Abstract

AbstractThis study ass to describe the effectrvencss of students in solving logic problems ia terms of the mathematical communication skills of students in class X1 of SMA Swadaya in Academic Year  2020 / 2021 . the subjek of the study  are 14 student  of class X1 of private High School in Academic Year 2020/2021.The instrument in this research are 3 essay questions which refers to indicators of  mathematical communication skills. Determination of the sample is done using the total , Sampling technique, Based on the results of data processing, 12 students (85,7%) are belonged to “Hight" category because they are able to complate the three indicators of mathematical communication skills hingt, and 5 students (14,2%) are in medium Category, because they are sbic to complete the three indicators of mathematical communication ability well but are wrong in writing symbols. Keywords: Mathematical Logic, Mathematical Communication Skills, WhatsApp Media. AbstrakPenelitian ini bertujuan untuk mendeskripsikann keefektifan siswa dalam menyelesaikan soal logika  ditinjau dari kemampuan komunikasi matematis siswa di kelas XI SMA Swasta SwadayaTahun Ajaran 2020/2021. Jenis penelitian ini adalah deskriptif kualitatif. Subjek dari penelitian ini adalah 20 siswa kelas X1 SMA Swasta Swadaya Tahun Ajaran 2020/2021. Instrumen soal yang digunakan dalam penelitian ini berupa 3 butir soal berbentuk essay yang mengacu pada indikator kemampuan komunikasi matematis. Penentuan sampel dilakukan dengan menggunakan teknik Total Sampling.Berdasarkan hasil pengolahan data, diperoleh sebanyak 12 siswa (85,7%) termasuk dalam kategori “Tinggi”  karena mampu menyelesaikan ketiga indikator kemampuan komunikasi mmatematis tersebut dengan sangat baik, dan 5 siswa (14,2%) termasuk dalam kategori “Sedang” karena mampu menyelesaikan ketiga indikator kemampuan komunikasi mmatematis tersebut dengan  baik namun salah dalam menulis simbol.

Abstract

This study aims to determine whether there is a significant influence between mathematical problem solving abilities of students who are taught using cooperative learning pair check model is higher than the mathematical problem solving abilities of students who are taught by the lecture method in Mathematics teaching planning courses. The population in this study were all V semester students of the Mathematics Education Study Program FKIP UNA, taking a sample of two semesters totaling 72 students through a purposive sampling technique. The results of the study from the experimental semester obtained an average pretest of 65.1 and posttest average of 80.8. Whereas from the semester of control the average pretest was 65.5 and the posttest average was 75.1. Analysis of posttest data using the t test at the level of α = 0.05 obtained tcount = 2.75 while t table = 1.98 turned out t_count> t_tabel so that Ho is rejected and Ha is accepted. Then it can be concluded that the mathematical problem solving abilities of students taught by using the pair check learning model are higher than the students' mathematical problem solving abilities taught by the lecture method.
