The literature on teacher leadership tends to omit mention of the dark side of leadership. This is troubling since, after all, examples of bad leaders come readily to mind. This paper delves into the literature on bad leadership, illuminating it with reference to Iris Murdoch's moral psychology, to elaborate an explanation as to why leaders often…

The paper presents a framework for school guidance in the twenty-first century that focuses the guidance approach, on promoting lifelong learning and takes into account the impact of VUCA (volatility, uncertainty, complexity, and ambiguity). It outlines the goals, objectives, and key players involved in guidance approach and provides a structured…

This contribution deals with effect measures for covariates in ordinal data models to address the interpretation of the results on the extreme categories of the scales, evaluate possible response styles, and motivate collapsing of extreme categories. It provides a simpler interpretation of the influence of the covariates on the probability of the…

An essential aspect of scientific practice involves grappling with the generation of predictions, representations, interpretations, investigations, and communications related to scientific phenomena, all of which are inherently permeated with uncertainty. Transferring this practice from expert settings to the classroom is invaluable yet…

This article focuses on "uncertainty"--ways in which scientists recognize and analyze limits in their studies and conclusions. We distinguish uncertainty from (un)trustworthiness--ways in which scientific reports can be affected by conscious deception or unconscious bias. Scientific journal articles typically include analyses and…

This paper aims to broaden the scope of the construct concept image by addressing the mathematically oriented notion of "solution of an algebraic equation." The notion solution of an algebraic equation is not mathematical per se, but it is most prevalent in mathematical communications and in mathematics education. The paper describes…

Much knowledge production, both academic and non-academic, is driven by a need to simplify the world in order to enable people to navigate the complexities of everyday life. Such simplifications not only risk offering less reliable representations of the world, they can also turn into disruptive and harmful images of the world. In this article,…

The final observable product of a successful doctoral programme is typically a thesis that has been critically examined by senior academics and considered to demonstrate a significant contribution to knowledge. However, it is a conviction underpinning this special issue that the doctorate should be acknowledged, explored and understood as a…

In this article, examples are shown to demonstrate how open-ended mathematical activities can be used in the classroom. Open-ended activities give students opportunities to apply their understanding in unfamiliar contexts without the pressure of finding one perfect solution.

The growing use of analytics has increased the demand for more highly data literate graduates. Awareness of ambiguity in data has been suggested as a new data literacy skill. Here, we describe a student-centered semester-long project that can be used to teach this skill in an introductory analytics or database course. The project requires students…

Advisors of student organizations face many challenges, including holding students accountable while respecting their autonomy, dealing with challenges of diversity, equity, and inclusion, and navigating their lack of training. Coupled with other professional obligations, it is common for advisors to feel stressed and under-prepared in their…

Turning educational ideas into meaningful learning requires planning for uncertainty. This article presents Bakhtin's key concept of "eventness" as an essential aspect of defining dialogic space. To Bakhtin an event is something happening here and now, with a degree of open-ended uncertainty tied to what will happen next. Acknowledging…

Uncertainty in education, both general and special, has long troubled educational researchers, reformers, and practitioners. Responding to students with special (atypical) educational needs is an example of decisions that are prone to error. Although some efforts to reduce uncertainty in education are reasonable and helpful, efforts to eliminate…

This conceptual essay draws on the advice for actors offered by David Mamet and Sanford Meisner in order to highlight how uncertainty is a dilemmatic feature of both acting and teaching. This essay argues that perhaps the only way to prepare for uncertainty (either on the stage or in the classroom) is to be open to uncertainty and to be willing to…

The increased distribution of fake news on internet and social media raises concerns for democratic processes. Sometimes, argumentation in deceptive information is built on numbers, which gives reason to include mathematics when working with fake news in education. In this paper, I suggest a tool to facilitate students' critical thinking related…
