Qualities of Computer
Science text book
How to use the text
books:
1.
The text books is valuable only when it is
used properly. The teacher’s work is not to transfer the contents of the text
books into the heads of pupils.
2.
The text is one of the sources of
instructional material.

It is used as an aid in teaching, not a
substitute for teaching.
4.
The text books is everything for an average
teacher. Experienced teacher depends less on his text books.

Use of text books inside and outside
class room
Introduction:
The text book is one of
the important aids in the teaching learning process. The Oxford English
Dictionary defines textbook as “A tool used as a standard work for the study of
a particular object.”
The text book should contain the
following tools,
¨
Study Questions
¨
Scenarios
¨
Skill Guides
If
any of these are missing, then it must be provided to the students in the form
of notes.
Use of textbooks:
The textbooks are used for both the
teachers and students in the following ways.
Role of textbooks inside the classroom
for Teachers:
When the textbooks are used inside
the classroom the teacher should know how much of what to be taught is in the
textbook and how well is the plan and sequence of the book matches with the way
the class is to be developed.
¨
It is used in giving
practical work and assignments to the students.
¨
It is a guide and
support for the teachers who are inexperienced and unsure of their knowledge
¨
It is used to give
correct decision during the discussions in the classroom
¨
In giving exams and
tests to evaluate the students.
¨
In reading a lesson in
advance before teaching to the students in advance.
¨
To evaluate the answers
when the teacher is not sure about the correct answer.
Role of textbooks
inside the classroom for Students:
The students use the textbooks to
¨
Get the subject matter
easily.
¨
confirm the subject
matter taught by the teacher at that time
¨
clear the doubts
¨
understand easily the
content with the diagrams and pictures given
¨
express the subject
matter easily without any difficulty
¨
Revise the lessons
thoroughly at the end of the year.
Role of textbooks
outside the classroom:
The textbooks are used outside the
classroom in the following ways,
¨
Students can revise the
lessons taught in the classroom when they come home
¨
When the assignments
are given by the teacher, the students can seek the help of textbook
¨
The teacher, before
taking class can collect materials in advance
¨
Mistakes committed by
the students while taking class during teaching can be corrected in their
houses with the help of text books
¨
The exercises and
questions given at the end of the lesson motivate the students to learn even if
they are not in the classroom also.
¨ This
is a great boon for the students who do not come to the school for one or more
days. Because they can study the lessons taught on those days from the textbook
by being in their home even.

Digital library
is a library in which collections are stored in digital formats and accessible
by computers. The digital content may be stored locally, or accessed remotely
via computer networks. A digital library is a type of information retrieval
system.
Advantages
·
Used to store much more
information, simply because digital information requires very little physical
space to contain it
·
The cost of maintaining
a digital library is much lower than that of a traditional library
·
Digital libraries may
be more willing to adopt innovations in technology
·
There is no physical
boumdary - people from all over the world can gain access to the same
information, as long as an Internet connection is available.
·
People can gain access
to the information at any time
·
The same resources can
be used simultaneously by a number of institutions and patrons.
·
The user is able to use
any search term (word, phrase, title, name, subject) to search the entire
collection.
·
Digital libraries can
provide very user-friendly interfaces, giving clickable access to its
resources.
·
Certain characteristics
of objects, primarily the quality of images, may be improved.
·
Digitization can enhance legibility and remove
visible flaws such as stains and discoloration.
·
On the Internet, the
use of a digital library is enhanced by a broadband connection such as cable
modem or DSL.
An e-book (short
for electronic book, also written eBook or ebook), also
known as a digital book, is an e-text that forms the digital media equivalent
of a conventional printed book.
An E-book, as defined by
the Oxford Dictionary of English, is "an electronic version of a printed
book which can be read on a personal computer or hand-held device designed
specifically for this purpose".
E-books are usually read on dedicated hardware
devices known as e-Readers
or e-book devices. Personal computers and some cell phones can also be
used to read e-books.
Availability
- There are over 2
million free books available for download.
Portability and Storage - An e-reader can potentially contain thousands of e-books, limited only
by its memory capacity
Language Accessibility - E-book websites can include the
ability to translate books into many different languages
E-Reader Attributes- Depending on the device, an e-book may be readable in low light or even
total darkness, uses Text-to-speech software to
read the text etc
Costs - The electronic texts are
generally cheaper.
Security - e-books can be backed up to
recover them in the case of loss or damage
Environmental Concerns - The production of e-books does not consume paper, ink, etc
Important library
resources for computer science

are essential for meeting individual needs in reading for presenting different
points of view and providing rich background of understanding of the people,
the processes and the places, so essential in computer science introduction.
1.
Text books
A number of good text
books in computer science are available in the library. New and revised

level books for teachers, teacher’s guide, information of modern inventions
¨ There should be books on
the methods of teaching computer science
¨ There should be
encyclopedia and reference books
¨ There should also be
books for students for practicals in the library
