Anyway, as an educator that has taught around the world I have a few short points to make.
1. The American education system ins't bad. In fact it is great.
2. It is incredibly diverse and no one can objectively say the entire 'system' is bad when there are in reality thousands of systems in existence(50 states, private schools, board schools, home schools, alternative, etc.)
3. American students are superior critical thinkers. I don't know if this is cultural or a function of the education system itself. However, American public school students reject authority and are willing to create their own answers and solve their own problems with the least amount of scaffolding. This is especially true when matched up against the Confucian based education systems in Asia. While my American students always had more difficulty memorizing facts, reading through large amounts of content or performing complex equations, they were generally much better at interpreting, analyzing, creating their own solutions and forming their own opinions. Again, I am not certain if this is a function of theory's like Bloom's Taxonomy having played such an important role in American education over the last few decades or if it is simply cultural.
4. Education problems in America are generally less a problem with the system itself than societal problems. IE: Fatherless homes, family's that don't place an importance on education, etc. Statistically America doesn't do as well because it attempts to educate, not only all of its students but a more diverse group of students. English language learners(ELLs) make up a large portion of the K-12 system and are held to the same standards that native speakers are held to. This population isn't stupid but it is obviously a great deal more difficult to learn content while also learning a new language and the catch up time is immense. Even students that speak the language will struggle to read and write(especially academically) for years. On top of this America includes the stats of everyone under the special educations umbrella. EDs, LDs, CDs, Autism Spectrum, the list goes on and on. When looking at stats one has to realize that America attempts to educate everyone which is noble but then it judges them based on them same standards, which is foolish. The stats will be forever weighted against them.
5. Teachers are more highly qualified than ever before. Have you ever tried to teach? The hoops a person has to jump through to teach in this country are incredible. The standards a teacher has to meet to be considered qualified are more stringent than any other country(even considering that these vary wildly state to state). This is more true in the last decade than in the past and yes, there are bad teachers who slip through the cracks or are simply broken by the system or their students, but the standard to get there is high. Bachelors, EDTPAs, Praxis exams every few years, certifications and cert renewals, keeping up with new content standards, new teaching initiatives and learning theories, the slightest of crimes guaranteeing the end of a career, constant evals and then your wage and 'performance levels' are published in the paper for the entire world to see. I can not think of another career field in America that requires as much from a person.
There is a lot I would like to do to change the education system in America. However, I do remain firm in my belief that, as a whole, it remains one of the world's greatest endeavors of all time.
