This What Works Clearinghouse (WWC) report, part of the WWC's Teacher Excellence topic area, explores the effects of the "eMINTS Comprehensive Program," referred to as "eMINTS" in this report, on student achievement. The strong influence of teachers on student outcomes, as well as the variation in teacher effectiveness, has led to the creation of programs designed to help teachers improve their effectiveness in the classroom. The "eMINTS Comprehensive Program" aims to help teachers improve their practice and the outcomes of their students by offering structured professional development, coaching, and support for integrating technology into the classroom. The program's goals include supporting teachers in using classroom technology to implement high-quality, inquiry-based learning, in which students develop understanding and knowledge of content matter by engaging in meaningful investigations that require reasoning, judgement, and decision making. The WWC identified eight studies of "eMINTS." Two of these studies meet WWC standards. The evidence presented in this report is from two studies of the impact of "eMINTS" on students in grades 4, 5, 7, and 8. [For the Intervention Report, see ED604118.
