Week & Period: Week 22, Period 4
Topic: Injuries
Sub-topic: Learning Objectives
By the end of the lesson, students should be able to:
- Identify different types of joints: fixed, hinge, ball-and-socket, pivot, and saddle.
- Explain how joint structure affects susceptibility to injuries.
- Recognize common joint injuries and relate them to local physical activities.
Previous Knowledge
Students already know:
• Basic anatomy of the skeletal system
• Types of minor and major injuries
Instructional Materials
• Textbook: Physical Education textbooks for Grade 9
• Teaching aids:
• Students' notebooks and writing materials
• Diagrams or models of joints
• Space for safe practical simulations
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Activity: The teacher will ask the class:
• Can you name some joints in your body?
• Have you ever experienced a joint injury during sports or daily activities?
The teacher will record responses on the board.
Teacher’s Role: Facilitate discussion, clarify misconceptions, and connect prior knowledge to new content.
Learner’s Role:
• Share experiences and ideas about joints and injuries.
• Participate in identifying joints on diagrams or peers.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Teacher’s Role:
The teacher introduces the types of joints:
- Fixed joints (immovable): found in the skull; provide protection and stability.
- Hinge joints: found in the elbow and knee; allow movement in one plane (flexion and extension).
- Ball-and-socket joints: found in the shoulder and hip; allow multi-directional movement and rotation.
- Pivot joints: found in the neck (atlas and axis); allow rotational movement.
- Saddle joints: found in the thumb; allow angular motion and grasping.
The teacher explains the function of each joint and its range of motion, highlighting how structural differences influence susceptibility to injuries. Examples include knee sprains (hinge joint), shoulder dislocations (ball-and-socket), and wrist strains (saddle joint).
The teacher relates joint function and injury risk to local physical activities, including Liberian traditional games, sports, farming tasks, and dancing.
Learners’ Activities (Expanded):
- Observe joint diagrams or 3D models and label each type accurately.
- Simulate movements for each joint: bending the elbow/knee, rotating the neck, swinging the arm or leg, thumb opposition, to understand functionality.
- Identify joints involved in local sports and traditional activities (e.g., shoulder and elbow in throwing games, hip in dances).
- Discuss real-life cases of joint injuries, analyzing causes and preventive measures.
Assessment Checks:
- Observe learners performing joint movement exercises correctly and safely.
- Ask learners to match joint types with common injuries and explain why they occur.
- Conduct Q&A to assess understanding of joint structure, motion, and injury vulnerability.
Notes (Expanded & Detailed):
- Emphasize the relationship between joint structure, range of motion, and susceptibility to injury.
- Highlight culturally relevant examples, such as shoulder and knee involvement in football, dances, or farming activities.
- Stress the importance of safe movement, warming up, and strengthening surrounding muscles to protect joints.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary:
• The teacher will ask students to recall joint types, their functions, and common injuries.
Evaluation Method (Expanded):
• Exit slip/quiz: Students write short answers to:
- Name the five types of joints.
- Describe one common injury for a ball-and-socket joint.
- Explain how joint structure can influence injury risk.
Teacher provides oral feedback and clarifies misconceptions.
Assignment (Expanded):
Follow-up Activity:
• Observe a local sports or dance session and note which joints are most used and the risk of injuries.
Differentiation / Inclusive Strategies
• Struggling Learners: Use additional diagrams, peer demonstrations, and guided practice.
• Advanced Learners: Research and present on rare joint injuries or advanced preventive techniques.
• Students with Disabilities: Adapt joint movement simulations to ensure safe participation.
