1. 1 Chapter 3 Motor Development: A Theoretical Model © Gallahue, D.L., & Ozmun, J.C.. Understanding Motor Development. McGraw-Hill

2. 2 Key Concept Motor Development May Be Conceptualized, Using an Hourglass Heuristic, As a Discontinuous and Overlapping Phase-stage Process

3. 3 The “Bottom Line”: Development of Movement Competence (i.e., skillful movers) Motor control Movement coordination

4. 4 Motor Control and Movement Coordination Is Influenced By: Positive factors (“affordances”) Negative factors (“constraints”) …Occurring within the movement task, the biology of the individual, and the conditions of the learning environment

5. 5 Dynamic Systems Theory Views Development As a Process That Is : Multifaceted Nonlinear Discontinuous Transactional Self-organizing

6. 6 As a Discontinuous Process, Motor Development Is Controlled by The: Requirements of the movement task Biology of the individual Conditions of the learning environment

7. 7 Phase/stage Theory Views Motor Development As a Product That: Progresses from simple to complex Is sequential and orderly in nature Builds skill upon skill Requires proficiency in basic skills prior to using them as complex skill Varies in rate and extent from person to person

8. 8 The Phases of Motor Development Reflexive Movement Phase Rudimentary Movement Phase Fundamental Movement Phase Specialized Movement Phase

9. 9 The Hourglass Heuristic (Figure 3.1) Conceptualizing development (figure 3.2) -As a process -As a product Dynamical aspects (T.I.E) The overturned hourglass (figure 3.3) -Hereditary filter -Lifestyle filter -Lifelong opportunities for learning

10. 10 Concluding Concept Understanding the Process and Products of Motor Development Helps Explain How Movement Skill Learning Occurs, Which Is Crucial to Developmentally Appropriate Instruction
