2.3 Interleaving Flashcards
What is the opposite of interleaved?
Blocked - Practicing A repeatedly, then switching to B, then C, etc.
In “Geometry Study”, what is the task?
Compute volumes for 4 different types of solids
In “Geometry Study”, what is the protocol?
- Training (Blocked vs interleaved)
2. Testing (All interleaved)
In “Geometry Study”, what are the conditions?
2 = blocked + interleaved
In “Geometry Study”, what are you measuring?
Training performance and testing performance
In “Geometry Study”, what are the results?
Practice performance: Blocked is better
Test performance: Interleaved is better
The interleaved group is stable between practice and test. The blocked group goes down in accuracy dramatically
In “Faces and Names study”, what is the task?
Lean fake face and name pairings
In “Faces and Names study”, what is the protocol?
- Training (Blocked vs interleaved)
2. Testing (All interleaved)
In “Faces and Names study”, what are the conditions?
2 = blocked + interleaved
In “Faces and Names study”, what are you measuring?
Training performance and testing performance
In “Faces and Names study”, what are the results?
Acquisition (Training): Blocked is better
Test performance: Interleaved is better
The interleaved group is stable between training and test. The blocked group goes down in accuracy dramatically
In “Complex motor skill study”, what is the task?
Learn complex motor skills, initiating movements on a cue and as fast as possible
In “Complex motor skill study”, what is the protocol?
- Training (Blocked vs Random interleaved)
2. Testing (Blocked vs Random interleaved)
In “Complex motor skill study”, what are the conditions?
2*2 = (2 Training) * (2 Testing)
In “Complex motor skill study”, what are you measuring?
Time, less is better
In “Complex motor skill study”, what are the results?
Training: Blocked is better Testing (From worst to best): B-R [Easy training, difficult test] R-R [Difficult] B-B [Easy] R-B [Difficult training, easy test]
In “Children study”, what is the task?
Learn formulas to calculate the number of faces, edges, corners, and angles on prisms
In “Children study”, what is the protocol?
- Training (Blocked vs interleaved)
2. Testing (All interleaved)
In “Children study”, what are the conditions?
2 = blocked + interleaved
In “Children study”, what are you measuring?
Evolution over time
In “Children study”, what are the results?
Training: Blocked is better
Test performance: Interleaved is better
The interleaved group is stable between training and test. The blocked group goes down in accuracy dramatically
In “Children study”, researchers discovered what 2 types of errors?
- Students using a made up formula that they had NOT learned [A FABRICATION ERROR]
- Students use a valid formula, but they applied it to the wrong task [A DISCRIMINATION ERROR]
In “Children study”, describe the chart on the types of errors
Fabrication errors are low and stable for blocked and interleaved training
Discrimination errors are very high for blocked training, but not for interleaved training
The overall difference between blocked and interleaved training is what? Why?
The number of discrimination errors.
Blocked leads to more since you don’t practice choosing what knowledge to apply
