This is a basic lesson plan for a children's handbell choir, taken from the sequence of lessons for learning a specific song and developing musical skills. Assessing this lesson plan according to <a href="http://www.luthersem.edu/mhess/VellaCE.pdf">Jane Vella's 12 Principles of Learning</a>, we see that not all of the 12 principles are included. The principles that are met are as follows:<br><br>Needs Assessment - The lesson plan calls on the music leader to assess the current level of skill of each child, both for the specific piece of music being prepared for performance and for their musical skills overall.<br><br>Sequence and Reinforcement - This lesson plan is taken from the "middle" of a sequence of lessons intended to teach musical skills and to prepare a specific piece of music for performance.<br><br>Immediacy - The general musical skills taught in this lesson plan are applied immediately to developing greate facility with the specific piece of music being rehearsed.<br><br>Teamwork - While not explicitly stated in the lesson plan, the nature of handbells is such that each musician plays specific notes; teamwork is necessary to perform the piece correctly.<br><br>Engagement - This lesson plan presents a "learning by doing" activity, as the children learn by playing the handbells.<br><br>Accountability - both the music leader and the children are accountable for the outcome of the lesson, as the ultimate objective is a performance of the specific piece.
