Ring of Technologies is a beautiful visual wheel that displays a host of learning goals together with some examples of web tools to achieve them. To me this work (created and shared by UAF eLearning Faculty Resources) represents the core of digitally-based learning. It also chimes in with what we have said about purposeful use of technology in instruction. Having clear goals about what you want to target in your teaching using technology will definitely help your learners make the best of that technology.
This wheel is also available for free download in PDF format from this link.
