The present article evaluates a pilot service-learning program for fifth- and seventh-grade (N = 86) children in a large, urban,…

The present study examined the cognitive factors that influence children's physical science learning from a multimedia instruction. Using a causally coherent text and visual models, we taught 4th- and 7th-grade children about the observable and molecular properties of the three states of water. We manipulated whether the text was read by a tutor…

The research on the potential relationship of the Northwest Evaluation Association's Measures of Academic Progress (NWEA MAP) and the Illinois Standards Achievement Test (ISAT) was conducted in two phases and focused on middle schools with a grade configuration of 6-8 in the state of Illinois. The first phase of the research examined whether or…
