Abstrack Background of the research is the poor performance of students' learning. The aims of the research are know the difference of learning outcomes, and influence between students who are taught by practical method and responses with feedback and the students that taught by lecture method possible to the material electrolyte and non-electrolyte of X class of MAS DU. The form of the study is a Quasi Exsperimental Design with the design of a "Nonequivalent Control Group Design". Data collection tool used consisted of tests of learning outcomes and questionnaire. Posttest data analysis were using t test (α = 5%) values obtained Asymp.Sig (2-tailed) of 0.003, indicating that there were a difference in student learning outcomes among students taught with practical method with feedback and students who were taught by lecture method. Students’ responses taught by lecture method is 69% which is quite strong. Student response taught by practicum method with 95% feedback which is very high.Learning with using practical methods with feedback on the electrolyte and non-electrolyte material of X class of MAS DU affecting about 47.4% on improving student learning outcomes.   Kata kunci: Metode Praktikum, Larutan Elektroli dan Non Elektrolit, Hasil Belajar, Respon  Siswa, Feedback.
