Presents the computer microworlds developed by the Children's Construction of Rational Numbers of Arithmetic (Fractions) Project. Provides an overview of three microworlds: Toys; Sticks; and Candybars. Discusses how children are expected to use the microworlds to construct an understanding of rational numbers. (MDH)

Discusses the nature of misconceptions in science and the role of teachers and students in correcting these misconceptions. Also describes a simulation program that centers on some basic topics in Newtonian mechanics, outlining its structure and examining some of the premises that served as guidelines in its design. (JN)

Uses of Intermedia, computer software designed to help instructors express relationships between concepts in the sciences and humanities, are discussed. The kinds of educational problems Intermedia was intended to address are described, some materials created using it are surveyed, and experiences with Intermedia in various educational contexts…

The computer packages of PLOTALL, SYMAP, SURFACE II, QUSMO, QUSMO2, QUCRS, and QUTAB are commercially available plotting programs that provide aids for visualizing spatial distributed data and concepts. The incremental drum and line printer plots communicate often vast and difficult-to-interpret tabular data with or without geographic coordinates.…

Examples of relatively novel computer software environments from the representation perspective are described. Even more novel approaches to curriculum reform to cultivate higher-order thinking skills are then discussed. (MNS)

Described is the use of computer software, with and without guiding text, for a simulation that presents processes related to electric charges and electric forces underlying the electric-pendulum phenomenon. Included are methods for integrating this simulation with actual middle-school science class demonstration. (JJK)

Defines cognitive computer tools as software programs that use the control capabilities of computers to amplify, extend, or enhance human cognition; suggests seven ways in which computers can aid learning; and describes the "Learning Tool," a software package for the Apple Macintosh microcomputer that is designed to aid learning of…

Describes program operation, applications, and teacher and student opinions of DELPHI, a computer program used in a wide variety of subjects which allows students and instructors to enter questions anonymously for others to answer. These question-answer pairs are then presented to other students or the instructor for comment or evaluation. (MBR)

This set of information sheets is intended to improve practice in special education through technology, media, and materials. The first information profile introduces NCIP (the National Center to Improve Practice), gives an example of how one special education administrator uses NCIP resources, and offers suggestions for facilitating NCIP…

Many feel that an advantage to using computer simulations in science teaching is that they give students the opportunity to witness or perform experiments which might otherwise be too expensive, time consuming, or dangerous for them to do. Simulations attempt to mimic the kind of experience students get in a laboratory and help students learn new…

Two computer programs were developed to enhance community college students' critical thinking skills in the areas of "Comparison and Contrast" and "Analysis." Instructors have several options in using the programs. With access to an LCD panel and an overhead projector, instructors can use the programs in the classroom, manipulating the computer…
