A student ruffles through his notes, textbook, and lectures for several hours trying to cram every last bit of information before the upcoming pharmacology exam. He arrives on test day, reads the first question, and his heart sinks; he knows he read about it, but just can’t remember the answer. Memory is an important part of teaching/learning and involves more than just recollection. Memory involves the learning, understanding, and the ability to link information together whether it was taught or experienced/researched on one’s own. When a teacher evaluates a student’s memory through tests, they are assessing more than just recall, but rather a deeper understanding of the information.
Students today live in an age of technology where information is always available at their fingertips and many students come to believe that recalling information really isn’t as important as it used to be. For example, how many of us can recall a friend’s phone number any more? Moreover, we are more likely to remember things we find interesting, which can pose a challenge in some classes. Students are more likely to achieve higher marks in courses related to their major or in electives, and more likely to struggle in general education classes.1
The responsibility for remembering and retaining information is mutual — both the student and the teacher need to do their part. Educators need to pay attention to the “learning” aspect of “teaching/learning” and help students develop strategies to retain and understand the information. When a student is presented with new information, it is first held in short-term (aka working) memory while it is processed. Short-term memory is limited in capacity and duration — only five to nine items can be held in short-term memory for about ten to twenty seconds.2
This is where memory aids can come in handy. Several strategies have proven effective to facilitate memorization and long-term retention including mnemonics and spatial visualization.
- Mnemonics are strategies for associating words or phrases with a list of facts or principles.
- Spatial visualization involves assigning pieces of information with everyday actions and objects. Then when it is time to recall the information, imagining those actions and objects associated with the information.
Many of us first learned about mnemonics in childhood. For example, “Every Good Boy Does Fine” was a useful way to remember the major musical notes and “Please Excuse My Dear Aunt Sally” was a mnemonic I learned to remember the order of operations in middle school math class. Other methods used in our early schooling included rhymes to remember what year “Columbus sailed the ocean blue” and the months that have 30 days. While mnemonics were useful for retaining these “elementary school” concepts, can these principles be applied to college-level courses where the content is much more detailed and sophisticated? In short, yes! One study tested the use of mnemonics in college students who were required to match a portrait to the name of its artist. Students who used mnemonics to recall the information significantly outperformed those who did not.3 The technique has been used to teach engineering students. Eighty percent of the students reporting they benefited from the use of mnemonics and believe it help improved their exam scores.3
Mnemonics are rarely used in pharmacy school and vast amounts of information are presented to students from PowerPoint slides. From my experience, cramming for tests is common and most student use the repeating method, reading and re-reading handouts and notes as many times as possible shortly before an exam. This works well for some types of information and for a short period of time (long enough to remember it for the exam), but it is soon forgotten. A few instructors (but not many) still include memory aids in their presentations. I still remember “Please Let Grandma Brown Bring Peaches To Your Wedding” as a way of remembering the colors of warfarin tablets (pink/ lavender/ green/ brown/ blue/ peach/ teal/ yellow/ white). However, mnemonics are used far less often in college than in elementary school.
Another memory aid that health professional students could use is SketchyPharm and SketchyMedical.com which uses spatial visualization to help learners understand complex topics. This is a subscription-based service first developed for medical students but has one section specifically related to pharmacy topics. A picture is presented and each item in the picture is associated with a more complex piece of information, and essentially helps the student visualize what they are learning through storytelling. This gives the phrase “a picture is worth a thousand words” a whole new meaning.4 While there are no peer reviewed research articles (yet) to support its effectiveness, medical students from the University of North Carolina rated the use SketchyPharm higher than many other common exam prep techniques (like flash cards) and 83% of students claimed they used it to study for their Step 1 medical licensure exam.5
The use of memory aids diminishes as a student progress from elementary school, to high school, to college, and beyond. Why? Memory aids work and instructors should be using mnemonics and encouraging students to use spatial visualization to not only recall information but move important facts out of short-term memory. There are lots of websites to help create mnemonics; so, there no excuse not to incorporate them into lectures in combination with active learning activities. Encouraging students to use SketchyPharm or spatial visualization strategies during and after a lecture can really solidify the information being taught.
