The objective of this dissertation was to explore the paradoxical nature of Combinatorics as both a difficult and accessible domain in Mathematics, particularly for K-12 students. This paradox in Combinatorics' nature raised questions about how students interact with problems in this domain and the factors influencing their understanding and…

Background: Recent research on boredom suggests that it can emerge in situations characterized by over- and under-challenge. In learning contexts, this implies that high boredom may be experienced both by low- and high-achieving students. Aims: This research aimed to explore the existence and prevalence of boredom due to being over- and…

This paper seeks to better understand how unanticipated disruption influences teacher agency and professionalism. Drawing on a conceptual model of teacher agency the paper examines data from teacher focus groups conducted in one Australian K-12 school to understand the lived experience of teachers (n = 50) during an initial COVID-19 lockdown…

There is a large body of research exploring the difficulties young people experience on the transition to secondary education. However, there has been little comparative research yielding insights into how these experiences vary by institutional context. This article explores differences in school transition difficulties among young people in…

Large scale international assessments depend on invariance of measurement across countries. An important consideration when observing cross-national differential item functioning (DIF) is whether the DIF actually reflects a source of bias, or might instead be a methodological artifact reflecting item response theory (IRT) model misspecification.…

Teacher expectations and judgments about student capabilities are predictive of student achievement, yet such judgments may be influenced by salient dimensions of student identity and invite biases. Moreover, ambitious math teaching may also invite teacher biases due to the emphasis on student-generated inputs and ideas. In this pre-registered…

In this study, we present the newly developed "Misconceptions about Multimedia Learning Questionnaire" (MMLQ), we evaluate its psychometric properties (item difficulties, scale reliabilities, and internal structure), and we use it to examine the prevalence of four different misconceptions about multimedia learning in student teachers and…

The Advanced Placement program stands as the foremost source of college-level academics for millions of high school students in the United States and beyond. More than 22,000 schools now participate in it, across nearly forty subjects, from Latin and art to calculus and computer science. Yet remarkably little has been known about how this…

In this research, the effect of an item's type and cognitive level on its difficulty index was investigated. The data source of the study consisted of the responses of the 12535 students in the Turkey sample (6079 and 6456 students from eighth and fourth grade respectively) of TIMSS 2015. The responses were a total of 215 items at the eighth-grade…

This study focuses on education at primary and secondary level in Northern Ireland and questions whether it meets the needs of gifted students. Gifted students from Mensa were questioned about their experiences in school, and the majority of students stated that they did not have sufficient challenge in school, or any type of differentiation in…

Intro: In this survey the academic performance of primary and secondary school students in Greece, for three consecutive school years, was examined. The data concerned all Greek students of the last two grades of elementary school and the three grades of junior high school. Method: Unsupervised learning methods such as an X-means algorithm in…

This case study offers an organizational perspective on the ways in which a collective bargaining agreement shaped the administrative functioning of schools within an urban district. The data demonstrate how rational choice assumptions failed to account for the everyday site interactions between principals and teachers. Using complexity theory as…

We share ideas for preparing for and enacting high-cognitive demand tasks in ways that support students in articulating and justifying their ideas. We offer strategies for developing and posing several types of purposeful questions: (1) eliciting thinking, (2) generating ideas, (3) clarifying explanations, and (4) justifying claims.

Dynamic program visualization tools helps to reduce the cognitive load of students in learning programming. However, to authors' understanding there is no dynamic program visualization tool that can be used in a widely available smartphones. In this study, we design a Dynamic visualization engine for java programs that is integrated to java code…

The adoption of Common Core State Standards in the USA by 46 states and the District of Columbia has provided several new foci for K-12 instruction, not the least of which is the reading and understanding of complex text, a higher order thinking process. Closely associated with this is the notion of rigor, the focus of the present study. As…
