Dr. Renyard, I teach an advanced performance engine building, tuning course. I would say that 95% of my students are hands on learners, like myself and have a hard time staying focused while reading or working on a computer. Group discussions turn into what we call in the racing industry as bench racing sessions. There are more untruths than facts. As an instructor it is my job to help separate fact from fiction. My students need a more structured environment. I have to be involved, which I am. Engine building is a science, and needs to be approached with logic. A slow logical approach is needed to be successful. Instant gratification just doesn’t happen. You wouldn’t want a medical doctor to learn surgery on a computer without going thru an internship. I am a mentor, a manager, a motivator and a monitor.
