means a learning method which fit to the students'
characteristic. Realistic mathematics education is
one type of method which can be applied to the
module. So, there will be a development of
mathematics bilingual module focusing on algebra
and arithmetic with the help of realistic mathematics
education in grade VII junior high school.
2 LITERATURE REVIEW
To develop a module, we need some theory which
supports the content. The researcher thinks that these
theories have been encouraged the script.
2.1 Module Development
Houston and Howson said a module can be
interpreted as some activities which certain to help
students easier in their learning (Wena, 2010).
While, Surahman said a module is the smallest type
of learning which studied by students individually
(self-instructional) (Prastowo, 2011). So, a module is
an activity which interprets to help students in
learning individually. There is some characteristic of
a module which is self-instructional, self-contained,
adaptive, and user-friendly. Self-instructional means
provide material in worksheet and communicative.
Self-contained means to provide complete material
in one chapter. Adaptive means a learning resource
should follow by good information technology.
While user-friendly means every information in a
module could be understood easily by the students
(Asyhar, 2011). Beside the definition of a module,
this research is about how to develop a mathematics
bilingual module. The development of mathematics
bilingual module means a science and technology
activity which is used to get a product prototype and
analyze design methodology to increase small
learning as a resource for students and teachers with
two languages. There are steps of how to develop a
mathematics module are (1) analyze the basic
competencies and indicators so that the purpose can
be achieved. (2) decide the content and design and
(3) write from the opening, content, and closing.
2.2 Realistic Mathematics Education
Realistic Mathematics Education is a kind of
learning mathematics approach theory which
develops from Dutch. This theory is invented by
Hans Freudenthal who said that mathematics is a
human activity and related to human reality
(Gravemeijer, 1994). According to Hans, students
should not accept mathematics concept passively,
but a teacher should give them chances to reinvent
mathematics by guiding (Apiati, 2017). The
reinvention means there is a relation between
mathematics and the real world. Blum and Niss said
that a real world is everything in real life or habit
which linked to mathematics (Hadi, 2017). Two
types of mathematization in realistic mathematics
education are vertical and horizontal
mathematization. A vertical mathematization starts
with contextual problems and rearranges according
to a procedure to solve the problems. A horizontal
mathematization also starts with contextual
problems but students may solve their symbol and
language which can be different from one another
(Ningsih, 2014). Realistic Mathematics Education
learning approach has five characteristics which are
(1) the use of contacts, starts a lesson by giving a
real-world problem. (2) construction, students can
explore their knowledge to solve the problems
freely. (3) the use of a model, students develop
another mathematization model as a bridge to formal
mathematics. (4) interactivity, students can discuss
the problems with their friends. (5) Intertwinement,
the learning material has a relationship with the
previous and next chapter (Wijaya, 2012).
2.3 Methods
Research and Development are used in this research.
Sugiyono said that research and development is a
kind of research method where it used to produce a
product and tested the effectiveness (Sugiyono,
2015). The design research is shown in figure 1.
The design research is separated into the
procedure of module development in three stages
which are Preparation Implementation, and
Analysis. The preparation stage, the researcher
arranges the module with many kinds of learning
resources like school book, realistic mathematics
education book, and information from the internet.
Besides that, the researcher also prepared some
score table for expertise and studentsβ validation. In
the implementation stage, it was followed liked the
design research.
First, identify the potential and problem, junior
high school students have the ability to communicate
in English, active, and less understand in algebra and
arithmetic. Within those potentials, there is a
problem from the students who have less
understanding in both chapters and a school does not
have a mathematics bilingual module as the learning
