Strategy Analogy Content Introduction to HyperCard Title What A Card Number of participants 15 Time required 30 minutes Target Audience Beginning HyperCard users ages 12 and up Goal of Activity To learn the basic anatomy of cards and stacks in HyperCard Purpose of script To show how to use physical objects to represent displays on a computer screen Learning Outcomes Gagn s Taxonomy Defined concepts Learning Outcomes HEO Taxonomy Understanding Learner Characteristics Curiosity anxiety Entry Skills Ability to use a keyboard and mouse with or without instruction Setting Classroom with a Macintosh computer for each student Media several blank 5x8 note cards Macintosh computer with HyperCard installed One 5x8 card with a 5x8 mylar sheet attached to it with Scotch tape along the top edge A Rolodex card file Process 1 Explain that HyperCard generates a series of screen displays called cards which can each be used to display graphics and text Explain the computer file containing the cards is called a stack Display the stack of 5x8 cards as an analogy for the contents of the HyperCard stack 2 Explain that the stack does not stop at the beginning and end rather it goes around and around in either direction Display the Rolodex card file as an analogy 3 Show the 5x8 card with the mylar sheet attached to demonstrate a transparent foreground layer and an opaque background layer Explain that each card in HyperCard has analogous layers Lift and lower the mylar layer Ray Bland ISD 613 Fall 96 page 1 on its tape hinge as an analogy for showing the background layer alone and the background and foreground together 4 Have the students make a HyperCard stack with 3 cards displaying different graphics on the foreground of each Use keyboard arrow keys to move continuously in either direction among the cards Remind the students of the Rolodex analogy 5 Have the students draw graphics on the background of one card to demonstrate ability to move from foreground to background and to see how changing one background changes all Strategy Assessment The strategy will be assessed with the following self check 1 Students are able to access HyperCard on the computer and follow instructions for creating a practice stack 2 Students are able to transfer concepts from the physical objects used for analogy to the electronic representations on the computer screen 3 Students are able to state the similarities between the analogy and what they are experiencing on the computer Author Ray Bland Reference West C K Farmer J A Wolff P M 1991 Instructional design Implications from cognitive science Boston Allyn and Bacon Ray Bland ISD 613 Fall 96 page 2
