Executing Learning Activities and Autonomy-Supportive Instructions Enhance Autonomous Motivation.

This study investigated situational changes in learners' degree of autonomous regulation during other-initiated learning activities and examined the influence of the instructional style on such changes. To this end, relative autonomous motivation of 172 fifth to seventh grade students was measured before, during and after execution of a musical learning activity. It was experimentally manipulated whether students were instructed in an autonomy-supportive or a controlling style.
