Abstract
This study aims to identify students^ misconceptions about rotational motion by using a four-tier diagnostic test. This research was a mix method research with sequential explanatory research design. The samples of this research were 26 Physics students of Universitas Negeri Malang who have taken Fundamental of Physics 1 course. We used simple random sampling technique. The instrument consist of 10 four-tier tests with four levels. Data analysis was carried out by grouping the results of the data obtained into four groups, including misconceptions (M), understanding concepts (UC), not understanding concepts (NUC) or errors (E). Besides that, interviews were also conducted to obtain more serious and in-depth information about the material that experiences the highest misconception. The highest misconception experienced by students in the concept of rolling motion as pure rotation is 53.84% with the category of high misconception. Based on the results of interviews with 3 students who indicated misconceptions about the concept of rolling motion as pure rotation, they were confused about comparing the angular velocity and linear velocity of two related wheels.
