To help young students succeed in problem-based learning (PBL), researchers suggested investigating students' need for cognition (NFC), one's inclination to exert mental effort during learning. How one puts mental effort into a learning task is related to motivation. If motivated, students are more likely to engage in challenging tasks, put in…

The Chinese proverb "heal a headache by curing the head and heal foot pain by curing the feet" alludes to ineffective work resulting from a lack of covariation in reasoning. Actually, much problem solving relies on the analysis of how two or more factors vary in correlation with another related variant (i.e., covariation reasoning). To…

This study investigated the effects of metaconceptually-enhanced, simulation-based inquiry learning on eighth grade students' conceptual change in science and their development of science epistemic beliefs. Two experimental groups studied the topics of motion and force using the same computer simulations but with different simulation guides: one…

It is critical that students learn how to retrieve useful information in hypermedia environments, a task that is often especially difficult when it comes to image retrieval, as little text feedback is given that allows them to reformulate keywords they need to use. This situation may make students feel disorientated while attempting image…
