INTRODUCTION In today’s world, the computer has become an indispensable tool. From huge machines weighing several tonnes, the computer has evolved into light, sleek, yet powerful machines that dominate today’s knowledgebased society. Many previously complex and time-consuming tasks have been reduced to the mere touch of a few buttons on the keyboard. Basic computing skills such as word processing are an essential requirement in today’s job market. The Internet has revolutionized the way people communicate and interact. Geographical distances are no longer a constraint for effective business transactions, information dissemination, and interpersonal interactions as distances have been overcome through extensive, intricately-designed communication networks. Today computer science is an academic subject in its own right, governed by scientific and mathematical principles. Due to its increasing importance, computer studies have become an essential part of the education curriculum around the world, including in Pakistan. However, the trend has been to favour Information and Communications Technology (ICT) rather than the science behind computers. ICT in schools usually focuses only on teaching how to use office productivity software such as word processors, presentation software, and spreadsheets. However, as teachers, we should ensure that we teach not only ICT, but also computing, especially in the lower classes. This is an important distinction because ICT primarily involves simply understanding and memorizing commands. As a consequence, many students may get the impression that little creativity is involved in using computers. This may result in students losing interest in what they mistakenly believe to be computing. Students must be introduced to how computers work and be given the opportunity to be creative through computing activities that challenge them to use their logical and analytical skills along with their creativity. Computer science education should be such that students are capable of making a meaningful contribution other to advance our digital society or use digital media optimally in their chosen field of study or work, should they decide to do so in the future. Computer education in schools should equip every child with the basic understanding of how computers work and demonstrate the possibilities of information technology in a knowledge-based society and economy. This has been the rationale for developing the Keyboard: Computer Science with Application Software (Second Edition) series.

About Keyboard: Computer Science with Application Software (Second Edition) Keyboard: Computer Science with Application Software (Second Edition), a series of eight books for Classes 1 to 8, is a comprehensively revised edition of Keyboard: Computer Science with Application Software and carries forward the same interesting and interactive approach that is a hallmark of the series. The series aims to make the study of computer science engaging and interactive for students through a combination of features.

The contents are based on the most recent feedback from teachers and incorporate the latest trends in computer education. We have taken particular care to update facts and figures, and to include the latest advancements in the field of information and communication technology. Thus, trendsetting topics such as social networking and cloud computing have been explained along with devices such as smartphones and tablets. Also, in keeping with the times, there is greater focus on animation and web design. The series introduces the subject in language that is simple and direct. Technical jargon is used only where necessary and all such terms are defined at the end of each chapter. Comic strips, icons, cartoon characters, and illustrations make the learning process an enjoyable experience. This series is an advanced course in computer science designed for those schools that wish to teach creative application software such as Flash, HTML, Photoshop, and Dreamweaver along with the basic concepts of computers, computer programming, and the Internet.

Course Features and Highlights Each chapter in Keyboard: Computer Science with Application Software (Second Edition) starts with an engaging introduction in comic strip format presenting a conversation between two characters, Goggle and Toggle. Goggle represents an average primary and middle school student, while Toggle is an animated laptop and an expert in computer science. Toggle helps Goggle understand all that is taught about computers and computer software in the series. The series has a hands-on approach to learning with text supported by relevant screenshots and plenty of practical exercises. The MS Office screenshots are based on MS Office 2007, with the compact and user-friendly Windows 7 as the operating system.

Update Office 2010 A special feature of the series is the update provided on MS Office 2010. As you are aware, a new interface was designed by Microsoft for their MS Office package, beginning with MS Office 2007. In MS Office 2010, Microsoft has retained the Ribbon interface introduced in MS Office 2007, but has provided some additions, enhancements, and improvements to the feature. Update Office 2010 describes the new or additional features introduced in MS Office 2010 when compared with MS Office 2007. These updates have been placed at the relevant points within the MS Office chapters thus enabling direct comparisons. Students and teachers will thereby have a clear idea of the refinements in MS Office 2010.

Worksheets and Assessment Papers Worksheets have been introduced for Classes I to V, while for Classes VI to VIII Assessment and Comprehensive Assessment papers have been included.

Practice Time, Exercises, and In the Lab The Practice Time feature provides practical exercises after every major topic, in which the student applies the concept(s) learnt in the previous section to solve a practical problem. The detailed solution is given after the question, so that students are able to understand the practical application of a particular concept independently. This frees the teacher from the process of assessing whether individual students have fully understood the concept. The Exercises and In the Lab questions deserve particular mention. The exercises in each chapter include enough theoretical and practical questions for concept application. The In the Lab questions are similar to those under Practice Time except that no solutions are given and the questions are more complex than those found under Practice Time. In both, however, the questions describe a variety of situations across the curriculum thus integrating the use of computers with problem-solving in other subjects areas.

v

The Revision Questions are recommended as a self-assessment tool for the students; for those who would like to attempt the Cyber Olympiad, sample questions have been provided for practice.

Digital Learning Resources The Learning Resource CD for students contains animation, videos, tutorials, and tests. Animation clips offer an audio-visual explanation of technically complex or difficult concepts. Demo videos linked to one of the Practice Time questions in software chapters present a step-by-step audiovisual guide to solving the problem described.

Teaching Resources The teaching resources for the Keyboard: Computer Science with Application software and (Second Edition) consist of Teaching Guides and a Teaching Resource CD. Teaching Guides The Teaching Guide accompanying each Student’s Book is carefully structured to provide useful support to teachers. Each Teaching Guide contains the following: • A lesson plan that details the number of periods recommended for a particular chapter, the topics therein, the expected learning outcomes at the end of each topic, and the digital support available for each chapter. This is intended to assist teachers in overall planning. Teachers should read through the lesson plan before stepping into the classroom or can use the recommendations for creating their own lesson plan. • The complete answer key to the Student’s Book exercises has been given including answers for the In the Lab questions, Worksheets/Assessment papers, Revision Questions, and the Cyber Olympiad Questions. • A set of chapter-wise worksheets follows the lesson plans, and has questions in the form of crossword puzzles, wordsearches, jumbled words, etc. designed to reinforce conceptual understanding. • In addition to the worksheets, a set of chapter-wise test papers has also been provided, which may be used by teachers to create their own assessment papers, or used as they are for classroom tests. Teaching Resouce CD The Teaching Resource CD contains printable reinforcement and assessment materials along with a Test Generator. Printable documents for every chapter include lesson plans, answers to the Student’s Book exercises, worksheets, and test papers. The comprehensive and easy-to-use Test Generator is an effective assessment tool designed to benefit teachers by enabling them to create a variety of test papers. It includes an extensive pool of questions, such as multiple choice, true or false, fill in the blanks, short answer, and long answer questions, as well as lab exercises where relevant. Answers have been provided to enable efficient and effective evaluation. The Test Generator allows the teacher to create test papers for one or more chapters. The Students’ Books, and the accompanying Teaching Guides and digital resources together form a complete package enabling effective teaching.

Continuous and Comprehensive Evaluation Learning takes place in a variety of ways—through experience, making and doing things, experimentation, reading, discussion, asking, listening, thinking and reflecting, and expressing oneself in speech, movement, or writing. All these modes of learning are possible both as individual or group activities. It would thus be advantageous for students to be given the opportunity to participate in as many of these activities as possible.

Continuous and Comprehensive Evaluation (CCE) The primary objectives of this system are (1) to maintain continuity in evaluation and (2) to reliably assess broad-based learning and behavioural outcomes. In this system the term ‘continuous’ is meant to emphasize that evaluation of a student’s progress is a continuous process rather than an event. It is spread over the entire span of an academic session, and means regularity of assessment and unit-testing. It also includes a diagnosis of learning gaps, the use of corrective measures, retesting, and self-evaluation. The term ‘comprehensive’ suggests that the system covers both scholastic and co-scholastic aspects of a student’s growth and development. This system expects involves both formative and summative assessment. Formative assessment is a tool used by the teacher to monitor student progress continuously in a supportive environment. It involves regular feedback, a chance for the student to reflect on his/her performance, seek advice, and improve. If used effectively, it can greatly improve student achievement. Summative assessment is carried out at the end of a course of learning. It measures, or ‘sums - up’, how much a student has learnt from the course. It is usually a graded test, i.e. it is marked according to a scale or set of grades. It has been found that assessment that is predominantly of a summative nature will not by itself yield a valid measure of the growth and development of the student. At best it indicates the level of achievement only at a given point of time. The paper-pencil tests are basically a one-time mode of assessment and to rely on them exclusively to judge the development of a student is both unfair and unscientific. Over-emphasis on examination marks leads students to believe that assessment is different from learning. Besides encouraging unhealthy competition, the reliance on a summative assessment system also results in unnecessary stress and anxiety among learners. The Keyboard: Computer Science with Application Software (Second Edition) series, comprising of Students’ Books, Teaching Guides, and digital resources, includes a number of features that aid both continuous and comprehensive evaluation.

1

CONTINUOUS EVALUATION Students’ Books Beginning of Instruction (Formative Assessment) • The introductory dialogue at the beginning of each chapter between Goggle and Toggle is a starter to the chapter topic and can be employed to test the prior knowledge of students by using the dialogue to ask for possible solutions or an answer to Goggle’s questions. For example, in the following dialogue you can also ask them what the alternative to pressing the Enter key is.

During Instruction (Formative Assessment) The conceptual grasp of students can be assessed during instruction through Practice Time, which has been placed after every major topic in the Student’s Book, by observing how fast they carry out the task as given. A couple of questions may also be added to test their understanding of the concept. For example, in the question below students may be asked if they can use the RT or the LT command in the solution to this question instead of the SETH command.

2

1

End-of-Chapter (Summative Assessment) • At the end of the chapter the student can be tested on acquired knowledge through the objective and descriptive questions in the Exercises section, and on the practical application of concepts through In the Lab questions.

End-of-Unit and Term (Formative as well as Summative Assessment) • Assessment at the end of three or four chapters is facilitated through Worksheets in Classes I to V. • In Classes VI to VIII Assessment and Comprehensive Assessment papers help children familiarize themselves with evaluation patterns.

Teaching Guides The Teaching Guides provide the following support for formative and summative assessment: • Worksheets, one for each chapter, have questions in the form of crossword puzzles, wordsearches, jumbled words, etc. designed to reinforce conceptual understanding. • Test papers, one for each chapter, which may be used by teachers by photocopying them in a larger format for classroom tests.

1

3

Digital Resources The digital support for the series comprises the Learning Resource CD and the Teaching Resouce CD. Learning Resource CD The Learning Resource CD for Keyboard: Computer Science with Application Software (Second Edition) includes: • Animation clips for conceptual topics such as those on operating systems, the history of computers, input and output devices, etc. offer an interesting audio-visual element to technically complex or difficult concepts. There are one or more modules for each such chapter that enable students to reinforce what they have learnt in class. • Demo videos that are linked to one of the Practice Time activities in software chapters (those chapters that describe the features and commands available in a software), and present a step-by-step audio-visual guide to solving the problem described in that particular Practice Time question. One or more objective type question(s) has (have) been introduced at (a) strategic point(s) under the Rapid Round feature during the demo to encourage students to participate in the solution to the problem. These questions could be also be used as a formative assessment tool. Teaching Resource CD Printable documents for every chapter in the form of soft copies of the worksheets and test papers are given for each chapter in the Teaching Guides. The teacher is free to use either version of the worksheets and test papers as formative assessment tools. The Test Generator accompanying the Teaching Resource CD is an effective assessment tool designed to benefit teachers by enabling them to create a variety of test papers. It has an extensive pool of questions including multiple choice, true or false, fill in the blanks, very short answer, and short answer questions, as well as lab exercises where relevant. The Test Generator can be used to create test papers for one or more chapters. The wide variety of objective and descriptive questions makes the tool flexible enough for teachers to employ it either for formative as well as summative assessment. Answers have also been provided for these questions to aid efficient and effective evaluation by teachers.

Comprehensive Evaluation Comprehensive evaluation involves, as explained above, both the scholastic and co-scholastic aspects of a student’s growth and development. It aims to assess the student not only in the area of pure knowledge but also in the areas of their analytical and creative ability, as well as in their general attitudes and aptitudes. The key features in Keyboard: Computer Science with Application Software (Second Edition) have been designed to provide both scholastic and co-scholastic development.

Scholastic • The features such as Did You Know?, Fast Forward, Top Tip, Update Office 2010, Tricky Terms, and Memory Bytes, enhance and reinforce conceptual knowledge.

4

1

Co-Scholastic • The features such as Computer Manners, Projects, and the design of the practical exercises focus both on scholastic and co-scholastic areas by creating awareness of the ethical and correct use of computers, as well as the use of computers as a tool for problem-solving in other subjects.
