The project aims at promoting the concept of Positive Psychology in 10 secondary schools. Through the introduction of 'Playback Theatre' (一人一故事劇場) and engagement of the participated students (senior forms) in small group training and drama performance, their positive thinking and emotions can be enhanced. Teachers and school social workers will also be trained to help in the Playback Theatre activities for creating a more accepting environment to facilitate students' positive growth and well-being. Development of a teaching kit incorporating the theory of Positive Psychology and Play Theatre, application skills and teaching plans of the training workshops will be the tangible deliverable.
