A new online resource aimed at enhancing elementary-level reading skills has been launched by the Florida Center for Reading Research (FCRR) at Florida State University (FSU). The development English Lexicon Project (d-ELP) provides access to word reading data on 9,961 of the most frequently printed English words for children in grades 1 through 5.
The d-ELP database is designed to assist a variety of stakeholders, including educators, researchers, curriculum developers, and policymakers committed to improving literacy opportunities for young learners. According to Donald Compton, Director Emeritus of FCRR and leader of the research, “English is a particularly hard language to learn. Some words are simply harder for children to learn to read than others, but we don’t have a complete understanding of all the factors that contribute to this.” This new resource aims to fill that gap.
Comprehensive Resource for Educators
The d-ELP database features continuous Item Response Theory (IRT)-based estimates of word reading difficulty, along with various accompanying word characteristics and extensive raw trial-level data. This allows teachers and caregivers to access lists of words with similar attributes, such as vowel combinations or sound blends, which they can use to create spelling lists or other instructional materials.
Data for the project were collected from 1,907 children across multiple sites in the U.S. Each child read lists of 250 to 500 words tailored to their reading proficiency. These lists included a diverse range of word difficulties, focusing on words appropriate for each child’s reading level.
Addressing Literacy Challenges
Learning to read in English presents unique challenges due to the language’s complex orthography and varied spelling patterns. Some words, such as “suede” and “yacht,” can be particularly difficult for young readers, even with well-developed decoding strategies. Until now, educators and researchers have lacked a comprehensive resource to understand the factors contributing to word reading difficulty in children.
The d-ELP database serves as a searchable, data-driven tool for exploring word-level reading challenges. By providing detailed information about word difficulty, the resource enables teachers to better target their instruction to each child’s developmental level. This targeted approach can support sequenced instruction on word difficulty, lead to greater generalization of word reading and decoding skills, and enhance understanding of student needs.
Accessing the Database
The d-ELP database is now available for public, noncommercial use. Users can easily search for word difficulty ratings and associated statistics through an intuitive online search engine. For more information and to register, interested parties can visit the d-ELP website.
This initiative from the Florida Center for Reading Research represents a significant step forward in addressing the literacy needs of children and enhancing educational outcomes in reading.
