Variable Practice
• Enhances development of schema | back 1 - Does NOT always lead to greater performance,
|
front 2
Variable practice guidelines
– How to implement variability | back 2 -
Variations in regulatory, non-regulatory conditions
-
Depends on
closed or open skills, inter-trial
variability -
Create challenges to assess progress
|
front 3
Variable practice guidelines
- When to implement variability | back 3 -
After basic movement pattern has been learned
|
| back 4 -
Switching from one skill to another
-
Changing the context in which a task is practiced
from trial to trial
|
front 5
Contextual Interference
Blocked practice (low contextual interf.) | back 5 -
One skill or variation is practiced at a
time
- EX. 10 minutes each of passing, dribbling,
shooting with no overlap
-
leads to short-term performance gains
|
front 6
Contextual Interference
Random practice (high contextual interf.) | back 6 - Skills organized with none rehearsed twice in a
row
-
leads to long-term performance gains
|
front 7
Contextual Interference Effect
Working memory | back 7 -
stimulation houses multiple tasks
-
Allows for distinctions to be formulated
|
front 8
Contextual Interference Effect
temporary forgetting | back 8 -
Causes temporary forgetting of task solutions between
trials
- Regeneration of task solution required
|
front 9
Contextual Interference Application | back 9 - Nature of task
- Task variations governed by the same
generalized
motor program - Parameter modifications
elicit interference effect
- Learner characteristics: age,
skill level
- Serial practice
|
front 10
Contextual Interference Application
• Nature of task | back 10 -
Task variations governed by the same
generalized motor program
-
Parameter modifications elicit
interference effect
|
front 11
Contextual Interference Application
• Learner characteristics: age, skill level | back 11 -
Blocked practice => for children, novices
|
front 12
Contextual Interference Application
• Serial practice | back 12 - used to create moderate contextual
interference
-
Combination of blocked and random practice
- Def.) a set of sequence of trials is
practiced
repeatedly (ex. repeated blocked practice)

Contextual Interference Application
Challenge point framework | back 17 -
Optimal amount of info must be available for
learning to occur
-
Info: function of skill level and task
difficulty
|
front 18
Contextual Interference Application
Systematic increases in contextual interference facilitates learning | back 18 -
Environmental difficulty increases with skill
level
|
front 19 Contextual Interference Application
Self-regulated practice | back 19 -
Learners control own practice schedule
-
Increases contextual interference
|
front 20
Contextual Interference Implications | back 20 -
Blocked practice @early stages
-
Serial, repeated-blocked, random schedules
-
Don’t allow
- complete breakdown of movement
pattern
-
Be aware
|
front 21
Contextual Interference Implications
Serial, repeated-blocked, random schedules (combining multiple
skills + skill variations) | back 21 -
Different serve locations,
- forehand/backhand practice
-
Vary incline, direction, speed of movement
-
Multiple objects with different sizes,
textures
|
front 22
Practice Distribution
• Massed practice | back 22 -
Rest time between sessions < practice time
|
front 23
Practice Distribution
• Distributed practice | back 23 -
Rest time between sessions = OR > practice time
- more/equal rest with practice time
- Fosters great development of learning
|
front 24
Practice Distribution
• Learning advantage for... | back 24 - shorter, more frequent sessions
|
front 25
Practice Distribution
• Continuous skills | |
front 26
Practice Distribution
• Discrete skills | |
| |
front 28
Practical Implications
Distributed practice avoids... | back 28 -
high levels of fatigue
- Fatigue
introduces incorrect motor patterns, AND increases injury
risk
|
front 29
Practical Implications
• Greater rest periods for... | back 29 - new/complex skills
- high-energy continuous tasks
|
front 30
Practical Implications
• Technique should be taught first when... | |
front 31
Practical Implications
• Massed practice good for... | back 31 -
higher skill
-
leads to game like physical conditioning
|
| back 32 - Rest intervals
- Equipment substitutions
- Drill
design
|
front 33
Maximizing Time on Task
• Rest intervals | back 33 -
Fill with another activity that promotes learning,
contextual interference
|
front 34
Maximizing Time on Task
• Equipment substitutions | back 34 -
Be creative to keep everyone active
-
Don’t allow substitute to change movement
pattern
|
front 35
Maximizing Time on Task
• Drill design | back 35 -
Directly target a learning goal
-
Include all learners
