Tech Eval Questions

Introductory questions

  • How did you find the reading?
  • Do you have any questions about anything in there?

Section 1: Reading code

Q: What would the output of this program be? Q: There are 6 steps in this program. What would be on the list at each step?

What we're looking for

Students should get through these with minimal prompting. Look for them working step-by-step, talking about what's in the list after each instruction is run. They should be referring back to the overview in the writing for definitions of the instructions - point them in that direction if they have forgotten what some of the instructions do.
