The calling for transforming textbook development into evidence-based field have been concerned,while the path of how to develop evidence-based textbook still remains.This study aimed to retrospect the process of NCM textbook development in primary grades from an evidence-based perspective.Participatory Action Research and Triangulation was employed to explore how does NCM get to evidence-based textbook development.Qualitative research methodology of the semi-structure interview,focus group interviews,and verbal protocol analysis have been applied to collect data.The result indicated that the chain of evidence in developing NCM textbook includes preliminary practical investigation,fundamental research,systematic revision,learning and teaching trail,review and revision,typography and submission for validation.Furthermore,there are two key features should be mentioned,including forming a complete chain of evidence from fragmented to systematic;Situation+question string establishes the textbook style,and achieving learning-centeredness with the Five Unifications.It manifests how does NCM carry out evidence-based textbook development.
