We estimate relative achievement effects of the four most commonly adopted elementary mathematics textbooks in the fall of 2008 and fall of 2009 in California. Our findings indicate that one book, Houghton Mifflin's "California Math," is more effective than the other three, raising student achievement by 0.05 to 0.08 student-level…

Since 2004, the National Institute for School Leadership (NISL) has offered the Executive Development Program (EDP), a leadership program for sitting school principals that is typically delivered in two-day workshops once per month over 12 months. From its inception through 2018, 15,000 principals across 23 states have participated in the EDP.…

Social engagement by children with autism spectrum disorder (ASD) in unstructured school settings generally occurs at very low levels, if at all. Although many interventions improve peer socialization, generalization and maintenance of such gains when interventions are faded are typically low. The present study employed a multiple baseline design…

School leadership has been shown to exert a positive but mostly indirect influence on school and student outcomes. Currently, there is great interest in how quality leadership preparation is related to leadership practice and improved teacher outcomes. The purpose of the study was to understand the moderating influence of leadership preparation on…

A Mandarin/English two-way immersion elementary program is described from its inception and implementation through the fifth grade, the culminating year of the program. All students in all grades were assessed on their oral/listening, reading, and writing performance in Mandarin using program-created assessment measures. Fifth-grade students also…

A yearlong experimental study showed positive effects of a professional development project that involved 19 urban elementary schools, 180 teachers, and 3735 students from one of the lowest performing school districts in California. Algebraic reasoning as generalized arithmetic and the study of relations was used as the centerpiece for work with…

The authors conducted a quasi-experimental investigation of effects on achievement by grade-level teams focused on improving learning. For 2 years (Phase 1), principals-only training was provided. During the final 3 years (Phase 2), school-based training was provided for principals and teacher leaders on stabilizing team settings and using…

This paper presents a curriculum, textbook and test result analysis for the new (to California) elementary school "Key Standard" mathematics curriculum, transplanted in 1998 from it's foreign roots in Asia and Europe, locations with far different cultural and economic backgrounds. Based on topic analysis methods developed by Michigan…

This study involves the collaboration of researchers with 24 teachers in a 3-year intervention study aimed at investigating and improving vocabulary knowledge and reading comprehension of fourth and fifth grade students for whom English is a second language. Cross-sectional and longitudinal data were collected on various aspects of vocabulary…
