what is computational thinking used for

to study a problem and formulate an effective solution

what is abstraction

extracting information and only including what is necessary to solve that problem

what is in computational thinking

abstraction, decomposition, pattern recognition

what do you need to keep in mind in abstraction

purpose and information

what is decomposition

process of breaking a complex problem into smaller parts until a smallest unit is found

what is used for decomposition

flowcharts, structure diagrams

what is pattern recognition

identification of parts of a problem and could use the same solution

what are algorithms

ordered set of steps to be followed

what is structured english

using an agreed subset of straightforward english words

what is a flowchart

diagrammatic representation of an algorithm

what is pseudocode

using keywords, identifiers, meaningful names, mathematical operators

what is stepwise refinment

subdividing each part of a larger problem into a series of smaller parts
