“Mathematics” or “Mathematizing”

Wah, lama ga update blog ni. Minggu ini, kami mahasiswa IMPoME Utrecht 2012 sedang disibukkan dengan sederetan aktivitas perkuliahan yang melelahkan ditemani sederetan kisah sedih, forum diskusi yang memanas dan berimbas di facebook, pengalaman pertama kali bersepeda di Belanda, tugas yang menumpuk, hingga hal-hal menggelikan yang selalu saja ditanggapi dengan tawa. Masih ditemani oleh dinginnya udara musim dingin, saya mencoba berbagi beberapa tasks yang saya telah kerjakan di mata kuliah Introduction in Realistic Mathematics Education (RME) yang diasuh oleh Mieke Abels ditemani oleh Martin Dolk.

Sedikit deskripsi tentang perkuliahan ini, mata kuliah ini seharusnya diasuh oleh Jaap De Hertog, seorang ahli RME. Nah, dikarenakan Jaap sedang mengalami proses penyembuhan pasca operasi kanker, oleh karena itu Mieke lah yang mengisi kekosongan itu. Semoga cepat sembuh ya Jaap, we miss you. Pada pertemuan pertama kita mempelajari beberapa video hasil riset yang terdapat di TIMSSVideo, kemudian dilanjutkkan dengan memganalisis dan mencoba membuat “Didactical Triangular” dari video-video tersebut. Selanjutnya, diakhir pembelajaran, kita diminta uuntuk membaca sebuah literatur yaitu chapter 1 dari buku Young Mathematician At Work (2001) karya C.T. Fosnot & M.L.A.M. Dolk. Sebagai evaluasi dari kegiatan membaca ini, kita diminta untuk membuat list kata-kata, kalimat, penting, dan summary nya. Berikut hasil resume saya. Baca lebih lanjut

Al-Kashi

Ghiyath al-Din Jamshid Mas’ud al-Kashani or Al-Kashi who was born in 1380 in Khasan and died in 22 June 1429 at Samarkand is an astronomer and one of the best mathematician in Islam. He spent her life in Mathematics and Astronomy

Details of Jamshid al-Kashi‘s life and works are better known than many others from this period although details of his life are sketchy. One of the reasons we is that he dated many of his works with the exact date on which they were completed, another reason is that a number of letters which he wrote to his father have survived and give fascinating information.

Al-Kashi was born in Kashan which lies in a desert at the eastern foot of the Central Iranian Range. At the time that al-Kashi was growing up Timur (often known as Tamburlaine) was conquering large regions. He had proclaimed himself sovereign and restorer of the Mongol empire at Samarkand in 1370 and, in 1383, Timur began his conquests in Persia with the capture of Herat. Timur died in 1405 and his empire was divided between his two sons, one of whom was Shah Rokh.

While Timur was undertaking his military campaigns, conditions were very difficult with widespread poverty. al-Kashi lived in poverty, like so many others at this time, and devoted himself to astronomy and mathematics while moving from town to town. Conditions improved markedly when Shah Rokh took over after his father’s death. He brought economic prosperity to the region and strongly supported artistic and intellectual life. With the changing atmosphere, al-Kashi’s life also improved markedly. The first event in al-Kashi’s life which we can date accurately is his observation of an eclipse of the moon which he made in Kashan on 2 June 1406. Baca lebih lanjut

Kunjungan ke Daltonshool Rijnsweerd (Part 1)

Hari ini (31 January 2012) kami, mahasiswa batch 3 IMPoME melakukan kunjungan ke salah satu sekolah unik yang ada di Utrecht, Belanda. Tujuan kunjungan ini adalah melihat sejauh mana perbedaan kurikulum yang diterapkan di sekolah ini dengan sekolah-sekolah yang ada di tanah air. Di awali dengan  serangkaian kisah lucu tentang bagaimana paniknya wajah salah satu teman kami karena perubahan jalur bus yang diluar dugaan (maklum baru) sampai berjumpa dengan warga negara Belanda yang menyapa ramah dengan bahasa Indonesia, hingga ngalur ngidul mencari bus stop station. Pagi hari yang masih terbilang sangat gelap, sisa-sisa salju semalam, hingga suhu udara yang sangat teramat dingin buatku yang biasa hidup di wilayah tropis (-5 derajat celcius) ikut mewarnai perjalan kami, anak-anak ayam, demikian kami memberi nama geng aneh ini.
