Objectives of this study were to create a prototype of an interactive hypermedia textbook and to explore the relationships between learners' performance and use of available learning tools (i.e., textbook glossary and navigation map). The effects of prior knowledge on textbook use and performance were also investigated. (11 references) (EA)

Studies the simple dynamical system of the pendulum and the chaotic behavior that occurs when the pendulum is both damped and driven. Provides an algorithm and BASIC program for the numerical solution to the differential equations encountered in the discussion. (MDH)

Using a custom-designed hypercard program, 26 University of Iowa students collaborated to create an interpreter's annotated edition of "Paradise Lost." Successful use of these technical resources required teachers to consider student computer skills, specific learning tasks, social dynamics of collaborative, creative work, and ways to…

Describes the ScrapBookUSA Writing Project, a computer telecommunications project linking classrooms across the country, and its educational opportunities for the writing and multicultural studies curricula. Examples of Hello letters, student essays, and ScrapBook Chronicles are given to demonstrate the impact a wide audience and immediate…

Learning environment that facilitated the acquisition and expression of procedural skills in LOGO was set up for children in the 10- to 12-year range. Ten participants were placed in a series of situations that required them to manipulate programing procedures in LOGO. Analysis of children's behavior revealed their competence in manipulating…

An attempt was made to improve the argumentation skills and scientific thinking skills of 24 Swedish college students through argumentative on-line (computer-mediated) studying. Comparison with about 200 students studying in traditional ways reveals better learning outcomes for the traditional group but better argumentation by the on-line group.…

Discusses the portability of computer-related media in international distance education. Factors that influence portability of educational media are considered, current and potential applications in both developed and developing countries are described, and strategies to plan for portability are suggested that include political, social, and…

Described is a mathematics resource laboratory where students use a variety of computer materials to enhance, reinforce, and broaden their concepts of first- and second-year algebra and geometry. Included are sample laboratory sheets and the answers. (KR)

The existing methods for graphically illustrating projection and coordinate systems for manual and computer-aided drafting and design are examined. Inconsistencies in methods used to graphically depict first and third angle projection in texts and the lack of attention in the relationship of projection to coordinate systems are noted. (KR)

An algorithm is described for generating smooth curves of first-order continuity. The algorithm is composed of several cubic Bezier curves joined together at the user defined control points. Introduced is a tension control parameter which can be set thus providing additional flexibility in the design of free-form curves. (KR)

The focus of this article is on how computer graphics can be integrated throughout the engineering graphics curriculum to increase visual perceptual skills. Visual perception is defined, the need to develop it is described, and methods which engineering graphics educators can use to develop it are outlined. (KR)

Described is a take-home project in which students use an electronic systems kit to produce a working circuit. Students were asked to identify a security need in their own home and design and build a suitable security system. The use of a computer to produce the circuits is advised. (KR)

This field study represents a departure from structured, or directed, computer-mediated communication as used in its natural environment, the computer lab. Using observations, interviews, and the computer medium itself, the investigators report how high school students interact with computers and create their own agendas for computer usage and…

This review features new examples of using the computer relative to college-level mathematics to enhance pedagogy, solve problems, and model real-life situations. Included is a LOGO program that can be used to create and to stimulate subsequent investigations of spirolaterals, those figures generated by repeatedly drawing basic loops. (JJK)

A computerized presentation explaining how to use the library online catalog (NOTIS) was produced at Texas A&M University. A study using students in first-year composition courses verified that students who viewed the presentation were able to use the online catalog more effectively than those who did not, especially for subject searching. (12…
