Abstract

Kemampuan pemahaman konsep matematis merupakan salah satu tujuan pembelajaran matematika yang harus dicapai oleh siswa. Namun, kemampuan pemahaman konsep matematis siswa kelas X IPS SMAN 2 Padang belum menjadi perhatian secara maksimal. Cara yang dilakukan adalah dengan menganalisis kemampuan pemahaman konsep siswa melalui pemberian tes. Tujuan penelitian ini adalah untuk melihat kemampuan pemahaman konsep di kelas X IPS SMAN 2 Padang. Jenis penelitian yang dilakukan adalah penelitian deskriptif. Subjek penelitian adalah siswa kelas X IPS 1 SMAN 2 Padang. Instrumen penelitian yang digunakan adalah observasi lapangan dan tes berbentuk essay. Tes kemampuan pemahaman konsep matematika dianalisis berdasarkan rubrik kemampuan pemahaman konsep matematis. Hasil penelitian menunjukkan bahwa rata-rata kemampuan pemahaman konsep 49,35 dikategorikan cukup, indikator yang tertinggi adalah mengembangkan syarat perlu dan syarat cukup suatu konsep, dan yang terendah mengaitkan berbagai konsep dalam matematika maupun di luar matematika.

Abstract

The purpose of this research is to produce valid, practical and effective Flipped Classroom-based mathematics learning tools and to improve students' mathematical communication skills. The method used in this research is the Ploom development model. The development of the Plomp model is namely the initial investigation phase, the development phase, and the assessment phase. Learning tools developed in the form of lesson plans, student worksheets and learning videos. The subjects of the field test were students and educators in class X of SMAN 3 Jambi for the 2020-2021 academic year. The research instruments used were instruments at the initial investigation stage, validity test instruments, practicality test instruments and effectiveness test instruments. The results of the validation of the Flipped Classroom-based mathematics learning device were valid in terms of construct and content. The validity values ​​obtained for lesson plans, learning videos, and worksheets are 3.41; 3.17; and 3,4. Flipped Classroom-based math learning tools are practical in terms of implementation and ease of use. The results of the questionnaire analysis of the student's practicality data showed a figure of 81% so that it was categorized as practical from the observation data on the implementation of learning and interviews. The resulting learning devices are effective in improving students' mathematical communication. The results of the final test of students' mathematical communication skills are 77.78% of students who have scored above the KKM.
