Is Lecture as a Dominant Form of Teaching Dying? by N. N. Gubanov, N. I. Gubanov

“…Nowadays, lecture is increasingly seen as an inefficient form of education, hopelessly outdated, with little interest and response among students, useless and, in principle, dying. The authors are firmly convinced that lecture was, continues to be and will be the main and indispensable form of instruction for the reproduction of an intellectual elite. …”

Low fluctuation stiffness design method for vibration reduction of helical gears by YOU Zhiwei, GAO Jingtao, LI Haonan

“…In order to improve the vibration characteristics of the helical gear system, a design method of low fluctuation mesh stiffness was proposed.MethodsSince the length of the contact line of the helical gear pair changes during the meshing process, resulting in mesh stiffness fluctuations, the core idea of the design method was to deduce the conditions for the minimum change of the total length of the contact line in the meshing process according to the mesh principle. Then it was compared with the finite element method to verify the correctness and effectiveness of the parameter design method and the analytical mesh stiffness model. …”

The impact of education system on economic growth by E. A. Tatarinova

“…In order for education not only to exist, but also to be at a decent level, remaining the basis for the development of economic potential and society, it is necessary to make science the base, the foundation of all changes. The principle of “managing education in a business-like, scientific way, without turning it into a business” has become the main one in the context of transforming the educational sector into a modern, innovative sphere, meeting the requirements and needs of the evolving digital time.…”
