Encouraging motivation for
scientific work of high school students on an example the study of the magnetic
characteristics of solids
One of the major drawbacks of
the training of future professionals in higher education is an inert training
programs, and often a formality of the educational process, including quality
requirements for the execution of certain tasks. It is no secret that the
success of the training depends largely on the ability of the teacher to awaken
the interest of students and their enthusiasm not only to the subject matter
(specific task), but also to seek additional information regarding the studied
section of a particular academic discipline. And each teacher according to his
vision of material and assessment of learning problems with non-homogeneous
student audience chooses the best ways of presenting the material in the
circumstances.
It should be noted that
non-formal teachers' attitude to their duties causes a similar one of students
to the study, which significantly increases the level of education, and the
process of learning becomes for all participants much more attractive form.
One way of increasing the
interest of the student audience in an independent study of the discipline is
to hold seminars. Moreover, it is desirable that students be involved not only
in the preparation of materials, but at least in some measure have the choice
of the theme of seminars – of course, within the studied section. In other
words, the teacher sets the general outline of a class, and the students
determine the order of presentation and the nuances of the individual parts of
the studied problem.
The teacher is desirable to
maximize the creative impulse to manifest the students, giving them an
opportunity to show not only the ability to express the essence of the issue,
analyse the material, draw conclusions, and the like, but also to experience as
much as possible to a greater extent responsible for conducting classes, i.e.
feel is not so much an object of study as equal (to the extent possible) the
subject of the creative learning process. As a rule, such an organization of
the learning process of mastering the material results increase significantly.
As an example, the study of
the magnetic characteristics of solids within disciplines such as physics of
magnetic phenomena, or solid-state physics.
Students always perceived with
interest the information in the first place, is a bright and clear, and
secondly, on the verge of interdisciplinary connections. One of the objects
traditionally causes a surge of interest in the classroom is, for example, levitron.
Levitron – a gyroscope, which
rotates, is able to "hang" in the air on a special basis, forming a
magnetic cushion. As in the untwisted state, magnetic top weight of about 20
grams is able to hang on a special system of permanent magnets arranged in a
box (as the permanent magnets, levitron does not require a source of electrical
current). Gyroscope is a permanent magnet ring with an axis perpendicular
through the center of symmetry. The magnet in the box usually also the ring but
of larger diameter. The shape of the magnetic field caused by a combination of
these two sizes. Above the center of a large magnet at a certain distance of a
potential well is formed, there is a small area in the center of the magnetic
field which is somewhat weaker than the edges. It does not deviate from the
center of the gyroscope base. The size of this zone is determined by weight,
the magnetic field of the top, and the place where the phenomenon is possible.
Rotation is necessary to top not overturned. The moment of inertia of a
rotating body, according to the law of conservation of angular momentum holds a
top position in the repulsive pole down. Gyroscope is experiencing friction
force only air, so that it can float for a long time.
Levitron is a classic example
illustrating the laws studied usually within different disciplines. In this
case, it combines the knowledge gained in the study of mechanics and physics of
magnetic phenomena. Moreover, students with pleasure and enthusiasm made itself
a working model of the Levitron and together with the teacher get the pleasure
of seeing with their own hands created the current demonstration of greatness
and nontrivial laws of nature.
It is one of the examples of
creative students' interest in participating actively in the learning process.
Ideally, the whole process of learning should be built on such a creative
participation. It is clear that a fundamental part of the learning process is
more routine and not always so bright and attractive, but the teacher always
has the ability to "dilute" lectures one such training, supporting
students' interest in studying the discipline. The key here is the feedback
through the "teacher – student", and the teacher must be able to
respond to the "fatigue" student audience from routine material,
which in turn requires a good contact and trust between students and teachers.
In any case, respect for the teacher to the students and finding innovative
ways of presenting the material always finds a response and, as a rule, leads
eventually to a serious increase in both student performance and their social
and communication skills.
It should be noted that the
successful mastery of teaching material, supported by a creative approach to
learning is the key to further professional growth of students and stimulates
their interest in research and innovative solutions.
