1) Kinds of Words: (a) Concreteness/ Familiarity
Know: concreteness makes a difference in word learning
From T.K. Landauer, K. Kireyev, & C. Panaccione (20090. A new yardstick and tool for personalized vocabulary building. Proceedings of the NAACL HLT Workshop on Innovative Use of NLP for Building Educational Applications, pp. 27‐33. Boulder, CO.
1) Kinds of Words: (a) Concreteness/ Familiarity
Know: concreteness makes a difference in word learning
Don’t know: Degree to which concreteness/familiarity is a factor in the beginning reading of children who learn primarily in the school setting. Particularly: When concreteness/familiarity is overshadowed by an emphasis on minimally different words in extreme decodables.

2) Type‐Token Ratio (TTR) Know: Beginners need to have high levels of success to persevere & learn (Brophy et al., 1979)
Don’t Know: Optimal levels of TTR at different phases in learning to read

Don’t Know: Optimal levels of TTR at different phases in learning to read
Probably Know: TTR of .15+ is too high for students in first of three early reading phases
3) Repetition Know: Repetition makes a difference in word learning

3) Repetition Know: Repetition makes a difference in word learning Don’t know: How much repetition is needed of words with different features as a function of proficiency
Probably know: Less than 5 repetitions of a word (especially if the word is not highly concrete and has a highly prolific rime) are not enough with students in phase 1 of three phases of learning to read
Word recognition is an aspect of vocabulary knowledge. Words always have orthographic‐phonological‐morphological features. They also vary considerably in the frequency with which they are used in oral and written language and in the degree to which they are familiar and represent concrete entities in children’s worlds.
In attempting to find the “winner” of the best word characteristic for teaching children to read, researchers have disregarded three critical variables:
The overall distribution of words that are highly frequent, decodable, and familiar/concrete in a beginning reading diet.
The ratio of unique words to total words in a beginning reading diet.
The repetition of words (with particular features and at particular points in students’ reading acquisition)
Local or linear text structure Within‐sentence/within‐paragraph or sentence‐to‐sentence/paragraph‐to‐paragraph
Ability to parse sentence syntax is an essential if lower‐level component of the text comprehension process (e.g., Graesser, Swamer, Baggett, & Sell, 1996)
There is near‐universal inclusion of a measure of sentence length in readability formulas (Klare, 1984), including those designed especially for use with primary‐grade text (e.g., Spache, 1953)
Is sentence length an adequate indicator of syntactic demands in primary‐grade text?
LRA, 2010 Mesmer, Hiebert, & Cunningham

Shortening sentences in a text often fails to make it easier and can make it harder (Davison & Kantor, 1982; Pearson, 1974)
Average sentence length can contribute to overestimating the difficulty of primary‐grade reading materials (Bormuth, 1985; Carver, 1985)
Average words per T‐unit is a statistically significant predictor of books’ Reading Recovery level, but average words per sentence is not (Cunningham, Spadorcia, Erickson, Koppenhaver, Sturm, & Yoder, 2005)
Yet, many books are leveled for K‐3 readers using systems that rely on average sentence length such as the Lexile Framework
Cohesive text is easier for readers in general to comprehend (Gernsbacher, 1990)
Comprehenders make use of referential cohesion to construct their macrostructure memory model for a text (Kintsch, 1998; Van Dijk & Kintsch, 1978)
Phonics‐Firsters generally say yes Whole‐Languagers generally say don’t worry about it Neither‐Ones generally say no, texts should get gradually harder simultaneously along multiple dimensions and we call for research to teach us how they can do it best

Other than the tradition of using average sentence length to predict a text’s syntactic complexity—a tradition we have good reason to question,
there is very little research to help us select or author text for K‐3 readers that would place appropriate syntactic and cohesion demands on them
Fortunately, there are a number of researchable questions, the answers to which could advance our knowledge of how the syntax and referential cohesion of primary‐grade text can facilitate reading development
Degree to which measurements in a study are actually capturing the constructs that they purport to measure
Study results rest on construct validity Can have predictive validity but no construct validity Can have face validity but no construct validity
Multiple measures to represent constructs Can be supported but not proven.
Why is it important?

• Theory‐driven research
• Well specified constructs
• Well‐matched measures to constructs

Lack of agreement on theory driving text Language, content, format? (Brooks, 1996; Fountas & Pinnell,
2006; 2002; 1999; Hart‐Hewins & Wells, 1999; Miller, 2000; Peterson, 2001; Syymusiak & Sibberson, 2001; Weaver, 2001)
Three‐cueing systems? Theory very complex
Language (sentence complexity, vocabulary, cohesion, familiarity , structure, predictability)
Content (story line, familiarity, genre)
Theory is too simple One piece puzzle. Letter/sound supports only
The constructs break down because they are measured in contrasting ways Regularity is measured in 5‐10 different ways.
Text features are operating that are not part of the theory Decodable text‐ repetition, pacing Leveled text‐# words/book
Two definitions: Words matched to theoretical lessons articulated in teachers’
manuals (e.g. Foorman, Francis, Davidson, Harm, & Griffin, 2004; Stein, Johnson, & Gutlohn, 1999)
Words matched to actual lessons students received (Mesmer, 2001; 2005; 2010; Jenkins, Peyton, Sanders, & Vadasy, 2004). T
Small groups of students in short term interventions (14 sessions) had more graphically‐similar error when reading highly decodable text (Mesmer, 2001; 2005).‐Opportunity?
One‐on‐one tutoring with phonics instruction in long term intervention no effects of text decodability (Jenkins et al. 2005).

Study Measure Finding
Juel & Roper‐Schneider (1985)
Three‐Tiered Rating Transfer (seat, bag, yell) Association (law, that) Irregular (come, pear)
Preprimer levels Decodable M= 1.2 Contr0l M=1.8
Mesmer (2005) Hiebert & Menon 8‐level system‐vowel complexity
Highly decodable text: ‐More cvc ‐Fewer silent e words ‐Fewer vowel digraphs; ‐‐‐‐Fewer diphthongs Also ‐more repetitions per word (4.4 vs. 3.1); ‐fewer syllables per word (.1. vs. 1.3).
Study Measure Finding
Compton et al. (2004) Menon & Hiebert Decodable words (all 8 levels) Non‐decodable ‐ multisyllabic ‐nondecodable monosyllabic words Also percentage of high frequency words ‐frequency, rather than decodability to predicted accuracy whereas ‐both high frequency and decodable words predicted fluency
The different operationalizations of LTTM and regularity impact the interpretations of findings and their potential applicability.
Study Globally‐State Generalization Unexamined Construct
Unpacking the Construct ‐Reinterpretation
Compton et al. (2005) Decodability supports fluency
Single‐syllable, high frequency words enhances reading rate.
Foorman et al. (2004) Some basals offer close to 70% decodability
If teachers follow teachers’ manuals exactly and children learned everything they are taught, basals would range from 15‐70% decodable (M =42%, across six basals)
Juel & Roper/Schneider, 1985
Decodability at the preprimer level supports better word recognition in the first two‐thirds of first grade
Word regularity at the preprimer level along with word repetition and number of syllables supports word recognition
Compton et al. (2004) Juel & Roper/Schneider (1985) Mesmer (2005)
The active ingredients inDluencing word recognition in highly decodable text are regularity and LTTM.
Active ingredients in highly decodable texts that inDluence word recognition include word frequency (Compton, et al. 2005; Hoffman et al., 2001) and word repetition (Juel & Roper/Schneider, 1985; Mesmer, 2005)
Mesmer (2001, 2005)
Readers use a letter/sound strategy more in a decodable text.
At initial stages of reading, a tightly controlled text provides more opportunities to decode but we don’t know if other formats, with the same number of opportunities would result in similar levels of decoding.

Ask, “Does the emperor have clothes? Is there construct validity here?” Face validity ≠ construct validity
Saying something matches a theory or construct does not make it so.
Predictive validity ≠ construct validity Shoe size predicts reading level
Studying text is complex Manipulating one text variable shifts others
Complex =entangled
It is incomplete to design texts with attention only at the word level (i.e. decodable) or only at the sentence‐level or only at the text level (i.e. leveled).
