Ross, John A.; Bruce, Catherine D. – International Journal of Mathematical Education in Science and Technology, 2009
Students have difficulty learning fractions, and problems in understanding fractions persist into adulthood, with moderate to severe consequences for everyday and occupational decision-making. Remediation of student misconceptions is hampered by deficiencies in teachers' knowledge of the discipline and pedagogical content knowledge. We theorized…

Hawley, Patricia H.; Little, Todd D.; Card, Noel A. – International Journal of Behavioral Development, 2007
Recent theory on social dominance suggests that aggressive individuals should be socially successful if they also display prosocial behavior. The combination of coercive and prosocial strategies of resource control (i.e., bistrategic control) is thought to facilitate hierarchy ascension. Adolescents (N = 929, grades 7-10) were queried about the…
