Programming with Scratch Harvey Siy hsiy@unomaha.edu http://www.cs.unomaha.edu/~hsiy Getting Computer Science into the K-12 Curriculum CodeCrush Outline • Computational thinking • Introduction to Scratch • Short exercise • A more complicated example • Discussions 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush Computational Thinking is… A problem solving approach… … solving a problem by explaining the steps needed to arrive at the solution To explain the steps, you have to: • come up with the steps • communicate them • defend them 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush Explaining the steps • come up with the steps – involves creativity – involves recognizing similar situations • communicate the steps – how can I express them clearly? * step-by-step procedure for solving a problem – involves creating an algorithm* – forms the basis of computer programming • defend the steps – are these the right steps? – will these lead to a correct solution? – involves logical reasoning and critical thinking 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush Teaching Computational Thinking • Coding is the most fun way to practice computational thinking • Lots of resources for all grade levels from Hour of Code: http://code.org/learn 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush Scratch • http://scratch.mit.edu • Fun and easy to learn • Develops creativity 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush Development Environment 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush Development Environment 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush Development Environment 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush Development Environment 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 10 Physical interactions • Scratch offers additional forms of interaction beyond the traditional keyboard and mouse • Sensor boards – Picoboard (currently 1.4) – Makey Makey – Lego WeDo (currently 1.4) • Kinect (currently 1.4) • Webcams (2.0 only) 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 20 Example 4: Webcam interaction Detect motion by webcam “Faster” motion detected: move sprite up Remember to turn off webcam when done! “Slower” motion detected: move sprite down Access the working version at: http://scratch.mit.edu/projects/10673482/ 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 21 Makey Makey See demo at: http://vimeo.com/60307041 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 22 Makey Makeys in action 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 23 Picoboard Slider Light sensor Button Clips 2/26/2014 Sound sensor Getting Computer Science into the K-12 Curriculum CodeCrush 24 Picoboard controls (1.4) Sensing button sensor value sensor condition test 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 25 Comparable languages 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 26 Alice 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 27 Snap • Spinoff from Scratch • Supports – Higher order functions – Recursion – Lists of lists 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 28 Greenfoot A gentle transition into Java 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 29 CS Unplugged • http://csunplugged.org • Computational thinking without computers! 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 30 Computational Thinking across the curriculum Computational science Scientific visualization Multimedia Science Visual/ Performing Arts CT Digital humanities Language Arts Technology Engineering Information technology Modeling, Simulation Computer-aided design Math Automated theorem proving, Numerical analysis 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 31 Computational Thinking courses Exploring Computer Science http://www.exploringcs.org/ Computer Science Principles http://www.csprinciples.org/ 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 32 Some CS Resources • J Wing Computational Thinking, Communications of the ACM, March 2006 • Computer Science Teachers Association, http://csta.acm.org • Google Exploring Computational Thinking, http://www.google.com/edu/computational-thinking • CS Unplugged, http://csunplugged.org • Yadav Computational Thinking in K-12 Education, http://cs4edu.cs.purdue.edu/_media/ct-in-k12_edps235.pdf – See the list of resources near the end 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 33 Scratch Resources • Website: http://scratch.mit.edu (lots of examples) • Curriculum Guide: http://scratched.media.mit.edu/resources/scrat ch-curriculum-guide-draft • After-school lessons: http://scratch.redware.com/lessonplan 2/26/2014 Getting Computer Science into the K-12 Curriculum CodeCrush 34 ... http:/ /scratch. mit.edu/projects/10597215/ 2/26 /2014 Getting Computer Science into the K-12 Curriculum CodeCrush 18 Example 3: Sorting • Download the Scratch programs from http://code.google.com/p /scratch- unplugged/...
