The Design of Learning Media to Reduce Cognitive Load Using the Split-Attention Principle
Main Article Content
Abstract
The design of learning media aims for learners to study content in order to create their own knowledge. During the learning process, learners experience cognitive load depending on the difficulty of content and the design of learning media. When learning materials comprise diverse formats, such as text, images, audio, or video, inappropriate or inconsistent content placement may lead to a phenomenon known as the split-attention effect. This phenomenon occurs when learners need to allocate cognitive resources to gather and link information from separate sources, resulting in unnecessary cognitive load. And if cognitive load exceeds learners' limits or cognitive overload occurs, it will affect learning efficiency. Therefore, this article explains the principles of human information processing and memory limitations that cause cognitive load. It then presents media design that reduces cognitive load using the principle of reducing split attention, examples of learning media design using the principle of reducing split attention, and the impact of the principle of reducing split attention on learning media design as a guideline for future learning media design.
