Mathematical Representation of Students in Solving Linear Program Problems

The purpose of this study is to describe mathematics representation of vocational high school students insolving linear program problem. The representation that will be seen is pictorial representation, symbolicrepresentation and verbal representation of students with varying abilities. The research subjects were 3students of class XII from one of the Vocational High Schools in Jambi with a variety of high, mediumand low ability levels. The data was collected by giving two linear program problems that the studentswould work on, then conducting interviews based on each student's answer sheet to strengthen the testresult data. Answer sheet data and interview results were analyzed and presented in narrative text.Students with high abilities implement the three forms of representation accurately and are able to changethe form of one representation to another representation. Students with moderate abilities do notimplement pictorial representation and symbolic representation accurately. Low ability students do notimplement pictorial representation in problem solving
