Abstract

This research were aimed to describe the validity of assessment instrument of science process skill on the salt hydrolisys topic and to describe responses teachers and to describe the level of difficulty of the questions in the assessments, about the validity item and reliability. This research used RD method of Borg and Gall which steps start from research and information collecting until main field revision. This product was an instrument categories in the form essay written tests that measure the basic science process skills of students. The validation results were valid instrument developed by the high category in conformity aspects of content, very high category on aspects of construct and readability. And the result of responses teachers indicated that very high on content suitability and readability aspects. The empirical testing showed that this assessment instrument have high level of reliability, modest level of difficulty, and modest validity.Penelitian ini bertujuan untuk mendeskripsikan validitas instrumen asesmen keterampilan proses sains (KPS) pada materi garam hidrolisis, mendeskripsikan tanggapan pendidik, serta mendeskripsikan tingkat kesukaran soal-soal dalam asesmen, validitas butir soal dan reliabilitas. Metode yang digunakan dalam penelitian ini adalah RD menurut Borg and Gall dari tahap studi pendahuluan sampai tahap revisi hasil uji coba lapangan awal. Instrumen asesmen ini merupakan instrumen dengan kategori tes tertulis dalam bentuk esai yang mengukur KPS dasar peserta didik. Hasil validasi ahli pada aspek kesesuaian isi memiliki kategori tinggi, pada aspek konstruks dan aspek keterbacaan berkategori sangat tinggi dan dikatakan valid. Tanggapan pendidik pada aspek kesesuaian isi dan keterbacaan menunjukkan kategori sangat tinggi. Uji empiris menunjukkan asesmen memiliki reliabilitas tinggi, tingkat kesukaran soal sedang dan validitas butir sedang.Kata kunci: asesmen, KPS, garam hidrolisis, validitas, reliabilitas

Abstract

This research was quasi experiment with non-equivalence (pretest-posttest) control group design. This research was conducted at SMAN 3 Bandarlampung with purpose to describe the effectiveness of scientific approach to increase studentsattributingability on salt hydrolysistopic. The samples in this research were taken by using purposive sampling and it was acquired the MIA4 and MIA5 of the 11th grade in even semester of 2014-2015 academic year. Learning was said effective, if there are statistically significant difference of the n-Gain average in the control and experimental classes. The results showed that the average n-Gain of attributing students ability in the control and experimental classes were 0.41 and 0.56,respectively.So,it was concluded that theuse of scientific approach on the salt hydrolysis topicwas effective in improving the ability of attributing.Penelitian ini adalah kuasi eksperimen dengan Non Equivalence Control Group Design. Penelitian ini dilakukan di SMA Negeri 3 Bandar Lampung dengan tujuan mendeskripsikan efektivitas pendekatan saintifik dalam meningkatkan kemampuan attributing siswa pada materi hidrolisis garam. Sampel dalam penelitian ini diambil dengan menggunakan purposive sampling dan diperoleh kelas MIA4 dan MIA5 dari kelas XI di semester genap tahun akademik 2014-2015. Pembelajaran dikatakan efektif apabila secara statistik kemampuan attributing siswa menunjukkan perbedaan rata-rata n-Gain yang signifikan antara kelas kontrol dan eksperimen. Hasil penelitian menunjukkan rata-rata n-Gain kemampuan attributing siswa untuk kelas kontrol dan eksperimen masing-masing 0,41 dan 0,56. Maka, disimpulkan bahwa penggunaan pendekatan saintifik pada materi hidrolisis garam efektif dalam meningkatkan kemampuan attributing.Kata kunci: hidrolisis garam, kemampuan attributing, pendekatan saintifik.
