Abstract: The REDEEM authoring environment allows teachers to create learning
environments from existing computer-based training (CBT) by imposing their
pedagogical preferences about how students should best be taught. We conducted
two studies where classroom teachers constructed learning environments with
REDEEM from pre-existing CBT to explore if this approach is educationally
effective. Using a crossover design, the learning outcomes for 14-16 year old
students who studied Genetics with these environments (either a REDEEM then CBT
course or vice versa) were compared. In the first study, we found that
performance of 74 students improved significantly but was not influenced by
type of environment. Inspection of process data revealed that students who
engaged with REDEEM's features did learn more. In the second study,
conducted in a more natural context, a further 15 students completed the
courses. REDEEM significantly improved learning compared to CBT. Analysis
suggested that REDEEM enhanced performance by supporting additional
interactivity but that macro-adaptation did not appear to impact upon learning.
Possible interpretations of these results are discussed in the light of the
many evaluation issues for authoring tools.
