The Research

Our unique assessment method has been developed following over 30 years of scientific research, looking at how eye movements can offer a new insight into reading as a complex cognitive and linguistic processes, instead of a simple percentile or score.

Our assessment method, invented in January 2013, is based upon data from the Kronoberg project; an entirely unique longitudinal study of reading and writing which began almost 30 years ago at the Karolinska Institute in Stockholm. As part of the project, eye movement recordings were taken for hundreds of children, both with and without reading difficulties. Their academic and reading progress was then followed from year 3 to adulthood.

By analysing eye movement patterns from this study combined with additional research from the Dyslexia Project in the Swedish municipalities of Järfälla and Trosa, 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. The cumulative results from their work were published in PLoS One (Benfatto et al., 2016).

” Eye movements provide one of the best ways to measure reading ability at an incredibly in-depth level. “

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. You can find out more by watching our fantastic research film below.

By studying a child’s spontaneous eye movements as they read, our assessment can precisely determine their reading attainment and highlight potential difficulties from minor differences in the way they process text. Having conducted over 200,000 tests across the globe, analysis by our latest machine learning model is now carried out with an accuracy of over 97 %.

Unlike many other assessments, the large amount of data we have aggregated over time means that we can now offer an insight into reading that takes into account the natural, weekly reading development children are likely to make throughout the academic year.

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 spend their time doing what they do best – supporting their pupils.

To find out how you can utilise the benefits of technology in the classroom by combining new advances with the ‘human touch’ of good teachers download our FREE AI -Guide.

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. They offer the largest range of medical courses in Sweden and since 1901 their Assembly has selected the Nobel laureates in Physiology or Medicine.

The researchers and founders behind Lexplore Analytics still carry out their work at the Marianne Bernadotte Centre within the Institute today.

More about the research

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 they process text.

 “Eye movements is one of the best ways to index reading ability at an incredibly in-depth level.” 

Julie Kirkby – Professor in Psychology at Bournemouth University

Our Eye tracking assessment has been developed following over 30 years of peer-reviewed research at one of the leading medical institutes in the world into the unique insight eye movements can offer us into reading.

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 pupil, depending upon their reading speed. This enables schools to quickly assess a large number of pupils without additional workload. The results are available immediately in our user-friendly portal with no marking required.

 ” One of the main reasons we chose Lexplore is because it frees up so much time. Previously, it took teachers an entire term to do accurate assessments on their whole class. By contrast, 200 children went through the Lexplore assessment process in a week. Within five minutes of each assessment, we had the results of their reading activity and an accurate attainment level.”

Lexplore Testimonials

Adam Luxford

Data Protection Officer • Freemantle C of E Community Academy

” Thanks to Lexplore we now have a rigorous and quick method of assessing children’s reading ability. We can assess children without adding to the work load of class teachers, with the intention of providing effective interventions without creating unnecessary admin.

We will be able to quickly and confidently identify problem areas where interventions may be necessary. Lexplore has also given us the tools for tracking the progress of interventions overtime.

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

“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.”
