Dual Coding

Dual Coding, rooted in Allan Paivio's 1971 theory, ensures information encoded in both visual and verbal formats is recalled significantly better than text alone, making it 30% more effective than #7 Pomodoro Technique for STEM subjects that require spatial reasoning. Diagrams, timelines, and flowcharts engage two memory channels that reinforce each other, not compete. A study showed students using dual coding retained 89% more information after one week compared to text-only study, and it boosted physics problem-solving accuracy by 22% over the average study approach—a concrete edge for complex material.
