Squeak

MARK GUZDIAL is an Associate Professor with the College of computing at the Georgia Institute of Technology. His research focuses on learning sciences and technology, specifically, "collaborative Dynabooks," which are tools that support learning through collaborative multimedia construction. He has been teaching object-oriented analysis, design, and programming in Smalltalk for over five years. He received the Ph.D. degree in Education and Computer Science from the University of Michigan. Georgia Tech praised his teaching with an award for "Outstanding Use of Educational Technology" (1997). He has received a prestigious National Science Foundation CAREER Award. He is on the editorial boards of IEEE Multimedia, Journal of the Learning Sciences, Journal of Interactive Learning Research and Interactive Learning Environments Journal.

Introduction.
I. FOUNDATIONS OF OBJECT-ORIENTED PROGRAMMING AND SQUEAK.

1. Objects, Smalltalk, Dynabooks, and Squeak: Where the Objects Come From.


Object-Oriented Programming. Birth of Objects. “A Personal Computer for Children of All Ages.” Back to the Future. Common Ancestry of Other Object-Oriented Languages.

2. A Tour of Squeak.


Basic Rules of Smalltalk. Doing “Normal” Things in Squeak. Doing “Object” Things in Squeak. Using Squeak. Tools and Strategies: Finding More in Squeak. How Do You Make an Application in Squeak?

3. Your First Program: Joe the Box.


Adele Goldberg's Joe the Box. Tools and Strategies: Filling in New Code. Playing with Boxes. Creating the Box Class and Box Instances. Basics of Drawing. Extending Box to Create NamedBox. Tools and Strategies: How to Go from “Sample Code” to “Reuse.” Improving Boxes: Efficiency, Animation, and Design.

4. Designing Object Systems.


The Object-Oriented Design Process. Your First Design: A Clock. Specializing Clock as an AlarmClock. Reusing the Clock and AlarmClock. Implementing Models. Rules of Thumb for Good Object-Oriented Designs. Tools and Strategies: Programming in Groups.

5. Building User Interfaces in Squeak.


Issues in Building a Use Interface. Developing Model-View-Controller. Building Pluggable User Interfaces in Squeak. Building Morphic User Interfaces. Tools and Strategies: Using Morphs That You Haven't Met Yet.

6. Designing User Interfaces in Squeak.


Know Thy Users for They Are Not You. Understanding the User. Matching Users to Interface: Avoiding User Error. A User-Interface Design Process. Critiquing Our Clock Interface. Evaluation of User Interfaces.

7. Multimedia Nuts-and-Bolts.


Text. Graphics and Animation. Sound. New Media in Squeak. Making the Dynabook in Squeak.

II. CASE STUDIES.

8. Case Study: Audio Notes.


Motivation for Audio Notes. Using Audio Notes. Details on Use. Object-Oriented Design and Programming of Audio Notes. Evaluating the Design and Interface.

9. Case Study: Pluggable Web Server and Swiki.


Networking Support of Squeak. Swiki as a PWS Application.

10. Case Study: MAT (Multimedia Authoring Tool).


Motivation for and Use of MAT. Object Design and Programming in MAT. User Evaluation of MAT.

11. Case Study: Prototyping a Playwriting Workbench.


Motivation and Setting the Goal. Object Analysis of the Workbench. Implementation of the Play Workbench. Iterating on the PlayBench. Evaluating the PlayBench: Expert Evaluation and Observation.
