The purpose of this research was to explore how adult users interact and learn during an interactive computer-based simulation supplemented with brief multimedia explanations of the content. A total of 52 college students interacted with a computer-based simulation of Newton's laws of motion in which they had control over the motion of a simple…

A schema based view of addition development is compared with Siegler's latest strategy-choice model, which includes an addition goal sketch (a basic understanding of "the goals and causal relations" of addition; Siegler & Crowley, 1994, p. 196). This metacognitive component in the latter model is presumed to develop as a child practices a basic…

Selections of liquid aldehydes and ketones are proposed for students to determine what property is the best predictor of the color (yellow to red) of their 2,4-dinitrophenylhydrazone derivative. Students may use a computer (spreadsheet or word processor) to analyze results. (Contains 1 table and 3 notes.)

In this study, a desktop virtual reality earth motion system (DVREMS) is designed and developed to be applied in the classroom. The system is implemented to assist elementary school students to clarify earth motion concepts using virtual reality principles. A study was conducted to observe the influences of the proposed system in learning.…

Children possess a genuine curiosity for exploring the natural world around them. One third grade teacher capitalized on this inherent trait by leading her students on "A Geometric Scavenger Hunt." The four-lesson inquiry investigation described in this article integrates mathematics and science. Among the students' discoveries was the fact that…

This booklet can help college instructors breathe life into sociology classes by showing students how sociology is "done" in the real world. Twenty-nine exercises demonstrate to students how data are collected, how data are used to support or refute ideas, how data are interpreted, and the questions raised by different methods of research. The…

This article is a commentary on TM 501 927 by the authors of the study "Classification and Seriation Instruction and Logical Task Performance in Preschool." (DEP)

This article shows how two discoverable theorems from elementary calculus can be presented to students in a manner that assists them in making the generalizations themselves. The theorems are the mean value theorems for derivatives and for integrals. A conjecture is suggested by pictures and then refined. (Author/KM)

In a study comparing the acquisition of information and the understanding of significant concepts by 5th grade children who studied science from two different approaches, the results lent support to the belief that science programs which allow students to discover solutions for themselves are more effective than a content-oriented approach.

Suggests using food as a resource for the discovery and experimental methods of learning with preschoolers. (BR)

The middle school is a bridge between elementary and secondary schooling that helps students pass from childhood to adolescence. Within the middle school is another bridge--the exploratory/elective program. Whereas the core curriculum focuses on students' academic development and the cocurricular program on their equally important personal and…
