Open Resources for Community College Algebra (ORCCA)
Open Resources for Community College Algebra (ORCCA) is an opensource, openly licensed textbook package (eBook, print, and online homework) for basic and intermediate algebra. At Portland Community College, Part 1 is used in MTH 60, Part 2 is used in MTH 65, and Part 3 is used in MTH 95.
ORCCA is available as an interactive HTML eBook, a downloadable PDF, and a printed and bound physical book.

1st Edition 


Gamma Pilot Edition 


Beta Pilot Edition 


Alpha Pilot Edition 
Note: Copies of this book say edition beta, but they are really our edition alpha from before we had thought more about versioning. Also, this book’s cover is the color we use only for Part II. 
Sample schedules
The most common schedule at PCC for facetoface operation of these classes is ten weeks of class plus a final exam week. Fall term has an additional week of class. In summer, these courses are often (but not always) taught with 8 weeks of class and no finals week. Most classes run two days each week, but some run three. In every term, there are holidays, inservice days, and closures to contend with. So these sample calendars are not a perfect fit.

Selected exercise sets
A few members of the committee overseeing these courses (MTH 60, 65, 95 at PCC) came together and selected exercise sets that an instructor might adopt and feel comfortable that they provide adequate coverage. And of course, customize as wanted.
Most exercises are available as WeBWorK exercises, but not all, as indicated below. It is important to know this because if you rely on WeBWorK for homework, you would want to separately assign these exercises as “pencil and paper” exercises. The nonWeBWorK exercises are typically exercises where something needs to be graphed or explained, and automated grading by WeBWorK is not appropriate.
If you use WeBWorK, you may elect to load these “selected” exercise sets or load exercise sets with all WeBWorK exercises from each section. In either case, you may of course customize by adding, removing, or editing exercises.

Online homework
About 5600 of the roughly 7000 exercises in ORCCA are available as online exercises in WeBWorK.
WeBWorK is an opensource, free online homework platform. An institution can host its own WeBWorK server. An institution with its own WeBWorK server may be willing to host courses for faculty at other schools not having adequate IT resources. For a fee, the Mathematical Association of America will provide 6 months of access to a WeBWorK course. For a WeBWorK demonstration of ORCCA exercises (edition 2), see this demonstration course and log in as a guest.
If you are PCC faculty and are interested in using ORCCA together with WeBWorK for online homework, please see WeBWorK for faculty.
If you are not PCC faculty and you have access to a WeBWorK server, download the ORCCA WeBWork sets file and follow the instructions in the README file. The instructions assume that you have serverside command line access to the WeBWorK server.
Odd (and even) answers
For edition 2, the answers to oddnumbered exercises are here: ORCCA odd answers. If some answer is incorrect or missing, please report this using the feedback form below.
Edition 1 oddnumbered answers are also available, but there is no effort to correct errors and omissions.
We don’t publish even answers. The committee that oversees these courses has a majority opinion that they should not be published. Some faculty intentionally make use of the evennumbered exercises, knowing that there is no readily available answer guide. Since ORCCA generally has exercise parity (e.g. #19 and #20 are the same exercise with different random details) faculty who want published answers may assign oddnumbered exercises and not miss out on content covered in an evennumbered exercise.
Video playlists
The HTML version of ORCCA has a YouTube video playlist at the top of almost every section. These videos are not exactly a replacement for the written content, but they are meant to be a close approximation and are labeled “Alternative Video Lesson”. Meaning, an alternative to reading everything. You may want to use the playlists for other purposes, and here you may find the complete list of YouTube playlist IDs for edition 2.
https://www.youtube.com/playlist?list=PLmuZCPhWPtdqjDRbGl2sSeMeTvrHik4p
These may be used in many ways. The most common way would be to provide someone a link to go to YouTube and watch the playlist. That would be a URL with the following structure. Note the playlist ID is at the end.
https://www.youtube.com/embed/videoseries?list=PLmuZCPhWPtdqjDRbGl2sSeMeTvrHik4p
Another common need would be to embed the playlist in something else. For that, use a URL with the following structure. Note the playlist ID is at the end.

The videos feature PCC instructors working through examples on screen. You can download PDFs with these same examples, with space provided as in the videos. A common use for this is to ask students to complete these “video lecture notes” as they watch the videos. The Part 1 and Part 2 zip files include two large PDFs (one with module breakpoints for a tenweek course and one without) and also .tex files. The Part 3 zip file includes an individual PDF for each video lecture playlist.

Suggestions, observations, and other feedback
We welcome any feedback from all users. Especially feedback that is specific enough that we can act upon to improve the book. If you would like to register an observation (anything from a trivial typo to wanting a section entirely rewritten), please use the ORCCA Edition 2 feedback form.
Submissions are organized in a spreadsheet, and as volunteers have time, each submission is considered and acted upon in some way. Small things like a typo might be immediately corrected in the HTML eBook. Larger changes might be made, but need to wait until the next edition to be seen.
Background
In July 2016, PCC’s strategic planning initiative awarded funding for math faculty to produce a complete OER for precollege algebra. The book has a working title of ORCCA (Open Resources for Community College Algebra).
At PCC, these materials will cover the sequence MTH 60/65 (or its alternatives MTH 61/62/63 or MTH 70) and MTH 95. The textbook is being written using PreTeXt, which provides:
 An ebook, free to everyone
 A print book synchronized with the eBook, available for free as an electronic PDF, or for cost plus overhead at the PCC Bookstore
 Embedded online homework exercises using the online homework platform WeBWorK
Work began in the summer of 2016.
 The MTH 60 portion of the book was piloted by 11 PCC faculty in Fall 2017, 12 in Winter 2018, and 9 in Spring 2017.
 The MTH 65 portion of the book was piloted by 7 PCC faculty in Winter 2018, and 9 in Spring 2017.
 The MTH 95 portion of the book was piloted by 10 PCC faculty in Spring 2017.
Starting in the fall of 2018, all facetoface sections of MTH 60/65 will use ORCCA. Online sections may choose to use ORCCA or a specified commercial textbook. For MTH 95, all sections may choose to use ORCCA or a specified commercial textbook.
The content of the early editions is driven by PCC’s Course Content and Outcome Guides for these courses. The approach to the content is partly informed by the authors’ understanding of how this content is currently taught at PCC, and partly informed by published research on improving student success at these levels. We hope that over time, ORCCA replaces the CCOG in the sense that it becomes the CCOG. Committee work that has been put into CCOG development and textbook searches in the past will instead be put into making this book suit our needs.
Over academic year 201819, the PCC curriculum for these courses changed, and ORCCA changed along with them. This led to ORCCA’s edition 2.
