Neither here nor there...but.....my father was a high school math teacher\dept head for 35 years. Every August he would meet with his counterpart at the state university to verify what his seniors needed to know as freshman. He would then call for the grades then end of the freshman first semester.
The results: The average freshman calculus and finite math student GPA for the last 10 years before he passed away: 2.67 The average GPA for his students: 3.81
I could tell you stories about my dad and other teachers for days and days. I'm sure there are some of you out there who can do the same. Right or wrong, agree with their methods or disagree, no one ever became a teacher for the money. If you are unsure of why they are teaching something in a particular way, ask, I'll bet you will get an answer that just might surprise you.....like having the basic understanding and usage of a Ti-85\6\9\91 to better prep them for freshman math. Yeh, they will show you in college if they have to....unless you test out of freshman math....then you are sunk...anyway.....I probably shouldn't have even responded to this thread....but that was my .02
