Models are central to the practice and teaching of science. Yet people often fail to grasp how scientific models explain their observations of the world. Realizing the explanatory power of a model may require aligning its relational structure to that of the observable phenomena. The present research tested whether "relational…

"MyTeachingPartner--Math/Science" ("MTP-MS") is a system of two curricula (math and science) plus teacher supports designed to improve the quality of instructional interactions in pre-kindergarten classrooms and to scaffold children's development in mathematics and science. The program includes year-long curricula in these…

This study examined the impact of independent practice of multiple-criteria text that targeted high-frequency words, decodability, and meaningfulness. Second-grade students, including at-risk students, were randomly assigned within classroom to a treatment group that read multiple-criteria text ("n" = 34), or contrast group that read…

Collaborative Strategic Reading (CSR) is a set of instructional strategies designed to improve the reading comprehension of students with diverse abilities (Klingner and Vaughn 1996). Teachers implement CSR at the classroom level using scaffolded instruction to guide students in the independent use of four comprehension strategies; students apply…

The purpose of this study was to design, implement, and evaluate the efficacy of scaffolded silent reading (ScSR) compared with the evidence-based practice of guided repeated oral reading (GROR) with feedback on 3rd-grade students' fluency and comprehension growth. Using a mixed-model dominant-less dominant design, the authors collected both…

This study examined effects of a repeated reading intervention, Quick Reads, with incidental word-level scaffolding instruction. Second- and third-grade students with passage-reading fluency performance between the 10th and 60th percentiles were randomly assigned to dyads, which were in turn randomly assigned to treatment (paired tutoring, n = 82)…

Students in fourth and seventh grade who were poor comprehenders were taught prediction, clarification, question generation, and summarization using scaffolding instruction. Performance on a standardized comprehension test improved for the students who received the instruction. (PCB)

Two studies--one quasi-experimental and one randomized experiment--were designed to evaluate the effectiveness of supplemental instruction in structural analysis and oral reading practice for second- and third-grade students with below-average word reading skills. Individual instruction was provided by trained paraeducators in single- and…

Two experiments involving 90 primary and intermediate-grade students studied how the COPPERS computer-based mathematical learning environment advances children's understanding that multiplication problems have many different correct solutions. Factors affecting learning and theoretical implications are discussed in terms of scaffolding learning.…
