How Motor Development, Motor Learning and Biomechanics Relate to Effective Teaching

Teaching Keys

Teaching keys should direct the mover to the correct form of the movement, moving through a logical progression toward a more proficient movement.

Teaching keys should direct the mover to proper positions throughout the movement to enhance the process (form) and protect the body from undue stresses.

Teaching keys should consider: •How the force for the movement is created •How balance is created for the movement •How the direction of the movement can be controlled •How body parts are aligned and move dynamically around each other•What constitutes the unique rhythm of body parts moving in concert with each other

Developmental sequences of movement are available to guide many of the basic movements and shape the teaching keys needed to move a child to a more proficient movement form

How can we modify movement to allow a child to practice a movement at an appropriate level?

Set task goals to elicit the movements you want to occur

Choose interesting equipment that fits the child’s size and strength that will allow the child to complete the desired task goals.

Appropriate feedback should be based on teaching keys which correct the errors while moving the child to a higher proficiency. How can we organize practice for the best chance of learning the skill?

Can we use other equipment such as this mat to frame a more meaningful target context for amovement practice?

How do we create the force for this movement? What is the force sequence (beginning to end)? What has to strengthen to allow this movement?

What parts are moving forcefully? What issues of dynamic balance are created by the force? How is this movement (force) counterbalanced to allow the body to continue moving?

Aiming of the movement affects the direction of both ballistic and locomotor skills

How do we create the correct positioning of the body for biomechanical efficiency and joint safety by the language we use in our teaching keys and the demonstrations we provide?

For this beginning thrower, what is an appropriate choices of ball and task definition to create the best possible practice? What teaching keys would you emphasize to correct this movement?

What throwing implement would be most effective for this child? Should we include another skill like catching with the movement? How can this child create more force to throw harder or longer? What alignment of body parts will create the best throw? When and how can this child move to a more proficient movement form?

Side to the target Prepare to exert force with shoulder turn Direction of throw relative to target Arm way back Preparation to create force and aiming Step with the opposite foot Begins the exertion of the force sequence Step toward target for aiming Lengthens base of support to recreate balance Follow through to target Completion of force and aiming

Biomechanics

Learning and using appropriate movement forms maintains the integrity of joints

Example Using Teaching Keys for Throwing

For this beginning striker, what is an appropriate choice of bat and a good task definition to create the best possible practice? What teaching keys would you emphasize to correct this movement?

What characteristics should the bat have to be effective for this task? Lightweight for lesser arm strength? Smaller grip for smaller hands? Large batting surface for better chance of contact with the ball? Batting surface closer to the hands?

UNDER HAND SERVEis easy to do but is not used often except by the youngest players. It is preferable because it allows easier and fuller participation for more students and has better alignment, preventing injuries.

OVERHEAD SERVE is simple and effective but often more difficult for younger players to accomplish. It also opens them up to misalignment and therefore, injury.

JUMP SERVE is aggressive, sophisticated and complex. Players need to be more advanced to achieve this with correct alignment to maintain the integrity of the elbow and shoulder joints.

Rhythm

Alignment

Proper alignment of body parts provides the opportunity to move While maintaining joint integrity.

Every movement has sits own unique rhythm that shapes the task. Learning the rhythm makes the task flow more efficiently.

How do we create the correct positioning of the body for biomechanical efficiency and joint safety by the language we use in our teaching keys and the demonstrations we provide?

Example:Practice the approach, takeoff, contact and landing in the volleyball spike.

When using the Whole-Part-Whole planning strategy, after showing the whole skill, break it down into individual parts or practice trials.

Example Begin with a light

ball and then increase the weight of the ball in volleyball set.

Change equipment to make the skill more age appropriate. Younger children’s motor skills are not fully developed, they need simpler or lighter equipment.

Change the net height and boundaries of the court or field to make the game more successful.

Example: In a chasing game decrease the

space to make it harder for the tagger

Example Practice underhand

serve to increase playing success. Or overhead serve if your opponents use that serving style.

Changing the goal could simplify or complicate the outcome of the game. You can modify for the skill level of your students.

Example Practice dance steps

first by yourself and then with a partner.

Adding or decreasing the amount of people changes the tactics involved in playing the game.

Example: If you are having

trouble getting the ball over the net, take a few steps in front of the service line.

Most sports are complex, by taking out an element of a game, it makes it easier for students to grasp, rather than throwing them into the whole sport automatically.

Example: You can use as

many hits as you need to get the ball over the net.

Changing rules allows for more successful attempts.

9 vs. 9 volleyball in Japan

Example Practice shooting in

basketball, then practice dribbling and shooting.

Develops game-like situations where two or more skills will have to be combined.

Example Design 3 exercises to increase back

flexibility.

It helps students apply what they have learned.

Application is a higher level of learning and will reinforce memory and relationships.

and Students

Thinking about technology vs natural physical activity (Wii)◦ Video games, computers and

smart TVs vs. meaningful movement experiences. Adolescent Growth, Maturation

and Development (Siedentop, 1994)

◦ How Adolescents Learn – The millennium generation

View technology and physical activity as a spectrum on a continuum (not as natural opposites).

Including students with disabilities and late mature students.

Presentation of content and reviews.

Modeling as critical demonstrators.

Teaching concepts as powerful tool.

Direct teaching, personalized system of instruction or an inquiry based approach into teaching sports? Why not?

Effective and reflective teaching

Teaching with expertise in mind

Teaching styles in physical education:

Mosston’s Spectrum

◦ Pedagogical knowledge

◦ Sociological knowledge

◦ Cultural knowledge

Developmentally appropriate practice

Creating a positive learning environment

Scientific knowledge base using a research based approach

(NASPE, 1992b; NASPE 2009)

Pedagogical continuum: sequence and scope

Skill analysis (observation and technology) Prescription of learning progression Teaching strategies (individualization) Equipment use: effectiveness and safety. Understanding tasks and learners

(feedback) How to teach plus “why”

◦ reasoning, rationale Flow, enjoyment and fun!

“Physical Education can provide a strong foundation for our school from which all education can rise.”

George Leonard, 1974

“We need each other to enlighten ourselves.”
