Assessment: Learning communities can use it to engineer a bridge connecting teaching and learning

摘要

There is today a bewildering range of coherent approaches to school improvement, almost all of which can be shown to have a significant effect on student achievement. The question is: Which investments provide the best value for the money? It is becoming clearer that the teacher is the most important influence on student achievement (Rivkin, Hanushek, & Kain, 2005). Students who get the best teachers learn at twice the rate of students taught by average teachers (Hanushek, 2004). We can get a greater improvement in teacher quality, at a lower cost, by investing in teacher learning.
