This work investigates science major students' misconceptions about "force and motion." Stratified-convenience sampling method has been conducted on 232 Moroccan high school students. Using Force Concept Inventory (FCI), we examined all known misconceptions listed in the original article by Hestenes et al. (1992, "Phys. Teach."…

Previous research indicates children reason in different ways about horizontal motion and motion in fall. At the same time, their understanding of motion down inclines appears to result from an interaction between horizontal and vertical motion understanding. However, this interaction is still poorly understood. Understanding of speed change may…

The present study aimed at investigating children's and adolescents' understanding of constant and accelerated motions. The main objectives were (1) to investigate whether different task formats would affect the performance and (2) to track developmental changes in this domain. Five to 16 year olds (N = 157) predicted the distances of a moving…

Explores whether older students were less ready than younger students to change their alternative conceptions. Findings indicate that after reading a refutational text, conceptual change occurred in 35% of Year 6 students and 44% of Year 10 students. Concludes that there was no evidence to suggest that conceptual change is more difficult for older…

This paper describes life-span development of understanding about pendulum motion and effects of school science. The subjects were 2,766 people ranging from kindergartners up to 88 years senior citizens. The conflict and consensus between children and their parent's understanding of pendulum motion were also analyzed. The kindergartner's…

This article is the first of a two-part review of research on children's and adults understanding of gravity and on how best to teach gravity concepts to students and teachers. This first article concerns free fall--how and why objects fall when they are dropped. The review begins with a brief historical sketch of how these ideas were developed in…

This is the second and final part of a review of educational research on children's ideas about gravity. The first part concerned students' understanding of how and why things fall. This article picks up the trail of research studies that address students' understanding of the more complex ideas of projectile motion and orbits and examines how the…
