I have edited some questions to add country tags. Someone has removed them from at least one question. Let us talk about what are the best practices around country tags on Matheducators.
I think a country tag should be used when a question is about the educational system of a particular country. There might also be other cases, but I think this is the default one.
- Anything related to Common core (though there is already a common-core tag, which is more specific; I think it should usually be preferred if running out of tags for a question)
- What is the school system like in Syria?
- Why are the mathematics Pisa results much better here than there?
- What kind of help can I find for my dyscalculic child in Japan? (Hypothetical question, as far as I know.)
Is it a good and useful tag?
- It not a meta tag. The tag describes the content of the question. This is a desirable feature for a tag.
- It is fairly easy to determine when the tag is relevant. Would the question make sense when applied to any other country and still have the same answers? If so, it should not have the country tag. This is good, in that it is unlikely for there to be constant arguments about when to apply such a tag.
- Someone can be an expert in a country tag. Someone could be interested in following such a tag. These are both desirable properties.
- There are country tags on academia.SE and, as far as I know, they do not cause issues. Furthermore, the reasons are similar: educational systems vary. This is weak evidence that the tags might also be okay here.
- If ME had a higher volume, or when it will have, the tags would be useful for filtering out uninteresting questions or focusing on the interesting ones. I would, at least, be inclined to follow particular country tags (of my country of birth and country of residence and potential countries of residence), while the country tags with which I had but little connection or interest I might ignore.
I do not see any real problems, so these are weak. Please let me know of more serious problems and I will edit them in.
- The questions might be obscure and there might be nobody to answer them. This is not really a problem with the tags, and furthermore, difficult questions are okay on SE. Maybe the expert will eventually come by. Having the tag will make it more likely for them to find the hard questions.
- There would potentially be many such tags. I do not really see any problem here.
- Someone might jealously edit in a country tags to lots of old questions, thereby flooding the front page with old questions. This is not really a problem with any particular tag; usually, it is best practice to only edit a couple questions per day. (Personally, I am not bothered by old questions re-emerging, even en masse, but I understand some are.)
- The country tags might overwhelm other, more descriptive, tags. I do not think this is a problem at the moment, and when there are several applicable tags, one chooses those that are most relevant to the question. If the country tags are the most relevant, than they are, and if not, some others are.
