# Free Online CPD Course for International Schools: Dual Coding (With Certificate)

By Flavia Belham · Published 2026-02-16 · Updated 2026-03-02

How can we present information so that students understand it more clearly and remember it longer?

Dual coding is one of the most powerful, research-informed strategies available to teachers today. When used effectively, it improves clarity, reduces cognitive overload and strengthens long-term retention.

That’s why we’re excited to offer a free online CPD course: Dual Coding (written by Oliver Caviglioli)

## Why Dual Coding Matters in International Schools

In international school settings, teachers often work with:

- Students from diverse cultural backgrounds
- Students with varying prior knowledge
- Multilingual learners
- High academic expectations and inspection standards
- Content-heavy curricula (IGCSE, IB, British curriculum and equivalents)

Presenting information clearly is critical.

Dual coding — combining words and visuals effectively — helps:

- Reduce cognitive overload
- Improve comprehension
- Strengthen memory retention
- Support EAL / ESL learners
- Clarify complex concepts

When implemented well, dual coding transforms how students process and retain information.
