Federal policy under No Child Left Behind (NCLB) and the Department of Education’s ‘flexibility’ waivers has sought to address [the problem of international competitiveness] by beefing up testing policies — requiring more tests and upping the consequences for poor results: including denying diplomas to students, firing teachers, and closing schools. Unfortunately, this strategy hasn’t worked. In fact, U.S. performance on the Program for International Student Assessment (PISA) declined in every subject area between 2000 and 2012 — the years in which these policies have been in effect.

Now we have international evidence about something that has a greater effect on learning than testing: Teaching. The results of the Teaching and Learning International Survey (TALIS), released last week by the Organization for Economic Cooperation and Development (OECD), offer a stunning picture of the challenges experienced by American teachers, while providing provocative insights into what we might do to foster better teaching — and learning — in the United States.

In short, the survey shows that American teachers today work harder under much more challenging conditions than teachers elsewhere in the industrialized world. They also receive less useful feedback, less helpful professional development, and have less time to collaborate to improve their work. Not surprisingly, two-thirds feel their profession is not valued by society — an indicator that OECD finds is ultimately related to student achievement.

…

Nearly two-thirds of U.S. middle-school teachers work in schools where more than 30 percent of students are economically disadvantaged. This is by far the highest rate in the world, and more than triple the average TALIS rate. The next countries in line after the United States are Malaysia and Chile.

…

Along with these challenges, U.S. teachers must cope with larger class sizes (27 versus the TALIS average of 24). They also spend many more hours than teachers in any other country directly instructing children each week (27 versus the TALIS average of 19). And they work more hours in total each week than their global counterparts (45 versus the TALIS average of 38), with much less time in their schedules for planning, collaboration, and professional development.
