抄録

Some new contents of physics experiment were developed for the university students with the aim of paramedical study. These students are apt to have less experiences of science experiments and don't feel at ease with science. They are not good at handling scientific equipment also. Several devices are necessary for these students to be interested in physics and science. Some tools which are familiar for their diary lives were expected to play an important role to attract their interests to physics experiments. Wii stick game controller (NINTENDOU) that has a three-dimensional acceleration sensor within and is popular among young students were adopted to this purpose. The Doppler shift of the sound,emitted from a source in uniform circular motion,were observed by this Wii stick controller and sound monitor FFTWAVE, FFT soft wear. Process, required in this experiment,were elementary and the observed Doppler shifts were consistent with calculated values. Our ideas are expected to induce student's interests to physics and advance deeper understanding.
