Computational Thinking: A 21st Century Skill

There are various terms like computer science, computational thinking, and programming, each serving a unique purpose. While computer science focuses on academic discipline, computational thinking is more about problem-solving, integrating skills fromÂ computer science into everyday scenarios. Programming, on the other hand, involves creating instructions for computers to follow.

But computational thinking goes beyond coding. It’s about leveraging these skills across different subjects and real-life situations, from math to social studies, to solve problems creatively and efficiently. In this article, you will get a comprehensive understanding of computation thinking, its components, and how it is important in the new digital age.

What is Computational Thinking

Computational thinking (CT) involves the cognitive processes used to define problems so that their solutions can be described as computer-based steps and algorithms. In education, CT includes problem-solving methods where problems and solutions are expressed in ways that a computer can understand and execute. This includes automating tasks and using computers to explore, analyze, and understand both natural and artificial processes.

Computational thinking involves a set of skills and methods to solve complex problems, help learn in different subjects, and is crucial for thriving in today’s digital world.

When we talk about computing, computer science, computational thinking, and programming, we use many terms. Computing includes skills and methods from both computer science and computational thinking. While computer science is its own academic field, computational thinking is a problem-solving approach that goes beyond specific tasks. Programming, meanwhile, is about creating instructions that a computer can follow, including fixing errors and using the code for problem-solving.

Four Components of Computational Thinking

No matter if computational thinking is used in computer science or other fields, it can be divided into four main parts.

Decomposition:

Decomposition is the first step in computational thinking. It means breaking a complicated problem into smaller, easier-to-handle parts. This step is crucial because it helps us understand and approach the problem systematically. Decomposition simplifies the problem by splitting it into smaller pieces, making it easier to solve. Think of it as eating an elephant â€“ you have to take it one bite at a time.

Pattern Recognition:

Pattern recognition is another important part of computational thinking. It involves spotting repeating patterns or connections among different parts of the problem. Pattern recognition aims twofold: to simplify the problem by finding similarities or differences among its details and to deepen our understanding of the main issue.

Abstraction:

Abstraction means taking out the most important information from each part of a problem. This helps in understanding what exactly needs to be solved to tackle the problem effectively. When students abstract, they can see how these important details might be useful in solving other parts of the same problem.

Algorithmic Thinking:

Algorithmic thinking is the last part of computational thinking. It involves creating a step-by-step plan to solve the problem systematically, ensuring a predictable and reliable result. In today’s computational thinking, especially in computer science, this plan usually involves a sequence of actions carried out by a computer. However, people can also use this process, either fully or partly.

Steps to Implement Computational Thinking

To make predictions using computational thinking, you would start by defining three essential steps in relation to the problem and its solution:

1. Problem Specification: Begin by analyzing and precisely defining the problem, setting specific criteria for its solution. Computational thinking involves breaking down complex issues into more manageable sub-problems through deductive or probabilistic reasoning, a process known as problem decomposition. This approach often utilizes abstraction and pattern recognition, crucial for creating models and simulations.
2. Algorithmic Expression: Next, identify an algorithmâ€”a precise sequence of stepsâ€”to solve the problem using appropriate data representations. This step employs inductive thinking, enabling the transfer of a specific problem to a broader class of similar problems. This phase, also known as algorithmic thinking, can be divided further into imperative (procedural or modular) and declarative (functional) approaches to algorithmic solutions.
3. Solution Implementation & Evaluation: Finally, implement the solution and systematically evaluate its correctness and efficiency. This stage includes assessing whether the solution can be automated or extended to address other types of problems.
