….with many thanks to
Darrell Morris, Appalachian State University
Theoretical Frame: Readers
University of Virginia Intervention Fluency work: repeated readings Word study: systematic, explicit,
isolated Assisted reading on instructional level
4-5x per week; 45 minutes, 80 lessons
(Brown, Morris, & Fields, 2005; Invernizzi, Juel, & Rosemary, 2001; Morris, Shaw, & Perney, 1991; Santa & Hoien, 1995; Morris, Tyner, & Perney, 2003)
Theoretical Frame: Educators
University of Virginia P.D. Year-Long Clinical Practicum in schools
Modeling, Observation, Coaching (36 hours)
Tutoring (80 hours – minimum)
(Brown, Morris, & Fields, 2005; Morris, Shaw, & Perney, 1991; Morris, Tyner, & Perney, 2003)
Theoretical Frame: Group Size
University of Virginia Model 1:1 tutorial
Elbaum, Vaughn et al., meta-analysis 2002 No empirical evidence for 1:1
advantage over groups
Theoretical Frame: Group Size
Vaughn et al., (2003) G2 Group size: 1:1 vs. 1:3 – n.s.; 1:10 *
Brown, Fields, Craig & Morris (2008) G2&3 Group size: 1:1 vs. 1:3 – n.s.
Helf et al., (2009) G1 Group size: 1:1 vs. 1:3 – n.s.
Research Question: Readers
Does 1:1 intervention for at-risk 1st graders have an advantage over intervention delivered in a 1:4 group format?
Research Question: Educators
Can non-certified paraprofessionals deliver reading intervention as effectively as certified teachers in 1:1 and 1:4 formats…
…when supervised by a intervention specialist?
Methods: Readers
N = 214 14 Title 1 and non-Title 1 schools Public: rural & urban Grade 1 at-risk Diverse SES, ethnicity Randomly assigned to 1:1 or Quad
(1:4)
Methods: Educators
N = 47 (21 certified; 26 non-certified)
literacy coaches, paraprofessionals Each pre-certified in Early Steps Each tutored 1:1 and 1:4 Each was observed 13 times over
year
Methods: Intervention
45 minute Early Steps lesson 80 lessons over year’s time Identical content in text & word
study
Students in Quads worked chorally on same materials at same time during their lessons.
Methods: Pre-Post Measures
Criterion-referenced Word recognition automaticity (Flash) Reading Level Assessment – RLA

Discussion: Readers
Extends Vaughn et al., 2003 & Brown et al., 2008 to 1st graders
Extends Helf et al., 2009 to group of 4
No advantage for at-risk G1 students in 1:1 group format over 1:4 (Quads)
Discussion: Educators
Extends Brown, Morris & Fields (2005), Brown et al., (2008) paraprofessionals as effective as certified educators in delivering intervention. Note: ALL (non-cert & cert) were
trained & supervised by intervention specialists
Implications for Ed Practice
Growing evidence that small groups are effective means of delivering intervention to primary grade struggling readers.
more desirable than 1:1--stretches resources such that more students receive intervention (Title I schools)
Implications for Ed Practice
Trained, supervised paraprofessionals can effectively extend the reach of classroom teacher and literacy coaches.
Sheds new light on the assumption that “only the most highly qualified educators should be working with struggling readers.”
Implications for Ed Practice
>1 group size requires management skill on part of educator
When to Choose 1:1 group size Students who “don’t fit” a group Educators who “don’t fit” with
groups
Future Research
Economies of Scale - 1:1 vs. 1:5 or 1:6 advantage?
Intervention that targets earlier phases of development At-risk pre-alphabetic readers in early
K At-risk partial alphabetic readers in
mid K
