| Zusammenfassung |
| Conventionally, weather products utilized in synoptic meteorology reduce
phenomena occurring in four dimensions to a 2-dimensional form. This
constitutes a road-block for non-atmospheric-science majors who need to take
meteorology as a non-mathematical and complementary course to their major
programs. This research examines the use of Integrated Data Viewer-IDV as a
teaching tool, as it allows a 4-dimensional representation of weather
products. IDV was tested in the teaching of synoptic meteorology, weather
analysis, and weather map interpretation to non-science students in the
laboratory sessions of an introductory meteorology class at Western Michigan
University. Comparison of student exam scores according to the laboratory
teaching techniques, i.e., traditional lab manual and IDV was performed for
short- and long-term learning. Results of the statistical analysis show that
the Fall 2004 students in the IDV-based lab session retained learning.
However, in the Spring 2005 the exam scores did not reflect retention in
learning when compared with IDV-based and MANUAL-based lab scores (short
term learning, i.e., exam taken one week after the lab exercise). Testing
the long-term learning, seven weeks between the two exams in the Spring
2005, show no statistically significant difference between IDV-based group
scores and MANUAL-based group scores. However, the IDV group obtained exam
score average slightly higher than the MANUAL group. Statistical testing of
the principal hypothesis in this study, leads to the conclusion that the
IDV-based method did not prove to be a better teaching tool than the
traditional paper-based method. Future studies could potentially find
significant differences in the effectiveness of both manual and IDV methods
if the conditions had been more controlled. That is, students in the control
group should not be exposed to the weather analysis using IDV during
lecture. |
