The effectivity of APOS model based worksheets on the improper integral

Abstract

The APOS model is a mathematical learning model based on APOS theory, with syntax consisting of phases: Orientation, Practicum, Small Group Discussion, Classroom Discussion, Exercise and Evaluation. The APOS model has been implemented in Integral Calculus courses by Class A Semester 3 Students in Mathematics Education Study Program FKIP UNIB 2017/2018 TA. Specifically for the improper integral subject, there are five students who choose to discuss improper integral LK independently in group. The purpose of this study is to see the effectivity of APOS Model Based Worksheets on the Improper Integral subject matter. The effectivity was analized from the mastery of the improper integral by giving a test, if the five students were still master the material, after the launch time of up to two months. The instrument used were a test, and an open questionnaire. From the results of this study, we conclude that mastery of the material was in category “very effective”. Based on the polling from the questionnaire, it can be concluded that the worksheet based on the APOS Model was effective to help the development of independent, diligent, thorough, resilient, responsible, jointly active, helpful, critical and creative characters of students. So, the Apos Based Worksheets was effective to use in calculus class on the Improper Integral material.
