History of mathematics:


Researches about the history of development of human species (available till the date) suggest that mathematics has been developed initially as guided by the basic requirements for the survival; this includes food habits, climate, space and other natural factors. As mentioned by D’Ambrosio (2001), Homo Sapins have been considered as living on the earth about forty thousand years ago. Australopithecus known as preceding the Homo Sapins lived in or somewhere near today’s Tanzania 5 million years ago and spread all over the world. Due to the power of analyzing, comparing and communication of the knowledge with the experiential world, these species transformed themselves as influenced by the climate, availability of food, available space, growing population and other factors. As these species spread to different places, they encountered new environment, climate, food and spaces. To tackle with new challenges in life they constructed new ideas and techniques. They shared their ideas through symbols, pictures and other forms of languages. This socially accepted knowledge formed a culture which further reconstructed and shared generation to generation.

Study shows that Australopithecus used chiseled stone to clean animal carcasses, it would make possible to scrape the bone, and thus, not only make use of every piece of meet but also extract nutrients from the bone that would not be possible only with teeth. They had to develop this instrument because their most common food was meat of animals and birds. As the population increased, they encountered deficiency of food they had to invent eating plant body parts or the fruits and hence had to develop farming. Thus the need for survival and curiosity for knowing have influenced people for inventing mathematical ideas like counting, measurements, and other systems in mathematics. The culture and religions are the systems of knowledge that we share and accept as common knowledge.


Mathematics, Culture and Politics:


The construction of mathematical or ethnomathematical knowledge has been greatly affected by the political interests. About 2500 years ago (D’Ambrosio, 2001) Greeks and Romans expanded their domain eastward of Mediterranean capturing the thousand-year-old civilizations such as Persia, India. The conquerors destroyed or colonized (or claimed as their own) the knowledge system of the conquered people and imposed their own knowledge system to present themselves as superior. The conquerors not only imposed their system of knowledge but sometimes they tried to destroy the objects representing the original knowledge system or they were eliminated from the territory or punished to death. However, not only the conquered got influenced from the culture of conquerors but sometimes the invaders also got influenced from the local culture and reconstructed their knowledge system to fit the new environment. For example, the black Africans taken to America not only got influenced from the American culture but they brought African culture in U.S and the American ethno-culture got influenced from the culture of the slaves taken from Africa. This has occurred also in the British and other European colonizers. They have reformed their mathematical knowledge after they colonized India, China and other countries in Asia and Africa. But due to lack of acknowledgement of the source of influence the academic mathematics looks different than what practiced in different cultures.

Thus, ethnomathematics values cultural construction of knowledge than universalizing the knowledge. Saying this does not mean to indicate that we need to ignore the important inventions in mathematics; ethnomathematics encourages to research on ethnic groups, identify the mathematical ideas in practice and incorporate them to the curriculum and text books so that these knowledge help learners understand and become comfortable in applying the system of knowledge in their day to day life. Ethnomath does not try to displace the mathematical inventions made earlier in Europe and America but it tries to re-enforce the world of math with further researches of ethnic inventions. It works in widening the field of math. Its emphasis is onto “mathematics for all”. This is more valuable for the country like our which is full of diverse ethnic cultures.


Talking only about ‘western curriculum’ and ‘western occupation’ in our schools and academic institutions will be an injustice and an immature decision. As the issue of large and small culture aroused in the above discussion, it is necessary to define what is meant by large and small culture. Can the knowledge be evaluated with respect to the population? Can it be restricted within the boundaries? So, who is the owner of the knowledge? Is the professor or a researcher who collects knowledge from students or the field of research an inventor of the knowledge? Or the actual inventors of the knowledge are the farmers, carpenters, sailors or other people who actually observe and experience in their day to day life. This is to be made clear before we actually enter into acknowledging the knowledge. In many researches and history books we can read that the mathematical knowledge have been contributed by different cultures like Egyptians, Babylonians, Indians and so and so. But there arise questions, who were Egyptians? Does “Egyptian civilization” represent the people who actually involved in the invention of the mathematical knowledge? Does “Arabian culture” represent the inventors who might have been in a minority ethnic culture within the large boundary of Arab? Will it be fair that all the ethnic communities who contributed in knowledge invention called as the inventions of the Indians? Will it be a justice to the inventors who lived in ethnic minority within the covering of huge population ignored and called their works as the work of the well known cultures and civilizations? Indians invented Number system, where is (the ancient) India and what was its boundary? Which people represent India? Are all the ethnic communities bounded by the boarder lines of India represented by the so called Indian faces? Can we call the inventions of the people living in a remote corner of India in an ethnic minority as the inventors of the so-called Indian Mathematics? What about the people living in different adjacent territories of the Indian subcontinent?


Thus the above discussion arises more questions. Is it possible that the number system as said to be invented in India covers Nepal in the assumption of that historical time? That means is it possible that the number system be developed by a farmer or a shepherd in the remote part of Nepal? So it means we need to find the place in Nepal where, how and in what culture and profession the knowledge was constructed. It may be a Gurung, Rai, Tamang, Chepang, Tharu, Dalits or other Janjatis. So is there any reason to claim that upper casts and people with majority claim themselves as superior of knowledge? Thus, there may evolve innumerable possibilities, besides accepting others’ ideas as the universal truths people around the world need to unearth the history and live with high-esteem.

We really need to thank D’Ambrosio of Brazil who helped us and the people around the world to understand and free ourselves from the intellectual colonization of western and so-called developed cultures. This is the world where many scientists and researchers lost their lives for attempting to disprove or reject the knowledge (as the only truths) established by the western and other powers. History shows that the economic powers have always tried to suppress other’s knowledge in the name of humanity and civilization. There have been attacks to different civilizations for the treasure of knowledge, economically weak civilizations have been destroyed and the knowledge and their recognition swept away. So it can be imagined that there may be hidden powers indirectly working to stop the comrades of ethnomathematics from excavating the hidden realities.


Ethnomatheamtics and Future:
Now to discuss about how the program “ethnomathematics” may contribute to empower ethnic cultures and individuals, it is necessary to know the meaning of the term “ethnomathematics” and its purposes. The prefix ‘ethno’ from ethnography refers to the study of mathematics in relation to culture. According to the proponent D’Ambrosio the term “ethnomathematics” can be defined as the study of mathematics that takes into consideration the culture in which mathematics arises by understanding the reasoning and the mathematical systems that they use. Culture refers to a set of norms, beliefs and values that are common to a group of people who belong to the same ethnicity. The people share a language, a place, traditions, and ways of organizing, interpreting, conceptualizing and giving meaning to their physical and social world (Hammond, 2000).

The people living in different cultures invented different mathematical ideas while attempting to organize, systematize and improve their livelihood with the changing time and world. The raw ideas invented by members of a culture are shared within the periphery of the culture through the language and activities. They are tested and verified or further modified due to change in time and need. This clearly indicates the cultural construction of mathematical knowledge. The evidences of some ethnomathematical researches show that different cultures in different places practiced different forms of mathematical knowledge. However, the western occupation and domination so paralyzed the human life in the third world countries that people considered math as the collection of truths discovered by the power houses of the intelligence which resided in the western culture. It is evident that even in western culture mathematics has been defined in different ways but the so-called intellectuals try to formalize and universalize the definitions and its contents.

From the above arguments it is clear that mathematics is a cultural construct, this helps us to be confident that our culturally rich and diverse society is full of such hidden mathematical treasures which are yet to be uncovered. The externally designed curriculum and the mathematical knowledge imported in the form of text books have brain-washed our children who are the pillar of the future. The foreign structure and hidden interests of designers not only fade the interest of students in mathematical learning but also it helps to produce individuals with low self-esteem and with disrespect to own culture and land. Very poor pass rates in our examinations and failure of individuals produced from the academic institutions in market and work place shows the failure of foreign curriculum (Luitel, 2009). Thus, it is a very immediate requirement of our society, market and the interest of the country to incorporate the practices of different cultures into local and national curriculum. This will definitely help generate interest in learners towards mathematics as they see the application in their day to day life.

Incorporating the ideas and inventions of ethnic groups and people living in minority in the text books will help children understand the value of all the people living in the society. The clashes and dissatisfaction appearing in the recent days in our country and all around the globe suggests the immediate need of an environment where every individual is respected for his/her own culture and given opportunity to enjoy and preserve her/his own identity. This will help establish democratic feelings in the minds of new generation. Ultimately this will help developing a democratic, prosperous, class-free and clash-free society. At the end, as the curriculum focuses on local need and planning for future it will definitely trace a smooth path for the future.

My Exploration of Culturally Embedded Mathematics


My Exploration of Culturally Embedded Mathematics



Amrit Bahadur Poudel
M.Ed Mathematics
Kathmandu University

While I was in high school, the image of mathematics was a subject of discoveries of the brilliant people around the world. Learning mathematics was to learn to take the challenges. I had no idea about the purpose of studying mathematics in school. Another motivating factor was that it is a subject which is compulsory to most of the good streams of studies. My teacher never told us that mathematics is a social and culture product. How people use mathematics and how it help people in their public life was not of any concern for me. I never imagined that the people around me in my village are also the inventors and the ones using the mathematical knowledge.

After taking the classes in the master’s degree in Kathmandu University, I came to know that mathematics is not a culture free subject. I still remember the moments of discussions in the class about the contextualization in curriculum. I was shocked with the wrong belief about the concepts and understanding in math I had.
Contextualizing a curriculum is a big issue. There is no exact measurement to measure the level of contextualization. As I learnt from the M.Ed classes, contextualization is a process of adapting the concepts of math in relation to the social and cultural values of the places where the learners live. This helps the learners to understand the value of learning math and find an appropriate use of mathematical ideas in their immediate life.

In the present context, the curriculum of our country is centrally prepared and has an imposed notion of teaching. The interest of the Nepalese students and their level of understanding, culture and social norms are not duly considered. Students in Jumla are expected to understand and solve the problems of electricity and taxes and service charges without any additional support in an equal proportion to the students of urban area. Even the students of urban area have knowledge of high level calculation but are confused when given simple problems of daily shopping and banking transactions. Thus the present curriculum and the textbooks are not fulfilling the present need of our nation.

Thus our curriculum and the teaching strategies are in a transition phase to be changed. In such a situation I have got the opportunity to involve in the "Developing culturally contextualized Mathematics Resource Materials: Capturing Practices of Woman and Disadvantaged Comminutes”. I have been guided to explore the cultural, social and individual activities through ethnographical research methods. I have been encouraged to search for various cultural, social and individual practices and pedagogical implications of a culture sensitive curriculum. To develop a culture sensitive curriculum, we observed the every day activities of the stakeholders such as students, parents, teachers and school management committee members.

In Taukhel, I tried to observe the mathematical implications in the local community. It was not so easy like collecting the stones out of the grains of rice to collect the mathematical applications in the local community like this where I never had been before and never had such research experience besides studying the philosophy of math in text books and in the class. The evidences were not readymade so that I could ask the people and dig the place where the objects were hidden. It was like diving into an Ocean to discover a pearl. Even I knew that the people were not ready to try to explain their practices because it was difficult for them to define their day to day works into a formula. Though they used different mathematical concepts invented by themselves and their ancestors, they had no idea what exact pattern or system they have been using. Even they had difficulty to recall the day to day activities and other social norms where they use certain mathematical rules and patterns. Since they used their knowledge instantly whenever they required, they never kept any account of the knowledge they used in their life. They didn’t have any system of collecting important skills or formulas they frequently required, their mind worked as the dictionary of everything. So I needed to plan and study their way of life and social and cultural reality before I actually could start my research.

For this, I chose one girl-student, her parents, her teacher and one of the women from the school management committee. My respondent student (Sarita) found mathematics very tough subject among the subjects she studied in her school. Math has always been her headache in her studies. Though she wanted and tried to be good in math, it has been a most difficult job to accomplish in her life. However as I observed her activities at home I found her using many mathematical concepts carefully and successfully without actually knowing the formula or any formal definition. She could make appropriate proportion of salt while she cooked the food for her guests. This demonstrated that she had a good idea of proportion. If her teacher would have given the examples of making appropriate proportion of salt or such other examples which occur in student’s day to day life while teaching Proportions, it would have bee very useful for students to understand the concept of Proportion.

She used a circular stone when she played with her friends; they played a game called chatti with one leg. She made different rectangular partitions of a big rectangle where she can stand and jump from one room to another. While she played, she jumped over alternate rectangles with one leg and sometimes she jumped over two rectangles. Her friends understood the rules of the game and the shapes of the geometrical figures for their game but not for their math in the school. They never wrote the rules in a formal format but they conveyed to each other whenever they gathered to play. They sometimes changed the patterns and made new rules according to their comfort or according to the number of members. Thus they had good idea about the patterns and geometrical figures but they never connected the activities while they studied the same patterns in the school.

Sarita and her mother normally kept the glasses of tea in a fixed pattern whenever they cleaned the glasses. They could exactly manage to place all the glasses on a small row of a rack which at the beginning was difficult for me to understand. They were very much used to with the sequence; I must say that the sequence they used in their home was purely invented by them. She easily understood the sequence she used while she arranged the glasses at home but I guess she will possibly fail in the test of the “sequence and series” chapter if she studied Additional mathematics in grade ten. There were lots of patterns and mathematical ideas the people used in their day to day life. It was a moment of joy when I found that the simple people with simple life in poverty in the remote corner of the earth use such interesting mathematical ideas. I enjoyed my journey and will be my pleasure to meet the people again and discover the inventions of the mathematicians living in the economically poor part of Nepal with the simple instruments of iron and wood in their hands and beautiful ladies with the with eye catching bamboo nets on their back. I remember the days in the following ways:



Oh! Beautiful lady,
You didn’t use any paste,
But your smiles with silver line of teeth,
gave a memorable taste.

Oh! Beautiful lady,
You don’t care what the hell mathematics is,
But I remember the math in your steps,
when you danced in the cool breeze.

Oh! Beautiful lady,
I am so sorry,
I enclosed all the beautiful patterns you made without the protractor,
But, but,
I am so sorry,
I forgot to take a single snap of the inventor.

Oh! Beautiful lady,
You are making me crazy.
