Last semester, Tomarken also faced another problem – the lack of a good textbook for teaching structural equation modeling to social science students – that he solved using technology. “There is no book that is perfect, that really is appropriate, for this class. There are either books that tend to be too easy or too hard or just not broad enough in scope.” Tomarken solved this problem using the Prometheus system, by placing his lecture notes on the web. This not only replaced the textbook, it allowed students to spend more time focused on the lecture and less time copying formulas from the board. “I told them, you don’t have to write anything, it’s all on the web, just listen.”
This song will help students memorize the quadratic formula to better understand how it is used.
