ENHANCING STUDENT’S MATHEMATICAL COMMUNICATION ABILITY USING AUDITORY, INTELLECTUALLY, AND REPETITION MODEL IN EIGHT GRADE SMP NEGERI 2 PANAI TENGAH ACADEMIC YEAR 2015/2016

This research aims to: (1) enhance student’s mathematical communication
ability using Auditory Intellectually Repetition (AIR) model; (2) to describe learning
activity enhancement through AIR model.
This research is a classroom action research (CAR) consists of two cycles
with two meetings for each cycle. The subject is thirty students in grade VIII – 1 in
SMP Negeri 2 Panai Tengah Academic Year 2015/2016. The object of this research
is to enhance student’s mathematical communication ability on topic of Solid
Polyhedron using Auditory Intellectually Repetition (AIR).
Data come from preliminary test, mathematical communication ability test at
the end of each cycle and observation paper for each meeting. The preliminary test
reveals that 20 of 30 students (66.67%) passes the test and average scores in
preliminary test 64.58 is still low. At the end of cycle I using AIR model, it reveals
that 22 of 30 students (73.33%) passes the test. At the cycle II, 26 of 30 students
(86.67%) pass the test. It means that there is an enhancement of 13.34% from cycle I.
The enhancement of student’s mathematical communication ability shown by
Normalized Gain (g) is 0.50, in category Moderate and there is a difference between
average scores in Cycle I (71.88) and Cycle II (78.47) or there is an enhancement of
6.57 on their average score. At the same time, there is an enhancement on teacher’s
activity as provided through observation from 68% in Cycle I to 87% in Cycle II, in
category Good. An enhancement of student’s activity also occurs from 67% in Cycle
I to 86% in Cycle II, in category Good.
The conclusion is Auditory Intellectually Repetition (AIR) model enhances
mathematical communication ability of students in Grade 8 SMP Negeri 2 Panai
Tengah. It is strongly recommended that teacher should Auditory Intellectually
Repetition (AIR) as a learning activity alternative and always to create some
exercises and tests to enhance mathematical communication ability of students.
