The first wave of educational reforms in Macau took place in late 80s and early 90s. In 1991, the first Education Law was approved in Legislative Council. It signified a path leading to more “disciplined” education system. It was then by legislative means through standardization, regulations, implementation of the universal free education, establishment of the “public school net”, construction of a “localized” curriculum framework, and the definition of various kinds of teacher education enabled the government to participate in overall educational matters. Among all, curriculum development is a significant component in the arena of educational reform. The localized curriculum was first implementation in 1995 in all government schools with Chinese as a medium of instruction, and was not compulsory in private schools. Macau is now starting a second wave of educational reform, with special attention to the re-construction of the present curriculum. Thus, it is the objective of this study to examine and disclose the discourses and practices of the curriculum development in the territory in order to re-vision the future development. The time travelling tunnel gives two scientists the ability to travel in time and space in the television series in the UK in 1960’s. In this paper, ‘excursion into the time tunnel’ is used metaphorically, to describe the research process for it is to be adventure and an exploration. Furthermore, the metaphor ‘time tunnel’ also bridges the present to the past and the future. This is how the author attempts to reveal the story of discourses and practices of the curriculum development in Macau through the ‘time tunnel’ interweaving with the past, the present and the future. This study stems from a particular stance of educational policy analysis. The study is informed by aspects of critical and post-structuralist perspective, with particular reference to Michel Foucault. In this paper, official document, namely Gazette (known as Boletin Oficial in Portuguese) is the focal point of interest.
