Overview: Data and Analysis
At the core of computing lies data and analysis. The earliest computers were designed to handle repeated calculations.
According to Virginia Computer Science SOL Introduction, “Data and Analysis involves the data that exist and the Data Analysis that exist to process that data. The amount of digital data generated in the world is rapidly expanding, so the need to process data effectively is increasingly important. Data is collected and stored so that it can be analyzed to better understand the world and make more accurate predictions.”
Big Ideas-Why do students need Data and Analysis?
- Learning to analyze trends across data sets
- Using computing devices to generate data faster and more efficient calculations
- Data aggregations
- Life skill-students need to understand their data is collected and combined in ways most people are not aware of. Students need to understand
Analog vs digital
Encoding is changing information from one form of information into another. Writing letters to represent sounds and words is a form of encoding, just like elevator buttons represent the floors of a building. All of the information that a computer stores and processes, from videos to data about hurricanes, is encoded in binary,
Digitization is the process of encoding information so that it can be processed by a computer. Computer input devices capture information from the world around us and encode it. So a camera translates pictures, microphone translates sounds and an MRI translates internal body structures into data a computer stores and processes.

Overview: Algorithms and Programming
Context This strand is at the core of how computer science gets done. Programming is how humans give instructions to the computer, directions are encoded into commands that the computer follows. Everything a computer does is encoded. This idea of ...
Domains of Facilitation
Context: Just as people in China built the Great Wall to keep out foreign invaders, and the Ancestral Pueblo people in the southwest United States build towns on mesa walls for defensive reasons, communities have always needed to keep themselves ...
Overview: Computing Systems
Context: This strand focuses on the hardware in computers. In computer science, hardware is not just about memorizing components, but rather asking the fundamental question - what makes something a computer? As computers get smaller and invade more ...
