What Is So Disturbing?
• In 2011, 68% of fourth-grade students and 62% of
eighth-grade students with disabilities scored below
basic on NAEP Reading.
• In 2011, 29% of fourth-grade students and 20% of
eighth-grade students without disabilities scored
below basic on NAEP Reading.
• From 2009 to 2011, reading results for students with
disabilities declined.
Synthesis of Intensive Interventions:
Grades 4 Through 12
• More than 75 sessions
• No studies for grades 10–12
• 11 experimental or quasi-experimental studies for
secondary, 19 for elementary

Why Larger Effects in Elementary?
It may be that the interventions are not less
effective but that we have fewer false positives
than with secondary students.
OR…
It may be that older students have more
intractable reading problems.

Years 1 and 2: A Summary
Tier I Intervention
All students in both treatment and comparison conditions
received enhanced Tier I treatment:
• Comprehension instruction within content areas
• Academic vocabulary within content areas
• Text as a source of evidence

(2010). The relative effects of group size on reading progress of older students with reading
difficulties. Reading and Writing: An Interdisciplinary Journal 23(8), 931–956.
Year 1 Findings
Year 1 addressed two primary questions:
1. Overall, how effective was the treatment in
enhancing students’ outcomes in reading?
2. Do students who are assigned to small-group
instruction outperform students in large-group
instruction?
Question 1: Efficacy of Tier II
Tier II treatment in addition to the enhanced classroom
instruction (Tier I) was associated with gains in decoding,
reading fluency, and comprehension (d = 0.16) over
students with reading difficulties who received from the
research team only the enhanced classroom instruction
(Tier I)—although many of the Tier I-only students also
received interventions from their schools.
Question 2: Effects of Group Size
• Both treatment groups outperformed comparison.
• There were no between-group treatment differences.
What Happened to High vs. Low
Responders?
• Students who met threshold: No more treatment
• Students who did not meet threshold: Additional
intervention in Year 2
Year 2 Research Question
Do students with significant reading disabilities (low
response to previous year treatment) make significantly
better gains in standardized versus individualized
treatments?

Efficacy of RTI for T vs. C Students
• What is the efficacy of a 3-year, response-based, tiered
model for allocating reading interventions across sixth
through eighth grades?
• Does the 3-year, response-based, tiered model for
struggling readers close the gap with typically achieving
peers?

in middle school. Reading Research Quarterly.
Results
• Data multivariate normal
• 3-year trajectories fit for the originally sampled group
(T and C)
Treatment outperformed comparison (ES = 0.26).
• Based on a multi-indicator, multilevel model
• Based on a rather robust comparison condition
Results
• Considering slope over time
• Treated students outperformed typical readers

Impact of Treatment on Attention
Using the same 3-year sample of students, we examined
effects for teacher ratings of attention:
1. Does reading intervention affect behavioral
attention?
2. What is the causal sequence of the effect of
intervention?

of a longitudinal intervention for reading on level of attention in middle school

• Reading treatment had a direct effect on reading ability,
and reading ability over time predicted behavioral attention.
• Finding: Improved reading (causal order) to improved attention

Note. Values are latent estimates of average reading. Time 1 in Tier I attention fixed at 0. All other
estimates (across time within Tier I and for all time points in Tier II) are relative to that baseline.
What Is Special About
Special Education Instruction?
Effects are stronger if interventions do the following:
• Use explicit instruction
• Increase time on task
• Provide opportunities to respond with feedback
• Reduce size of instructional groups
• Are comprehensive (multicomponent) and include a
self-regulation component
• Differentiate according to instructional needs
• Teach in the context of academic content
Sample Inference Instruction
Follow along as the teacher reads this paragraph. Try to picture the
scene in your head. Where does it take place? Who is talking?
"Immigrant families were crowded everywhere, along with boxes and barrels of supplies.
Everything smelled badly. Everywhere you turned, you bumped into someone or fell over a bundle.
It was pure havoc. One or another of the boys was bawling most of the time, especially George. It
took a lot of impatience for me to hit a child, but one night I had had it. In anger, I got up, struck a
match, and lit the kerosene lamp on the wall. My eyes focused on the ceiling quite accidentally and
I saw a mass of crawlers squirming and creeping into crevices. I examined George's body and found
bedbugs crawling about, his body covered with red blotches, and then I knew why he was crying…"

All around the world, fall is a time to
harvest. It is the result of many months of
work. In spring before anything is planted,
the fields are bare. Farmers plant their
seeds. As the little plants grow, the farmers
care for them. They water them during the
sweltering heat of summer. They pull
weeds and protect the plants from bugs.

Jamestown: The First English
Colony in America
Explorers had been landing in
America for some time before
English settlers arrived in what is
now Jamestown, Virginia, in 1607.
But it was in that spot on the James
River that English colonization
began and with it, the history of
America. James the First was king
of England at that time, and he had
granted approval for a group of
businesspeople to settle in this new
land. They were part of the Virginia
Company, and they got the goahead in 1606. By December of
that year, the expedition was ready.

procedure
1. Explorers had been landing in America for some time
before English settlers arrived in what is now
Jamestown, Virginia, in 1607. But it was in that spot on
the James River that English colonization began and
with it, the history of America. James the First was king
of England at that time, and he had granted approval for
a group of businesspeople to settle in this new land. They
were part of the Virginia Company, and they got the goahead in 1606. By December of that year, the expedition
was ready.
Question: Tell me what this part of the story is about.
Possible answer: example: This was about some of the
first settlers who came from England and started to
colonize America in the early 1600’s.
Text-based Instructional Routine
Instructor provides appropriate scaffolds to restrict the
amount of text the student has to address in order to
find the answer. Instructors start with a section of text.
Example
How did the Native Americans help the Pilgrims?
No answer.
Look at the second paragraph to find out how the Native Americans helped the Pilgrims.
No Answer.
Look at the last sentence of the second paragraph to find out how the Native Americans helped
the Pilgrims.
No Answer.
In the last sentence, there is a key word: showed. It tells me the Native Americans showed the
Pilgrims something. What did the Native Americans show the Pilgrims?
They showed them how to grow enough food to last the whole year.
Correct.
The Native Americans helped the Pilgrims by showing them how to grow enough food to feed
themselves all year.
