INFLUENCE OF APPLICATION MODEL COOPERATIVE
LEARNING BASED MIND MAP ON MATHEMATICAL
COMMUNICATION SKILLS ON THE SUBJECTS OF
DERIVATIVES IN CLASS XI MUHAMMADIYAH KEDAWUNG
CIREBON
Based on the observations, according to the teachers of mathematics courses is
concerned, mathematical communication skills are still relatively low. It is seen from the
difficulty of students to convey mathematical ideas in the form of mathematical symbols, still
can not declare a daily occurrence in the language of mathematical symbols and there is a
mathematics teacher who is focused only teaches mathematics as much as possible to
students, so that students are difficult to understand. Given the importance of communication
skills of mathematics, so it is developing a teaching model that is closely connected with
mathematical communication skills, among others, cooperative learning model based mind
map. Cooperative learning model based mind map is a way used by teachers in a series of
learning activities where students are formed in specific groups then students describe and
communicate the way of thinking is structured in accordance with the student's mind. So it is
assumed when applied cooperative learning model based mind map then able to improve
mathematical communication skills in students.
The purposes of this study were to: (1) Describe the students' response to cooperative
learning model based mind map, (2) Describe the mathematical communication skills by
applying cooperative learning model based mind map, (3) to analyze the effect of the
application of cooperative learning model based on the mind map mathematical
communication skills on the subject of derivatives.
Data collection techniques used in this study were questionnaires and tests. The
population is all students of class XI SMA Muhammadiyah kedawung Cirebon. The sample
used was a class XI IPA 1 with a sampling technique using cluster random sampling.
The data analysis technique processed by using SPSS version 20 for Windows. From the
analysis of data obtained by the positive response to the use of cooperative learning model
based mind map by 78.41% and the average value of mathematics communication ability of
students is about 77.11. After testing the hypothesis obtained that thitung (3287)> t table
(1,689), then Ho is rejected and Ha accepted, meaning that there are effects of the application
of cooperative learning model based mind map on mathematical communication skills. The
regression equation Y = 14 216 + 0802 X. regression coefficient of 0.802 states that each
additional (increased) the use of cooperative learning model based mind map will affect the
communication skills of mathematics at 0.802. Coefficient is positive, it means there is a
positive relationship between cooperative learning model based mind map on mathematical
communication skills. From the correlation coefficient of 0, 486 obtained by the index of
determination of 0.236, which means 23.6% mathematics communication ability is
determined by the use of cooperative learning model based mind map and the remaining
76.4% is influenced by other factors
