Kata Kunci: Keterampilan berpendapat, Kooperatif, Tipe STAD.  The aims of this study are to determine the students’ giving opinion skills and mastery learning  students through the implementation of cooperative learning model with STAD approximation electrolyte and non-electrolyte solution. The type of this research was pre experiment research and design research  was  "One  Shot  Case  Study". The  subjects were students of  X grade SMA Kemala Bhayangkari 1 Surabaya as many as 43 students in the 1st semester 2013-2014 school year. The instrument which was used to observe giving opinion skills students was questioning skills observation sheet.  For mastery of students learning outcomes were measured by using a sheet test for students learning outcomes. On the skills suggested for existing problems from the 1st meeting up to the 3rd meeting of the number of students who get a category A (very good) row of 6,98%, 18,60%, and 39,53%. Category B (good) row 41,86%, 58,14% and 53,49%. Category C (enough) row 34,88%, 18,60%, and 6,98%. Category D (less) row for 16,28%, 4,65% and 0,00%.
