Learning mathematics through modeling tasks in elementary school: using growth of population context

This study aimed to obtain modeling task to learning mathematics on Elementary School using growth of population context. It used method of development research which consists of three stage, i.e. firstly analysis, secondly design, and lastly evaluation. On the step of analysis, i.e. firstly analysis of student, secondly analysis of curriculum and lastly analysis of mathematical modeling were conducted. On the step of design and product of mathematical modeling tasks were implemented (Hypothetical Learning Trajectory). Then the last stage utilized a evaluation of formative design, i.e., firstly, self-evaluation, secondly, one-to-one, thirdly, expert review, fourthly, small group, and lastly, field tests. The criteria of success of this research were produce local instruction theory of mathematical modeling tasks for elementary school which was valid and practical for learning mathematics. The subjects in this study were three students of SDIT Bina Insani of Ogan Komering Ilir. Data were collected and analyzed utilizing method of analysis of descriptive, i.e., firstly, walkthrough by Experts. They comment on the prototype in term of content and competencies of students. Then, secondly, analyze student's solution and comment on one-to-one and small group activities to get practicality; and lastly, explaining student's solution and comment on the field test to get potential effect. Based on the validation, practicality evaluation, and try-out, We conclude that the designed mathematical modeling task using growth of population context for mathematical learning in elementary school was valid, practical and useful.
