Implementation of ethnomathematics based mathematics module to improve process skills

Abstract

Abstract.The study was conducted to examine the effect of using ethnomathematics-based mathematics modules from the results of exploring Adi Purwo's batik patterns. This study uses a Quasi Experiment research design. The procedure of this study used a descriptive method with pre-experimental research design in the form of "one group pretest-posttest" in which one class was treated using learning modules based on ethnomathematics based mathematics after which a description of process skills was carried out. The results showed the students' process skills improved after seeing the results of the pre-test and post-test. Then the results of the Gain test on the pre-test and post-test showed a score of 0.73 so that the use of the module was quite effective. Tests using the t-test against the score of the pre-test results with the post-test score of 21 students. Based on the calculation results it is known that the obtained t count of 29.54 and the significance value of 0.05 so that it can be concluded that the students' process skills in solving mathematical problems in the use of ethnomathematics-based mathematical modules are better than classes using conventional learning.
