## Abstract

This article is intended to introduce the Mathematical Learning Model of APOS Theory (Computer Based APOS Model). The APOS model has been developed using The Plomp design consist of three initial phase: 1) preliminary research, 2) prototyping phase, and 3) assessment phase. The construction of thr model used the Joyce and Weil models, which consist of five components: Syntax, Social System, Reaction Principle, Supporting System and Impact. The syntax of APOS model consists of phases: Orientation, Practicum, Group Discussion, Class Discussion, Exercise, and Evaluation. The developed APOS model was valid, practical and effective already. The main supporting part of the APOS Model were Worksheets that contain activities in the Orientation phase, Practicum phase, Group Discussion phase, and classroom discussion phase. For Evaluation Phase we used seppareted instruments. APOS model was being implemented in Integral Calculus Course by Mathematics Education Students Semester 3 FKIP UNIB FY 2017/2018. In the Practicum phase, students work with computers using the Maple program for Calculus. Information collected through a postest for the Area of Polygon and Sums of Riemann topics as follows: The number of students who scored ≥ 80 was 33,33%; The number of students who scored ≥ 60 and <80 were 33,33%; The number of students who scored <60 was 33,33%. Information collected through an open questionnaire about which phase did the students understood the materials as follows: the number of students can understand the material in phase: Praktikum = 22.22%, in Small Group Discussion = 30, 56%, in Classroom Discussion phase = 33, 33% , and in Exercise phase = 13, 09%. It can be conclude that the model is good for improving student learning outcomes, and to improve students' ability in discussion.
