Abstract

This research was aimed to describe the effectiveness of scientific approach in increasing student’s evaluative thinking skill in acid-base subject matter. The population of this research was all students grade XI in science class of SMA Negeri 3 Metro at second semester of academic year 2013-2014. Sampling was taken by purposive sampling and obtained class of  XI IPA 3 dan XI IPA 5 as sample.  The research method used quasi experimental with non equivalent control group design. The effectiveness of scientific approach in the learning was showed by the significant n-gain difference between the experimental class and the control class. The result showed that average n-gain of  evaluative thinking skills of control class was 0,25 and 0,56 for experiment class. From the hypotesis testing, it was concluded that  scientific approach was effective in increasing the evaluative thinking skill in acid-base subject matter.Penelitian ini bertujuan untuk mendeskripsikan efektivitas pendekatan ilmiah dalam mening­kat­kan keterampilan berpikir evaluatif siswa pada materi asam-basa.  Populasi da­lam penelitian ini adalah seluruh siswa kelas XI IPA SMA Ne­geri 3 Metro semes­ter genap Tahun 2013-2014.  Pengambilan sampel dilakukan dengan purposive sam­pling dan diperoleh kelas XI IPA 3 dan XI IPA 5 sebagai sampel.  Metode pe­ne­litian ini adalah kuasi eksperimen dengan Non Equivalent Con­trol Group Design.  Efektivitas pendekatan ilmiah dalam pembelajaran ini ditunjukkan oleh perbedaan  n-gain yang signifikan antara kelas kon­­trol dan kelas eks­perimen.  Hasil penelitian menunjukkan rata-rata n-gain  keterampi­lan berpi­kir evaluatif kelas control adalah 0,25 dan 0,56 untuk kelas eksperimen.  Dari pengujian hipotesis, disimpulkan bahwa penggunaan pendekatan ilmiah efektif dalam meningkatkan keterampilan berpikir evaluatif pada materi asam-basa.Kata kunci: asam basa, berpikir evaluatif, pendekatan ilmiah.
