Daftar Isi:
- This research was aimed to describe the effectiveness of problem based learning model to improve the students’ original thinking ability of acid base topic. This research was conducted at one of Senior High School in Bangun Rejo with using kuasi experiment method with Non Equivalent Pretest Posttest Control Group Design. The sample was obtained by cluster random sampling technique and it was obtained sample was the XI IPA 2 as control class and XI IPA 4 as experiment class.
