Single-case designs provide an established technology for evaluating the effects of academic interventions. Researchers interested in studying the long-term effects of reading interventions often use curriculum-based measures of reading (CBM-R) as they possess many of the desirable characteristics for use in a time-series design. The reliability…

Self-concept research in early adolescence typically measures young people's self-perceptions of competence in specific, adult-defined domains. However, studies have rarely explored young people's own views of valued self-concept factors and their meanings. For two major self domains, the active and the social self, this mixed-methods study…
