DEVELOPMENT OF INTERACTIVE COMICS BASED ON REALISTIC MATHEMATICS APPROACH TO IMPROVE MATHEMATICAL COMMUNICATION ABILITIES OF STUDENTS OF SMPS MUSDA PERBAUNGAN

This research aims to: (1) Knowing the validity of the interactive comics
based on realistic mathematics approach to improve mathematical communication
abilities of students of SMPS Musda Perbaungan. (2) Finding out the
improvement of students' mathematical communication by using interactive
comics based on realistic mathematics approach students of SMPS Musda
Perbaungan. (3) Knowing the practicality of the interactive comics based on
realistic mathematics approach to improve mathematical communication abilities
of students of SMPS Musda Perbaungan. (4) Knowing the effective of the
interactive comics based on realistic mathematics approach to improve
mathematical communication abilities of students of SMPS Musda Perbaungan.
This research is development research that refers to the 4-D development model
(define, design, develop, disseminate) which has been modified to 3-D. The
research sample was the seventh grade students of SMPS Musda Perbaungan,
Serdang Bedagai. The research instruments used were interactive comics, tests to
measure validity, tests of students' mathematical communication abilities, and
student response questionnaires. The results showed that: (1) Interactive Comics
that have been developed meet the validity with an average of 3.615 and obtain a
valid category, (2) In terms of practicality, the percentage of student response
questionnaires to interactive comics developed with the Realistic Mathematics
Approach is 94.5% with a practical (positive) category and the percentage of
teacher response questionnaires is 88.125% with a practical (positive) category (4)
Interactive comics developed have also met the effectiveness criteria with
individual completeness of 88.58 and classical completeness of student learning
of 86.79% with average of gain result is 0.726940 with high category. Overall, the
result of the research was found to be an effective interactive comic in teaching
and learning activities to improve students' mathematical communication ability
