I regard Wikipedia, Wiktionary and Wikimedia as being ideal places to start independent learning. Creative thinking is not mandated for students studying via Wikipedia. They do not have to create their own curricula. Many people are making portals on Wikipedia which act as surrogate curricula. However, by design, Wikipedia do not include exercises and provide feedback. This is where real teachers are still needed.
You hint at the need to first teach students to be critical readers, as there will always be residual errors even in encyclopedias. At all times, students need to reconcile what they are reading with what they have already read, and their own experiences and common sense. They should first understand https://en.wikipedia.org/wiki/Critical_thinking
There are other wikis that students can join in to share findings and creatively and constructively insert content such as URLs, bookmarks, annotated bookmarks, creative writing, still and video photography, sound recordings etc.
The blog or discussion tool can be used to engage students in exciting debates in which they have to think critically about their opponents' contributions in making up their rebuttals.

Critical thinking should NOT be thought of as an ability, but rather as a PROCESS.
It entails comparing and contrasting two things (such as a current situation with a previous situation, or two sets of research findings) and then reaching conclusions or insights based on the compare/contrast analysis. Interaction with peers can help this PROCESS.
A public wiki on the relevant subject may provide information in which to base the compare/contrast analysis. Your own internal wiki may help students synergize their ideas.
