A preface from author Kelvin Seifert about his intentions in including his Educational Psychology textbook in the Global Text Project (GTP)

Dr. kelvin seifert: why i wanted this book to be part of the global textbook project

I have taught educational psychology to future teachers for nearly 35 years, during which I used one or another of the major commercial textbooks written for this subject. In general I found all of the books well-written and thorough. But I also found problems:

  1. Though they differed in details, the major textbooks were surprisingly similar in overall coverage. This fact, coupled with their large overall size, made it hard to tailor any of the books to the particular interests or needs of individuals or groups of students. Too often, buying a textbook was like having to buy a huge Sunday newspaper when all you really want is to read one of its sections. In a similar way, commercial educational psychology textbooks usually told you more than you ever needed or wanted to know about the subject. As a format, the textbook did not allow for individualization.
  2. Educational psychology textbooks were always expensive, and over the years their costs rose faster than inflation, especially in the United States, where most of the books have been produced. Currently every major text about educational psychology sells for more than USD 100. At best this cost is a stress on students' budgets. At worst it puts educational psychology textbooks beyond the reach of many. The problem of the cost is even more obvious when put in worldwide perspective; in some countries the cost of one textbook is roughly equivalent to the average annual income of its citizens.
  3. In the competition to sell copies of educational psychology textbooks, authors and publishers have gradually added features that raise the cost of books without evidence of adding educational value. Educational psychology publishers in particular have increased the number of illustrations and photographs, switched to full-color editions, increased the complexity and number of study guides and ancillary publications, and created proprietary websites usable fully only by adopters of their particular books. These features have sometimes been attractive. My teaching experience suggests, however, that they also distract students from learning key ideas about educational psychology about as often as they help students to learn.

By publishing this textbook online with the Global Textbook Project, I have taken a step toward resolving these problems. Instructors and students can access as much or as little of the textbook as they really need and find useful. The cost of their doing is minimal. Pedagogical features are available, but are kept to a minimum and rendered in formats that can be accessed freely and easily by anyone connected to the Internet. In the future, revisions to the book will be relatively easy and prompt to make. These, I believe, are desirable outcomes for everyone! --Kelvin Seifert

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

Mostly, they use nano carbon for electronics and for materials to be strengthened.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
