Reflection
of Ethno Mathematics on 6th March 2013
We learned
about ethnomathematics with Prof Marsigit. He given
us everything that we didn’t know before. In this day, he created
quiz which could make us known about everything and known about this
world. He said that mathematics is a language. He said that because
he had a reference. People who said that mathematics is a language
were Wittgenstein. And then, Prof Marsigit also said about 4
dimensions of communication. And that parts of communication had to
arrange and didn’t random. Or we could that they were sequence. The
first level was material, second was formal and the third was
normative. The highest of that sequence was spiritual. Spiritual
communication was on the peak of grade in communication. If we could
use this last one, we could reach the highest level of the life.
And then,
we knew about new thing. It was the direction of knowledge. There
were two direction of knowledge. It weren’t horizontal and
vertical, but up and down. Prof Marsigit said knowledge that we had
learned also could reach in peak or went straight to the bottom. We
should always upgrade every inch of ourselves everyday and every
time, although our age would influence our capacity.
Mathematics
was not only in this era. We could find mathematics long long time
ago. How to prove it? If we had time machine we could go to past
time. Nevertheless, we couldn’t create time machine right now. The
only way was searching inheritance of people in last time. Prof
Marsigit said that the product of
mathematician in last time was the artefact. We could it in the
museum that shown the inheritance of mathematician last time. In
Java, Aijsaka was the first king that introduced us about a Javanese
language and in that language also there were Javanese numbers.
Numbers of Javanese there were twenty, no more or
no less.
From
Javanese culture we also could learn about mathematics. The day of
Javanese there were Legi, Pahing, Pon, Wage and Kliwon. When there
was an event, Javanese people always used that day to count when the
event would be done. They didn’t release that they had used
characteristic of mathematics. They used permutation to decide the
day of an event. It showed us that mathematics developed in the small
place or in the village and also primitive peoples.
There were
three dimensions of interaction. They were individual, small group
discussion and the last was the whole group discussion. The
individual interaction was about our self. The small discussion was
about one people with the other people but in the small part. The
example of small discussion was between students with a teacher in
the classroom. For the last was whole group discussion, we could say
that the classroom which included students and their teacher was the
example of whole group discussion. The whole group discussion could
increase confident of each student in that class if they were active.
