This intermediate session demonstrated how we conducted an a priori power analysis for a longitudinal,multisite cluster randomized trial of an early childhood science education program, then later revised it to accommodate budget changes suggested by the funder without compromising the viability of the study.

The goal of this study is to assess the educational, career, and social impacts of disseminating an innovative technology, the XO laptop computer, to minority 4th and 5th grade students in Birmingham City Schools (BCS) in Alabama. This is the largest XO dissemination in the U.S. and the first XO dissemination project to distribute XO laptops to all 1st – 5th grade students in a U.S. school district.

Measurement is a critical component of mathematics education, but research on the learning and teaching of measurement is limited, especially compared to topics such as number and operations. To contribute to the establishment of a research base for instruction in measurement, we evaluated and refined a previously developed learning trajectory in early length measurement, focusing on the developmental progressions that provide cognitive accounts of the development of children’s strategic and conceptual knowledge of measure. Findings generally supported the developmental progression, in that children reliably moved through the levels of thinking in that progression. For example, they passed through a level in which they measured length by placing multiple units or attempting to iterate a unit, sometimes leaving gaps between units. However, findings also suggested several refinements to the developmental progression, including the nature and placement of indirect length comparison in the developmental progression and the role of vocabulary, which was an important facilitator of learning for some, but not all, children.
