I am an elementary reading specialist with a kindergartner and a 2nd grader. As a teacher and a parent, I like the CC. As a teacher, I am more sure of what I am teaching. Instead of a teacher edition that says to teach compare and contrast, I have standards that give me more specifics that I know are going to build on what the previous grade did and prepare them for what the next grade will expect. I have never taught a reading curriculum that has done that before. I also really like how the CC teaches kids to use higher level thinking. It teaches more analysis and expects kids to find evidence that supports their response.
As a parent I like that I can see exactly what skills my kids are learning and how those skills are going to progress throughout their entire K-12 education. That has never been possible for me to see before. The standards are exactly the same for K-12. What changes is the complexity and rigor of the standard.
For example, this is a standard for my kindergartener: Identify characters, settings, and major events in a story.
This is the same standard for my 2nd grader: Describe how characters in a story respond to major events and challenges.
This is the same standard for a 12th grader: Analyze the impact of the author’s choices regarding how to develop and relate elements of a story or drama (e.g., where a story is set, how the action is ordered, how the characters are introduced and developed).
The majority of the complaints I see about the reading standards have to do with the texts that kids are expected to read. If you look at the CC as they were written (www.commonstandards.org), there are no mandatory texts to read. A standard M. suggest a text, but it is only a suggestion. For example, this is a 3rd grade standard copied directly from our CC: "Compare and contrast two or more versions of the same story (e.g., Cinderella stories) by different authors or from different cultures." If students are being expected to read certain texts, that is a district or state implementation. The mom who said her 10th grader's English focus this year was on women in society, that must be a district decision. I just looked at the 10th grade English/Language Arts standards and there is nothing about women in society. (Our system hasn't adopted the social studies standards. Maybe it is a SS standard, but it isn't an English standard.) Our district has basically told us that we can use whatever text we want to use to teach the standards. At least at the elementary level, we don't have a single required text that the district or state requires us to use.
One of the things that really gets me the most is the complaints I see about math. I have seen several examples of supposed CC math problems going around the internet. The poster usually says something along the lines that they are a CPA or majored in math and they can't understand their 2nd grade student's math homework. I look at those problems and I think that is how I taught my 3rd grade students 20 years ago!! One of the examples I've seen is almost identical to an assessment question that my 3rd grade students had to answer 5 years ago. And yes, I expected them to write an explanation of how they solved the problem. That was at least two years before the CC was made public. It had nothing to do with the CC. It had everything to do with the curriculum I was teaching. Everyday Math (a very common math curriculum) has expected kids to explain their answers forever! The Everyday Math curriculum teaches a lot of mental math and teaches the process and not just the memorization of facts. Again, it is the teaching of higher level thinking. Several people commented on how confusing it was to have all the drawing of blocks, dots, and circles. That is how I was taught to do math in the 1970s and how I taught math to my students in the '90s and '00s. It isn't new.
As far as testing...you can thank the federal government for that going back to when Bush put the No Child Left Behind laws into place. Again, the testing has nothing to do with CC. States have designed tests based on the CC, but they would still have to give the tests even if they weren't adopting the CC. Trust me, teachers hate it probably even more than parents do. But, our hands are tied. More and more districts are using computers for testing. Doing the tests on the computer gives instantaneous results. We no longer have to wait 6 weeks or more to get back results. Our kindergarteners take their first computer assessment in January. They take it again in M.. 1st-5th grade take the assessment in September with the option to give it again in January. I think giving the test in M. is also optional. Those are standardized tests that are given to meet federal and state requirements. We also use that data for determining students who need extra help in math and reading. Every student takes regular tests in every subject. Sometimes on a weekly basis. Those tests are used to monitor progress.
I strongly encourage you to read the CC standards in their purest form, as they are originally written. They aren't as bad as the opponents seem to think. More than likely, it is what the state or district has done to make the standards their own.
