This experimental/comparison study of secondary-level, small-group instruction included 318 first- and second-grade students (170 ELL and 148 English-only) from six elementary schools. All schools served high numbers of ELL students with varying school SES in urban and suburban communities. Experimental schools implemented a three-tier model of intervention. In addition to primary-tier reading instruction, the second-tier, small-group experimental interventions included use of (a) evidence-based direct instruction reading curricula that explicitly targeted skills such as phonological/phonemic awareness, letter-sound recognition, alphabetic decoding, fluency building and comprehension skills; and (b) small groups of 3 to 6 students. Students at comparison schools were not exposed to a three-tier reading program but received (a) an ESL intervention using balanced literacy instruction with a focus on word study, group and individual story reading, and writing activities; and (b) small groups of 6 to 15 students. The ESL/balanced literacy intervention was generally in addition to primary reading instruction. Results indicated generally higher gains for ELL students enrolled in direct instruction interventions. Implications for research and practice are discussed.

We conducted a study designed to assess implementation of the classwide peer tutoring program and the relationship between implementation variation and student outcome. A clinical replication design was used. Five volunteer elementary teachers were trained to implement the program; their implementation was monitored for 19 consecutive weeks during 1 school year. Overall, the results indicated that specific variations in program implementation were associated with students' responses to treatment. It was also demonstrated that different teachers' applications of the program produced differential levels of student outcome. Implementation factors related to lower spelling achievement were (a) reduced opportunities to receive program sessions, (b) reduced probabilities of students' participation in program opportunities, (c) too many students assigned unchallenging spelling words, and (d) reduced rates of daily point earning reflecting lower levels of spelling practice during tutoring sessions. The implications of these findings and methods of preventing these implementation problems are discussed in the context of quality assurance and social validity.

For the past 18 years, we have engaged in a program of research designed to improve the literacy of poor culturally and linguistically diverse students and English language learners (ELL) in urban elementary schools. Intervention research has addressed the issue of what works best, how it can be applied and sustained schoolwide, and how computer and information management technology can improve quality and reduce teachers' work loads. The net product of this research is the ClassWide Peer Tutoring Learning Management System (CWPT-LMS). In this article, we report on use of the CWPT-LMS in the literacy instruction of elementary-level ELL. Five ELL teachers and 117 students in a multiracial/multiethnic urban elementary school, including students with disabilities, participated in the study. Results indicated that ELL made considerable progress in mastering the curriculum over periods ranging from 15 to 21 weeks of school across teachers, teachers implemented CWPT to high standards of fidelity, students' and teachers' satisfaction with the CWPT program was high, and consultation improved program implementation and student outcomes of all but one classroom. Implications of these findings are discussed.

Application of Skinner's principles to socially significant human behavior had been well articulated by 1968 (Baer, Wolf, & Risley, 1968). Applications of these principles by Baer, Wolf, Risley, Hall, Hart, Christophersen, and their colleagues were in evidence as early as 1964 in the homes, schools, and clinics of inner-city Kansas City, Kansas, at the Juniper Gardens Housing Project. The work continues relatively uninterrupted, having contributed extensively to the literature of applied behavior analysis and the lives of community residents. This article describes the project and illustrates how applied behavioral research was initiated and extended, how the work addressed general concerns in psychology, and how it continues to address contemporary concerns within the community.
