And I guess that making a certification easier to pass devalue a certification to some extent - I was reading the other day how some employers looked at certification with disdain since they had hired some certified and found that they didn't know as much as they had expected.
This book is writen by an author that was involved in the actual Sun exam. Therefore, it is logical to expect that you'll be told what you'll get on the exam
Nearly everyone that get her/his hands to this book gets certified with fantastic score(Yeah, what's up with that? It's kinda strange..)
This book will create a warm, fuzzy efect on you after you read it-probably cause of the jokes and characters. You will be convinced that you actually learned something.
a firm, nice overview of the technology
but won't know how to apply it
If 1,2,3,4 are TRUE, than it is likely that HFSJ can degrade the value of the Sun's SCWCD certificate
you do not address the "expectations" that the the "Head First" phenomenon is creating, i.e. that everything should be this "easy".
As you have accurately pointed out, creating easy and interesting material is more time consuming and not always appropriate in a technical field that is evolving very quickly - in fact sometimes you have to be grateful that there is any documentation at all - which most likely had to be created in the most expedient fashion possible.
While the "Head First" approach is beneficial from the learning perspective, it also seems to have created a significant group of people that will not venture into any new territory that hasn't been already explored by "Head First".
I'm sorry but as a professional in this field you have to be able to read and extract the facts from dry and convoluted specifications, white papers, articles - most of which are produced under extreme time pressure.
Ultimately the only documents that you have any control over are you own
You should note that I approve the HF-theory about efficient learning. But, I think that that's the reader job--to know to 'put himself in efficient mode'. He should know best from his experience. Why don't you just publish a book, let's say, 'Head First Thinking' , and describe how you should learn. Then, make a recomendation to that book from your HF-series. Then I can use your HF-series without the things I find a bit irritating. This seems pretty OO to me, opposed to 'repeating the code' in every HF-book. BTW, I know that's impossible for many reasons.
