Using a free business proposal template, this blog aims to explain how audio visual diagrams can enhance memory retention when learning new concepts or topics. It will discuss the cognitive science behind why audio visual aids are effective for learning and discuss specific examples of how diagrams, graphs, illustrations and other visual elements paired with audio helps cement new information in our long term memory.
The Science Behind Memory Retention
The human brain processes and retains information in different ways based on the sensory modality used. Visual information is remembered better than just listening or reading alone. When we see and hear information simultaneously through audio visual tools, it engages both the visual and auditory areas of the brain. This dual coding helps trap the new learning in two memory stores rather than one, making it harder to forget. Cognitive scientists have shown our working memory can only hold a limited amount if just listening or reading text. Visual representations free up space in our working memory to integrate more complex ideas. Pictures also spark emotional arousal which stimulates the amygdala and improves consolidation of memories from short term to long term storage areas in the brain.
Effects of Diagrams and Illustrations
One form of visual representation that enhances memory is the use of diagrams, graphs, charts, illustrations and other non-text based explanations of concepts. Research has demonstrated visual diagrams are 23% more memorable than text alone. They allow abstract ideas and relationships to be presented in a concrete, spatial format our brains can easily grasp. Labelling diagrams with an audio explanation strengthens the connections between the visual representation and its meaning. It gives the brain redundant coding pathways to latch on to for better recall later. Concept maps, process flows, anatomical diagrams, mathematical graphs are all examples of visual concepts that pair well with an instructor's voiceover to maximize comprehension and memory of challenging topics.
Uses of Interactive Tools
With advances in technology, audio visual learning tools have become highly interactive. Platforms which gamify the learning process and give students control over their learning path through games, quizzes, and simulations have shown strong memory results. Being an active learner rather than passive observer engages higher order thinking skills and motivation centers of the brain. One study found 90% retention rates for students who interacted with online flashcard software versus just reading cards. Having the ability to pause, rewind, and review audio visual material is also beneficial for concentrating attention on difficult areas until they are understood. Educators are now able to easily create their own interactive content or curate pre-existing explainer videos, virtual labs, and digital graphic organizers tailored to their curriculum.
Applying Visual Mnemonics
Mnemonic devices like acronyms, rhymes, illustrations, and storytelling have been demonstrated to boost long term memorization significantly. By pairing a visual image with an idea, students have a vivid mental hook to recall the concept later on exam day. One method is using a simple drawing with labels to associate complex terms or processes. For example, drawing the life cycle of a frog could represent the learning stages in Bloom's taxonomy. Iconic photographs work too, such as attaching famous paintings to historical events or dates. Storytelling is another mnemonic approach effective for remembering sequencing information through visually recalling plot points of a narrative. Teachers should experiment incorporating creative visual mnemonics tailored to difficult topics in their lessons.
Implementing in the Classroom
There are many practical ways for educators to integrate audio visual diagrams into their classroom instruction. Free or low cost tools like PowerPoint, Canva, Jamboard, Prezi allow creation of customized presentations with embedded diagrams, photos, and instructor narration. Videos from Khan Academy, TedEd, Crash Course, and other open educational resources complement difficult textbook topics well. Flipping the classroom lets students watch explainer videos as homework to free up class time for hands on practice with the concepts using visual representations. Teachers can have students work individually or collaboratively in groups to design, label, and present their own diagrams for peer learning. Assessments should incorporate visual questions like filling in diagrams or sorting/matching charts to evaluate retention of key ideas. With creative implementation, audio visuals have enormous potential to boost every student's understanding and long term memory of subject matter.
Conclusion
In summary, cognitive science has proven audio visual aids are highly effective for augmenting memory retention due to their ability to engage both auditory and visual processing centers of the brain simultaneously. Paired with the inherent memorability of diagrams, illustrations, interactive tools, and visual mnemonic devices, these multi-sensory learning methods give students redundant pathways to consolidate new knowledge into long term memory stores. Educators should feel empowered to freely utilize the endless possibilities of audio visual material available both in person and online to radically enhance learning outcomes for every student, especially those who struggle with lecture-heavy environments. By making visual representations and instructor narration a core component of lesson plans across subjects, schools can unleash student potential like never before.
