Introduction: Computational Thinking and Programming (Unit D)

Introduction​

This module introduces students to computational thinking and programming concepts that are fundamental to computer science and problem-solving. Students will learn to think algorithmically, design solutions to problems, and implement these solutions using programming languages. This module develops logical thinking, creativity, and technical skills essential for the digital age.

Learning Objectives​

Students will learn about:

  • the principles of computational thinking, including decomposition, pattern recognition, abstraction, and algorithms;
  • fundamental programming concepts such as variables, data types, control structures, and functions;
  • how to design and represent algorithms using flowcharts and pseudocode;
  • how to write, test, and debug simple programs in a programming language; and
  • the importance of program documentation and maintenance.

Module Structure πŸ—ΊοΈβ€‹

This module is divided into several key areas to ensure a comprehensive understanding:

  1. Computational Thinking: Core concepts and problem-solving strategies.
  2. Algorithm Design: Representing solutions using flowcharts and pseudocode.
  3. Programming Fundamentals: Variables, data types, operators, and expressions.
  4. Control Structures: Sequence, selection (if/else), and iteration (loops).
  5. Modular Programming: Functions and procedures for organized code.
  6. Program Development Cycle: Planning, coding, testing, and debugging.

Key Concepts to Master πŸ’‘β€‹

  • Algorithm: A step-by-step procedure to solve a problem.
  • Flowchart: Visual representation of an algorithm.
  • Pseudocode: Text-based representation of an algorithm.
  • Variable: A named storage location for data.
  • Loop: Repeating a block of code.
  • Conditional Statement: Executing code based on a condition.
