New brain research shows that writing by hand helps children learn more and remember better. At the same time, schools are becoming more and more digital, and a European survey shows that Norwegian children spend the most time online of 19 countries in the EU.
Professor Audrey van der Meer at NTNU believes that national guidelines should be put into place to ensure that children receive at least a minimum of handwriting training.
Results from several studies have shown that both children and adults learn more and remember better when writing by hand.
Now another study confirms the same: choosing handwriting over keyboard use yields the best learning and memory.
“When you write your shopping list or lecture notes by hand, you simply remember the content better afterwards,” Van der Meer says.
Captures the brain’s electricity
Van der Meer and her colleagues have investigated this several times, first in 2017 and now in 2020.
In 2017, she examined the brain activity of 20 students. She has now published a study in which she examined brain activity in twelve young adults and twelve children.
This is the first time that children have participated in such a study.
Both studies were conducted using an EEG to track and record brain wave activity. The participants wore a hood with over 250 electrodes attached.
The brain produces electrical impulses when it is active. The sensors in the electrodes are very sensitive and pick up the electrical activity that takes place in the brain.
Handwriting gives the brain more hooks to hang memories on
It is a little slower to write by hand, but it is important that children go through the tiring phase of learning it,
says Professor Audrey van der Meer at NTNU.
The results showed that the brain in both young adults and children is much more active when writing by hand than when typing on a keyboard.
“The use of pen and paper gives the brain more ‘hooks’ to hang your memories on. Writing by hand creates much more activity in the sensorimotor parts of the brain. A lot of senses are activated by pressing the pen on paper, seeing the letters you write and hearing the sound you make while writing. These sense experiences create contact between different parts of the brain and open the brain up for learning. We both learn better and remember better,” says Van der Meer.
Digital reality a big part of European children’s lives
She believes that her own and others’ studies emphasize the importance of children being challenged to draw and write at an early age, especially at school.
Today’s digital reality is that typing, tapping and screen time are a big part of children’s and adolescents’ everyday lives.
A survey of 19 countries in the EU shows that Norwegian children and teens spend the most time online. The smartphone is a constant companion, followed closely by PCs and tablets.
The survey shows that Norwegian children ages 9 to16 spend almost four hours online every day, double the amount since 2010.
Kids’ leisure time spent in front of a screen is now amplified by schools’ increasing emphasis on digital learning.
Van der Meer thinks digital learning has many positive aspects, but urges handwriting training.
National guidelines needed
“Given the development of the last several years, we risk having one or more generations lose the ability to write by hand. Our research and that of others show that this would be a very unfortunate consequence” of increased digital activity, says Meer.
She believes that national guidelines should be put in place that ensure children receive at least a minimum of handwriting training.
“Some schools in Norway have become completely digital and skip handwriting training altogether. Finnish schools are even more digitized than in Norway. Very few schools offer any handwriting training at all,” says Van der Meer.
In the debate about handwriting or keyboard use in school, some teachers believe that keyboards create less frustration for children. They point out that children can write longer texts earlier, and are more motivated to write because they experience greater mastery with a keyboard.
Important to be outside in all kinds of weather
“Learning to write by hand is a bit slower process, but it’s important for children to go through the tiring phase of learning to write by hand. The intricate hand movements and the shaping of letters are beneficial in several ways. If you use a keyboard, you use the same movement for each letter. Writing by hand requires control of your fine motor skills and senses. It’s important to put the brain in a learning state as often as possible. I would use a keyboard to write an essay, but I’d take notes by hand during a lecture,” says Van der Meer.
Writing by hand challenges the brain, as do many other experiences and activities.
“The brain has evolved over thousands of years. It has evolved to be able to take action and navigate appropriate behaviour. In order for the brain to develop in the best possible way, we need to use it for what it’s best at. We need to live an authentic life. We have to use all our senses, be outside, experience all kinds of weather and meet other people. If we don’t challenge our brain, it can’t reach its full potential. And that can impact school performance,” says Van der Meer.

Neuronal circuits for fine motor skills
Writing, driving a screw or throwing darts are only some of the activities that demand a high level of skill. How the brain masters such exquisite movements has now been described in the journal “Nature” by a team of researchers at the University of Basel and the Friedrich Miescher Institute for Biomedical Research. A map of brainstem circuits reveals which neurons control the fine motor skills of the arm and hand.
Picking up a pen and writing our name or reaching for a fork to eat spaghetti with tomato sauce are things we take for granted. However, holding a pen properly or bringing spaghetti to the mouth without making a mess requires precise arm movements and a high level of skill.
Underlying all our motor behavior is a perfect interplay between neurons in the brain, the spinal cord, and the muscles. But which neuronal circuits control the fine motor skills of the arms, hands and fingers? Prof. Silvia Arber’s team has been addressing this question in recent work. The neurobiologists who work at both the Biozentrum of the University of Basel and at the Friedrich Miescher Institute for Biomedical Research (FMI) have been investigating how the nervous system controls motor behavior for many years.
Neurons in the brainstem control fine motor skills
Using a mouse model, the researchers have been able to demonstrate that a specific region of the brainstem is responsible for various fine motor activities of the forelimbs. For their investigations they applied so-called optogenetic and viral methods in order to mark neurons and observe their activity. This enabled the team to localize four neuronal subpopulations in this region and correlate with specific functions. For example, one group of neurons was able to elicit forelimb reaching, while another group controls handling of the food.
In terms of evolution, the brainstem is the oldest part of the brain and is the direct extension of the spinal cord. The brainstem is an important switchboard between higher order movement planning centers in the brain and the executive circuits in the spinal cord. In the spinal cord, information streams about movement ultimately reach motor neurons that are directly connected to muscles cells. These in turn control movement through contraction. It has only recently been discovered that the brainstem consists of many areas containing functionally specialized neuronal populations, engaged with the control of diverse forms of body movements.
Map of brainstem circuits for fine motor skills
In their study, Arber’s team has defined the organization of the neurons in one of those brainstem regions called the “lateral rostral medulla» (latRM) and traced their communication pathways. This enabled the researchers to associate different behavioral activities with specific groups of latRM neurons. “Relatively simple forelimb actions such as reaching for food are accomplished by latRM neurons with direct projections to the spinal cord,” explains the first author Ludwig Ruder.
Executing more complex forelimb movements, which also involve the fingers, i.e. grasping or bringing a piece of food to the mouth, are controlled by latRM neurons with connections to neurons in other brainstem regions. “The connections and circuits within the brainstem are indispensable for more complex motor skills,” says Arber. “The neuronal populations we identified in the latRM very specifically control motor skills of the forelimbs. Notably, the generation of complex and precise forelimb movements such as throwing, grasping or writing require the communication between different brainstem regions.“
Control of motor actions is similar in man and animals
The division of neuronal populations according to different forms of movements based on spatial organization and connectivity provides insights into the function of the brainstem and the control of motor behavior, in this case fine motor skills of the arm and hand. Many neuronal circuits of the brainstem are similar in humans and animals. It is therefore possible to hypothesize which neuronal populations control which movements or how diseases or injury may impair fine motor skills or other behaviors in humans.
