In a JiTT classroom students construct the same content as in a passive lecture with two important added benefits. First, having completed the web assignment very recently, they enter the classroom ready to actively engage in the activities. Secondly, they have a feeling of ownership since the interactive lesson is based on their own wording and understanding of the relevant issues.
The give and take in the classroom suggests future WarmUp questions that will reflect the mood and the level of expertise in the class at hand. In this way the feedback loop is closed with the students having played a major part in the endeavor.
