Teachley Research at a Glance

At Teachley, we take research seriously (it’s in our tagline, after all).  Our products are developed with grant funding from the U.S. Department of Education, Institute of Education Sciences (IES) and the National Science Foundation (NSF). As part of these grants, we conduct ongoing research to evaluate the effectiveness of our apps in improving students’ mathematical abilities.

Design research. When developing our apps, we utilize an iterative design research process during which we build initial prototypes of the app and its features, such as levels and scaffolds, then give them to kids to play. We observe as they interact with the app, ask questions, and gather valuable feedback to inform the refinement of the app.

Efficacy research. To evaluate whether our apps impact learning, we conduct research studies during which we explore changes in students’ abilities before and after they play. To help synthesize some of our research efforts, we’ve put together two short briefs and link to them below.

Teachley Operations. Students who played our operations apps impaddimals-multiplis-ipad-2roved their fluency more than students who played traditional fluency games. Further, students using our Mt. Multiplis app were significantly more likely to use the distributive property when explaining how they solved problems. These results were also found when looking specifically at children who struggle in mathematics. Read the full Teachley Operations brief here.  


Teachley Fractions. Initial research on a prototype of our first fractions app, Fractions Boost found significant effects on students’ ability to estimate fractions on a number line. Read the full Teachley Fractions brief here.
