<![CDATA[Penelitian ini bertujuan untuk melihat efektivitas penggunaan blok aljabar dalam rangka membantu siswa kelas IX menyelesaikan permasalahan persamaan kuadrat dengan teknik kuadrat sempurna. Blok aljabar digunakan dalam rangka untuk membantu siswa dalam menghadapi kesulitan-kesulitan yang muncul dalam berpikir abstrak yang dibutuhkan ketika menyelesaikan persamaan kuadrat dengan teknik kuadrat sempurna. Ini penting untuk dikaji karena kesulitan dalam berpikir abstrak dalam menggunakan teknik kuadrat sempurna adalah salah satu hambatan yang dialami oleh siswa-siswa kelas IX dalam menyelesaikan masalah persamaan kuadrat dengan teknik kuadrat sempurna. Hasil dari eksperimen memperlihatkan bahwa proses pembelajaran dengan menggunakan blok aljabar dalam menyelesaikan persamaan kuadrat dengan teknik kuadrat sempurna memberikan hasil yang lebih baik dari pembelajaran yang dilakukan dengan metode konvensional .]]>

<![CDATA[Abstract This research is a qualitative descriptive research that aims to investigate the mathematical problem solving after learning with MEAs on linier equation system of three variables. The subject of this research are 5 students of X class of MIA 6 SMA Negeri 10 Palembang. The data of this study was collected by three item of problem solving test on SPLTV and an interview to obtain the data deeply. The result of this study show that the indicator of problem solving that the most often appear is indicator of understanding the probelm,where this indicator appears at each level of ability of students, namely high, medium, and low. While indicator that are very rare to appear are indicator looking back. Where this indicator only appears at the level of the ability of students is high, while for the the level of ability of students who are moderate and low this indicator does not appear. The cause of this indicator rarely arises because most students ignore the command to look back, students feel enough to get the final results without re-analyzing the results that have been obtained. Keywords: Analysis, Model Eliciting Activities, Problem Solving]]>

<![CDATA[Koneksi matematis merupakan salah satu kemampuan yang harus dimiliki siswa dalam mempelajari matematika di sekolah. Melalui koneksi matematis, siswa dapat lebih mudah dalam menyelesaikan soal terutama soal olimpiade. Hal tersebut dikarenakan dalam pengerjaan, soal olimpiade membutuhkan penalaran dan pemahaman konsep serta hubungan antar konsep secara mendalam. Penelitian ini mengangkat tentang kemampuan koneksi matematis berdasarkan tipe kepribadian Sensing-Intuiting, karena tipe Sensing cenderung pada pengetahuan prosedural sedangkan Intuiting cenderung pada pemrosesan data berdasarkan pola dan hubungan secara konseptual dan melihat kemungkinan yang terjadi. Tujuan dari penelitian ini adalah mendeskripsikan kemampuan koneksi matematis siswa berkepribadian Sensing – Intuiting dalam menyelesaikan soal olimpiade. Jenis penelitian ini adalah deskriptif kualitatif, penelitian ini dilaksanakan di salah satu SMP yang ada di Surabaya dengan subjek sebanyak 2 siswa yaitu 1 siswa tipe Sensing dan 1 siswa tipe Intuiting. Subjek dipilih menggunakan angket Myers-Briggs Type Indicator (MBTI) dan diuji dengan 3 soal olimpiade yang kemudian diwawancara. Hasil analisis menunjukkan bahwa siswa berkepribadian Sensingmemiliki kemamuan koneksi matematis sedang dengan rata-rata nilai adalah 3, sedangkan siswa berkepribadian Intuiting memiliki kemampuan koneksi matematis tinggi denga rata-rata nilai adalah 4,6.]]>

<![CDATA[This study aims to describe students' mathematical representations in a cognitive style of visualizers in solving TIMSS problems. This research is a qualitative descriptive study. In this study consisted of 4 students where 2 of them were students with low and high cognitive style visualizers, and 2 others were students with low and high cognitive verbalizer styles. The instruments in this study were the researchers themselves and assisted with cognitive style questionnaire sheets, TIMSS test sheets, and interview guidelines. Data collection techniques used were in the form of cognitive style tests, TIMSS test questions, and student interviews. The technical data analysis used is data reduction, data presentation, and drawing conclusions. The results of this study are that mathematical representations with cognitive visualizer style are able to work on the questions in the form of images or illustrations well through the stages set by the researcher, namely; the interest in the question according to its cognitive style, understanding the problem more than the student who has a positive verbalizer style, uses a better solution to approach the perfection of the answer. Students' mathematical representations in the cognitive verbalizer style are able to work on questions presented with story or narrative questions that are easier to understand and able to describe well and are able to represent in mathematical languages.]]>

<![CDATA[Kesenian Marawis merupakan budaya Nusantara yang bernuansa religi. Kesenian ini berkembang di beberapa daerah di Indonesia, salah satunya di Provinsi Kepulauan Riau. Pada kesenian Marawis terdapat indikasi adanya praktek matematis terutama pada corak alat musiknya. Praktek matematis dalam budaya dikenal dengan etnomatematika. Penelitian ini bertujuan untuk mendeskripsikan hasil eksplorasi etnomatematika pada corak alat musik kesenian Marawis Provinsi Kepulauan Riau yang dapat dijadikan sebagai sumber belajar matematika. Jenis penelitian ini merupakan penelitian kualitatif dengan pendekatan etnografi. Sumber data merupakan anggota tim Marawis Sekolah Mengengah Kejuruan Negeri 4 Tanjungpinang dan alat musik marawis. Pengumpulan data dilakukan dengan observasi, wawancara, dan dokumentasi dengan instrumen utama penelitian adalah peneliti sendiri. Kemudian data dianalisis dengan mengacu pada rancangan Miles and Huberman dengan mereduksi data, penyajian data, serta kesimpulan/verifikasi. Hasil penelitian menemukan adanya praktik matematis berupa bangun geometri yaitu bidang datar dan konsep matematika yang meliputi konsep translasi, refleksi, simetri lipat, simetri putar, sudut lancip dan tumpul, serta bidang lingkaran.]]>

<![CDATA[Penelitian ini dilakukan untuk menganalisis kualitas perangkat dan keterampilan mengajar dengan menggunakan analisis Model Rasch. Penelitian dengan pendekatan kualitatif bersifat deskriptif ini dilakukan pada subjek penelitian mahasiswa semester V tahun akademik 2017/2018 Program Studi Pendidikan Matematika FKIP Universitas Maritim Raja Ali Haji pada mata kuliah Micro Teaching. Data yang digunakan berjenis primer/langsung yang diperoleh melalui teknik penugasan berupa perangkat pembelajaran yang terdiri atas silabus mini, Rencana Pelaksanaan Pembelajaran (RPP) mini, dan media pembelajaran. Data berikutnya diperoleh melalui observasi pada aspek keterampilan mengajar yang merupakan tolok ukur dalam proses pembelajaran. Kemudian dilakukan penilaian terhadap kedua sumber data tersebut dengan menggunakan instrumen lembar penilaian perangkat dan keterampilan mengajar yang memuat indikator-indikator terkait dengan teknik rating scale sehingga menghasilkan data ordinal. Data mentah dari kedua sumber diolah dan dianalisis menggunakan Model Rasch dengan software Ministep. Analisis yang dilakukan adalah person measure, item measure, dan person map item. Hasil analisis dipaparkan dengan teknik deskriptif kualitatif guna menggambarkan kualitas perangkat dan keterampilan mengajar. Hasil analisis perangkat diperoleh bahwa kualitas rata-rata perangkat pembelajaran disusun oleh mahasiswa berada di atas rata-rata taraf kualitas standar perangkat. Terdapat 71% dari total mahasiswa yang memiliki kualitas setiap item pada perangkat di atas rata-rata standar. Hasil analisis pada aspek mengajar diperoleh kualitas rata-rata mengajar mahasiswa lebih tinggi dari rata-rata taraf kualitas mengajar standar. Terdapat sekitar 46,4% dari total mahasiswa yang memiliki kualitas mengajar setiap itemnya berada di atas kualitas rata-rata.]]>
