If you find a curriculum is confusing then more than likely the author has an ideological basis for making it confusing.
Sure. American history books, for example, are created with the ideological bias that the US Government is an entity that should exist--an assumption that is rarely questioned. This bias tends to make them simple to understand, yet deadly boring.
I don't teach American history, I teach world history. Yet, the other teachers who teach the same subject with the same content standards in my school (two of whom are Native Hawaiian, one of whom teaches in a Hawaiian Language Immersion Program), tend to do different activities based on their own strengths in teaching. Few public school teachers are comfortable with talking about religion as much as I do, for instance.
I do not believe that the fact that we are all taking different approaches means that some or all of us are doing it wrong. In fact, I rather think we might lose more than we gain by standardization.
