The Hidden Power of Learning Objectives

No matter what standards you use, there is a constant in every lesson: the learning objective. Objectives are the basis of what you hope to accomplish in any given lesson. A more powerful term, Student Learning Objectives (SLOs), are a specific learning goal coupled with a specific way to measure where students are in meeting that goal. SLOs can be large and meaty goals that teachers aim to meet over the course of a year of instruction, but mini-SLOs can happen each and every day in class.
