Sometimes, the challenge of taking a high-stakes test is less about the content itself and more about a student’s ability to access the content and manage the cognitive demands while doing so. Today, we will explore three research-supported strategies that help students strengthen and organize their long-term memory during test preparation and focus their limited working memory capacity during testing. Helping students strategize in ways that work with their brains—and regulate their stress responses—can be the difference-maker in improving test performance.
Strategy 1: The Power of the Brain Dump
Instead of encouraging students to reread their notes or class slides to study for a test, leverage the power of retrieval practice. Research shows that retrieving information from memory strengthens memory pathways more effectively than rereading and helps students perform better on complex tasks.
The Strategy:
- Encourage students to do a “Memory Dump” on a blank sheet of paper (or digital equivalent) for 5 minutes before they even look at their review materials. The only prompt needed is the content topic or unit title.
- Then have students pull out their review material to fact-check their brain dump. Have them correct any misunderstandings and then highlight or underline to color-code their recalled information:
- Green: Things they remembered instantly (representing a high level of fluency)
- Yellow: Things they remember after a few minutes of thinking (representing developing fluency)
- Red: Key information they knew they needed to remember but couldn’t recall until checking notes or slides (representing the “gap” areas)
- Students now have a clear path for studying:
- They do not need to review the green information.
- They can then turn the yellow information into flashcards for further review. Consider using Quizlet (reviewed here) or Cram (reviewed here) for digital options. Cram offers various review modes, including self-paced learning and spaced repetition, in which information is revisited at varying intervals.
- Students focus their study time on the red information, potentially using Strategy 2 below to help solidify understanding.
The Research Tie-In: Retrieval practice pushes students to actively produce answers rather than simply recognizing correct ones. Research highlights that retrieval practice greatly benefits long-term memory. In particular, spaced retrieval practice, such as a cumulative review “Memory Dump,” produces “desirable difficulty” because recall occurs long after the initial period of learning and forgetting. Research also suggests that retrieval practice can protect against the effects of acute stress, such as a high-stakes testing environment, on memory inhibition.

Strategy 2: Connect the Dots with Concept Mapping
Concept mapping can be a powerful tool for connecting prior knowledge with new learning. It involves using nodes to represent central concepts and links between nodes to represent relationships among them. In cumulative test review, concept mapping serves both as a creative form of retrieval practice and as a way to leverage elaborative interrogation—asking how and why concepts work or are similar/different.
The Strategy Flow:
- Provide students with a list of the semester/year’s big ideas that will serve as anchor nodes. Students can build their concept maps on paper or digitally; consider Canva (reviewed here) mind map templates, Figjam (reviewed here) for a collaborative option, or Diagramo (reviewed here) for a simple, no-account-needed option.
- Ask students to spend 10 minutes mapping from memory only to initiate retrieval practice.
- Then ask students to spend 5 minutes filling in the gaps using their textbook, notes, or other review materials. Consider having students use a different color for this information to make knowledge gaps visible and help them focus future study.
- Push students to write linking verbs on the connecting lines to define the relationships rather than just acknowledging them. Finding cross-links between content taught at different times will help with Strategy 3 on the test day.
When students spend time organizing information into a hierarchy, they move beyond memorizing isolated facts and begin building an organized mental filing system, ready for retrieval on test day.
But even when knowledge is well-organized, students must still manage the cognitive demands of accessing and applying it under pressure—especially in a testing environment. This is where Strategy 3 becomes critical.
The Research Tie-In: As noted in Chapter 3 of Smart Teaching, Stronger Learning, research consistently shows that concept mapping leads to better performance than more traditional study methods, such as discussion or reading summaries. Further, students who construct concept maps outperform those who simply read them. The use of linking words combines elaboration with retrieval practice, strengthening later recall.
Strategy 3: Practicing “Offloading” on Practice Tests
Cognitive Load Theory, developed by John Sweller, suggests that our working memory has limited bandwidth. Test anxiety can increase extraneous load, leaving little room for actual problem-solving. Cumulative review practice sets or tests provide an opportunity to simulate testing conditions and intentionally regulate cognitive load.
The Strategy:
- Students can “offload” any high-stakes formulas, acronyms, or dates onto scratch paper or test margins before starting. For students who regularly engage in retrieval practice, this serves as a short-form brain dump, conserving cognitive resources for the higher-level thinking required to apply the recalled information to the test questions.
- Encourage students to flag or note questions they feel stuck on. Rather than staying stuck, shifting that content to a diffuse mode of thinking allows them to continue making progress. Other questions may help trigger recall of the “stuck” material by connecting it to a big idea or by recognizing similarities or differences between two concepts.
The Research Tie-In: Reducing extraneous cognitive load is critical for performance, particularly for students who struggle with executive function skills such as prioritization and time management. Research by Sian Beilock and colleagues indicates that anxiety can be a source of additional cognitive load and rob students of their working memory capacity. Starting with a brain dump builds confidence and helps students enter focus mode. When students flag and move on from difficult questions, they remain productive on new tasks while the brain continues processing the “stuck” problem in the background—referred to as diffuse mode thinking in Barbara Oakley’s Learning How to Learn.
By shifting from passive study strategies to active, brain-based approaches—such as retrieval practice, concept mapping, and cognitive offloading—we can empower students to approach high-stakes testing with greater confidence and less anxiety. These strategies do more than improve test scores; they help students organize their learning in ways that support long-term retention and mastery.
