Jembatan Keledai_1
Ide penulisan ini sebenarnya berawal dari siswa-siswi saya di sebuah lembaga bimbingan belajar dimana saya diminta untuk ikut bergabung. Saat itu hujan deras dan anak-anak bimbingan belum pulang. Sambil menunggu hujan reda, seorang siswi menanyakan salah satu materi SKL.
Pak gimana cara menghafalkan spektrum gelombang elektromagnetik, soalnya kan harus urut dari frekuensi besar dulu atau dari panjang gelombangnya dulu, kalo tidak urut sih aku bisa. Jangan jawab kuasai konsepnya lho pak, soalnya guruku kalo ditanya dikit-dikit jawabnya kuasai konseeeep.
Wah, sudah keduluan dijawab sendiri nih oleh yang tanya. Sesaat saya berfikir lalu saya jawab : Ya dibuat jembatan keledai lah.
Apa tuh pak ?
Lho gak tau to…. itu lho jembatan kecil buat nyeberangkan kambing.
Rupanya model-model pembelajaran yang pernah saya dapat dari Bapak/Ibu guru waktu saya sekolah dulu, nyaris sudah tak terdengar lagi. Padahal metode jembatan keledai ampuh juga kalo kita mau kreatif, yang jelas tidak kalah dengan metode pembelajaran berbasis IT dengan menggunakan laptop yang harganya mahal. Tapi bukan berarti saya tidak setuju dengan model sekarang, jangan salah paham bagi yang maniak dengan pembelajaran berbasis teknologi.
Akhirnya saya buatkan juga jembatan keledainya untuk menghafalkan spektrum gelombang elektromagnetik berdasarkan urutan dari frekuensi besar ke frekuensi kecil.
Perhatikan urutannya :
- sinar Gamma…… (frekuensinya paling besar)
- sinar X
- sinar Ultraviolet
- sinar Tampak
- sinar Inframerah
- gelombang Radar
- gelombang TV
- gelombang Radio….. (frekuensinya paling kecil)
Kita buat saja jembatan keledainya seperti ini :
Gadis X Ulangtahun Tampak Imut-imut kena Radar masuk TV dan Radio
rupanya anak-anak malah pada tertawa.
Artinya Pak ..?
Ga = sinar gamma ; X = sinar X, Ul = ultraviolet; Tampak = sinar tampak; Im = inframerah, Radar = gelombang radar, TV = gelombang TV, dan Radio = gelombang radaio.
Yang lain Pak…..yang lain.
Wah hujan sudah reda…….pulang dulu ya.
besok yang lain ya Pak……?
Sambil menuju motor saya jawab sekenanya,… Ya.
Catatan :
Mohon maaf untuk para pakar fisika barang kali cara yang saya pakai ini dianggap sebagai pembodohan siswa, saya tidak bermaksud demikian. Bagi saya, yang penting adalah bagaimana siswa merasa enjoi belajar, merasa tidak terbebani sesuatu yang dianggapnya sulit.

Hello, after reading this awesome post i am also happy to share my know-how here with mates.
Hey there, I think your site might be having browser compatibility issues.
When I look at your blog in Firefox, it looks fine but
when opening in Internet Explorer, it has some overlapping.
I just wanted to give you a quick heads up! Other then that,
fantastic blog!
keren pak… tapi kadang saya bingung bagaimana cara merangkai jembatan itu dengan menarik,,,, pernah saya coba buat,eh malah saya sendiri bingung dengan apa yang saya buat… jadi mohon bimbingannya pak…!!!
Wah gimana pemanfaatannya di matematika pak ? mampir juga dong ke blog sederhana saya …siapa tau bisa kasih ide2 dalam pembelajaran matematika SMP.Makasih….
Maaf bu, matematika menurut saya itu keterampilan. jadi siswa yang lebih banyak berlatih tentu saja lebih menguasai. Artinya dibutuhkan proses pembiasan. Siapa sih yang tidak tahu 5 x 5 = ?, semua pasti menjawab 25 bukan karena hafal tapi karena pembiasaan. penggunaan rumus praktis di matematika justru akan menyesatkan menurut saya. Saya lebih suka menggunakan logika praktis tanpa mengesampingkan konsep yang sesungguhnya.Waduh, maaf bu kok jadi ngelantur…..terima kasih Ibu sudah berkunjung di blog saya.

Tips yg bagus… perlu dicontoh..
terima kasih telah berbagi
Terima kasih atas kunjungannya.
Wah, akhirnya mau juga nih mampir di blog saya yang masih acak-acakan. Terima kasih bang. Jangan bosan kalau saya sering merepotkan, jangan kesal kalau saya sering tanya, dan jangan mengeluh kalau kalau sering gak mudeng.
Gawe gravatar, Pak (lewat edit profil). Kalau gak mau pake foto ya pake logo TS spt yg ada di media2 njenengan.
Teguh Sasmito sdh saya add di Link Sahabat bloge nyong. Bloge p Nur jg sudah.
Ingat jembatan keledai jadi ingat MEJIKUHINIU.
