Pedagogy of teaching - Computer Science Text books and computer science library
- 1. Text books By Dr. I. Uma Maheswari iuma_maheswari@yahoo.co.in
- 2. Uses of Computer Science Text Book • The text book occupy a central and prominent place in any scheme of teaching learning process. • It helps the teachers and taught to get acquainted with the limits and boundaries of the subject matter being taught or learning experiences to be gained with respect to a particular grade or class.
- 3. • The subject mater related to a particular subject and written by experienced teachers and eminent authors is readily available to the students and teachers in the form of text books. • The text books are very much useful in saving time and energy of the students as well as the teachers. • They are also helpful in maintaining the uniformity of the standard not only within the different sections of a school but within the different schools belonging to a region, state or country.
- 4. Qualities of Good Computer Science Text Book • Programming languages are important for a computer text book. It should set out to introduce the basic ideas associated with computers that have relevance to education. • It should have explanation about the hardware components and its usage. • It should have explanation about computation and practical techniques for their implementation and application.
- 5. • It should have a frequent description about the systematic study of algorithmic processes that describe and transform information. • It should give idea about the sub – fields of computer education. • The focus of computer science, text is more on understanding the properties of the programs used to implement software such as games, and web – browsers and using that understanding to create new programs or improve existing ones.
- 6. • It should differentiate a general computer science from the vocational areas like information technology or artificial intelligence etc. • As a discipline a computer science text must have a range of topics from theoretical studies of algorithms and the limits of computation to the practical issues of implementing computing systems in hardware and software. • It should create a new topic.
- 7. • It should have significant scientific knowledge. • It should have a good introduction and survey of a topic. • A good text book must address to educational pedagogic issues. • It should have description about the use of computers effectively and experiment with new technologies for class room purposes.
- 8. • Computer Science books must provide the theory and practice of computer education and it should examine the conceptual, historical and social contexts of computer – based emerging technologies and the implications of these for the every day classroom practice and institutional climate building.
- 9. Use of text book in and outside the classroom • The main purpose of every computer text book is to help teachers, teacher educators, student teachers, curriculum planners, course designers and educationalists as a reference book. • It must explain the practical ways to use computer technology to increase the efficiency and effectiveness of the educational process and also to develop the creative uses of new technologies in institutions of learning and in community settings.
- 10. • Books should move from mere explanation of fundamental ideas to the actual practice of computer education • A large number of people, students and teachers in the public, colleges and universities believe that the teaching and technology are independent and are in opposition to each other. • A computer text should serve the purpose in and outside the class rooms.
- 11. • In the educational institutions the instrumental status of the computer technology is conceived as a teaching aid and merely as an external material object projected in time and space. • Computer books should provide a variety of learning opportunities to the students in integrating new technologies in their class room and institutional pedagogic activities for the purpose of enhancing students learning.
- 12. • The effective application of the scientific knowledge associated with computers has greatly transformed our perceptions, conceptions, world views, perspectives etc. • A human thought is possible without recognizing the importance of computers in the day to day activities. • It is imperative to understand the fundamental ideas that created such a wonderful expression of human intellect. • Every computer science book should serve the purpose of making the society understand “the wonder” computers and its technology to reveal the inherent beauty and aesthetic expressions and intellect of the human endeavour.
- 13. Criteria for evaluation of computer Science text book 1. Accuracy 2. Authority 3. Currency 4. Uniqueness 5. Quality of writing 6. Purpose of the content 7. User friendliness
- 14. Accuracy • A computer book should have the information in accuracy. • A resource may be checked against other resources for accuracy. • It is to analyze whether the author has written all important information about a computer and its technologies.
- 15. Authority • It is to evaluate whether the matters or information presented has organisation and expert behind it. • Does the author has standing in the field? • Are sources of information stated?
- 16. • Is the information verifiable? • Can the author be contacted for clarification or to be informed of new information? • Authority is proved in all these questions.
- 17. Currency • A book should have updated informations. • It commitment and its stability should be uncomparable. • The books must have current informations.
- 18. Uniqueness • A book should have all the features in a original manner. • It should prove its uniqueness by presenting rare and complicated informations in an easy way.
- 19. Quality of writing • The text should have well written. • The quality of writing is important for the content to be communicated clearly.
- 20. Purpose of the content • The content or resource should fulfil the reader. • The purpose needs to fit the intended audience and satisfy their needs.
- 21. User friendliness • The information given in the book must be easy and clear to understand and use. • It must give a satisfaction and confident to the reader.
- 22. Value of computer science library • A computer science library is a collection of subroutines or classes used to develop software. • Libraries contain code and data that provide services to independent programs.
- 23. • This allows the sharing and changing of code and data in a modular fashion. • Some executables are both stand a lone programs and libraries, but most libraries are not executables. • Executables and libraries make references known as links to each other through the process known as linking which is typically done by a linker.
- 24. • As on 2009 most modern software systems provide libraries that implement the majority of system services. • Such libraries have commoditized the services which a modern application expects to a get provided. • Most code used by modern applications is provided in these system libraries. • A computer library consists of a large number of books and journals on computer science and computer related areas.
- 25. Digital library • A 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 compute networks. • A digital library is a type of information retrieval system.
- 26. • A correct definition for digital library – An organisation which might be virtual, that comprehensively collects, manages and preserves for the long term rich digital content and offers to its users communities specialized functionality on that content of measurable quality and according to codified policies. • The term digital library is diffuse enough to be applied to a wide range of collections and organizations but to be considered a digital library an online collection of information must be managed by and made accessible to a community of users.
- 27. Advantages • No physical boundary – The user of a digital library need not go to the library physically. • Round the clock availability • Multiple access – same resources can be used simultaneously by number of institutions.
- 28. • Information retrieval – The user is able to use any search terms like a word, phrase, title, name, subject to search the entire collection. • Preservation and conservation – Digitized is not a long term preservation solution for physical collections, but does succeed in providing access copies for materials that would otherwise fall to degradation from repeated use.
- 29. • Space – Traditional libraries are limited by storage space, digital libraries have the potential to store much more information, simply because digital information requires very little physical space to contain them and media storage technologies are more affordable. • Added value – 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.
