Weaver, Andrew; Kieffer, Michael J. – Grantee Submission, 2022
This study examines differences in English language comprehension, reading fluency, and executive functions among Spanish-English bilinguals with reading difficulties. Reading difficulties examined included general reading difficulties, defined by low word reading and reading comprehension, and specific-reading comprehension difficulties, defined…

Weaver, Andrew; Kieffer, Michael J. – Reading & Writing Quarterly, 2022
This study examines differences in English language comprehension, reading fluency, and executive functions among Spanish-English bilinguals with reading difficulties. Reading difficulties examined included general reading difficulties, defined by low word reading and reading comprehension, and specific-reading comprehension difficulties, defined…

Kieffer, Michael J.; Parker, Caroline E. – Regional Educational Laboratory Northeast & Islands, 2016
With the rapid growth in the number of English learner students served by schools in the United States, educators are increasingly concerned with how these students progress toward proficiency in English. The large and diverse English learner student population in New York City public schools, where more than 41 percent of students speak a…

Kieffer, Michael J.; Parker, Caroline E. – Regional Educational Laboratory Northeast & Islands, 2017
This longitudinal study analyzes high school graduation outcomes of students who entered New York City public schools in grade 5 or 6 as English learner students. It extends the work of Kieffer and Parker (2016) by investigating the high school graduation rates and the types of diploma earned by the 1,734 students who entered New York City public…

Halpin, Peter F.; Kieffer, Michael J. – Educational Researcher, 2015
The authors outline the application of latent class analysis (LCA) to classroom observational instruments. LCA offers diagnostic information about teachers' instructional strengths and weaknesses, along with estimates of measurement error for individual teachers, while remaining relatively straightforward to implement and interpret. It is…

Kieffer, Michael J.; Petscher, Yaacov; Proctor, C. Patrick; Silverman, Rebecca D. – Scientific Studies of Reading, 2016
Language comprehension is crucial to reading. However, theoretical models and recent research raise questions about what constitutes this multifaceted domain. We present two related studies examining the dimensionality of language comprehension and relations to reading comprehension in the upper elementary grades. Studies 1 (Grade 6; N = 148) and…

Kieffer, Michael J. – Journal of Learning Disabilities, 2014
This study investigated the role of morphological awareness weaknesses in the reading difficulties encountered by Spanish-speaking language minority learners and their native English-speaking peers in sixth grade. One hundred and thirty-eight students (82 language minority learners; 56 native English speakers) were assessed on English measures of…

Kieffer, Michael J.; Lesaux, Nonie K. – Reading and Writing: An Interdisciplinary Journal, 2012
Despite acknowledging the complex nature of vocabulary knowledge, researchers have rarely investigated the dimensionality of this construct empirically. This study was designed to test a multi-dimensional model of English vocabulary knowledge for sixth-grade students from linguistically diverse backgrounds (n = 584). Participants included language…

Kieffer, Michael J.; Box, Catherine DiFelice – Learning and Individual Differences, 2013
This study investigated the multiple roles of morphological awareness in reading comprehension for Spanish-speaking language minority (LM) learners and their native English-speaking (NE) peers. Sixth-grade students (N = 137; 82 LM, 55 NE) were assessed on English measures of derivational morphological awareness, morphologically complex academic…

Kieffer, Michael J. – Reading and Writing: An Interdisciplinary Journal, 2012
Using longitudinal data on a nationally representative U.S. cohort, this study investigated the relationship between socioeconomic status and students' reading growth between kindergarten and eighth grade. Piecewise latent growth modeling was used to describe nonlinear growth trajectories in reading during three developmental periods: kindergarten…

Kieffer, Michael J.; Biancarosa, Gina; Mancilla-Martinez, Jeannette – Applied Psycholinguistics, 2013
This study investigated the direct and indirect roles of morphological awareness reading comprehension for Spanish-speaking language minority learners reading in English. Multivariate path analysis was used to investigate the unique contribution of derivational morphological awareness to reading comprehension as well as its indirect contributions…

Kieffer, Michael J.; Lesaux, Nonie K. – Language Learning, 2012
This study tested three hypotheses about the direct and indirect contributions of derivational morphological awareness to English reading comprehension in sixth-grade students from differing language backgrounds (n= 952). Students included Spanish-speaking, Filipino-speaking, and Vietnamese-speaking language minority learners as well as native…

Kieffer, Michael J.; Lesaux, Nonie K. – Elementary School Journal, 2012
One dimension of language proficiency considered important for reading and writing academic texts is morphological awareness--the understanding of how complex words are formed from meaningful smaller units (i.e., affixes, roots) that contribute to words' meanings and functions. This quasi-experimental study evaluated the effects of instruction on…

Kieffer, Michael J.; Rivera, Mabel; Francis, David J. – Center on Instruction, 2012
This report presents results from a new quantitative synthesis of research on the effectiveness and validity of test accommodations for English language learners (ELLs) taking large-scale assessments. In 2006, the Center on Instruction published a review of the literature on test accommodations for ELLs titled "Practical Guidelines for the…
