Peningkatan Kemampuan Literasi Matematis Peserta Didik SMP melalui Pembelajaran Inquiry Co-Operation Model pada Materi Statistika

Mathematical literacy skills are important for students to face challenges and opportunities in a complex and competitive global era. Based on the results of the PISA report and previous research reveals that the mathematical literacy skills of students in Indonesia are still relatively low. This study aims to determine the improvement of mathematical literacy skills of junior high school students through Inquiry Co-Operation Model learning on Statistics material. This research is a quantitative research with quasi experiment research method. The research design used is non-equivalent control group design. The population in this study were all grade VIII students in one of the public junior high schools in West Bandung Regency in the 2023/2024 school year and the sampling technique used was purposive sampling, two classes were taken which were used as experimental and control classes, each class consisting of 29 students. The instruments used are test instruments in the form of mathematical literacy ability questions and non-test questions in the form of student response questionnaires. After analyzing the test and non-test data, it was concluded that: 1) students with low initial ability were able to answer level 1 (20%) and level 2 (75%) questions, students with moderate initial ability were able to answer level 1 (60.86%), level 2 (69.86%), level 3 (26.08%), and level 4 (52.17%), and students with high initial ability were able to answer level 1 (50%), level 2 (100%) and level 4 (50%); 2) The increase in mathematical literacy skills of students who receive Inquiry Co-Operation Model learning is higher significantly compared to students who receive direct learning; and 3) Students' responses to learning the Inquiry Co-Operation Model as a whole are in the positive category. Therefore, the Inquiry Co-Operation Model can be applied in mathematics learning as an effort to improve students' mathematical literacy skills.
