Responsive Reading Instruction
Study: Mathes et al. (2005)
Summary
Responsive Reading Instruction (RRI) was created to help the lowest-performing first and second graders learn to read competently and within the average range for their age groups. RRI small-group lessons are based on six elements that research has shown are important for effective instruction of struggling readers: 1. Instruction in Key Domains of Reading: RRI addresses the five key elements of effective reading instruction as noted by the National Reading Panel: phonemic awareness, phonics, fluency, vocabulary, and reading comprehension. 2. Explicit Instruction: RRI directly teaches the knowledge and skills involved in learning to read. RRI teachers provide explicit instruction by consistently using an instructional format designed to directly teach students what they need to learn. The teacher models, demonstrates, or clearly explains the concept or skill and guides the students as they practice it. 3. Opportunities to Practice: Students who are having difficulty learning to read need extended practice to master new knowledge and skills. RRI provides ample practice opportunities to enable students to practice skills and apply knowledge until it becomes a habit. 4. Targeted Instruction Based on Assessment: In RRI, teachers provide targeted instruction by assessing students strengths and needs to find out what they need to learn, providing instruction based on assessment results, monitoring student progress, and reinforcing/reteaching as needed. RRI teachers conduct assessments of one individual student in each lesson (on a rotating basis). Every student in the group is assessed at least once a week. 5. Scaffolding and Feedback: RRI provides teachers with effective scaffolding techniques to use when students struggle with a particular concept; for example, providing students books at the appropriate readability level, providing additional prompts, or breaking tasks into smaller steps. Immediate corrective feedback and specific praise is also employed to support students throughout the lessons. 6. The Home-School Connection: In RRI, the home-school connection is established early in the school year, as teachers connect with parents through notes and phone calls, as well as invitations to school to observe lessons or meet with the teacher. In addition, RRI teachers provide weekly updates to parents to summarize skills learned that week. RRI also provides strategies for teachers to recommend to parents for use at home. In the classroom, RRI teachers follow a consistent lesson structure that includes: Word Work, Print Concepts and Fluency, Assessment, Supported Reading, and Supported Writing. Optional DVD includes modeling of 34 of the RRI activities.

If possible, some form of ongoing support (such as coaching) is recommended.
Four days of training, along with a coaching protocol, were developed and field tested under funding from the US Department of Education through an IERI (Interagency Educational Research Initiative) grant (Scaling-up Effective Interventions for Preventing Reading Difficulties: Grant R305W030257; Patricia Mathes, PI). As part of that grant we provided train-the-trainer professional development for lead teachers who would train and coach other teachers in their school districts. This model has been subsequently implemented in other school districts.

Participants
- Describe how students were selected to participate in the study:
- During each of two years, we identified within these schools a sample of first graders who showed significant risk for reading difficulties. In order to determine which students were at risk for reading difficulty, classroom teachers and our research team screened all students at the end of kindergarten within the six participating schools using the kindergarten screening portion of the Texas Primary Reading Inventory (TPRI). At the beginning of the first-grade year we screened any students entering the school for the first time with the first-grade TPRI screen.
- Describe how students were identified as being at risk for academic failure (AI) or as having emotional or behavioral difficulties (BI):
- (A) students were screened with the TPRI at the end of Kindergarten or the beginning of 1st grade; (B) the Woodcock Johnson III Word Identification subtest (any student who could read ≥ 5 words was eliminated) and Observation Survey of Early Literacy Achievement text reading subtest (any student who could read Level D texts or higher with 90% accuracy was eliminated) was administered; (C) 1 minute, end-of-1st grade-leveled Oral Reading Fluency passage was administered (any student who was reading > 5 words was eliminated from the sample). This multiple part identification of at-risk students was also used in the second study included in this protocol, Effectiveness of a Supplemental Early Reading Intervention Scaled Up in Multiple Schools by Denton, et al. (2010).

For any substantively (e.g., effect size ≥ 0.25 for pretest or demographic differences) or statistically significant (e.g., p < 0.05) pretest differences between groups in the descriptions below, please describe the extent to which these differences are related to the impact of the treatment. For example, if analyses were conducted to determine that outcomes from this study are due to the intervention and not demographic characteristics, please describe the results of those analyses here.
Design
- What method was used to determine students' placement in treatment/control groups?
- Random
- Please describe the assignment method or the process for defining treatment/comparison groups.
- Once identified, all students designated as at risk within a school were randomly assigned to one of three conditions: enhanced classroom + Proactive Reading, enhanced classroom + Responsive Reading, or enhanced classroom only. In addition, we identified a sample of typically achieving readers by randomly selecting them from among all students in the same classrooms who evidenced no risk for reading problems. The purpose of this typically achieving group was to provide a benchmark of typical reading development in these classrooms.

- What were the background, experience, training, and ongoing support of the instructors or interventionists?
- Background and Experience: bachelors and masters degrees, teaching certifications in multiple areas, 2 of the 6 were certified reading specialists. Mean years of experience = 9 years, ranging from 3 to 22 years (includes teachers not under review). Training and Ongoing Support: 42 hours of professional development from the author of the intervention prior to instruction (Year 1) and an additional 12 hours in Year 2 of the study. Monthly half-day in-service meetings during the school year, onsite coaching. Although the vendor does not directly require or provide training for implementation of Responsive Reading Instruction, the program developer strongly recommends training. Training is available from the program developer in the form of a 2-day initial professional development prior to the provision of intervention with two one-day follow-up sessions to be provided later in the school year. Each of these days comprises about 6 hours of training. The developer also strongly recommends some form of ongoing coaching support for teachers who provide RRI.
- Describe when and how fidelity of treatment information was obtained.
- Classroom observations were conducted every 8 weeks, for a total of four observations for each participating teacher. A 3-point rating scale was used (3 = exact, 1 = poor). Prior to each wave of data collection, two or more observers established reliability by co-observing lessons, rating them independently, and comparing and discussing the ratings during a consensus meeting. Reliability was calculated by comparing the ratio of absolute agreements and disagreements. These co-observations continued until agreement between raters reached at least 85%. This was repeated at each wave of data collection (4 times each year).
- What were the results on the fidelity-of-treatment implementation measure?
- Having materials ready 96% of the time; having students seated 96% of the time, being warm and enthusiastic 100% of the time. They were rated as having appropriate pacing (mean = 2.5), following procedures for each section of the lesson routine (mean = 2.6), scaffolding student responses appropriately (mean = 2.7), and maintaining student attentiveness mean = 2.7.
- Was the fidelity measure also used in control classrooms?
- The control classrooms were observed to better understand the nature of instruction provided to students in this condition. The same measure of fidelity was not used. See page 156, Enhanced classroom instruction section.
Thirty teachers were observed 90 times. Observers reported the classroom was stimulating and motivating for 72.62% of the observations and that children were encouraged to express their ideas verbally in 90.27% of the observations. In terms of instructional content, instruction was provided in phonemic awareness during 34.65% of the observations, letter-sound correspondences in isolation during 72.72% of the observations, practice in reading words by sounding out during 82.36% of the observations, and decoding words using visual memory or context in 40.53% of the observations. Comprehension strategies instruction occurred in only 15.09% of the observations, vocabulary was presented in 83.75% of the observations, spelling was taught in 70.48% of the observations, and writing was included in 54.76% of the observations. While little comprehension instruction was provided, teachers frequently assessed students’ comprehension of text, asking literal questions in 83.53% of the observations and inferential questions in 61.60% of the observations.

- If you have excluded a variable or data that are reported in the study being submitted, explain the rationale for exclusion:
- Describe the analyses used to determine whether the intervention produced changes in student outcomes:
- Hierarchical Linear Modeling of both growth rate and end-of-year outcomes. Analyses took into account the shared variance within each student over repeated assessment times, and the shared variance from classrooms and schools inherent in the nested data structure. Analyses were able to effectively model individual student growth rates (slope estimates), and outcomes at the end of the year (intercepts). Finally, effect size estimates using HLM parameters are reported that compare the treatment and control group on growth rates and end of year outcomes. See pages 161-163 for further details on the analytical approach.
