Design And Validation Of Computer Protocols Review

Average Reviews:

(More customer reviews)You have probably read the text from the back cover of the book, which is cited above. Every word of it is true. This is an excellent book, even for (serious) beginners, but also for experts who need some advice on how to avoid bad designs.
All in all it is a joy to read this book as a thorough introduction to the subject. But I have to mention some criticism:
1. Holzmann did the research for the book in the late 1980s and the book was copyrighted in 1991. Therefore some parts look a bit dated now.
2. This is probably one of the best books on the design of network protocols. But who designs protocols ? Do you intend to specify a new protocol ? Probably not. For all those mere mortals who just want to have a quick look at the basics of network protocol, this book is probably too much material. And I am afraid, those few people who do indeed design protocols might take it as a weakness of the book that it does not focus on their favourite protocol family. Instead, Holzmann shows them how to design and verify (!) the correctness of completely new protocols.
3. Network protocols have a long history ! Still today we can learn from historical prototypes. Their basics can be traced back hundreds of years and it is a joy to see how Holzmann mentions them again and again even in the later (more formal) chapters.

This volume discusses the fundamental problems of designinglogically consistent methods of communication betweenmultiple computer processes. Standard protocol designproblems, such as error control and flow control, are coveredin detail, but also structured design methods and theconstruction of formal validation models. The book containscomplete listings and explanations of new protocolvalidation and design tool called SPIN. Author is in chargeof protocol design at Bell Labs. Professionals who boughtTanenbaum's COMPUTER NETWORKS, 2/E and Comer's TCP/IP willbuy this. This is the first book to cover automated protocoldesign and validation tools extensively.

Foundations and Best Practices in Early Childhood Education: History, Theories and Approaches to Learning (with MyEducationLab) (2nd Edition) Review

Average Reviews:

(More customer reviews)I think that Follari wrote this book with a particular course aim in mind, one focused ONLY on theory. It only covers historical figures, theory, curriculum basics, and some issues of early childhood education. It doesn't go into any dynamics of the classroom by comparing infants/toddlers to primary school children and kindergarteners. If this is all that you need, then you have it here. I, however, think more is needed to make the book worth the price.
It's divided into three parts: foundations, models, and a "practical" section (which she calls Beginning the Journey). Part 1 focuses on the basics (obviously) while Part Two outlines the curriculum models that early childhood professionals must know about today. Part 3 is one chapter, an amalgamation of all of the previous eleven chapters into some sensible professional framework. It makes for a very dense, kind of abstract manual on the whole.
Out of all of the three sections, Part 1 works the best namely because of how it briefly, informatively, but clearly outlines the historical figures and movements of early childhood education in Chapter Two. This segues perfectly into constructivism within Chapter Three because it prevents the student from being overwhelmed with a large slab of theory at one time. Presenting, for example, Vygotsky's theories in a historical context followed by presenting his theory from a pedagogical context allows a young teacher-in-training to absorb the nuances of his ideas for long-term keeping rather than short-term test cramming.
Part Two works decently, but I think that Follari tries too hard (but valiantly) to condense the theories down while simultaneously keeping as many details as possible. Consequently, all of the details of, for example, High Scope are there, but little explanation is given to secure a firm understanding of it. These chapters go by a bit too fast for a novice. It's okay for a veteran teacher, but a new one needs a little more slowness and gradual detail...more hand-holding.
Part Three is only eight pages. It could have been integrated into Chapter One possibly.
On the whole, we get exactly what the title tells us: theory. I find it somewhat refreshing to read it without context, but, again, an undergraduate may need more practical meat to chew on. I think this book would make a good supplementary text rather that the anchoring textbook of an undergraduate introductory early childhood class. I would instead check out books by George S. Morrison, Feeney/Moracik, Jo Ann Brewer, and Robert Berk.
Valiant Effort, though:)
