Abstract

This research aims to investigate the effect of the Problem-Based Learning (PBL) learning model on the mathematical communication skills of class XI MAS students at the UNIVA Medan Project, with the help of the FlipHTML5 application. The method used in this research is quasi-experimental with a factorial design. Data collection was carried out through mathematical communication skills tests and statistical analysis to test hypotheses. The results showed that there was a significant increase in the mathematical communication skills of students in the experimental group compared to the control group. The average posttest score for the experimental group was 85.52, while the control group was 78.04. It is indicated that this difference did not occur by chance, but rather was the result of differences in the treatment applied. In addition, the FlipHTML5 application was proven to be effective in improving students' mathematical communication skills with an average score percentage of 73.63% in the experimental class compared to 71.37% in the control class. These results indicate that the use of the FlipHTML5 application in learning with the PBL model makes a positive contribution to improving students' mathematical communication skills.

Abstract

The feasibility results were obtained based on the results of the validation questionnaire for the mathematics derivative board props for each validator, namely media experts, who obtained a percentage result of 78.24% in the "Good" category. The material expert obtained a percentage result of 86% in the "Very Good" category. Small group students obtained a percentage result of 83.5% in the "Very Good" category. The average percentage of the three validators is 82.63% in the "Very Good" category. In this way, the mathematics-derived board teaching aids are declared suitable for use in the learning process. This result is based on the average pretest score of 40.5 and the average posttest data result is 83.5 and the N-Gain calculation is 0.72 with the interpretation "High" so it can be said that there is an increase in understanding of mathematical concepts.Keywords: tools display; board derivative mathematics; understanding draft

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penalaran matematika siswa menggunakan metode Scientific Approachpada mata pelajaran matematika materi himpunan dikelas IX B EX PGA PROYEK UNIVA MEDAN. Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian variabel terikat dengan desain berfokus pada pretest danposttes. Populasi yangdigunakan dalam penelitian ini adalah siswa kelas IX B dengan jumlah siswa nya 19 orang. Teknik pengumpulan data dalam penelitian ini dengan menggunakan observasi  sebelum penelitian, uji t dan uji t deskriptif dengan tarap signifikan  (a) = 5 % berdasarkan hasil penelitian, pengolahan, dan analisis data, menunjukan terdapat pengaruh penggunaan lembar kerja peserta didik (LKPD) berbasis scientific approach untuk penalaran matematika siswa dikelas IX B EX PGA PROYEK UNIVA MEDAN 2022 /2023.
