THE COOPERATIVE COURSE IN 

 ELECTRICAL ENGINEERING AT 

 THE MASSACHUSETTS INSTI- 

 TUTE OF TECHNOLOGY 



For the past year the Massachusetts Insti- 

 tute of Technology and the General Electric 

 Company have conducted a cooperative course 

 in electrical engineering', which has proved 

 unusually successful. In this course, a log- 

 ical working out of the underlying principles 

 has led to several interesting innovations in 

 the conduct of the work. In brief the scheme 

 is as follows : 



The course covers a total of five years, the 

 first two being identical with the regular 

 course in electrical engineering at the insti- 

 tute, the last three being divided between in- 

 struction in theory at the institute and prac- 

 tise at the Lynn works of the General Electric 

 Company. The instruction at the institute 

 during the first four years of the cooperative 

 course is similar in method and content to the 

 general course in electrical engineering at the 

 institute with certain omissions and abridg- 

 ments for which equivalents are provided at 

 the works. The work of the final or fifth 

 year comprises postgraduate research work 

 and training in design. Training at the 

 works is also conducted with a primary riew 

 to its educational value and is closely corre- 

 lated with the instruction in theory. During 

 the final year of this course considerable lati- 

 tude may be exercised by the students in the 

 selection of their line of work, assignments 

 being made either to shop management in the 

 works' office or to research in the company's 

 research laboratories, depending upon the 

 aptitudes and preferences of the individual 

 students. 



The schedule of the cooperative years, i. e., 

 the last three years, is as follows : 



The year (12 months) is divided into four 

 three-month periods, the students spending
