Spatial-Temporal (ST) Math is game-based
instructional software designed to boost mathematics comprehension and
proficiency through visual learning. Students apply maths concepts to
help a virtual penguin overcome obstacles.
A WestEd evaluation of ST Math
looked at 219 second to fifth grade students (Key Stage 2) in 129
schools that used the game for one year. The students demonstrated a
6.3% gain or better on the California Standards Test (CST) compared to
matched students at similar schools that did not use the program.
The evaluation used a matched-comparison (a
quasi-experimental design alternative to a randomized-control trial).
The authors recognised that the comparison groups may have differed in
ways that were not measured, particularly because the intervention
groups were in schools that elected to implement the ST Math program.
In a separate report,
a large randomized experiment evaluated ST Math in 52 California
elementary schools over a two-year period. In that study, the effect
size on state CST scores averaged only +0.06 and was not statistically
