I have asserted in a variety of places that an important way to structure "learning objects" and ultimately to structure content on the web for use in multiple learning environments is through the use of questions. Today I bumped into a wonderful little quote that I will use in the future whenever I begin conversations about why questions are useful in learning.
"Questions are the door to human wonder" (p. 23). Harvey, S. (1998). Nonfiction matters. York, ME: Stenhouse.
This is a nice way to begin a discussion that questions are at the foundation of learning and when we start with the questions that a learner begins with we can take them through a maze of knowledge in an interesting and useful way that begins to link information to deeper and deeper knowledge and richer questions, but it always seems like the first place to begin instruction is with the learner's own questions.
