This research is a descriptive study that aimed to describe the quality of learning mathematics teacher at SMK Technology Tri Tunggal "45" based on the Model EKOP Makassar. Model EKOP is one Evaluation Model Learning Program, which not only assess the results (outputs) of learning, but also assesses the learning process carried out by the teacher. The instrument used in this study was a questionnaire given to teachers and students in mathematics teaching by the math teacher. The subjects were all teachers of mathematics in Technological Trinity "45". Analysis of the data used is the average of each component looks for good learning process and learning output, then compares to the quality standards that have been set. The results showed that (1) the quality of the learning process of mathematics teachers in the name of AMRN measured using Model EKOP is Good. (2) The quality of the learning process of mathematics teachers in the name JMT measured using Model EKOP is Good. (3) The output quality of learning mathematics teacher on behalf AMRN measured using Model EKOP is Good. (4) The output quality of learning mathematics teacher on behalf of JMT measured using Model EKOP is Moderate. (5) The quality of mathematics teacher learning program on behalf AMRN measured using Model EKOP are Good. (6) The quality of the learning program for mathematics teachers in the name JMT measured using Model EKOP is Moderate

Penelitian ini membahas tentang pengembangan buku saku digital berbasis STEM pada materi bangun ruang sisi datar kelas VIII. Penelitian ini bertujuan untuk mengembangkan buku saku digital berbasis STEM pada materi bangun ruang sisi datar kelas VIII yang memenuhi kriteria valid. Jenis penelitian yang dilakukan berupa research and development (R&D). Adapun model pengembangan yang digunakan adalah model ADDIE yang terdiri dari 5 tahap pengembangan, yaitu : (1) Tahap analisis (analyze), (2) Tahap perencanaan (design), (3) Tahap pengembangan (development), (4) Tahap implementasi (implementation), (5) Tahap evaluasi (evaluation). Namun dalam penelitian pengembangan ini hanya menggunakan tiga tahapan yaitu : (1) Tahap analisis (analyze), (2) Tahap perencanaan (design), (3) Tahap pengembangan (development). Penelitian ini dilakukan di SMP Negeri 2 Palopo dengan subjek penelitian adalah 3 ahli matematika khususnya ahli bidang materi matematika dan ahli bidang media matematika. Pengumpulan data dilakukan dengan teknik angket dengan instrument berupa angket validasi ahli isi/materi, dan ahli media. Berdasarkan hasil analisis angket, diperoleh hasil bahwa buku saku digital berbasis STEM pada materi bangun ruang sisi datar memenuhi kriteria valid untuk digunakan dalam pembelajaran matematika, dilihat dari hasil penilaian tiga validator ahli isi/ materi (90%) dengan kategori sangat valid dan ahli media dan design (91%) dengan kategori sangat valid.Kata Kunci : Bangun ruang sisi datar; buku saku digital; STEM.

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.

Sejumlah permasalahan dalam Sistem Persamaan Linear Dua Variabel (SPLDV), mendorong para peneliti melakukan kajian yang beragam. Namun, masih sedikit peneliti yang mengintegrasikan antara model pembelajaran dengan materi tersebut. Oleh karena itu, penelitian ini bertujuan untuk mendeskripsikan bagaimana  peningkatan pengetahuan SPLDV siswa melalaui pembelajaran kooperatif. Kami melakukan Penelitian tindakan kelas bersama dengan guru di kelas atau dilokasi penelitian dengan melibatkan siswa di tingkat menengah. Data yang dikumpulkan berupa observasi, tes, dan dokumentasi. Kami menggunakan analisa kuantitatif dan kualitatif untuk mendeskripsikan temuan. Dari hasil tersebut, kami menemukan bahwa terjadi  peningkatan pengetahuan siswa tentang SPLDV melalui model kooperatif. Lebih lanjut, peningkatan ini berdampak pada peningkatan aktivitas guru dan siswa dalam kelas serta meminimalkan kesalahan siswa dalam menyelesaikan masalah SPLD

Dunia pendidikan manjadikan kurikulum sebagai acuan dalam proses pembelajaran. Kurikulum 2013 mempunyai ciri khas pendidikan karakter serta mengarahkan siswa menjadi lebih aktif ketika proses pembelajaran. Sehingga diperlukan inovasi pembelajaran yang lebih menarik minat belajar siswa. Pada penelitian ini produk berupa lembar kerja siswa yang menggunakan pendekatan kontekstual berbasis ayat-ayat Al-Qur’an sebagai hasil akhir pengembangan, dengan model pengembangan ADDIE yang tahapanya yakni Analyze, Design, Development, Implementation, and Evaluation. Akan tetapi, tahap Development atau pengembangan dipilih penulis sebagai tahap akhir. Penelitian ini dilaksanakan pada kelas V MI Datok Sulaiman Palopo, adapun subjek pada penelitian ini yakni siswa kelas V dengan total 39 siswa. Untuk instrumen penelitian yang digunakan berupa instrumen wawancara guru, angket siswa dan tes siswa, Rancangan LKS telah direvisi berdasarkan masukan dan saran dari para ahli seperti ahli materi dan desain, ahli bahasa dan ahli ayat Al-Qur'an. Untuk mengetahui validitas atau kelayakan produk yang dikembangkan, maka dilakukan uji validasi oleh beberapa ahli, diantaranya adalah hasil validasi dari ahli materi yang mencapai persentase 87,5% (sangat valid), sedangkan hasil validasi dari ahli bahasa mencapai persentase 87,5% (sangat valid), dan hasil validasi ahli terhadap Ayat Al-Qur'an mencapai persentase 90% (sangat valid).
