## Grade Level: Senior Secondary 2
### Subject: Data Processing
**Duration**: 60 minutes
---
**Lesson Objectives**:
By the end of the lesson, students will be able to:
1. Define what a computer file is.
2. Identify and explain different types of computer files.
3. Understand the file structure and file management.
4. Explain file extensions and their importance.
5. Perform basic file operations such as creating, renaming, deleting, and moving files.
### Materials Needed:
- Computer with internet access
- Projector/Smartboard
- Whiteboard and markers
- Notebooks and pens
- Sample files in different formats (text, image, audio, etc.)
### Lesson Outline:
#### Introduction (10 minutes)
- **Hook**: Begin with a quick activity. Show students a variety of real-world objects (e.g., books, documents, photos) and ask them to identify what these objects would translate to in the digital world.
- **Discussion**: Relate the objects to files on a computer, introducing the concept of computer files.
#### Direct Instruction (20 minutes)
- **Definition and Importance**:
- A computer file is a collection of data or information that is stored on a computer.
- Files are essential for storing documents, images, programs, and more.
- **Types of Computer Files**:
- **Text files** (e.g., .txt, .docx)
- **Image files** (e.g., .jpg, .png)
- **Audio files** (e.g., .mp3, .wav)
- **Video files** (e.g., .mp4, .avi)
- **Executable files** (e.g., .exe, .bat)
- **File Structure and Management**:
- Explain folders/directories and their purpose.
- Hierarchical structure of files.
- **File Extensions**:
- Explain what file extensions are: .txt, .jpg, .mp3, etc.
- Importance of file extensions in identifying file types.
#### Guided Practice (15 minutes)
- **Activity**:
- Show students how to create different types of files using a computer.
- Demonstrate renaming, deleting, and moving files.
- Use sample files to show how file extensions work.
#### Independent Practice (10 minutes)
- **Exercise**:
- Give students a list of tasks to perform on their computers:
1. Create a text file and name it "MyNotes.txt".
2. Create a folder named "MyFiles".
3. Move "MyNotes.txt" to "MyFiles" folder.
4. Rename "MyNotes.txt" to "ClassNotes.txt".
5. Delete the "ClassNotes.txt" file.
- Walk around the classroom to assist and ensure each student is on track.
#### Closing (5 minutes)
- **Review and Recap**:
- Summarize the key points covered in the lesson.
- Ask a few students to share what they have learned about computer files.
- **Homework**:
- Assign students to create a short report (1-2 pages) on how they use different types of files in their daily lives.
### Assessment:
- **Formative**: Monitor students’ participation during the activities and practice sessions.
- **Summative**: Evaluate the homework report for understanding of concepts covered in the lesson.
### Accommodation and Differentiation:
- Provide step-by-step printed instructions for students who need additional support.
- Allow advanced students to explore more complex file operations, such as file compression and extraction.
### Reflection:
- After the lesson, reflect on what went well and what can be improved.
- Gather feedback from students to make necessary adjustments for future lessons.
