The usage of appropriate teaching material can help student achieve learning
objectives by motivate and attract student interest in order for them to study actively in
learning process. One of the teaching material that can be used to support the learning
process according to the 2013 curriculum is teaching materials in the form of Guided
Inquiry Based Student’s Worksheets. This research aims to determine the effect of
student’s worksheet based on guided inquiry for solubility and solubility product
constant toward 11th grade senior high school student’s study result. The research type
was quasi experiment research which used non-equivalent control group design. The
population was all 11th grade senior high school students from MAN 2 Padang on
2017/2018 academic year. The research sample was chosen using purposive sampling
technique which resulted XI MIPA 3 as the experiment class and XI MIPA 5 as the

which consists of pre-test and post-test. Based on this research, the N-gain point
obtained in this experiment class was 0.68 which considered medium and in the control
class was 0.55 which considered medium. The result based on the data analysis was
both sample class distributed normally and has homogeneous variance. Based on the ttest

showed that the increasing of student’s study result from experiment class was higher
than control class significantly. It can be concluded that the usage of student’s
worksheet on solubility and solubility product constant take effect and can be used to
increase 11th grade senior high school student’s study result.
