The middle years of school represent a time of educational turbulence, serving to marginalise some students from educational opportunities. Much research has focussed on individual cognitive factors influencing educational engagement, with less attention directed towards social interactions. Theoretically positioned within an expectancy-value model of achievement motivation, this study draws on the lived experience of a 12-year-old student within an alternative school in South Australia, Australia, to explore how social encounters may contribute to educational marginalisation. Findings from a narrative case study employing a semi-structured interview suggested that connections exist between social influences, such as interactions with teachers and peers, and subsequent achievement motivation. This study suggests that social interactions are critical determinants to an individual's educational engagement, affecting educational ability, expectancy and value beliefs.
