Based on the observations on the students in department of Mathematics Education UNRIKA, especially in Vector Analysis course, it is found that the students find it difficult to understand the material. This study aimed at knowing the effectiveness on the use of constructivism-based vector analysis module. The research design was using one shoot case study. The research population was 41 students with saturated sampling technique. The research instrument was using essay test consisting of five questions that hadtested its validity and reliablity. The hypothesis testing was using one sample T-test assisted with SPSS Statistics 20.0 in the significant level of 5%. Based on the analysis results, it was obtained sig (0.007) < α (0.05), so it can be concluded that the use of constructive-based vector analysis module to wards the learning outcomes for 4 th semester students in department of Mathematics Education UNRIKA in academic year of 2016/2017 can be categorized as moderate. Keywords: constructivism , effectiveness, module, vector analysis 1. INTRODUCTION Based on the United Nation Development Program (UNDP) report in 2005, the quality of Human Resources (HR) in Indonesia is ranked 109th from 117 countries [1]. It is very urgent to improve the teacher quality to support HR development by enhancing the education sectors. To realize this, mathematics that has been the most common prerequisites in education need to be enhanced. The pre-service teacher of mathematics should gain knowledge on vector analysis material including constant vectors, vector functions, differential vectors and vector integral. Vector analysis is one of the compulsory subjects for 4 th semester students in department of Mathematics Education UNRIKA. The benefit of this course is to prepare the teaching about the vector concept in the secondary and senior high levelor vocational high school. The basic vector basics have been taught in high school, especially for the students of science. It is presented in two subjects such as physics and mathematics, two subjects that are considered as the most difficult course for the students [2][3]. Vector is a subject that required high accuracy. It means this subject should be presented as best as as possible with a fun method. In university level, vectors learns in the course of vector analysis. The vector analysis courses have some prerequisites, i.e. Calculus I, Calculus II and Advanced Calculus [4]. As Mathematic decipline, vector analysis is a branch of science that studies the real analysis of vectors in two or more dimensions. Vector analysis encompasses vector and scalar operations, vector fields and scalar fields, differentiation &
