@Dutchess_III No group of any aged people all like the same things. But just like it is now, you can teach to all the kids with a variety of examples. The key is that there are ways to teach to kids that don’t make it drudge and that can get kids engaged and understanding there are reasons for what they are learning.
On a slightly tangential view, you can also change the format of the class. When my kids were in school, I was a very involved parent. When my daughter was in 5th grade she had a history teacher that was absolutely killing the kids. They were having to write a report every night with a big report assigned on Monday that was due on Friday. That was a whole lot of homework in history on top of all the other classes. I finally went in and talked to the teacher. She was an older teacher that had been teaching for many years. I asked her why she was assigning all the reports as homework. She said it was history and that is boring for many kids. She didn’t know of any other way to get the kids to learn the material. I asked her if it was helping. She said it wasn’t. I told her of a French class I had in 8th grade where the teacher set up her class as a game room. Desks were arranged in an arc pattern. One desk was seat 1, the next 2 and so on. During the class she would ask the first seat a question. If the student answered correctly the next question went to seat 2. If the question was not answered correctly the same question went on down the line, seat by seat, until it was answered correctly. The child that answered correctly would then move to the seat that started the question and everyone else that answered incorrectly would move down one seat.
As I was explaining this, I could see the teacher getting very interested and excited. She said she thought she could do something like that. The massive report homework stopped. I checked back in with the teacher a week or two later and asked her how it was going. She was all smiles. She told me that even kids that were failing her class were telling her they were going to study so they could “win” the class. Test scores went up and interest in the subject went up.
There are many ways to change how we typically teach to get better results.
As for teaching to my niece’s class, that is moot at this point. She’s mid-30’s…no class to teach. However when I was working at the nuclear power plant, one of my friends was the AP chemistry teacher at the high school. I was a supervisor in the chemistry/environmental section at the plant. He asked me to come in and spend a day talking to his classes. The kids were very interested and I challenged them on their thinking. I even brought in some real life chemistry issues we had seen, giving them the initial indications we had and asked them to think about what could have caused them. This turned into a yearly thing towards the end of the school year.
There was also a news story I saw once that talked about a guy who had formed up a company in western Pennsylvania. He saw the need for more interest in the sciences in the schools so he got a lot of high tech chemistry and physics type equipment. He then coordinated/contracted with several school districts. For a given fee he would take a piece of equipment to the school, set it up and show the teacher how to operate it. He would do the same with a different piece of equipment at the next school, a third to the next school, etc. After a week or two he would then go and swap out the equipment for something new, usually rotating from one school to the next. So the kids got to see the equipment they might not get to see until they got to college normally. They were excited and very interested. They noted that within just one year the grades were going up and the number of students going on to study in a scientific field in college went way up. Since so many school districts were involved, the cost of the program was split up to the point where none of them were struggling with the cost and they guy that founded the company was making good money. A win-win-win.
