Ra. Avila et al., COURSE MATERIALS PRESENTATION USING VIDEO-BASED TECHNOLOGIES - AN EVALUATIVE STUDY OF COLLEGE-STUDENT PERFORMANCE AND ATTITUDES, Psychology in the schools, 32(1), 1995, pp. 38-45
A study was conducted in which one group of students was taught for 4
weeks using computer-generated lecture-relevant visual materials (i.e.
, still color video-displayed graphics) and then for 4 weeks using tra
ditional lecture-relevant visual materials (i.e., blackboard and overh
ead transparency drawings). During the same time period, a comparable
group of students was taught the same material by the same instructor
for 4 weeks using traditional lecture-relevant visual materials and th
en for 4 weeks using computer-generated lecture-relevant visual materi
als. Students' learning of the course material (i.e., operationalized
in terms of examination scores) and their attitudes about the course a
nd instructor were assessed after the first 4-week period (Time 1) and
the second 4-week period (Time 2). The pattern of exam score results
suggested that student learning was negatively affected from Time 1 to
Time 2 for those first having, and then not having, the computer-gene
rated visuals and was positively affected from Time 1 to Time 2 for th
ose first not having, and then having, the computer-generated visuals.
Statistical tests performed on the data, however, did not reach accep
table levels of significance. Student attitudes did not parallel the p
erformance data. Implications of the results are discussed.
