We rely on computers for most of our daily work. As computers are a daily utility, they have gained immense importance in day-to-day life. In the technical world, not knowing about the computer is nothing less than illiteracy. Knowing about computer and its uses are no more a luxury but a necessity. By computer education, we mean, gaining the know-how of the basic concepts related to a computer and gaining the basic knowledge of computer operation. Learning about the computer basics followed by a practical experience of using a computer is the key to computer education. As computers are widely used today, acquiring computer education is the need of the modern times. Keeping in mind the increasing need of computer, computer.com, a series of 5 books from class 1 to 5 has been written with a focus to impart knowledge about computers to young minds. This series will help the teachers to make the children computer friendly according to the level of their knowledge and help them acquire computer technology skills as required by the curriculum of various boards. These books are based on new N.C.E.R.T. guidelines and on CCE pattern. Purpose of this Manual There is a Teacher’s Manual for each chapter. Each chapter of the Teacher’s Manual contains an overview of the chapter in the text. This is a brief summary of the ideas and why they are included in the text. This Teacher’s Manual is for those teachers who face the day-to-day challenge of helping a wide range of students to become more computer literate. It will give you a great deal of help if you are teaching computers. This manual is also designed to help students to become more independent and self-sufficient. It is designed to encourage them to take more responsibility for their own learning. The book can make a major contribution towards preparing students for life in their Information Age. Guided Discovery-based Learning The teacher should give their students a discovery-based learning. Compared with many other subjects, Computer Science is not straightforward to teach. One reason for this is the general nature of the computer field. The computer field is changing very rapidly. The computers nowadays are available at your schools or any working place, 20 years after the existing technology would be Computer.com 3 Introduction overpowered by the superior technology. This suggests there must be strong focus on learning to learn and understand the operating of computers. And the process of transformation should be to learn the latest computer available for learning. In addition, you may want to assign quite a number of the activities at the end of the chapters as homework, and make use of this in assessment. Purpose The key idea behind our teaching is that we are educating the people who will create the future. We provide an education in Computer Science that will retain its value throughout the career of a person, in the presence of technological change. We emphasise the principles which underlie the construction and the analysis of computing systems. We strike a balance between theory and applications, and we include in our curriculum appropriate elements of recent research. We expect our computer literates to play leading roles in industry, the professions and government. Rather than just cope with the future, we expect our computer literates to create the future. Are You a Smart Person? One of the major goals of a teacher is to help students acquire a more realistic understanding in the course contents. The teacher should make the students to say and believe: 1. “I am better at solving some types of problems than others. I am smart enough to get better at solving any type of problem that I care to spend time on.” 2. “I regularly encounter and solve problems at home, at work, at play, and at school. Problems are everywhere. Computers help me out solving the problems. I am either working at school or I am working outside of school. Both types of learning are very important to me.” By the time students get to the classes you teach, they have repeatedly demonstrated that they are quite smart and that they are good problem solvers. They have successfully coped with life in our society and with our school system. One of the things that we know about problem solving is that success breeds success. Our school system and our society tend to reward people who are good at solving school and non-school problems. This positive feedback promotes putting in the time, energy, and thought needed to become still better at problem solving. You, as a teacher, have to create a learning environment that strongly encourages your students to become better problem solvers. One starting point is to help all Computer.com 4 Introduction of your students to realise that they are already quite good at solving problems. All of your students are “smart”. Coordination with Computer.com books An underlying theme in every course should be “How to learn?” A computer book provides an environment in which students can explore their own learning styles and work on learning process. Here are a few examples of types of questions you can explore with your class that will help relate the chapter materials to several general types of computer literacy courses. 1. Computer applications. A. What features are common to all word processors (or, to some other generic piece of software such as a database)? To what extent does learning one of these features on one particular piece of applications software carry over to more easily learning the similar feature on a different piece of applications software? B. When you are learning to use a word processor (or other generic software) what is your preferred style for learning? For example, do you like to experiment on your own, have the teacher explained it, read a book, watch a fellow classmate do it, or what? Is your preferred learning style the same as for all other students in the class? Does it work equally well for all pieces of applications software? C. In what sense is, “Use a word processor,” a good strategy for solving a writing problem? The same type of question can be asked for other types of applications software and other problems. 2. Computer programming A. What learning strategies do you use in learning a new “primitive” in a programming language? B. How do you study for a programming test? Is it the same way that other students in the class study for programming tests? Is it the same way you study for a test in other courses? 3. Computer awareness, including exploration of social and vocational issues. A. What came before the information Age? What do you think will come after the information Age? How do such changes affect people? How do they affect you? B. How can you tell if a person is computer literate? Are you a computer literate? Why would a person have to be computer literate? Computer.com 5 Introduction TEACHING PROCEDURES 1. Begin by making sure all students have their books. Ask students to recall what they have learnt from the previous lesson. Provide a long wait time. Then accept several students’ responses. (Be aware that a long wait time allows students to practice Higher-Order thinking skills, rather than just saying the first thing that pops into their conscious mind.) 2. Display Chapter to the student. Explain the chapter to the student in very easy to understand way. Help students get started in understanding that chapter. Have them write on some important idea that they remember from the chapter. Have your students spend a couple of minutes reading the Chapter. 3. Assign the activity at the end of the chapter. 4. Closure. Near the end of the period, students get to think about some of the important ideas that have been covered in that day’s discussions and readings. Each student is to decide on one idea that he/she felt was particularly important. As time permits these ideas can be shared by the whole class, in small groups, written down, or merely thought about at a personal level. Student Learning Indicators Students were actively engaged and had fun. An atmosphere of discovery-based learning was created and maintained. You were satisfied with how well the class was going on. You have learnt some new things about your students and/or yourself. BOOK - 1 1. MACHINES AND COMPUTERS Overview : Machines are man-made things. They work very fast and save time.

Calculations Computer.com 2. 16 3. 0 and 1 123 4. 8 Book - 8 Answer Time : A. 1. The digital computers accept all the data in the form of binary numbers, of using 1 and 0 which represent on and off respectively. Modern computers work with the collection of 1 and 0 number. A single pair of 1 and 0 is called bit which is an abbrevation for binary digit. A binary number like 1100 has 4 bits 110011 has 6 bits and 11001100 has 8 bits. 2. The basic difference between analog and digital computers is the type of data they process. Digital computers process data which is binary, i.e. in the form of 0 and 1. Analog computers operate on mathematical variables in the form of physical quantities that are continuously varying. 3. The octal numeral system, or oct for short, is the base-8 number system, and uses the digits 0 to 7. Octal numerals can be made from binary numerals by grouping consecutive binary digits into groups of three starting from the right. For example, the binary representation for decimal 74 is 1001010. 4. 5. A string is a group of characters (either letter or digits) written one after another. For instance, 734 is the sting of 73 and 4. Similarly, 2C8A is sting of 2, C, 8 and A. Number systems are the technique to represent numbers in the computer system architecture, every value that you are saving or getting into / from computer memory has a defined number system. Computer architecture supports following number systems. i) Binary Number System : Binary is a two digit numerical system which computers use to store data and compute functions. The reason for which computers use the binary system is that digital switches inside the computer can only be set to either on (or) off which are represented by a 1 or 0. ii) Decimal Number System : The Decimal number system is the system which is composed of numbers from 0 to 9. It has ten digits and hence the base of this system is also 1230, 7890, 45610, etc. are examples of Decimal number system. iii) Octal Number System : The Octal number system has digits starting from 0 - 7. The base of this system is 8. 1238, 5648, 2368, etc. are examples of Octal number system. iv) Hexa Decimal Number System : The Hexa decimal number system are 0 to 9 digits and characters from A - F. A represents 10, B represents 11, C represents 12, D represents 13, E represents 14 and F represents 15. The base of this number system is 16. Computer.com 124 Book - 8 6. A byte is used for holding a character code. There are about 105 to 108 keys on the keyboard considering of alphabet, digits, symbols and punctuation marks, etc. All these characters must be digitized, i.e., expressed in 0s and 1s. Each of these are expressed in a given specific number code and binary system. Each number code is organised in the group of 8 bits is called a byte. 7. An easy method of converting decimal to binary number equivalents is to write down the decimal number and to continually divide-by-2 (two) to give a result and a ramainder of either a "1" or a "0", until the final result equals zero. So, for example "Convert the decimal number 29410 into its binary number equivalent". Start picking the remainder from the last, that is 1, then seocnd last remainder 0 and then 1, 0, 1, 1, 0, 0, 1, 0, 1. Join them together as 101100101 which is the binary number. 2 2 2 2 2 2 2 2 294 147 73 36 18 9 4 2 1 1 0 1 0 0 1 1 0 1 Activity Time : Student’s Activity 3.
