Error Identification and Correction

Overview

Age Group: Entry Level 1 (typically learners aged 5-7 or with equivalent learning needs)
Class Size: 8 students
Duration: 45 minutes
Unit: Tech Task Mastery (Lesson 6 of 7)
Subject: Technology

Curriculum Links

This lesson maps to the National Curriculum for England Computing programmes of study, Key Stage 1 (Years 1 and 2), with adaptations for Entry Level 1 students' needs:

Computing - Key Stage 1
Understand what algorithms are; how they are implemented as programs on digital devices; and that programs execute by following precise and unambiguous instructions
(NC Reference: Programing and problem solving)
Use technology safely and respectfully
Identify simple errors and problems and know strategies for solving them
(NC Reference: Online safety and problem-solving)
Development Matters (Early Years Foundations Stage/EL1)
Use teaching focused on developing understanding and vocabulary around simple problem-solving

Learning Objectives

By the end of this lesson, students will be able to:

Identify simple errors in their completed digital tasks and describe what went wrong.
Demonstrate basic strategies for troubleshooting errors in technology tasks (e.g., checking steps, trying again, asking for help).
Reflect orally on how correcting errors improved their work, developing resilience and persistence skills.

Resources Needed

Tablets or laptops with simple drag-and-drop programming apps (e.g., Espresso Coding, Bee-Bot simulators, or ScratchJr)
Printouts of students’ completed projects/tasks or screenshots for reference
Visual error cards illustrating common problems (e.g., “Code won’t run,” “Wrong output,” “Frozen screen”)
“Troubleshooting Steps” poster with simple icons and keywords: Look, Think, Try, Ask
Whiteboard and markers
Stickers or stamps for positive reinforcement

Lesson Structure

1. Introduction and Recap (5 minutes)

Welcome and settle students.
Briefly recap previous lesson: “Last time, we created tech tasks on our devices. Did anyone have things that didn’t work quite right?”
Show a simple example of a task with an error (e.g., a robot that didn’t move in the right direction).
Link to today’s goal: “Today, we are problem solvers — learning how to find and fix mistakes in our work!”

2. Modelling Error Identification (10 minutes)

Show a prepared digital task on the projector/screen with deliberate errors.
Talk through spotting the error: “I see the robot didn’t move forward, why? Oh, it was missing a step!”
Explain the importance of careful checking ("debugging").
Use the “Troubleshooting Steps” poster: Look (at your work), Think (what could be wrong?), Try (fix it), Ask (for help if stuck).
Engage students by asking for their observations and ideas.

3. Guided Group Activity: Spot and Fix (15 minutes)

Distribute tablets/laptops with students’ own completed tasks or similar examples.
Students work in pairs with support to:
- Identify any errors or unexpected results.
- Use the poster steps to try simple fixes (e.g., adding a missing command, trying again).
Teacher circulates to scaffold and encourage reflective thinking: “What did you notice? What can you try next?”
Use visual error cards to aid recognition and language development.

4. Sharing and Reflecting (10 minutes)

Gather as a whole group. Invite a few pairs to share:
- What error did they find?
- How did they fix it?
- How did it feel to solve the problem?
Reinforce positive attitudes towards mistakes as learning opportunities.
Affirm persistence with praise and stickers/stamps.

5. Summary and Next Steps (5 minutes)

Recap key message: "Mistakes help us learn! Checking carefully and trying again makes us confident tech users."
Briefly introduce the last lesson in the unit (Lesson 7): applying what we’ve learned to create a complete task independently.
End with a fun “tech detective” hand signal to celebrate problem-solving success today.

Assessment and Evaluation

Formative Assessment:
- Observation of students identifying errors and explaining them during paired work and group discussion.
- Use of questioning to assess understanding of troubleshooting steps.
Peer and Self-Assessment:
- Verbal reflection on fixing errors promotes metacognition appropriate to Entry Level 1.
Teacher Notes:
- Keep anecdotal records of individual student progress and confidence with error detection.
- Adjust support in final lesson based on students’ troubleshooting abilities today.

Differentiation and Inclusion

Provide one-to-one adult support for students needing more help.
Use visual aids and simple language consistently.
Group mixed-ability pairs to encourage peer learning.
For non-verbal students, use alternative communication methods (e.g., gesture cards, pointing to error cards).
Allow extended time or breaks where needed.

WOW Factor: Creative Engagement Idea

"Tech Detective Badges"
Create simple paper badges or stickers for students, titled “Tech Detective,” awarded during the lesson when they successfully identify and correct an error. This gamifies troubleshooting and builds a positive identity as resilient problem solvers early in their technology use journey.

This plan brings practical troubleshooting into the curriculum in an accessible, supportive way for Entry Level 1, closely aligned with the National Curriculum for Computing, promoting foundational digital literacy and problem-solving skills in young learners.
