Students (n = 1,069) from 60 4th-grade classrooms were taught the control of variables strategy (CVS) for designing experiments. Half of the classrooms were in schools that performed well on a state-mandated test of science achievement, and half were in schools that performed relatively poorly. Three teaching interventions were compared: an…

Elementary science is chock-full of wonderful experiences for students. Do children see iPads as a tool for learning about science? Using Prensky (2010) as a guide, the researchers decided to see if "assessing students with their own" tools (p.178) using iPad apps would support learning discrete knowledge for electricity and light…

Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…
