Elements of Differentiated Teaching Physics at the Department of Physics MISIS. Experience of Identifying and Teaching Gifted Students
Methods for selecting and forms of working with gifted students of junior courses are suggested within the differentiated education course of physics.
Key words: differential education (teaching); competition in physics; two-level workshop; problematic task; gifted students.
There has been the novel theoretically innovative scientific-methodological approach to solitary work in general physics course considered. The methodological origin of the concept appears like multidimensional cellated geometric structure in which one can realize various educational trajectories of solitary work. The individual path has been chosen with student consciously in dependence on development of competence and the level of aspiration.
Key words: high school education, general physics course, educational standards, selftraining, continuous self-education.
Active learning at the methods of action basic turns self-learning action of students on physics into self-education, intellectual personal and communicative reflects of study process. Basics of methodical system of collective student’s works were written.
Key words: activity approach; Subjection; Learning problems of studying activity of students on physics; Collective unassisted work.
The content of notion “the event” in space-time models of classical and relativistic mechanics is considered. The traditional treating of the event in Special Relativity Theory (SRT) is shown to be essentially a classical one. The conception of similar (corresponding) events registered in different inertial frames in SRT is suggested.
Key words: special relativity theory (SRT); physical picture of world; space and time; space-time model; event; similar (corresponding) events; non-Euclidian geometry.
Mass in Special Relativity in General Physics Course
During the explanation special relativity we propose to use the conception of united mass, independent from velocity of its motion - the mass is invariant in all inertial systems, but has not additive property in velocities near velocity of light.
Key words: special relativity, conception of united mass.
Principal of Correspondence in Optics
Principal of correspondence is not only well-known early heuristic method of quantum theory, but a good teaching methodology tool. The use in optics are proposed in the context of both, Rytov’s polarization plane rotation, and energy flow localization using Poynting’s vector.
Key words: correspondence principal, polarization plane rotation, interference, energy
What is the Phase and what is the Polarization of Monochromatic Light Wave? New Conception of Elucidation of this Question in the Frame of Optics Course for Students of Physics Departments of Universities
It has been shown that the parameters, by means of which the polarization state of monochromatic electromagnetic wave is determined, can be found directly from the starting equations for vector of field without consideration of equation for polarization ellipse. The appropriate methodology is offered in which the finding of parameters determining polarization of monochromatic light wave precedes the derivation of equation for polarization ellipse.
Key words: polarization state, monochromatic light wave, polarization ellipse.
Theoretical and Experimental Studying Parametric Resonance in a Course of General Physics
In this article we consider the theory of parametric resonance and the condition of observation of this event hatches. FN experiment, allowing students to look after the event of parametric resonance, is also described.
Key words: pendulum, swing of pendulum, parametric resonance, swinging.
The possibility of using the method of electrolytic bath for the analysis of the electrostatic field geometry on the boundary of two dielectric media (the phenomenon of the field line’s refraction) is demonstrated and proved. The boundary is modeled by changing the depth of an electrolytic layer, through which the steady-state current flows, by forming a step-like bottom of the bath.
Key words: electrostatic field; electrolytic bath; step-like bottom; steady-state current; boundary of two dielectric media; refraction of the field lines.
The Laboratory Installation for Measuring the Speed of Light in Dielectrics
It’s created an experimental setup for measuring the speed of light in solid, liquid and gaseous dielectrics at room temperature on the basis of model laboratory equipment provided with by manufacturer PHYWE. A distinctive feature of the installation is to use a short (from 0.2 to 1.5 m) of the reference light beam, which allows you to put all the equipment on a standard laboratory bench.
Key words: speed of light; gaseous, liquid, solid dielectrics; Lissajous figures; phase; phase shifting; electromagnetic wave; refractive index; group and phase velocity of waves.
Investigation of Gas Discharge Plasma
The description of the laboratory work to study the plasma frequency discharge using a probe method and spectral analysis of plasma oscillations.
Key words: gas discharge, low temperature plasma, laboratory setup.
