APOS Theory Implementation of a Module Contained with Autonomous Character and Mathematics Connection on Algebra Material

---This is a development research of a learning source based on APOS theory. The role of APOS theory is to facilitate framework constructions of an action, process, object, and scheme. This research aims to evaluate the existence of the learning material based on APOS theory and tests its validity and practicability based on the readers’ responses. This is a Research and Development study. The stages consisted of 5 steps: analysis, plan, development, implementation and evaluation. The subjects consisted of the teachers, the parents, and the learners of Primary Schools, Junior High Schools, and Senior High Schools in Lingga Municipality. The variables consisted of the learners’ autonomies and mathematics connections. The quality of the module was obtained from observation, interview guidance, and questionnaire. The findings showed the current learning source existence had not been oriented to APOS theory. The same thing also occurred in the action, object, and scheme stages. The findings also asserted that the develop module was valid and practical. The module had high validity, and an excellent criteria. The responses of both the parents and the teachers showed that the module could be used as a learning reference. The learners responded positively about the module since it was concluded that the module was applied for Primary School until Senior High Schools learners as the learning reference.
