Preparation
Sample poster or tri-fold poster for a fictional game, to use as a model for students.
Once you have a working game (will all your Contracts and EXAMPLEs included, of course!), it’s time to think about how to present your work to others. Programmers spend a lot of time designing and writing their code, but they also spend time explaining their work to others. These might be other programmers on their team, other engineers within the company, or even non-technical people. Do you think you can explain your code to someone else?
Students not finished with their games? You can use the last class to get things done, with a speed-focused game designed to get things done! Got time for a challenge? Try introducing them to Data Structures, to allow for 2-dimensional motion and more player control.
Your name(s), and the title of your game
A picture to catch people’s eyes
The story behind your game
A written description of ONE function from your code. This description should include the Name, Domain and Range of the function, with an explanation of what it does and how it is used in your game.
Make sure that each group of students gets a different function to talk about, so that a classwide presentation will review the entire game. You may also want to have groups assigned to explain the Circles of Evaluation, Contracts, and the purpose behind the Design Recipe.
After you’ve made the poster, think about how you will use it during your presentation. What will you say to the audience? How can you use what you’ve written on the poster or in your code to help with the presentation?
Write or practice a 5min presentation, in which you introduce yourself and explain your game, then walk the audience through an explanation of the function or concept you were assigned.
Have students walk through their presentations, and get feedback from their peers. You may also want to model the explanation of a few lines of code, so they see what you’re looking for. Don’t allow students to just recite the code! They should be able to explain each line in plain english - don’t be afraid to push students to really explain what’s going on.
