Abstract:
The quality of environment has been declining and the destruction of environment can be found in
many places. Therefore, it is time for the society to embrace the awareness to protect the
environment, which can be reflected in the environmental-friendly behaviour. Implementing the
intervention that can increase the environmental-friendly behaviour is a challenge, however such
intervention can be initiated from the community at school. One of the initative that can be done is
to implement a contextual mathematics teaching that relates to environmental issues and aims to
educate students about the importance of protecting the environment that are needed to build a
sustainable society. A simple research was conducted to the seventh grade students of Santa Maria
Junior High School Pekanbaru. This study applied descriptive qualitative techniques with
contextual approach to learning, reflection, and commitment. The study starts by giving a set of
questions to the students. The questions given to the students were related to environmental
problems which were familiar to students. Then, the results of students‘ works were analysed to
gain understanding. Finally, students were facilitated to reflect on their learning and how they were
going to commit on protecting the environment. Data analysis were conducted by comparing the
results of the groups‘ work and from interviews of the reflection and commitment of the students.
The result shows that through the models that were given to them, students could solve the
problems and understand the efforts for protection, preservation, and usage of the environment for
sustainability of the environment. From the commitment of the students in general stated that the
students were ready to commit to increase their environmental-friendly behaviour.
