AERA Emergent Reader Symposium, 2013

During the 2013 American Educational Research Association (AERA) Annual Meeting in San Francisco, California, a team of MetaMetrics® researchers along with colleagues from other institutions presented the results of a two-year emergent reader text-complexity study.

Here’s a summary of the research and the implications:

  • The research was achieved by having young students read texts and also by having teachers gauge the texts’ complexity.


  •  As a result of the emergent reader research, the Lexile® scale was enhanced; now any early-grades text can be placed on the Lexile text-complexity scale.


  • The enhanced Analyzer incorporates several text-complexity indicators, including word structure demand, word meaning demand, sentence-level characteristics, and cross-sentence features that model patterning and repetition found in many emergent texts.

What makes the Lexile scale so unique in the field is the degree to which it uses empirical data from students and educators in determining the text complexity of early grades. In comparison, most other text-complexity measures are derived solely from text analysis.

The study was completed by a team from MetaMetrics comprised of; Dr. Heather Koons, Director, Consulting and Development Services and The University of North Carolina Clinical Assistant Professor, Dr. Kim Bowen, Lexile Research Associate, Dr. Jill Fitzgerald, Distinguished Research Scientist and The University of North Carolina Emerita and Research Professor, Mr. Jeff Elmore, Research Engineer, Dr. Mary Ann Simpson, Sr. Psychometrician, Dr. Robin Baker, Director Analytical Services, Dr. Ellie E. Sanford-Moore, SVP Research and Development and Dr. A. Jackson Stenner, Chairman, CEO and Co-founder and The University of North Carolina Research Professor.

The team was joined by Dr. Elfrieda Hiebert, President and CEO of and Amy Clark, Graduate Research Assistant at Kansas University. Dr. P. David Pearson was a discussant at the AERA presentation.

The emergent reader work will be incorporated into the Lexile® Analyzer this fall.
