In addition, whereas the impact of autonomy support and structure was examined, the
impact of specific aspects of autonomy support and structure (e.g. providing a rationale for
a task that explains task relevance or using a roadmap) on motivation and learning performance
has not been studied. Follow-up work should investigate the contributions of specific aspects of autonomy support and structure to clarify the mechanisms underlying the relationships found in this study. This is also the case for metacognitive skills and self-regulated learning.
