The theory that children's development of strategies-of-science experimentation is a consequence of developments in theory of mind was examined with 72 children in grades one, three, and five. Ability to predict, explain, and affect the reasoning of a doll or cartoon character predicted performance in planning controlled experiments and in…

Describes an ammeter that can be built for less than a dollar with commonly available parts to be used in circuits with 3-volt light bulbs. (WRM)

Describes the development, preparation, and use of a medium that can select against a wide variety of Gram-negative bacteria while still allowing growth and differentiation of a wide range of Gram-positives. (WRM)

Describes a simple, inexpensive modification that changes a brightfield microscope into a darkfield microscope, allowing low-contrast samples to be examined. (WRM)

Describes the construction and use of an inexpensive, portable photometer designed specifically for estimating population sizes in yeast cultures. Suggests activities for use with the photometer. (WRM)

Describes a short undergraduate course built entirely around a research trip to an astronomical observatory. (WRM)

Describes a review of research that addresses the effectiveness of simulations in promoting scientific discovery learning and the problems that learners may encounter when using discovery learning. (WRM)

The intent of this study was to investigate the impact of introducing computerized means, mainly simulation and the Internet, on teaching and learning electronics in Israeli high schools. Computers in electronics studies are, at the same time, part of the subject matter learned and a means for teaching and learning. Data were collected through…

Although much contemporary thinking leads to the expectation that communication technology, such as video streaming, enhances educational performance on the average, a dearth of strong evidence consistent or inconsistent with this claim precludes a thoughtful evaluation of it. A series of experiments designed to examine this proposition…

Imagine a science activity that excites native English speakers and English learners alike while simultaneously teaching students about tools used in science experiments, increasing science vocabulary, and improving students' skills in recording information. Inventorying science kits or materials from science units with students does just that…

An infrared (IR) thermometer lab offers the opportunity to give science students a chance to measure surface temperatures, utilizing off-the-shelf technology. Potential areas of study include astronomy (exoplanets), electromagnetic spectrum, chemistry, evaporation rates, anatomy, crystal formation, and water or liquids. This article presents one…

In this article, the author talks about an inquiry-based activity involving yeast, wherein students learned about cell size. The activity allows students to employ math connections and to learn experimental techniques while practicing microscope skills. The activity can be adapted for students at all levels of biology. The author presents details…

I describe and evaluate SuperLab LT (Chase & Abboud, 1990), a software package that enables students to replicate classic experiments in cognitive psychology. I also discuss the package with respect to its uses in teaching an undergraduate course in Experimental Psychology. Although the package has minor flaws, SuperLab LT provides numerous…

Students encounter many obstacles during scientific discovery learning with computer-based simulations. It is hypothesized that an effective type of support, that does not interfere with the scientific discovery learning process, should be delivered on a "just-in-time" base. This study explores the effect of facilitating access to…

Based on a questionnaire to academic staff, this article examines the reading and writing tasks assigned to undergraduate science students at a South African university. The article finds that although academic staff in science value clearly written and well-organised writing, few see it as their task to induct students into this literacy. Instead…
