Introduction
In this Quest, you will explore the concept of abstraction and learn how to focus only on the important details when solving a problem.
Abstraction is one of the most challenging stages of computational thinking. It allows programmers to simplify complex problems by hiding unnecessary details and emphasizing only the relevant information, making their programs more efficient.
Play the video below. Think about how the ideas of abstraction relate to your ideas of learning. Be prepared to discuss with your classmates.
Computer Science Concept - Abstraction (1:11 min.)
In the video, they talk about maps and abstraction. If someone wants to find all 50 states, they use a political map. This type of map only shows states, cities, and countries, not details like rivers, lakes, or mountains. Those details are hidden because they aren't needed for finding state locations. A physical map, however, is used for a different purpose—it helps people see land features like mountains, rivers, and terrain.
When solving a complex problem, it's important to find the simplest way to do it while keeping the important details. For example, when researching online, you choose the best keywords to find the right information. When giving a presentation, you focus on the main points. Too many extra details can be distracting.
Learning Objectives:
I can:
- Understand abstraction.
- Hide details that are needed.
