Pédagogie pour le prof de français
The European teacher magazine FDLM (webpage) is for FSL (and Immersion) teachers. Each print issue covers a range of themes and offers suggestions and resources for Core French teachers. (Both the website and magazine are written in French.) Even if you don't subscribe to the complete magazine, you can still read the first 14 pages or so of each issue via the issuu site and pick up some useful tips and resources.
