Instruction is a one-way delivery (from teacher to student) of information about what to do in order to accomplish a task. Instruction is often textural, with some pictures (e.g. a textbook or user manual). Instruction is cheap, because you only have to write a book and provide a hard copy or a web site access. However, the Adult learner is easily bored, and even the youth learner now wants to "see it in action" (also, reading comprehension is a tricky thing).
Training is hands-on use of the tools and implementation of the technique, usually be teacher demonstration and student practice. Training is expensive, as it requires an instructor, (time) getting together (travel) with students in a workshop (rent).
Video Tutorials are a hybrid of these two techniques, building on the strengths of each and minimizing the weaknesses. to view
my Blender Tutorial collection, please visit my Vimeo site. Once recorded, a video tutorial can be delivered on demand. The student is spoken to one-on-one, and shown how to do something, step-by-step. Instead of not being embarrassed by asking stupid questions, or asking the instructor to repeat something, the student can simply replay the video. Coupled with a workbook, the student can practice, step-by-step, using their own work facilty (no travel or rent). Different language tracks can accompany the same video, enabling consistent training in different countries.
