I've got a lesson on Wednesday where the class (yr7) are using their voices to produce a piece of music based on the elements of music. I'm starting the lesson with singing, before they are using symbols to put sounds to. My worry is low confidence pupils - how can I encourage those who are reluctant to take part?Whenever I do singing, I make sure I sing with confidence and conviction and always point out that my singing on my own is far scarier that what I'm asking them to do, which is sing as part of a class/group. Are there any other tactics I can use in the lesson to encourage pupils further? Especially those that are point blank refusing to get involved because of confidence issues.
