### Lesson Plan: System Development Cycle
**Grade Level:** Senior Secondary 2
**Subject:** Data Processing
**Topic:** System Development Cycle
**Duration:** 70 minutes
**Objectives:**
1. To understand the concept and importance of the System Development Cycle (SDC).
2. To identify and describe the phases of the SDC.
3. To analyze how each phase interrelates to complete the system development process.
**Materials Needed:**
- Whiteboard and markers
- Projector and laptop (for slides)
- Printed handouts of the SDC phases
- Sample case study handout
- Notebooks and pens
**Lesson Outline:**
**Introduction (10 minutes):**
1. **Greeting and Roll Call:** Quick check-in with students.
2. **Warm-Up Question:** "Can you think of a situation in your life where you needed to plan out steps to achieve a goal?"
3. **Introduce Topic:** Briefly introduce the concept of the System Development Cycle and its relevance in data processing and software development.
**Presentation (30 minutes):**
1. **Explanation of SDC:**
- Definition: Explain what the System Development Cycle is.
- Importance: Discuss why it is essential in creating efficient and reliable systems.
2. **Phases of the System Development Cycle:**
- **Planning:** Discuss how the problem is identified, feasibility studies are conducted, and project plans are developed.
- **Analysis:** The process of examining what the system needs to do by gathering detailed requirements from stakeholders.
- **Design:** Outlining the system architecture, data models, and user interfaces.
- **Implementation:** The phase where actual coding, development of databases, and system integration occur.
- **Testing:** Conducting various tests (unit, system, integration, user acceptance) to ensure the system functions as intended.
- **Deployment:** The system is put into production for use by all intended users.
- **Maintenance:** Ongoing updates, debugging, and system monitoring to ensure continued performance.
3. **Visual Aid:** Use slides to visually depict each stage. Show how these phases connect and build on each other.
**Activity (15 minutes):**
1. **Case Study Analysis:**
- Hand out a brief case study of a simple project (e.g., developing a website for a school's event management system).
- Break the class into small groups.
- Each group must identify and explain how they would apply each phase of the SDC to the case study.
**Group Presentations (10 minutes):**
1. Each group presents their case study analysis.
2. Peers and teacher provide feedback.
**Conclusion (5 minutes):**
1. **Recap:** Summarize the key points of the lesson.
2. **Q&A:** Open the floor for any final questions.
3. **Assignment:** Students should write an individual reflection on how they would apply the System Development Cycle to a personal project or a hypothetical scenario.
**Assessment:**
- Participation in the discussion and group activity.
- Presentation of the case study analysis.
- Quality of individual reflection submission.
**Follow-Up:**
- Review individual assignments.
- Plan additional exercises or projects to deepen understanding of System Development Cycle in practical contexts.
End the session by acknowledging students' efforts and encouraging them to think critically about how systematic planning can be applied in various aspects of their lives.
