Abstract

Penelitian ini bertujuan untuk mengidentifikasi faktor apa saja yang menyebabkan rendahnya hasil belajar peserta didik. Penelitian ini dilakukan di SMK Negeri 1 Tonjong karena nilai rata-rata ujian nasional mata pelajaran matematika di sekolah tersebut setiap tahunnya paling rendah dibanding mata pelajaran yang lain. Metode penelitian ini menggunakan metode deskriptif kualitatif dengan teknik pengumpulan data observasi melalui angket dan wawancara. Hasil penelitian ini menunjukan bahwa rendahnya hasil belajar ternyata dipengaruhi oleh beberapa faktor, yaitu faktor internal yang mencakup peserta didik tidak tertarik dengan matematika, kemampuan dasar berhitung siswa lemah, rendahnya pemahaman konsep peserta didik, peserta didik tidak mengerti lambang-lambang dalam matematika, kurangnya kedisiplinan peserta didik, dan kurangnya motivasi belajar peserta didik. Faktor eksternal mencakup ruang kelas yang panas sehingga membuat tidak nyaman, ruang kelas teori yang bising karena dekat dengan ruang praktik sehingga fokus peserta didik tidak optimal, dan faktor dari guru, yaitu kurang menarik peserta didik dalam menyampaikan materi sehingga peserta didik merasa bosan dan tidak berani bertanya.

Abstract

As many as 7.03% of people with disabilities in Indonesia are deaf people. The problem for deaf students is the lack of mathematics learning resources during learning and the low mathematical communication skills of deaf students. The purpose of this study is to analyze the development of sign language learning videos to improve mathematical communication of deaf students of fractional material in terms of validity, practicality, and effectiveness. The method used is the R&D method with a 4D model. The results showed that the validity of the media resulted in a very valid category by sign language experts with a score of 85% and material experts with a score of 83% and categories valid by media experts with a score of 78.5%. The results of media practicality of 100% for teacher and student responses and learning implementation questionnaires are said to be very practical. The results of the control class pretest and the experiment resulted in a sig value. > 0.05, then the data is normal. Homogeneity test with (6,14) <  (19) on pretest questions and (4,68) <  (19) on posttest questions then homogeneous data. Student scores resulted in a difference in the average student learning outcomes between the experimental class and the control class indicated by the T test results with the sig value. (0.001) < 0.05. The average value of the N Gain of the experimental class is greater than that of the control class, which is 0.9721 with a high category. so that the media is said to be valid, practical, and effective.
