Here what is wrong if you want to do some thing. You start at step A go to step B then to step C. You see what A and B did to get to C. I like C Can't you just
give me
C that's all I need
That is exactly what is 'wrong' with most self-taught learners. If understanding of A and B are fundamental to C, then without learning A and B well, C is never really understood. If the learner skips over A and B ...
And that what's wrong. I like it when some one tell's me what I did wrong with A and B so that in the end I can get C all by myself.
That is a much better stance; and quite different from your first sentence! Other people may learn differently, too.
Now if A was, say for example, English, which is fundamental to communicating, I think many people gloss over learning A well, thus don't know the difference between no and know, for example.
It seems as though many of today's learners are just like your first sentence; they don't want to know, they just want the degree. I think industry supports this. Don't companies hire, then totally train the new hire to their own methods and ideologies?
No worries, though, as a paradigm shift has to happen; things are not working the way we are doing them... (economic crisis, indeed!)
I would hope any graduate would know about 555's, they are a very useful chip for all kinds of purposes, and often used in industry and domestic products. Perfectly reliable chip for a great many purposes.
I would also hope they knew all about them long before they got as far as Uni, what kind of Electronics student gets as far as Uni never having used (or heard of) a 555? (a completely useless one?).
I have to agree with this, and I think anyone who understands electronics should understand a 555, which is just a simple integrated circuit, made of a few transistors ... not too tough to do an analysis to understand how they work
And they do, still show up in many commercial designs...
