I'm one of those people that believe we need to rebuild the entire system from the ground up..knowing full well that it won't happen..but that it should.
I retired in July of 2016 after 36 years of teaching. Nineteen years of teaching social studies (mostly history, geography, and government) at the HS level, one year as a volunteer at an alternative HS and working at a non-profit called OperationFreshStart, and the final 16 years teaching GED social studies, Civics, and ESL at a medium security prison in Wisconsin. I also was an instructor in the US Army Reserves for 10 years (field medic, and NBC Defense). I also have 5 grown children, 3 of whom are involved in education (preschool, special education, and university).
I think our educational system has failed us, not for a lack of effort. I was a part of it and saw and participated in the effort, I put in the time, spent money (mine and the districts) to do my best, but I think I could have been twice the teacher I was and still failed. Look at what we've elected...not just president, what we've filled the chambers of Congress with..and our State Legislatures and governors offices. People send money to "televangelists" and other hucksters. Reality TV rules the airwaves and talk radio substitutes for civil thought and discussion. Millions text and tweet but can't write a decent paragraph. We tolerate urban blight and ugliness along our highways, while museums and performing art centers are on economic life support.
Schools teach us to read but not what is worth reading, and I'm afraid we also develop the ability to think without learning what is worthy of contemplation. We have the power of speech but fail to use it wisely or effectively. We have eyes to see, but fail to appreciate what we see. Isn't this what a decent education should lead to? We aren't very wise consumers, nor very literate, or well informed about history, the workings of government, or science.
Shouldn't our educational system be turning out young people who are enlightened, creative, thoughtful, skilled, talented, life-long learners? I'm sure our schools do now...that scattering of young adults that either "got it", or were just born with the right genes...but I think the schools could be designed to turn the 10% into 99%.
First I'd scrap the grade levels. You start school not when a law says you start, but when biology says you're ready. You also move from one level to another when you have shown mastery or competence of a skill, knowledge of information. As you master the skills, achieve the competence, you move on to the more difficult, more complex..not before. It doesn't matter that you're older, it only matters that you understand and are capable. If you can't do it then the system finds a way for you to do it. If it is important enough to be taught it is important enough to be mastered..it is not good enough that you "tried hard". I was constantly passed on to the next higher grade even though I failed math in 7th and 8th grades..I still can't do the times table and never understood Algebra even though I took it for 2 years..I was passed on the second year, as the teacher said.."as a gift". Don't include it in the curriculum if it isn't important enough to learn.
Don't separate the subjects. Is history separate from geography? No. How about science and math? Poetry and science..and literature and history, music and math..and science and art and history and geography and psychology and... Knowledge and thought are not compartmentalized in your brain, they spill over into each other. They should be taught that way.
The school should blend with the community. The students should share what they learn with the people of the community. Put on plays, give talks, interview people, gather and share knowledge. There should be contests between schools...academic, knowledge-based, creative, skills..things that are useful. These could replace the sports...and if you think that too outrageous..intramural sports can be included in the curriculum, outdoor activities, camping, geology, wildlife ecology, etc.
Like I mentioned in an above post...get rid of the textbooks. If ever there was a device designed to kill a student's interest in a subject, the text book is it. With the access to information that technology gives us today why stay stuck to those dead weights.
Blur the line between the community and the school. I think it is important to have trained, licensed teachers, but why not take more advantage of the local talent? Bring in the banker and the president of the credit union, the business owners, doctors, pharmacists, DNR specialists, government officials, farmers, local artisans, writers, and others...not just to "talk to the class" but to teach classes, be part of the curriculum. Students could shadow them for credit, they could team with them for community service credit. Community members should teach classes "after hours" for extra credit that adults could also take.
A lot of changes would have to take place..in the training of teachers, the buildings, the role parents and non-parents play...but if we want our schools to help solve our growing list of problems changes need to be made. Some already are being made...I fear most "reforms" though are only cosmetic, or band aides.
