The results of observations on learning activities in class VIII F of SMP Negeri 2 Kediri showed that learning in class still uses the conventional system. As a result, students become passive and less enthusiastic in participating in mathematics lessons. The purpose of this study was to determine the increase in student activity and achievement after participating in learning with a contextual approach. This research is Classroom Action Research using a cycle system which is carried out in class VIII F students of SMP Negeri 2 Kediri for the 2022/2023 academic year. The instrument used to retrieve data about student learning activities and achievements comes from the question bank so that the quality only follows construct validity. Testing this instrument uses Rasch Modeling by looking at the MNSQ-ZSTD infit-outfit value, reliability, separation and dimensionality. The results showed an increase in activity and achievement in learning mathematics in class VIII F after implementing contextual learning. Based on data on student learning activities in cycle I, a score of 66.75 (active) was obtained and in cycle II it was 84.5 (active).
