INTRODUCTION

Orange Coast College (OCC) is a public 2-year institution 

located in Costa Mesa, California.The college is one of three colleges in the Coast Community College District and was founded in 1947.

Nature of the Problem

The problem is that according to Greene (2000), senior writer for the Chronicle of Higher Education, "empirical research still needs to be done to find out whether ethnomathematics draws students in" (p. A17).Utah State University elementary education professor Barta (personal communication, October 21, 2000) agrees that statistical evidence would certainly make a positive argument in favor of ethnomathematics as being instrumental in student success.

Purpose of the Study

The purpose of this study was to determine if students taking Intermediate Algebra who are taught with an ethnomathematical pedagogy at OCC perform better than those students taking Intermediate Algebra who are taught without an ethnomathematical pedagogy. 

Research Question

There was one research question for this study:"Do students who are taught with an ethnomathematical pedagogy at OCC perform significantly better in Intermediate Algebra than those students who are taught without an ethnomathematical pedagogy?"


Research Hypothesis

Students who are taught with an ethnomathematical pedagogy at OCC perform significantly better in Intermediate Algebra than those students who are taught without an ethnomathematical pedagogy.The independent variable is the use of an ethnomathematical pedagogy to teach Intermediate Algebra and the dependent variable is the final grade in Intermediate Algebra. 

A BRIEF SUMMARY OF THE LITERATURE

The investigation of the literature provided a theoretical foundation for this research.According to Fasheh (1997a), "a common misconception in the teaching of math has been, and still is, the belief that math can be taught effectively and meaningfully without relating it to culture or to the individual student" (p. 281).In relation to teaching mathematics from a non-traditional approach, Schultes and Shannon (1997, p. 231) found that many students have gained greater appreciation for mathematics after having learned the subject matter from a cultural perspective.This has contributed to students feeling more comfortable and confident about discussing mathematical concepts, such as infinity, with their peers (Schultes & Shannon, p. 231).

In relation to ethnomathematics and multicultural education, teaching is much more than the transferring of knowledge--teaching is a cultural activity that should induce the creation of knowledge (Freire, 1998, p. 49).


Multiculturalism as it relates to ethnomathematical pedagogy is about "listening to and learning from others who come from different experiences" (Henderson, 1996, p. 50).Finally, mathematics should not, according to Fasheh (1997b), be taught in isolation (p. 27).

METHODOLOGY AND PROCEDURES

A review of the literature on ethnomathematics and multicultural education was conducted.A quasi-experimental research methodology was used for this study.The population for this experimental research consisted of all students who have taken Intermediate Algebra at OCC.The sample for this experimental research consisted of students enrolled in two sections of Intermediate Algebra during the Fall 1996 and Fall 2000 semesters.

The sample was divided into two groups.Those students who completed Intermediate Algebra at OCC who were taught with an ethnomathematical pedagogy were placed in group A; those students who completed Intermediate Algebra who were taught without an ethnomathematical pedagogy were placed in group B.


The final grades were obtained from the semester final grades transmittal sheets completed by the researcher.The investigator taught both courses during the same time period, and used the same textbook, and examinations for Intermediate Algebra during the Fall 1996 and Fall 2000 semesters.These courses were identical in content and only differed in that they were taught during two distinct semesters.Students receiving withdrawal grades or audit grades were not included in the sample.The letter grade earned by each student was converted to the standard 4-point number system of A=4.0, B=3.0, C=2.0, D=1.0, and F=0.0.A grade of "credit," that is, "CR", was equivalent to 2.0 points.A grade of "no credit," that is, "NC", was equivalent to 0.0 points.The mean of each group was computed and the mean scores were compared using the t-test.

Data Analysis

Null Hypothesis

There is no statistical significant difference between the mean score in Intermediate Algebra of students who were taught with an ethnomathematical pedagogy at OCC and the mean score in Intermediate Algebra of students who were taught without an ethnomathematical pedagogy.

Alternative Hypothesis

Students who completed Intermediate Algebra who were taught with an ethnomathematical pedagogy at OCC will have a higher mean score in Intermediate Algebra than those students who completed the course and were taught without an ethnomathematical pedagogy.

Level of Significance

The level of significance used for this study was 0.05 with a one-tail rejection region.

Statistical Test


A one-tail t-test of hypothesis was used to test the means of independent samples.This statistical test was used because it was hypothesized that there was no statistical significant difference between the mean score of students who completed Intermediate Algebra who were taught by using an ethnomathematical pedagogy at OCC and the mean score in Intermediate Algebra of students who completed the course who were taught without an ethnomathematical pedagogy.

Assumptions

It was assumed that students who completed theIntermediate Algebra course during the Fall 1996 Semester were comparable in mathematical ability and preparation to the students who completed the Intermediate Algebra course during the

Fall 2000 semester at OCC.It was also assumed that the selection of the sample for this study was representative of the population of students of Intermediate Algebra at OCC.

Limitations

The results obtained in the study were specific to the Intermediate Algebra courses taught by the researcher at OCC during the Fall 1996 and Fall 2000 semesters.These results were limited to the field of mathematics, the Department of Mathematics, and the college.This limitation may be a threat to the external validity of the study in that the results of the findings relate to community college students in general and to students at OCC in particular.

RESULTS

The following Table records the statistics and t-test calculations that were obtained to compare the means of the grade point averages of two group of students who had completed Intermediate Algebra at OCC:(a) those students who were taught with an ethnomathematical pedagogy at OCC, and (b) those students who were taught without an ethnomathematical pedagogy at OCC.

Level of Significance = 0.05

Degrees of Freedom = 34

Critical t-value = 1.645

Calculated t-value = 1.850

Since the calculated t-value exceeds the critical t-value at the 0.05 level of significance, the null hypothesis was rejected and the alternative hypothesis was accepted.There was a

statistically significant difference between the mean scores in Intermediate Algebra for students who were taught with an ethnomathematical pedagogy at OCC and those students who were taught without an ethnomathematical pedagogy.

CONCLUSION

The null hypothesis was rejected since the calculated t-value of 1.850 exceeded the critical t-value of 1.645 at the 0.05 alpha level of significance.Thus, it was concluded that there was a statistical significant difference between mean scores in Intermediate Algebra for students who were taught with an ethnomathematical pedagogy at OCC and those students who were taught without an ethnomathematical pedagogy.
