FAQ

About the FlexBook Platform®

In a nutshell, what are the new features of the FlexBook Platform® 2.0?
  • Content formatted into concepts, smaller bites of information
  • A concept map for self-directed or educator-directed sequencing of concepts
  • Automatically generated eReader formats for distribution (formats for Kindle, iPad, NOOK and other Android devices)
  • Improved content layout for PDFs, HTML, and ePub formats

  • Sleek, clean user interface (UI)
  • Exercise Generator and downloadable worksheets
  • Account sign-in via Google, Facebook and Twitter
  • Document versioning - we now support easier creation of specific editions of a work to be shared or saved for reference.
What is a concept?
  • In the FlexBook Platform® 2.0, we have deconstructed our old FlexBooks into small lessons on a specific topic. These mini-lessons are what we are now calling concepts. On our old system, the breakdown went from FlexBooks to chapters. We have taken that process a step further and broken chapters into concepts. We believe this greater granularity will make it easier for teachers to find and curate the necessary content they need to organize and deliver their lesson and for students to seek and focus on the specific topics necessary to progress through a subject.
What is a concept map and how do I use it?
  • The concept map illustrates the relationships between concepts. This map is meant to provide a path for learners by guiding them though a sequence of concepts. While CK-12 will provide a default concept map aligned to various state standards, educators and learners will be able to create a customized map for their own needs.
What is a FlexBook® textbook?
  • CK-12's FlexBook® textbooks are open-source digital textbooks that are:
    • Free
    • Fully customizable
    • The current FlexBook® library primarily contains titles in science, technology, engineering, and mathematics. Users may read, download, and adapt CK-12's textbooks at no cost.
How do I get started with the new system?
  • The quick start guide below provides an introduction to the new system and describes how to view, search, and customize our content.

How does a student log in to complete goal?
  • If you have enrolled students using the roster method.Your students will use the username that appears under the student's information in your class roster section, and the password that you set for them when you created their accounts. This method automatically enrolls the student in your class.
  • If your students created accounts on their own, they will join your class using the "Class Code". After the student logs in, they will click the "Join a class" button and enter the class code. They are now enrolled in your class.
  • Here is an article that outlines these two steps: goo.gl/GXEqG
  • There is not really a supported way to print a roster with usernames and passwords, as we do not show the actual password. The best way to keep track is to create a roster using a csv. You will create three columns for last name, first name, and password that you upload to braingenie. This way you can refer to the spreadsheet if your students forget their passwords.

Using the CK-12 website

My chapters are not numbered the same in my pdf as online?

This is as designed, for printing an individual chapter. What you can do to preserve the numbering is download the book in it's entirety, and then split the pdf for the range of pages that you want. You should be able to do this using your pdf viewer on your computer; you will need to do save as or use a print to pdf option and select the ranges that you are interested in.

You can also do this using chrome and firefox is very similar.

Equations are not displaying properly on my e-reader (i.e Kindle,Nook).

This is because our equations are transparent images, so they will not display well on a black background. You can adjust the background color on the e-reader such as Kindle to white to make the equations readable.

Save, or display issues?

If you are seeing a "cannot save, 500 error message, internal server error", when trying to save. Or content is not loading, or appears blank.

  1. First try clearing your cache and browser cookies.

  1. Also, if you are running an anti-virus software this could be causing you some trouble. One thing that we recently noticed is that some anti-virus software blocks some of our content. Please check with your anti-virus provider to see if you are able to add ck12.org to their white list.

What do Basic, At Grade, and Advanced mean?

Achievement Level descriptions for Basic, At Grade, Advanced:

Basic: Students matched to this level have partial mastery of prerequisite knowledge and skills fundamental for proficient work.

At Grade (Proficient): Students matched to this level have demonstrated competency over challenging subject matter, including subject-matter knowledge, application of such knowledge to real-world situations, and analytical skills appropriate to the subject matter.

Advanced: Students matched to this level are ready for material that requires superior performance and mastery.

Collaborating on a Flexbook

There are a few suggested ways for collaborating.

1) You can create concepts using Google docs and then upload these docs into our system and into your book. Google docs has built in collaboration features that will easily allow multiple users to work on a single document. You can also use a Microsoft word document, if working offline.

** Our editor only supports a limited subset of both Google docs and Microsoft word formatting features, so you may need to make adjustments using our editor after uploading to get the desired formatting.

2) Teachers could work under a single account. This method does not allow multiple editors to work on a concept at the same time, because modifications would be overwritten by each other. You could divide the workload so that each teacher is working on a separate chapter, then you will not have to worry about overwriting each others work.

** As long as teachers are not working on the same concept this method will work fine.

3) Everyone has their own accounts and they work on separate parts of the book. When complete you can send the link to the resource to the one person who organizes the entire collection.

One thing to note is that every time you save a change to a resource, a new revision is made. So if teachers are working in their own accounts and sharing links to their work, they will have to send a new link every time they make changes. This is where working under a single account would be easier to manage not having to worry about using the most up to date resource.

You can create a group which will allow you to easily share resources between, collaborators. The link below has instructions from our FAQ:

http://www.ck12.org/about/faq/what-are-groups-how-do-i-use-them/

How do I change the cover art of my flexbook?

To change the cover of your book, you will need to go to the table of contents of your flexbook and click edit. Once the page loads you will be able to edit the cover image and upload your own.

How can I add exercises to my flexbook?

You can only contribute exercises to resources that belong to CK-12. Once you modify a chapter it becomes your own, and the exercise tab will no longer be exposed. If you wanted to add these types of exercises you could do so by embedding them into your pages.

To embed the exercises in your book click on the "Tools" icon shown with the exercise and grab the embed code. You can then use the embed code to embed the exercise, the same way you would embed a video.

How do I highlight and take notes in a flexbook?

While viewing a page in a flexbook, you can choose to highlight a section of text or make a stickie note. To do this click on either the highlighter or note icon floating by the right edge of the flexbook page. Now you can click and drag to highlight or leave a note for a section of the text. You can change colors for both items by clicking on the arrow next to the respective icon.

Note: All annotations and highlights will remain on the book for that specific version and are only visible by you. It is best to make a copy of the resource, that way your notes will always be easily accessible to you from your library.

How do I print a PDF copy?
  • You can download a pdf version of a reading, by clicking on PDF in the download section.
  • This feature will be located on the left hand side of the screen, along with other options like "Add to Flexbook" and "Make a Copy".
Trouble signing in? Accessing the site?

Here are a couple of things to try that might help:

  1. Try clearing your Browser's cookies for our domain ck12.org.

  1. Try clearing your Browser's cache.

What are groups? How do I use them?
  • The group option allows you to easily share resources with members of your group. When you share a resource with your group they will receive an email notification with a link to that resource.
  • The groups feature does not allow you to view the progress of your students.
To create a group:
  • Under the profile menu click on "My Groups"
  • Click "Create Group"
  • Enter a Group name and a group description
  • Click Create.
So others can join your group: Instructions that you can send to others:
  •  Create an account or sign in to CK12.org
  •  In the menu that appears when you mouse over your name, click on "My Groups"
  • Click the join group button and enter the group name "<Your Group Name>" and the access code "<Your Group Code>"
  • Once you click the "Join" button, the group should now appear in your list of groups.
Sharing content with group members:
  • To share content with your group members, you will have to click on the groups icon (two heads) and choose the group(s) you want to share with.
  • The groups icon will be under the "Share" section, along with the twitter, facebook, and email icons.
“Cannot save because an artifact of this name already exists” error message

This error means that there is an existing artifact that exists in the library with the same name. This is probably happening because at some time the artifact was saved and added to your library.

You can open another tab in your browser, go to your library and rename the duplicate resource. Or you can open the existing resource and make your changes there.

 
“Cannot save because a newer version exists” error message

If more than one person is working on the same book or concept, every time you save your changes you create a new version of that resource. As that resource is being updated simultaneously by the other editors, other versions are in turn becoming outdated.

The best way to avoid these conflicts is to either author the book, chapters and/or concepts independently and then add them to a book once it is ready, or use Google docs or Microsoft word to author chapters/concepts and then import the files into a single flexbook. You can also import a Google collection to create a flexbook.

How do I add Sections (concepts) to my chapter?
Here are the steps for adding a concept to your chapter:
  •  This assumes you already have concepts that you want to combine into a chapter. Please see our tutorial video on how to create a concept. http://www.ck12.org/about/ck-12-learning-center/
  • Click "edit", from the table of contents.
  • Create a new chapter or click on the green arrow next to the chapter title to expand an existing chapter.
  •  Drag concepts into the chapter using the rearrange icon ( 3 horizontal lines).
  • Save your work.
  • Chapters are like buckets that you can use to group related concepts into. A chapter will have a green arrow to the left fo the chapter's numbered order.
  • Concepts are where the main content of the chapter will go, think of them like the subchapter when in the context of a chapter. They can be grouped together under a chapter, or standalone within a flexbook.
  • When in doubt, create a concept. If you find that you have several relating concepts it may be helpful to group them under a chapter.
Can I recoup the cost of printing a FlexBook from my students?
You may make a hard copy available to a student and recoup the cost of printing the book, as long as your student knows :
  • they may obtain a free version of the book online (on the CK-12 website),
  • the copying costs are nominal
  • the book is used for educational purposes
  • there is no profit motivation
  • the book will be used in accordance with the other provisions of our license
A learning institution or individual may print a small amount of copies (less than 1000 copies), in order to distribute to their students.  We extend this courtesy to our users and our only requirement is this:  Please email support@ck12.org and advise us of the following:
  • Who are you?
  • What learning institution do you represent?
  • How may we contact, if needed?
  • How many copies do you wish to print, of which book?
  • How will he material be used?

What is the difference between “share” and “publish” in my CK-12 account?

In your CK-12 account there are several ways to disseminate information, including sharing links via email, posting links on Facebook and Twitter, or downloading in these file formats: PDF, Mobi for Kindle, or ePub for Droid and iPad.

However, there is a difference between "Sharing" content and "Publishing" it. If you "Share" a resource with another, it is by "invitation-only" and the recipient must be logged into their own CK-12 account in order to view it. This is a great way to broadcast interesting material to a private group of users easily.

"Publishing" is making your content available to the world - it becomes "public". When you publish a resource, you are giving everyone access to view it or download in one of the support formats (ePub, PDF). Public content is searchable and discoverable by other users interested in that topic.

How do I Publish my FlexBook and/or concept?
First sign into your account. If you do not have an account you can create one here: sign up. Also please be aware of the differences of sharing and publishing on our system. Publishing your FlexBook:
  • Go to the "My Content" tab in your library.
  • Click on the title you want to publish, this will take you to the table of contents.
  • On the left hand side click on the "Publish" link

  • Next fill out the Publish Request form and click submit.
 
  • You will receive notification once your FlexBook has been published.
  Publishing your Concept:
  • Go to the "My Content" tab in your library.
  • Change the "Filter by Type" setting from FlexBooks to Concepts.
  • Click on the title you want to publish, this will take you to the concept.
  • On the left hand side click on the "Publish" link
 
  • Next fill out the Publish Request form and click submit.
  • You will receive notification once your FlexBook has been published.
How do I “share” My Content?
Sharing content in by "invitation only," and is immediate.

There are several ways to share content using CK-12's FlexBook Platform®. You can email a student a live link, called a URL,  to your FlexBook.   You can email them a PDF file (the best format for printed versions). You can post a link to your content in Twitter or Facebook. Or you can download a file, and share it with users of Kindle, iPad, and ePub devices.

First, sign into your CK-12 account.  Click on "My Content" and the title of the FlexBook or Concept you wish to share. Once the resource opens, you can grab the URL at the top of the page, copy it, and paste it into an email to students. You can post it in your LMS, or post it on Twitter or Facebook.  Please note: recipients can only view shared content once they are logged into their CK-12 account, unless the content is "Published.

To download and share a PDF file, Kindle/Mobi file, iPad/ePub file, then click on "My Content" , open the title you wish to share, select "Download/PDF" (or Download Kindle, or Download iPad) from the left side of the screen. The system will either download the file immediately, or will email you a link to access the file.  Open the file and save it to your hard drive.  To upload the file to a mobile device, please follow the device manufacturers instructions or see our FAQ section dedicated to this subject.  Once saved to your hard drive, one may email the file as an attachment to students.  Please note: recipients can only view shared content once they are logged into their CK-12 account, unless the content is "Published".
What is the difference between Share and Publish?
The main differences between sharing and publishing content is access and exclusivity.

Shared content is viewable only within one's CK-12 account, is by  "Invitation only", and is immediate.

Published content is viewable to anyone, outside of a CK-12 account, is searchable using key words by anyone, and there is a short delay in publishing (as publishing requests are reviewed by real humans).

      3. After the files are finished transferring to the NOOK and BEFORE unplugging the USB cable, you must eject the device from the computer. Removing the USB cable before doing this can cause harm to your eBooks and/or the NOOK. Simply right-click on the NOOK drive and select the undock, eject, or unmount option.

What about the Content?

Can I recoup the cost of printing a FlexBook from my students?
You may make a hard copy available to a student and recoup the cost of printing the book, as long as your student knows :
  • they may obtain a free version of the book online (on the CK-12 website),
  • the copying costs are nominal
  • the book is used for educational purposes
  • there is no profit motivation
  • the book will be used in accordance with the other provisions of our license
A learning institution or individual may print a small amount of copies (less than 1000 copies), in order to distribute to their students.  We extend this courtesy to our users and our only requirement is this:  Please email support@ck12.org and advise us of the following:
  • Who are you?
  • What learning institution do you represent?
  • How may we contact, if needed?
  • How many copies do you wish to print, of which book?
  • How will he material be used?
  • What price do you intend to charge for these books?
What is the difference between “share” and “publish” in my CK-12 account?

In your CK-12 account there are several ways to disseminate information, including sharing links via email, posting links on Facebook and Twitter, or downloading in these file formats: PDF, Mobi for Kindle, or ePub for Droid and iPad.

However, there is a difference between "Sharing" content and "Publishing" it. If you "Share" a resource with another, it is by "invitation-only" and the recipient must be logged into their own CK-12 account in order to view it. This is a great way to broadcast interesting material to a private group of users easily.

"Publishing" is making your content available to the world - it becomes "public". When you publish a resource, you are giving everyone access to view it or download in one of the support formats (ePub, PDF). Public content is searchable and discoverable by other users interested in that topic.

What type of materials can I find on the FlexBook® site?
  • The CK-12 FlexBook® library currently includes STEM (science, technology, education, and mathematics) curriculum for grades 6-12. Additionally, there are SAT Preparation materials, English books, and more! The library is growing all the time. We have plans to develop many more resources, and one day will offer a comprehensive curriculum for grades K-12.
What other resources does CK-12 Foundation offer?
  • We operate three educational websites:
    1. www.ck12.org - which hosts our online textbooks, and the FlexBook® Platform for creating textbooks
    2. http://ineedapencil.ck12.org - website where students may practice and prepare for the SAT exam
    3. http://flexmath.ck12.org/ -  website that provides a complete Algebra I curriculum and lesson plans, as well as drills to help students review core math skills
How many books are in the CK-12 system?
  • Our library currently contains over 80 textbooks with many more on the way. Right now, our seeded library is almost exclusively focused on STEM material for middle-school and high-school students. But we expect this library to grow -- and ultimately encompass all subjects for K-12 -- as teachers and authors create books and donate them to the CK-12 public library.
  • Our users have created over 11,000 FlexBook® textbooks to date and more are created each day!
Does the material adhere to state and national standards for K-12 textbooks?
The quality of our seeded FlexBook® textbooks is very high. Our public repository contains materials which have been developed in step with national, state, and Common Core standards, when possible. All of our seeded textbooks are reviewed by subject-matter experts to ensure they adhere to those standards. Click here to see how our books align to various standards.
Can I view the standards?
  • Yes! Click here to see how our books align to various standards.
Do the textbooks include practice exercises and quizzes/exams?
  • Yes! In general, practice exercises appear in most of our core Student Editions following the lesson.
Who wrote the textbooks that CK-12 gives away?
  • The CK-12 FlexBook® textbooks are written by K-12 subject-matter experts and teachers. We make sure that all of our seeded materials conform to national, state, and Common Core K-12 standards and guidelines, when possible. In addition, all of our books are edited and reviewed by K-12 practitioners who write or teach in the subject.

Who is the author of my textbook?
  • If you are editing/adapting a textbook seeded by CK-12, then the authors we contracted to write the book remain the "authors" in the attribution, and you would become the "contributor". If you write the bulk of the textbook, and our seeded material is only a small portion of that content or none at all, then you are the "author" and the original author becomes the "contributor". Please email support@ck12.org for clarification if needed.

How do I request permission to use an image from outside of the CK-12 Foundation?
  • In these cases, we are a licensee of the image, and have been granted the use of the image either under CC-BY-NC-SA, or some other stated license.

How many schools are using FlexBook® textbooks?
  • Hundreds of schools across the Unites States and globally, both public and private, have implemented CK-12 FlexBook® textbooks in their curriculum.
When will you have K-5 materials?
  • CK-12 aims to be a comprehensive source of teaching materials for grades K-12. We are currently focused on middle school and high school STEM subject material, and hope to add K-5 materials in the future.
How does a FlexBook® textbook differ from a collection of Wikipedia articles?
  • CK-12's textbooks are focused on teaching materials for Kindergarten through 12th grade. Our books conform to state, national and Common Core standards for K-12 textbooks, when available. We also offer materials such as Lesson Objectives, Vocabulary, and Q&A -- similar to the ancillary materials found in traditional textbooks.
Is the software that supports the FlexBook Platform® open-source as well?
  • No. The CK-12 FlexBook® system is not an open-source project.
Will materials from the major publishers be available on your site?
  • This is currently not a part of CK-12's goal. Our textbooks and other materials are copyright-free and unless publishers change the licensing of their materials, it won't be feasible to incorporate their material into our site.
What other delivery formats do you offer for FlexBook® textbooks?
  • CK-12 is pioneering the next generation textbook. We offer an alternative to the expensive, heavy, obsolete traditional textbook. Our content is fully flexible. It is high-quality, and may be delivered in many formats including PDF, ePub, HTML, and MOBI (Kindle).
What is the cost to print a FlexBook® textbook?
  • This depends on you. You may print a book in part or in whole. Your printing costs will depend on how you choose to print your FlexBook®: at home, at school, or at a print shop, in black and white or in color, with or without binding and covers. One of the lowest cost options is to print what you want in black and white, on three-hole punch paper, and put it in a binder.
Do I have to print the book or can I view it online?
  • You do not have to print the book and may view it entirely online. Our site will host your book online and you can simply view it using your web browser. You may also save it as a PDF and view it on your computer without internet access.
Can you get me actual books?
  • Today, you may print a FlexBook® textbook on your personal printer at home, school, or print shop.
I’m interested in donating a textbook I’ve written. How do I go about it?

    • Your work must be original or not bound by another copyright.
    • You will be required to sign our donation letter.

Who is CK-12?

What does the ‘C’ in CK-12 stand for?

The C has an open meaning, in the same sense that our platform is open. It stands for content, classroom, customizable, connections, collaboration, I might be missing a few but the idea is that our content can be used by anyone anywhere for free.

It originally meant "Connect"... since CK-12 was to be the missing connection between K-12 education.

Why focus on K-12? Why not all of education, especially higher education?
There are already other open-source higher education programs like Connexions, Sophia, and Merlot, but currently not enough focus on K-12. CK-12 intends to fill that gap.
Who will use this site? Are there any limitations on who can use this service?
Anyone can use this site; there are no limitations on who may access our services and materials.
What distinguishes CK-12 from other web-based education projects?
CK-12's FlexBook® textbooks are unique in that we aim to provide a comprehensive K-12 online curriculum that conforms to curriculum standards. We currently develop content for science, technology, engineering, and math (STEM) textbooks. Our FlexBook® system is the only free web-based application for adapting open-source material and creating customized textbooks.
How is CK-12 funded?
  • CK-12 is generously funded by the Amar Foundation, and by Vinod and Neeru Khosla, who have a profound belief that everyone deserves the opportunity to learn.
What is the cost of using CK-12′s FlexBook® textbooks?
CK-12's websites and textbooks are available free of charge. You can view them online with your browser, or use them with a PDF reader. If you choose to print a FlexBook ® textbook, you simply pay the printing costs.
What is the goal of CK-12?
CK-12 Foundation's goal is to provide high-quality education materials to all, so that everyone has an opportunity to learn.
Who is CK-12?
CK-12 Foundation is a non-profit with a mission... produce free & open source K-12 materials aligned to state curriculum standards customized for students and/or teachers' needs.
