Study Notes
Computational Thinking Introduction
- Computational thinking was first introduced by Seymour Papert in 1980, but later popularized by Jeanette Wing in 2006.
- It's a problem-solving approach.
- It involves formulating problems and their solutions in a way that can be effectively processed by an information-processing agent.
- Initial ideas of computational thinking may appear complex.
- The number of components varies in definitions; some definitions have 3, 4, 5, or 6.
Concepts of Computational Thinking
- Decomposition: Breaking down large problems or tasks into smaller, manageable parts.
- Pattern Recognition: Identifying similarities in problems and how they relate to each other.
- Abstraction: Focusing on essential information and details while ignoring unnecessary facts. It's also called generalization or categorization.
- Algorithm Design: Developing step-by-step solutions or rules to solve problems.
Logical Reasoning
- Deduction: Drawing a conclusion from accepted facts. Example: All men are mortal; Bjorn is a man; therefore, Bjorn is mortal.
- Induction: Reaching a conclusion from observations. Example: Bjorn is mortal; Bjorn is a man; therefore, all men are mortal.
- Abduction: Reaching a likely conclusion based on existing knowledge. Example: All men are mortal; Bjorn is mortal; therefore, Bjorn is a man.
Logical Reasoning - Example
- Four friends are seated in a cinema.
- Ann is in seat H3.
- Ravi is to the right of Ann in seat H4.
- Siobhan is to the left of Ann.
- Eve is to the left of Siobhan.
- What seat is Eve in?
Abstraction
- Abstraction focuses on essential elements of a problem while ignoring other details.
- This can be an important method to solve complex problems more easily.
- This is also known as generalization.
Decomposition
- Decomposition involves breaking down complex problems into smaller and manageable parts.
- It's often used in projects that span a long time or have many tasks.
Pattern Recognition
- Pattern recognition identifies similarities between problems, often leading to easier algorithm design.
Algorithm Design
- Algorithm design refers to formulating step-by-step solutions to problems.
- This can be described as creating a set of logical rules.
Evaluation
- Evaluation involves checking if the solution functions appropriately and addresses the problem effectively.
- It also involves correcting errors.
Critique of Computational Thinking
- Computational thinking is a relatively new field with broad applications.
- Many definitions vary, making it difficult to define definitively.
- It can be vague and lacks specifics.
- It hasn't fully considered many implications (social, ethical, environmental) involved in the subject.
- There is uncertainty about cultural context.
