Beaman and Wheldall also insisted on the fact that children receiving positive verbal feedback tended to be more on task and therefore less disruptive than children who received little. (2000)
There are plenty of ways to give positive feedback. Of course the verbal use of praise is one of the most common but your non-verbal intervention can also be very positive for the learning in your class. If you want to praise an achievement you may think about using expressions such as “Well done, you did the task really well!” “Excellent, you have settled down really quickly and you are ready to work with all your material.” “Good job, now you can work on the extension task” or simply clap your hands in an encouraging way.
Your comments also need to be genuine and specific.
Non-verbal praise can also be used as a complement to positive verbal feedback. Use body language as much as you can. You can clap your hands to gently applause for a group project for example, use “thumbs-up” to celebrate achievements, nod to approve students’ feedback. Don’t forget to use your face as a means to convey feelings. For instance you can smile to encourage continuation or frown to show that you are expecting more.
