Abstract


Penelitian ini dilaksanakan untuk mengetahui pengaruh implementasi strategi Predict- Observe- Explain (POE) berbasis intertekstual terhadap pemahaman siswa tentang faktor konsentrasi dan luas permukaan terhadap laju reaksi. Penelitian ini menggunakan metode kuantitatif One Group Pretest-Posttest Design dan melibatkan 26 siswa kelas XI jurusan MIPA sebagai subjek penelitian. Implementasi pembelajaran strategi POE berbasis intertekstual dibantu dengan penggunaan LKPD dan Instrumen Tes Diagnostik Mental (TDM) dua tingkat digunakan untuk memperoleh hasil pemahaman siswa. Analisis data hasil penelitian digunakan N-Gain dan kategorisasi jawaban siswa untuk melihat peningkatan nilai yang diperoleh oleh siswa. Perhitungan N-Gain menunjukkan terdapat 1 siswa dengan kategori peningkatan tinggi, 20 siswa peningkatan sedang dan 5 siswa peningkatan rendah. Pola sebaran jawaban siswa pun menunjukkan adanya peningkatan pemahaman yang dialami siswa. Pada awal pembelajaran, kategori jawaban siswa pada soal pretest mayoritas adalah Benar-Salah dan Salah-Benar yang mana menunjukkan adanya miskonsepsi. Sedangkan setelah implementasi, kategori jawaban siswa pada soal posttest mayoritas adalah Benar-Benar yang menunjukkan siswa paham akan konsep.
