New d-ELP Database Launched to Enhance Children’s Reading Skills

Researchers at the Florida Center for Reading Research (FCRR) have launched a new online resource aimed at improving literacy among children in grades 1 through 5. The development English Lexicon Project (d-ELP) features data on 9,961 of the most frequently printed English words, providing critical insights into reading difficulties faced by young learners.

The d-ELP is an open-access database designed to serve a variety of stakeholders, including educators, researchers, curriculum developers, and policymakers. According to Donald Compton, Director Emeritus of FCRR and the lead researcher, “English is a particularly hard language to learn. Some words are simply harder for children to learn to read than others.” This project aims to bridge the gap in understanding the factors contributing to reading difficulties.

Understanding the Challenges of Learning to Read

Learning to read in English presents unique obstacles due to its complex spelling patterns and varied orthography. Even proficient young readers struggle with certain words, such as “suede” and “yacht.” Prior to the introduction of the d-ELP, educators have lacked a comprehensive resource to address these challenges effectively.

The database offers continuous Item Response Theory (IRT)-based estimates of word reading difficulty, along with extensive raw trial-level data. Teachers and caregivers can access lists of words categorized by characteristics like vowel combinations or sound blends. This feature enables them to create tailored spelling lists and instructional materials suited to each child’s reading proficiency.

Data for the d-ELP was collected from 1,907 children across various sites in the United States. Each child read lists of 250 to 500 words, specifically selected to match their reading level. This methodology ensures a diverse range of word difficulties is represented, focusing on words that are developmentally appropriate.

Empowering Educators and Supporting Literacy Development

The d-ELP database addresses a critical need by providing a searchable, data-driven tool to explore word-level reading challenges. This resource is expected to facilitate targeted instruction, allowing educators to adapt their teaching methods to better align with each child’s developmental stage. Furthermore, the database aids in developing instruction that promotes generalization of word reading and decoding skills.

With the launch of the d-ELP, educators now have a powerful tool at their disposal to better understand student needs and accelerate the translation of research into practical teaching strategies. The database is readily available for public, noncommercial use. Users can easily search for word difficulty ratings and related statistics through an intuitive online search engine.
