Overview

• Summary of Media Computation Innovation at Georgia Tech Overview of successful results

• Adaptation at Gainesville College Results at Gainesville College

• Key Findings• Current/Future Work

What is Media Computation?

• Introductory CS course with focus on Learning to program and CS concepts within

the context of media manipulation and creation Converting images to grayscale/negatives Splicing and reversing sounds Writing programs to generate HTML web pages Creating movies by sequencing images

Computing for communication, not calculation

• For non-CS majors Liberal arts, management, architecture and

biology majors

Overview of Syllabus

• Programming Language Python

• Pictures Data structures, defining

functions, for loops, if conditionals

• Sounds Data structures, defining

functions, for loops, if conditionals

• Text Converting between

media, generating HTML• Movies

• Traditional CS Topics Algorithms Representations Can’t we do this any

faster? Machine language,

interpreters, and compilers Algorithm complexity &

limits of computation

Can’t we do this any easier? Modularity, recursion, OO

• But majority of students at both institutions perceived skills would be useful later in life 59.9% - Georgia Tech 56.2% - Gainesville

• Georgia Tech students saw greater relevance of course material for career 45.5% - Georgia Tech 37.5% - Gainesville

Attitudes & Perceptions

• Almost all students at both institutions reported improved programming skills 91.6% - Georgia Tech 87.5% - Gainesville

• Georgia Tech students reported greater confidence in their programming abilities (rated their programming skills as strong or very strong) 75.8% - Georgia Tech 68.8% - Gainesville

Insights

• Common in Adaptations Improvement in Success Rates

Anecdotal evidence shows improvement in almost all adaptations, but not always dramatic

Attracting alternate student populations Increased female enrollment in courses Women & minorities are succeeding at the same rates

as male students Computer art, architecture
