The process Step by Step
Step 1: The Assessment
The Lexplore assessment can be conducted on any computer while an eye tracker records the student’s eye movements. Everything is documented digitally, so no manual work is required.
A student reads the letters that they see on the screen out loud and then they are asked to read two short grade level passages. The passages vary so a student never reads the same text twice. This prevents the student from remembering or practicing specific text.
The student is asked a few comprehension questions. The assessment is administered individually and questions will be given verbally and recorded. The questions are open ended and not multiple-choice, to reduce the risk of the child being able to give a correct answer by merely guessing.
The entire process is completed in about 2 minutes.
It is recommended that students who fall below the expected national average be assessed at least every four months to ensure they are progressing and receiving the proper interventions for growth. Students who read on grade level or above should only be assessed once per academic year to ensure they are developing appropriately as well.
Step 2: The Analysis
The data collected from the assessment is uploaded to a cloud-based platform for analysis. Lexplore researchers developed the analysis method based on artificial intelligence (AI) and machine learning (ML).
Lexplore tracks how the eyes move while reading. The immediate data collected reflects the cognitive processes in the brain. Lexplore’s analysis is adjusted depending on the student’s grade level and the quarter of the school year in which the assessment is administered. The information gather is analyzed based on thousands of recorded eye movements and a battery of other established tests and assessments such as rapid automatized naming, word strings, and reading of nonsense words and real words.
Lexplore’s rapid reading assessment has been standardized based on thousands of children aged 7-10 years. When Lexplore measures an individual student’s reading ability, the assessment pertains not only to the student’s eye movements but it also indirectly evaluates how the student would perform on other tests that assess word decoding ability.
It is also important to note that there is no single parameter or trait in eye movements that determines how Lexplore’s models assess a student’s reading ability. Rather, it is a combination of several different parameters, which together reflect the cognitive process taking place as the student reads that determines the student’s results.
Step 3: The Results
Teachers are able to access the Students’ Results via the Lexplore web portal. In addition, a teacher can compare the student against other students in their class, school or across the district.
Lexplore’s method enables comparisons over time and between different groups. The results are clearly presented on several different levels — individual, class, school and/or school district. The objective results help schools and districts make well-informed decisions regarding allocation of resources and types of intervention.
Lexplore uses five levels to describe reading ability: (1) Low , (2) Below average, (3) Average (4) Above average, and (5) High. The reading level indicates a student’s current reading ability, and immediately provides the teacher with valuable information regarding which students need extra support or remediation.
Lexplore’s reading levels are distributed based on a normal distribution curve. Different degrees of support or stimulation are recommended depending on each student’s reading level.
