### Lesson Outline:
#### Introduction (10 minutes)
1. **Greeting and Attendance**:
- Welcome students and take attendance.
2. **Introduction to the Topic**:
- Briefly introduce the topic of Program Development.
- Explain the relevance of program development in data processing and software engineering.
#### Direct Instruction (20 minutes)
1. **Definition and Overview**:
- Define "Program Development".
- Discuss the role of program development in creating reliable and efficient software.
2. **Stages of Program Development**:
- **Planning**: Identifying the purpose and requirements.
- **Analysis**: Detailed study of user needs and system requirements.
- **Design**: Creation of algorithms, flowcharts, and structure.
- **Implementation**: Writing the actual code.
- **Testing**: Debugging and validating the program.
- **Maintenance**: Updating and refining the program based on user feedback and other factors.
3. **Real-World Example**:
- Display a simple real-world problem and discuss how it can be approached through each stage of program development.
#### Guided Practice (15 minutes)
1. **Group Activity**:
- Divide the class into small groups.
- Provide each group with a problem statement (e.g., creating a simple calculator program).
- Encourage them to brainstorm and briefly discuss the steps they would take in each stage of program development.
2. **Discussion**:
- Have each group present their ideas.
- Provide constructive feedback and highlight any key points they may have missed.
#### Independent Practice (10 minutes)
1. **Individual Task**:
- Ask students to write down a different simple problem and outline the steps they would take to develop a program for that problem.
- Encourage them to use the stages discussed.
#### Closing (5 minutes)
1. **Review and Recap**:
- Summarize the key points of the lesson.
- Reinforce the importance of each stage in program development.
2. **Q&A**:
- Open the floor for any questions or clarifications.
3. **Assignment**:
- Assign a homework project where students must develop a comprehensive plan for a small program, including flowcharts or pseudocode.
#### Assessment:
- Evaluate the group activity to see how well students understood and applied the stages of program development.
- Review individual tasks to assess their grasp of the planning and analysis stages.
- Use the homework assignment to evaluate their ability to design and outline a program independently.
#### Differentiation:
- Provide additional support and simpler problems for students who may struggle with the concepts.
- Offer more complex problems and encourage the creation of more detailed flowcharts for advanced students.

### Homework:
- Develop a comprehensive plan for a small program (e.g., a basic to-do list app or a simple game). Include detailed algorithms, flowcharts, or pseudocode for each stage of development. Aim to present their work in a future class session.

### Reflection:
- After the lesson, reflect on what went well and what could be improved. Note any adjustments needed for future lessons on program development.
This lesson plan aims to equip Senior Secondary 2 students with a solid understanding of program development, preparing them for more intricate studies and projects in data processing and software development.
