How it works. Retrieval practice asks a student to recall an idea, definition, process, or formula from memory before checking the answer. The effort of retrieving information helps make later recall more reliable.

In a lesson: I might ask short questions, have the student explain a process from memory, or give a few questions without notes before reviewing what they missed.

Especially useful for: vocabulary, formulas, facts, concepts, and test preparation.

How it works. Instead of studying the same material for hours in one sitting, students return to it over multiple sessions. Forgetting some of the material between sessions makes each retrieval more meaningful.

In a lesson: I can identify the most important material and build quick review cycles into future sessions so earlier concepts stay accessible.

Especially useful for: languages, definitions, formulas, science concepts, and cumulative classes.

How it works. Rather than completing twenty nearly identical problems in a row, interleaving mixes different types of problems. The student must first identify what kind of problem they are facing and then choose a strategy.

In a lesson: I can combine several related skills once the student understands each one individually.

Especially useful for: mathematics, science, grammar, and other subjects with multiple problem-solving methods.

How it works. Students explain their reasoning rather than only stating an answer. Explaining why a rule applies or why a step works can reveal gaps that a correct answer may hide.

In a lesson: I can ask questions such as “Why does that work?” or “How did you know which method to use?” and help refine the explanation.

Especially useful for: math, science, reading comprehension, grammar, coding, and problem solving.

How it works. Students answer questions before seeing the solution and then use the results to identify what needs more attention. Testing yourself can strengthen retrieval while also exposing weak areas.

In a lesson: I can use short, low-stakes question sets, then explain missed questions and target the underlying concept.

Especially useful for: quizzes, tests, exams, standardized-test preparation, and cumulative review.

How it works. Dual coding combines verbal explanations with useful visuals such as diagrams, timelines, labeled models, or simple sketches. The visual should clarify the idea rather than simply decorate the page.

In a lesson: I can turn a difficult process or relationship into a diagram and then connect each visual element back to the written explanation.

Especially useful for: science, history, geography, processes, systems, and conceptual material.

How it works. A worked example shows the steps of solving a new type of problem. As the student becomes more comfortable, support is gradually removed until they can solve the problem independently.

In a lesson: I can demonstrate a process, ask the student to complete selected steps, and then move toward independent problems.

Especially useful for: mathematics, science, grammar, and coding fundamentals.

How it works. Instead of simply correcting a wrong answer, we identify the type of error: a missing concept, incorrect method, skipped step, misunderstanding, or careless mistake. The student then practices the specific weakness.

In a lesson: I can review missed questions and help the student build a clear pattern for recognizing and avoiding the same error.

Especially useful for: math, science, grammar, test preparation, and any subject where the same mistakes keep appearing.
