I am an associate professor of physics[1] who believes that the Wikimedia Foundation can drastically reduce the cost of higher education by encouraging students to help develop instructional materials for most lower division courses. We need to put this kind of material on Wikiversity where people can freely use and modify: http://www.passmyexams.co.uk/index.html See also: https://www.osmosis.org/

##### The projects that occupy most of my time are:
1. Wright State University Lake Campus is where I currently teach all my courses. I teach mostly physics, with a bit of engineering, mathematics, and astronomy. Most of my courses are at the freshman/sophomore college level.
2. Quizbank is an attempt to create an open-source bank of exam questions. The internet already stores virtually all the text required for any degree in higher education. Wikitext is soon approaching that level of completeness. What's missing is a zero-cost method for individuals to verify that they have this knowledge.
3. https://wright.miraheze.org/wiki/Main_Page is a wikifarm node where where my students can write wikitext in private, for a grade. The privacy is needed so that students cannot "peek" into each other's efforts. The very best efforts can then be imported into Wikipedia/Wikiversity/Wikibooks/WikiJournal.
4. https://wikiversity.miraheze.org/wiki/Main_Page is another private Miraheze page that I use for sundry purposes (e.g. to prepare manuscripts for publications not licensed under Creative Commons.)

The rest of the page is a bit of a mess that I am too busy to clean up.

## To do

List of subpages
1. clean or delete file:Talk_WikiJournal_WikiJournal_User_Group_-_Wikiversity.pdf
2. Post: Двадцать пять лет он пережевывает чужие мысли о реализме, натурализме и всяком другом вздоре; двадцать пять лет читает и пишет о том, что умным давно уже известно, а для глупых неинтересно,— значит, двадцать пять лет переливает из пустого в порожнее.

11. Wikipedia: A Relativistic Trolley Paradox just in case it is deleted by Wikipedia. There is also something in my sandbox at Special:Permalink/1578330. June 14, 2016

One of the references shows how John Dalton might have used used nitrogen (N2) and oxygen gas (O2), as well as Nitrogen dioxide (N02), and nitrous oxide (N2O) to establish the indirect evidence that atoms exist. (They mix in simple ratios of volume, although it should be noted that it is not certain exactly how Dalton reached his conclusions).

Also created sevveral templates to help organize all this: Template:Subpages/Simple, Template:EduV, Template:EduV/tip,Template:EduV/announcement,Template:EduV/warning, and Template:EduV/generic-- December 25, 2015 Just before midnight (local time) on New Year's eve, gave quizzes editable subpages that can be created from the protected page.

23. Wikipedia and Wikiversity: Improved the appearance by making the same changes to both pages: Electrostatics (Wikipedia) and Coulomb's Law (Wikiversity) (where I also added a figure). Wikiversity and Physics equations are starting to merge as I use Wikiversity pages to compensate for the lack of calculus in openstax Physics. May 26, 2014

49. Wikiversity: Minor rewrite of second paragraph of lede to Wave particle duality. October 28, 2014 My edit experienced a make-over, but the experience was not at all frustrating because an editor and I both agreed that the original paragraph was flawed. A look at the Talk page will verify the nature of the positive synergy between our efforts. If only Wikipedia editing were always like this. Compare the easy and fun edit of Wave-particle duality with the effort several editors had to expend on a well-intentioned novice on the Talk page to wave packet

## Things I have learned about Wikiversity

The most important thing I have learned about Wikiversity is that it is underdeveloped. We need help! The goal is to set learning free by making learning resources easy for everybody to use, edit, and modify.

Personal journal of things I have learned
1. use File:EM_Spectrum_Properties_edit.svg
2. Set Preferences/Editing to that an opportunity to add a summary is offered if you attempt to save the page without one.
3. Wikiversity:Colloquium | request custodian action | Wikiversity:Import
4. CC-BY-NC-SA is more restrictive than Wikiversity's CC-BY-SA license. See Wikiversity:Non-Commercial_Tag_Issues. Posting CC-BY-NC-SA content can be done on Wikiversity but is problematical (see fine print)
5. Special:SpecialPages | Special:PrefixIndex | Help:Special_page | Special:DoubleRedirects | Special:PrefixIndex | Special:ListRedirects | Special:WhatLinksHere | MediaWiki:Deletereason-dropdown | Category:Candidates for speedy deletion | Category:Proposed deletions | Category:Requests for Deletion | Template:Protected_course
6. When using Inkscape (I was) using Inkscape flowed text, which isn't part of the SVG specification and doesn't work outside of Inkscape. In the Text menu there's a way to convert flowed text to standard SVG text. To create SVG text in the first place, just click on the canvas when creating it, rather than clicking and dragging. darkweasel94 17:49, 25 January 2014 (UTC) Writing symbols with Inkscape: Tex \ell is Brush Script MT or Freestyle Script or French Script MT; best is Mistral. Tex \mathcal R is Amienne bold or Bradley Hand ITC; best is Kristen ITC. Vladimir Script does both poorly.
7. Help:Wiki_markup | Help:Displaying a formula
8. w:User:Mark_viking has a cool website for editors. Lots of comment templates.
9. {{whc}} is a template for pages with little or no content.
10. To moves content while preserving page history, request at Wikiversity:RCA.

click to view or hide fine print on posting CC-BY-NC-SA

You currently can post CC-BY-NC-SA if you provide a non-free rationale ("fair use"). Such posting is advisable if resource is significant: There is no hazard to Wikiversity/Wikimedia Foundation from the hosting of NC material; however, a commercial re-user of the content won't have permission. Part of the policy requires that non-free content (e.g., NC) be machine-readably tagged. The non-free use rationale process is set up to create the tagging.

Commons, for images, will not host NC content. So if any NC content is needed here, it should be uploaded here and proper licensing -- and fair use rationale -- asserted ASAP. Sysops and others will assist you in that.

...you can use an archive-on-demand service if you are concerned that the content might disappear, such as http://archive.today, if it is not already archived on archive.org. (taken from a post by user:Abd)
