This randomized control study compares the efficacy of two response-to-intervention (RTI) models: (1) Dynamic RTI, which immediately refers grade 1 students with the weakest skills to the most intensive intervention supports (Tier 2 or Tier 3); and (2) Typical RTI, which starts all students in Tier 1 and after 8 weeks, decides whether students who…

Direct linkWagner, Richard K.; Compton, Donald L. – Journal of Learning Disabilities, 2011
Dynamic assessment refers to assessment that combines elements of instruction for the purpose of learning something about an individual that cannot be learned as easily or at all from conventional assessment. The origins of dynamic assessment can be traced to Thorndike (1924), Rey (1934), and Vygotsky (1962), who shared three basic assumptions.…

Guan, Connie Qun; Ye, Feifei; Wagner, Richard K.; Meng, Wanjin – Reading and Writing: An Interdisciplinary Journal, 2013
The goal of the present study was to examine the generalizability of a model of the underlying dimensions of written composition across writing systems (Chinese Mandarin vs. English) and level of writing skill. A five-factor model of writing originally developed from analyses of 1st and 4th grade English writing samples was applied to Chinese…

Al Otaiba, Stephanie; Connor, Carol M.; Folsom, Jessica S.; Wanzek, Jeanne; Greulich, Luana; Schatschneider, Christopher; Wagner, Richard K. – Exceptional Children, 2014
This randomized controlled experiment compared the efficacy of two response-to-intervention (RTI) models--typical RTI and dynamic RTI--and included 34 first-grade classrooms (n = 522 students) across 10 socioeconomically and culturally diverse schools. Typical RTI was designed to follow the two-stage RTI decision rules that wait to assess response…

Wagner, Richard K.; Puranik, Cynthia S.; Foorman, Barbara; Foster, Elizabeth; Wilson, Laura Gehron; Tschinkel, Erika; Kantor, Patricia Thatcher – Reading and Writing: An Interdisciplinary Journal, 2011
Alternative models of the structure of individual and developmental differences of written composition and handwriting fluency were tested using confirmatory factor analysis of writing samples provided by first- and fourth-grade students. For both groups, a five-factor model provided the best fit to the data. Four of the factors represented…

Peer reviewedWagner, Richard K.; And Others – Journal of Educational Psychology, 1993
In a cross-sectional study of 95 kindergartners and 89 second graders, confirmatory factor analysis of a battery of phonological and control tasks was used to compare models of young readers' phonological processing abilities. Results suggest that phonological abilities are best conceptualized as relatively stable and coherent individual…
