Abstract:
The effectiveness of static versus dynamic learning material was tested using fish
biodiversity as learning domain. Eighteen fish species were presented either as videos or
selected freeze-frames to students. Thereafter, students exercised identifying these species in
their natural habitats during snorkeling. Students’ knowledge of biodiversity was measured
from test videos before (posttest 1) and after (posttest 2) snorkeling as the number of
recognized species. Results showed significant knowledge gains between posttest 1 and 2. For
the presentation format (static vs. dynamic) there was no significant main effect. However, a
significant interaction showed that the students` knowledge improved from posttest 1 to 2 to a
larger extent in the dynamic group. The study was conducted within a university curriculum
for which a mobile learning scenario using portable DVD-players was applied for the first
time. Overall results indicate a high potential for using mobile devices in informal settings
during field trips.
