The best system I've seen is used by the U.S. Army Ordnance Center and School. You start with Basic knowledge and skills, (This is a hammer, this is a screwdriver, etc.) Students are taught how to use and care for tools. Next comes classroom presentations about the operation of a simple engine (explain combustion process, cycles, etc.) Then each student gets a B&S 5hp engine to completely disassemble, inspect, and re-assemble. The engine must run properly before moving to the next step. Next we each received a GM 6.2L diesel HMMWV engine and repeated the process. Electrical components are also worked into the schedule as needed (alternators, starters, etc.)with the appropriate information about theory of operation. At the end of the program, a vehicle is rigged by the instructors to simulate problems that require troubleshooting. Think clear lacquer on a set of points, kinked fuel lines hidden from view, etc. You will have much better results when the student has a good knowledge of what is supposed to happen in an engine, transmission, or electrical system before they touch it. If you show someone how to perform a tune-up without an understanding of what each component is supposed to do you have only shown them how to be a parts changer. Suggested reading- Army TM 9-243 "Use and Care of Hand Tools and Measuring Tools" and TM 9-8000 "Principles of Automotive Vehicles" Both publications are readily available in the public domain- they are not copyrighted. Just my two cent's worth, hope it's helpful. Gary- US Army MOS 63G, USAOC&S honor grad-1987.

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
