Because of increased capabilities for collecting and analyzing education data, the field has new opportunities for research-based, data-driven improvements in education activities. However, education practitioners have not been fully able to leverage these developments and data to inform large scale improvements in the field. In this program, trainers will prepare education practitioners to use established and emerging data science methods with an emphasis on statistical thinking and computa...

In this project, researchers will conduct design-based research with students, parents, and teachers to develop a mobile data-optimized tutoring system to promote deliberate math practice for middle-school students, combined with a new system for parent-student motivational nudges to encourage parents to support their children in doing homework. The research team will optimize units from the Mathtutor platform-a comprehensive web-based tutoring system for middle-school mathematics-and specif...

Research within the domains of cognitive science and mathematics education suggests that students develop a better understanding of mathematics concepts and learn more quickly when half of their practice problems are replaced with worked-out example solutions. Learning is further enhanced when students are prompted to provide explanations for key steps in the worked examples. Despite an accumulation of evidence, typical Algebra I textbooks contain few worked-out example solutions and few pro...

The postdoctoral program trained four scientists to do rigorous research on learning conditions related to curriculum, instruction, and assessment for diverse K–12 student populations.

The National Center for Cognition and Mathematics Instruction has a core goal of redesigning components of a widely-used middle school mathematics curriculum-Connected Mathematics Project (CMP), and evaluating the efficacy of the redesigned curriculum materials.

Students and teachers have considerable trouble overcoming misconceptions in algebra. These misconceptions, if not addressed, will have long-term negative consequences for students' mathematics achievement. There is a growing body of research showing that students benefit from instruction that includes incorrect examples. The proposed study will develop a computer program designed to overcome misconceptions through the use of incorrect examples, which will be compared to the use of correct e...
