Realistic Mathematics emphasizes the construction of the context of
concrete objects as a starting point for students to acquire mathematical
concepts. Concrete objects and environment objects can be used as a
context for learning mathematics in building mathematical connections
through social interaction. Concrete objects manipulated by the student
within the framework of efforts to support students in the process
mathematics concrete to the abstract. Students should be given opportunities
to construct and produce mathematics in a manner and language of their own.
Necessary activities so that the reflection of social activity can occur
integration and strengthening of relations between subjects in understanding
the structure of mathematics.
Reflecting the above activities in learning the Numbers Fractions through
PMRI presumably can be concluded:
Student:
1. Students should be given opportunities to explore and reflect on
alternative concepts about ideas that affect learning fractions later.
2. Students should be given opportunities to explore and acquire new
knowledge about fractions by establishing that knowledge to himself.
3. Students should be given opportunities to acquire knowledge as a
process of change that includes the addition, creation, modification,
refinement, and rejection realignment.
4. Students should be given opportunities to acquire new knowledge of
fractions built by students for itself derived from a set of diverse
experiences.
5. Students should be given opportunities to understand, and implement
work fractions.
Teachers need to revitalize itself so that:
1. Sate himself as a facilitator
2. Able to develop an interactive learning
3. Being able to provide the opportunity for students to be active.
4. Able to develop curriculum and syllabus and curriculum actively
associate with the real world, both physically and socially.
5. Able to develop learning scenarios:
a. Interaction scheme: Classical, Group Discussion,
Individual Activities
b. Scheme Achieving Competency: Motivation, Attitude, Knowledge,
Skill, and Experience
