Overview
This lecture introduces Computational Thinking, its importance in problem solving, and explains its four main foundations with practical examples.
What is Computational Thinking?
- Computational Thinking is a problem-solving process to find effective and efficient solutions.
- It is used in computer science before coding but also applicable in everyday life.
- This approach is key to preparing for complex, real-world problems and decision-making in the digital era.
The Four Foundations of Computational Thinking
- Decomposition: Break complex problems into smaller, manageable parts.
- Pattern Recognition: Identify similarities and recurring patterns in problem parts.
- Abstraction: Focus only on essential information, ignoring irrelevant details.
- Algorithm: Create a step-by-step process or rules to solve the problem.
Practicing Computational Thinking
- Apply the four foundations to everyday situations and more complex tasks.
- Practice Computational Thinking questions in various subjects like mathematics, language, and science.
- Participate in challenges, such as the Bebras Indonesia Challenge, to sharpen these skills.
Example Problem: Luggage Storage Order
- A question asks which group’s suitcase should be put last in a bus with one-sided luggage access and multiple drop-off destinations.
- The logic requires arranging suitcases so those needed first are most accessible, meaning the last destination's suitcases are packed last.
Key Terms & Definitions
- Computational Thinking — A methodical approach to problem-solving based on effective and efficient strategies.
- Decomposition — Dividing complex problems into simpler sub-problems.
- Pattern Recognition — Detecting similarities or repeated elements among problem components.
- Abstraction — Filtering out unnecessary information to focus on what matters most.
- Algorithm — An ordered set of steps to solve a problem.
Action Items / Next Steps
- Practice applying decomposition, pattern recognition, abstraction, and algorithms in daily life and schoolwork.
- Attempt the sample luggage problem and similar Computational Thinking questions.
