This research aims to construct a learning simulation model for quadratic equations topic in the Grade1 High Scholl with “matematisasi berjenjang” approach. This simulation model contains the learning scenario and recording of learning activity implementation in class. This research used classroom actions reseach method and did in the Grade 1 Class Sang Timur High Scholl Yogyakarta.
The Early Scenario Learning Design which is constructed needs evaluated and repaired from management learning aspect in class, in order to become the Final Learning Scenario. The teacher should be given instruction briefly, manage cooperative class with calm and patient , give helping for student with appropriate according the student stage activity, conscious that time scheduling in the Early Scenario Learning Design is not strict. The student seems ready to to learning activity with change method, can appear some problem solving strategy for the given problems, present the result of working bravely and discuss them, the quickness and readiness student in activities stages which is happened are vary.
