Mastering Flowcharts: Learning the Art of Selection

Mastering Flowcharts: Learning the Art of Selection

Learning Objective

At the end of the lesson, you will be able to understand and create flowcharts to represent decision-making processes.

What do you already know about flowcharts and their use in decision-making?

Slide 1: Introduction to Flowcharts

Flowcharts are visual representations of processes or algorithms. They use different symbols to represent different actions or decisions.

Slide 2: Symbols and Meanings

Symbols like rectangles, diamonds, and arrows are used in flowcharts. Rectangles represent processes, diamonds represent decisions, and arrows show the flow of control.

Slide 3: Basic Structure of a Flowchart

A flowchart typically starts with a 'start' symbol, followed by various steps or decisions, and ends with an 'end' symbol.

Slide 4: Flowchart Example - Ordering Process

Let's analyze a flowchart representing an ordering process and understand how decisions are made at each step.

Slide 5: Decision-Making in Flowcharts

Decisions in flowcharts are represented by diamonds. Each decision has two or more possible outcomes, which lead to different paths in the flowchart.

Slide 6: Conditional Statements

Conditional statements like 'if-else' or 'switch' can be used within flowcharts to handle complex decision-making scenarios.

Slide 7: Practice Exercise

Now it's time for you to create a flowchart to represent a decision-making process of your choice. Use the symbols and concepts we've learned so far.

Slide 8: Conclusion

Congratulations! You have learned the basics of flowcharts and how they are used in decision-making. Keep practicing and exploring different scenarios to enhance your skills.

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.
