The
American Journal of Physics publishes papers that meet the needs and intellectual interests of college and university physics teachers and students...
Contributions should treat subjects of value and interest to physics teachers and students. They should significantly aid the learning of physics and not be primarily a display of cleverness and erudition. Highly specialized contributions are not encouraged...
The Journal is particularly interested in manuscripts that can be used to bring contemporary research in physics and related fields into the classroom. Such manuscripts should not be review articles, but rather self-contained articles that describe a particular piece of research in such a way that it is accessible to as many physicists as possible...
Manuscripts announcing new theoretical or experimental results, or manuscripts questioning well-established and successful theories, are not acceptable and should be submitted to an archival research journal for evaluation by specialists...

The PER Section of AJP stopped accepting manuscripts on February 1, 2018.
http://web.mit.edu/rhprice/www/PER.html said:
The American Journal of Physics is discontinuing its Physical Education Research Section after processing all manuscripts now in the system, manuscripts submitted before February 2018.
This was announced in the editorial by PER Section editor Michael Wittmann and Editor Richard Price in the January 2018 issue of AJP. In that editorial it was pointed out that AJP will continute to accept papers on physics teaching.

* If the paper is more about methodology and statistics than about the question being asked, then it is probably inappropriate as a regular article. In many, perhaps most papers on teaching there must be a description of the methodology so this, of course is acceptable. If a major part of the paper is methodology, however, it is probably inappropriate as a regular article. For a regular paper, the details of methodolgy can be included as supplementary material, so that interested readers have access to all details.
* Does the paper use terms that may not (yet?) be familiar to the typical AJP reader though the terms are common in PER circles (e.g., scaffolding, metacognitive)? If so, the terms can be defined in the article. If the article becomes heavy with such special terms, it may be a sign that the article is not suited as an AJP regular paper.
* PER includes studies of theoretical issues that are not strongly linked to near-term applicability to teaching. Judgment must be used here. If the issue is sufficiently interesting, it might be interesting to the general AJP readership. If it is primarily interesting only to those in the PER community, then it is probably not appropriate as an AJP paper.
