- Reference Materials
The following resources were used in planning this lesson:
- 9 – Years Basic Education Curriculum
- Abuja Educational Resource Centre Scheme of work
- NAPPS National Unified Scheme of Work
- Online Information From Chtips – What Are The Different Types Of Floppy Disk In Computer System?
- Relevant Textbooks
Instructional Materials
The teacher will teach this lesson with the aid of:
- Visual aids of different types of diskettes
- Actual floppy diskettes (if available)
- Charts showing the sizes and densities of diskettes
- Computer or projector for showing images and videos
Rationale for the Lesson
Understanding the types and differences between diskettes helps pupils appreciate the evolution of storage devices, which is crucial for understanding modern technology. It also builds a foundation for further studies in computer science and technology.
Prerequisite/Previous Knowledge
Pupils should have prior knowledge of what a floppy disk is and its basic functions from the previous lesson.
Learning Area: Types of Diskette
To deliver this lesson, the teacher will adopt the following steps:
| Content Development | Time | Teaching Method | Teaching Strategy | Teacher’s Activity | Pupils’ Activity | Learning Point |
|---|---|---|---|---|---|---|
| Step 1: Introduction | 5 mins | Discussion | Engaging pupils with questions | Ask pupils what they remember about floppy disks from the previous lesson | Respond to questions | Recall previous lesson content |
| Step 2: Explanation of Diskette Types | 10 mins | Lecture | Using visual aids | Show different types of diskettes and explain their features | Observe and ask questions | Understanding different diskette types |
| Step 3: Describing Diskette Densities and Grades | 10 mins | Demonstration | Using charts and actual diskettes | Demonstrate and explain different densities and grades of diskettes | Participate in demonstration | Differentiation of densities and grades |
| Step 4: Hands-on Activity | 5 mins | Interactive | Group activity | Organize pupils into groups to examine diskettes | Examine and discuss in groups | Practical understanding of diskettes |
| Step 5: Note Taking | 5 mins | Lecture | Guided note-taking | Guide pupils in writing notes about the lesson | Copy notes | Reinforce learning through writing |
| Step 6: Evaluation | 3 mins | Q&A | Interactive questioning | Ask questions to evaluate understanding | Answer questions | Assess understanding of lesson objectives |
| Step 7: Conclusion | 2 mins | Summary | Summarize key points | Recap the main points of the lesson | Listen and reflect | Reinforce key learning points |
Lesson Content:
Types of Diskette
There are different types of diskettes used over time. The main types include:
- 8-inch Diskette: This was the first type of floppy diskette. It could store around 80KB of data. It is very large and was mainly used in the 1970s.
- 5.25-inch Diskette: This diskette is smaller than the 8-inch version and can store more data, usually between 360KB and 1.2MB. It was commonly used in the 1980s.
- 3.5-inch Diskette: This is the most recent and widely recognized floppy disk. It can store up to 1.44MB of data. It has a hard plastic cover which makes it more durable.
Densities of Diskettes:
- Single Density (SD): These have the least storage capacity.
- Double Density (DD): These can store twice as much data as single density.
- High Density (HD): These have even greater storage capacity, up to 1.44MB.
Lesson Evaluation
To evaluate the learning, the teacher asks pupils to:
- Identify the three main types of floppy diskettes.
- Describe the differences between the 5.25-inch and 3.5-inch diskettes.
- Explain what is meant by single density, double density, and high density.
- Discuss with a partner which type of diskette they think is the best and why.
Note for teachers using my lesson plan:
Hi there, remember that I didn’t make this lesson plan with any particular class or teacher in mind and I tried as much as possible with my experience and expertise to deliver this plan in a standard and effective style utilizing the best strategy and methods. Nevertheless, you are free to customize the lesson content, teaching methods, timing and pupil activities to suit your teaching style, pupils comprehension, curriculum, and resources available to you. Happy teaching!
