Abstract

This research is motivated by the problem of students' mathematical representation
abilities in solving problems of arithmetic sequences and series in class XI IPS 4. Students are
less able to show geometric patterns in solving problems, do not use mathematical expressions
and are not confident in expressing their arguments. So this study aims to determine the ability
of students' mathematical representations in solving problems of arithmetic sequences and
series. This research is a type of qualitative descriptive research. Data were collected by
interview, documentation and test methods. This study used 2 interview subjects who were
representatives of 2 groups. Namely 1 subject in the FD (Field Dependence) group, 1 subject
in the FI (Field Independence) group. Interview subjects were randomly selected based on the
results from the GEFT test.
Keywords: mathematical representation, problem solving, sequences and series
