In the current digital age, computational thinking stands as a vital cognitive skill.
It refers to the ability to solve problems and tackle challenges using approaches similar to those applied in programming and computing.
In this article, we’ll delve into the intricacies of computational thinking, the phases that comprise it, the defining traits that characterize it, and we’ll provide illustrative examples of its application.
What is Computational Thinking?
Computational thinking involves breaking down complex problems into smaller, more manageable parts.
Think of it as disassembling a puzzle to understand how the pieces fit together. This skill enables you to address any problem, not just tech-related ones, in a structured and logical manner.
Computational thinking promotes step-by-step problem-solving and identifying patterns to arrive at efficient solutions.
While the definition might make it seem recent, it’s not a new concept. Its roots can be traced back to the beginnings of computing and programming.
As technology advanced, the foundations of computational thinking were laid, although it wasn’t referred to as such at the time. Computing pioneers like Alan Turing, Claude Shannon, and Grace Hopper established the groundwork for logical and algorithmic approaches to problem-solving.
Over time, computational thinking expanded beyond programming boundaries and began to be applied across various disciplines.
As computers became more accessible, people started adopting computational approaches to address everyday life, science, engineering, and more.
Phases of Computational Thinking
Computational thinking is broken down into several phases that facilitate problem-solving:
1. Problem Identification
The first phase involves clearly defining the problem that needs to be solved. This includes understanding the requirements, limitations, and goals of the problem at hand.
In this stage, the problem is broken down into smaller, more manageable subproblems. Each subproblem is addressed separately to avoid feeling overwhelmed by the complexity of the main problem.
3. Pattern Recognition
Pattern recognition involves identifying similarities or regularities within the subproblems. This phase allows for discovering general approaches that can be applied to various aspects of the problem.

Abstraction entails removing unnecessary details and focusing on the fundamental aspects of the problem. This helps simplify the resolution process by highlighting what truly matters.
During this phase, algorithms or organized sets of logical steps that lead to the solution of each subproblem are developed. Algorithms are like recipes that guide you through the resolution process.
6. Evaluation and Refinement
After applying the algorithms, the obtained solutions are evaluated and refined if necessary. This phase ensures that the solutions are effective and efficient.
Key Traits of Computational Thinking
The following factors characterize computational thinking:
- Systematic Approach: It adopts a step-by-step and organized approach to address problems, facilitating the effective resolution of complex tasks.
- Pattern Utilization: Identifying patterns in problems and solutions enables the application of proven solutions to similar situations.
