Prior research demonstrates the importance of school climate in shaping student behavior but tells us less about which aspects of school climate matter. In this paper we consider how distinct elements of school climate relate to skipping school and cheating on tests. Using survey and administrative data from several statewide Delaware sources, we…

Recent, high-profile, large-scale, preregistered failures to replicate uncover that many highly-regarded experiments are "false positives"; that is, statistically significant results of underlying null effects. Large surveys of research reveal that statistical power is often low and inadequate. When the research record includes selective…

The important role of student agency in collaborative problem-solving has been acknowledged in previous mathematics education research. However, what remains unknown are the processes of agency in open-ended tasks that draw on real-life contexts and demand argumentation beyond "mathematical". In this study, we analyse a video recording…

The poet Tony Harrison has created work for the stage and television, and even assumed the role of poet/journalist, writing newspaper reports in verse from war-torn Bosnia. His work is underpinned by a belief in the political nature of the act of writing. He has generally attracted a non-working-class readership; nevertheless, he has never…

In this article, we show how students' productive struggle on a mathematical task can lead to collective mathematical creativity. We use observable (co)actions and interactions from a video record that features three Grade 6 students in a problem-solving session to document the emergence of collective creativity leading to a mathematical solution.…

The re-emergence of student activism on college campuses in the U.S. has provoked questions about its educative function in higher education. Analysed through the lens of Kolb's experiential learning theory cycle, individual interviews with self-identifying student activists from across the U.S. reveal that activism engages students in learning…

The literature on proof by contradiction (PBC) is nearly unanimous in claiming that this proof technique is "more difficult" for students than direct proof, and offers multiple hypotheses as to why this might be the case. To examine this claim and to evaluate some of the hypotheses, we analyzed student work on proof construction problems…

This descriptive research aimed to know students' problem-solving ability in arithmetic operations on algebra forms through an Indonesian realistic mathematics education, namely Pendidikan Matematika Realistik Indonesia (PMRI), approach in secondary school number 17 Palembang. The learning process, material, and assessment used were principles and…

In this work, we study several closely related problems involving chains, conveyor belts, and rockets, which are described and solved without the application of infinitesimal calculus, or even the concept of mathematical limit. On one hand, the novelty lies not in the problems themselves, but in the method used for their solution, which brings…

This study investigated the strategies students in general chemistry and analytical chemistry courses used before and after instruction to solve a volumetric analysis problem in which the molar ratio was not 1:1. Questions like this have historically been very challenging for high school and undergraduate students. Student writing on open-response…

Singapore students have consistently demonstrated outstanding levels of performance in mathematics and problem solving captured in international assessments. However, these stellar results stand in contrast to Singapore's real-world problem-solving capacities, evidenced by her diffident innovation levels and a limited talent pool with…

When co-witnesses exchange information, false information may be presented, and false memories could be created. This co-witness suggestibility effect has been studied in face-to-face interactions, and little is known about the impact of online discussions on co-witnesses' memories. In two experiments, we explored whether: (1) the co-witness…

Partially specified correlation matrices (not to be confused with matrices with missing data or EM-correlation matrices) can appear in research settings such as integrative data analyses, quantitative systematic reviews or whenever the study design only allows for the collection of certain variables. Although approaches to fill in these missing…

Anchor movements rest on the premise that people- and place-based initiatives can be mutually reinforcing. The community development movement, however, has been haunted for years by the people-place dilemma -- the idea that efforts to help people harm efforts to uplift places and vice versa. Most of the literature on the anchor strategy has…

"Human Impacts on Our Climate" outlines a journey that will steer your students toward authentic problem solving while grounding them in integrated STEM disciplines. Like the other volumes in the series, this book is designed to meet the growing need to infuse real-world learning into K-12 classrooms. This interdisciplinary, three-lesson…
