Code Review and Pair Programming

Active learning builds teamwork and problem-solving skills in Year 8 Technologies. Students practice real-world software development habits through structured collaboration, improving both code quality and communication. Moving beyond theory, they learn to catch errors early and share expertise in ways that stick long after the lesson ends.

Activity 01

• Peer Teaching
• 30 min · Pairs

Pair Programming Challenge: Simple Algorithm

Pairs select a task like sorting a list in Python. One acts as driver coding while the other navigates with suggestions; switch roles after 5 minutes. Pairs test and debug together, then share one key learning with the class.

Justify the benefits of code reviews for improving software quality and team learning.

Facilitation Tip

For the Pair Programming Challenge, circulate and quietly note which pairs struggle with role balance so you can offer targeted reminders about switching every three minutes.

What to look for

Students are given a short, intentionally flawed code snippet. In pairs, they conduct a mini code review, identifying at least two specific issues and suggesting improvements. They then swap their feedback with another pair and provide one piece of constructive feedback on the feedback itself.

Activity 02

• Peer Teaching
• 45 min · Small Groups

Code Review Carousel: Bug Hunt

Print or share 4-5 code snippets with common errors. Small groups rotate every 7 minutes to review one snippet, list 3 issues and 2 improvements, then discuss as a class.

Explain how pair programming can lead to more robust and efficient code.

Facilitation Tip

During the Code Review Carousel, provide magnifying glasses or zoom tools so students can examine tiny logic errors in printed snippets without missing details.

What to look for

Pose the question: 'What is one benefit of having a second person review your code before it's finished?' Students write a one-sentence answer on a sticky note and place it on a designated board as they leave the class.

Activity 03

• Peer Teaching
• 40 min · Whole Class

Feedback Rounds: Project Snippets

Students submit short code from prior work. In a whole class circle, each pair presents one snippet for 2-minute reviews from two peers, noting strengths and fixes.

Critique a piece of code, providing constructive feedback for improvement.

Facilitation Tip

In Feedback Rounds, supply colored pens so reviewers can highlight code while giving comments; this makes feedback visible and easier to discuss.

What to look for

Facilitate a class discussion using the prompt: 'Imagine you are leading a small team on a project. How would you implement pair programming and code reviews to ensure the best outcome? What challenges might you anticipate?' Encourage students to share practical strategies and potential solutions.

Role-Switch Relay: Game Logic

Pairs build game logic step-by-step, switching driver/navigator every 3 minutes. After 15 minutes, pairs swap with another to review and refine the code.

Justify the benefits of code reviews for improving software quality and team learning.

Facilitation Tip

For the Role-Switch Relay, use a timer on the board so students see the pace of switching and avoid domination by one partner.

A few notes on teaching this unit

Teach pair programming as a habit, not just a task. Model switching roles yourself during live coding so students see the value of both thinking and typing. Keep feedback focused on one improvement at a time to avoid overwhelming beginners. Research shows that structured switching reduces dominance and increases learning for both partners.

Students will demonstrate improved code by spotting issues and suggesting fixes in pairs. They will explain how peer input strengthens design and logic, and they will switch roles confidently to keep both partners engaged. Clear, constructive feedback becomes second nature during every activity.

Watch Out for These Misconceptions

• During Pair Programming Challenge, students think the driver’s role is more important than the navigator’s.

  Pause the activity after two minutes and ask drivers to share one thing the navigator caught that they missed. This redirects focus to the navigator’s role in catching logic and efficiency flaws.

• During Code Review Carousel, students assume code reviews only find syntax errors like missing semicolons.

  Point to the printed snippets and ask students to circle any design choices that make the code harder to understand or extend. Discuss alternatives aloud as a class to show that reviews cover logic, efficiency, and readability.

• During Role-Switch Relay, students believe solo coding is faster because they haven’t experienced the long-term benefits of pair work.

  Bring out a timer and record how long it takes pairs to complete the task versus solo attempts. Debrief by asking how many errors the pair found that a solo coder might have missed.
