The process Step by Step

Step 1: The Assessment


To use Lexplore, you’ll simply plug in an eye tracker and external monitor to your computer, and download the Lexplore app. The assessment includes a RAN (Rapid Automized Naming) test, and two short passages. There are 8 passages available for each grade level, so your students will never read the same passage twice. After a student reads each passage (aloud or silently), you will verbally ask the student 2 or 3 comprehension questions. These questions are open-ended and act as a “retell” of the short passage. You simply click on a button to indicate if the student answered correctly.

The entire process is completed  in about 3 minutes. You can test each student up to 4 times each year. You can get detailed instructions from one of our favorite Lexplorers, Lydiana, through our video series in the “Knowledge Base.”

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 time of the school year when you assessed the student. The information gathered 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 processes taking place as the student reads that determines his/her results.

Step 3:  The Results


You can access the students’ results via the Lexplore web portal.  In addition, you can compare each student against other students in the 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 you 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.
