Hour of Code (code.org) Learn the basic concepts of Computer Science with drag and drop programming. Learn repeat-loops, conditionals, parameters, and basic algorithms.

Hour of Code Example

●  Additional stages featuring The Artist and The Farmer

Intro Course Example

Audra’s Comments ●  Learned about different kinds of blocks ●  Bug fixing problems were easiest ●  Learned how to “read” the blocks and

understand what they would do ●  Fun to draw pictures and being able to

create something

Retrospective Review ●  Learn from experience

●  Build on what works

●  Gain perspective

●  Decide what to do differently

Learn From Experience

Blockly is easier than JavaScript

Code.org activities helped

Forgot details after a long break from modding

Minecraft API harder to understand than coding

We could change the “rules” of Minecraft

Build On What Works Helpful to have a partner LearnToMod •  sets up a server for you •  code in the web browser •  also lets you code in JavaScript

Gain Perspective

Some things just don’t work – and that’s OK •  “order matters” – bug in grading •  “squid launcher” – bug in Minecraft

You need to invest the time to learn

Won’t teach you how to make DragonMounts

Got distracted playing the game with mods

Decide What To Do Differently Extra and unnecessary badges that got boring and felt like wasted time Look for existing in-game commands (e.g. /fill or /summon) Dedicate specific blocks of time
