This report is about how a group of U.S. teachers (N = 98) and researchers used a boundary object in a collective study of grades 6-8 mathematics instruction. The focus is the teachers' engagement with a framework for effective instructional practices. Using qualitative content analysis of teachers' responses to use of the framework, we assessed…

When teachers engage in forms of science teaching that disrupt the status quo of typical school science practices, they often experience dilemmas as problems of practice that are difficult--or even impossible--to solve. This instrumental case study examines one teacher's efforts to teach science for equity across two contexts: a public middle…

Student voice is recently attracting educational researchers' attention for its influence on various aspects of student lives and futures, as well as social life in general. Mobile technologies are proliferating in social and practical life. This article studies student voice in carrying out outdoor activities with mobile phones. Thirty middle…

This report contains resources to help researchers and policymakers review measures used in NCEE evaluations of educational interventions. The measures included in the Compendium are applicable to settings for preschool through grade 12. The Compendium discusses criteria and their importance in selecting measures for assessing intervention impacts…

Middle school teachers' use of digital curricula incorporating dynamic technology has been found to support student learning of complex algebraic concepts. This article reports on pilot research involving collaboration among faculty from a public university's college of education, educational researchers from a nonprofit research organization, and…

The Aplusix system has been designed for helping students to learn algebra. Its capacity to tell the students whether their calculations are correct or not, to provide families of exercises of a chosen level, and to give scores after tests allows this system to be used in the regular functioning of the class. Its capacity to record the students'…

A science teacher and her mentor reflect on their participation in the Learning Research Cycle, a professional learning model that bridges research and practice in both university and public school contexts. Teachers do scientific research in scientists' laboratories, then bridge their scientific experiences with the design of new classroom…
