7 Evidence-Based Study Strategies (& How to Use Each) — Transcript
Full transcript
- 0:00As doctors, we treat patients with
- 0:02evidence-based medicine, meaning
- 0:04treatment modalities that are backed
- 0:05with sound scientific research. We can
- 0:08do the same when it comes to study
- 0:09strategies. These are the seven
- 0:11evidence-based study techniques with
- 0:13supporting scientific evidence. Doctor
- 0:16Jabbal, medschoolinsiders.com.
- 0:18We can thank the psychologist Hermann
- 0:20Ebbinghaus for studying his own memory
- 0:22and generating what is known as the
- 0:24forgetting curve. In its simplest terms,
- 0:26the forgetting curve demonstrates that
- 0:28after forming a memory, we gradually
- 0:30forget more and more of it as time
- 0:32elapses. With attempts to retain the
- 0:34information at increasing intervals just
- 0:36before we forget it, the memory becomes
- 0:38more durable. We know from neuroscience
- 0:40fundamentals that repetition potentiates
- 0:43neural connections and allows us to
- 0:45remember information more effectively.
- 0:47The problem is that we have far too much
- 0:49information to learn. We can't repeat
- 0:51every fact we need to know on a daily
- 0:53basis. Enter the spacing effect. By
- 0:56repeated exposures to a piece of
- 0:58information at increasing intervals
- 1:00between each repetition, we can optimize
- 1:02memorization and retain the most
- 1:04information in the least amount of time.
- 1:06Spaced repetition is most powerful when
- 1:08the timing is just right. If too little
- 1:10time elapses between repetitions, the
- 1:13information is not reinforced as
- 1:14strongly. If too much time passes, you
- 1:17forget and are unable to recall the
- 1:19desired information. If we see the same
- 1:21information multiple times over
- 1:23increasing intervals, we'll be far more
- 1:25effective at encoding those facts into
- 1:27long-term memory. This is why cramming
- 1:29is so ineffective. Studying for 8 hours
- 1:32over 2 weeks will generally result in
- 1:35superior performance compared to
- 1:37studying for 8 hours in one sitting. I'm
- 1:40a big proponent of using tools and
- 1:42systems to streamline and automate
- 1:44processes. I recommend you take the same
- 1:46approach with spaced repetition. You
- 1:48could create a study schedule for
- 1:49yourself where you plan out when to
- 1:51review older lectures in addition to
- 1:53recent lectures, or alternatively, you
- 1:55can offload the process to other apps
- 1:58like Anki, which will test you on
- 1:59bite-sized pieces of information through
- 2:01flash cards and automatically schedule
- 2:03the cards based on the difficulty of
- 2:05recall for each. The most common mistake
- 2:08is procrastinating and cramming just
- 2:10days before the exam. This undermines
- 2:12any of the potential advantages of
- 2:14spaced repetition. When practicing
- 2:16spaced repetition, make sure you're
- 2:17using effective study strategies and not
- 2:19simply rereading your notes. Rereading
- 2:22your notes is a form of recognition,
- 2:24whereby you look at some facts and tell
- 2:26yourself, "Oh, yeah, I know that." This
- 2:28is unreliable. Instead, spaced
- 2:30repetition is most effective when
- 2:32combined with active recall, whereby you
- 2:34test yourself for the answer, which
- 2:36brings us to the second evidence-based
- 2:38study strategy. Active recall is the
- 2:40practice of using the testing effect to
- 2:42your advantage. If you're already using
- 2:44active recall, chances are you love it
- 2:46because of the resulting drastic
- 2:48improvement in performance. If you
- 2:50aren't using it yet, there's a bit of a
- 2:52learning curve, which may be
- 2:53discouraging. You should expect active
- 2:55recall to be a difficult process, as
- 2:57active learning methods are, by
- 2:59definition, far more challenging than
- 3:01passive forms. When it comes to active
- 3:03recall, I normally advise students to
- 3:05create flash cards through Anki or to
- 3:07use practice problems, which also has
- 3:09the added benefit of practicing
- 3:11higher-order level thinking. There are
- 3:13other ways to incorporate active recall,
- 3:14though. For example, you could write or
- 3:16sketch out everything you know about a
- 3:18certain topic without looking at your
- 3:20notes. Be as thorough as you can be, and
- 3:23afterward, check what you've written
- 3:24compared to your class notes for
- 3:26accuracy and to fill in points you may
- 3:28have missed. Many students try active
- 3:30recall for a short period of time only
- 3:32to give up soon after because they find
- 3:34it difficult. The key is to understand
- 3:36that if it feels difficult, that means
- 3:38it's working. And with anything in life,
- 3:40with practice, you'll get better at it.
- 3:42It becomes easier with time. Another
- 3:44common mistake is studying facts in
- 3:46isolation. Particularly with flash
- 3:48cards, students may focus too much on
- 3:50individual facts without adequate
- 3:52comprehension. Do not neglect
- 3:54comprehension, which means truly
- 3:55understanding the relation between ideas
- 3:57and how certain concepts are similar or
- 4:00different. Lastly, remember to not only
- 4:02practice the recall part, but also check
- 4:04your answers. If you are practicing
- 4:06recall without verifying accuracy, you
- 4:08may be reinforcing incorrect
- 4:10information. Closely intertwined with
- 4:12active recall is the concept of
- 4:14desirable difficulties. This states that
- 4:16a learning task that requires a
- 4:18considerable amount of effort will
- 4:19improve long-term performance, even
- 4:21though it may slow down learning
- 4:23initially. Research demonstrates that
- 4:25the traditional easy forms of passive
- 4:27learning show better temporary
- 4:28performance effects, but more difficult
- 4:30tasks, such as learning with active
- 4:32recall, result in improved performance
- 4:35in the long term. Think of it like going
- 4:37to the gym. If you bench press 10-lb
- 4:39dumbbells, you're technically doing
- 4:41chest exercises, but you're not
- 4:43challenging yourself enough to improve.
- 4:45This is like passive learning. On the
- 4:47other hand, if you bench press 100-lb
- 4:49dumbbells in each hand, you'd be
- 4:51exerting yourself to a far greater
- 4:52capacity, resulting in muscle breakdown
- 4:54and ultimately hypertrophy. This is a
- 4:57desirable difficulty which you are more
- 4:59readily able to achieve with tools such
- 5:01as active recall. Desirable difficulties
- 5:04is an overarching principle that serves
- 5:06as a common thread throughout the six
- 5:08other evidence-based learning
- 5:09techniques. Elaboration refers to
- 5:11further describing and explaining
- 5:13various ideas or concepts that you are
- 5:15studying to solidify your understanding
- 5:17of the material. The concept of
- 5:19elaboration sounds great, but the tricky
- 5:21part is how to effectively implement the
- 5:23technique. Here are a few suggestions.
- 5:25First, generate questions for yourself
- 5:27about how various concepts or principles
- 5:29work and the underlying reasons as to
- 5:32why. Try answering on your own first and
- 5:35then turn to your class materials or
- 5:36study buddies for verification and
- 5:38further explanation. Second,
- 5:40cross-reference different ideas, even if
- 5:42your professor or class materials didn't
- 5:44explicitly do so. By comparing and
- 5:46contrasting relatable components, you'll
- 5:48better understand the nuances of each,
- 5:50how they interplay, and you'll be less
- 5:52likely to confuse the two. And third,
- 5:55make the content relatable. While
- 5:57elaborating on a concept, relate it to
- 5:58your own life experiences or memories
- 6:01for a stronger memory anchor.
- 6:03Integrating new material with concepts
- 6:05you already know helps you organize the
- 6:07new ideas, thus facilitating recall in
- 6:10the future, such as on test day. Don't
- 6:12be overzealous with your elaboration,
- 6:14meaning keep it within the scope of what
- 6:16is accurate and reasonable.
- 6:18Overextension of elaboration can
- 6:20actually cause further confusion in the
- 6:21long run. Practicing elaboration with
- 6:23smaller groups, such as with the Feynman
- 6:25technique, can be helpful, but beyond
- 6:27three people, the drawbacks begin to
- 6:29outweigh the benefits. Interleaving is
- 6:31the practice of alternating your
- 6:33studying from one topic to another
- 6:35rather than blocking time for only one
- 6:37subject for an extended period of time.
- 6:39The literature suggests that this
- 6:41strategy is particularly helpful with
- 6:43subjects requiring problem-solving, such
- 6:45as physics, chemistry, or math. So, why
- 6:47is this counterintuitively beneficial?
- 6:50Well, interleaving facilitates finding
- 6:52the links, similarities, and differences
- 6:54between ideas. Interleaving simply means
- 6:56you need to switch between topics,
- 6:58ideas, or subjects during a study
- 7:00session. Avoid studying one focused area
- 7:02for too long. As you interleave, it's
- 7:05recommended you approach the topics and
- 7:07subjects in different orders to
- 7:08facilitate improved understanding. While
- 7:10doing so, make it a conscious practice
- 7:12to think how you can link principles
- 7:14between the different concepts. The
- 7:16added benefit that often goes overlooked
- 7:18is one of sustained endurance. When you
- 7:21are strategically shifting between
- 7:23topics, you can ward off burnout and
- 7:25boredom through novel stimuli. I used
- 7:27this practice almost religiously as a
- 7:29medical student to get through study
- 7:31marathons on an almost daily basis.
- 7:34Interleaving requires a bit of
- 7:35calibration. If you spend too little or
- 7:38too much time on a single topic, it can
- 7:40prove detrimental. Switch too often and
- 7:42you begin to face the issues of
- 7:44multitasking, whereby you fail to
- 7:46achieve meaningful deep understanding,
- 7:48and the effectiveness drops. Spend too
- 7:50much time, and you're not interleaving,
- 7:52but rather just performing traditional
- 7:54blocked studying. My recommendation is
- 7:57to perform at minimum one to two
- 7:58Pomodoro blocks before switching to a
- 8:01new topic. At the end of the study
- 8:03session, summarize the relevant key
- 8:04points, but do so in a different order
- 8:06than when you first reviewed the
- 8:08information. Concrete examples are a
- 8:10useful tool in facilitating
- 8:11understanding complex or difficult
- 8:13concepts. It's quite simple. Find
- 8:15relevant examples that illustrate the
- 8:17principles from a lesson you're trying
- 8:18to learn, and ensure you deeply
- 8:20understand how the concrete example is a
- 8:22reflection of this principle in
- 8:24practice. To implement this practice,
- 8:26collect examples, and then explain how
- 8:28the example illustrates the principle
- 8:30you're attempting to learn, and repeat.
- 8:33You can also create your own examples or
- 8:35exchange examples with your study group
- 8:37for added benefit. When practicing this
- 8:39technique, ensure that the examples are
- 8:41actually relevant and accurate to the
- 8:43concept or principle you're studying.
- 8:45Too often, students will find poor
- 8:47examples online, through friends, or
- 8:49from other resources that reinforce an
- 8:51improper understanding. Dual coding is
- 8:54the practice of inputting information
- 8:56related to the same concept through
- 8:57multiple forms of media. For example,
- 9:00you may read about a concept in a
- 9:01textbook, and additionally use visuals
- 9:04and diagrams to drive the point home. To
- 9:06most effectively implement dual coding,
- 9:08don't simply look at a visual and think,
- 9:10"Ah, yes, I know this." But rather
- 9:13actively explain the concept in your own
- 9:15words. Even better, take the information
- 9:17you've read about in a textbook or heard
- 9:19about in lecture, and create your own
- 9:21visuals. This goes back to the summary
- 9:23sheets and synthesis questions I spoke
- 9:25about in my how to take notes video.
- 9:27This will not only prove helpful in the
- 9:29active process of creating the diagram,
- 9:31but now you also have a condensed
- 9:33high-yield visual for future reference.
- 9:35The most common mistake to avoid with
- 9:37dual coding is passively reviewing the
- 9:39various forms of media rather than
- 9:41approaching the practice through active
- 9:43methods. Demonstrate mastery, you should
- 9:46be able to draw necessary figures from
- 9:48memory without cheating and looking at
- 9:50your notes. Understand that these seven
- 9:52principles are not to be practiced in
- 9:54isolation, but rather are interrelated
- 9:57and should be used in conjunction. I
- 9:59refuse to believe the myths that how you
- 10:01do in school or on standardized exams is
- 10:03fixed and based on predetermined
- 10:05intelligence. I believe anyone has the
- 10:07ability to dramatically improve their
- 10:09study techniques, efficiency, and
- 10:11performance on test day. If you need
- 10:13help taking your performance to the next
