Studying Disasters – Study Methods I Avoid At All Costs10 min read
I remember my first notebook from 1st grade. It was a glorious, black, lined piece of stationery. It settled perfectly next to my pencil case inside my classy Jansport backpack. If only I knew how useless that notebook was. If only I knew that there were study strategies that took less time and were much more effective. If only I knew most study strategies we were taught in school were a waste of time.
In this post, I’ll go over the 8 biggest studying mistakes. Study methods I avoid at all costs.
Inside that fancy pencil case glowed the classic yellow highlighter, a staple of any well-respected first grader’s armory. Bolded words stood no chance for 6-year-old Zach’s fantastic highlighting abilities! Textbooks and knowledge, beware! Right?
Well, a review article from 2013 looked at ten learning techniques. They gave the methods a rating of either low, moderate, or high utility based on students’ performance when using those strategies.1
Let’s start with highlighting:
On the basis of the available evidence, we rate highlighting […] as having low utility. In most situations that have been examined and with most participants, highlighting does little to boost performance.Dunlosky et al.
Importantly, for the remainder of the methods discussed and highlighting, this review study looks at many different research studies to come up with their conclusions. They are comparing the results of the ten other study techniques.* In the reviewed studies, highlighting occasionally had significant results compared to nothing. However, highlighting is inferior to other study techniques, such as practice testing and spaced repetition. And not just medium or “so-so,” it’s rated as low utility.
Avoid highlighting at all costs.
Well, underlining is different, right? Highlighting, maybe I am just using it because I want to see the pretty yellow color. With underlining, it’s more adult, more mature. I would only underline important things. Right? Insert buzzer sound here.
On the basis of available evidence, we rate highlighting and underlining as having low utility.Dunlosky et al.
Two groups of students were asked to read and understand a text in one study. One group was told to underline themselves, while the other group was given experimenter-generated underlining, so the underlining was done for them.2
Subjects who generated their own underlining did not perform significantly better than those who were given experimenter-generated markings.Nist & Hogrebe
Darn it! 7-year-old Zach loses again.
And you’ll say, wait for a second, Zach, don’t we summarize using the Feynman technique? And I would say “yes” and “no.” Importantly, summarizing can be done without understanding the information you are looking at. I remember, for example, occasionally summarizing a lecture by the title and listing the definition of all the bolded words; that isn’t a summary; that’s poppycock (now, when’s the last time you heard that word?).
The Feynman technique uses self-explanation and elaborative interrogation rated as a medium utility in this review paper. The Feynman technique isn’t just summarizing.
However, summarizing receives the ranking of low utility. According to the researchers, it may benefit those adept at summarizing, but most people are not.1
we rate summarization as low utility. It can be an effective learning strategy for learners who are already skilled at summarizing; however, man learners […] will require extensive training, which makes this strategy less feasible.Dunlosky et al.
Again, summarizing may be helpful to some, but compared to other study methods, the time spent on summarizing is not worth it.
I remember my AP psychology class in high school. I thought the only way to prepare for the test was to read and re-read the chapters multiple times until the information stuck in my head. What happened, however, was my mind glazed over. I was flipping pages with nothing sinking into my brain.
The problem with rereading is it’s extremely time-intensive and a form of passive learning.
The relative disadvantage of rereading to other techniques is the largest strike against rereading and is the factor that weighted most heavily in our decision to assign it a rating of low utility.Dunlosky
The initial reading of the chapter may be helpful, but nothing beyond that. Because I know many of my friends and people watching this video still use rereading, I want to present another journal’s analysis of rereading.3
Basic research on human learning and memory has shown that practicing retrieval of information (by testing the information) has powerful effects on learning and long-term retention. […] Repeating reading […] confers limited benefit beyond that gained from the initial reading of the material.Karpicke & Roeriger
If you still don’t believe me, I suggest you go to PubMed or google scholar and search “effectiveness of summarizing.”
Rereading is a form of passive learning, stop it and replace it with practice testing; you will save time and score better on your exams.
5. Rewatching or Relistening
Other forms of passive learning include rewatching or relistening; why should these be any different than rereading? They aren’t.
In one study, 102 first-year pharmacy students were tested in lectures after being told to study in two different ways. One way was self-testing, and the other was re-watching lectures. Here is the conclusion of their paper:4
Testing may be more efficient (ie, cost-effective) for long-term performance. Students who attend class may want to avoid rewatching course recordings in favor of practice testing.Palmer et. al.
However, if you don’t attend lectures, you should still watch the lecture once because that watch will be your first time viewing the material. Rewatching that same lecture, however, is a waste of time.
I did not see evidence for relistening, so this is a Zach hypothesis. But why should it be any different than rewatching or rereading? I almost think it is likely the worst of the three (rereading, rewatching, or relistening) because of how passive it is.
Watch or listen to something once. Don’t rewatch it, don’t relisten to it. Simply eliminating these study strategies can save you about 3x as much time and help you achieve the same or better scores when you switch to active recall techniques.4
Sleep, proper diet, and exercise. If you don’t have those three things in order, it becomes increasingly difficult to get the other aspects of your life in order. Sleep is the most important of these three.
Sleep is a magical force multiplier to everything you do, your weights in the gym, your happiness levels versus depression, and your ability to study and retain information.5,6
People who sleep and study less vs. those who don’t sleep and study more perform better on exams. Once you go under 7 hours of sleep, your performance and health drop, no matter your age.7
Don’t pull all-nighters. The evidence does not back poor sleep, and an all-nighter the night before an exam will lower your scores.
7. No Plan
Abraham Lincoln famously said,
Give me six hours to chop down a tree and I will spend the first four sharpening the axe.Abraham Lincoln
Now, I’m not suggesting sharpening your pencil for four hours; do people even sharpen pencils anymore? Anyway, what I am suggesting is planning what you will study. A huge mistake is showing up at the library with the plan to “study for the test.” Not only will that make you more likely to procrastinate, but you will also lose precious brain power to figure out what to study.
Be as specific as possible with your plans to study; what chapters will you be looking at? How will you be looking at them? Practice questions? Flashcards? How long will you spend on each chapter? How long will you spend in the library?
8. No Breaks
People who take breaks have better cognitive performance.8,9
A new systematic review and meta-analysis on the efficacy of micro-breaks were just published in August of 2022 by a reasonably highly respected journal. In it, they conclude,
Overall, the data support the role of micro-breaks for well-being, while for performance, recovering from highly depleting tasks may need more than a 10-minute breaks.Albulesco et al.
They also concluded that micro-breaks positively impacted well-being by enhancing vigor and lowering fatigue, regardless of contextual factors.
My favorite method of taking breaks is the Pomodoro method. I study for 25 minutes at a time and then take a 5-minute break. This is repeated four times, and on the fourth time, I take a 30-minute break. Another timing increment I like is 50/10. So 50 minutes of work followed by a 10-minute break. Two cycles and the second cycles break 30 minutes instead of 10.
Overall, limit or eliminate all of the above, and you are well on your way to becoming a better student.
*Of note the only “high utility” study strategies were practice testing and distributed practice. Items of medium utility were: elaborative interrogation, self-explanation, and interleaved practice.
