Quadratic modeling problems are commonplace in high school mathematics courses; they typically situate quadratic patterns of change and their corresponding parabolic graph within real-world contexts. Traditional approaches to this type of problem lend themselves to making connections across different representations (e.g., Garofalo and Trinter…

"Autism at-a-Glance" is designed for high school staff members supporting students on the autism spectrum, as well as family members of adolescents on the autism spectrum. This issue focuses on understanding and improving the communication skills of adolescents on the autism spectrum. The content specifically targets the needs of…

A picture is worth a thousand words. This statement is especially true in mathematics teaching and learning. Visual representations such as pictures, diagrams, charts, and tables can illuminate ideas that can be elusive when displayed in symbolic form only. The prevalence of representation as a mathematical process in such documents as…

Boys are commonly associated with disruptive behaviour and physical fighting at school. Explanations for this behaviour range from naturalistic "boys will be boys" approaches to analyses which focus on the social construction of masculinity and emphasise the gendered nature of boys' behaviour. Whichever view holds sway, it is often…

Debating has been around for a long time, with some pretty spectacular results. Look at Socrates, who was put to death in 399 BCE for corrupting the youth of Athens; his accusers could not forgive him for incessantly questioning their beliefs and making "the worse appear the better cause." More recently, debating has morphed into a sport for the…

Students enter the geometry classroom with a strong concept of fairness and a sense of what it means to "play by the rules," yet many students have difficulty understanding the postulates, or rules, of geometry and their implications. Although they may never have articulated the properties of an axiomatic system, they have gained a practical…

This study sought to determine whether coaches' immediacy behaviors serve as predictors of athletes' satisfaction and team cohesion levels. Participants included 307 male and female high school athletes who completed measures assessing perceptions of their coaches' verbal and nonverbal immediacy behaviors, as well as their own levels of…
