Abstraction is one of the methods for learning knowledge with using mental processes that cannot be obtained through experiment and observation. RBC model that is based on abstraction in the process of creating knowledge is directly related to mental processes. In this study, the RBC model is used for the high school students' processes of constructing momentum concept that were examined in an appropriate learning environment. Application was carried out with two volunteer tenth grade high school students. Two problems enabling the students to use their experiences and prior knowledge were designed and respectively used in the instruction. Observation, document review, and interviews were used as qualitative data collection methods. As a result, at the end of the implementation problems, it was observed that the students benefited from their prior knowledge in constructing new knowledge and they could construct momentum concept.
