Students are neither left nor right brained: How some early childhood educators get this 'neuromyth' and others wrong

Many teachers and parents know neuroscience, the study of how the brain functions and develops, is important for children's education.

Brain development is as part of teacher education in universities. Neuroscience is even mentioned in Australia's "", which guides early childhood programs.

Previous research has shown there are misunderstandings about how neuroscience works (or "neuromyths") among teachers both in and .

Our shows there are also some widespread neuromyths among early childhood educators.

What are the myths? And what does the evidence say?

Our research

We surveyed more than 520 Australian early childhood educators in 2022 to understand their neuroscience knowledge.

We chose to study early childhood educators because there is a research gap in our understanding of those teaching and caring for younger children. The surveys were distributed online via multiple channels including email lists, social media and professional associations.

About 74% of respondents worked in a long daycare or a preschool/kindergarten (educating children in the final years before formal school). About 63% had either a bachelor's degree or postgraduate qualification.

Our findings

We asked respondents whether various false statements were true, in order to assess their level of knowledge about neuroscience. The average correct score was 13.7 out of 27.

Some myths presented in our study were widely, and correctly, understood to be false. For example, more than 90% of respondents correctly identified "" and "mental capacity is solely hereditary and or experience" as untrue.

But for other myths, most respondents were either unsure or believed the statement to be correct. For example:

• only 7% of respondents correctly identified "teaching to different learning styles will improve learning" as false.
• only 15% of respondents correctly identified "students are either left or right brained" as false.

This suggests educators need more evidence-based neuroscience content as part of their professional education and development. While some neuromyths may seem harmless, others can have real implications for teaching decisions and student learning.

What is the problem with these neuromyths?

Myth 1: 'Teaching to different learning styles will improve learning'

The idea of learning styles . This argued students will show improved learning if they receive information in a very specific way. For example, "visual learners" need to see information to be able to learn, while "aural learners" need to hear it.

This has as a myth since the mid-2000s, but the idea of learning styles still persists .

While people may have preferred ways of accessing information, there learning suffers if information isn't provided in this format. Research teachers' ideas of a student's learning style do not tend to match students' self-reported preferences.

So teaching decisions made on assumed student "learning styles" may be flawed in any case.

Myth 2: 'Students are either left or right brained'

Another is we have personality traits that are either right-brained (intuitive and creative) or left-brained (analytical and logical)

There is evidence some brain functions . For example, and . However, there's your personality or your aptitude comes particularly from the left or right brain hemisphere.

The harm in this myth comes from students thinking they are "more left-brained than right" and teachers reinforcing this view. And from here, young people might think they should just stick to humanities or just stick to math or science.

This could rob a student of exploring multiple academic and career paths. Sure, some students will seem to really flourish as an artist, some as mathematicians and some as both. But we should not be labeling students, based on a neuromyth, potentially impacting self-confidence and their potential.
