Abstract

 

According to the founder of the field of ethnomathematics, Professor Emeritus Ubiratan D’Ambrosio,[1] the term “ethnomathematics” is used to express the relationship between culture and mathematics.  Ethnomathematics has been broken down into five sub-fields: non-western mathematics, mathematical anthropology, sociology of mathematics, vernacular mathematics, and indigenous mathematics.[2] While a large quantity of data exists that links mathematical understanding to the cultural context in which the student learns, there is a large debate as to whether an ethnomathematically designed curriculum would be feasible or practical for modern mathematics education.  This paper analyzes what the possible role of ethnomathematics is in modern education by focusing on the importance of culture in education with the research question: Should mathematics in schools be taught using an ethnomathematical approach and if so, is such an approach feasible?  By comparing and contrasting arguments both for and against ethnomathematics, this paper analyzes whether culture has an effect upon mathematical understanding, and, what significance ethnomathematics should have in school curriculum. Based on the results of the comparison, ethnomathematics is shown to be an applicable and possible part of modern mathematics education.

 

Background

Leigh Wood writes, “All cultures are mathematised, in that people within any culture use ideas of mathematics in their everyday life”.[3] According to research of ethnomathematicians such as Ubiratan D’Ambrosio, the cultural applications of mathematics are present in everyday life. He explains that when the word ethnomathematics is broken down, the prefix “ethno” refers to natural and socio-cultural environment. Ethnomathematicians strive to link the culturally diverse background of the student to the curriculum taught in the classroom.

Brazilian San Francisco State University professor and researcher Mariana Ferreira, did work with the Xingu tribe of the Amazon:

 

Ferreira: "You have one pen, and you obtain a second. How many pens do you now have?"

Indigenous woman: "I have one".
Ferreira: "How did you obtain this answer?"

Indigenous woman: "I have one pen, and I do not need the other". [4]

 

Based on an experience like the one above, numerous researchers of ethnomathematics cite how the cultural influence of the indigenous woman changed her outlook on what was meant to be an applied mathematics problem. The expected answer was “two” for the quantity of pens obtained. However, as can be ascertained from Ferreira’s work, the Xingu woman interpreted the question in a manner that reflected her needs and that of her fellow tribesmen. Situations such as this involving behavioral patterns call for an approach different than that of a normal classroom. Ethnomathematicians strive to find cultural links to promote deeper understanding of the mathematics of diverse peoples. The mathematics of cultures across the world varies not because of interpretation of numeric differences but because of cultural boundaries and methods of thinking. Rather than relying on pure mathematics, the Xingu woman’s answer reflected the ideologies that she had been taught. Ethnomathematics in an anthropological setting is used to understand cultures based upon their mathematical philosophies.

However, others such as Dr. Ron Eglash at Rensselaer Polytechnic Institute cite the more advanced mathematics that indigenous cultures have developed. In particular, Dr. Eglash expresses how ethnomathematics provides a new picture of the sophisticated mathematics of indigenous cultures that is often mistaken for primitivism. In African Fractals, Modern Computing and Indigenous Design, Dr. Eglash gives specific evidence to prove the existence of fractals in African culture within hairstyles, architecture, sculpting, metalworking, and other crafts.[5] By focusing on the advanced mathematics that already exists in cultures, ethnomathematicians can redefine what is often seen as pure primitivism. Instead, evidence exists that many non-western cultures have developed sophisticated mathematics that they require for the specific context of their living situation.

In order to expand the knowledge of students and teachers, much of the work currently being done in ethnomathematics is connected to ideas related to multicultural educational theory.  While ethnomathematicans propose the full integration of multicultural practices, many social realities often make such integration extremely difficult.[6]

            The late philosopher Paulo Freire described teaching and learning as a relationship in which both sides gain new knowledge.[7] The use of various algorithms for such basic mathematical concepts as division and multiplication draw attention to the need for more specialized education; with so many methods of working, many think it is important to ensure that the student is able to understand concepts from his or her own point of view. Because of ethnomathematics, a new mathematical definition has arisen: “Mathematics is a social product that originates from practical motivations” [8]

 

Investigation 1: Arguments Supporting Ethnomathematics in Education

           

1.1 A Cultural Perspective

Researchers in ethnomathematics express the need to teach mathematics in a culturally sensitive manner, basing methodologies on culture and surroundings rather than on traditional western mathematics. While most ethnomathematicians agree that it is impossible to build a curriculum based on ethnomathematics because of the simple fact that the cultural surroundings are what determine how material should be taught, it is agreed that a curriculum can be taught from a multicultural perspective.

 

1.2 Connections Between Culture and Mathematics

            Ubiratan D’Ambrosio argues that much of the mathematical curriculum in modern schools worldwide is so disconnected from a child’s reality that it is impossible for the child to be a full participant in it: “The mathematics in many classrooms has practically nothing to do with the world that the children are experiencing.”[9] Also, the content of many mathematics programs does little to help in preparing children for the modern world and leaves out important connections to technology. Instead, education serves as a filter, allowing or not allowing students to pass from one grade to another or entrance into advanced educational opportunities.

            Modern academic curriculum focuses on the use of mathematics without a focus on culture. It is a discipline without cultural significance or connections, designed to teach children. In most classrooms, children are expected to learn prescribed arithmetic procedures without necessarily gaining a deeper and conceptually significant understanding of what they are studying and without forming linkages between what they learn and the world around them.

Ethnomathematics bridges culture and math together, forming a connection between the surroundings of the child and the world of mathematics. By allowing the student to develop a personal understanding of why mathematics works, thereby forming connections, the student is then able to explain and comprehend his or her work on his or her own terms. In essence, the student personalizes the given mathematical information in order to develop a stronger understanding of the material, making it easier to remember and utilize by the way of connections to reality.

           

1.3 Algorithms Show Cultural Differences

Fundamental differences in algorithms, precise, systematic methods for solving a class of problems,[10] show the effect that culture has on how students do math problems. Professor Daniel C. Orey is the principal investigator and coordinator of the Algorithm Collection Project at California State University, Sacramento, a project that collects alternative algorithms in mathematical problem solving from all over the world.[11] Dr. Orey and other researchers found that by observing algorithms, it is possible to observe the innate differences in mathematics (arithmetic calculation) between various cultures.

For example, in the operation of division (see figures below), students from various parts of the world produced greatly differentiated algorithms for the same task. [12] Diverse algorithms still yielded the same mathematical answer, proving the point of many ethnomathematicians: there is more than one way to solve a problem. Different teaching methods are needed to cater to the individual thought process of the student.

Both students from Professor Orey’s sample attended Encina High School in Sacramento, California, but because they both originally immigrated to the United States (originating from Yugoslavia and Vietnam), they were taught to use alternative algorithms that reflected the pedagogy of their native countries. These algorithms differed from one another, but both came to the same answers at the end of the problem. The difference in the mathematics that each pupil showed was a direct consequence of the culture in which each student was brought up: using the principles of ethnomathematics, it is possible to realistically hypothesize that a single curriculum would be detrimental to both students; rather than expanding upon the knowledge that each student had already obtained, a set standard would force both students to regress backwards in their methods in order to learn new algorithms. The importance of curriculum designed to reflect culture is clear in situations involving algorithms, leading researchers to propose that students need a more personal, connected explanation of mathematical material in order to further successful learning of concepts.

 

1.4 Evidence in Favor of Ethnomathematics

            Much research has been done to show a correlation between culture and the ability of the student to perform mathematics. In a study, Dr. Eduardo Jesús Arismendi-Pardi of Orange Coast College has demonstrated that students in an Intermediate Algebra class taught using an ethnomathematical pedagogy outperformed students in a normal Intermediate Algebra class according to the mean score of the students’ final grades at the end of the semester.[13] Such studies have a level of ambiguity that gives room for criticism, but conditions in both classes were designed to be as similar as possible. While the instructor taught both classes, and the courses were similar and identical in content, he made a clear note that the results were specific to the Intermediate Algebra class and his students.

            However, in studies involving education, there is generally an unknown variable in that the group of students may have different learning abilities. In his study, Dr. Arismendi-Pardi stated the assumption that the students in both classes were comparable in mathematical abilities even though the first class (taught without ethnomathematics) was taught in Fall 1996 while the second (taught with ethnomathematics) was taught in Fall 2000. From an opposing standpoint, the results reached by the survey can be brought under question by the examining the fundamental differences between students four years apart and possible changes in the teaching style of Dr. Arismendi-Pardi. It is also possible that the quality of students at the college simply improved, bringing about higher final grades in the Intermediate Algebra course. More studies of this sort are needed to prove to skeptics that ethnomathematics can play a key role in improving the process of educating the student.   

            A similar example involves another study of Adrianna Magallanes’ at Torch Middle School, in which students trained with an ethnomathematics software were evaluated against a similar group of students taught only with traditional methods. The students using the software obtained higher scores, showing further evidence in support of ethnomathematics.[14]

 

Investigation 2: Arguments Against Ethnomathematics in Education

 

2.1 Fun and Games in the Classroom

Arguments against an integration of ethnomathematics into modern curriculum center around concerns that through specialized curriculum adapted to culture, using methodologies such as games and activities will result in the loss of academic achievement. John Leo views ethnomathematics as a rant about “eurocentrism,” claiming that with the focus on culture instead of pure curriculum, the knowledge of the student is impaired by the inclusion of too much cultural information.[15]

            Many of those opposed to ethnomathematics state a similar argument. Marianne Jennings cited her daughter’s textbook as being full of poetry, pictures, and lectures on the environment. She also cites that the book, designed for multicultural education, is 812 pages long as opposed to the average of 200 pages in an algebra textbook in Japan. The textbook under scrutiny contains its first equation on page 165.[16] This point illustrates the difficulty of designing a textbook and curriculum geared towards multicultural understanding. Critics such as Mrs. Jennings claim that because of ethnomathematics, the students will become lost in the cultural significance of the material. With such an overload of information, especially since a major goal of ethnomathematics is to bring connections between various fields of mathematics, the student is left unaware and uncertain as to basic laws and fundamentals of mathematics.

 

 

2.2 Cultural Misrepresentation

            A fatal flaw with ethnomathematics is that it relies upon “cultural diversity” as a teaching tool. The more multicultural the material becomes and the more diverse the audience that the teacher tries to appeal to, the greater the possibility that the mathematical lessons will be both more shallow and more superficial. While such exposure to diversity is meant to build connections between the material and the everyday life of the student, the curriculum is at risk of being lost in the process, leaving the student with at best, an unsatisfactory understanding of what is being taught. Ethnomathematics also precludes the single most important requirement for a successful education: coherent means to a discernible end.[17] In the era of standards and testing that have overcome most schools, these two points are a large concern for educators.

 

2.3 The Difficulty of Designing Curricula

            There are few if any textbooks published in English that teach mathematics from an ethnomathematical standpoint. Similarly, there are very few classes taught at universities designed towards multicultural mathematics for preparing teachers.[18] With this lack of direction, it is difficult for teachers interested in ethnomathematics to create a common curriculum. Also, due to the importance of appealing to the students’ needs and ethnic backgrounds, it is almost impossible to create a single curriculum for multiple classes. The sheer difficulty of engineering material designed specifically for individual students and assessment standards from multiple cultures places a large amount of stress on the teachers.

            Many educators are unfamiliar with the links between math and the surrounding world.[19] It appears from discussion related to ethnomath in the literature that there is a concern that many teachers simply do not have the time to research and employ strategies aimed at aiding all ethnicities of students in their classrooms.

            Ethnomathematics also preaches a de-emphasis on the authority of teachers.[20] Rather than “teaching to” the students, the learning process becomes more of a “teaching with” the interaction and help of the students. Ethnomathematics requires teachers to learn more about their students before they can properly teach the curriculum, meaning that teachers would be forced to throw away the established shield of formality in order to help their students to understand mathematics on a new, more familiar level.

            Many students have been taught to stay quiet and do not formulate questions in class.[21] The inclusive curriculum that is demanded by ethnomathematics only works when both the teachers and students work together to further education. If students are passive or fail to cooperate, it becomes seemingly impossible to teach them using this system. And often, cultural differences can lead students to refuse to work together, resulting in an unfriendly situation from what was meant to be an inclusive and good-willed system. Students may also have difficulty in comprehending curriculum designed for multiple groups. Being assaulted by multiple subjects at once instead of pure mathematics may confuse some students, resulting in a greatly stunted rate of learning.[22]

            Much of the activities published in English used in multicultural mathematics and ethnomathematics have been designed for younger children, showing them as simple and folkloristic introductions to “real” mathematics.[23]  This assumption has the possibility of making students uneasy towards such a curriculum. In order for a system based on ethnomathematics to work in the classroom, there needs to be a unifying and more expansive component that works beyond what currently exists.[24]

           

2.4 The Multicultural Mathematics Dilemma

          Ethnomathematics is meant to succeed where previous multicultural mathematics education has failed. The idea of connecting mathematics to cultural heritage invites examples which replace class characters such as Dick and Jane counting marbles with Tatuk and Esteban counting coconuts.[25] Changing curriculum to reflect culture in such a superficial manner only serves to reinforce views on primitivism. For ethnomathematics to work, it needs to focus more on the math that is suitable to the particular context of the classroom. Building on mathematics that has already been taught to children in the context of everyday life may be beneficial to students, while forcing them to learn ancient Egyptian math may have a detrimental effect. Picking and choosing what and how students should be taught is a difficult process that, while well-meaning, runs the risk of leaving many students behind.

            In individual cases, it is possible that some students may not do well with a curriculum focused around ethnomathematics. Conversely, some may not do well without it. In order to improve mathematics education, the solution cannot be to simply choose which group should lose out on increased understanding.

Conclusion

        When examining the pros and cons of mathematics education, it becomes clear that ethnomathematics, while well meaning, is not the panacea that can remedy any and all faltering that present day mathematics education is experiencing. Multicultural education has failed in the past by unintentionally emphasizing the false notion that mathematics from indigenous cultures is at most primitive, especially when examples focus only on lower primary school levels.[26] However, ethnomathematics seeks to redeem multicultural education in the classroom by focusing on the appropriate material for the context of the math class rather than simplifying culture.

            There was also a greater amount of data supporting ethnomathematics than against it, with studies such as that of Dr. Arismendi-Pardi demonstrating how the majority of students tested, with exceptions appearing amongst individuals, appear to consistently learn better with curriculum focused on bridging culture and mathematics. Many of the arguments against ethnomathematical education seem short-sighted, if not premature, focusing on the present difficulty of converting curriculum rather than focusing on the benefits that could be achieved in the long run. An approach towards teaching through ethnomathematics has the possibility of revolutionizing mathematics education in schools, even if such an approach may be difficult.
