This research have aimed at investigating the progress
of students learning on multiplication fraction with natural number through the
five activity levels based on Realistic Mathematics Education (RME) approach proposed
by Streefland. The object for this research were students fifth grade in SDN
179 Palembang.
In the first level, students started to produce
their own fraction and recalled back their knowledge about the meaning of
fractions as part of a whole. Related to the first tenet of RME, the researcher
used the measurement (length) activity as contextual problems. The researcher
thought that was a good context that has allowed students to structure and to
mathematize following the five activity levels.
In the second and third levels, students were
generating equivalencies and operating through mediating quantity. Problem
situation in which the students drew the number line as a representation of
string of yarn had strongly generative nature. Connected to the second tenet of RME, namely the use of models, the use string of
yarn here was a bridge to the number line model which was in more abstract
level. Through using the material, the students are given the opportunity to
actively contribute to their own mathematics.
The fourth and fifth level gave opportunity to
students to use their strategies that can be used to developed the next
learning process. Connected to the third tenet of RME, namely the use of students own creation and
contribution, the use of number line as a model of measuring situation
transformed into a model for more formal reasoning.
Connect to the fourth tenet of RME, namely interactivity, the classroom setting was
elabotared where the students could share their thinking in the class
discussion. And for the last tenet of RME, namely intertwinement, the researcher found that fraction have close
relation with fraction.
To sum up, from the explanation above about this research,
it was obvious that this study has taken an important initiative to improve
education in Indonesia. Realistic Mathematics Education (RME) can be used as an
approach to teach mathematics because students can feel welcome, since they
have a right to experience mathematics on a level they can understand and use
in daily life.
