Previous work applying cognitive load theory has demonstrated the effect of various text/graphic/narration relations on learning using multimedia material. Other work has looked at how the degree of integration between the text and graphics influences their use. This study set out to look at how the degree of integration between text and graphics…

CADMOS is a graphical learning design (LD) authoring tool that helps a teacher design a unit of learning in two layers: (i) the conceptual layer, which seems like a concept map and contains the learning activities with their associated learning resources and (ii) the flow layer, which contains the orchestration of these activities. One of CADMOS'…

Educational hypertexts usually include graphical overviews, conveying the structure of the text schematically with the aim of fostering comprehension. Despite the claims about their relevance, there is currently no consensus on the impact that hypertext overviews have on the reader's comprehension. In the present paper we have explored how…

The number of experimentally derived structures of cellular components is rapidly expanding, and this phenomenon is accompanied by the development of a new semiotic system for teaching. The infographic approach is shifting from a schematic toward a more realistic representation of cellular components. By realistic we mean artist-prepared or…

Many culturally and linguistically diverse (CLD) students with specific learning disabilities (SLD) struggle with the writing process. Particularly, they have difficulties developing and expanding ideas, organizing and elaborating sentences, and revising and editing their compositions (Graham, Harris, & Larsen, 2001; Myles, 2002). Computer graphic…

Students in higher education today are technologically savvy and expect faculty to use myriad web technologies for course delivery. This includes taking advantage of email, course web sites, and online learning communities. However, expectations now also include RSS, blogs, web-, pod-, and vod-casting, extending the classroom experience to provide…

The document provides an introduction to computer graphics and is intended to be used as reference material to assist the high school drafting student in compiling information. A teletype machine with an acoustical coupler for telephone hookup and a time-sharing Peripherals Corporation flatbed plotter were acquired, and an illustrated programer's…

Describes activities designed to teach students about embedded recursion. Topics cover providing intuitions about embedded recursions, predicting embedded recursions, seeing patterns and processes, presenting graphic designs containing embedded copies of themselves, and exploring graphics, numerical, and word examples. Parts I and II are in…

Reviews Apple-II versions of "CyberLogo Turtle" and "Delta Drawing." Focuses on special features, educational value, design quality, written materials, and ease of use, pointing out strengths and weaknesses. Both programs are given high rankings for criteria reviewed. (JN)

Describes a rapid computer technique for plotting Eh-pH diagrams using a line printer. (MLH)

Described is an inexpensive apparatus, consisting of a microcomputer, a magnetostrictive digitizing tablet, and a teletype terminal, that accurately and quickly measures positions, lengths, and areas. Particular emphasis is given to interfacing, software, and to some applications in education and research of this minimum configuration system.…

A computer program which allows the solution of a Monte Carlo simulation (probabilistic sensitivity analysis) has been developed for the Vic-20 microcomputer. Theory of Monte Carlo simulation, program capabilities and operation, and sample calculations are discussed. Student comments on the program are included. (JN)

In order for microcomputers to be used in an efficient and effective manner in the classroom, the computer should not be used in trivial ways, such as utilizing it as an electronic ditto sheet or as a video textbook. Educators must take advantage of the computer's unique capabilities, including its branching capacity, its graphic mode, and its…

Describes interactive, geology programs (GEOPACK) for use in geostatistical applications, demonstrations and reviews, and geocartography. Programs, designed for beginning and advanced students, make use of the graphics capabilities of the Apple II microcomputer. (JN)

The third in a series of reports on the educational applications of computers. Focuses on ERIC materials that can help educators learn more about the graphic capabilities of CRTs. (FL)
