Avoid cognitive overload and enhance learning
The melody of music associated with e-learning courses often sparks captivating discussion among teachers and instructional designers. While conventional wisdom may praise music’s ability to enhance engagement and enrich learning, emerging insights from the field of cognitive science point to a more complex outcome. In particular, theories of cognitive load and coherence in instructional design suggest that music, when not harmoniously integrated, can disharmoniously influence learners. The discussion in this article unfolds within the nuances of cognitive load theory and the realism of designing e-learning experiences, especially within the specialized scope of systems training.
The puzzle of cognitive load
The focus of our discussion is Cognitive load theory, which focuses on the limited capacity of our working memory. This space, albeit limited, in our minds is where we temporarily store and process information. The essence of creating effective e-learning experiences is to improve alignment with our working memory capabilities. When training inadvertently contributes to cognitive overload—through complex tasks, unstructured content, or the unnecessary addition of background music—it risks overwhelming the learner. This overload hinders the smooth transfer of information to long-term memory, which is the repository for future retrieval and application. This means that cognitive overload occurs when working memory becomes overwhelmed with too much e-learning or complex information. This can impair the learning process and prevent the transfer of knowledge into long-term memory.
Music affects cognitive load and learning
The inclusion of music in e-learning materials appears as a quintessential example of a strange element. While individual reactions to music can vary greatly depending on personal preferences, overall mood, and the nature of the task, the general trend indicates an increase in cognitive load. This additional auditory information competes with the core course content, impairing the learner’s attention and reducing the ability to process important information. This means that attempts to ‘excite’ or enhance engagement through music may actually reduce the effectiveness of the course.
In practical terms, this means that music can contain both Positive and negative effects In e-learning, depending on the genre, purpose and context of the music. Music can enhance mood, motivation, and engagement, which are important for learning. However, music can also increase cognitive load by competing with the auditory channel for working memory, especially if the music contains lyrics, is unfamiliar, or is unrelated to the learning content. This can distract the learner and reduce the attention and resources available to process essential information.
The specific symphony of system training
The complexities of systems training – where learners are equipped with the knowledge and skills needed to navigate software or hardware – exemplify the complex relationship between music and learning. These training programs require the learner to integrate verbal and visual information. Background music introduces an unwanted layer, complicating the cognitive process by adding irrelevant information that learners must sift through, thus muddying the educational waters.
Crafting e-learning symphonies
To alleviate cognitive overload, instructional designers are tasked with curating e-learning experiences that resonate with learners without overwhelming them. Following the principle of coherence, which calls for the exclusion of unnecessary elements, can lead to more consistent educational outcomes. Design strategies may include thoughtful inclusion or exclusion of background music, ensuring that it supports rather than detracts from educational objectives. This approach acknowledges the situational effectiveness of music, and carefully regulates its presence to complement the learning process rather than compete with it.
Emerging where music finds its place
Despite its potential risks, music finds its place in certain e-learning contexts. In scenarios such as soft skills training, music can amplify storytelling, enhancing engagement and emotional connection with the content. In systems training, strategic system sound stimuli (e.g., clicks when a button is pressed) may be more useful than music, as they provide cues that reinforce learning without unnecessary distraction. If necessary, instrumental or non-singing music may serve as a favorable background for tasks that require less cognitive effort, such as improving the study environment by regulating mood or suppressing background noise.
The key to using music effectively in e-learning courses is to align the music with the learning objectives and characteristics of the learners. Music should be used sparingly, selectively, and strategically to avoid cognitive overload and enhance learning. Some best practices for using music in eLearning courses are:
- Use music only when it supports learning objectives, such as creating context, setting tone, or reinforcing a message.
- Use music only at the beginning, end, or transitions of the course to avoid distracting the learner during core content.
- Consider music with your opening eLearning screen or accompanying an opening video.
- Give the learner the option to turn off or adjust the music to suit different preferences and needs.
- If necessary for study stimulation, use low-volume, consistent music with an ideal beats per minute to avoid interfering with cycle information.
Conclusion: Silence that says a lot
As we navigate music and eLearning, it is clear that a rigorous, research-based approach is critical. Music, with all its vitality and potential for enrichment, must be integrated wisely to avoid cognitive discord in the educational symphony. By supporting considerations of cognitive load and coherence in design, instructional designers can author e-learning experiences that resonate deeply without the cacophony of unwarranted distractions. In the fine art of eLearning design, silence can, sometimes, be the most eloquent teacher, allowing the essence of the content to flourish.
