This is a supplemental Website for the following book chapters:
E-Learning components are clustered into the following seven categories. However, as the e-learning methodologies and technologies continue to improve, some existing components within the seven categories may need to be modified or deleted and new e-learning components may be available to be added to the following list. Newly added or modified components can be found at http://BooksToRead.com/wbt/component.htm). 1. Instructional Design (ID) a) Learning and Instructional Theories b) Instructional Strategies and Techniques 2. Mutimedia Component a) Text and Graphics b) Audio Streaming (e.g., Real Audio) c) Video Streaming (e.g., QuickTime) d) Links (e.g., Hypertext links, Hypermedia links, 3-D links, imagemaps, etc.) 3. Internet Tools a) Communications Tools i) Asynchronous: E-mail, Listservs, Newsgroups, etc. ii) Synchronous: Text-based (e.g., Chat, IRC, MUDs, messaging, etc.) and audio-video conferencing tools. b) Remote Access Tools (Login in to and transferring files from remote computers.) i) Telnet, File Transfer Protocol (ftp), etc. c) Internet Navigation Tools (Access to databases and Web documents.) i) Text-based browser, Graphical browser, VRML browser, etc. ii) Plug-ins d) Search Tools i) Search Engines e) Other Tools i) Counter Tool 4. Computers and Storage Devices a) Computer platforms running Graphical User Interface (GUI) based operating systems such as Unix, Windows, Macintosh, Linux and non-GUI based operating systems such as DOS. Mobile devices such as handheld personal digital assistants (PDAs) running Palm operating system, Pocket PC Windows and other platforms. b) Hard drives, CD ROMs, DVDs, etc. 5. Connections and Service Providers a) Modems b) Dial-in (e.g., standard telephone line, ISDN, etc.) and dedicated (e.g., 56kbps, DSL, digital cable modem, T1, E1 lines, etc.) services (http://whatis.com/dsl.htm) c) Mobile technology (e.g., connected wireless, wireless LAN, wireless WAN, wireless PAN or personal area network) (Polivka, 2001) d) Application Service Providers (ASPs), Hosting Services Providers (HSPs), Gateway Service Providers, Internet Service Providers (ISPs), etc. 6. Authoring/Management Programs and Standards a) Scripting Languages (e.g., HTML - Hypertext Markup Language, VRML - Virtual Reality Modeling Language, XML - Extensible markup Language, XSL - Extensible Style Sheet language, XHTML - Extensible Hypertext Markup Language, CSS - Cascading Style Sheets, WML-Wireless Markup language, Java, Java scripting, etc.). b) Learning Management System (LMS) and Learning Content Management System (LCMS) c) HTML Converters and Editors, etc. d) Authoring Tools and Systems (easier to use than programming languages) e) Interoperability, Accessibility and Reusability Standards (http://www.adlnet.org/) 7. Server and Related Applications a) HTTP servers, HTTPD software, etc. b) Server Side Scripting Languages - JavaServer Pages (JSP), Active Server Pages (ASP), ColdFusion, Hypertext Preprocessor (PHP), Common Gateway Interface (CGI)-a way of interacting with the http or Web servers. CGI enables such things as image maps and fill-out forms to be run. Wireless Application Protocol (WAP) gateway-changes the binary coded request into an HTTP request and sends it to the Web server.
