Description
Summary:An ability needed by students in the 21st century to deal with an unexpected conditions. Mathematical literacy is one of an ability that students needed to face that situation. This study aims to measure the mathematical literacy ability of students in 1 Tempel Junior High School. This research uses quantitative survey methods. Random sampling will be done on all grade 7th students with total 63 students with high, medium, and low ability. Data collection done by a test that consist ten items about mathematical literacy on quantity content. The scoring model used in this study is the partial credit model (PCM). Data analysis that used here included construct validity, content validity, instrument reliability, items difficulty and estimation of student literacy abilities. Data analysis uses Quest software and Microsoft Excel 2010. The construct validity of the instrument proved valid, which was proven using EFA items difficulty and the content validity was 0.85. Test item reliability was 0.63 and the level of lies at an interval of -0.5 to 0.42. The result shows that the mathematics literacy ability of students on quantity content in the medium category is in the range of -1.77 to +0.33.
