The purpose of the study was to investigate the structural relationships among self-determination
motivation to learn, metacognition, self-directed learning ability, learning flow, and school
achievementofhighschoolstudents.Theparticipantsofthestudywere427firstgradehighschool
students.Structural Equation Modeling(SEM) using AMOS 7.0 was employed to examine the
relationships.Themajorfindingsofthestudywereasfollows;self-determinationmotivationtolearn
