While my teachers were mostly delightful older women, school focused in large part on worksheets and not a lot of hands on involvement. Today's teachers, especially those who have graduated in the past ten years, tend to provide much more project-based and hands on learning. There tends to be more choice, too, for students so they feel more involved in their education.
I also feel, despite what some people think about teachers being lazy, it's much more difficult to be a "lazy" teacher now than it was in the past (though I only consider one of the teachers I had in school to be a lazy teacher). In the age of testing, teachers are held more accountable than ever before, and so now they have to work harder than ever before to provide a quality, well-rounded education for students.
