Flattening the Developmental Staircase: Lexical Complexity Progression in Elementary Reading Texts Across Six Decades
November 20, 2025
This study examined lexical complexity patterns in elementary reading textbooks across four pivotal decades (1957, 1974, 1995, 2014) to understand how educational reforms have influenced developmental progressions in reading materials. The study analyzed a corpus of 320,000 words from one continuously published core reading program across grades 1–4 for four copyrights. The corpus consisted of a 20,000-word sample for each grade and year, analyzed for type-token ratio, percentage of complex words, and percentage of single-appearing words. The findings challenge narratives of declining text complexity and reveal that contemporary elementary readers experience compressed developmental progressions with elevated starting points but minimal growth trajectories. The implications suggest the need for reconceptualizing text design to balance appropriate challenges with systematic scaffolding, particularly for students dependent on school-based literacy instruction.
Unpacking automaticity: Scaffolded texts and comprehension
May 29, 2025
In this review, Freddy Hiebert examines the standard intervention for secondary students lacking automaticity—repeated oral reading—and the limited evidence for its impact on silent reading comprehension. She then presents an alternative approach using texts where the core 2,500 most frequent word families in written language comprise the majority of content.
The Presence and Progression of Rare Vocabulary in Texts Across Elementary Grades and Between Genres: How Rare Words Increase the Challenge of Reading and What We Can Do About It
May 14, 2025
The authors examined a set of rare words from narrative and expository texts aimed at Grades 1, 3, and 5. The purpose of the study was to determine the proportions of rare words that occurred across grade levels and genres, as well as to examine the features of rare words that occurred in these elementary texts.
Text types and their relation to efficacy in beginning reading interventions: The effects of decodable and non-decodable texts in early reading instruction
April 24, 2025
Supporting early readers means not only selecting texts at an appropriate level but also selecting texts of the appropriate text type. While necessary, decodable texts may not be sufficient for the full development of reading skills. Texts without phonetic control—non-decodable texts—may also provide a benefit.
Making sure the books check every box: Preservice teachers learning to select texts for reading instruction
April 2, 2025
To be prepared to teach reading, teachers must learn what makes a text complex: how text features contribute to text complexity. They must also learn how to locate and select appropriate texts for various pedagogies and know how to differentiate based on individual readers’ needs and interests.
