Many research shows that students have difficulties in understanding definition of definite integration. Therefore, the research is interested in designing classroom activities integrated with design research method to help students gain better understanding. In order to support students, realistic mathematics approach was chosen. Series of instructional activities had been designed to reach mathematical goal by using geogebra software. First year university students were chosen to implement the classroom activities. The results indicate that geogebra software help student gain better understanding to the definition of definite integral by providing dynamic visualization of the sum of inscribed and circumscribed polygon. © 2019 IOP Publishing Ltd.
