Key Takeaways from Leaving Certificate Business Studies Notes: Abstraction & Computational Thinking

• Computational Thinking: Computational thinking involves approaching problems logically to find solutions. It has four key pillars: Abstraction, Pattern Matching, Decomposition, and Algorithms. These principles help break down complex problems and create efficient solutions.

• Abstraction: Abstraction simplifies problems by removing unnecessary details and focusing only on the essential characteristics. In programming, this is achieved through functions, allowing for code reuse and simplification, especially in cases with repetitive tasks.

• Modelling: Agent-based models simulate interactions between agents (such as people or objects) to study complex systems. These models are used for making predictions, testing ideas, and solving difficult problems, like predicting the spread of viruses or population growth, leading to better decision-making.

• Heuristics: Heuristics are problem-solving methods that provide quick, adequate solutions, though not always the best. This approach sacrifices accuracy for speed, often used in situations where finding the perfect solution is too time-consuming, like solving the traveling salesman problem.

• Problem Solving: Using computational thinking strategies such as abstraction, pattern matching, and heuristics helps solve complex problems more effectively and efficiently, making it easier to tackle challenges in business and technology.

Important Takeaways from Leaving Certificate Business Studies: Abstraction & Computational Thinking

• Computational Thinking: Computational thinking is a systematic approach to problem-solving. It involves breaking down complex problems into manageable tasks using four main pillars: Abstraction, Pattern Matching, Decomposition, and Algorithms. These strategies are essential for solving business and technological challenges effectively.

• Abstraction: Abstraction simplifies problems by focusing only on the essential details and ignoring unnecessary information. This helps businesses and programmers concentrate on what truly matters, making processes more efficient. Functions in programming are a key example of abstraction, allowing code to be reused and simplified.

• Modelling: Agent-based modelling is a powerful tool for simulating complex systems and predicting outcomes. By studying interactions between agents (such as individuals or businesses), these models help in decision-making, such as predicting virus spread or economic trends, improving the accuracy of business planning and policy.

• Heuristics: Heuristics involves finding quick, sufficient solutions to problems by making educated guesses. While not always precise, heuristics is ideal for situations where time is critical, offering practical solutions without needing to calculate every possible outcome, like in the travelling salesman problem.

• Problem Solving Techniques: Computational thinking, including abstraction and heuristics, equips students with the tools to break down large problems into simpler tasks, recognize patterns, and find efficient solutions. These problem-solving strategies are vital for tackling challenges in business and technology.
