This article provides pedagogical techniques that require active student participation in the use of computer spreadsheets while determining recursive numerical solutions to equations. Included are several computer screen displays which illustrate the various advantages in using spreadsheets specific to synthetic division, the bisection method,…

Demonstrates how the uniqueness and anonymity of a student's Social Security number can be utilized to create individualized polynomial equations that students can investigate using computers or graphing calculators. Students write reports of their efforts to find and classify all real roots of their equation. (MDH)

A proposition that 3-D CAD provides an array of unambiguous solutions to engineering problems is illustrated. This proposition assumes that engineering problems are conceived in parallel processing mode while they are solved in sequential processing mode. Circle construction analysis, parallel equidistant planes, and solid modeling are discussed.…

An approach to reduce the barrier between two-dimensional computer-aided drafting and three-dimensional constructive solids modeling is graphically illustrated. This process, or some derivative, encompasses a significant portion of the future direction for engineering graphics education. (KR)

Described is a pilot course which includes a designed set of exercises to instruct students in procedures for creating solid models. A detailed description and analysis of students' various approaches used in completing a final design project are included. (KR)

This article describes a calculus lesson that illustrates the nature of cycles in simple systems of nonlinear differential equations through the use of the Lotka-Volterra predator-prey model as incorporated in the computer software package, Phaser (version 1.0). (JJK)

This study described ways that sixth grade students invented strategies for working out difficult physics problems while using a motion program in the computer environment "Boxer." Strategies became a communal classroom resource and ground rules for their use were negotiated with the teacher. (MDH)

Describes the Knowledge Gateway Project at Wenatchee (Washington) High School, which combines computer technology with a problem-solving approach to teach communication and information processing skills to at-risk students. Networked Macintosh workstations are described; and the use of electronic mail to communicate both within a local area…

The problem-solving behaviors and genetics concepts employed by experts and novices during interaction with the computer simulation CATLAB, were examined. Thirteen subjects (3 experts and 10 novices) investigated a common hypothesis on a specific genetic trait during the computer activity. Using naturalistic research methods, general patterns of…

Describes a speech-interactive graphics microworld in which learners speak problem-solving directions to an animated agent and in which new scenarios can be authored. A proof-of-concept application is illustrated for sustaining basic speaking skill in Modern Standard Arabic. (Author/VWL)

Examines mathematics problem solving in a computer software environment using graphical representations of the results of simulations with adolescent students. Discusses the strengths and limitations of inferring goals and plans, the use of verbal protocols, and ways for computer-based learning environments to scaffold acquisition of domain…

Describes three experiments that examined college students' self-determination, problem-solving, and reading comprehension when using a linear, navigational, or generative computerized system to solve a problem or to prepare for a reading-comprehension test. Suggests that understanding students' goals explains outcomes of instruction, effects of…

Examines the importance of the instructional systems design (ISD) model in designing the presentation and content of technology-based learning (TBL) environments, especially for adult learners. Describes TBLs and their use in university and adult learning and discusses the most common presentation methods: drill and practice, tutorial, simulation,…

Reports on a pilot study that examined use by sixth-grade students in Costa Rica of a mathematical microworld written in LOGO. The investigation had three phases: (1) open exploration of the microworld; (2) group discussion and sharing of hypotheses; and (3) guided discovery and problem solving. (Contains 11 references.) (SLW)

Discussion of synchronous computer mediated communications over the Internet focuses on the opportunities and pitfalls of using graphical chat programs in education. Topics include two-dimensional and three-dimensional chat programs; distance education; problem solving groups; exploring cultural differences; language skill development;…
