Research Questions
1. Are there differences in student comprehension and vocabulary outcomes?
2. Are Read Aloud practices different across conditions?
3. Are Read Aloud practices associated with student comprehension and vocabulary outcomes?
4. Is fidelity of implementation associated with outcomes?
5. What is the impact of the Read Aloud intervention for students with low vocabulary and language skills?

Read Aloud Curriculum
• 9 science-based thematic units– 19 week implementation (including introductory pre-
unit)– 2 weeks/unit– 2 related books/unit
• 1 narrative, 1 expository
• 6 or 7 30-minute lessons per unit– 3 on the expository book– 3 or 4 on the narrative book
![Page 9: 1 Promoting Vocabulary Development and Knowledge of Narrative and Expository Texts Through Instructional Read Alouds in First Grade Classrooms: Results.](https://reader030.fdocuments.in/reader030/viewer/2022032523/56649d835503460f94a68ff4/html5/thumbnails/9.jpg)

Before• Identifying the purpose for reading
– Information or Storybook
• Previewing– Title, author, illustrator
• Predicting/Priming• Defining Critical Vocabulary (e.g. if
vocabulary word is part of book title)
![Page 10: 1 Promoting Vocabulary Development and Knowledge of Narrative and Expository Texts Through Instructional Read Alouds in First Grade Classrooms: Results.](https://reader030.fdocuments.in/reader030/viewer/2022032523/56649d835503460f94a68ff4/html5/thumbnails/10.jpg)
10
During• Using consistent framework (e.g., story
elements, info. headings, info. text focus questions)
• Question-asking strategies• Making connections (Text to text, text to self,
text to world)• Making inferences• Self-monitoring: What do you do when you don’t
understand something?• Vocabulary

Information Text Framework• KWL:
• What do we think we know about the topic?• What do we want to know about the topic?
• General Animal Focus Questions–What is a mammal? (What makes a
mammal a mammal?)–What are some types of mammals?
• Specific Animal Focus Questions–What does it look like?–What does it eat?
• What have we learned about the topic?

Research to Practice
–Apply the organizing frameworks to your content area units and themes.
–Does your content area instruction cover any other topics that don’t “fit” the organizing frameworks discussed? If so, what focus questions would apply?
![Page 20: 1 Promoting Vocabulary Development and Knowledge of Narrative and Expository Texts Through Instructional Read Alouds in First Grade Classrooms: Results.](https://reader030.fdocuments.in/reader030/viewer/2022032523/56649d835503460f94a68ff4/html5/thumbnails/20.jpg)
20
Research to Practice
–What books and themes will you use for your Read Aloud time?
–How will you integrate the purposeful use of narrative and informational text?
![Page 21: 1 Promoting Vocabulary Development and Knowledge of Narrative and Expository Texts Through Instructional Read Alouds in First Grade Classrooms: Results.](https://reader030.fdocuments.in/reader030/viewer/2022032523/56649d835503460f94a68ff4/html5/thumbnails/21.jpg)
21
Research to Practice
– Think strategically about before and after reading components.
– Connect a text-structure framework throughout the before, during, and after reading components.
– Emphasize vocabulary through explicit instructional routines and opportunities to interact deeply with target vocabulary.
– Systematically review and summarize.
![Page 22: 1 Promoting Vocabulary Development and Knowledge of Narrative and Expository Texts Through Instructional Read Alouds in First Grade Classrooms: Results.](https://reader030.fdocuments.in/reader030/viewer/2022032523/56649d835503460f94a68ff4/html5/thumbnails/22.jpg)
22
Research to Practice– Practice retelling!– Promote active student engagement and
talk.• Active student responding (e.g.,
thumbs-up, thumbs-down)• Student partner talk (e.g., “Book Clubs”)• Student group and individual responses• Follow-up “Talk Routines”

Measures
• Comprehension– Narrative Retell (Strong Narrative Assessment
Procedure, SNAP, Strong, 1998)– Information Retell– Gates-MacGinitie Listening Comprehension Subtest
• Vocabulary– Depth of Vocabulary Knowledge (Target Vocabulary
from Read Aloud Curriculum)
• Language– Test of Oral Language Development-Primary: Third
Addition (Newcomer & Hammill, 1997)
![Page 25: 1 Promoting Vocabulary Development and Knowledge of Narrative and Expository Texts Through Instructional Read Alouds in First Grade Classrooms: Results.](https://reader030.fdocuments.in/reader030/viewer/2022032523/56649d835503460f94a68ff4/html5/thumbnails/25.jpg)

Statistical ModelA two-level hierarchical linear random intercept model was used for the analysis of intervention effect on each assessment. Intervention effects were examined at the classroom level, while students’ language/literacy risk status and pretest scores were controlled as student-level predictors and covariates.
Level 1 (student)
Yij = β0j + β1j (pretest*) + β2j (at-risk language) + β3j (at-risk
literacy) + β4 (at-risk in both) + rij
*Pretest scores were grand mean centered.
Level 2 (classroom)
β0j = γ00 + γ01 (intervention) + u0j
β1j= γ10
β2j= γ20
β3j= γ30
β4j= γ40

Process Hypotheses: Mediating and Dose-Response
Effects• Process analyses will allow us to test:
– (a) hypothesized mediating effects (Baron and Kenny,1986).• H1: Teachers in treatment classroom will engage in
more dialogic discussion with children than in control classrooms.
• H2: Teachers in treatment classrooms will provide more opportunities for students to respond to questions and engage in text talk than in control classrooms.
• H3: Students in treatment classrooms will be more engaged than students in control classrooms.
![Page 31: 1 Promoting Vocabulary Development and Knowledge of Narrative and Expository Texts Through Instructional Read Alouds in First Grade Classrooms: Results.](https://reader030.fdocuments.in/reader030/viewer/2022032523/56649d835503460f94a68ff4/html5/thumbnails/31.jpg)
31
Process Hypotheses: Mediating and Dose-Response
Effects• Process analyses will allow us to test:
– (b) the degree to which implementation differs across treatment classrooms is associated with differences in children's vocabulary and retell outcomes.• H4: Differences in implementation fidelity will be
related to student outcomes.

32
Mediation Observation System
• Measures of read aloud instruction before and after intervention training in experimental and comparison conditions.
– Two observations before and after intervention1. Each teacher reads the same narrative book
2. Each teacher reads the same expository book
– Twelve first-grade teachers: 6 intervention and 6 comparison
![Page 33: 1 Promoting Vocabulary Development and Knowledge of Narrative and Expository Texts Through Instructional Read Alouds in First Grade Classrooms: Results.](https://reader030.fdocuments.in/reader030/viewer/2022032523/56649d835503460f94a68ff4/html5/thumbnails/33.jpg)
33
Mediation Observation System
• Observation protocols correspond to three sections of read aloud lessons:
1. Before text reading
2. During text reading
3. After text reading
![Page 34: 1 Promoting Vocabulary Development and Knowledge of Narrative and Expository Texts Through Instructional Read Alouds in First Grade Classrooms: Results.](https://reader030.fdocuments.in/reader030/viewer/2022032523/56649d835503460f94a68ff4/html5/thumbnails/34.jpg)
34
Description of Observation System
• Observations divided into three sections to correspond to distinct parts of read aloud lessons:
1. Before reading the text,2. During the reading of the text, and3. After reading the text
• Each section contained items addressing components associated specifically with read aloud time (e.g., teacher sets purpose for reading), and generic instructional components (e.g., teacher asks questions).
• Two observations: one tailored to reading narrative texts, and one tailored to reading expository texts.

Treatment Fidelity Observations
• The six teachers in the experimental condition were observed implementing all three narrative lessons of a complete instructional unit.
• Fidelity observations were highly specific, and included items suggested but not required in the intervention.

Conclusions
• Incorporating more strategic vocabulary and comprehension instruction during read alouds appears to be a promising way to boost student vocabulary and comprehension.
• Next Steps:– Examine impact of Booster instruction on
vocabulary and comprehension achievement of students with low vocabulary and language skills.

Research to Practice:Conclusions
• Think thematically and pair information and narrative books.
• Consider instructional supports for students with low vocabulary and language skills.

Research to Practice:Conclusions
• Plan read alouds more strategically!– How will you use a repeated reading model? How can you read
books differently for different comprehension purposes?– What text-to-text, text-to-self, text-to-world links will you use?– What comprehension frameworks will you use?
• How will these frameworks be used before, during, and after (retells!) reading?
– What vocabulary words will you select?• What vocabulary routines will you use? How will you use
questions, reasons, and examples to promote depth?– How will you expand discourse and facilitate talk during read
alouds?• What ways can you increase your use of partner talk?
