“Another nail in the coffin for learning styles” – students did not benefit from studying according to their supposed learning style
The idea that we learn better when taught via our preferred modality or “learning style” – such as visually, orally, or by doing – is not supported by evidence.
The idea that we learn better when taught via our preferred modality or “learning style” – such as visually, orally, or by doing – is not supported by evidence. Nonetheless the concept remains hugely popular, no doubt in part because learning via our preferred style can lead us to feel like we’ve learned more, even though we haven’t.
Some advocates of the learning styles approach argue that the reason for the lack of evidence to date is that students do so much of their learning outside of class. According to this view, psychologists have failed to find evidence for learning styles because they’ve focused too narrowly on whether it is beneficial to have congruence between teaching style and preferred learning style. Instead, they say psychologists should look for the beneficial effects of students studying outside of class in a manner that is consistent with their learning style.
For a new paper in Anatomical Sciences Education, a pair of researchers at Indiana University School of Medicine have conducted just such an investigation with hundreds of undergrads. Once again however the findings do not support the learning styles concept, reinforcing its reputation among mainstream psychologists as little more than a myth.
At the start of term, Polly Husmann and Valerie Dean O’Loughlin asked hundreds of undergrads on an anatomy course (which involved lectures and practical lab classes) to take one of the most popular online learning styles surveys, the VARK. Taken by millions of people worldwide, the VARK categorises students according to how much they prefer to learn visually, via auditory information, through reading and writing, or through kinaesthetics (by doing or by practical example).
The VARK website also offers study tips based on your supposed preferred learning style(s). The researchers encouraged their student participants to take the survey and to adopt the study practices consistent with their dominant learning style. Later in the term, the researchers surveyed them about the methods they’d actually used when studying outside of class, to see if they used methods in line with their supposed dominant learning style. Finally, the researchers accessed the students’ end-of-year grades to see if there was any association between grade performance, dominant learning style, and/or studying outside of class in a way consistent with one’s dominant learning style.
The results are bad news for advocates of the learning styles concept. Student grade performance was not correlated in any meaningful way with their dominant learning style or with any learning style(s) they scored highly on. Also, while most students (67 per cent) actually failed to study in a way consistent with their supposedly preferred learning style, those who did study in line with their dominant style did not achieve a better grade in their anatomy class than those who didn’t.
Instead, there were specific study strategies, such as practising microscope work and using lecture notes, that were associated with better grade performance, regardless of students’ learning style. Other activities, such as using flash cards, were associated with poorer performance, perhaps because they were a sign of learning by rote rather than deeper learning.
Husmann and O’Loughlin don’t pull any punches in their conclusion. Their findings, they write – especially when considered in the context of past research – “provide strong evidence that instructors and students should not be promoting the concept of learning styles for studying and/or for teaching interventions. Thus, the adage of ‘I can’t learn subject X because I am a visual learner’ should be put to rest once and for all.”
Ever since we've had the technology, we've looked to the stars in search of alien life. It's assumed that we're looking because we want to find other life in the universe, but what if we're looking to make sure there isn't any?
Here's an equation, and a rather distressing one at that: N = R* × fP × ne × f1 × fi × fc × L. It's the Drake equation, and it describes the number of alien civilizations in our galaxy with whom we might be able to communicate. Its terms correspond to values such as the fraction of stars with planets, the fraction of planets on which life could emerge, the fraction of planets that can support intelligent life, and so on. Using conservative estimates, the minimum result of this equation is 20. There ought to be 20 intelligent alien civilizations in the Milky Way that we can contact and who can contact us. But there aren't any.
Frequent shopping for single items adds to our carbon footprint.
- A new study shows e-commerce sites like Amazon leave larger greenhouse gas footprints than retail stores.
- Ordering online from retail stores has an even smaller footprint than going to the store yourself.
- Greening efforts by major e-commerce sites won't curb wasteful consumer habits. Consolidating online orders can make a difference.

This is especially relevant to the "last mile" GHG footprint: the distance between the distribution center and the consumer.</p><p>Interestingly, the smallest GHG footprint occurs when you order directly from a physical store—even smaller than going there yourself. Pure players, such as Amazon, are the greatest offenders. Variables like geographic location matter; the team looked at shopping in the UK, the US, China, and the Netherlands. </p><p>Sadegh Shahmohammadi, a PhD student at the Netherlands' Radboud University and corresponding author of the paper, <a href="https://www.cnn.com/2020/02/26/tech/greenhouse-gas-emissions-retail/index.html" target="_blank">says</a> the above "pattern holds true in countries where people mostly drive. It really depends on the country and consumer behavior there."</p><p>The researchers write that this year-and-a-half long study pushes back on previous research that claims online shopping to be better in terms of GHG footprints.</p><p style="margin-left: 20px;">"They have, however, compared the GHG emissions per shopping event and did not consider the link between the retail channels and the basket size, which leads to a different conclusion than that of the current study."</p><p>Online retail is where convenience trumps environment: people tend to order one item at a time when shopping on pure player sites, whereas they stock up on multiple items when visiting a store. Consumers will sometimes order a number of separate items over the course of a week rather than making one trip to purchase everything they need. </p><p>While greening efforts by online retailers are important, until a shift in consumer attitude changes, the current carbon footprint will be a hard obstacle to overcome. Amazon is trying to have it both ways—carbon-free and convenience addicted—and the math isn't adding up. If you need to order things, do it online, but try to consolidate your purchases as much as possible.</p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.
