We had a look at the research to see how Cognitive Load Theory can improve teaching, so that it will in turn improve student learning. In this blog, we look at four practical classroom strategies based on a subset of the theory, known as The Redundancy Effect.

Feb 21, 2025 · In short, redundancy occurs when the same info is presented via both channels simultaneously. It’s redundancy if the simultaneous listening and viewing confers no additional benefit than doing either one alone.

The redundancy effect refers to the phenomenon in instruction where learning is hindered when additional information is presented to learners compared to the presentation of less information. It can take one of two forms.

Feb 12, 2023 · The results show that content redundancy increases learning outcomes and decreases cognitive load, while modal redundancy decreases learning outcomes and increases cognitive load. On the theoretical level, these findings confirm the usefulness to distinguish content redundancy from modal redundancy.

This paper reviews empirical research on the redundancy effect (63 studies) and classifies two types of redundancy: (1) content redundancy, and (2) working memory channel redundancy.

Aug 9, 2024 · The redundancy effect refers to the negative impact when two or more sources provide redundant information simultaneously, potentially overloading the cognitive capacity of working memory . However, empirical evidence demonstrates a diverse range of redundancy effects , from enhancements in learning to drawbacks or no effects . This variability ...

Redundant information is information that is unnecessary. The redundancy effect occurs when information presented with redundant information removed results in greater learning than when redundant information is included.

While most studies confirm that redundancy is harmful to learning, there are two theoretical approaches to redundancy. The first understands redundancy as a contentual overlap that puts demand on the limited cognitive capacities of the learner.

Aug 5, 2014 · The redundancy principle (or redundancy effect) suggests that redundant material interferes with rather than facilitates learning. Redundancy occurs when the same information is presented concurrently in multiple forms or is unnecessarily elaborated.

multiple sources of information. The redundancy effect may occur when the multiple sources of information can be understood separately without. the need for mental integration. Written or spoken text that simply re-describes a diagram that can be fully understood with.
