The Research On Mechanical Vibrations And Mechanical Concept Teaching Of Senior High School

Physics concepts area summary and description of the aracteristics of Physical phenomenon and attributes.They are the basis and important part of Physics.The teaching of Physics concepts is a very important part of Physics teaching in Senior Middle School.And the research into Physics concepts in Senior Middle School has become an important subject of Physics teaching research at home and abroad.Mechanical vibrations and mechanical wave as important knowledge in physics, it is not only the key content but also difficult content in the teaching. The mechanical vibrations and the mechanical wave are"the compound concept", because of containing the numerous child concepts themselves , also applies mechanics and kinematics many concepts and the knowledge synthesis in which, simultaneously in mechanics, electromagnetic wave, acoustics, even atomic and in the quantum theory also has the widespread application. Therefore the mechanical vibrations and mechanical wave this part need the teacher to carry on the science effective concept teaching.The essay is founded on the former achievements and guided by constructivism Pedagogic,cognition.In light of our country the concept of teaching middle school physical existence of the problem, combined with my years of teaching practice, research and analysis through the concept of a combination of empirical research, the concept of theoretical research and the concept of combining teaching and research methods, mechanical vibration and mechanical wave concept in detail research and comparison. In the study of mechanical vibration and mechanical waves based on the concept of the method by investigating the test before the students grasp the concept of understanding the situation, carry out the concept of instructional design, and post-test students investigate the concept of teaching, and finally made to stand the test of practice, teachers to facilitate the operation of the concept of teaching strategies.
