Communication is the way of delivering messages with the aim
of order that the message to be submitted can be understood. In learning mathematics, students are required to
have good and clear communication skills. This
research is descriptive research using a qualitative approach that aims to
describe the mathematical communication profile of junior high school students
in solving mathematical task in terms of self efficacy. The instrument used is
questionnaire self efficacy, mathematical ability test, mathematical
communication test, and interview. Subjects in this research are one student
with high self efficacy and one student with low self efficacy. The results
showed that student with high self efficacy have the following mathematical
communication as follows: 1) Accurate, complete, and fluent in write down the
things that are known and asked. 2) Accurate, complete, and fluent in write
down the statement in the task into math models. 3) Accurate, complete, and
fluent in write down ideas, situations or mathematical relations in
mathematical task given. 4) Accurate, incomplete, and fluent in write down
mathematical task solving steps towards the final solution mathematically. 5) Accurate,
complete, and fluent in write down the reasons related to mathematical
solutions in the original context. While student with low self efficacy have
the following mathematical communication as follows: 1) Accurate, incomplete,
and fluent in write down the things that are known and asked. 2) Accurate,
complete, and fluent in write down the statement in the task into math models.
3) Accurate, complete, and fluent in write down ideas, situations or
mathematical relations in mathematical task given. 4) Accurate, incomplete, and
influent in write down mathematical task solving steps towards the final
solution mathematically. 5) Accurate, complete, and fluent in write down the
reasons related to mathematical solutions in the original context. This
research provides an overview that self efficacy owned students influence the
mathematical communication in solving mathematical task.
