Exploring ST Math’s Implementation and Impact Exploring ST Math’s Implementation and Impact: Technical Appendix

Proving Ground worked with 13 school systems across the country to assess the impact and implementation of ST Math, a mathematics educational software program. We found that students who increased their average weekly usage of ST Math from fall to spring experienced higher math test score gains than students whose usage remained the same.These gains were highest for students with lower baseline usage. Across sites, students used ST Math less than the vendor’s recommended amount, though there was considerable variation within each site. Teachers and schools were responsible for most of this variation.
