### Goals

Introduce ORCCA

An OER package of basic algebra materials.

Introduce PreTeXt

Software you can use to make textbooks.

ORCCA Algebra Textbook

WeBWorK Exercises

### ORCCA is an OER package

1. HTML: interactive, accessible, portable
2. Book: PDF or printed
3. online homework for “free”
4. (some) ancillary materials
(more coming next edition)
5. Braille and EPUB coming
(hopefully next edition)

### ORCCA HTML eBook Scavenger Hunt

Visit HTML Version:

spot.pcc.edu/math/orcca/ed2/html
Work in teams of 2–3 people to find an example of each:
• Lesson Objectives
• Embedded Videos
• SVG images
• Interactive Checkpoint Example
• Cross-Reference Knowl
(“click to reveal”)
• Solution Knowl
• GeoGebra graphing calculator
• Embedded GeoGebra applet
(Hint: section 1.1 or 1.3)
• Exercises
• Index
• Activate highlighting (challenge!)

# HTML eBook

# PDF and print

### PDF flavors

Black & White print, on Amazon

Printing logistics are a challenge.

Black & White PDF files

Part I, Part II, Part III, All of it.

# WeBWorK

### WeBWorK Integraion with ORCCA

ORCCA has over 6000 exercises. Most start life as a WeBWorK problem file.

problem file $$\to$$ one random version $$\to$$ official book version

problem files $$\to$$ WeBWorK problem sets that refer back to the book

Later we invite you to explore WeBWorK problems.

• Find a host server.
• Use MAA server, with a fee.
• Use Edfinity, with a fee.

ORCCA WeBWorK files available through ORCCA home site (pcc.edu/orcca).

### Highlights

• Access from day 1 (or earlier)
• Tailored to course objectives
• Videos and missed class
• Paper homework, WeBWorK, or both
• Cost
• Culturally responsive
• In the classroom, use the HTML version
• Videos and reading questions for online/hybrid/flipped

### Curriculum Redesign

\begin{equation*} \begin{array}{c}\text{ORCCA}\\\text{1st edition}\end{array} \implies \begin{array}{c}\text{freedom to redesign}\\\text{curriculum}\end{array} \implies \begin{array}{c}\text{ORCCA}\\\text{2nd edition}\end{array} \end{equation*}

Needed: a curriculum that better fit student needs.

• Cut topics
• Resequenced

Reinventing curriculum committee and book adoption processes is a challenge!

### Licensing

An OER needs an open license…but which one?

• Creative Commons BY? (our ultimate choice)
• Creative Commons BY-SA?
• Creative Commons BY-SA-NC?
• Creative Commons Something Else?
• Something Else?
Are we licensing the text/images/etc., or the source files and their coding?

### Student Data

There are challenges to gathering data scientifically. The data we have suggests no change (up or down) in success rates, possibly a reduction in withdrawal rates.

### Cost Savings

OER use at PCC is tracked and cost savings are estimated:

We estimate ORCCA currently saves PCC students about \$500,000 each year.

### Analytics

More than geography. Phones/tablets/laptops/desktops? Chrome/Firefox/Safari/Edge? Actually reading their textbooks?

### Coming in a Future Edition

• Worksheets
• Exams/Quizzes
• Slideshows
• Braille
• EPUB

# PreTeXt

pretextbook.org

Write structure, not styling:

                    <theorem>
<title>Fundamental Theorem of Calculus</title>
<statement>
<p>
This is a famous theorem:
<m>\frac{d}{dx} \int_a^x f(t)\, dt = f(x)</m>
</p>
</statement>
</theorem>


### Theorem: Fundamental Theorem of Calculus.

This is a famous theorem: $$\frac{d}{dx} \int_a^x f(t)\, dt = f(x)$$

### Multiple Output Forms

Now

• HTML (accessible, professional styling, generally works well on a small screen)
• PDF (professional styling)
• Jupyter Notebook

Under Development

• EPUB
• Braille
• Word worksheets
• Slideshows

# Collaboration Tools

### git

The Problems

• Up to eight people working simultaneously on the same project.
• Curriculum is always evolving. How to write a book and stay ahead of that?
• How/where to keep draft material that may or may not be ultimately used?
• How do we make it easy for other institutions to adapt to their needs?

### git

One Solution

git is free version control software.

• Work on same file(s) without checking in with each other.
• Rewind a project to an earlier state.
• Create a “branch” for experimentation.

• Internal authors' discussion of technology, pedagogy, style, etc.

• Invite discussion and review from colleagues.

Organized submission of issues: typos, errors, more substantial suggestions for improvement…

### Questions?

Thanks for learning about our book, ORCCA, and the software used to make it, PreTeXt!

##### WeBWorK Demonstration Shell.

These exercises match the book in structure, but with randomization.
