AN ANALYSIS OF DIFFICULTIES ON MATHEMATICAL MODELudINTERPRETATION OF JUNIOR HIGH SCHOOL STUDENTS ON THE MATERIALSudOF TWO-VARIABLE LINEAR EQUATION SYSTEM

摘要

Modeling is one of abilities included in studying mathematical materials. Modeling udis mostly used to express the events of everyday life , such as modeling of tsunamiudwave, modeling of population growth, and modeling of economics growth. udTherefore, mathematical modeling is an important ability to be possessed byudstudents. It is in line with the opinion of Niss (2010) who states that Modeling is audCrucial Aspect of Students' Mathematical Modeling. Considering its significance, udmathematical modeling should be learned by students since they attend elementaryudschool. For example, Singapore school curriculum has provided an opportunity for udstudents to learn mathematical modeling abilities since they attended elementaryudschool (Kaur and Dindyal, 2010). On the other hand, it is a fact that students - inudsome countries, such as Germany, England, Romania, Canada, Czech Republic, udMozambique, Netherlands, and Japan - have difficulties in mathematical modelingud(Ikeda, 2007). Therefore, this paper is intended to discusse some difficulties faced udby junior high school student in conducting mathematical modeling and model udinterpretation, particularly in the materials of linear equation system of two udvariables. Data were obtained from students in two junior high schools coming fromudtwo and three cluster schools in the Bandung Municipality, covering research subjectudas many as 151 students.
