Research Findings: The present study investigates both the proximal processes and contextual influences on children's oral language development in preschool. We examine whether teacher language practices vary across activity settings and program type, which teacher language practices predict children's oral language skills, and potential…

This i3 scale-up study examined the implementation and effectiveness of a 3-year literacy intervention developed by the Children's Literacy Initiative (CLI). The study was a school-level cluster randomized controlled trial conducted in 55 elementary schools from four states. Implementation results showed a high level of fidelity of intervention…

The Association of American Medical Colleges has encouraged educators to investigate proper linkage of simulation experiences with medical curricula. The authors aimed to determine if student knowledge and satisfaction differ between participation in web-based and manikin simulations for learning shock physiology and treatment and to determine if…

This paper provides practical guidance for researchers who are designing and analyzing studies that randomize schools--which comprise three levels of clustering (students in classrooms in schools)--to measure intervention effects on student academic outcomes when information on the middle level (classrooms) is missing. This situation arises…

Although many programs remotely disseminate information to students about the college application process, there is little evidence as to how students experience these programs. This paper examines a large-scale remote counseling program in which college counselors initiated interactions with 15,000 high school seniors via text message to support…

We report the results of a preregistered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no 2 consecutive problems require the same…

There is continued debate about the changing and varied nature of first year college courses in American higher education institutions; therefore, additional research is needed to inform faculty and administration of the specific areas on which to focus for teaching and learning in these courses. This study is one possible approach to easily…

Many children fail to reach proficient levels in reading only because they do not receive the amount and type of instruction they need (Foorman, Francis, Fletcher, Schatschneider, & Mehta, 1998; Morrison, Bachman, & Connor, 2005 2005; Vellutino, Scanlon, Sipay, Small, Pratt, Chen, & Denckla, 1996). However, providing effective…
