Audio-Visual Picture Mnemonics and Spaced Repetition Can Improve Student Learning
AUDIO-VISUAL PICTURE MNEMONICS AND SPACED REPETITION CAN IMPROVE STUDENT LEARNING
Introduction
Attrition in higher education has been a focus of educators for decades. For professional programs, the problem is particularly acute. The dropout rate has been increasing for medical students in recent years, from 5 to 20%1, and can be as high as 45%2 of nursing students at some institutions. High attrition can impact an institution s reputation and staff and student morale, and is being actively addressed by learning specialists and academic success departments at many professional healthcare schools.
Since the root causes of attrition can be varied and complex3, educators turn to a broad range of solutions. Online learning resources have grown in popularity as learning intervention tools used by academic success coordinators, and by classroom faculty to engage millennial students and keep them coming to class prepared and ready to learn.
The rise in popularity of picture mnemonics and AI-algorithm-driven software has led to the development of study resources that help higher education students learn and educators to engage them. This white paper addresses the science underlying the effectiveness of using picture mnemonics for learning in higher education, along with a research study to demonstrate the effectiveness of this approach for healthcare students.
The stakes are higher than ever. The competition for post-graduate placement has risen dramatically, putting pressure on institutions to increase resources and support for students in order to maintain exit statistics. With medical student application growth outpacing the growth of schools and residency programs, institutions provide resources and intervention support to prepare their students to achieve highest possible exam scores, ensuring that their students will get matched to a limited number of residency program spots. A similar situation exists for nursing programs over 50% of MSN programs turned away qualified applicants since 2014.

What are Picture Mnemonics?
The a a g, A c e h a h a d d , ba ed c e ce. Simply put, a complex idea can be expressed better with a single image than a block of text, and a fact associated with a wacky image will be remembered longer, too. The e b ca he trigger memories of facts and hard-to-remember information, improving learning and performance.
The Science of Memory Since early Roman times, people have been fascinated by the science of memory, developing techniques to improve memory function (encoding), enhance retrieval and reduce forgetting. The Greek orators actively used the Method of Loci, using mnemonics to memorize a list. In recent centuries, philosophers, biologists, and psychologists have researched and documented memory phenomenon such as Picture Superiority effect, Dual-coding theory and Von Restorff effect. Hermann Ebbinghaus charted the rate at which information is forgotten over time (known as the forgetting curve), which led to the discovery of he ac g effec 4.
All of this research has led to the development of techniques that improve one s ability to learn and retain knowledge. In turn, better knowledge retention can lead to improved conceptual understanding and increase the likelihood that what is learned can be effectively applied to solving real-life problems and scenarios.

How Memories are Formed
Memory formation is a three-part process. Memories are encoded, stored, and then retrieved.
Step 1: Encoding It all starts with the senses, where external stimuli (visual, acoustic, tactile and semantic) are converted into electrical signals that are sent to the brain for processing. Based on how information is presented has a major impact on where and how well it is encoded in the brain. A few memory phenomena come into play that can be leveraged to encode more durable memories.
Dual Coding Theory Verbal and nonverbal information is processed through different channels in our brain, and provide separate representations for information. For example, seeing a picture of a circle ce ed a d ffe e e a a h a ha hea g he d c c e. T f a g memory Dual Coding Theory says that both channels should be used concurrently when e c d g f a ( a a c c e a d hea he d c c e a he a e e)5.
Picture Superiority Effect Picture superiority effect basically states that images are remembered better than text alone. Therefore visual cues can facilitate recall of facts and information6.
Von Restorff Effect The isolation effect explains that weird, odd or unique things tend to stand out and are e e be ed be e . The e e h g a d , e e f familiar or nonsensical, the easier it will be to remember it7.
Humor Effect When emotions run high experiences are more likely to be remembered. Facts are remembered better when they are funny, rather than mundane, because laughter evokes emotion that improves memory8.

Step 2 Once new information is encoded, storage is the next step in the memory formation process. Picture mnemonics are tools to help encode, store and recall information more easily.
A very basic form of a mnemonic, and usually the most common, is an acronym which takes the first letter of every word in a list and creates a new word. A few examples are ROYGBIV for the colors of the rainbow or FACE and EGBDF for notes on the treble clef in music.
However, with some acronyms, it s hard to remember what each letter stands for. Using the Baker-Baker Paradox, a phonetic representation and a visual character can be developed to accompany the acronym, because the more associations that are attached to something, the higher likelihood a fact will be remembered and recalled.
Adding an interaction with another visual character forms more associations that lead to stronger memories. Th a a he g e h d10.

Step 3 Retrieval is the final step that will ensure one can always recall memories when we need them, even in a stressful situation such as taking an exam.
A huge misconception is that rereading a textbook, reviewing study guides and notes over and over will get information to stick. Just memorizing the visual text creates an illusion of mastery; repetition is an ineffective tool in mastering a complex subject at an advanced level, information is only being re-encoded over and over again, not learned for the long term11.

Material that cannot easily be recalled must be studied again. But there is a core learning strategy for long term retention that is scientifically proven to lead to more effective retention: Spaced Repetition.

Spaced repetition involves reviewing information spaced out over increasing intervals of time. With each review, the slope of the curve becomes less and less, until it s eventually stored as a long-term memory.
The most efficient approach is to review information right before it is forgotten. Unfortunately, that is nearly impossible for a student to predict. Recently software-based study tools have been developed to incorporate automated spaced repetition algorithms so that student reviews are personalized to their performance with active recall quizzes13.

Validation for Picture Mnemonics
Medical students Ron Robertson and Adeel Yang leveraged the scientific research behind image mnemonics and created a tool for medical, nursing and other students in the healthcare professions to memorize hard-to-remember facts required to pass class and board exams and excel in school. They took thousands of topics and created wacky characters tied together with humorous stories and audio and put it online to create the ultimate interactive studying system for retention and recall.
In a single-center, randomized, subject-blinded, controlled study14 the Picmonic Learning System was compared to text-based material and found that students using Picmonic picture mnemonics improved student retention of facts by 331% over a one month period, using a paired matching method of recall. Using free recall, students showed 200% improvement.
With either method of retrieval, students using Picmonic s picture mnemonics outperformed the control group.

Another way of looking at the data is by observing how much Picmonic lessened the forgetting curve. Using paired matching method of recall, even if students in the control and test group had recalled the same number of facts during session 1, students who used Picmonic remembered greater than double the number of facts than the control group at the end of the 1 month period.
Using free recall, students who used Picmonic recalled nearly double the number of facts than the control group.

Ho Picmonic Picture Mnemonics Work
To create a Picmonic, a concept/topic of interest is selected and the most important attributes are identified and encoded into memorable characters. Characters are created using a phonetic keyword mnemonic strategy, following the process of encoding information described by Levin and Levin in their 1990 study. Converting a word into its sound-alike, picturable equivalent creates a memory anchor that enables recall.

Each Picmonic includes a 10 question multiple choice quiz that is delivered to the student right after the Picmonic characters and story are viewed. By including built-in quizzes for each Picmonic, students are given an opportunity to practice low stakes recall, a technique which has been proven to improve retention16.
Because personalization can create a more engaging experience that leads to greater learning effectiveness, Picmonic incorporates learning algorithms that adapt to a students learning patterns, ensuring efficient and effective knowledge mastery and retention.
