Owing to the presence of the Coriolis effect, the rotation of Earth has a multitude of surprising consequences that make the mechanics of the atmosphere or the oceans different from that of a fluid in a container. Since the Coriolis effect also captures the imagination of screenwriters, contributing to the continual exposure of students to bogus…

Earthbound manifestations of gravity in falling objects are distorted by the large mass and size of the Earth. Movement is also affected by air resistance. This article questions whether an approach based on everyday observations is necessarily the best starting point for introducing the idea of Newtonian gravity. Instead, a theoretical approach…

An immense body of literature on astronomy studies has provided evidence that individuals perceive the lunar phases concept as difficult. Furthermore, many studies have shown erroneous explanations or alternative conceptions of lunar phases. However, there is also a need to understand how individuals construct an explanation of the Moon's phases.…

In this paper we discuss the role of transduction in the teaching and learning of science. We video-filmed pairs of upper-secondary physics students working with a laboratory task designed to encourage transduction (Bezemer & Kress, 2008). The students were simply instructed to use a hand-held electronic measurement device (IOLab) to find the…

'Best Evidence Science Teaching' (BEST) is a collection of open-access, research-evidence-informed resources for science teaching at 11-14. BEST includes progression toolkits comprising sequenced learning steps, diagnostic questions and response activities. Case studies illustrate how teachers are using BEST resources. Observations and interview…

We investigated the effect of modeling and visualization resources on upper-division, undergraduate and graduate students' performance on an open-ended assessment of their understanding of physical hydrology. The students were enrolled in one of five sections of a physical hydrology course. In two of the sections, students completed homework…

The purpose of this study is to explore children's typically-perceived-situations (TPS) of "floating" and "sinking". TPS refers to the situation rising spontaneously in an individual's mind when they first think of a phenomenon or concept. Data were collected from 148 Year 5 Korean children. As a result of analysing the data…

Several examples illustrate the human tendency to underestimate the degree of uncertainty present in any theory about the nature of the world. The fallibility of conclusions must always be recognized by the researcher, who must continually challenge assumptions and rethink beliefs. (SLD)

Details the use of tabletop models that demonstrate concepts in direct current electrical resistivity, self-potential, and electromagnetic geophysical models. Explains how data profiles of the models are obtained. (DDR)

Describes an educational program that asks students to attempt to prove that the earth is spherical and that it rotates. Presents tips to pique student interest and charts related to sensing the spin, nonrotation notions, flat earth fallacies, evidence that the earth is spherical and rotates, and the role of watersheds in proving that the earth…

Designed for instruction of emotionally handicapped children and youth, this resource guide presents science activities and concepts relative to rural and urban outdoor education. Included are 25 different articles, varying from broadly generalized to highly specific concept/activity suggestions which include film and book bibliographies and…
