Computer Science Fundamentals Unit 5 Course D Lesson 4: Debugging with Laurel (2018)

Subject Area

Digital Literacy and Computer Science

Grade(s)

3

Overview

In this online activity, students will practice debugging in the "collector" environment. Students will get to practice reading and editing code to fix puzzles with simple algorithms, loops, and nested loops.

The purpose of this lesson is to teach students that failure is normal when learning a new skill. Students will be given pre-written programs that do NOT work. They will be asked to fix these programs. This process, called "debugging", teaches students essential problem solving and critical thinking skills. These skills transfer over as students proceed to harder and harder programming projects.

Students will be able to:
- read and comprehend the given code.
- identify a bug and the problems it causes in a program.
- describe and implement a plan to debug a program.
