The scale of vibration is expressed by such measures as the acceleration and seismic intensity. However, it is not realistic for those who have no experiential sense for the scale of vibration. The intuitive feel of vibration helps to foster motivation to learn such the subjects as the earthquake disaster prevention, vibration and earthquake resistance in the department of civil engineering and the architecture. This paper introduces the portable shaking experiment device which is developed as a teaching material to support the intuitive understanding of the scale of vibration such as acceleration and seismic intensity as well as Fourier spectrum. The data of vibration recorded by the accelerometers installed at the shaking table and structure model are processed immediately and the wave form, maximum acceleration, seismic intensity and Fourier spectra are shown in real time. The effectiveness of the proposed experiment device is discussed by the questionnaire survey.
