Data were collected on student attitude changes that occurred over the yearlong course in
chemistry using the High School Chemistry Student Opinion Survey (Heikkinen, 1973). The results
showed that all students entered chemistry with a basically neutral attitude toward the subject.
It was hypothesized that students who experienced the video-enhanced treatment would
show a significantly higher positive attitude change than their peers in the control classrooms
based on the research purporting that video media is influential in raising students’ motivation
levels (McNeil & Nelson, 1991). Table 4 conveys the descriptive attitude pre- and posttest results
as measured by the High School Chemistry Student Opinion Survey.
