We investigated how 5th-8th graders' self- and peer-identified withdrawal motivations predicted peer-reported peer relationships and aggression. Participants (N = 221; 47% male) provided self-reports and peer-nomination data (we analyzed 339 students' nominations). We hypothesized shyness, unsociability, and avoidance would predict low peer liking…

The promotion of mathematical literacy depends on understanding the variables associated with mathematics learning. The purpose of the current research was to explore relationships between mathematics achievement with sources of mathematics self-efficacy and perceived mathematics achievement expectations of parents, teachers, and friends in middle…
