I gave up with CK12. Well, to be more specific, I gave up trying to use it for 7th and 8th grade algebra and geometry classes. We are still using it for a 6th grade class, but more as a supplementary text and resource rather than as a primary textbook.
- The CK12 content is simply too inconsistent to use. There are just too many content errors to sort through and fix. Perhaps, much of it is fine for a conceptual based class where accuracy is secondary, but I cannot abide that. In addition, there are too many content gaps. If I am going to be left writing entire sections to fill in important details (equations with no solution, or special solution sets for compound inequalities), then what’s the point. I will probably point to some CK12 content for supplementary practice, but that’s about it.
- The only way to track student practice and progress with practice is to create assignments. That is a laborious process if I want to set up more than one or two practice assignments. Perhaps, I don’t want to set them with fixed dates? The official word is that it jeopardizes student privacy. I don’t see how. If I create accounts, and the students use those accounts, who else has access? Why shouldn’t I be able to see any of the progress my students make with any practice. This is where IXL gets it right.
