Seperuelo Duarte, E.; Mota, A. T.; de Carvalho, J. R.; Xavier, R. C.; Souza, P. V. S. – Physics Education, 2021
In this paper, we present a physical modeling activity whose objective is to allow students to determine the differences between a disk and a sphere using pure scientific criteria. Thereunto, we reproduce the Sun-Earth-Moon system with low-cost materials and compare the illumination effects on the Moon considering two possible shapes for it (a…

Celikten, Oksan; Ipekcioglu, Sevgi; Ertepinar, Hamide; Geban, Omer – Science Education International, 2012
The purpose of this study was to compare the effectiveness of the conceptual change oriented instruction through cooperative learning (CCICL) and traditional science instruction (TI) on 4th grade students' understanding of earth and sky concepts and their attitudes toward earth and sky concepts. In this study, 56 fourth grade students from the…

Cherif, Abour H.; Adams, Gerald E.; Morabito, David; Aron, Robert; Dunning, Jeremy; Gialamas, Stefanos – Science Education Review, 2010
The recent missions to Mars have produced a mass of data and information in all forms and have forced the minds of many people world-wide to rethink their own perspectives on life itself. This drama unfolding about 35 million miles from Earth, and digitally on our TV screens, is offering a growing reservoir for teachable moments. The curiosity and…

Werts, Scott; Hinnov, Linda – Journal of Geoscience Education, 2011
We present a MATLAB script INSOLATE.m that calculates insolation at the top of the atmosphere and the total amount of daylight during the year (and other quantities) with respect to geographic latitude and Earth's obliquity (axial tilt). The script output displays insolation values for an entire year on a three-dimensional graph. This tool…

Chiras, Andreas – Science Education International, 2008
The study investigated the mental models of primary school children related to the day/night cycle. Semi-structure interviews were conducted with 40 fourth-grade and 40 sixth-grade children. Qualitative and quantitative analysis of the data indicated that the majority of the children were classified as having geocentric models. The results also…

Agan, Lori – Astronomy Education Review, 2004
In this study, high school and first-year undergraduate students were asked about their understanding of stars. The hypothesis guiding this research posits that high school students who have taken a semester-long astronomy course will have an understanding of stars most related to scientific knowledge, compared with high school students enrolled…
