As educators, we are only as effective as what we know. If we have no working knowledge of what students studied in previous years, how can we build on their learning? If we have no insight into the curriculum in later grades, how can we prepare learners for future classes?
A curious observation is the uniform way that committees review curriculum for each field of study. Too often, authorities have a knee-jerk impulse to declare that 'all curriculum areas will be the same.' In fact, real and significant differences exist between fields of study.
