I believe the best teachers use multiple methods of teaching, and adapt those to the individual classes they teach. Not all students will respond in the same way to different forms of teaching, however, I feel that the best approach is to try to be as varied as possible from the beginning, to keep students engaged.
When I was in college for my undergraduate degree, I had to take a few World/American history courses (not Art History, those came later), and in high school and my first history classes in college, it was my least favorite subject. Most of the classes were focused on the politics of the time, or general dates and facts of the people at the time, and all of them "taught from the book." We had to read about these times in our text books, which were almost exactly what was reiterated to us in the lectures. We listened, gathered the facts and then regurgitated them back to our teachers and professors by way of tests. I was looking forward to the day I no longer had to take history classes. That is until I took a history course with a female professor (her name unfortunately escapes me at the moment), who taught the class in a completely different way. The course was on American history from around the 1500's until early 20th century. We did have a book, but instead of having us read and then listen to a lecture practically verbatim, the professor would come in and just talk off the top of her head, and tell stories about the historic times we were learning. She would interject with personal anecdotes, and I would sit and listen fascinated by her story telling abilities. Instead of asking us to read and memorize a list of dates and facts, she had us watch movies about the topics we were learning about (the Salem Witch trials, or slavery, for example), which reinforced visually what we were learning. She also had us take the topics we were most interested in, do research outside of our text books by reading interesting historical books that were written about the topics, and write papers that included not just regurgitated facts, but also our own opinions and thoughts about the way things were. She employed a multimodal way of teaching that completely changed my view on history. History became one of my favorite topics and still is to this day. Although I went on after that class to take art history classes that were similar to the ones I had taken before, I was able to start to think more critically of what I learned, and was more interested in doing further research beyond just memorizing dates and names. Not only did my professor teach in a way that made me excited to learn, about a topic I had previously had NO interest in, she actually taught me ways to be a better teacher overall, long before I even thought about teaching. She taught me about being a connoisseur of a topic, taking all of the elements of something and knowing them fully, so that you can combine the aspects to create a dynamic and unforgettable curriculum.
As I am learning to be an art educator, I find myself remembering my own learning experiences and trying to teach in a way that is both engaging, memorable and will connect to the students who are not just interested in making art, but also those who think that art is a waste of time. My undergraduate professor did that for me, with history, and even though I don't consider history a large part of my career, it is something that continues to fascinate me and interest me and informs what I do as an artist and in my life in general. If I can get students to feel that way about art, for those making it a career and those who are not, I truly feel that future generations will be living happier, more fulfilled and well rounded lives.
