Various tests to check the homogeneity of variance assumption have been proposed in the literature, yet there is no consensus as to their robustness when the assumption of normality does not hold. This simulation study evaluated the performance of 14 tests for the homogeneity of variance assumption in one-way ANOVA models in terms of Type I error…

This case study is aimed at postgraduate and early career researchers who wish to embark on using ethnographic techniques in educational research. The topic in question is school food and its impact upon learning. In this case, it is the social aspect which is being addressed. This research did not aim to address the nutritious element but the way…

Children spend an important part of their time watching animated films on different platforms (cinema, television, internet). Box office figures indicate that this is true at the global level. However, it is not known how children react momentarily to the animated films they watch, and how these reactions fit the content of the film viewed. The…

The Decibel Analysis for Research in Teaching (DART; Owens et al., 2017), a sound-based metric of learner-centeredness, is highly accessible, requires no training, and can be conducted with minimal classroom observations; yet, DART has not been evaluated in comparison with other validated metrics or in consideration of potentially confounding…

This article describes the implementation of an activity with a Predict-Observe-Explain (POE) learning cycle to teach the concepts of velocity and acceleration to physics students aged 17-19. The study indicates how the instructor enacted the activity and provides sample student responses and group discussions. The description includes an example…

This systematic review on data modalities synthesises the research findings in terms of how to optimally use and combine such modalities when investigating cognitive, motivational, and emotional learning processes. ERIC, WoS, and ScienceDirect databases were searched with specific keywords and inclusion criteria for research on data modalities,…

Implicit bias is an issue that all instructors must face in their classrooms; this article describes an academic development method to help instructors address it. The method centres on EQUIP (https://www.equip.ninja), a free, web-based application for performing classroom observations that provides data disaggregated by social markers.…

This article discusses how the teaching of qualitative research in higher education is threatened by the effects of new public management, by academic culture wars and by a growing belief in big data. The controversy over Alice Goffman's book "On the Run" presents one recent example of this. In an effort to counterbalance these…

Students struggle with observing scientifically and connecting observations to scientific theory. This study investigates how students actually use observation in rock classification -- a classical practical task in science education. To describe the level of students' use of observation, data was collected by videotaping 19 small student groups…

The number of trials aimed at evaluating treatments for autism spectrum disorder has been increasing progressively. However, it is not clear which outcome measures should be used to assess their efficacy, especially for treatments which target core symptoms. The present review aimed to provide a comprehensive overview regarding the outcome…

The purpose of this research is to examine cultural difference in Turkish and American preschoolers' play, aggression and victimization behaviours. The research has been performed in a nursery school affiliated to a university in one of the big cities of Turkey and in two nursery schools affiliated to a university in one of the Northern states of…

The Every Students Succeeds Act (ESSA) loosened the federal policy grip over states' teacher accountability systems. We present information, collected via surveys sent to state department of education personnel, about all states' teacher evaluation systems post-ESSA, while also highlighting differences before and after ESSA. We found that states…

"Study" is recently re-invoked as an alternative educational formation to disrupt the learning trap and trope. This paper calibrates "study" and "learning" as two hermeneutic principles and correlates them with "seeing," "hearing," and "observing" as three onto-epistemic modes that…

The debate over whether class size matters for teaching and learning is one of the most enduring, and aggressive, in education research. Teachers often insist that small classes benefit their work. But many experts argue that evidence from research shows class size has little impact on pupil outcomes, so does not matter, and this dominant view has…

This study aims to understand the instructional interactions that foster students' generalizing. By analysing video-recorded lessons from 13 different Grade 3 classrooms in which an early algebra intervention was implemented, activities related to generalizing and students' generalizing activities were identified, and the nature of the…
