The education reform in Hong Kong advocated the Project Approach as an effective pedagogy to support childrens' learning through exploration and play. This paper outlines a case study of a Hong Kong kindergarten which implemented the project approach using a picture book and digital picture book as a stimulus to begin the project topic and develop the inquiry process. The qualitative data sources included analysis of documentation such as teacher lesson plans, teacher questionnaire on reflection, documentation of children's works and activity photos of the project. The findings revealed that picture book was a good stimulus to arouse children's interest. The children were observed to be highly engaged in the investigation and the benefits from the picture book in project were not limited to literacy learning but also integrated learnings such as in the domains of music and movement, drama, and science. Additionally, the project provided opportunities to use the 21st skills of collaborating, communicating, creativity and critical thinking. The case also acts as an example of implementing the project approach in a non-Western context and recommendations are made for Hong Kong early child educators who participate the education reform.
