Bleg: Web hosting for my version of a logic textbook.

I want to create a simple webpage to promote a version of a free logic textbook that I have been working on. Basically, I want to have a dedicated website to host the .pdf file for the text, the LaTeX source file, some text promoting the virtues of the book and open access textbooks in general, supporting textbook materials, and maybe some tools for collaboration. And I should have an easy to remember URL.

I was thinking that Wordpress would be the easiest software to use. What should I do for hosting? Pick the cheapest host that partners with Wordpress? Will there be much of a learning curve with Wordpress?

The last time I created a website was almost 10 years ago, and I just wrote something in HTML and transferred it to some host using FTP software. Can you still build websites like that?

My Holiday Writing Project: Smashing Perverse Insentives

My goal this break is to revise For All x, a logic textbook made available free under a Creative Commons license, so that it is appropriate for my community college students. Textbook prices are salt in the wounds of students who have trouble paying from college, but right now teachers have no pressing reason to assign cheap or free textbooks, since they don't have to pay for them. (The economists call this kind of situation a "perverse incentive.") Most free logic books are written for geeks by geeks and aren't useful for the sort of student who is hurt most by textbook prices, so I think my project will help more than just my students.

I'm already running into problems, though. The changes I want to make are fairly basic: I want to rearrange the order the material is presented in so that more of the basic stuff comes first, and then I want to create more exercises for that basic material. (I'm just calling my version of this text a "remix.") But simply moving around text is turning out to be difficult. Magnus wrote the whole thing in LaTeX, which I don't know, so I've been opening the files in MS Word, replacing the formatting tags with formatting in Word, and then making the alterations I want to make. I was then going to convert the whole thing to a .pdf and send it to Kinko's to create $3 coursepacks for my students. Getting all the formatting straight is a big pain, though. Which leads to questions

Should I just learn LaTeX? Can I do this over the break and get the text ready in time for my stduents? Is there a reader I should use to show how the marked up text will appear in print? How do I put this all in a form that Kinko's will accept?

If I don't learn LaTeX right now, how do I get my formatting to look like Magnus's? How can I figure out what fonts he is using given the LaTex files or a .pdf file? If I'm just approximating his formatting, what fonts should I use?

These are just my initial worries. I haven't even begun to do things like generate new exercises yet. I'm still hung up on the mechanics of producing a book. Anyone have advice?

Open Access Logic Textbooks

I've decided that my students should not have to pay for a logic textbook. Most textbooks are obscenely expensive., but logic textbooks in particular get in my craw. The formal systems that they teach have been a part of the human intellectual heritage for over a hundred years, and the textbooks don't do anything in particular to make more approachable for students. They survive on the laziness of instructors, not on any originality content or presentation

So logic is going to be the first class that I teach to use a free, open access textbook. But which one? Changing textbooks is hard. For a long time I used Hurley at SLU I switched to Barwise and Etchemendy, but I never quite adapted to it, and since it was too sophisticated for LCCC students, I've gone back to Hurley. But Hurley is crazy expensive at $155. So what to do?

Here is my first very quick survey

blogic, by David Velleman: Respected author, looks like a nice approach, but seems to be pitched at the same level as Barwise and Etchemendy. Also, there doesn't seem to be a download or print version available.

For All x: Covers all and only the standard topics with the standard approach. It looks like I could take this on without seriously changing the preps from my Hurley course. Available as .pdf or as a print-on-demand book from Lulu. The author says that when he teaches it, he simply takes the book to the copy shop and has it printed as a coursepack. very nice.

Introduction to Logic Online interactive textbook. Would be nice if I were teaching online, but would be an adjustment from what I currently do. Covers all and only the topics I want to cover, though.


Introduction to Logic
A collection of modules from the Conections website of free course modules. Hard to adapt or for cc students to relate to. Tied to the Teachlogic website which looks mostly like it is about infusing logic into the computer science curriculum.

Formal Logic from wikibooks. Doesn't look approachable.

Heck, the Magnus book looks like just the item. That was quick. I wounder how quickly I can replace all my texts with open access books. There are some books, like Liszka's ethics text that I wouldn't want to replace, just because the book is so high quality. Munson's bioethics book is also very popular among students. My intro class right now relies on primary historical sources, which are generally available for free on line, but students have little problem shelling out $10 for the penguin version. I guess Critical Thinking should be next.

Some free logic software from Hatzic. Not sure how to work this in pedagogically.
