The purpose of this study is to test the effectiveness of book of Scientific - Inquiry (SI) learning model which has been developed by Jusniar (2015) with an average of 3.20 with a coefficient of expert judgment index equal to a valid category, the practicality of the perception of the average student 89.47% and the average teacher 90.05% who responded positively to the application of models and tools. This study was conducted at three schools with different characteristics SMAN 1 Bajeng (Accreditation), SMAN Bontonompo (Accreditation B) and SMAN WestBajeng (Accreditation B). The research design used is quasi experiment with pre-test and post-test control group design. The instrument used to collect data is 1) the observation sheet process of scientific thinking skills, 2) questionnaire user perception and 3) test the product of scientific thinking skills. The Results of effectiveness testing of the SI model viewed from two aspects: the enforceability of Scientific Inquiry learning through observation and testing processes Scientific Thinking Skills (KBI) products. Observation process includes the ability / skills to formulate the problem, observe, hypothesize, ask questions, collect data, discussion and conclusion) the experimental class for each to: SMAN 1 Bajeng average KBI groups with both category and 76.79% enough category 23 , 21%, SMAN 1 Bontonompo good category 73.21%, 23.22% and sufficiently less 3.57%. And for SMAN 1 west Bajeng good category 67.86%, 28.57% and lacking sufficient at 3.57%. The effectiveness of the learning model Scientific-inquiry of the test results ANACOVA with SPSS for windows 20.0 was obtained respectively: 1) SMAN 1 Bajeng significance of the implementation of the model 0000 with a contribution of 26.2% against the influence of SI models KBI students; 2) SMAN 1 Bontonompo significance of the implementation of the model 0000 with a contribution of 44.9% influence model (SI) to KBI students; 3) SMAN 1 WestBajeng significance of the application of the model 0000 with a contribution of 24.0% influence on the KBI student models; meaning of the three schools that made the object to the implementation of the model and the device is considered effective to increase the KBI high school students on test material electrolyte and non-electrolyte solution.
