  1. Changes to CS3 CurriculumSummer 2013 SuziGerb

  2. Changes in a Nutshell • Placed on the web in a wiki • https://cs3.wikispaces.hcpss.org/home • Simplifications and additions • Lab changes • BCD5 requires 2d arrays • GridWorld projects • Independent “capstone” style project

  3. Simplifications and Additions • Went from more than 20 units down to 11 • Added a lesson on 2d Arrays • Added a unit on GridWorld • Updated “How to teach this class” document • Added a teacher’s guide to CS3 labwork

  4. BCD 5 changes • BCD5 allows you to multiply two BCDs • Used to be implemented using repeated addition • Now uses the Lattice Method of multiplication. • Requires two-dimensional arrays.

  5. Four GridWorld Labs • Part 1: Very simple. Start up GridWorld and run at least one demo • Part 2: Write a proposal for an extended project. Must be one of CritterBrain, GameBug, or StoryBug • Part 3: Create a subclass of one of the testable actor classes. • Part 4: Extended project

  6. CritterBrain • Very challenging project • Artificial Intelligence • Write a class to make decisions for an instance of SmartCritter to keep it alive • Needs to be able to find bugs for food • Needs to be able to evade stronger critters that can eat it • Class will be a subclass of CritterBrain • Software provided for two CritterBrains to compete to see which survives the longest

  7. GameBug • Subclass of Bug • Allows students to extend it to create a GridWorld-based video game • Keyboard manipulation • Reports health and points • By specializing methods, students decide • How the GameBug moves • What happens when it touches another bug • What happens when it picks a flower

  8. GameBug demos • Bowling bug • If it touches other bugs it loses health • Can touch a HealingBug (hard to catch) to regain health • Can fire bowling balls (subclass of rock) to knock out bad bugs • Bowling balls obtained by picking flowers • Maze Bug • Trying to reach the center of a maze • Must avoid the critters moving around the maze

  9. StoryBug • Allows the student to use subclasses of a StoryBug class as characters in a story • Can create and find graphics for images • Can speak by popping up dialog frames on the screen • A little easier than the other two projects • Brief demo story provided

  10. Independent project • Open-ended “capstone” style project. • Contract based • Student submits a proposal • Teacher gives numerical scores to the various goals within the proposal • Student graded based on how many they achieve • Contract contains • Prototype • Main project • Two levels of enhancements
