Learning physics may activate new brain areas
New York, May 25: Brain areas that are traditionally not associated with learning science can become active when people are confronted with solving physics problems, finds a study.
This shows that the brain's activity can be modified by different forms of instruction.
"The neurobiological processes that underpin learning are complex and not always directly connected to what we think it means to learn," said lead author Eric Brewe, Associate Professor at Drexel University in Pennsylvania, US.
The findings, published in the journal Frontiers in ICT, showed that newer brain regions associated with attention, working memory and problem solving -- the lateral prefrontal cortex and parietal cortex, sometimes called the brain's "central executive network" - showed activity when dealing with such problems.
Another area that became active was the posterior cingulate cortex, which is linked to episodic memory and self-referential thought.
"These changes in brain activity may be related to more complex behavioural changes in how students reason through physics questions post- relative to pre-instruction," Brewe noted.
"These might include shifts in strategy or an increased access to physics knowledge and problem-solving resources," he said.
Using fMRI (functional magnetic resonance imaging) to measure blood flow in the brain, the researchers looked to map what areas become active when completing a physics reasoning task, both before a course on the concepts and after.
A small group of students were taught a physics course that utilised "Modeling Instruction," a style of teaching which encourages students to be active participants in their learning.
"This suggests that learning physics is an imaginative process, which is not typically how people think of it," Brewe said, in reference to the study which aimed to further explore how students use their own mental models to understand new concepts.
"The idea of mental models is something that people who research learning love to talk about, but have no evidence of what is happening inside brains other than what people say or do," Brewe said.
"We are actually looking for evidence from inside the brain."

London, Nov 22: A bomb disposal squad deployed as a “precaution” to the South Terminal of Gatwick Airport concluded an investigation into a "security incident" on Friday after making a “suspect package” safe.
The South Terminal of Gatwick Airport, the UK's second busiest airport after Heathrow, which was briefly shut owing to the incident reopened following the incident.
The Gatwick is around 45 km south of London.
Two people detained during the enquiries have since been allowed to continue their journey as the airport was opened.
“Police have concluded their investigation into a report of a suspect package at Gatwick Airport. Officers from the EOD (Explosive Ordnance Disposal) team made the package safe, and the airport has been handed back to its operator,” Sussex Police said in an updated statement.
“Two people detained while enquiries were ongoing have subsequently been allowed to continue their journeys. There will remain an increased police presence in the area to assist with passengers accessing the South Terminal for onward travel,” the statement added.
Earlier on Friday, the incident caused severe disruption at the busy airport’s South Terminal, while the North Terminal of Gatwick Airport remained unaffected.
“Police were called to the South Terminal at Gatwick Airport at 8.20 am on Friday (November 22) following the discovery of a suspected prohibited item in luggage,” a Sussex Police statement said.
“To ensure the safety of the public, staff and other airport users, a security cordon has been put in place whilst the matter is dealt with. As a precaution, an EOD (Explosive Ordnance Disposal) team is being deployed to the airport. This is causing significant disruption and some roads around the South Terminal have been closed. We’d advise the public to avoid the area where possible,” it said.
Footage on social media taken outside the airport showed crowds of frustrated travellers being moved away from the terminal building.
Gatwick said it was working hard to resolve the issue.
“A large part of the South Terminal has been evacuated as a precaution while we continue to investigate a security incident," the airport said in a social media post.
“Passengers will not be able to enter the South Terminal while this is ongoing. The safety and security of our passengers and staff remain our top priority. We are working hard to resolve the issue as quickly as possible.”
Train and bus services that serve the airport were also impacted while the police carried out their inquiries.
In an unrelated incident in south London on Friday morning, the US Embassy area in Nine Elms by the River Thames was the scene of a controlled explosion by Scotland Yard dealing with what they believe may have been a “hoax device”.
“We can confirm the 'loud bang' reported in the area a short time ago was a controlled explosion carried out by officers,” the Metropolitan Police said in a post on X.
“Initial indications are that the item was a hoax device. An investigation will now follow. Some cordons will remain in place for the time being but the majority of the police response will now be stood down,” it added.
