Missing data are ubiquitous in studies examining preventive interventions. This missing data need to be handled appropriately for data analyses to yield unbiased results. After a brief discussion of missing data mechanisms, inappropriate missing data treatments and appropriate missing data treatments, we review the current state of missing data…

The tutor-web is an open-source learning environment designed to be used for teaching mathematics and statistics. The system offers thousands of exercises at high school and university level, and has been used for a decade to teach introductory statistics courses with good results. A new component has recently been added to the tutor-web so that…

The aim of the research was to determine what relations occur between the stress experienced by parents in the relationship with their children and the personality traits that they shape in them. Personal characteristics that parents shape in their children have been classified into metatraits described in the Circumplex of Personality model. The…

A "Cone of Uncertainty" has become ubiquitous in hurricane forecasting, encompassing the likeliest possible path that a storm might take as it approaches landfall. These forecasts are crucial because they help government agencies at all levels prepare even in these far-from-certain future conditions. Although individual institutions have…

The increasing datafication of teachers' work and schooling practices as evidenced through various metrics of student testing and school improvement measures have continued to grow unabated across many OECD Countries. Such practices have been fuelled by global competition for league tables such as the Programme for International Student Assessment…

I describe a kinesthetic activity about oxygen handling by hemoglobin with two specific goals: (1) to help students gain a better understanding of how hemoglobin properties affect oxygen delivery and (2) to improve the ability of the students to actually read the hemoglobin oxygen-binding curve. The activity makes understanding oxygen delivery…

This reflection seeks to explore the role that power plays both in schooling and in research, specifically through the use of action research. The authors began this process in informal conversations reflecting on their personal experience with action research methods. Qualitative methods were then used with the authors using semistructured…

This study examined caregivers' longitudinal reports of adolescent multiracial categorization across the ages of 9.5, 10.5, and 14 years, and adolescents' reports of their own multiracial categorization at the age of 14 years. A portion of caregivers' reports of adolescent multiracial status were inconsistent across the years of the study; some…

Background: Britain is rich in longitudinal population cohort studies that posit valuable data resources for social science. However, education researchers currently underutilize these resources. Aims: The current paper (1) outlines the power and benefits of secondary data analyses for educational science and (2) provides a practical guide for…

Preregistration and registered reports are two promising open science practices for increasing transparency in the scientific process. In particular, they create transparency around one of the most consequential distinctions in research design: the data analytics decisions made before data collection and post-hoc decisions made afterwards.…

Writing and communication researchers are in the early stages of developing procedures for reusing and maximizing the analytical potentials of qualitative data. Contributing to this effort, we critically reflect on our methodological decision-making process in developing innovative procedures for cross-analyzing two distinct studies. Our…

The past 20 years have seen the steady 'datafication' of school systems -- i.e. the rendering of key aspects of school practice into data that is digitally collected, processed and circulated. In contrast to assumptions of 'data-driven' schools as sites of more efficient and automated forms of data work, this paper examines the extensive human…

Data and its applications are increasingly ubiquitous in the rapidly digitizing world and consequently, students across different disciplines face increasing demand to develop skills to answer both academia's and businesses' increasing need to collect, manage, evaluate, apply and extract knowledge from data and critically reflect upon the derived…

E-learning environments can store huge amounts of data on the interaction of learners with the content, assessment and discussion. Yet, after the identification of meaningful patterns or learning behaviour in the data, it is necessary to use these patterns to improve learning environments. It is notable that designs to benefit from these patterns…

The COVID-19 pandemic has been one of the greatest challenges faced for a very long time. However, it has also presented educators with novel opportunities for teaching, none more so than in science. There are the obvious links between COVID-19 and the body of scientific knowledge that curriculum designers think educators should help students to…
