Studying online
We’d all like to be able to learn easily. Read something and remember it, listen in on a call and never forget anything, but we all know, well the vast majority of us, that it isn’t always that easy. Over the years and decades many practises have also been developed to help learning, ranging from learning in your sleep to meditative methods. But do these really help?
Well, this is what Shana Carpenter et al. of Iowa State University wanted to find out. To do this they reviewed and analysed over 200 studies ranging over 100 years to find some clear answers. And the results?
The results show that basically two strategies are the most effective and therefore the most important.
These are not sexy new techniques – in fact quite boring. They are spacing and retrieval practice. That’s it!
Spacing is the concept of spacing learning out into more bite-sized chunks. For example, in one study medical students received training on surgery training over three weeks vs. one intensive day. Those in the spaced learning group performed better one week after training had finished but also, importantly, one year later.
I have reviewed spaced, or punctuated, learning previously. I have also reported on brain processes and fatigue during mini learning and break phases (here and here).
The second technique is also a low tech, old-fashioned, and effortful: the technique of learning retrieval. This simply means trying to remember what you have learned. This is the high effort version and probably the one we also try to avoid, particularly when by ourselves. This is more effective than the easy method which is just rereading your notes or the textbook again. The important part seems to be the active retrieval part, actually making an effort to get it out again.
So, this on one hand is a bit boring, no new sexy techniques. It is also really important – two simple techniques will improve learning for anyone and anyone can do it!
So, if learning something new, space it out it bite-sized chunks, and make an effort to remember what you covered and learned.
That’s it, that simple.
Now let’s see if I can remember what I have just written…

Andy Habermacher
Andy is author of leading brains Review, Neuroleadership, and multiple other books. He has been intensively involved in writing and research into neuroleadership and is considered one of Europe’s leading experts. He is also a well-known public speaker, speaking on the brain and human behaviour.
Andy is also a masters athlete (middle distance running) and competes regularly at international competitions (and holds a few national records in his age category).

What Makes Human Brains Different?
Those who have followed my writing and articles will know that this is a question that comes up regularly. Just what is different to human brain compared to other species?
Brain Centre For Altruism Identified
Various parts of the brain have been associated with social behaviour but this particularly interesting study looked at effortful decision-making to help others and identified a region that only activates to this.
Genes Or Exercise for Living Longer?
We all know that we should get our exercise. And we all know that this is associated with many positive health outcomes. This includes living longer.
Yay! “Inoculation” Against Misinformation Effective
Wouldn’t it be great in the current world if we could inoculate people against misinformation. Sigh! But that will never happen
Lack Of Sleep Makes Us Selfish
We humans are a social species, we do things in groups, gather in restaurants, bars, music venues, and public spaces together.
Don’t Try to Change Minds – Change Behaviour
Don’t try to change minds, but simply change behaviour is the result a group of researchers have come to with regard to vaccinations.
