Abstract
This paper reports on collaborative learning as one of the most widely researched of all teaching methods in general and special education according to research. It discusses the benefits and difficulties of adopting this method in the Curricula in Greece and the United Kingdom (UK), and some comparative perspectives. The study of international literature was considered appropriate for the exploration of the topic. The ultimate aim is to provide greater opportunities for learning and socio-emotional development in terms of the following aspects: the benefits of implementing CL, the role of the teacher, the problems encountered and the purposes of CL. Through the research, it appeared that collaborative learning is one of the most valuable and fruitful areas of theory, research and practice in education. The purpose of this article, then, is to make it clear that cooperative learning exists when all students, both typical students and students with special educational needs, work together to achieve common learning goals (Johnson & Johnson, 1999). Each student can then achieve his or her learning goal if other group members achieve their (Johnson & Johnson, 1999).

Abstract
The operation of new electrical transformer cables is based on the principle of induction of electromotive force in an electrical conductor surrounded by a magnetic circuit. With the new arrangement of winding (or windings) in the form of cable conductors with a jacket, together performing the functions of the magnetic and protective parts of the transformer, the electrical transformer cable performs two functions: an electrical transformer and an electrical cable. In this case, the cost of a dual-use transformer cable is only the cost of one transformer or the cost of one shielded cable, which in this case is the same thing. The materials that make up the transformer are dual–use: one material is used both to perform the functions of the magnetic core and to perform the functions of the protective sheath (jacket) of the cable. As a result, combined shells–magnetic cores can be made from the same material with sufficient mechanical and magnetic properties.
Абстрактный
Работа новых электротрансформаторных кабелей основана на принципе индукции электродвижущей силы в электрическом проводнике, окруженном магнитопроводом. При новом расположении обмотки (или обмоток) в виде жил кабеля с оболочкой, выполняющих совместно функции магнитной и защитной частей трансформатора, электротрансформаторный кабель выполняет две функции: электрического трансформатора и электрического кабеля. В этом случае стоимость трансформаторного кабеля двойного назначения равна только стоимости одного трансформатора или стоимости одного экранированного кабеля, что в данном случае одно и то же. Материалы, из которых состоит трансформатор, имеют двойное назначение: один материал используется как для выполнения функций магнитопровода, так и для выполнения функций защитной оболочки (куртки) кабеля. В результате комбинированные оболочки-магнитопроводы могут быть изготовлены из одного и того же материала с достаточными механическими и магнитными свойствами.
