pH buffers are used extensively in research and industry making them an important chemistry topic for students to learn. This qualitative study uses the phenomenographic method and a resource theoretical framework to provide the first insights into how students approach conceptual buffer problems. Three scaffolded buffer question sets were…

The purpose of this study is to present a set of empirically derived effect size distributions in order to provide field-based benchmarks for assessing the relative effects of interventions aimed at reducing challenging behavior or increasing engagement for young children with and without disabilities. We synthesized 192 single-case designs that…

In Bayesian statistics, the most widely used criteria of Bayesian model assessment and comparison are Deviance Information Criterion (DIC) and Watanabe-Akaike Information Criterion (WAIC). A multilevel mediation model is used as an illustrative example to compare different types of DIC and WAIC. More specifically, the study compares the…

John Dewey is well-known for claiming that school education is all about developing the ability to think. There is nothing else for schools to do so far as students' minds are concerned. Thinking is not only the aim of education for Dewey, however, but the means of achieving it. This is not because it is the method to be preferred. Rather, as…

A tutor and a student together propose a model for integrated student and staff engagement that concentrates on developing students' core abilities. They build upon their respective experiences of self-managed problem-based learning and of the purposeful promotion of core abilities. They explore the potential of collaborative interaction between…

In this report we show an investigation of how high-school students learn strategies to find intermediate numbers in an interval to understand the property of numerical density. Research has shown that some high-school students have difficulty in understanding this property. To mitigate this difficulty, we proposed a Hypothetical Learning…

This research contributes to the need to identify and expand learning environments that encourage undergraduate students to develop collaborative work skills and apply their classroom knowledge to solve real-world problems. Using qualitative methods, we examine the effects of the interaction between two teams of students when solving a…

Students with emotional and behavioral disorders (EBD) can exhibit severely challenging behaviors that lead to events of crisis in an inclusive classroom. This article provides practitioners with an overview of the cycle of dysregulation experienced by some students with EBD. The article includes descriptions of stages in the dysregulation cycle,…

This article presents results from a self-report survey of misconduct behaviours and the stress students (n = 916) experienced at one Canadian community college. Results showed that students engaged in a variety of contract cheating behaviours, and experienced a myriad of stressors both in and outside the college context, including traumatic life…

The two-year institution where I teach first-year composition serves multilingual students who excel, keep pace, or fall behind. In addition to these students, there are one or two whom I identify as "promising but struggling multilinguals." While this small but everpresent contingent attend regularly, submit work somewhat consistently,…

The importance of student-teacher relationships is well established. However, research suggests that students in special education tend to experience lower quality student-teacher relationships than their peers in general education. Of particular importance is the developing research indicating that students with emotional and behavioral disorders…

N-of-1 trials, a special case of Single Case Experimental Designs (SCEDs), are prominent in clinical medical research and specifically psychiatry due to the growing significance of precision/personalized medicine. It is imperative that these clinical trials be conducted, and their data analyzed, using the highest standards to guard against threats…

Investigating the optical properties of various chemical compounds using UV-vis spectrophotometers is an essential part of education in chemistry. However, commercial spectrophotometers are usually treated as "magic black boxes", where the dominant majority of optical elements are hidden "under the hood". This often limits…

Past research suggests that children, particularly those with autism spectrum disorder, with general behavioral inflexibility to objects, persons, and environments may be at risk for feeding problems. However, questions remain about whether feeding problems are better predicted by behavioral inflexibility or sensory sensitivity, and whether…

Recent research has begun to explore the specific social challenges experienced by persons with Tourette syndrome (TS); however, it does not specifically address the challenges that often arise interpersonally as part of people's communicative interactions and these interactions socially construct the individual and collective well-being of all…
