Chapter 1: Telling a Story

1. Telling a Story

Big Ideas: Sequential and Parallel Execution, How to Write a Program

  • Computers do things by executing a sequence of instructions.
  • Have students translate an English "plan" into Alice code.
  • Test frequently - it's good practice and will save you a lot of frustration.
  • Instructions can be executed Do in order or Do together. (In a Do together tile, the order of the instructions doesn't matter).
  • You should be able to predict what a program does, then test your prediction by playing/running the program.
  • Computers are very picky -- they do exactly what you tell them to do.

Vocabulary for this module:

Code/Program: A collection of instructions that humans write to tell a computer what to do.

Instruction/Statement: A specific task (usually very simple) you can give a computer.

Plan/Storyboard: A written-down English description of something (an animation for now) you want to make Alice do.

Test: Hit play to see if your code/program does what you think it will do.

NOTE: See Instructor Resources at the end of this module for things to do after students have finished the online module (e.g., giving a quiz or assessing their learning of the online module, doing clicker questions to deepen understanding/go into challenging aspects, lab).
