Discusses the availability of full-text periodical archives on the World Wide Web. Highlights include digitized photographs and other images, in addition to text, costs, the use of search engines, and a list of Web sites. (LRW)

Describes and evaluates two USEPA shareware programs called Principles of On-Site Wastewater Treatment (ONSITE) and Residential Waste Treatment Evaluation (RWASTE). ONSITE, a tutorial, provides an overview of septic systems and their relationship to soils. RWASTE builds on ONSITE. Both are effective tools for persons interested in acquiring…

Presents accumulated insights for benefit of colleagues considering embarking on software development projects. Original purpose of project was to produce a set of grammar revision and extension modules allowing teachers to use computers as a means of ensuring that once a language point had been dealt with in class, students could be required to…

Discusses the use of digital cameras in elementary and secondary education. Highlights include hardware and software; applications; practical considerations, including cost; curriculum possibilities; examples of activities for elementary, middle, and high schools; and using cameras for student assessment and for administrative support.

Describes several exemplars of software that emulate and incorporate machine-supported aspects of cognitive apprenticeships in science and mathematics. Concludes with an evaluation of software against cognitively guided principles and with a summary of the difficulties associated with creating and implementing machine-supported apprenticeships.…

Describes a parser-driven Japanese tutor, "BANZAI," designed for second-language instruction and presents an empirical study of the program. Results indicate that ongoing rule-driven deductive feedback is more effective than example-driven inductive feedback for learning relatively complex structures whose grammatical rules are not…

To prevent vastly different Internet access policies from creating uneven service for patrons from community to community, the author argues that librarians, as the logical champions, must define "universal service." Offers hardware, software, Internet functions, training, and service as some of the elements of access that should be…

Discusses the benefits of school library security, software security, and computer security systems. Describes specific products for each type of security system. A sidebar lists names and addresses of security manufacturers and distributors. (AEF)

Scenario refers to specific courses of action/events occurring within computer simulations and attempting to recreate lifelike situations. This article identifies critical features and their elements in designing effective scenarios in computer-based instructional simulations: (1) sequence; (2) operating procedures; (3) characteristics of…

Describes how students in a 10th-grade geometry class discovered relationships that led to the development of conjectures, theorems, and directions of proofs regarding the centroid of a triangle. (ASK)

Presents an activity on the sum of the measures of the interior angles of a five-pointed star by using The Geometer's Sketchpad. (ASK)

Discusses six principles of visual perception and their cognitive implications for interactive screen design: clear perception determines continuity and flow of information; perceptual grouping establishes screen sequencing; placement of information aids recall; distinctiveness increases retention and retrieval; consistency in the perception of…

Discusses the application of computer based training (CBT) to human-computer interface design. Describes course considerations; courseware; and software environment for practice, and presents a case study outlining small group production of interactive guidebooks. Concludes that CBT can reduce instructional time and is an effective method for…

Argues that there is a need for more research on the effectiveness of instructional methods in developmental education, but acknowledges that standard experimental procedures are not appropriate for developmental classrooms. Describes Simulation Implementations of Peripatetic Learning Environments (SIMPLE), a computer-based tool for creating…
