The Concept Attainment Model is a teaching strategy used to help students develop concepts and understand relationships between ideas. In this case, the teacher is using the model to develop the concept of "Force".

Key Characteristics:

The examples provided by the teacher illustrate key characteristics of the Concept Attainment Model:

• Positive examples: The teacher provides examples that demonstrate the concept of force, such as pulling a chair, stopping a moving ball, and pushing a desk.

• Negative examples: Although not explicitly mentioned, the teacher might also provide examples that do not demonstrate force, such as a stationary object or an object moving without any external influence.

• Analysis and comparison: The teacher encourages students to analyze and compare the examples to identify the common underlying concept of force.

Concept Development:

By presenting these examples, the teacher is helping students develop an understanding of the concept of force, including:

• Cause-and-effect relationships: Students see how forces can cause objects to move or change direction.

• Types of forces: Students are introduced to different types of forces, such as pulling and pushing.

• Real-world applications: The examples illustrate how forces are present in everyday life, making the concept more relatable and accessible.
