ab: Summary: This article provides how to implement the use of Realistic
Mathematics Education (RME) in teaching function at a school to improve
students’ mathematization for their mathematical thinking using
technology. This study was planned to get research results using the
mixed methodology with quantitative and qualitative methodologies, 120
middle school students participated in the study to bring us data about
their mathematical achievement and disposition. Through the data
analysis used ANCOVA, the students with the experiment of the
mathematization and technology excelled the other groups of students
who were not provided with technology or both of them. In analysis of
the questions of the achievement lest, the problems for vertical
mathematization were presented harder for the students than the other
problems for horizontal and applicative mathematization. The technology
environment might have helped students manipulate the application of
real-life problems easier. This means that teachers can put more
careful assignment on vertical mathematization using technology. We
also explored that learning and teaching under RME using technology
encouraged students to refine and develop their informal functional
concept and pursue higher thinking of formalization. The study results
in a lot of resources for teachers to use into their teaching
mathematics for improving students’ mathematical thinking.
