I blog on Brain-Based Learning, Metacognition, EdTech, and Social-Emotional Learning. I am the author of the Crush School Series of Books, which help students understand how their brains process information and learn. I also wrote The Power of Three: How to Simplify Your Life to Amplify Your Personal and Professional Success, but be warned that it's meant for adults who want to thrive and are comfortable with four letter words.

Dual Coding Blitz: A 5-Minute Strategy to Improve Student Memory

In one ear. Out the other.

In one eye. Out the other. Just try not to picture it.

Unless you use an effective dual-coding strategy.

Dual coding works because the brain processes visual and verbal information through partially separate systems—the visuospatial and the verbal. This leads to encoding of the same ideas in two different ways.

When student brains store the same content as both words and images, they build stronger neural connections that make later information retrieval easier.

This also reduces cognitive load and strengthens memory as the brain has more retrieval cues (memory triggers) to work with and more than one way of accessing the information.

So next time your students are learning, combine verbal with visual and the learning will be more than usual.

Here’s the way:

Dual coding strategy diagram showing how to implement  the dual coding blitz and the science behind why it improves learning and memory.

How to Use the Dual Coding Blitz Strategy

  1. Show a diagram, chart, or visual for about 30 seconds.

  2. Remove it from view completely.

  3. Individual students recreate it from memory with simple sketches and words.

  4. Have them compare with a partner and fill in gaps.

  5. (Optional) Show the original again for a quick self-check or round 2 if you have more than 5 minutes.

Why Dual Coding Improves Memory and Learning

Promotes Retrieval, Not Copying

Once the image is gone, students can’t rely on recognition. They have to pull it from memory, which strengthens learning.

Combines Two Modes of Learning

Students combine visuals (sketches) and verbal/textual explanations. Two ways of encoding = better memory.

Reduces Cognitive Overload

Instead of processing a complex diagram all at once, students rebuild it in pieces. Chunking information like this makes learning easier.

Reveals Gaps In Knowledge

Missing labels or incorrect parts show exactly what students don’t understand—so you can fix it immediately.

Pro Tips To Increase Student Engagement

  • Use simple, clear visuals (avoid cluttered slides).

  • Give a focus: “Pay attention to the…” or “Notice the...”

  • Emphasize accuracy over art and keep it short (the quick and dirty…).

From Seeing to Remembering

While seeing is believing, it isn’t necessarily learning.

Unless they recall and rebuild what they saw.

Then, they can keep building on top of it, but that’s next time so stay tuned.

BOOKS & TOOLS

[Earth Science] Terraforming Mars: The Red Planet "Shark Tank" Innovation Challenge
$4.00

Are your students tired of just reading about Earth? Do they gaze longingly at the night sky, dreaming of a future beyond textbook pages? Excellent! Because today, we're not just learning about science; we're making science. We're launching them into the ultimate entrepreneurial challenge: Terraforming Mars: The Red Planet "Shark Tank" Innovation Challenge!

Forget your quaint little recycling programs. We're talking about taking a dusty, desolate rock and turning it into a vacation spot for humanity.

This isn't just a project; it's a desperate plea from the future (and a cunning way to keep them engaged). Your students will become "Terraforming Tech Startups," armed with nothing but their wits, some internet access, and a burgeoning understanding of how Earth actually works. Because, let's be honest, trying to make Mars habitable without understanding our own planet's life support systems is like trying to bake a cake without knowing what flour is.

Prepare for an explosion of creativity (hopefully not literal, on Mars or in your classroom) as they grapple with the fundamental cycles that make life possible. The competitive drive to secure that "virtual investment" (and bragging rights) will channel all their boundless energy into productive, scientific output. Just try to keep the "mad scientist" cackles to a minimum.

Student Learning and Performance Objectives:

  1. Demonstrate understanding of the Carbon, Water, Nitrogen, and Oxygen cycles.

  2. Apply your knowledge of the principles of these cycles to design an ecosystem on a different planet (e.g. Mars).

  3. Illustrate how biogeochemical cycles support life in a closed system (Earth, Mars colony, dome ecosystem etc.).

  4. Pitch your solutions to practice collaboration, critical thinking, and creative problem-solving/design.

What's included:

  1. 20 slides that introduce, explain, and guide the teacher and students

  2. Introductory popcorn reading activity

  3. Research Guide (G-doc link): Includes Note-taking space and links to reputable websites for students to use.

  4. Project timeline and detailed tasks for each day

  5. Group Roles explained in detail

  6. Detailed teacher notes on prep, main lesson, and best practices

  7. List of materials

  8. Student Learning and Performance Objectives

  9. Grading Rubric and Peer Evaluation Form

 
EQUITY Poster
$1.50

Equity-Promoting Classroom Poster. What does EQUITY in the classroom look like?

  • Everyone has a different start and finish line

  • Quality is more important that quantity

  • Understanding that diversity makes us stronger

  • Inclusion despite beliefs, appearances, and circumstances

  • Thoughtfulness lowers barriers and reduces biases

  • Yesterday's mistakes are today's learning agenda

You can teach your students about equity and make it a daily classroom practice using this inspirational poster, which also includes images that accompany the equity description. You can discuss each letter characteristic with your students as a way of introducing your inclusive classroom and display it prominently as a reminder that diversity makes the classroom community stronger.

 
Climate Change Debate: The Earth Science Intellectual Thunderdome
$4.00

In this 3- to 4-day lesson, designed for a high school Earth and Space Science classroom, student groups are assigned and investigate 4 leading solutions to the climate change crisis our planet is experiencing. Then, they are called upon to debate against each other to try to convince others that their solution is the most viable and provide counterarguments against other solutions. It’s an intellectual thunderdome in which students are encouraged to use science to attacks each others points of view on climate change but not character.

Why and how does this learning strategy work?

Rote memorization out; seeking answers and deeper learning in.

The debate-style approach to learning is engaging and motivating for learners, because they are challenged to use real evidence and their wits to outmaneuver their opposition.

Not only do they act as investigators, developing communication, collaboration, and argumentation skills but they learn about viable solutions to the climate change conundrum we all find ourselves in. They learn Earth and Space Science content while investigating and debating solutions to a real-world phenomenon, which is what the Next Generation Science Standards (NGSS) call for.

Student Learning and Performance Objectives:

  1. Research multiple, complex climate change solutions to discover that the world is more complicated than a single TikTok trend.

  2. Articulate scientific arguments with actual evidence.

  3. Listen to opposing viewpoints, to hone "social awareness" skills.

  4. Realize that climate change solutions are multi-faceted, messy, and require more than just good vibes.

  5. Describe and support with, not mere belief but actual evidence, the leading climate solutions proposed by, not the coven of online witches but the scientific community.

What's included:

  1. 24 slides that introduce, explain, and guide the teacher and students

  2. Detailed teacher notes on prep, main lesson, and follow up activities

  3. General Lesson flow for teacher to follow to make it all seamless

  4. A short and funny “hook” to increase student buy in

  5. Detailed student directions

  6. A list (research starter pack) of links to legit, scientific websites for students to use.

  7. Group roles (team jobs) with descriptions of what each entails.

  8. 4 climate change solutions to assign to 4 different student groups

  9. Student Learning and Performance Objectives

  10. Detailed Grading Rubric to guide students and make assessment easy

  11. Debate Day introduction and format description

  12. Follow up discussion questions (reflection and debrief)
