Selecting the Best: Exploring the Concept of Selection in Computing

Selecting the Best: Exploring the Concept of Selection in Computing

Learning Objective

At the end of the lesson, you will be able to define selection, provide an example of selection in computing, identify similar words to selection, and determine the opposite word to selection.

What do you already know about the concept of selection in computing?

Definition of Selection

Selection is a programming construct that allows a program to make decisions based on certain conditions or criteria.

Example of Selection in Computing

An example of selection in computing is an 'if-else' statement. It allows the program to execute different sets of instructions based on a specific condition.

Similar Words to Selection

Similar words to selection in computing include 'decision', 'choice', and 'condition'.

Opposite Word to Selection

The opposite word to selection in computing is 'repetition'. While selection allows for decision-making, repetition involves executing a set of instructions repeatedly.

Summary

Selection is a programming construct used for decision-making, often implemented through 'if-else' statements. It is important to understand similar words like 'decision' and 'choice' in relation to selection. The opposite of selection is 'repetition', which involves executing instructions repeatedly.

Review Activity

In pairs, come up with three different examples of 'if-else' statements in a programming context.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
