Code Detective: The Art of Debugging

Code Detective: The Art of Debugging

Learning Objective

At the end of the lesson, you will be able to understand and use basic techniques to find and fix mistakes in your computer programs, also known as debugging.

What do you already know about finding and fixing mistakes in computer programs?

What is Debugging?

Debugging is the process of finding and fixing mistakes in computer programs. It's like being a detective and solving puzzles in your code!

Common Mistakes

Mistakes in code can include misspelled words, wrong commands, or forgetting to tell the computer what to do.

Techniques for Debugging

We will learn how to use techniques like reading the code carefully, using trial and error, and seeking help from others to solve problems.

Let's Practice!

Now, let's practice debugging together! We'll have some fun interactive exercises to find and fix mistakes in simple code snippets.

Using Print Statements

One helpful technique is using print statements to check the values of variables at different points in the program.

Working in Pairs

Sometimes, working with a friend can make debugging more fun and effective. You can help each other find mistakes!

Review and Recap

We've learned how to be code detectives and solve mysteries in our programs. Remember, debugging is all about patience and persistence!

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.
