course as an example

Presentation outline

• The modular courseware format • The programming course• Demonstration• Assessment of efficacy• Advantages and disadvantages• Further work

Modules for these topics • Introduction to programming• Network applications • Introduction to Web development • Image processing • Audio and video processing • TCP/IP networking technology • Wireless networking • VoIP • Connectivity • History • Encoding data

Press, L., "Information Processing at Tomorrow's University," Communications of the ACM, Vol. 37, No. 7, pp 13-17, July, 1994.

Modules consist of

• A focused topic note with terms with optional demonstration programs

• Assignments• Review questions

Programming course user interface

92 focused modules and 416 index entries

Presentation outline

• The modular courseware format • The programming course• Demonstration• Assessment of efficacy• Advantages and disadvantages• Further work

Context: the course

• First course in programming• Business IS, High School CS, etc.• Use VB.NET, but could be any language• Stress terminology and concepts• Conventional topics

Topic areas

• Programming languages and terminology• The VS.NET development system• User interface creation and widgets• Event handlers -- sequential execution and

assignment statements• Interactive programs • Numeric, string and Boolean data• Continued …

Topic areas, continued

• Expressions• Variables and scope• Type conversion and checking• Algorithms• Functions• Conditional execution if, case and loops• Sequential files• Arrays

Using the modules in class

• Lecture/demonstration using topic note• One or more assignments with due dates• Food for thought questions on their own• Responsible for key terms

Presentation outline

• The modular courseware format • The programming course• Demonstration• Assessment of efficacy• Advantages and disadvantages• Further work

Context: six dimensions

•Isolated instructional modules vs. an integrated course

•Self-study vs. instructor mediated•Face-face vs. distant education•Joint, open authorship vs. editorial control•Repurposed textbook vs. interactive/executable

material•Degree of correlation between classroom and

courseware
