In this study, we instructed uncertainty analysis focused laboratory course. The course was consist of five steps. At first step, we checked students' conceptual state about measurement uncertainty by some paper based questionaries and interview. At second step, we taught them concepts about measurement uncertainty by theoretical lecture. And then, we had an interview with students. We recognized that theoretical lecture was not enough to them to learn and understand measurement uncertainty. So, we divided one class into several groups. we had each group execute measuring gravitational acceleration by various methods. And each group compared their result and other's results. Finally we interviewed students to find their changes in laboratory work and attitudes to experiment. We concluded that some activity of comparing measurement results could help students understand measurement uncertainty and improve students' attitude to experiment.
