Differentiation - Another method of Learning and Instruction

We can write the best manuals in the world but the Facilitator still needs to have some structure in the classroom, and the Facilitator Guide can help a great deal here. I have been doing some research on various manners in which knowledge can be permanently transferred to adult learners. I came across Differentiated Instruction and looked into it. Some of the principles are known in our SA environment.

Although this methodology is used in the GET band,  I wonder if it cannot be used in Adult learning?  (one of the tools are learning menus, and are a really amazing manner in which content can be taught) Differentiated Instruction is a method that has been introduced into US Schools.  Differentiated instruction and assessment (also known as differentiated learning or, in education, simply, differentiation) is a framework or philosophy for effective teaching that involves providing different students with different avenues to learning (often in the same classroom) in terms of: acquiring content; processing, constructing, or making sense of ideas; and developing teaching materials and assessment measures so that all students within a classroom can learn effectively, regardless of differences in ability ( wiki explanation more here - https://en.wikipedia.org/wiki/Differentiated_instruction )

 I am not going to repeat the entire web site or the concepts here, take a read in the articles below. The video is also worth the watch even though it is aimed at GET Schools. I would love to know your thoughts on this type of implementation in the classrooms. Has anyone implemented the Learning menus specifically?
