Key Findings

  • 01A dedicated instrument is needed to measure extraneous cognitive load stemming from mobile learning UI design, as general cognitive load measures may not be specific enough.
  • 02Adjustments to the measurement scale (e.g., expanding from 4-point to 10-point) and task reduction can improve reliability.
  • 03Extraneous cognitive load is directly influenced by UI design complexity, not the learning content itself.
02

Application

Design takeaway

When designing mobile learning applications, actively measure and reduce extraneous cognitive load by simplifying the user interface.

How to apply

Use a validated questionnaire to assess the extraneous cognitive load induced by your mobile learning application's interface during user testing.

Project actions

  • 01When designing an interface, consider how each element might add to a user's mental effort.
  • 02Think about how to test if your design is confusing users, not just if they can use it.
03

Method & Evidence

AimTo develop and evaluate a subjective instrument for measuring extraneous cognitive load specifically caused by user interface design in mobile learning applications.
MethodInstrument development and validation
ProcedureThe study involved pretesting a questionnaire with a small group to establish its foundation, followed by pilot experiments to validate the instrument and refine experimental procedures. The NASA-TLX was used to analyze the relationship between overall cognitive load and extraneous load related to UI criteria.
ContextMobile learning applications

Variables

IVUser interface design elements (e.g., complexity, layout, navigation)
DVExtraneous cognitive load
CVLearning content, device type, user's prior knowledge
04

Strengths & Limitations

Strengths

  • +Development of a novel instrument for a specific context.
  • +Validation through experimental procedures.

Limitations

It can be challenging to isolate the impact of UI design from the content itself when measuring cognitive load.

Reliability & validity

The study aimed to establish reliability through scale adjustments and pilot testing, and validity by correlating extraneous load with overall cognitive load and UI criteria.

Think critically

How might the cultural context or prior digital literacy of users influence their extraneous cognitive load when interacting with a mobile learning interface?

05

Design Principles

"Minimize extraneous cognitive load by designing intuitive and uncluttered user interfaces for mobile learning experiences."

Poorly designed user interfaces in mobile learning applications can inadvertently increase cognitive load, diverting attention from learning content. Developing tools to specifically measure this extraneous load allows designers to identify and rectify UI elements that cause unnecessary mental effort, thereby enhancing the overall learning experience and effectiveness.

06

What This Means for Your Design

This research created a way to ask users how much a mobile learning app's buttons and menus confuse them, so designers can make apps that are easier to learn from.

How to use in your project

  • 1.Use the concept of extraneous cognitive load to justify design choices aimed at simplifying interfaces.
  • 2.Refer to this research when discussing the importance of user interface design in educational technology.

Quick Cite

Paragraph starter

This research highlights the critical role of user interface design in mobile learning, demonstrating that extraneous cognitive load, a measure of mental effort imposed by the interface rather than the content, can significantly hinder learning. The development of a specific instrument to quantify this load provides a valuable tool for designers to identify and mitigate UI-induced distractions, ultimately leading to more effective and user-friendly educational applications.
