Is there any journal in which I can publish educational articles not a research article? I want to publish an educational article about some non-standard approach to Lagrangian Mechanics, but the problem is that I have written it in my country language (not in English) so I want to know if there is any journal which accepts academical papers, I shall surely convert it into English if there exist one. I want to mention that I have no background in research, I'm a lecturer at one of the state Universities.
One example would be the American Journal of Physics published by the American Association of Physics Teachers. Quoting from their Audience and Mission statement (at the link above):

The mission of the American Journal of Physics (AJP) is to publish articles on the educational and cultural aspects of physics that are useful, interesting, and accessible to a diverse audience of physics students, educators, and researchers. Our audience generally reads outside their specialties to broaden their understanding of physics and to expand and enhance their pedagogical toolkits at the undergraduate and graduate levels.

They have quite a broad range of articles, many of which are of broad interest.
