INTRODUCTION
Text book that are intended to be used should be useful for the students as well as teachers. They should be so designed that on the one hand they may be written according to the psychological requirements of the students and on the other they should serve the purpose of the teacher who wish to impart knowledge to the students in a successful and interesting manner. The size of the books should be handy. It should be possible for the students to carry them properly. They should not be bulky. This is especially true about books intended for the primary classes. Printing and getup of the books should be interesting and attractive. They should be printed in the letters that they do not require strain on the eyes of the students. On the other hand they should be correctly and neat printed. The exterior of the picture should be attractive. If the exterior is attractive, students would like to carry them and keep them. This is true of the books intended for primary classes. They should serve the purpose of the subject matter as well as the aims and objects of the teaching. Various score cards and check lists have been devised to make the selection of text books as objective as possible.





CONTENT
In the teaching- learning processes, the text book occupies and important place. There is a saying “As is the text book, so is the teaching and learning”. A good text book can even replace class room teaching. The science text book should aim at aiding the pupils in the development of their personalities, in developing open mindedness, developing appreciation and understanding of nature and not merely stuffing their minds with facts.
Characteristics of a Good Text book:
Thurber and Collette (1964) suggested six criteria for choosing a good text book. They are as follows.
1.      Content
2.      Organaization
3.      Literary style and vocabulary
4.      Illustrations
5.      Teaching aids
6.      Mechanical make up and appearance
1. Content:
              The content of text books for any one subject matter field is remarkably uniform, about 85 percent of the content being common to all of them.
·         The content should be appropriate for the age level and experience backgrounds of the pupils.
·         The concepts should not be too complex for maturity of the pupils.
·         The content should be consistent with the pupil’s needs and interests.
·         The content should conform with any state or local syllabi that must be followed.
·         The statements must be accurate.
·         The content should reflect the unknowns and uncertainties in science as well as the knows.
2. Organaization:
                Two distinct types of organaization are seen in school science books.
a)      In the first type using local organaization, concepts and principles are developed in the way that a well educated person must organize them which is usually seen in college texts and in high school physics and chemistry texts.
b)      In the second type using psychological organaization the attempt is made to present the material in the order that would be most meaningful to the pupil’s whom it is designed which is seen in general science and biology texts.
3. Literary style and vocabulary
                    Literary style much to do with the readability of the book. Although style is difficult to judge, some points to be looked for are:
a)      Length of sentences.
b)      Directness of sentences.
c)      Number of ideas per sentence
d)     Use of lead sentences or paragraphs.
e)      Presence or absence of irrelevant thoughts.
f)       Continuity of thought.
While evaluating a text book the teacher must decide whether or not the vocabulary is excessive or in appropriate. Text book should be easy to read.
4. Illustrations:
a)      The quality and quantity of illustration should be considered.
b)      Photographs should be clearly reproduced.
c)      Diagrams should be carefully made attractive.
d)     Color in the illustrations adds to eye appeal and when properly used has considerable teaching value.
e)      The recently introduced transparencies made on plastic sheets are excellent teaching aids but because of cost it can only be used in small quantities in any one book.
f)       Photographs should have relation with content in the text.
5.  Teaching aids:
·         The table of contents and index should be comprehensive.
·         Glossary should be included.
·         Activities should be given at the end of a chapter.
·         Activities should be closely related to content.
6.Mechanical make-up and appearance:
·         Artistic cover.
·         Durability for binding.
·         Size of the book.
·         Good quality of paper.
·         Length of line and size-legible.
·         Attractive over-all experience.
·         Cover design and color should be appending.
·         Ample space to be left between lines to provide for easy in reading.

Qualities of a good text book
1.      The author: A good text book is judged, at face, by the author, his qualification and experience.
2.      Mechanical features of the textbook.
a)      The print and paper used and the binding of the textbook should be attractive. It should be hard and durable.
b)      The printing should be clear, legible and opportunity spaced.
c)      The size of the print, the language and experiments discussed should suit the age of the child and standard of the child.
3.      The subject matter its nature and organaization
a)      The subject matter should be developed as far as possible in psychological sequence. Care must be taken of the mental growth and interest of pupils.
b)      There should be consistency of the subject matter and the text book should satisfy the objectives of science teaching.
c)      Each chapter should begins with a brief introduction and end with a summary.
d)     Subject matter should lead to the inculcation of science attitudes, disciplinary and cultural values.
e)      Each chapter should contain assignments at the end.
f)       During treatment of subject matter, numerical examples should find place where necessary.
g)      Headings and subheadings are given in bold letter.
h)      Each text book should contain detailed table of contents and an index.
                                      Besides these characteristics, the UNESCO planning mission has given some principles of writing text books in U.S.S.R and other countries they are as follows.
·         It should be first of all according to the requirements of the syllabus. It should also help in the improvement of the syllabus.
·         The facts, concepts etc, should be modern and with in the comprehension of the pupils.


VOGEL’S CRITERIA
                                                                   Another kind score card, designed to speed up the process of evaluation, is the “spot check” method illustrated by Vogel Louis F known as ‘Vogel’s spot check evaluation scale’. Cited Thurber and Collete (1964), on this score card, each item has been assigned a maximum value of two points. The value of each item under each head is totaled against the part score. The part scores of each head are then counted and the over all value is written against the space for partial score.

FOG INDEX
                                                                 In linguistics, the gunning fog index is a readability test for English writing. The index estimates the years of formal education a person needs to understand the text on the first reading.
                                                        The fog index is commonly used to confirm the text can be read easily by the intended audience. Texts for a wide audience generally need a fog index less than 12.
Texts requiring near universal




Fog index

Reading level by grade
17
College graduate
16
College senior
15
College junior
14
College sophomore
13
College freshman
12
High school senior
11
High school junior
10
High school sophomore
9
High school freshman
8
Eighth grade
7
Seventh grade
6
Sixth grade

                                               The gunning fog index is calculated with the following algorithm.
1.      Select a passage (Such as one or more full paragraph) of around 100 words. Do not omit any sentences.
2.      Determine the average   sentence length. (Divide the number of words by the number of sentences) ;
3.      Count the “Complex” words: those with three or more syllabus. Do not include proper nouns, familiar jargon or compound words. Do not include common suffixes. (Such as –es,-ed or –ing) as a   syllable;
4.      Add the average sentence length and the percentage of complex words; and.
5.      Multiply the result by 0.4.
The complete formula is:
                0.4[(words/sentences)+100(complex words/words)]
Limitations:
While the fog index is a good sign of hard to read text, it has limits. Not all complex words are difficult. For example, “interesting” is not generally though to be a difficult word, though it has four syllables. A short word can be difficult if it is not used very often by most people. The frequency with which words are in normal use affects the readability a text. Some continue to point out that a series of simple, short sentences does not mean that the reading is easier. In some works such as gibbon’s. The history of the decline and fall of the Roman Empire; the fog scores using the old and revised algorithms differ greatly.




CONCLUSION
                                                    According to the American Association for the Advance of science (AAAs), there is evidence that science teachers use textbooks as the primary teaching tool. In order for science text books to fulfill their functions as primary educational resources, they must have a certain set of qualities and characteristics. Text books that are poorly designed can inhibit learning and turn children off of subjects they might otherwise embrace. The whole content of the textbook should be aimed at shaping the integrated modern scientific outlook. Which ensures success in mastering scientific knowledge and solution of the problems of vital issues. The content should be simple brief, exact, define and accessible.
