The Pearson correlation coefficient can be recovered from the two least squares regression lines y[with circumflex] = b[subscript 0] + b[subscript 1]x and x[with circumflex] = a[subscript 0] + a[subscript 1]y without any data. This can be done both algebraically and geometrically. This can be done without data even when the scales of the variables…

This study explored the interactional aspects of text messaging on mobile phones for youth with complex communication needs. A qualitative case study design was used to investigate aspects such as reasons, place, timing of communication, content and communication partners. Data were gathered from seven youth with complex communication needs…

The COVID-19 pandemic has revealed substantial gaps in communication access for patients across hospital settings. With the rise in positive cases globally, the need for communication enhancement strategies, including augmentative and alternative communication (AAC), has emerged as a critical need. Many resources exist that describe AAC assessment…

In this article, the authors share ideas for harnessing the power of mathematics and children's literature to understand social justice issues with upper primary students, which can be adapted for younger students. The authors focus on the critical issues of food scarcity and waste. Children's literature and current data are purposefully employed…

Today's workplace is going through tremendous changes and becoming highly complex in terms of technology and tasks. Thus, critical problem-solving skills are key to creating a sustainable career in today's global economy. Indeed, the global COVID-19 epidemic has amplified the need for these skills in almost all occupations. This study examined the…

The simple vehicle routing problem (VRP) is a common topic of discussion in introductory operations research/management science courses. The VRP can be framed in a variety of ways, and it can be difficult to solve to optimality. For solution purposes, introductory textbooks demonstrate how Excel's Evolutionary Solver (ES) add-in produces a…

COVID-19 outbreak brought about many challenges including the shifting of university assessments to conduct in online mode. This research study tries to explore the impact of newly designed online formative assessments on students' learning, in a Plant Physiology course. The designing of assessments were carried out focusing on constructive…

Teaching data analysis by providing students with real-world problems and datasets allows students to integrate a variety of skills in a situation that mirrors how data analysis actually works. However, whole data analyses may obscure the individual skills of data analytic practice that are generalizable across data analyses. One such skill is the…

This paper reports on a project that sought to enhance problem-solving practices within a cluster of primary schools. In-service teachers' description of their approach to problem-solving suggested it was treated as an isolated practice that occurred after concepts had been taught; often focusing on teaching particular problem-solving strategies…

Numbers and variables often follow the same principles of arithmetic operations, yet numbers can be computed to a value whereas variables cannot. We examined the effect of symbols--numbers versus variables--on middle school students' problem-solving behaviors in a dynamic algebra notation system by presenting problems in numbers (e.g., 3+5-3) or…

A concerning number of students enter kindergarten facing an intractable variation of mathematics difficulties (MD). This study investigated the impact of an explicit, core kindergarten mathematics program on the mathematical outcomes of kindergartners who demonstrated severe MD at kindergarten entry and examined whether these students improved…

This report examines features of states' expulsion and suspension prevention policies, based on survey responses and interviews with selected states. The results point to the widespread efforts states are making to develop and implement expulsion prevention policies. Features of policies are varied, and include supports for programs (e.g.,…

All Texans deserve access to affordable, high-quality learning opportunities that lead to credentials of value--postsecondary credentials that will unlock their potential, help them provide for their families, and pursue their dreams. Helping students understand the financial choices they will make before, during and after their postsecondary…

Many school leaders with decision-making authority over discipline have been historically traditional in their approach to misbehavior with the default consequences involving classroom removals and the wide-spread use of zero-tolerance policies (Skiba et al., 2014; Skiba, 2015). Unintended negative consequences have emerged as a result of these…

The purpose of this narrative inquiry is to understand the teachers' experiences of working with students who have faced trauma or traumatic events. The number of children facing trauma exposures to violence, crime, and abuse in the classroom has increased. The insufficient knowledge among educators about the effect of trauma on students lays the…
