When helping students debug their code, one of the most effective things you can do is simply be there with them. Sitting next to a student and asking them to explain their code can be incredibly helpful. This process allows them to review what they’ve written and potentially spot any errors themselves. Your presence is important, but it can be challenging to give individual attention to every student in a busy classroom.
Another useful strategy is to direct students to focus on a specific part of their code. You might say something like, “Take a look at these four or five lines of code. I’ll check in with other students and come back to you. If you haven’t figured it out by then, we can work through it together.” This approach gives them time to think and can lead to productive problem-solving.
When students express confusion, such as saying, “I don’t know what to do,” try asking, “Where are you stuck? At what point?” This encourages them to walk you through their code, which can help both of you identify issues. Sometimes, another student might even notice the error and offer assistance.
It’s important to create a classroom environment where making mistakes is seen as a natural part of learning, especially in computer science. Encourage students to understand that errors are normal and that working through them can lead to a strong sense of achievement.
One feature of code.org that is particularly helpful for debugging is the ability to switch between block and text modes. Some students, especially those with previous coding experience, might prefer text mode and feel unsure about using blocks. However, blocks are excellent for helping students understand the structure of their code. They are especially useful when working with loops and conditional statements. The color-coded blocks help students visualize relationships in their code and identify logical errors, such as forgetting to close a loop or including unnecessary elements.
By being present, encouraging focused problem-solving, and fostering a positive attitude towards mistakes, teachers can greatly assist students in learning to debug their code. Utilizing tools like code.org can further enhance this learning process by providing visual aids that make understanding code structure easier.
Pair up with a classmate and take turns explaining your code to each other. As you explain, try to identify any errors or areas of confusion. This will help you practice articulating your thought process and may lead to discovering solutions together.
Select a small section of your code that isn’t working as expected. Spend 10 minutes analyzing just those lines. Write down any observations or questions you have. Afterward, discuss your findings with a partner or the teacher to gain new insights.
Keep a journal where you document each time you encounter a bug. Write down what the bug was, how you identified it, and the steps you took to fix it. Reflecting on these experiences will help you develop better debugging strategies over time.
Once a week, have a session where you share a mistake you made in your code and how you resolved it. Celebrate these mistakes as learning opportunities. This will help you and your classmates view errors as a natural and valuable part of the learning process.
Use code.org to experiment with switching between block and text modes. Try solving the same problem using both modes and note the differences in how you approach the task. Discuss with your classmates which mode you find more intuitive and why.

When it comes to debugging in the classroom, the best thing you can do is to be present with the student. If you can sit next to them, you don’t even have to say much—just ask them to talk through their code. This gives them a chance to review what they wrote and see if they can identify any errors or mistakes. Being there for them is crucial, but in a classroom setting, that can be challenging.
Another approach is to provide them with a specific focus. You might say, “I’d like you to look at these four or five lines of code. I’m going to check in with some other students, and I’ll come back to you. If you haven’t figured it out by then, we can work through it together.” Giving them that time can be very productive.
Here are some helpful phrases to use when coaching students: When they say, “I don’t know what to do,” you can ask, “Where are you stuck? At what point?” This encourages them to walk you through their code, and you may notice things that you hadn’t seen before. Sometimes, another student might even point out where the error is.
It’s also important to foster a classroom culture that embraces mistakes. Make sure students understand that it’s okay to make mistakes; it’s a normal part of learning, especially in computer science. The process of making mistakes, troubleshooting, and ultimately finding solutions can lead to a great sense of accomplishment.
One feature I appreciate about code.org for debugging is the ability to switch between block and text modes. Some students, particularly those with prior coding experience, may prefer text mode and feel hesitant about using blocks. However, blocks can be very effective for helping students understand the structure of their code, especially when working with loops and conditional statements. The color-coded blocks allow them to visualize the relationships in their code and identify logical errors, such as not properly closing a loop or including unnecessary elements.
