Kinetic Chain Assessment and Learning Computerized System for Cantonese opera: The development, validation and application

This study aims to promote the assessment of, for, and as learning of Cantonese opera with the development of the Computerized Kinetic Chain Assessment and Learning System (CKCALS). The CKCALS captures and calibrates the coordinates and angles of the skeletal joints during learners' movements, compares them with the standard set by the experts, and provides instant feedback for learner's subsequent learning. Fifty-nine persons were recruited for system validation, which was followed by system refinement and application for an intervention. Investigations are planned for changes to students' performance and their motivation and self-efficacy with regard to learning Cantonese opera.
