The teachers' mathematics literacy ability for solving uncertainty problems on a PISA adaptation test

Abstract

In research related to PISA, students have earned many portions as research subjects. However, research on teachers is rarely conducted. It is widely believed that there is a link between students' ability and teachers' ability. This study aimed at describing teacher's solution on PISA adaptation test. The PISA adaptation test consists of 13 questions from 4 scopes. However, this research focuses on the scope of uncertainty consisting of 3 test questions. In this study, the subjects were 7 teachers who were randomly selected from a Junior High School. This study adopted Cobb and Koeno's model of design research. The finding showed that all teachers responded correctly in the scope of uncertainty at level 2 and level 4. Moreover, the results revealed that 42,86% of teachers achieved level 5 and 28,57% teachers achieved level 6. Therefore, to improve the quality of students it is necessary to improve the quality of teachers.
