What you will learn
- • Define computational thinking and its key components: decomposition, pattern recognition, abstraction, and algorithms. • Explain the principles of computational thinking, including problem understanding, problem simplification, and solution selection and design. • Describe algorithm design methods, specifically flowcharts and pseudocode, and understand the differences between them. • Create and interpret flowcharts to represent algorithms visually. • Write pseudocode to outline algorithms in a structured, human-readable format. • Engage in algorithmic activities, such as design and evaluation techniques. • Conduct dry runs of flowcharts and pseudocode to manually verify their correctness. • Understand the concept and importance of LARP (Logic of Algorithms for Resolution of Problems). • Implement LARP activities to practice writing algorithms and drawing flowcharts. • Identify different types of errors in algorithms, including syntax errors, logical errors, and runtime errors. • Apply debugging techniques to find and fix errors in algorithms. • Recognize common error messages encountered during LARP and learn how to address them. • Demonstrat
