A system of physics simulation practice has been introduced in the introductory physics education of a College of Technology in Japan, in which students (age 19) can make their computer program by themselves including the numerical integration of equation of motion and the graphical presentation of the results. A graphic utility (MYGRPH) is developed to make the student programming in class unit (40 students) easy and interesting. The practice of student is designed to investigate the several phenomena by reproducing them in computer applying the related physical law and adapting the proper model for each phenomenon. The phenomena listed for the practice include the realistic one such as free fall under air resistance and the complicated one such as the non-linear pendulum showing chaos behavior. The example of a practice is shown for case of the falling rain drop with various radius, in which the inertial air resistance is found dominant for almost all radius from pouring to drizzling rain and the viscous drag is found effective only for misty rain. The educational effect of this practice system is discussed together with the description of student impressions and opinions in Appendix 1. The main part of the source code of MYGRAPH is given in Appendix 2.
