Nusantara's cultural diversity is the identity of a nation, especially Indonesia. This inspired the lecturers of the Primary School Teacher Education (PGSD) Department of University of Muhammadiyah Malang who is Dyah Worowirowirastri Ekowati, Dian Ika Kusumaningtyas, and Nawang Sulistrani to write the Ethnomatika book.
Dyah explained that Ethnomatika came from a combination of two words which was Ethnic or cultural and Mathematics. Literally, it can be interpreted as learning mathematics by using culture as its medium. "So it's not just learning, but they can also get to know the culture of Nusantara through mathematics," She said.
Continued by Dyah, Ethnomatika was first introduced by D'Ambrosio, a Brazilian mathematician in 1977. But on his journey experienced development and began to be widely known in various parts of the world. Because his learning is more effective and simple through the media around students.
"Learning mathematics, especially for elementary school children must be taught something concrete. So you can't just explain the material and give questions. Because in Mathematics, there is a program called Realistic Mathematics. Using realistic objects that are around, like through culture," she explained.
In the game Engklek, for example, indirectly students also learn Mathematics when passing a plot that had been given a number and calculates the number of numbers passed. Next, made a traditional house which consists of any flat building and made a group consisting of triangles, and others.
Then, continued Dyah, through the Engklek game, students were also invited to play by making traditional houses based on groups that had been divided. Then students were welcome to mix and match between groups so that made a traditional house from the flat buildings.
The application of this book had been carried out in research and service in schools. "This is part of the development program of the Directorate of Research and Community Service (DPPM) in making books intended for lecturers. It is born in 2017 and for the subsequent printing process is this year," She explained.
Through this method, first, Mathematics became more realistic. Second, ethno learning (through observation) was a vehicle for learning while playing and outdoor learning for students. Third, it introduced culture to students. "That way, they are expected to have a concern to preserve it," she said.
"The last of course encourages students to continue to be grateful for God's enjoyment of things around us. This value is in accordance with the character values in the 2013 curriculum. That is the superiority of Ethnomatika based learning that we have worked for this book," she continued when interviewed on Thursday (4/18) afternoon in her room.
"Learning Mathematics is not abstract but can be applied in real life. Because for me, learning Mathematics is not just talking about formulas. More than that, Mathematics is an activity and language in everyday life, "concluded the woman who is also a lecturer at the PGSD Department UMM. (Win)
