SOLO Levels: Uni-structural & Multi-structural (Click to view)
Uni-structural: Focus on one relevant part of the task (e.g., naming one step in a process).
Multi-structural: Identifying several relevant aspects independently (e.g., listing all steps but not how they interact).
Jigsaw Method (Surface)
d = 0.92
Definition: Students master sub-topics in expert groups and teach them to home groups.
Example: In a science unit on animal types, each group learns about one class (Mammals, Reptiles, etc.) to share with the home group.
Outlining and Organizing
d = 0.84
Definition: Structuring information into a logical, hierarchical format to prioritize key ideas.
Example: 4th graders use a graphic organizer to list the main characters and setting before reading a new story.
Repeated Reading
d = 0.80
Definition: Reading a text multiple times to improve fluency, accuracy, and basic comprehension.
Example: 3rd graders practice reading a short poem aloud three times to improve their speed and expression.
Vocabulary Programs
d = 0.65
Definition: Explicit instruction of word meanings and roots to build foundational knowledge.
Example: 5th graders use a Frayer Model to define "biodiversity," listing its characteristics and drawing an example.
Spaced Practice
d = 0.62
Definition: Distributing study sessions over days or weeks rather than cramming.
Example: 6th graders review history dates for 5 minutes every Tuesday and Thursday for a month.
Retrieval Practice
d = 0.49
Definition: Actively recalling information from memory through low-stakes testing.
Example: Students take a quick, ungraded quiz at the start of class to remember yesterday's science lesson.
