Background: Problem-based learning (PBL) is a teaching approach working in cooperation with self-learning and involving research to solve real problems. The first law of thermodynamics states that energy can neither be created nor destroyed, but that energy is conserved. Students had difficulty learning or misconceptions about this law. This study…

Conceptual change instruction recognizes that students bring personal, or naive, conceptions to the classroom, which they use to explain their world, interpret situations, and create meaning (Driver et al. 2007). But what happens when students' personal conceptions are inconsistent with experts' views of scientific knowledge? Even after direct…

Presents some additional comments from the current author regarding his original article "Filling-in models of completion: Rejoinder to Kellman, Garrigan, Shipley, and Keane (2007) and Albert (2007)." Despite repeated assertions by Kellman et al., I have never claimed that luminance constraints block modal completion; rather, they merely weaken…

The consistent, but often wrong, impressions people form of the size of unseen speakers are not random but rather point to a consistent misattribution bias, one that the advertising, broadcasting, and entertainment industries also routinely exploit. The authors report 3 experiments examining the perceptual basis of this bias. The results indicate…

In our comment on Wixted, we argued that most of the concerns he initially raised reflect misconceptions about the dual-process signal-detection (DPSD) model's underlying assumptions (e.g., threshold recollection can, in fact, be graded, and no task or population is expected to provide process-pure measures). Wixted's response does not directly…

This paper presents results of an empirical research study on Newton's laws classical mechanics and its perceptions on freshman students at the Physics Department, University of Ioannina, Greece. Results and outcome measures reveal misconceptions on students' perceptions in consideration of the fundamental concepts in freshman Physics education.…

"Multitasking" has developed a certain mantra in our culture, and according to this widely held axiom, people in general and students in particular, can and do function productively and learn efficiently doing several things at once.

Over the past three decades, the literature in science education has accumulated a tremendous amount of research on students' conceptions--one bibliography currently lists 7000 entries concerning students' and teachers' conceptions and science education. Yet despite all of this research and all the advances in the associated conceptual change…
