Abstract:
This study aims to develop a topical subjects studied at secondary level, part of the curriculum theme Physical discipline. Expanding notions on linear harmonic oscillator to the field of the real oscillations is a challenge, but also a necessity. It is known that most natural phenomena are periodic phenomena. Therefore it is necessary to know the behaviour of physical systems in terms of disturbance of equilibrium states. Physical models used to the theoretically and experimentally study characterize the real world with a good approximation. But any physical model has its limits. In these circumstances, the extension will increase the stringency of the experimental activities of training teachers. Framework of teaching laboratory experiment combining in a balanced way both theoretical content, as well as experimental. Pedagogical strategies for extending the physical laboratory experiment considering gradually increase the degree of difficulty of the topic, but handling it in a different way. The student groups interested in the study of physics may be grouped and arranged some physics experiments. In this regard, to determine the same physical parameters, experimental methods can diversify. Also, use the computer at certain times of training leads to higher quality physical laboratory experiment. We estimate that the method of extending the concepts in physics and differential treatment in their laboratory experiment facilitates learning and initiate cooperation between students. These factors develop competition who generating performance among high school students.
