INTRODUCTION

        Publishers make available not only up-to-date and attractive science textbooks but a good variety of books for supplementary reading, periodicals and weekly newspapers that are devoted exclusively to science. Printed materials being essential part of science curricula play a key role in effective teaching and learning.
  
          The text book is the most widely used of all teaching instruments. Few teachers attempt a programme without one and many administrators require that one be used. Anytool used as extensively as this is certain to be misused on occasions and be subject of harsh criticism in consequence.
         
          According to Bacon Paul,-“A text book is a book for classroom use carefully prepared by experts in the field and equipped with usual teaching devices.”


OBJECTIVES OF A GOOD SCIENCE TEXTBOOK

         The following objectives of a good science textbook :

·       To facilitate the learners to understand exactly the various concepts and fundamental principles of science in a simple and scientific way.
·       To develop scientific attitude , scientific skills and a wide variety of the applications of the scientific knowledge among the students.
·       It should supplement and enrich classroom learning.
·       It should help pupils in doing home assignments.


QUALITIES OF A GOOD SCIENCE TEXT BOOK

The following are the impart qualities of a good science text book:-
   
Ø The Author
Ø Mechanical features
Ø The subject matter


THE AUTHOR

      A good book mainly depends on the experience and the knowledge of  the author. The author should have the reasonable experience in teaching of that subject on which he is going to write.

Mechanical features of the book

          It involves paper quality, binding, printing etc. All these features are also important for a book and these features should be made attractive and according to the age of students. It is useful for the understanding of the learners to provide diagrams, sketches etc clearly, wherever necessary.

Subject matter

·       The textbook should cover the entire syllabus prescribed, without leaving even a single bit of information.
·       The content should be arranged sequentially and systematically based on the psychological principles.
·       Adequate introduction for every lesson is needed.

·       The style of the book, the get up, etc should be of good standard.
·       Individual differences should be taken into consideration, while preparing a textbook.

PUPIL’S WORK BOOK

                     Science work book is an adjunct to science text book. For effective learning, pupils should have opportunities for practicing what they have learnt. Pupil’s work book in fact a practice material for pupils, the content of which is arranged in the order of the text book on which is based. A work book contains summary of each chapter of the textbook, exercises of different kinds , key to exercises and suggestions for practicals, assignments and improvisation.

Advantages

·       Work book supplements classroom learning.
·       It  promotes  self learning and self assessment.
·       It provides for working out different types of assignments.
·       It gives practice of classroom learning and thereby reinforces learning.
·       It promotes scientific thinking.


TEACHER’S HAND BOOK
Or
GUIDE BOOK FOR TEACHERS

            Teacher’s hand book is an excellent reference material for teachers for effective science teaching. In our state, it is prepared by the SCERT along with text books prepared by them. It contains summaries of chapter in the science text books, conceptual development of each topic, list of instructional objectives and specifications, explanation of significant technical terms, learning activities, precautions to be taken while attempting  demonstrations, teaching aids to be used, assignments of various kinds, evaluation tools, co-curricular activities that can be organized, seminars, projects etc to be organized and suggested references for teachers and pupils. In short, t6eacher’s hand book is a resource material for teachers.

    Advantages
·       It equips the teacher with sufficient theoretical knowledge and practical suggestions of what is to be taught.
·       It provides suitable learning experiences for different instructional situations.
·       It helps teachers to adopt appropriate methods and approaches of teaching.
·       It helps the teacher prepare various instructional materials.
·       It helps the teacher evaluate learning using relevant and standard tools of evaluation.

REFERENCE BOOKS

           Reference books  are used to find factual information on a subject and are not. Usually read all the way through or chapter by chapter. In a k-12 library, refer- book are usually located in a special reference collection areas and cannot be checked out. Reference book include dictionaries, encyclopedia, thecauei, almanacs, an comparison, a reference book or reference only book in a library is one that may only be used in the library and not borrowed from the library.

SOURCE BOOK

               The term sorce book is used to describe many different kinds of books such as collection of core articles, bibiliographies, biographies, printed archival sources, directories, and so on. These seems to be no conschsus in the application of the term.


CONCLUSION

                    A good science text book  should help to form correct understanding of basic concepts and principles of science. Now a days text book has become, a course of study, a set of unit plans and a learning guide as well. A text book is an economical device for teachers and students as it gives direction and saves time and energy. Also hand book is excellent reference material for teachers.
