Although the simple view of reading and other theories suggest that listening comprehension is an important determinant of reading comprehension, previous research on linguistic transfer has mainly focused on the role of first language (L1) decoding skills in second language (L2) reading. The present study tested the assumption that listening…

A model of expertise in physics was tested on a sample of 374 college students in 2 different level physics courses. Structural equation modeling was used to test hypothesized relationships among variables linked to expert performance in physics including strategy use, pictorial representation, categorization skills, and motivation, and these…

Response to intervention (RTI) models for identifying learning disabilities rely on the accurate identification of children who, without Tier 2 tutoring, would develop reading disability (RD). This study examined 2 questions concerning the use of 1st-grade data to predict future RD: (1) Does adding initial word identification fluency (WIF) and 5…
