We participated in data collection, field visits and a variety of analyses of existing data in 2014-15 to understand the GRS program context and to identify drop-off and related sticking points in the GRS program design. During the 2015-2016 school year, we rolled out a series of quick turn-around interventions including strategies to boost enrollment at the GRS orientation sessions in October of 2015. We then introduced a host of BE-infused materials and text messages to facilitate parent-teacher communication about GRS activities in November. For the 2016-2017 school year, we designed a personalized feedback letter informing parents about the time they reported spending on GRS activities; and, creating a series of supplemental messages and images to encourage use of math activities at home. Stay tuned! Our paper is currently under review.
