For more than 150 years, printers have been faithfully reproducing continuous tone originals using halftoning techniques. For about 120 years, printers could only use the AM halftoning technique invented by Henry Talbot. In recent years, the advent of powerful raster image processors and high-resolution output devices has increased the variety of…

This paper addresses the views of students of blended language learning (BLL)--a particular learning and teaching environment, that combines face-to-face (f2f) and computer-assisted language learning (CALL). In this instance, the "blend" consisted of learners' independent self-study phases at a computer, with a CD-ROM, and traditional f2f…

In Taiwan, lectures are commonly used for younger students to learn their own language, which is traditional Chinese. Passively listening to lectures has led to this group of students making such mistakes as forgetting strokes and word meanings, combining phrases to create incomprehensible blurs of information, and switching radicals with phonetic…

This brief paper describes several computing tools that have been effectively used by individuals with mobility impairments. Emphasis is on tasks to be completed and how the individuals abilities (not disabilities), with possible assistance from technology, can be used to accomplish them. Preliminary information addresses the importance of…

Data from three projects (a CD-ROM of the periodic table, video animation on CD ROM, and data loggers) show how conditioned dispositions affect information/communications technology use. The projects demonstrate how students have been conditioned to work mindlessly in science classrooms, following the path of least cognitive demand and avoiding…

Discussion of development and management of a CD-ROM workstation for library reference services covers: (1) IBM compatibles; (2) computer storage capacity; (3) compact disk drives and printers; (4) file management; (5) protecting the integrity of a hard disk; and (6) backing up software. (three references) (MES)

Discusses using high-speed modems to access the Internet. Examines internal and external modems, data speeds, compression and error reduction, faxing and voice capabilities, and software features. Considers ISDN (Integrated Services Digital Network) as the future replacement of high-speed modems. Sidebars present high-speed modem product…

Describes a low-cost, upgradeable, CD-ROM network and gives a step-by-step description of the installation process, including inventorying assets, learning about network components, selecting a network, installing adapter boards, attaching cabling, installing software, testing, configuring the server, installing search software, installing a menu,…

Discusses the process and demonstrates the utility of repackaging lantern slides (i.e., photographs printed on glass or film sandwiched between glass) as digital images. A prototype community memory interface for access to the images is described, and photographs of the visual index to stored images are included. (seven references) (KRN)

Discusses the use of portable keyboards that can download their information into a computer and describes how they can be used effectively in elementary school classrooms. Highlights include uses in various subject areas, including writing improvement; student motivation; taking keyboards home; and uses outside the classroom, including field…

Suggests school leaders must understand the total cost of ownership (TOC)-all of the costs involved with installing, operating, and maintaining computers-if they are going to use them to full advantage and cost-effectively. Discusses the major components of TCO after initial hardware investment (professional development, software, support, and…

Evaluates outSPOKEN, a Windows 95 screen reader for people with visual disabilities. Evaluates the program for installation and documentation (good), Word 97 (good), WordPerfect 8.0 (less than good), and Internet Explorer and Navigator (a little less than good). Provides specific suggestions for improving performance and steps for selecting a…

Colour is a common feature in computer-aided learning (CAL), though the instructional effects of screen colour are not well understood. This investigation considers the effects of different CAL study tasks with feedback on posttest performance and on posttest memory of the lesson colour scheme. Graduate students (n=68) completed a computer-based…

BusinessThinking [TM] is a computer-based e-learning package designed to teach technology skills and business information to adults, ages 50-69, who remain in the workforce. This article outlines results from usability testing for the material on using technology applications (Microsoft Word, PowerPoint, Excel and the Internet), and career…

OsmoBeaker is a CD-ROM designed to enhance the learning of diffusion and osmosis by presenting interactive experimentation to the student. The software provides several computer simulations that take the student through different scenarios with cells, having different concentrations of solutes in them.
