Study Notes

Computational Thinking

  • Computational thinking is a problem-solving approach
  • It's useful for tackling complex problems
  • It involves breaking down problems into smaller parts
  • It uses patterns to solve similar problems
  • It focuses on the essential details of the problem
  • It develops step-by-step solutions

Decomposition

  • Breaking down complex problems into simpler parts
  • Making the problem more manageable and easier to understand
  • Separating the problem into smaller, independent parts
  • Solving each part individually
  • Combining the solutions to the smaller problems to form the overall solution

Pattern Recognition

  • Identifying similarities and patterns in problems
  • Recognizing common characteristics
  • Using similar solutions for similar problems
  • Finding ways to make the problem-solving process more efficient
  • Using patterns to solve problems more easily and quickly

Abstraction

  • Focusing on the important information
  • Ignoring the irrelevant details
  • Creating a general/simplified representation of the problem
  • Identifying the essential characteristics without the extra details
  • Removing unnecessary details in order to simplify and streamline

Algorithm

  • A step-by-step approach to solve a problem
  • A set of instructions that clearly define how to solve a problem
  • Instructions must be followed in a specified order
  • Provides a clear and organised method to solve problems
  • This ensures all steps are followed accurately

Flowcharts

  • Diagrams representing a set of instructions for solving a problem
  • Uses standard symbols to represent different instructions
  • Can be broken into many steps for providing a detailed explanation
  • Can be simplified to show steps that happen in fewer steps
  • They are used to create a visual representation of instructions.

Pseudocode

  • A simple method for outlining instructions
  • Not limited to specific language
  • Steps are written on a single line and in sequence
  • Instructions are written in uppercase
  • Variables/values in lowercase, messages in sentence case
  • INPUT asks a question, OUTPUT prints a message on the screen

Looping

  • When a statement executes in a loop until a specific state/condition is reached
  • Loops continually repeat until a condition/state is false
  • Makes programming more efficient

Testing

  • A crucial step in any problem-solving process
  • Involves trying out your solution
  • Identifying any problems encountered during the testing and making changes/improvements
