The New Senior Secondary (NSS) curriculum was launched among Hong Kong schools in 2009-10 school year. Under the NSS Curriculum framework, Other Learning Experiences (OLE), which requires students to participate in five areas of OLE, namely Moral and Civic Education, Community Service, Career-related Experiences, Aesthetic Development and Physical Development, is one of the three major components that complement the study of the four core subjects and 2-3 elective subjects for the whole person development of students. The study, mainly employing surveys together with mixed methods, aims to explore the impact of OLE, as a key curriculum component in the NSS curriculum, on students' approaches to learning. In 2010-11, two case study schools, with different features of OLE and with differing background characteristics were selected for a survey on students' approaches to learning over two school years. The survey, namely ‘Studying at School Inventory' (SASI) of 352 S4 students provides evidence of the impact of OLE with regard to learning approaches such as enhancing deep learning and effort. Although the results could not of themselves provide a warrant for a generalizable positive impact of OLE on students' approaches to learning and learning habits, it is reasonable to conclude that OLE has had a positive influence as indicated in policy documents, at the two case schools and in certain school contexts (e.g. year group, school culture, OLE leadership) and with regard to specific OLE component contexts (e.g. activity type, student motivation, pedagogy). The study illuminates the further study of OLE.
