The focus on STEM has centered on knowledge use across multiple disciplines. However, there currently exists limited understanding of the relationship between the cognitive practices utilized across these disciplines as a function of performance on standardized assessments. Focusing on science and mathematics, we investigated the direct and…

Various inquiry approaches have been promoted in science classrooms as a way for students to engage in, and have a deeper understanding of scientific discourse. However, there is a paucity of empirical evidence to suggest how children's actions and engagement in these approaches, or "practical epistemologies" (Sandoval, Science Education…

Students with special needs tend to show significantly lower achievement in science than their peers. Reasons for this include severe difficulties with academic skills (i.e. reading, math and writing), behaviour problems and limited prior understanding of core concepts background knowledge. Despite this bleak picture, much is known on how to…

This quasi-experimental and pre/posttest study was designed to examine whether fourth-grade students who engaged in collaboratively writing letters to 11th-grade students performed better on tests of conceptual understanding of a unit on force and motion than students who did not. The participants included 835 fourth-grade students and 416…

The purpose of this study was to identify and describe teaching actions--embedded in the "Science Writing Heuristic approach," a systematic teaching approach that integrates literacy instruction and argument-based inquiry learning of science--supportive of the cross-disciplinary literacy expectations necessary to compete in the 21st…
