Community reviews for CK-12

It is well grounded. It offers a variety options for teacher and students.

CK-12 is most useful for busy teachers with the insight, and motivation to produce their own multimedia enhanced textbooks but who do not have time to start from scratch. Though marketed directly to students, CK-12 functions best as digital library/laboratory for teachers to select, enhance, and compile modular content into books and courses that can be distributed on and offline. Like Wikipedia, the quantity and quality of these modular components varies considerably. Benefitting from millions in government and foundation support for STEM subjects, Science and Math resources are abundant, varied and of almost uniformly high quality. In contrast, the offerings in English and SAT exam prep are scarce and in the latter case, bear the marks of hasty development by inexperienced interns.

Here Ck-12 introduced the Flex Book, where you can create STEM flex book own your need you can edit books, update the information and you can share it. You can also create study group on the website and you can monitor how students are learning.

A nice set of interactive textbooks with images, links and video content. Works well on mobile devices. Can download the content in a variety of modes: PDF, ePub, ect Cons- as in all "textbooks" there is a great deal of reading. For math and science content only at this time

Being a teacher in a low-income community school, this website can serve as a textbook for my students, right at home. It helps students as a centralized resource that they can use to further their knowledge. I think it could be better if relevant Youtube links to videos were attached, for learners who prefer to understand the content in a more audio-visual manner.

While there are limited history resources on CK-12, the sources they have are valuable. I like that there are multiple formats to read including PDF (which is great as a teacher if I want to project on the SMART board), or the kids can download the book to their iPhone or tablet.

I use this website as a resource when I'm searching for background information on a particular topic. I would say that 80% of the things I've accessed have been of very high quality. Sometimes there are videos on there that an average YouTube.com search would not find. All of the videos have been vetted by other users, but that doesn't necessarily mean that they're great.
