Previously, in 2012, the center welcomed Mrs. Bethsmat, the expert of therapy activities from United Kingdom in 2014 working as a volunteer for one year and Mrs. Madeline Entwistle, the expert of therapy activities from Australia working as a volunteer for 10 months. The two therapists trained the staffs about the therapy activities and relating games so that the teacher could combine the activities of learning with playing, giving children many opportunities to discover the surrounding world and reduce their distraction.
