Hi David: Good example and analogy. Senses contribute to learning. Whenever more senses are involved, it stimulates different parts of thye brain, and contributes to better information retention. Of course, we are seeking long term memory. The best way for this is review - during the presentation, immediately after (as homework or review at home after class), review early the next day, then again in class. That doesn't mean we can't quiz daily, but practice and review is very important towards long term memory retention. And students can use their senses in their study and practice as well - not limited to the classroom. Regards, Barry
