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

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.
