Study Notes

Computational Thinking Introduction

Computational thinking was first introduced by Seymour Papert in 1980, then popularized by Jeannette Wing in 2006.
Computational thinking is the thought processes used to formulate problems and solutions that an information-processing agent can effectively execute.
Problem-solving approaches can appear complicated at first glance.
The exact definition varies, sometimes described with 3, 4, 5, or 6 components.

What is Computational Thinking?

Computational thinking encompasses several key concepts:
- Decomposition: Breaking down complex problems into smaller, more manageable parts.
- Pattern recognition: Identifying similarities and common patterns in problems.
- Abstraction: Focusing on essential elements of a problem while ignoring irrelevant details.
- Algorithm design: Creating step-by-step instructions or rules to solve a problem.
- Evaluation: Checking the function or outcome and addressing errors (debugging).

Logical Reasoning

Deduction: Making inferences based on widely accepted facts, such as "All men are mortal; Bjorn is a man; therefore, Bjorn is mortal."
Induction: Drawing inferences based on observations, such as "Bjorn is a man and mortal; therefore, all men are mortal (a generalisation)."
Abduction: Forming probable conclusions based on existing knowledge, such as "All men are mortal; Bjorn is mortal; therefore, Bjorn is a man (a possible conclusion)."

Logical Reasoning Types

Inductive, Deductive, and Abductive Reasoning: Different methods of logical reasoning. Example: Four friends seating at a cinema, using provided data about their seating, to deduce Eve's seat.

Abstraction

Abstraction focuses on the essential elements of a problem and excludes superfluous information.
It is also known as generalization or categorization.
Example: Simplifying a map of a city to focus only on the transportation network.

Decomposition

Decomposition involves breaking down large complex problems into smaller, more manageable components.
This approach is often used for projects and tasks, such as a nuclear plant or a project management approach.

Pattern Recognition

Pattern recognition involves identifying similarities among problems, as well as any patterns that emerge. Knowing past issues or problems to anticipate or address new ones.
Examples may include recognizable shapes, or patterns in data.
Pattern recognition helps in designing effective algorithms.

Algorithm Design

Algorithm design creates step-by-step procedures or rules to solve a problem.
It can be a specific set of instructions for a computer program, or a general process for performing a task.
- Example with a recipe, or calculating journey time (timeDepart, timeArrive).

Evaluation

Evaluation involves checking if the solution functions correctly or achieves expected outcomes.
This includes identifying and correcting issues or errors (debugging) within a solution's procedure.

Critique of Computational Thinking

Computational thinking is relatively new and may not have a clear definition, even possibly lacks clarity in its definition.
Potential implications of this approach, such as social, ethical, legal, and environmental considerations, might not be fully discussed or researched, perhaps vague.
Cultural differences in practices or interpretations may also need to be considered.
