Use of Hypercard to Create Pages on the World-Wide

Behavior Research Methods, Instruments, & Computers 1997,29 (2), 182-188 CONSTRUCTION AND MAINTENANCE OF WORLD-WIDE WEB SITES Moderated by John H. Krantz, Hanover College Use ofHyperCard to create pages on the World-Wide Web RON HOFFMAN and JOHN MAcDONALD Dalhousie University, Halifax, Nova Scotia, Canada A variety of commercial and shareware programs are now available to assist in creating HTML pages for a World-WideWeb (WWW)site. However, users with some knowledge of HTMLcoding and a simple programming language, such as the HyperTalk language in HyperCard, can create custom tools that will simplify the task of creating and maintaining multiple-page WWW sites. This paperpre sents examples of two such tools and describes the basic steps they use to create HTMLdocuments. Psychologists are being urged to create sites of home Users of Macintosh computers often have the Hyper pages on the World-Wide Web (WWW) for a variety of Card program available. HyperCard has a variety ofuses purposes. These include departmental information pages in psychology labs, including hypermedia teaching pro (Plaud, 1996), tutorials or teaching resources (Krantz & grams (Carreras, 1993; Dougherty, 1990) to demonstrate Eagley, 1996; Trapp, Hammond, & Bray, 1996), confer psychological phenomena; research tools (Gonzalez, ence announcements (Mainwaring, 1996), or research 1993; Hoffman & MacDonald, 1993) for gathering data; data gathering (Schmidt, 1997).
