Motivation in Context: Intraindividual Variability in Day-to-Day Classroom Learning

This dissertation focuses on how student motivation emerges and changes in the day-today classroom context. Drawing on self-determination theory, it proposes that specific features of the classroom instruction—and of what teachers say and do—may either support or frustrate students’ need for autonomy. Autonomy-supportive instruction is hypothesized to enhance interest and competence perception in the classroom. At the same time, students’ classroom experience is affected by their individual resources such as interest, integrated values, or positive self-concepts. Given the dynamic nature of the classroom context, the overarching aim of this dissertation is to take a short-term, intraindividual approach to understand how both the learning situation and individual motivational resources shape students’ motivational experience. The dissertation comprises three manuscripts investigating student motivation in a pre– post design over a 1 year period, including a 3-week lesson-specific measurement phase in which students’ classroom experience were assessed daily. Drawing on interest theory, manuscript I shows that stable individual interest and perceived characteristics of classroom instruction make distinct contributions to students’ day-to-day interest experience. Similarly, manuscript II shows that both domain-specific self-concept and perceived characteristics of classroom instruction shape students’ felt competence in lessons. In particular, empirical support was found for the hypothesis that cognitive autonomy support has effects on student motivation over and above the effects of autonomy-supportive climate and controlling behaviors. From an individual differences perspective, manuscript III shows that some students experience higher day-to-day fluctuation in their domain-specific self-concepts than others. Self-concept instability was found to be associated with test anxiety and to predict lower school grades 1 year later. Taking a short-term intraindividual approach, this dissertation thus shows that both the learning situation and individual student resources contribute to motivation in context. An understanding of how motivation evolves over different contexts and time frames of instructional events, in everyday classroom life, and across the school career can usefully inform theories of motivation in context.
