Advance Programming II SS3 Plan

LESSON PLAN: ADVANCED PROGRAMMING II

Subject:	Digital Technologies
Class:	SSS 3
Term:	First Term
Week:	3
Topic:	Advanced Programming II
Duration:	80 Minutes (Double Period)
Subtopics:	Object-Oriented Programming (OOP), classes and objects, attributes and methods, encapsulation, inheritance, polymorphism and abstraction.

1. BEHAVIOURAL OBJECTIVES

By the end of the lesson, students should be able to:

1. Define Object-Oriented Programming (OOP).
2. Explain the meaning of classes and objects.
3. Identify attributes and methods in a class.
4. Explain the basic principles of OOP.
5. Write a simple program using a class and an object.
6. State practical applications of object-oriented programming.

2. INSTRUCTIONAL / TEACHING AIDS

• Computer system or laptop.
• Projector or interactive display, where available.
• Python programming environment or an online Python interpreter.
• Whiteboard and markers.
• Prepared examples of classes, objects, attributes and methods.

3. PREVIOUS KNOWLEDGE / ENTRY BEHAVIOUR

Students have previously learnt about functions, parameters, return values, arrays and lists. The teacher asks students to explain what a function does and how it can be used to organise a program.

4. PRESENTATION STEPS

STEP	TEACHER'S ACTIVITY	STUDENTS' ACTIVITY
Step 1: Introduction (10 minutes)	Reviews functions and asks students how a program might represent real-world things such as students, cars or bank accounts. Introduces OOP as a programming approach that organises data and behaviour into objects.	Respond to questions and give examples of real-world objects and their characteristics.
Step 2: Classes and Objects (15 minutes)	Explains that a class is a blueprint for creating objects, while an object is an instance of a class. Uses a Student class as an example and identifies attributes and methods.	Define a class and an object and identify possible attributes and methods of a student object.
Step 3: Practical Demonstration (20 minutes)	Demonstrates how to define a simple Python class, use the __init__() method to initialise attributes, create an object and call a method.	Observe the demonstration, identify the class and object, and practise writing or tracing the example.
Step 4: Principles of OOP (20 minutes)	Explains encapsulation, inheritance, polymorphism and abstraction using simple, familiar examples.	Explain each principle in their own words and suggest examples of how it may be used in a program.
Step 5: Applications and Class Activity (10 minutes)	Discusses applications of OOP in school management systems, banking software, games and business applications. Guides students in designing a simple class.	Design a class with at least two attributes and one method, such as a Book or Student class.
Step 6: Conclusion (5 minutes)	Summarises the meaning of OOP, classes, objects and the four basic principles. Corrects misconceptions and gives an assignment.	Answer oral questions and record the assignment.

5. EVALUATION QUESTIONS

1. What is Object-Oriented Programming?
2. Differentiate between a class and an object.
3. What are attributes and methods?
4. List and explain the four basic principles of OOP.
5. Write a simple Python class with two attributes and one method.

6. ASSIGNMENT

1. Explain the meaning of a class and an object with two examples each.
2. Describe encapsulation, inheritance, polymorphism and abstraction.
3. Write a Python program that defines a Student class with a student's name and age as attributes and a method that displays the student's details.
4. State four applications of Object-Oriented Programming.

7. TEACHER'S REFLECTION

After the lesson, the teacher should reflect on the following:

• Were students able to distinguish between classes and objects?
• Could students identify attributes and methods correctly?
• Were students able to explain the four principles of OOP?
• Could students create a simple class and object independently?
• What areas require further explanation or practical revision?
