I think generally tutorial is a broader term than you're refering to. I've never really thought about it, but the first "php tutorials" and "javascript tutorials" I ever looked at were tutorials, so were the instructor-led practical machine learning classes at university. Wikipedia says "A tutorial can be taken in many forms, ranging from a set of instructions to complete a task to an interactive problem solving session (usually in academia)." - which seems to encompass everything from online tutorial explanations, to online video courses, to academia itself. That matches my experience with tutorials anyway.
