If you reach for a pen to draw arrows before you have finished reading the question, someone has probably called you a visual learner and handed you a list of tips that mostly say "use color" and "watch videos." This page gives you five concrete ways to turn what you study into pictures, and a simple test that shows which of them actually help you remember.

What the label can and cannot tell you

The idea behind it is that each person has a learning style, and that material presented in that style is learned better. Pashler, McDaniel, Rohrer and Bjork went looking for the evidence in 2008, and the visual learner was their own worked example. People readily say how they like information presented, they found, but experiments able to test the matching claim were rare, and several of the sound ones contradicted it.

A later study came at the question from the visual side. Knoll and colleagues scored people on a questionnaire about preferring words or pictures, then had them study word pairs and picture pairs. Those who leaned toward pictures felt more confident about the pictures, but their scores had no link to what they actually recalled. The preference shaped how learning felt, not how much of it stuck.

None of that makes your preference worthless. A method you enjoy is a method you will open again tomorrow. It only means the reason to draw is not that you belong to a type. Drawing helps, when it helps, for reasons that apply to nearly everyone, and the only way to learn which kind of drawing helps you is to try each one on your own material and check.

Five ways to picture what you study

• Concept map. Put the big idea in a circle in the middle, branch out to its parts, and write on each line how the two ideas connect. It suits causes, effects and ideas that link up.
• Timeline. One long line, the events in order, a tiny picture above each one. It suits history, plots and anything with steps.
• Diagram. Draw the thing itself, from a cell to a volcano, and label every part with what it does. It suits structures and systems.
• Sketchnotes. Notes made of small drawings joined by arrows, one idea per doodle and only a few words each. They suit lectures, videos and long chapters.
• Dual coding. A simple picture beside each definition or step, then the picture explained in your own words. It suits vocabulary and abstract ideas.

Why the redraw matters more than the first drawing

Building a tidy concept map with the textbook open feels productive, and it does less than it feels like. In Karpicke and Blunt's experiments, students who practiced recalling a science text learned more than students who built concept maps while studying it, and the gap held even when the final test asked everyone to draw a concept map. Pulling the material back out of memory did the heavy work.

Drawing earns its place as well. In the run of experiments summarized by Fernandes, Wammes and Meade, people remembered words, pictures and even textbook definitions better after drawing them, and drawing beat writing the material out, imagining it, and tracing a ready-made picture. So make the drawing with your own hand rather than copying the figure in the book, and then make it again later from memory. That second drawing is the test, and it counts as studying at the same time.

How the sketchbook works

The page opens on five pencil sketches, one for each technique. Tap one and its page opens with a single instruction, the kind of material it suits, and a line for the subject in front of you. Study that way on paper. Later that day or the next morning, cover your notes, redraw it on a blank page, compare the two, and tap how much came back, from very little to nearly all.

Every logged redraw inks its sketch in by how much you recalled, so the techniques that work for you darken while the rest stay in pencil. Each page holds four redraws. Once a technique has two, the reading ranks it against the others, and it warns you when a lead rests on a single subject, because a timeline of the Civil War and a timeline of cell division are not equally hard to recall. It also refuses a second redraw of the same subject on the same day, since a retry an hour later mostly measures what is still fresh.

When to use it

Open it when you sit down with something you need to remember for a test, and give each technique two honest tries before you decide anything about it. For a wider look at your habits, the Study Style Quiz scores spacing, self-testing and focus. If you think better on your feet, the Hands-On Study Pegboard pairs movement with the same kind of recall. And when you want recall with no drawing at all, the Blurting Pad gives you a silent timer and a blank page.

Draw it once to learn it, and again to find out what stayed.
