Abstract

INDONESIA Penelitian ini dilatarbelakangi kerena konsep laju reaksi secara keseluruhan merupakan konsep yang bersifat abstrak dan konsep yang menyatakan simbol, maka diperlukan suatu pembelajaran yang mengembangkan metode praktikum dan penggambaran molekul untuk mendukung pemahaman konsepnya, untuk mengatasi permasalahan tersebut diterapkan pembelajaran CRA (Concrete-Representational-Abstract) yang mempunyai fokus utama pada pemahaman konsep dan demonstrasi siswa terhadap materi belajar. sehingga penelitian ini bertujuan untuk mendeskripsikan aktivitas siswa pada proses pembelajaran CRA, menganalisis kemampuan siswa menyelesaikan LKS setiap tahap pembelajaran CRA dan menganalisis hasil belajar siswa pada konsep laju reaksi setelah pembelajaran CRA. Metode yang digunakan dalam penelitian ini yaitu penelitian kelas terhadap siswa kelas XI IPA 1 SMAN 1 Jampangkulon Sukabumi dengan jumlah siswa 40 orang. Instrumen penelitian yang digunakan adalah deskripsi pembelajaran, lembar observasi, LKS dan tes evaluasi. Pengolahan data dilakukan sesuai jenis data dan instrumen yang digunakan. Hasil penelitian menunjukkan pembelajaran terlaksana dengan baik dengan nilai rata-rata persentase keterlaksanaan 80%. Kemampuan siswa dalam menyelesaikan LKS berdasarkan tahapannya memiliki nilai rata-rata 80 kategori baik. hasil belajar siswa melalui pembelajaran CRA memperoleh nilai rata-rata 73 dengan kategori baik. Berdasarkan data tersebut dapat disimpulkan bahwa siswa mampu mengembangkan hasil belajar dengan menggunakan model pembelajaran CRA pada konsep laju reaksi. ENGLISH This research background because runaway speed concept reacts wholly constitute concept that gets abstraction and concept character that declares for symbol, therefore needful a learning that develops to methodic praktikum and molecule delineation to back up its concept grasp, to settle about problem learning applies that CRA ( Concrete Representational Abstract) that have main focus on understanding concept and student demonstration to learned material. so this research intent to describe student activity on processes learning CRA , analisis is student ability solves LKS each learning phase CRA and analisis usufructs to study student on reactions fast concept after learning CRA . Method that is utilized in this research which is class research for student to braze XI IPA 1 SMAN 1 Jampangkulon Sukabumi by totals student 40 person. Observational instrument that is utilized is learning description, observation sheet, LKS and essays evaluation. Data processing is done accords data and instrument type that is utilized. Result observationaling to point out performed learning with every consideration with performed percentage average value 80%. Student ability in solves LKS bases its step have average value 80 good categories. students learned result pass through learning CRA getting average value 73 by good categories. Base that data gets to be concluded that student can develop studying result by use of CRA'S learning model on reactions fast concept.
