Overview
I promised to share the weighting of each of the five big ideas on the AP Computer Science Principles exam. The College Board gives them to us in AP Computer Science Principles at a Glance.
They are:
- Big Idea 1: Creative Development: 10-13%
- Big Idea 2: Data: 17-22%
- Big Idea 3: Algorithms and Programming: 30-35%
- Big Idea 4: Computer Systems and Networks: 11-15%
- Big Idea 5: Impact of Computing: 21-26%
Friday, January 20th
After we take our quiz today on Big Idea 1: Creative Development, we will organize ourselves into groups of 3 or 4 to work on a project for the next Big Idea 2: Data.
Classwork / Homework
Choose one of the key concepts from Big Idea 2: Data below, and develop a mini-CPT project around it:
- Abstractions such as numbers, colors, text, and instructions can be
represented by binary data ("It's all just bits!").
[Toby, Sean, Evan and Xander] - Numbers can be converted from one number system to another. Computers use
the binary number system ("It's all just bits!" ;-).
[Jake, Conrad and Grant] - Communicating information visually helps get the message across.
[Jack, Alex, Noah and Kellan] - Increasing needs for storage led to the development of data compression
techniques, both lossless and lossy.
[Emory, Christian, Eimi and Lary] - Data mining, the process of using computer programs to sift through data
to look for patterns and trends, can lead to new insights and knowledge.
[Rockwell, Ronan and Gabriel] - It is important to be aware of bias in the data collection process.
[Anupama, Blu, Kiersten and Mayah]

Classwork
During class on Wednesday we will share our presentations on Big Idea 1: Creative Development
Homework
Study for the quiz on this big idea at the beginning of class on Friday. Pay particular attention to the vocabularly terms you were asked to define last week.
