Unforeseen Ripples of Text Complexity and CCSS


The Endpoint of the Staircase of Text Complexity: Revisiting Text Complexity at the Secondary Level: John Strong, SUNY-Buffalo & Elfrieda H. Hiebert, TextProject

CCSS authors argued that high-school students were unprepared to read the complex texts of college and careers, basing their conclusions on Williamson’s (2008) computation of the average Lexile (L) levels for 75 11th- and 12th-grade content-area textbooks. The average of these 75 texts, at 1123L, was 259L lower than college texts and 125L lower than workplace texts. This difference drove the accelerated staircase of text complexity (based on Lexiles) from K through Grade 12. Our study asks whether text complexity across distinctly different content areas can be treated as a monolith based on Lexiles, especially in relation to vocabulary.

To address the nature of complexity in different content-area textbooks, we examined two databases. The first was Bormuth’s (1969) database, which systematically analyzed texts from nine content areas. The second dataset consisted of texts from the middle unit of the median textbook in the Williamson analysis for four content areas: chemistry, mathematics, literature, and history. Main text and sidenotes were separated and analyzed separately according to: (a) Lexiles and components (sentence length, word frequency), (b) word frequency (e.g., frequent, very rare), and (c) word types (e.g., proper names, academic words).

Results of the first analysis indicated a significant difference between content-area texts for word frequency but not sentence length or Lexile. The average frequency of words was higher in literature texts than in chemistry and social studies but not mathematics texts. Results of the second analysis indicate that the rare words in the four content areas vary in their percentages but that the rare word types are distinct across content areas.

The use of a single metric such as Lexiles to describe all high-school texts across all content areas fails to acknowledge the significant variation across content areas and within textbooks. We conclude that Williamson’s study was inadequate by not accounting for differences between content areas and measuring the complexity of textbooks across sections.

Effects of Altered Lexile Levels of the Same Text on Reading Comprehension: Catherine L. Rand, Rutgers University

Following the mandates of the CCSS, the Lexile Framework for Reading is widely used to establish the complexity of texts. Recently, Lexile’s formula has been used to not only measure the complexity of a text, but to create simplified versions of informational articles at different levels. In theory, this simplification allows for differences in reading ability. But when simplification is based on quantitative measures, students’ comprehension may not improve. This study examined how simplified versions of a text affect reading comprehension.

All 335 students from grades 4-8 at three proficiency levels read one of five versions of an informational text retrieved from Newsela and then took a comprehension test. Results from a 3- way ANOVA showed no significant interaction between grade, reading level, and text condition. Pairwise comparisons showed that below-level readers’ scores were lower than the scores of on-level or above-level readers only when given extremely lower levels of texts. Regression analysis showed no significant contribution of text level to overall comprehension scores. Additionally, analyses showed that different types of comprehension were affected differently by simplifying the text. For example, questions requiring reasoning and evidence resulted in lower comprehension levels with simplified text.

Does One Size Fit All?  Exploring the Contribution of Text Features, Content, and Grade of Use on Comprehension: Heidi Anne Mesmer, Virginia Tech

Heidi Anne Mesmer will consider the findings in relation to a recent study which she has authored and which has not previously been presented at LRA: Does One Size Fit All? Exploring the Contribution of Text Features, Content, and Grade of Use on Comprehension (in press, Reading Psychology). Results of this study indicated that texts did having differing levels of various word features along both grade and content lines, especially in the area of sentence length. In addition, content and grade moderated the relationship between sentence length and comprehension.

Science is built on replications and elaborations of existing research. The two studies in this session add to a growing body of work that indicates that basing evaluations on sentence length, the dominant variable in the Lexile Framework, fails to capture the complexity of texts for students. In particular, as the ideas of texts become more complex in content areas, attention needs to be focused on the demands of new vocabulary, not simply the length of sentences.

The Science of Reading: Teacher Preparation, Research, and Policy



This symposium directly addresses our conference theme of “All of us are smarter than each of us: Collaborate for impact” by bringing together expertise on a topic that many LRA members are confronting: the science of reading.

Learning and instruction based on research evidence has been at the heart of LRA since its inception, as illustrated by the involvement of members in Becoming a Nation of Readers and the National Reading Panel’s (NRP’s) report. The current use of the term “science of reading,” however, has frequently been restricted to the first two of the five pillars identified by the NRP: phonemic awareness and phonics. This session consists of the responses to the science of reading discussion of three LRA members in their roles as teacher educator, researcher, and policymaker.

Preparing Teachers in Evidence-Based Instruction: Holly Lane, University of Florida

Hanford (2018) has suggested that many faculty in education either don't know the science or dismiss it. The program led by Holly Lane over an extended period of time demonstrates how teacher candidates can have a deep understanding of the whys and hows of evidence-based reading instruction and intervention.

In this program, teacher preparation is centered around an evidence-based intervention. In the first semester, teacher candidates tutor a struggling reader for 20 or more sessions after considerable practice in delivering the intervention. In the next semester, they use the same instructional routine with a small group of challenged readers. Finally, teacher candidates work with students who have significant reading disabilities.

The results of this teacher education program indicate that, with evidence-based knowledge and skills, teacher candidates can be part of effective interventions and have a solid foundation on which to build effective classroom practice.

The science of reading is often conveyed as if the conclusions from science about reading instruction are complete and unequivocal. In any science, especially one related to the complex process of reading, however, the questions of researchers evolve.

A blog and video series at TextProject will be available on December 1, 2020 where additional information can be accessed on five topics. Here is a brief overview of the topics:

  • Why orthography matters: English has a complex orthography that requires careful design and implementation of interventions.
  • What we know works in--Curriculum: Numerous reports and meta-analyses are unequivocal in describing the need for beginning readers to become automatic in recognizing consistent and prominent grapheme-phoneme correspondences (GPCs).
  • What we know works in--Instruction: One of many research findings is that reading acquisition is supported when the GPCs taught in lessons appear in the texts of application and practice.
  • What we know doesn’t work: Evidence also shows that some common practices such as teaching children to focus on pictures for clues in decoding do not support proficient word recognition.
  • What we don’t know… yet: Finally, numerous aspects of beginning reading instruction have yet to be addressed, such as the number of relatively unusual and rare vowel GPCs that need to be directly taught.

Bringing Evidence to Bear in State-Wide Policies and Practices: Caitlin Dooley, Deputy Superintendent, Georgia Department of Education

As deputy superintendent for a large state, Caitlin is responsible for responses about the science of reading to parent and citizen groups, educators, and state legislators. Three perspectives underlie the message that she and her colleagues have crafted.

First, the term “evidence-based” is used, as is the case in the Every Student Succeeds Act (U.S. Congress, 2015), rather than the more polarizing term of “science of reading.”

Second, just as the challenges confronting educators are broad, so too are the literatures that inform solutions. Literacy research encompasses topics such as social awareness, engagement and interest, and language development.

The final perspective is featured explicitly in all communications to stakeholders. This message is that the goal of policy and practice is to provide equitable learning opportunities for all students.

Discussant: Timothy Shanahan, University of Illinois-Chicago

Tim has had prominence in each of the three roles of teacher/teacher educator, researcher and policymaker. Recently, he published a foundational paper in the RRQ special issue on the science of reading. As indicated by the title of this article, "What constitutes a science of reading instruction?", Tim has cast the net to include instructional features in discussions of evidence-based reading instruction.

We are confident that the sharing of expertise that will occur in this session can support LRA members, whatever their role in the educational enterprise, in responding to the science of reading discussion in their institutions and communities.
