Conceiving the construct "social-emotional learning climate" as an embodiment of Illeris' contemporary learning theory, this paper serves dual purposes. First, it examines recent music education literature, which identifies issues of competence and institutionalised pedagogic practice in secondary school music settings that result in adolescents' inability to target and develop personal locus of control over learning, and the subsequent rejection of the learning environment. Second, it details findings, discussion and pedagogic implications from the author's dissertation study exploring music teacher formative influence upon and student experience of Illeris' theory of learning process within three Canadian secondary school learning settings integrating informal learning practices.
