Researchers tend to use oral- and silent-reading fluency measures interchangeably and to generalize research findings across reading modes, especially from oral to silent reading. In this study, we sought to examine if oral and silent word-reading fluency rely on the same cognitive-linguistic skills. Three hundred and forty-five Greek children (80…

Purpose: The development of health literacy skills is of paramount importance especially for students, as it is associated with their wellbeing and academic success. Assessing students' health literacy is necessary for its advancement. This study comes to fill the need for a valid multidimensional health literacy assessment instrument for…

Prior research has suggested that mathematics specific anxiety and self-efficacy are strong predictors of mathematics performance. The purpose of this study was to examine this relationship using two nationally representative samples of Greek students in 2003 and 2012. Findings indicated that both mathematics anxiety and mathematics self-efficacy…

The present study investigates the effect of three neo-Piagetian constructs, namely Formal Reasoning (FR), Field Dependence/Independence (FDI) and Divergence (DIV), as well as the effect of age and gender, on students' portrayed representations of the atomic structure, considering their degree of coherence. For this purpose students'…

The aim of this study is to investigate the predictive factors that predispose secondary school students' interest in studying STEM (Science, Technology, Engineering, and Mathematics) fields in higher education. For this purpose, an already existing questionnaire was used and modified properly, according to the Greek educational system. The survey…

This article presents a case study that examines the level of integration of mathematical knowledge in physics problem solving among first grade students of upper secondary school. We explore the ways in which two specific students utilize their knowledge and we attempt to identify the epistemological framings they refer to while solving a physics…

This work investigates the formation of particular student profiles based on of their ideas relating to basic characteristics of the atom. Participants were secondary students of 8th, 10th and 12th grades from Northern Greece (n = 421), with specific cohort characteristics e.g. age, grade and class curriculum, and individual differences, e.g.…

The current study aims to investigate students' representations of the atomic structure in a number of student cohorts with specific characteristics concerning age, grade, class curriculum and some individual differences, such as formal reasoning and field dependence/independence. Two specific task contexts, which were designed in accordance with…

In this study, students' understanding of chemical changes was investigated in relation to four individual differences, related to logical thinking, field dependence/independence, convergence and divergence thinking. The study took place in Greece with the participation of students (n = 374) from three grades (8th, 10th and 12th grades) of…

This paper provides evidence on the sources of differences in inequality in educational scores and their evolution over time in four European countries. Using Programme for International Student Assessment data from the 2000 and the 2006 waves, the paper shows that inequality decreased in Germany and Spain (two "decentralised" schooling…
