[Lesson Report] Introduction to System Development Week 17 – Final Presentations & Reflection

In Week 17, our concluding session featured final app presentations and a comprehensive course reflection.

■ Instructor’s Opening: “Show Us the Culmination of This Semester”

Mr. Tanaka:

“Everyone, recall what you’ve learned these past six months and share your development成果 with pride. Focus on the joy of presenting rather than nerves!”

■ Presentation Round ①: App Demos & Highlights

Each team took the stage to demonstrate their original app, explaining usage, design decisions, and development challenges.

• Omikuji (Fortune‐teller) App Team
  “We focused on robust error handling for unexpected inputs and styling the results display.”
• Personality Test App Team
  “By fine‐tuning our scoring algorithm for each question, we improved result accuracy significantly.”
• Branching Story App Team
  “We centralized all navigation logic in a single function to manage user‐choice transitions.”

Applause and questions from classmates made for a lively atmosphere.

■ Presentation Round ②: Hands-On Testing & Q&A

After each demo, classmates took the role of users to test the app live and asked questions:

• “How did you implement the back-button functionality?”
• “Where do you handle empty-input validation?”
• “How did you organize your code files?”

Teams shared design diagrams and code snippets on screen, providing detailed answers.

■ Whole-Class Reflection: Sharing Our Learnings

Following the presentations, we reflected on the semester as a class. Each student filled out a worksheet and paired up to discuss:

• Skill I grew in the most
• My favorite lesson topic
• What I want to explore next

Student A:

“I never imagined I’d go from the first robot-command activity to building a complete app!”

Student B:

“Debugging sessions taught me the most—it’s where I learned to think like a developer.”

■ Instructor’s Closing Remarks

“You’ve all worked incredibly hard. Programming is ‘making thought visible.’ I hope today you felt the joy of communicating your ideas through code. Next term, we’ll tackle API integrations and generative AI—let’s level up together!”

■ Course Completion & Next Steps

This concludes our first-year “Introduction to System Development” course. Next term, we’ll dive into:

• External Service Integrations (e.g., weather and map APIs)
• Building Simple Chatbots with Gen-AI
• Team Development Exercises

Carry your accomplishments forward and shine in the next stage of your learning journey!
