I’ve done this in the past with that age group this is how i attack it.
Firstly give explanation of IDT most wont know what it is. Then i show them daniel simon, carl liu, scott robertsons stuff and explain this is a sketching at its best, then show them my work and explain the lessons taught will give you great foundations to become like or better than the three super stars. As i said most will not know about IDT let alone what IDT sketching is so explain how it takes years of practice and dedication to get to the top level so they are not put off because they can’t do it instantly. I would add it is extremely important not to pull the wool over their eyes, be honest, if your sketch levels are average dont pretend your the next syd mead, explain you are teaching them theory and your still practicing yourself, if your the next carl liu great!
Explain the different types of sketch and how they are used and the sole purpose is communication not a work of art.
Ban rules and erasers. Dish out aload of bic biros and OHP fine point pens and make sure they draw big.
It will be highly dependent on their existing skill levels, suss out the class. Remember at this age they won’t all be budding IDer’s some just won’t get it, when I first did I struggled a bit trying to explain to some of the students who just couldn’t imagine a shape in 3D (to solve this I used 3D foam core models). Also some really wont care as amazing as it sounds. In which case do not get frustrated remain cool.
It is always best to work to a goal, by the end of the two weeks we will have drawn car\hovercraft\drill in different views with maybe some explanation drawings.
Remeber your doing this as well you have to keep the enthusiasm up for it to.
Drawing straight vertical lines across the page. Explain you use the arm to draw and not the wrist .
Do a quick explanation of 1, 2, 3 point perspective, the class will let you know if they have done it before or if their bored. Break out the cubes, rectangles focusing on proportions and perspectice views, what are they trying to communicate stuff on the top side etc… ensure their not doing the classic vertical line in the middle and hugeley extreme pespective square that seems to be in all the 2point perspective books.
Elipses, Explain the theory minor and major axis. Key is to get their eyes to see when an elipse is wrong do the whole page of elipses breaking down where the minor and major is, slap on some perspective guidlies fill them with elipses , do some boxes slap on some elipses. (Re visit elipses every session)
Drawing through an object, get the students drawing through any shape, projecting lines Depending on how quickly they pick it up end the session with a 1 point perspective cool looking hover craft there easy enough to do it will keep their enthusiasm till the end.
------------ End session
I would build up their skills week 1, then end of week 2 get them doing their OWN stuff allow them to experiment.
Im pretty much just regurgitating Scott Robertson’s DVD’s. How did you learn you must of learn’t somehow. Also lastly do it with them! Hook up a camera and projector and let them watch you yeah nothing more exhilrating.
