This paper discusses a computerized learning environment called TurtleGraph that is designed and developed to support collaborative problem solving. Within the learning environment, learners are requested to write computer programs to generate geometric figures. The instructional focus of the system is to enhance the learner's List Processor…

As an instructional technology, cognitive apprenticeship has become increasingly important. Cognitive apprenticeship embeds the acquisition of knowledge and skills in their social and functional context and consists of six teaching methods: modelling, coaching, scaffolding, articulation, reflection, and exploration. SMALLTALKER is a…

This book is designed to provide a quick introduction to LinkWay (one of a new generation of hypermedia programs) for teachers who are familiar with other computer applications, but who may not have worked with hypermedia applications. The book serves as a tutorial that quickly introduces the basic elements of LinkWay, thereby making more…

The Comprehensive Unified Physics Learning Environment (CUPLE) is a project that brings together innovative uses of the computer for physics teaching into a single, multi-purpose learning environment. The status of college-level introductory physics teaching is reviewed. In these courses, physics instructors have been forced to be satisfied with…

This book, the 10th volume in the Journal for Research in Mathematics Education (JRME) Monograph Series, discusses the geometry curriculum and investigates how elementary school students learn geometric concepts and how Logo programming and its turtle graphics might affect this learning. This volume also provides details on the development,…

To identify the computer skills that employers expect college graduates to have mastered, a survey was conducted at Cornell University of its corporate recruiters. The questionnaire gathered information in five categories: (1) Creating Documents and Multimedia; (2) Working with Computer Programs; (3) Managing Databases; (4) Manipulating Numeric…

Identifies and describes methods of compiling datasets, search interfaces and etymological metaphors and mythologies of three of the first generation of automated indexing systems: archie, veronica, and robots and search engines. (Author/JKP)

Graphs equations in two variables using a BASIC screen-sweep program that generates solutions to equations by applying the intermediate value theorem. Provides suggestions for investigations that result in graphs of a butterfly, the Cheshire cat, the Trisectrix of Catalna, E. T. waving goodbye, a praying mantis, and others. (MDH)

An intelligent advisor computer program designed to assist undergraduate computer science students in producing an entity-relationship diagram, a conceptual model of a database. The advisor helps students perform modeling exercises and monitors student performance. (MSE)

Most libraries don't have the resources to cross-platform and cross-version test all of their JavaScript coding. Many turn to WYSIWYG; however, WYSIWYG editors don't generally produce optimized coding. Web developers should: test their coding on at least one 3.0 browser, code by hand using tools to help speed that process up, and include a simple…

Examines Internet security risks and how users can protect themselves. Discusses inadvertent bugs in software; programming problems with Common Gateway Interface (CGI); viruses; tracking of Web users; and preventing access to selected Web pages and filtering software. A glossary of Internet security-related terms is included. (AEF)

Reports that student computer programmers from Russian universities, despite outdated equipment, poor facilities, and meager salaries, recently dominated the International Collegiate Programming Contest World Finals with the team from St. Petersburg State University winning first place. Western companies are developing arrangements with Russian…

Discusses the results of a survey to gain insight into the relationship between the acquisition of Object Technology (OT) concepts and previous software development experience. Indicates that the fundamental concepts of OT and the management of OT projects are not difficult to understand while analysis and design topics are harder. (Contains 18…

In introductory computer science courses, the Unified Modeling Language (UML) is commonly used to teach basic object-oriented design. However, there appears to be a lack of suitable software to support this task. Many of the available programs that support UML focus on developing code and not on enhancing learning. Programs designed for…

There has long been controversy in this country about the implementation of school-based sexuality education. In recent years, however, the controversy has centered on abstinence education. Critics of abstinence education programs seem to have three major concerns relative to abstinence education programming: (1) promotion of religion; (2)…
