The document discusses the qualities of a good science textbook. It outlines several important criteria for evaluating textbooks, including content, organization, literacy style and vocabulary, illustrations, teaching aids, and mechanical makeup and appearance. Specifically, it states that the content should be appropriate for the age and experience of students, concepts should not be too complex, and statements must be accurate. It also emphasizes that the organization of topics should follow a logical psychological sequence and cover the entire syllabus. Illustrations should be clearly drawn and diagrams carefully made to add teaching value. A good textbook also includes features like a glossary, activities, and comprehensive indexing to aid teaching.

CHARACTERISTICS

7. Besides there characteristics, the UNESCO

writing text –books in U.S.S.R and other countries.

and practice .The pupils should be equipped
with ‘know – how ‘utilizing the knowledge in
everyday life.
 The whole content of the text book should be
aimed at shaping the integrated modern
scientific outlook which ensure success in
maintaining scientific knowledge and solution
of the problems of virtual issues .The content
should be simple ,brief, exact ,definite and
alienable

8. .
CONCLUSION
The books are important (too) in the hard of a
teacher .It helps student to how and what they learn to achieve

mechanical makeup and author ship.
