and post-tests by students in the selected classes reported by delivery mode and class site. Statistical techniques included analysis of covariance incorporating multiple regression techniques, as well as analysis of t-test values using Tukey's test. Research questions centered around class mode (traditional vs. ITV), class site (teacher physically present (host) vs. teacher on television (remote)), subject matter (linguistic vs. numeric and beginning vs. advanced), and class size (large vs. small).Results of all quantitative data analysis showed no significant differences in any circumstances tested. From this it could be said that no differences were found in measured learning whether the subject matter is linguistic or numeric, beginning or advanced; whether classes are small or large, traditional or ITV networked; and whether the teacher is physically present or pictured on a television screen.Qualitative techniques included interviews with selected students, teachers, and administrators as well as class observations. Questions explored the opinions expressed about ITV by students, teachers, and administrators involved. Results of informal interviews indicated overall positive attitudes toward this class delivery technique.Further research suggested by this study includes a continuing attempt to differentiate between students, teachers and subject matter that are well-suited to ITV networked classes and those that are less well-suited to the system.
