A brief overview of RME in Indonesia
Before we go to what RME is, let me remind you about your
mathematics subjects when you were at elementary, secondary or high school; do
you still remember who taught you math and can you solve some mathematical
problems of elementary student’s level when your little brother or sister ask
for your help to solve his or her homework? Did you hate mathematics or even do
you still hate mathematics?
In Indonesia, not only was the problem of mathematics
informed formally (Marpaung, 1995) that most pupils in a number of selected
primary schools in Yogyakarta were afraid of mathematics, but also the result
of mathematics education for 16 different urban and rural secondary schools in
several provinces was very low based on finding from two diagnostic test carried
out by Suryanto (1997) and Somerset (1996). He pointed out that mathematics
teachers less confident and lack of smile so the classroom situation have no
interaction and pupils have no chance to communicate their solution (
Zulkardi). Seeing mathematics like an evil or monster makes it difficult to
learn mathematics due to the feeling of scary toward mathematics. However,
lacking of understanding of teachers on the contents and pedagogic of
mathematics is also one of factors that make pupils hard to learn mathematics.
Too many exercises and homework to be solved, rules to be proved and lack of
applications in their daily life get pupils had poor attitude toward
mathematics.
In an attempt to combat the low achievement and poor
attitude toward mathematics, hence, a new approach in mathematics education
that can overcome those problems is needed. one of the promising approaches
toward the teaching and learning of mathematics thought to address these
problems is realistic mathematics education (RME).
The philosophy of RME
Mostly determined by Freudenthal’s view on mathematics
(Freudenthal, 1991), two of his points of views on RME are: mathematics must be
connected to reality; and mathematics should be seen as human activity.
Firstly, mathematics must be close to children and be relevant to everyday life
situations. However, the word ‘realistic’ refers not only just to the
connection with the real-world, but also to the problem situations which are
real in students’ mind. Secondly, the idea of mathematics as a human activity
is stressed. Mathematics education organized as a process of guided
reinvention, where students can experience a similar process compared to the
process by which mathematics was invented. Concepts of mathematization as a
guide are used in this reinvention process and later it is categorized by
Treffer (1991) into horizontal mathematization and vertical mathematization.
Principles and Characteristics of RME
the characteristics
of RME are historically related to three Van Hiele’s levels of learning
mathematics (de Lange, 1996). Assuming that the process of learning process, it
proceeds through three levels: (1) a pupil reaches the first level of thinking
as soon as he or she can manipulate the known characteristics of a pattern that
is familiar to him or her; (2) as soon as he or she learns to manipulate the
interrelatedness of the characteristics,
he/she will have reached the second level; (3) he/she will reach the
third level of thinking when he/she starts manipulating the intrinsic characteristics of relations. Traditional
instruction is inclined to start at second or third level, while realistic
approach starts from first level. Then in order to start at the first level
dealing with phenomena that are familiar to students, Freudenthal’s didactical phenomenology that learning should start
from a contextual problem, is used. Furthermore, by the guided reinvention principle and progressive mathematizations,
students are guided didactically and efficiently from one level to another
level of thinking through mathematization.
The combination of three Van Hiele’s levels, Freudenthal’s
didactical phenomenology and Treffer’s progressive mathematization result in
five basic characteristics of realistic mathematics education or five tenets of
RME (de Lange, 1987, Gravemejer, 1994). In brief those are:
- Use of contextual problems (contextual problem
figure as application and as starting points from which the intended
mathematics can come out.
- Use of model or bridging by vertical instruments
(broad attention is paid to development models, schemes and symbolization
rather than being offered the role or formal mathematics right away).
- Use of student’s contribution (large
contributions to the course are coming from student’s own constructions, which
led them from their own informal to the more standard formal methods).
- Interactivity
(explicit negotiation, intervention, discussion, cooperation and evaluation
among pupils and teachers are essential elements in a constructive learning
process in which the student’s informal strategies are used as a lever to
attain the formal ones).
- Intertwining of learning stands (the holistic
approach implies that learning strands cannot be dealt with as separate
entities; instead of intertwining of learning strands is exploited in problem
solving.
Strategies for introducing RME in teacher education in
Indonesia
In the country where RME originally has been developed and
implemented for about 3 decades in the Netherlands, there are also positive
results that can be used as indicators that RME might be promising to increase the quality of mathematics education. For
instance, the results of the Third International Mathematics and Science Study
(TIMSS) showed that pupils in the Netherlands gained high achievement in mathematics
education which was ranked 6^{th} in 38 participating countries and the
gap between smart pupils and weak ones was very small, while Indonesia, the
achievement of pupils in mathematics education was ranked 34^{th} out
of 38 participating countries (Mullis et al., 2000). Thus, “mathematics for all’
which is only a slogan for some countries including Indonesia has been achieved
in the Netherlands. Still, these positive results could be achieved not in
short-term but in the long term endeavor.
Based on the explanation above, RME looks promising to be
introduced and implemented in Indonesia because it could increase pupil’s
understanding and motivation toward mathematics. For instance, RME content
materials are developed using the contexts that are experimentally real to the
pupils. Pendidikan Matematika Realistik Indonesia (
PMRI) is an adapted RME founded
by PMRI team promoted by Prof. R.K Sembiring and officially launched in 1998 to
reform mathematics education in Indonesia. This team results in cooperation
between Directorate General of Higher Education (DGHE) or DIKTI and NESO
Indonesia that is an International Master Program on Mathematics Education
(
IMPoME). This program is under collaboration with between Freudenthal
Institute Utrecht University and Sriwijaya University and Surabaya State
University.
