Adventures in Computational Thinking By Wendy Hu Overview
Adventures in Computational Thinking By Wendy Hu Overview Computational Thinking During this quarter we have learned about Information Technology (IT) fluency, including proficiency with certain computer applications (traditional computer literacy), principles on which you can build new understanding as IT evolves, high-level reasoning and IT problem solving, and basic web programming (HTML and Java. Script). Computational thinking, data analysis and data presentation have been the main themes throughtout. Visual Programming with Scratch is a programming language developed by the Lifelong Kindergarten Group at the MIT Media Lab to help young people learn how to develop computer programs. Data Analysis and Visualization with Excel Presentation of Information with Word & Power. Point • One of the most common uses of a spreadsheet is to chart financial information. • We created an annual budget for ourselves, so we can monitor our spending while here at UCSD and calculate how much discretionary spending money we have each month. • We were encouraged to use real information (they promised not to look other than to help/check us off!) but if we didn’t feel comfortable with that, could feel free to make up numbers – they wouldn’t know if it was real anyway!

The development of Scratch (and its name) was inspired by the scratching process that DJs use to create new sounds and music by rubbing old-style vinyl records back and forth on record turntables, creating new and distinctively different sound out of something that exists. Per Year • Computational Thinking is thinking at multiple levels of abstraction • For solving problems • For designing systems • For understanding the power and limits of human and machine intelligence • Computational thinking also means being able to go above the original whole and constructing a whole of wholes. Or going above the whole and thinking about the whole in a different way. • The concept of computational thinking is being spearheaded by the Center of Computational Thinking at Carnegie Mellon where their major activity is conducting PROBEs or PROBlem-oriented Explorations Image Analysis and Manipulation with Photoshop Presenting complex raw data into easily understandable charts and grafts displaying it through the filters of Power.
