The Research

Our method has been developed following 30 years of scientific research looking at how eye movements can offer a unique into those complex cognitive processes involved with reading that we can often struggle to understand.

This research was undertaken at the Karolinska Institute, provider of the Nobel Prize in medicine, as part of the Kronobergs Project. This completely unique study examined the eye movements of around 100 children, both with and without reading difficulties, from year 4 until adulthood.

By analysing eye movement patterns from this study, our researchers and founders Gustaf Öqvist Seimyr and Mattias Nilsson Benfatto were able to show that the statistical models they had developed could accurately predict which students would experience difficulties after as little as 30 seconds of reading.

For a child with high reading attainment (left), their eyes generally move through a passage of text with short, quick movements, whereas for a child with lower reading attainment (right) their eyes tend to move much slower, and they may fixate upon individual words or regress.

By studying a child’s spontaneous eye movements as they read, our assessment can precisely determine their individual reading attainment by picking up on minor differences in the way their brain’s process text. This also helps identify those experiencing difficulties, such as Dyslexia, at a much earlier stage of their development.

Frequently Asked Questions...

Will AI technology replace our teachers and SENCOs?

Whist our algorithms are extremely powerful they will never be a substitute for a good teacher! Our technology simply helps free up valuable resources so teachers can sped their time doing what they do best – supporting their pupils.

What is the Karolinska Institute?

The Karolinska Institute is not only Sweden’s largest centre of medical academic research, but also one of the world’s foremost medical universities. Within Sweden they offer the largest range of medical courses, and since 1901 their Assembly has selected the Nobel laureates in Physiology or Medicine.

How do eye movements reflect reading attainment?

Reading involves a complicated interplay between many different cognitive and linguistic processes. Measuring when, where, and how a child’s eyes move in relation to the words they read allows us to quickly evaluate how effectively these processes work together, and pick up on minor differences in the way their brains process text on lexical, syntactic and structural levels.

 

How do teachers become certified examiners?

As a Lexplore Customer, we will visit your school or organisation to carry out the theoretical and practical Training needed for your staff members to test children independently. The technology and method is extremely simple to set up and understand meaning the training process is usually completed in one or two days.

How long does the Lexplore assessment take?

We estimate that the assessment takes between two and five minutes per child depending upon their reading speed. This enables schools to quickly assess a large number of pupils without additional workload.

At what age can a child sit the Lexplore assessment?

At the minute we only assess children from years 2 to year 5, however, we plan to extend this once we have trained our machine learning models to analyse the reading attainment of older children with the same level of precision.

Lexplore Testimonials

IT Lead

Adam Luxford • Freemantle C of E Community Academy

“Thanks to Lexplore we now have a rigorous and quick method of assessing children’s reading ability and the methods they use in order to decode text. We can assess children without adding to the work load of the class teachers, with the intention of also providing effective interventions for the teachers again without creating unnecessary admin.

We will be able to quickly and confidently identify problem areas where interventions may be necessary working in depth on the pedagogies of reading. Lexplore has given us the tools for tracking the progress of these interventions over time displaying it in a very tangible way.

The process of screening pupils could not be easier and often is a very enjoyable experience for the pupils. The training is very thorough and contact with the company is easy and available at all times if any questions or problems should occur. 

The portal is very clear, straight forward and is easy to use and understand. The data is displayed in a very visual manner giving an overview at a glance. Being able to see the child’s eye movements has been fascinating, insightful and at times mesmerising. The assessment has helped highlight students with optical impairments or pupils that may require reading glasses, based on their eye movement.

I feel that our knowledge of what makes a ‘strong’ reader has really been improved thanks to the scientific methods used by Lexplore.”

“We have found the results of the screening confirm and back-up other assessments that we carry out in school as well as highlighting some children (particularly girls and those who use coping strategies to present as confident readers) who may have a reading difficulty that has not previously been recognised.

The screening process is quick, straightforward and easy to manage within the normal day-to-day organisation of school. The presentation of results is clear, visual and easily accessible both with regard to whole class/ school outcomes and individual results. We especially like the ability to watch the actual recording of eye-movement whilst hearing the child read aloud.

We are impressed by the privacy of the results which require appropriate security measures to access. The results have enabled us to plan more targeted intervention and adapt quality first teaching to meet the needs of all children.

We are planning to use the results within forthcoming transition meetings between class teachers. Feedback from children was really positive and they are looking forward to the next screening sessions.”
