Interactive Visualization with Git

Title	Git: Interactive Visualization
Overview	Students learn from an interactive visual git simulator / game. This activity cover both local (on your laptop) and remote (internet-based code repository) Git functionality.
Prerequisite Knowledge	Git: Introduction to Github and Git: Working Locally from the Command Line or an introductory understanding of what SCM is about, and basic git commands.
Learning Objectives	Students will be able to ... Create a branch. Checkout a branch. Create a tag. Checkout a tag. Merge a branch into another. Rebase a branch onto another. Cherry-pick commits. Use relative commit references to refer to commits. Move branches to a different commit. Detach and move around HEAD. Explain the difference between a branch, a tag, and HEAD. Clone a remote repository. Fetch changes from a remote repository. Merge changes from a remote repository. Rebase changes from a remote repository. Describe the difference between _rebase_ and _merge_. Push changes into a remote repository. Describe the relationship between `git fetch`, `git merge`, and `git pull` Describe the relationship between `git fetch` and `git push`. Delete a remote branch. Push changes into a remote repository after remote history has diverged.

Suggestions to Open Source Mentors:

Suggestions for an open source community member who is working in conjunction with the instructor.

• Mentors might show what websites and resources (Stackoverflow, IRC, etc) they often utilize when they are stuck or something unexpected happens upon committing or branching.
  • What troubleshooting steps do they use in their head?
  • Do they chat or talk to fellow project-members or work colleagues?
