Proceeding of International Conference On Research, Implementation And Education Of Mathematics And Sciences 2014, Yogyakarta State University, 18-20 May 2014 ME-179 ANALYZING MATHEMATICAL LITERACY OF JUNIOR HIGH SCHOOL STUDENTS IN WEST SUMATRA Ahmad Fauzan State University of Padang ahmad_fz@yahoo.com Abstract The aim of the research was to describe mathematical literacy of junior high school students in West Sumatra Indonesia. The description was focused on the competences clusters mentioned by Program for International Student Assessment (PISA), namely reproduction, connection, and reflection cluster. Based on the description, it was analyzed the factors that have influenced mathematical literacy of the students. The method used in the research was a mixing method (descriptive and qualitative). Data was collected from 188 Junior High School students who participated in Mathematical Literacy contest in West Sumatra. The results of the research show that most students only master reproduction cluster and very few of them that master reflection cluster. For each cluster, the score of most students are very low. In addition, mathematical abilities of the students are not satisfactory. Key words: mathematical literacy, mathematical ability INTRODUCTION The achievements of the students of junior high school in learning mathematics, especially in the national examination, have been quite satisfactory. However, many educators do not satisfy with these results. The high achievements have not been reflected by the way students think and act in everyday life. The results were also not reflecting what the students normally achieved in daily quizzes given by their mathematics teachers (see Fauzan, 2010). Students' understanding of mathematical concepts tends to be temporary. They often forget the basic concepts that have been studied before, when such concepts needed back on the next topic. In fact, it is often found that junior high school students do not understand the basic concepts of fractions and integers they have learned several times in the elementary school (Fauzan, 2009). Another problem can be seen from the weakness of students in problem solving and reasoning, especially those involving higher order thinking. This can be observed from the results of some of the international studies such as the Trends in International of Mathematics and Science Studies (TIMSS) (see http://nces.ed.gov/timss/). As the TIMSS assessment framework focused on problem solving and mathematical reasoning, we can conclude that most Indonesian students are weak in both aspects of the mathematical abilities. Similar results were found in Program for International Student Assessment (PISA) studies (see OECD, 2010a; OECD, 2013). The rank of Indonesian students in these studies has always been at the bottom 10%, and there was no Indonesian students that could achieve the score at the highest two levels (see Stacey, 2011). The results achieved by Indonesia were far below the average score of the counties of Organization for Economic Co-operation and Development (OECD), as shown in Table 1. These conditions reflect that Indonesian students ME - 25
