Abstract:
A traditional teaching method, that physics teacher are using in our days, is the lecture method. This means that teachers transmit in a passive way the knowledge to the students and for this reason the pupils are not active participants to the lesson. In order to motivate the students and to determine them to assume an active participation to the physics lessons, modern educational tools are used. The aim of this study is to illustrate periodical phenomena presented in an interactive way. The periodical phenomena could be seen in everyday life and in many fields of activity. Such examples are: the moon phases, the seasons changing, the heart beats the alternation of the breathing phenomena. The characteristic of a periodical phenomenon is its periodicity and the fact that during the evolutionary course there is at least one physical quantity associated with the system that varies between a maximum value and a minimum one. From the periodical phenomena the gravitational oscillations of the pendulum and heart beats were chosen to be illustrated, using the COBRA 3 system of acquisition and data processing provided by PHYWE Company (Germany) and Heart Rate Sensor connected at NOVA LINK (Fourier Education-USA). Passing from the compulsory courses presented in the syllabus to the examples from the real life this could make physics more attractive, gathering the interest and the behavior of the students regarding the subject.
