Definition of Modelling inMathematics
Mathematical modeling is a process of
structuring the extra-mathematical(from the real world) to decide suitablemathematics content, to working
mathematically within mathematics.

Modelling in Lower SecondarySchool
Most primary and lower secondarystudents are difficult to motivate:
Mathematical Concepts Methods
Techniques
Terminology Results

Modelling in Lower SecondarySchool
Unless:
Clear references to the use ofmathematics
Relevance of mathematics to extra-
mathematical context and situation(Real World Mathematics)
(Galbraith, n.d)

Real World Mathematics
According to Blum (1993),
Realistic Mathematics means that theproblem situations should beexperientially real for student, from out
side of mathematics.

Why Real World?
basically in the use of mathematics youhave to formulate problems fromoutside of maths as well as solving themafter you succeeded in formulatingthem (Pollak, n.d: 111)
realistic teaching is an appropriate
method for quantitative literacytraining (Steen, 1998,2001; Alsina, n.d).

Everything that has to do with
Nature
Society
Culture

Including:
Everyday life as well as school anduniversity subjects or
Scientific and Scholarly disciplinesdifferent from mathematics.
(discussion document of ICMI Study;Alsina, n.d)

All of these because:
Students will appreciate their creativityor discover their limitations.

Mathematical Modelling - The Real
World Approach
Contribute giving more meaning to the
teaching and learning mathematics.
Helps learners to understand the lesson.
Helps learners to understand how models in
mathematics are invented.

We as a teacher should know:
Why we teach the lessons Do we believe what we have said? Are the results practical, and are the answers
reasonable? Encourage students to be able to construct theirown ideaDont say: What is the solution for this problem? or Prove
itHowever Here is the situation, can you figure out what is
going on?

How to teach the students inrealistic math modelling?
According to Griffin (2011), there are four methodsof teaching real world mathematical modelling:
Suggest several examples of how mathematics skillscan be used in the real world. (For instance, countingmoney and calculating bank account)
Use daily materials and objects to prove equations
and formulas. (For instance, devise a lesson ofgeometry to find the formula of the volume of a cube,by giving them real object of a cube and placesomething inside)

How to teach the students inrealistic math modelling?
Take the class outdoors to illustrate conceptsin their books. (For instance, bring our studentsoutside the classroom to measure the height ofa tree by using its shadow)
Start and end the lesson by reviewing the basicterms of the lesson and relating it to the
equations and concepts with the activity.Read more: How to Teach Students About Math in the Real World |eHow.com http://www.ehow.com/how_7771004_teach-students-math-real-world.html#ixzz1CMyiSOB9

Issues of Real WorldMathematical Modelling in
Indonesian Context
Lack of using real world materials Students are not interested in constructing
their own ideas
Lack of evaluation of research (designresearch) for realistic mathematics

Suggestion
According to Mousoulides (n.d), in attempt toprovide a coherent framework formathematical modelling at school level isorganized into three strands:
Situates a mathematical modelling as a problemsolving activity
Discusses modelling activities, by presentingthe principles for designing and implementingmodelling activities in classroom
Contextual nature and assessment ofmathematical modelling.

Opportunities in Modelling
Lead to the development of students'application-oriented learning
Help students to understand and tocope with the real world
Provide rich opportunities for studentsto develop their ideas
Help teachers to develop anunderstanding of students thinking.

Problems in Modelling
Instruction and assessment (required alot of time)
Students Point of View (math lessonsand examinations more demanding)
Teachers Point of View (Teaching moredemanding)
