The CREST+ model, a model for writing effective online discussion questions, covers the cognitive nature of the question, the reading basis, any experiential possibility, style and type of question, and finally ways to structure a good question.  This model encourages students to participate in online forum discussions, provides a template for new online faculty to use in creating effective discussion questions, and promotes a higher level processing of the material.

The CREST+ model covers the cognitive nature of the question [C], the reading basis [R], any experiential [E] possibility, style and type of question [ST] , and finally ways to structure a good question [+]. 

<p> In discussing the need for hands-on science learning, Nichols asked us to imagine parents at the dinner table asking their young son or daughter that age-old question "What did you learn in school today?" The child shrugs, as children often do, and says, "We learned to play basketball." The parents then ask, "How did you do that?" The child answers, "Well, we sat in the gym and the teacher passed out these books, and we turned to chapter one, about passing the basketball, and we learned there are three types of passes: the bounce pass, the chest pass, and the one-handed pass." </p> <p> "OK," parents would say, wanting to know more, "what happened next?" The child continues, "We read the next chapter about dribbling. And another chapter on shooting. We learned there’s the set shot, the bank shot, and the jump shot." After a few minutes of this recitation, the parents, increasingly exasperated, challenge their child: "But did the teacher ever give you a basketball and let you go on the court and play?" "No,” the child says with a sigh. "We just read the book until the bell rang."</p>

<p>Perhaps the most fundamental property of a constructivist learning environment is that it offers a context for student learning. </p> <p>Context-embedded learning has been a cornerstone of the constructivist movement since the early 1900’s. Now, nearly a century later, video games and simulations can offer new contexts for student learning that would not have been available to students in the past.</p>
