Essential questions

Today i was reading about essential questions (chapter 5) and I felt that I do fall into some of the questioning traps that are mentioned, for instance, opening up with a really deep, profound question but not following up with activities that allow students to inquire the answers or similarly have many interesting questions but not having a clear intent. This meant that students were engaged in thinking about a topic but never really new why. One of my steps will be to start thinking about my current goals and objectives in terms of potential units and questions.
