Acknowledgement We are living in the 21st century. This is the age of Information and Communication Technology (ICT). ICT has become an integral part of our daily life. It facilities the business professionals, academicians, students, banking and other sectors. It has become a fundamental right of children to get computer education. They have to get the basic to advance knowledge of computer to cope the changes in future. The Government of Nepal has prescribed the syllabus and course outline for the computer education from primary to higher secondary level. Students are not able to get quality computer education due to the lack of quality text books and the limited access to the computer system in schools. To address this scenario, I have developed the complete series of computer book with name Oasis Radiant Computer Science from grade I to grade XII. I have devoted more time for the research and development for the preparation of this book. It provides a comprehensive and balanced coverage at the CDC syllabus. It is possible due to the comprehensive support of my colleges, family members, students and the teachers. I would like to acknowledge all who have directly or indirectly encouraged me to prepare this book. Specially, my thanks go to the students and teachers of different schools for their regular interactions and inspirations to prepare this book. In the same way my thanks go to my parents Tek Nath and Chisa Maya Adhikary, family members Lachhima Adhikary, Jagan Adhikary, Sarashwati Adhikary and lovely kids Samridhi, Sampada, Prasamsha, Ballavi, Ragavi, Suyash and Suyasha Adhikary for their valuable contribution to prepare this book. I must give thanks to OASIS PUBLICATION family for their innovative help to prepare and publish this book. Finally, all the suggestions and comments are acknowledged. Thanking all. Er. Shankar N Adhikary Tarkeshwor, Kathmandu [email protected]
Oasis Radiant computer science Grade One 5 1 Background UNIT Mr. Tek Nath Adhikary is 70 years old. He belongs to a middle class family. He was a teacher of primary school when he was thirty. Now he is a social worker and a teacher of "Praud Shikshya". He always talks about good and moral education. Most of the time he talks about practical-based technical education. His son is a computer engineer. His granddaughter is a doctor. His grandson is studying computer engineering. The grandson and the grandfather are very good friends. On Friday morning both grandfather and grandson were talking
6 Oasis Radiant computer science Grade One to each other. They were talking about the progress of "Praud Shikshya". Grandson : How are your students grandfather? Grandfather : They are fine. But I am a bit discouraged to teach them. Grandson : Why grandpa? Grandfather : I think, they are bored and facing difficulty to learn from one way teaching using same type of teaching and learning technique. Grandson : What do you mean, grandfather? Grandfather : I am the only one teacher. I always use the
Oasis Radiant computer science Grade One 7 same books and similar types of lessons with same teaching method. I think, they are not very interested to learn. They want new way of teaching, training materials and technology to support learning. Grandson : You are the role model for us. You should not be discouraged. Can we help you out?
