Instrumen yang digunakan adalah lembar validasi, lembar observasi aktivitas siswa, lembar observasi kemampuan guru dalam mengelola pembelajaran, angket respons guru, angket respons siswa, dan tes hasil belajar. Hasil penelitian menunjukkan bahwa rata-rata skor hasil validasi media pembelajaran adalah 3,45 berada pada kategori valid. Rata-rata skor yang diperoleh berdasarkan respons guru dan respons siswa terhadap media pembelajaran sebesar 93,1% dan 96,9% yang menunjukkan media pembelajaran ini praktis. Kemampuan guru dalam mengelola pembelajaran dengan rata-rata 3,87 berada pada kategori sangat baik, aktivitas siswa dalam kategori sangat baik yakni 94,75%, dan tes hasil belajar berada pada kategori tinggi dengan persentase ketuntasan belajar keseluruhan siswa sebesar 83,08%. Dapat disimpulkan bahwa media pembelajaran interaktif berbasis multimedia memenuhi kriteria kevalidan, kepraktisan, dan keefektifan.

Artikel ini bertujuan untuk mengetahui kemampuan pemahaman konsep mahasiswa berdasarkan indikator pemahaman matematis pada mata kuliah aljabar linear elementer materi ruang vektor, sub ruang vektor, dan vektor Euclidean. Penelitian ini menggunakan pendekatan deskriptif kualitatif. Subjek penelitian meliputi mahasiswa jurusan pendidikan matematika fakultas tarbiyah dan keguruan UIN Alauddin Makassar angkatan 2016 yang diduga mengalami kesulitan dalam memahami konsep pada mata kuliah aljabar linear elementer. Instrumen penelitian yang digunakan adalah tes diagnostik dan wawancara. Teknik analisis data yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa kemampuan pemahaman mahasiswa jurusan pendidikan matematika UIN Alauddin Makassar angkatan 2016 dalam menyelesaikan soal aljabar linear elementer ditinjau dari indikator kemampuan pemahaman matematis, mahasiswa tergolong cukup mampu pada indikator: (1) pemahaman mampu menyatakan ulang sebuah konsep, (2) menyajikan konsep dalam berbagai bentuk representasi matematika, (3) menggunakan, memanfaatkan dan memilih prosedur tertentu, dan (4) mengaplikasikan konsep/algoritma ke pemecahan masalah. Namun, mahasiswa tergolong tidak mampu pada indikator kemampuan memberi contoh dan bukan contoh.

Calculus is a branch of mathematics that is applied to solve various problems in various fields of science such as engineering, physics, medicine, chemistry, economics, and various other sciences. However, most students assume that calculus is an elusive material. Therefore, it is necessary to have a study of the difficulties of students in solving calculus questions, given the very importance of this concept in taking the next course. This study is qualitative descriptive research that involved forty-two second semester students of the Mathematics Education Program of IAIN Palopo, and six of them are the interview subjects. In data collection, it used written tests and interviews. Furthermore, the data obtained are then analyzed through reduction, data presentation, and conclusions withdrawal. The findings show that the students get learning difficulties in reading by 52.38%, in writing by 66.67%, and in accounting by 57.14%. The factors causing these difficulties, namely students are not able to identify questions, difficulties in using integral symbols, difficulties in using proper techniques and formulas, difficulties in understanding the steps to solve partial integral problems, difficulties in calculations, difficulties in solving until the final stage of the integral process.

The study aims to find out the suitability of the mathematics teachers’ lesson plan with the 2013 curriculum, the mathematics teachers’ learning implementation with the 2013 curriculum, and the lesson plan with the mathematics teacher’s learning activities with the 2013 curriculum. The study used descriptive research with qualitative approach. The research subjects were 3 mathematics teachers of class X in the State Senior High School (SMAN) 11 Makassar. The documentation, observation sheet, and interview guidelines were the instruments used in this study. The analysis results of the lesson plan with the learning activities based on the 2013 curriculum in accordance with the cultural and education ministry regulation number 22 of the year 2016 about the Elementary and Secondary Education Standard Processes showed that the suitability of those three mathematics teachers’ lesson plans with the learning implementation of the 2013 curriculum was categorized as very high with the percentage of 94.44%, the suitability of the learning implementation in SMAN 11 Makassar at class X with the learning implementation of the 2013 curriculum was categorized as high with the percentage of 81.68%, and the suitability of the lesson plan with the learning implementation based on the 2013 curriculum in SMAN 11 Makassar at class X was categorized as low with the percentage of 62.17%. The study finding also indicated that there was unsuitability between the lesson plan and the mathematics teachers’ learning implementation of the 2013 curriculum at class X of SMAN 11 Makassar.
