I taught college automotive courses for 5 years after I retired (aged out) of my "real" job, it was the most frustrating yet fun job I've had. I loved interacting with my students, even tho only about 1/3 of my class was there to actually learn. I had a great department chair who really handled the political crap well and kept almost all of it off my plate while still teaching at least 2 classes a semester and in summer too. One of the major discussions we had every semester was am I teaching to teach or teaching to pass the tests? Because getting a significant percentage of students to pass the course was a requirement - whether they learned anything or not. The first day of class I gave the final exam - it didn't count of course but was used to gauge progress by comparing the scores for the same test at the end of the semester. Every year I was appalled at the low scores, both the first and last time around on the test!
I retired at 5 years because the incoming president changed the educational requirements for the teachers and while I could have taken courses to meet those requirements and kept teaching (the school would have paid for the classes too) I felt there was a real disconnect between me and the students I was trying to teach - I blame me as much as the kids - but we really couldn't "relate".
Of course, 1/3 of my class were kids who were told by their mom either get out of the basement and go to school or get a job and move out, another 1/3 were actually on "work release" and were taken back to jail after class and the final 1/3 were actually there to learn. That may sound harsh, but it was fairly accurate......I think the same holds true for elementary and high school students as well (maybe not the jail part) in that it's up to the teacher to not only educate but entertain and enlighten, get the kids to want to learn. I didn't have it in me - I thought they should want to learn - after all, they were paying for the classes - and because I had all the answers that they would at least ask questions. It was like trying to talk to a group of rocks at times......
We did active shooter training every semester, along with racial and gender sensitivity training, IT safety training and on and on.....it felt like I spent as much time at school training for training as I did teaching!
The pay was meh, no bennies since I was an adjunct and not full time, the only real bennie was access to the shop when there were no classes scheduled there. I miss that! We had a great facility, with all the auto equipment (including alignment machines that used frickin lasers!) you could even need or want, and access to fully stocked machine and welding shops as well.
When I left in my department there was one full time teacher, the department chair and about 10 adjuncts as that's all they would pay for......
I know this is a long read, but one of the things that caused issues for me as a teacher was the absolute lack of basic education in my students - an example: I was teaching how a thermostat worked, so I asked the class what temperature water boiled at - crickets! Another time I was trying to teach induction so I started with magnets - no one knew that magnets had 2 poles, or anything about magnetic attraction, repulsion or lines of force. That was stuff I leaned by 2nd grade! It was woeful......no one could write a complete sentence let alone a paper discussing even a subject they were familiar with like their favorite car.
I was happy to leave the self imposed stress, but felt a complete failure at the job, even tho my chair and a few other teachers thought I did a good job.
