Worldwide, the interest of policy-makers in participating in studies from the International Association for the Evaluation of Educational Achievement (IEA), such as Trends in International Mathematics and Science Study (TIMSS) has been growing rapidly over the past two decades. These studies offer the opportunity to relate the teaching and…

Studies like the Third International Mathematics and Science Study (TIMSS) have compared the performance of U.S. middle grade students (i.e., eighth graders) to those in other countries. In relation to middle grade schools, 20 countries outperformed the United States in mathematics and nine countries scored above the U.S. in science. The intent of…

The 2007 Trends in International Mathematics and Science Study (TIMSS) is the fourth administration since 1995 of this international comparison. Developed and implemented at the international level by the International Association for the Evaluation of Educational Achievement (IEA)--an international organization of national research institutions…

On March 13, 2008, the National Mathematics Advisory Panel submitted its Final Report to the President of the United States and the Secretary of Education, and it was officially released to the public on that date, as well. The Panel agrees that the delivery system in mathematics education--the system that translates mathematical knowledge into…

This paper draws on a large Australian commissioned research study that mapped classroom pedagogies called "productive pedagogies". The model of pedagogies derived from an admixture of theory and empirical observations and worked together what Fraser (1997) calls a politics of redistribution and a politics of recognition in its desire to…
