Digital Literacy, Problem Solving
Lesson Goal
By the end of this lesson, learners should be able to apply different file naming conventions appropriately to name files and folders in a way that supports efficient digital organisation and retrieval.
Rationale
This lesson introduces learners to the fundamental skill of using different file naming conventions, building on their prior knowledge of creating and saving files from earlier ICT lessons. Understanding how to name files systematically is essential for learners in urban Zambian contexts, such as managing school assignments, personal documents, or project files at a community ICT centre, as it promotes order, saves time, and reduces frustration when locating digital content. Through hands-on naming activities, pair discussions, and real-world scenario tasks, this competence-based lesson actively develops learners' Digital Literacy and Problem Solving skills by engaging them in authentic file management challenges that require logical thinking and informed decision-making.
Prior Knowledge / Prerequisite Knowledge
Learners already know how to create, open, and save files using common applications such as a word processor or simple graphics program, and they can identify basic file types (e.g., document, image, audio) by their icons. They also understand the concept of a folder as a container for files. This prior knowledge will be activated at the start of the lesson when the teacher presents a cluttered folder of unnamed files and asks learners to predict the contents, thereby creating a meaningful bridge to the new content on systematic file naming conventions.
Learning Environment
- Natural Environment: The teacher draws on learners' everyday experiences in urban Zambian settings such as Lusaka's markets, bus stations, or school libraries where labelling and organising are essential. For example, the teacher may reference how a market vendor labels price tags or how a school librarian arranges books on shelves to connect the idea of naming conventions to real-world organisation.
- Artificial Environment: The classroom is arranged in a whole-class setup with desks in a U-shape to allow clear visibility of the demonstration board and to facilitate pair work. A large wall chart titled "Rules for Naming Files" is displayed at the front, and a pocket chart with sample file cards is placed on the side board for interactive sorting activities during the lesson.
- Technological Environment: The teacher uses a single laptop or desktop computer connected to a projector to demonstrate file naming conventions in real time. A pre-prepared folder containing sample files (e.g., "Report.docx", "Photo.jpg", "Song.mp3") is used to show naming examples. If a projector is unavailable, the teacher uses printed screen captures displayed on a large chart.
Teaching and Learning Materials / Resources
- A set of 20 printed file cards (each showing a generic file name such as "doc1", "pic2", "letter") for sorting activities
- Two large manila charts: one titled "File Naming Rules" and the other titled "Good vs Poor File Names"
- Marker pens (blue, black, red) and masking tape
- A pre-prepared folder on a laptop with 10 sample files of different types (document, image, spreadsheet, audio) saved with both meaningful and meaningless names
- Printed worksheets for the Explore and Elaborate phases (one per pair)
- A4 blank paper cut into small cards for learners to write their own file names during pair activities
- A magnetic board or felt board with name-card magnets for demonstration
Cross-Cutting Issues
- Education For Sustainable Development: This lesson promotes sustainable digital practices by teaching learners to organise digital files systematically, which reduces frustration and wasted time when locating documents. By adopting clear naming conventions, learners develop a lifelong habit of efficient digital resource management that supports sustainable learning and work practices in urban Zambian schools and beyond.
- Entrepreneurship Education: The ability to manage digital files using consistent naming conventions is directly applicable to entrepreneurial activities such as keeping records of business documents, customer invoices, or project proposals. Throughout the lesson, learners encounter scenarios drawn from small-business contexts in Lusaka, such as organising receipts, contracts, and marketing materials, thereby linking file management skills to future entrepreneurial success.

ENGAGE
12 min |
- Hook: "Imagine you are helping your elder sibling at their small shop in Matero, Lusaka. They have ten different documents on their phone — receipts, supplier lists, price tags, and customer orders — all saved with names like 'doc1', 'doc2', 'doc3'. They need to find the price list quickly but cannot. Why is this a problem? What could help? Turn to your neighbour and share one idea."
- Prior Knowledge Questions: "What do we call a container that holds files on a computer?" (Expected: folder or directory.) "When you save a file for the first time, what must you type in the 'File name' box?" "What are some different types of files you have saved before — for example, a .docx or .jpg — and how do you tell them apart?"
- Lesson Goal: "Today we are going to learn how to use different file naming conventions so that we can name files and folders in a clear, organised way. By the end of this lesson, you will be able to choose a meaningful and appropriate name for any file or folder you create."
- Note: Do NOT introduce the new concept yet — this phase is purely about igniting curiosity and surfacing prior knowledge.
|
- Learners listen to the hook scenario and discuss one idea with a partner, sharing their thoughts about why file names matter. (Develops: Collaboration, Communication)
- Learners answer prior knowledge questions by raising hands and giving examples of folders, file types, and their own experiences with saving files. (Develops: Communication, Digital Literacy)
- Learners listen to and then paraphrase the lesson goal in their own words when invited by the teacher. (Develops: Communication)
- Learners ask questions or share personal examples of times they could not find a file on a computer or phone. (Develops: Critical Thinking)
|
- Learners confidently discuss at least one reason why meaningful file names are important.
- Learners accurately recall the term 'folder' and correctly name at least two different file types.
- Learners clearly restate the lesson goal in simple language.
- Learners logically connect the hook scenario to their own experiences with digital file organisation.

EXPLORE
17 min |
- Learning Activities: The core activity for this phase is "Naming files and folders". Learners will work in pairs to sort and name a set of file cards.
- Investigation Setup: "In your pairs, you will receive an envelope containing ten file cards. Each card shows a file type (e.g., 'School Report', 'Sports Day Photo', 'Music Song', 'Maths Homework'). Your task is to discuss and write an appropriate file name for each card on the blank label provided. Follow these three rules: (1) the name should tell you what the file contains, (2) use only letters, numbers, underscores, or hyphens — no spaces or special characters like * or ?, and (3) include the correct extension at the end, such as .docx, .jpg, .mp3, or .xlsx. You have 10 minutes to complete this activity. I will walk around and listen to your ideas."
- Facilitation: Walk around among pairs without lecturing. Ask guiding questions such as: "Why did you choose that particular word in your file name?" "How does adding the date help someone find this file later?" "What might happen if you used a space in this file name?"
- Observation: Note which pairs are confidently applying naming rules and which pairs need guidance on avoiding spaces or special characters.
|
- Learners read the instructions on the worksheet and begin working in pairs to open their envelope of file cards. (Develops: Collaboration, Digital Literacy)
- Learners discuss each file card with their partner and write a meaningful file name on the blank label, including the correct extension. (Develops: Problem Solving, Collaboration)
- Learners compare their chosen names with those of a neighbouring pair and discuss any differences. (Develops: Communication, Critical Thinking)
- Learners record their final list of ten file names in their exercise books for later reference. (Develops: Digital Literacy, Organisation)
|
- Learners accurately follow the investigation instructions and begin the sorting activity within one minute.
- Learners correctly write at least eight out of ten file names using appropriate conventions (no spaces, meaningful words, correct extensions).
- Learners clearly explain at least one difference they noticed when comparing names with another pair.
- Learners independently record their final list of file names legibly in their exercise books.

EXPLAIN
17 min |
- Learner Sharing: Invite 2–3 pairs to share one example of a file name they created. Ask: "What name did you choose for the 'School Report' card, and why?" Write selected examples on the board.
- Formalisation: "Let us now learn the formal rules for file naming conventions. A file name has two parts: the base name and the extension, separated by a dot. For example, in 'Maths_Homework.docx', the base name is 'Maths_Homework' and the extension is '.docx' which tells us it is a Word document. The rules are: (1) use only letters, numbers, underscores (_), and hyphens (-); (2) NEVER use spaces, slashes, or special characters like *, ?, <, >, |; (3) keep names short but meaningful; (4) use the correct extension for the file type; and (5) be consistent — use the same style every time." Display the wall chart summarising these rules.
- Worked Example: "Watch as I name a file. I have a photo from the school athletics day held on 15 June 2025. I will name it 'Athletics_Day_2025-06-15.jpg'. Notice I used underscores instead of spaces, I included the date in year-month-day format, and I added the correct extension .jpg for a photo. Now I will save it in my 'Sports' folder." Write the example step by step on the board.
- Guided Questions: (1) MCQ — "Which of the following is a valid file name? A. My Report.docx, B. My_Report.docx, C. My*Report.docx, D. My/Report.docx" (2) Fill-in-the-Blank — "A file name consists of a base name and an ________ separated by a dot." (3) Short Answer — "Why should we avoid using spaces in file names?" Build on learner responses to clarify each point.

- New Task: "You are helping a friend who runs a small bakery in Kamwala, Lusaka. She has the following digital files on her computer that need to be organised and renamed: (1) a recipe for bread, (2) a list of daily sales for March 2025, (3) a photo of the new cake design, (4) a customer feedback form, and (5) a poster for an upcoming promotion. Your task is to create a folder for the bakery and then write appropriate file names for each of these five files using the conventions we have learned. Also write one sentence explaining why you chose each name."
- Instructions: "Work with your partner. On the worksheet provided, draw a folder icon at the top and label it 'Kamwala_Bakery'. Then list each file with its new name and explanation. You have 12 minutes. Remember to use underscores, correct extensions, and meaningful names."
- Facilitation: Walk around, observe, and offer probing questions only — not answers. Ask: "How does adding the month help organise the sales file?" "What extension would you use for the poster file?" "Is there a consistent pattern you can apply across all five files?"
- Extension: For gifted and talented learners: "Imagine the bakery also has files from three different years (2023, 2024, 2025). How would you organise the folder structure and naming to make it easy to find any file from any year? Write your plan as a diagram."

- Consolidation Questions: (1) "What are the two parts of a file name? Give an example." (2) "Why is it a bad idea to use spaces in a file name?" (3) "Imagine you have three homework files: one for English, one for Maths, and one for Science, all from Term 1 of 2025. Write one model file name for each on your mini whiteboard or scrap paper, following the conventions we learned."
- Learner-Led Summary: "In your own words, summarise the most important thing you learned today about file naming conventions. Who would like to share?" Invite 2–3 learners to speak. Affirm correct points and gently correct any lingering misconceptions.
- Link Forward: "Next lesson, we will learn how to organise files into folders and subfolders to create a clear digital filing system — something that will help you keep all your school projects tidy throughout the term."
- Homework: "Go home and look at the files on your family's phone or computer. Find three files that have poor or meaningless names. In your exercise book, write the original name, then write an improved name using the conventions we learned today. For example, 'doc1.docx' could become 'Chores_List_2025.docx'. This is due tomorrow at the start of class."
- Closure: "Well done, everyone! Today you learned a valuable digital skill that will save you time and frustration. Keep practising your file naming — you are now better organised than many adults! Thank you for your hard work."

Class Exercise
Instructions to learners: Answer all five questions in your exercise book. Show all working where applicable. Time allowed: 10 minutes.
- Multiple Choice: Which of the following is a valid file name that follows correct naming conventions?
A. My Holiday Photo.jpg
B. My_Holiday_Photo.jpg
C. My*Holiday*Photo.jpg
D. My Holiday/Photo.jpg
- Fill-in-the-Blank: A file name consists of two parts separated by a dot: the base name and the ________.
- Short Answer: List three characters or symbols that are NOT allowed in a file name and explain why they should be avoided.
- True or False: Writing "Report_Final.docx" is a better file name than "Report.docx" because it is more descriptive. Provide one sentence to justify your answer.
- Application (Scenario): A Form 1 learner at a school in Ndola has saved all their term assignments in one folder with these names: "aa.docx", "bb.docx", "cc.docx", "dd.docx". Analyse this situation: (a) Identify two problems the learner will face when trying to find a specific assignment. (b) Suggest a better file naming convention the learner should use, and write an example name for an English composition titled "My Best Holiday" from Term 1 of 2025.
Answer Key (For Teacher Use Only)
-
Question 1 — Multiple Choice
Answer: B. My_Holiday_Photo.jpg
Marks: 1 mark for correct letter and full option.
-
Question 2 — Fill-in-the-Blank
Answer: extension (or file extension)
Marks: 1 mark for the correct word.
-
Question 3 — Short Answer
Answer: Learners should list any three from: space ( ), asterisk (*), question mark (?), slash (/), backslash (\), colon (:), less than (<), greater than (>), pipe (|), quotation mark ("). Explanation: These characters can cause errors in file systems because they are reserved for special purposes or can corrupt the file path. Accept any reasonable justification.
Marks: 3 marks — 1 mark for each correctly listed character with a valid explanation.
-
Question 4 — True or False
Answer: True. Justification: "Report_Final.docx" is more descriptive because it tells the user that this is the final version, whereas "Report.docx" could refer to any draft or version. Accept any similar logical justification.
Marks: 2 marks — 1 mark for "True" and 1 mark for a clear, logical justification sentence.
-
Question 5 — Application (Scenario)
Answer: (a) Problems: (i) The learner cannot tell which file is which without opening each one — the names give no clue about the content. (ii) If the learner needs a specific assignment (e.g., the Science report), they have to open every file to find it, wasting time. Accept other reasonable problems. (b) Suggested convention: Use meaningful names with underscores and include the subject, assignment title, and term. Example name: "English_My_Best_Holiday_T1_2025.docx". Accept any valid name that follows conventions.
Marks: 4 marks — 2 marks for identifying two distinct problems (1 mark each), 1 mark for suggesting a clear naming convention, 1 mark for writing a correct example name.
Total Marks: 11 |
Suggested Completion Time: 10 minutes
