This document discusses the basic concepts of computer programming including sequential processing, conditional execution, looping, reductionism, and functions. It explains that while computer programs are made up of simple ideas like instructions, conditions, and repetition, combining these building blocks in different ways is what makes programming complicated and powerful. The most important part of learning to program is learning how to think about arranging instructions in sequence.

1. Why learn programming? Programming for the Non-Programmer in Alice 2.2

2. What is a Computer Program? A set of instructions that tell the computer what to do

3. Why include Documentation? Part of a program Explanation to others what you were trying to accomplish //show the break through the thin ice if she skates on it

4. All computer programs are made from a few very simple ideas….

5. Sequential processing List of instructions

6. Conditional Execution “ IF”s if , condition then result

7. Conditional Execution “ IF”s if , then

8. Conditional Execution “ IF”s if , then

9. Looping (Iteration) Repeating behavior work until the bell!

10. Reductionism or Top-Down Design Breaking things up into smaller chucks Clean your room! Make your bed Pick up clothes Put away “toys” Dirty to wash Clean in drawers

11. Reductionism or Top-Down Design Breaking things up into smaller chucks

12. Calling a function Compute a result Perform series of steps to get result ? Get phone book Look up “Father Ryan” in F section Find phone number What is the school’s phone number?

13. Mix & Match as needed!

14. Think of Chess Only 6 pieces Each moves in simple pattern Chess is complicated game because of all possible combinations of moves!

15. Learning HOW TO THINK about arranging sequence is probably the of learning to program! most valuable part
