Graphical literacy or graphicacy is a critical component of scientific literacy. Graphs are used to integrate and represent complex sets of information requiring abstraction from perceptual experience. They form essential parts of the Mathematics and Science curriculum across school curricular stages. A key to developing meaningful pedagogic…

Vertical scales are frequently developed using common item nonequivalent group linking. In this design, one can use upper-grade, lower-grade, or mixed-grade common items to estimate the linking constants that underlie the absolute measurement of growth. Using the Rasch model and a dataset from Curriculum Associates' i-Ready Diagnostic in math in…

Online one-on-one tutoring serves as a supplementary approach to traditional classroom instruction. It has been shown to enhance personalized learning and academic performance. However, the dynamics of dialogic interactions within this educational setting are not fully understood. Thus, we present a computational analysis of dialogic interactions…

Purpose: Graphotactic regularities are statistical regularities governing orthographic systems that children are sensitive to from the start of their literacy learning. The current study observed changes in children's sensitivity to a set of graphotactic patterns across different grades in elementary school and measured the contribution of skills…

Motivation plays a crucial role in mathematical competence, with motivated students tending to perform better than those who lack motivation. Given that teachers can play a significant role in fostering student motivation, the aim of this study was to investigate teachers' influence on students' motivation to learn mathematics. Alongside the…

We examined how often teachers' targeted interventions fail in stopping bullying and to what extent this varies between schools vs. between students involved. In addition, we investigated which student-level factors were associated with intervention failure. Data were collected annually in 2011-2016 via online questionnaires and included responses…
