Early exposure to quality musical activities benefits children’s holistic development and learning. It is, therefore, crucial to ensure kindergarten teachers can provide such activities for children. In Hong Kong, the Education Bureau (EDB) designed the Kindergarten Education Curriculum Guide (Curriculum Development Council, 2017). While music is included as a subdomain in the official curriculum, with specific learning objectives and expectations for children, there is a dearth of research on the musical activity types kindergarten teachers conduct in practice. Similarly, no research has been conducted to explore the perspectives of local kindergarten stakeholders (e.g., quality assessors) on quality music education. Investigating these topics is vital to guide subsequent professional development (PD) efforts in kindergartens.This dissertation portfolio draws on Campbell and Scott-Kassner (2019)’s theoretical framework of quality music education in early childhood. The overall objective was to explore the provision and types of musical activities in Hong Kong kindergartens and stakeholders’ perspectives on quality musical practices. This dissertation comprises three empirical studies. Study 1 was a large-scale survey study with kindergarten teachers (n = 1,019), investigating the provision of musical activities in kindergartens and the potential differences in musical activities among teachers with different teaching experience. Descriptive, non-parametric, and parametric statistical analyses were performed. Study 2 was a content analysis exploring the types of musical activities mentioned in 164 Quality Review (QR) reports published by the EDB. Data was analyzed using descriptive statistical analyses, word frequency, and co-occurrence analyses. Study 3 was a content analysis of 323 QR reports, exploring the positive and negative feedback and recommendations for improvement regarding music pedagogical practices mentioned by quality assessors in the reports. Data was
