Abstract

Should the introduction to computer science be an introduction to programming?
If so, which programming language, or paradigm, should be used?
If we omit programming from the first course, what should be taught in its place?

No consensus has yet been reached on the most effective way to approach the first year of computer science education. Perhaps no such consensus should be reached. Regardless, a variety of lessons have been learned regarding effective and ineffective teaching practices in educating the next generation of computer scientists. While most strategies take a programming-first approach, their choice of environment, language, and paradigm often differ. Some strategies regard object-oriented programming as the appropriate introductory paradigm, while others focus on functional. Some construct their programming curricula around graphics and game development, while others use new, less traditional, visual programming languages and environments specially geared for the first course. Still other strategies try to provide a curriculum that focuses more on covering the breadth of the field, as others focus on history, algorithms, and data structures while not using computers at all. Objectives for the various strategies remain as varied as the curricula themselves, with many striving for an increase in student enrollment, some for greater gender equity, some focus on computer programming, while others focus on greater breadth. The presentation will describe eight categories of approaches used for teaching CS 1 with some attention paid to improving the gender ratio in our classrooms.

Biography

Scott Fletcher is in the final quarter of his MSCS degree at Portland State University. He received his BSCS degree in 1996 at Mary Washington College in Fredericksburg, VA. In between the two, he worked professionally as a software developer, parachute packer, bus driver, and most recently spent seven years teaching programming and computer science at Park View High School in Sterling, VA. He is particularly interested in seeing people of all backgrounds learn how to program and believes that acquiring such an ability will help non-computer scientists raise their own fields of study to the next level.
