• Unsurprising. I mentioned this on EEng's talk before ([1]). Ultimately STEM isn't learned by reading and our articles are written very technically and asan encyclopaedic reference rather than as a learning resource. ProcrastinatingReader (talk) 21:22, 28 December 2021 (UTC)Reply[reply]

• Our math and physics articles are a mix of garbled verbiage and verbal garbage, the apparent need to write in an impenetrable style instead of maybe using the English language is painful. It comes off to me as an intentional effort to show off instead of inform. To cite an obvious example, there are plenty of YouTube videos that explain Graham's number in a reasonably approachable manner (the man himself does it here, for instance), yet our article is an incomprehensible orgy of hypertechnical terms that quickly make me want to go full Oedipus on my eyes when I even attempt to read it. Linguistics articles can get like that too, for sure, but while a little clicking around is usually good enough to get through those I would never read Wikipedia to learn something about mathematics that I didn't already thoroughly understand; from that, I rather think the problem is self-evident.

  Well, BotNL (hey -- you should have a bot called BotNLBot), as Andrew Gleason put it:

  It is notoriously difficult to convey the proper impression of the frontiers of mathematics to nonspecialists. Ultimately the difficulty stems from the fact that mathematics is an easier subject than the other sciences. Consequently, many of the important primary problems of the subject‍—‌that is, problems which can be understood by an intelligent outsider‍—‌have either been solved or carried to a point where an indirect approach is clearly required. The great bulk of pure mathematical research is concerned with secondary, tertiary, or higher-order problem, the very statement of which can hardly be understood until one has mastered a great deal of technical mathematics.

  I'm sorry, but Graham's Youtube chat may give you a warm feeling that you're learned something, but in fact you haven't. The purpose of our articles is to lend real understanding to those who have something like the background, not to let readers pretend they've learned something. That's what Youtube videos are for.

  I have to say, one of the very few reasonably well-written articles on this is 0.999.... Instead of going out of its way to instantly assault readers with every possible esoteric term imaginable, and a few that aren't, it presents the subject in a very straightforward manner and uses easily approachable examples to demonstrate its point. This is, as the article itself notes, a very counterintuitive bit of math, so clearly it can be done. I get that most other subjects aren't the abject crank magnets that article is, and I suspect that external pressure is why, almost alone, that article is written in such a way that it eschews navel-gazing gobbledygook in favor of language that actively encourages understanding. The Blade of the Northern Lights (話して下さい) 06:19, 31 December 2021 (UTC)Reply[reply]

  To the contrary, 0.999... is mostly unsourced, and much of it looks like the sort of sophomoric filler one gets from writers who don't have a firm enough grasp of the subject to make any clear point but still need to reach a long enough page count. —David Eppstein (talk) 08:27, 31 December 2021 (UTC)Reply[reply]

  I thought the lead was at least worth a read, I came away understanding more than when I went in. Also, since that article is under perpetual siege, I can see where its development is stunted. The Blade of the Northern Lights (話して下さい) 15:56, 31 December 2021 (UTC)Reply[reply]

• A sometimes applied doctrine says it's okay to be an insider to an academic discipline, writing an article, but we must remember our audience is outsiders. Alas, it seems many articles are written for insiders by insiders, or at least they try to teach the things every insider must know. If we are failing to address the audience properly, maybe we should include prominent links to tutorial videos, such as those of Khan Academy, when good ones exist. My efforts at trying to understand why stars pulsate, for example, have been more advanced by YouTube than by Wikipedia. WP assumes I know a lot about transparency of ionized gases, which actually fits me somewhat well, but also about enthalpy and other gas thermodynamic questions, which are a deep mystery to me. Such things tend to be addressed to grad students of the appropriate major and, umm, I never came close to graduating, nor did a course in optics or gas dynamics. If it were just astrophysics; no big deal but most our STEM areas are like that. Jim.henderson (talk) 00:15, 29 December 2021 (UTC)Reply[reply]

• The audience for Wikipedia isn't just "outsiders". Sometimes, the same article has to serve multiple purposes, because anyone might read it — from schoolchildren to professional mathematicians. This is why we have the "write one level down" and "put the easiest part up front" guidelines. And if we tried to write a hand-holding introduction to every subject that presumed half of a high-school education, we'd need more than one of each. No one introduction works for all readers. The same textbook can come across as friendly to one reader and gimmicky to another. Please the former, and you'll lose the latter. We'd also face WP:NPOV and WP:NOR problems. To write a textbook-style introduction, you need to pick how to begin and what to include, devise a path through the ideas, probably invent examples that haven't been used anywhere else before... Wikipedia, as a platform, simply isn't equipped to do any of that. As a physicist who has written expository material for students, research papers for colleagues, and Wikipedia articles, I can tell you that the process and the mindset are necessarily different for each one. XOR'easter (talk) 05:07, 29 December 2021 (UTC)Reply[reply]

  Moreover, the editors who are subject-matter experts and who have managed to adapt themselves to the different requirements of writing here are either working away in obscure corners because that's where their enthusiasm leads them, or they're run ragged trying to clean up fringe nonsense, vanity-fueled autobiographies that try to use Wikipedia as LinkedIn, schlock added by well-meaning editors suckered by sensationalist pop-science and churnalism... There just aren't enough volunteers to go around. For years, I've seen complaints about the difficulty of our technical articles, and sooner or later that thread of anti-intellectualism always works its way in. "Ha ha, I was never good at math, lolz, I stopped reading at the first word I didn't get, let's pivot to video." There's no consideration for the intrinsic difficulty of the subject, or the challenge of writing about it, or the human element of finding people qualified to do so when all the incentives are for them to be doing work that advances their careers. I've been trying to make it work for years now, and I'm tired. And I'm done. XOR'easter (talk) 07:25, 29 December 2021 (UTC)Reply[reply]

  @XOR'easter: - I've resigned myself to mostly focusing on minor WikiGnome cleanup work for mostly this reason. I do use Wikipedia to hoover up articles in my area of interest that cover concepts I didn't know existed, and I'm fortunate that most of my watchlist is low-interest and low-traffic work, but if I attempted to conduct the Big Big Rewrites that Definitely Need To Happen, I'd wear myself thin. I still find value in the addition of accessibility templates - language templates, using ((ubl)) and ((pb)) in place of line breaks - but it's definitely not the heavy-hitting stuff I used to do. I feel sorry for people working in more active areas of interest - I can't begin to imagine the nightmare of attempting to wrangle more than five high-importance, high-traffic articles at once.--Ineffablebookkeeper (talk) (((ping)) me!) 16:02, 18 January 2022 (UTC)Reply[reply]

• Of course we should always take what we can learn from this kind of exercise. In particular, we could make better use of the "Introduction to..." format to serve a wider range of audiences.

• The Oxford English Dictionary tells us that the original meaning of encylopedia (ἐγκύκλιος παιδεία) is ‘encyclical education’, meaning "the circle of arts and sciences considered by the Greeks as essential to a liberal education." The first definition that follows this is "The circle of learning; a general course of instruction."^[1] If a credible source judges the bulk of Wikipedia unsuitable for opportunistic learning by college undergraduates, then we have a serious problem.

• One of the standards of WP is that each article is to be focused on its topic, and make major use of bluelinks with only brief statements about what they contain, rather than have an article be anything like a self-contained exposition on the whole topic. It's not a school essay, or a single page to learn an advanced concept if one doesn't have the foggiest idea of the field of study as a basis. I think the intro section, besides defining the topic in an accessible fashion, lets one know whether one has any sort of background or context to be able to understand much of the rest. We do have a ton of articles on introductory topics and introductory articles on some advanced topics, but as the study rightly points out, we also have lots of non-introductory articles on non-introductory topics. And, as others have noted, some topics really are fairly impenetrable by their nature, due to niche article scope. The problem might not be that "any given article isn't fully accessible for self-learning to anyone with no background", but rather that we don't have at least some article on each major or lay-accessible topic that is. Depending on one's starting point (article, and personal background), that might be a few clicks down a rabbit-hole, and require a major investment to get up to speed.

• In "Mathematics", "articles were generally instructive from an encyclopedic viewpoint, but the fluid narrative was less useful for learners unless supplemented". While there were no accuracy concerns, "C-qualifiers were frequently applied because the development was less helpful for opportunistic learning". Accords with my experience, not just of Wikipedia, but of university textbooks, lecture notes and tutorials. Higher education maths pedagogy is horrific. I have had a small number of excellent teachers, lecture notes and truly fantastic textbooks (Information Theory, Inference, and Learning Algorithms, if anyone's looking for some light bedtime reading). However, for the most part, mathematics writing is done by a lot of thinking and scribbling and playing with toy examples, coming to some abstract conclusions, and then writing down the abstract conclusions and erasing all evidence of the toy examples, forcing the reader to rediscover those for themselves if they want to actually understand why something is true. During university, I regularly had the experience that a correct answer I had given to a problem sheet question was impenetrable to me just three days later.
  The problem for Wikipedia, then, is that making articles understandable necessarily makes them unverifiable, because mathematical papers and even textbooks and lecture notes do not give any or enough illustrative examples to learn the concept, or spell out the finer points that would be immediately obvious to anyone with the education to be reading the source. — Bilorv (talk) 11:56, 30 December 2021 (UTC)Reply[reply]

  For real. And at any rate, this "it's not useful for learners unless supplemented" conclusion is... describing exactly what an encyclopedia should be, anyway. An encyclopedia is a reference work! Its use as a pedagogical tool is secondary. I know students are reading it, and that's a very good reason (among many others) to care about whether or not our articles are accurate.

• @The Blade of the Northern Lights: - I'd second the comment about linguistics articles - and I'd also point out that densely-written articles that take on an essay-like tone cause problems for editors who aren't even attempting to rewrite the article's content itself. It can be difficult to know what to fix or even if the addition of certain templates will cause problems if the article is too dense to work on.

• I'd be more interested in a study of how STEM students (and others) actually use Wikipedia, rather than some educators speculation on how useful it ought to be. I certainly would have found it very helpful when I was in school. Back then we were taught to write terms and concepts we didn't understand on index cards and spend time in the library looking them up. How quaint that seems today. Of course search engines could be used if Wikipedia did not exist, but Wikipedia provides more organized, hyperlinked and sourced presentations. One thing that would be interesting to know is how often students start their inquires on Wikipedia rather than a general search. Wikipedia is often one of the top search results in any case. And yes, our articles leave room for improvement. They always will.--agr (talk) 17:58, 4 January 2022 (UTC)Reply[reply]

• Pouncing on brief summary statements in the lead without looking at the cited paragraphs (and sources) that they summarize is always going to throw up ambiguities – all natural language is ambiguous and metaphoric, basta. If "opportunistic learning" means never going beyond the lead section – because the rest of the article is – what? Too long ("Too many notes, Herr Mozart")? Too difficult? Too picky with defined terms, careful citations, attributions to scientists? – then opportunistic readers are self-condemned to read only the lead, and maybe flick through the pictures, glance at the captions.
