In order to have a better understanding of the nature of reading behavior, it is quite essential to scrutinize the underlying assumptions of the two competing theories: the componential approach and unitary hypothesis and see how this is reflected on testing the reading skills. As a result, the current study was aimed at broadening the existing…

Many research studies have shown that lower-secondary school students' scientific literacy depends on their understanding of corresponding scientific concepts. Therefore, it is of great significance to model and assess students' conceptual understanding in learning specific scientific concepts, because it can reflect and diagnose students'…

In this paper, we examine whether a student's language background and other demographic factors have any relationship to their performance on prose questions in math, which we define as questions with open-ended answers containing one or more complete sentences of English. Prose questions stand in contrast to non-prose questions, which are more…

The purpose of this mixed methods study was to determine the effects of a tutorial program on first-grade children's reading skills and their tutors' (also preservice teachers) knowledge of reading instruction.

This study explored the impact of "Argumentation-driven inquiry" (ADI) on primary school students' argumentation performance in a blended synchronous learning environment (BSLE). A total of 159 fifth-grade primary school students (79 from an urban school and 80 from a rural school) participated in this quasi-experimental study. Students…

Intended consequences of giving applicants the option to select which test scores to report include potentially reducing measurement error and inequity in applicants' prior test familiarity. Our first study determined whether score choice options resulted in unintended consequences for lower performing subgroups by detrimentally increasing score…
