Terms of Use and our Privacy Policy.
HippoCampus.org is a free, core academic website that delivers rich, multimedia content—videos, animations, and simulations—on general education subjects. As an open resource for personalized learning, HippoCampus.org was designed to improve access to quality education for everyone, and is powered by The NROC Project (NROC), a nonprofit organization that collaborates with secondary, postsecondary, and adult education leaders to improve student readiness, persistence, and success. NROC makes editorial and engineering investments to maintain HippoCampus.org.
We are a non-profit organization and provide the content at our websites for self-improvement only as part of our mission. You cannot get credit for it since we are not a school.
You can email a comment or question directly to nroc.org/contact, or you can click the "Comments and Questions" icon in the Media Window control bar. The icon looks like a small speech bubble.
While we understand that you may need assistance with your homework, we cannot provide the answers to your problems or individual assistance. We hope you can use our website as a tool to help you learn the subject matter so that you can find the answers.
More than half the use of HippoCampus occurs during classroom hours, when teachers go online to project topic lectures and show simulations launched from the HippoCampus site.
HippoCampus is not a credit-granting organization, and does not monitor, grade, or give transcripts to anyone using the site. However, many home schooling families have used HippoCampus content to supplement or guide their home curriculum, and we welcome them as users.
HippoCampus is made possible by the members of The NROC Project, and many NROC members offer credit for courses that contain HippoCampus content.
Yes, although homeschoolers should realize that the content presented is not a complete course. The content is intended to have an instructor to provide supplemental assignments and instruction. Since there is no teacher available through HippoCampus, the parent must take the role of instructor.
No. Our Terms of Use specify that HippoCampus is provided by The NROC Project for personal enrichment and individual instructor use only. The unlicensed use of this content by educational organizations or commercial vendors is prohibited.
Unfortunately, there is no way to download the video from our website. As an individual user, however, you may create a custom HippoCampus page and then link to an individual topic. After you have created your custom page, there will be buttons in the upper right corner that allow you to view the text version (when available), bookmark, or link to the topic.
Yes, in multiple ways. First, there is a "maximize" button beneath the bottom left corner of the Media Window which will widen the screen. There is also a "hide column" button beneath the first column of content in the Browse Topics tab. These can be used simultaneously or independently. For some content, such as that from Khan Academy, a small button in the lower right corner of the media control bar allows the content to be shown full screen. For other content, such as Algebra I--An Open Course, right-clicking the mouse over the video content will open a menu that offers Full Screen as an option.
Your screen resolution may be set too low. The Algebra course requires that your screen resolution be at 1024x768 or higher. Most of the other content requires a resolution of 600x800 or higher.
Much, but not all, of the content at HippoCampus is closed captioned.
Section 508 of the Rehabilitation Act to requires Federal agencies to make their electronic and information technology accessible to people with disabilities. The law applies to all Federal agencies when they develop, procure, maintain, or use electronic and information technology. The educational resources provided at HippoCampus.org were not procured by, and are not made available through, a Federal agency, so the law is not applicable to the content at this website.
All the content we provide at HippoCampus is created by other educational institutions and companies and contributed to us to distribute as part of our non-profit mission.
Due to the complexity of modifying the multimedia content, we cannot always correct errors within the video presentations. There is an Errata icon that appears with any topics in which a known error has been identified. We encourage our users to report any errors they discover so that we can notify everyone of the problem.
There is also an errata sheet available for some courses if you select "Launch a Full Course."
Use the "Comments and Questions" feature in the Media Window control bar. The icon looks like a small speech bubble, and allows you to send in a description of the error directly from the relevant piece of media. Or you can send an email to nroc.org/contact.
Please describe the issue as precisely as possible.
If you provide your email address, we will inform you about the correction process, or ask any follow-up questions necessary to clarify the report.
The tests that appear on our website are intended as open tests for self-assessment only. They are not intended to be secure tests since the answers are freely available at several websites.
There are answer keys available for the chapter tests but not for the review questions. The answer keys for the chapter tests are located as a link right under the chapter test link.
We know a lot of homeschoolers use HippoCampus. We are often asked if homeschoolers can study the content at HippoCampus and then just take and pass the AP exam.
HippoCampus courses were designed to address the AP College Board criteria. However, as with any teaching resource, they should not be considered a singular solution, but can be used as a good foundation for an AP teaching curriculum. The courses at HippoCampus have not currently been mapped to the CLEP and DANTE tests.
If you wish to receive college credit for taking an AP course, most colleges will require that the courses have been approved by the College Board. Schools wishing to give their students AP credit must go through the AP audit process. The same is true for homeschoolers. The AP Course Ledger section below gives more information about the audit process.
AP Course Ledger
The AP Course Ledger is a comprehensive and public registry of all courses authorized to use the AP label on student transcripts. The Ledger is an annual and culminating product of the AP Course Audit, a process by which college faculty confirm that courses submitted by AP teachers and schools provide students with the essential elements of a college level experience. As an exclusively Web-based registry, the Ledger is published annually in November and updated weekly throughout the academic year to reflect newly authorized courses.
Here is a link to AP Audit information, (and you can find other links on this page to various other resources):
Yes, the AP Course Audit is only required for schools desiring to:
-- use the "AP" designation on students' transcripts
-- be listed in the ledger of authorized AP courses provided each fall to college and university admissions offices and the public.
Schools that simply offer the AP Exam as an opportunity for their students to earn college credit, without actually labeling the school's courses "AP" on students' transcripts, do not need to participate in the AP Course Audit, and can continue offering AP Exams to their students.
Our AP content is a good resource to help students prepare for AP exams. However, while we provide content resources, we do not have instructors who teach the courses. In order to be authorized by the College Board and put in the AP Course Ledger, an instructor must submit a syllabus for the course. While we do not have instructors who teach our courses, we do have NROC member schools that teach the courses for credit and they have been approved through the AP College Board.
