3. Set up computers with Python installed or have an online Python coding environment ready.
4. Ensure all handouts and materials are ready for distribution.

Schedule

Introduction (10 minutes)

1. Welcome and Objectives:

   • Begin with a brief introduction stating the importance of programming in modern careers and technology.
   • Show the lesson objectives on the board.

2. Engage: Evolution of Programming:

   • Present a short history of programming languages from assembly language to present-day Python.
   • Engage students with questions about the devices and software they use daily, leading into the importance of programming.

Direct Instruction (15 minutes)

1. Basics Overview:

   • Discuss the basic concepts: Variables, Data Types, and Control Structures.
   • Write examples on the board.

2. Introduction to Python:

   • Explain why Python is a good starting language (simplicity, readability).
   • Show a brief "Hello, World!" program in Python.

Guided Practice (20 minutes)

1. Hands-on Coding:

   • Distribute handouts with simple Python code examples.
   • Walk students through basic operations like declaring variables, printing output, and simple arithmetic.

2. Interactive Coding:

   • On their computers, have students type out and run these examples.
   • Roam the room to provide help and check understanding.

Collaborative Activity (20 minutes)

1. Pair Programming:
   • Divide students into pairs and give them a small problem to solve (e.g., creating a simple calculator program).
   • Encourage them to discuss their logic and code together.
   • Provide assistance and feedback as needed.

Share and Reflect (10 minutes)

1. Group Discussion:

   • Reconvene and ask each pair to share their solutions and any problems they encountered.
   • Discuss different approaches to the problem.

2. Reflection and Q&A:

   • Ask students to reflect on what they learned and how they might use programming in the future.
   • Open the floor for any questions.

Closing (5 minutes)

1. Recap:

   • Summarize the key points of the lesson.
   • Remind students of the importance of practising and exploring more about programming.

2. Homework Assignment:

   • Assign a simple coding project or online Python tutorial for additional practice.

Assessment

• Formative: Observe students during hands-on coding and pair programming for understanding and active participation.
• Summative: Review the outputs from their simple calculator program and the homework assignment to gauge their comprehension of basic programming concepts.

Extension Activities

For students who understand these basics quickly, encourage them to:

• Explore more complex problems or projects (e.g., simple games, data analysis scripts).
• Investigate other programming languages (JavaScript, Java, C++).
• Participate in coding competitions or online coding communities.

This lesson plan provides a comprehensive and engaging way to introduce 12th-grade students to the basics of programming, ensuring they understand both the conceptual and practical aspects of coding in Python.
