I don't know if it's a coincidence, or if there are other forces at play. But today, during class, I noticed that all of my 11th-graders are solving all kinds of log and exponential equations fluidly without accepting any help from me. They were even completely comfortable finding inverse equations given a function like f(x) = a*b^(cx - d) all by themselves.
Amazeballs. This is the first time that I think my students as a whole really understand logs!
I still believe that the credit goes to this. Sometimes, it just pays to slooow theeem dooowwwn.
