“…As a result, music education researchers have examined young adolescents’ motivation to participate in music as one line of middle school-focused inquiry (Bennetts, 2013; Campbell, 2009; Kennedy, 2002; Power, 2008; Saunders, 2010; Warnock, 2009).

Despite these many avenues of investigation around the teaching of young adolescents, the educational principles guiding the everyday choices made by music educators when working with young adolescents, particularly in non-ensemble settings, remain unclear.…”
