Welcome to my webpage. My name is Osama Swidan. Since 2010, I have been a Ph.D. candidate under the supervision of Prof. Michal Yerushalmy and have been conducting research at the University of Haifa in Israel. My research interests involve examining learning processes of the integral concept with dynamic and interactive technological tools. My focus in my research project is on the accumulation process involved in the integration of a single-variable function. Observing the work of  high-school calculus students who had not yet learned any other integral-related ideas, I analyzed the emergence of the semiotic relationship between personal and mathematical meanings, as expressed through the understanding of mathematical signs in integration tasks. Especially, my research project aimed at analyzing the objectification processes related to the concept of integration when it is learned with interactive and dynamic technological tools among high school students. Further, I focus on design aspects of dynamic and interactive technological tools and its influence on the learning process. I focus on the roles played by directly dragging and graph-manipulation on the objectification processes of integral ideas. Recently, I developed an interest on curricular aspects of teaching and learning to advance calculus concepts with interactive and dynamic tools. Essentially, I focus on the learning trajectories that sprout as a result of using interactive and dynamic tools.
