Computational Thinking and Algorithms

Start with the core terms

The flashcard deck “Computing revision” introduces terms including algorithm, decomposition, abstraction, input, processing and output. It also includes linear and binary search, and merge and bubble sort. Start by going through the terms, then return to the cards you find harder to explain.

The “Computer Science Revision” flashcards offer another way to study abstraction, decomposition, pseudocode and variables. Comparing the wording in the decks can help you practice explaining a term in your own words.

Use a map alongside the cards

The “Computing” mind map brings computational thinking, algorithms, decomposition and abstraction together. It describes an algorithm as a set of steps for completing a task and decomposition as breaking a problem into smaller problems. Look at the map after studying the flashcards and follow the connections between those ideas.

You can also use the “Cards” flashcard deck to go over terms such as pattern recognition, flowchart, program and pseudocode. Try explaining where each term fits before checking the card. Return to the mind map when you want to see the core concepts together again.

Move on to practice

The page also lists “Computing revision quiz”. After working through the flashcards and mind map, use it as another way to check your understanding. If a question brings up an unfamiliar term, go back to a relevant card or map before continuing.

For more on algorithms, the “computing” flashcards include flowchart symbols, pseudocode and algorithm efficiency. The “Ch. 1-2 Quiz” flashcard deck covers terms including sequential, conditional and iterative operations.

Explore the wider unit

This topic is a section of the unit “Introduction to Computing, ICT and its History” in Computing and ICT (programming, computer science, digital skills, educational technology). Its cards, maps and quiz give you different ways to work with the computational thinking and algorithm concepts collected in that section.

Choose a flashcard deck to begin, then pair it with a mind map.
