For many people, a high standard for student learning is desirable. This
is what underlies current standard-based science education reforms
around the world. As someone who was born and brought up in a
less-privileged home and educated in a resource-limited school
environment in a developing country, I always had to study hard to meet
various standards from elementary to high school to univ- sity. My first
book in English published over 10 years ago (Liu, X. [1996].
Mathematics and Science Curriculum Change in the People's Republic of
China. Lewiston, NY: The Edwin Mellen Press) provided me an opportunity
to examine standards (i. e., Chinese national science teaching syllabi)
from a historical and political point of view. I argued that standards
are developed for particular poli- cal agendas in order to maintain the
privileged position of certain groups (i. e., urban residents) in a
society at expenses of others (i. e., rural residents). Thus, underneath
standards is systematic discrimination and injustice. Since then, I have
had opportunities to study the issue of standards in much more breadth
and depth. This book, Linking Competence to Opportunities to Learn:
Models of Competence and data mining, provides me an opportunity to
examine standards from a different perspective: opportunity to learn.
