Students often need support to optimize their learning in inquiry learning environments. In 2 studies, we investigated the effects of adding concept-map-based support to a simulation-based inquiry environment on kinematics. The concept map displayed the main domain concepts and their relations, while dynamic color coding of the concepts displayed…

The purpose of this study was to assess the effectiveness of an intervention designed to foster epistemic change over the course of 1 semester. The intervention was based on constructivist teaching practices that incorporated teacher modeling of critical thinking of content, evaluation of multiple approaches to solving problems, and making…

Thirty-two factual statements, half consistent and half not consistent with subjects' prior knowledge, were processed by 140 sixth and seventh graders. Half were directed to use elaborative interrogation (using prior knowledge) to answer why each statement was true. Across all memory measures, elaborative interrogation subjects performed better…

Effects of 2 types of oral language training programs on development of phonological awareness skills and word learning ability were examined for 48 kindergartners. Children receiving analytic and synthetic training improved significantly on both types of skills, but children receiving synthetic skills training alone improved only in blending…

Within-class experimental designs are subject to diffusion effects whereby both experimental and control students benefit from the intervention, thereby contaminating the control group and biasing evaluations of intervention effects. In support of diffusion effects, this study showed that a classroom intervention resulted in higher academic…

The development of the associative structure of physics concepts as a result of the content presented to the learner and the relationship between associative structure and academic achievement was investigated using a treatment and a control group. Assessment of associative structure may allow insight into a learner's progress which complements…

The role of elaborative interrogation in children's learning of facts was investigated in 2 experiments involving 211 female and 185 male Canadian fourth through eighth graders. When compared to the facts alone, precise elaborations given by the experimenter, or learner-constructed imagery, elaborative interrogation produced better learning in…
