Big Ideas Foundational Material Compelling and Second Order Applications Generic Computer Tools ICT as Curriculum Content ICT in Assessment and Accountability Summary and Recommendations Moursund Preface "Without a struggle, there can be no progress. This book is designed for use by PreK preservice and inservice teachers, and by teachers of these teachers.
It provides a brief overview of some of the key topics in the field of Information and Communication Technology ICT in education. I wrote this book to help serve the needs of my students in a course titled Teaching and Learning in the Digital Age. The mission of this book is to help improve the education of PreK students. A three- pronged, research-based approach is used.
Goal 1 of this book is to help you increase your expertise as a teacher. Goal 2 of this book is to help increase your knowledge and understanding of various roles of ICT in curriculum content, instruction, and assessment.
There is significant research to support the benefits of ICT in these three areas. In addition, ICT is now an important content area in each of the disciplines that you teach or are preparing to teach. Goal 3 of this book is to help you increase your higher-order, critical thinking, problem-solving knowledge and skills.
Special attention is paid to roles of ICT as an aid to solving complex problems and accomplishing complex tasks in all curriculum areas. Research suggests that US schools are not nearly as strong as they could be in helping students gain increased expertise in problem solving and critical thinking. Now that I have stated goals for this book, I want to make clear a non-goal. This book is not designed to help you learn specific pieces of software.
The typical first ICT in Education course for preservice and inservice teachers has a strong focus on learning to make use of various pieces of hardware, software, and connectivity. This book is not designed as a substitute for, or a major aid to, learning these rudiments of ICT that are now being learned by many students before they get to college.
This book is designed to addresses some of the weaknesses of typical first or second ICT in education courses that overemphasize learning computer applications and underemphasize other aspects of the field of ICT in education. The emphasis is on higher-order knowledge and skills. Moursund book we argue that basic skills lower-order knowledge and skills, rudimentary use of some of the general purpose pieces of computer software should be integrated in with higher-order knowledge and skills.
The prerequisite for a course using this book is an introductory level of knowledge and skill in using a word processor in a desktop publication environment, using email, and using the Web. Nowadays, large numbers of students meet this prerequisite by the end of the 5th grade, since such knowledge and skills are only part of the 5th grade standards for students established by the International Society for Technology in Education ISTE NETS n.
Increasingly, instruction in such basic skills is not considered to be an appropriate part of a college-level curriculum that carries credit towards a college degree. As you read this book, you will come to understand that ICT in education is a broad, deep, and rapidly growing field of study.
ICT has the potential to contribute to substantial improvements in our educational system. To date, relatively little of this potential has been achieved. Moreover, the pace of change of the ICT field currently exceeds the pace of progress in making effective use of ICT in education. Thus, the gap between the potentials and the current uses of ICT to improve PreK education is growing. ICT is a very rapidly changing field.
This book will provide you with some answers. Moursund Chapter 0 Big Ideas "Mankind owes to the child the best it has to give. Relatively few people thoroughly read an entire textbook. Their enthusiasm, interest, and energy level tends to wane as the book drags on and on. To address this problem, I have done two things. First, I have kept this book relatively short. Second, I have placed a large chunk of my intended last chapter at the beginning.
Since it comes before the ordinary first chapter, I have numbered it Chapter 0. Chapter 0 contains a brief introduction to and summary of the Big Ideas the unifying, very important themes covered in this book.
I hope that your reading of this chapter will lead you into reading subsequent chapters. When and if you reach the end of this book, please come back and read Chapter 0 again. You may be pleasantly surprised by how much you have learned! It includes the full range of computer hardware and software, telecommunication and cell phones, the Internet and Web, wired and wireless networks, digital still and video cameras, robotics, and so on. It includes the field of Computer and Information Science and a huge and rapidly growing knowledge base that is being developed by practitioners and researchers.
ICT has proven to be a valuable aid to solving problems and accomplishing tasks in business, industry, government, education, and many other human endeavors. This remainder of this chapter lists a few of the Big Ideas the important, long-lasting, unifying ideas that have guided the development of the material in this book.
The idea is that properly educated people, using tools that aid their physical bodies and their minds, can solve a wide variety of challenging problems and accomplish a wide variety of challenging tasks. Moursund Tools to extend Tools to extend physical mental capabilities. Problem-Solving, Task-Accomplishing Team Formal and informal education and training to build mental and physical capabilities and one! Figure 0. Problem-solving, task-accomplishing team.
The center of the diagram is a person or group of people working to solve a problem or accomplish a task. The top part of the diagram focuses on the idea that throughout human history, humans have been developing tools to enhance the capabilities and performance of their bodies and minds. Reading, writing, and arithmetic were developed as an aid to solving the problems and accomplishing the tasks of a thriving and growing agricultural society.
Reading, writing, and arithmetic were the first tools that required a formal and protracted education system. Up to that time, the body and mind tools could be learned through informal education and apprentice systems. The past 5, years have seen a huge growth in the number of students receiving formal education and the length of that formal education. Also during the past 5, years, many new body and mind tools have been developed, and many of these have been widely adopted.
In terms of the diagram of Figure 0. A library can be thought of as being a mind tool. It facilitates the single most important aspect of problem solving—building on the previous work of others Moursund, a. The Web is a global library that is steadily growing in the depth and breadth of its contents. Communication over distance and time is an essential component of building on the work of other people.
Thus, the Internet which includes the Web is of steadily growing importance in education. Automated factory tools are, or course, an obvious example of this progress. The combination of paper, pencil, and such algorithms is a powerful aid to the human mind in representing and solving arithmetic computational problems. ICT now plays a major role in factory automation. Such uses of ICT raise a critical educational issue: If an ICT system can solve a type of problem or accomplish a type of task that we currently teach students in school to do without use of ICT, what should we now be teaching students about this problem or task?
Big Idea 2: ICT is a Change Agent The invention or development of a new physical body or mental tool creates both opportunities and challenges.
In brief summary, a new tool typically: 1. Helps us to solve some problems and accomplish some tasks that cannot be solved without the new tool. Creates new problems. This problem preceded the digital divide problem by about 5, years. ICT is an example of a technology that is a powerful change agent.
Going back to Figure 0. We now have microscopes, telescopes, brain scanning equipment, automated factories, and a huge range of other tools that are highly dependent on ICT. We can also view ICT as a mind tool.
It is evident that ICT incorporates and extends some of the power of reading, writing, and arithmetic.
For example, the Internet facilitates global communication and the Web a global library. ICT facilitates the automation of many mental activities.
Module 1 – Basic concepts of Information and Communication Technology (ICT) – notes
Information and communications technology ICT is an extensional term for information technology IT that stresses the role of unified communications  and the integration of telecommunications telephone lines and wireless signals and computers, as well as necessary enterprise software , middleware , storage and audiovisual, that enable users to access, store, transmit, and manipulate information. The term ICT is also used to refer to the convergence of audiovisual and telephone networks with computer networks through a single cabling or link system. There are large economic incentives to merge the telephone network with the computer network system using a single unified system of cabling, signal distribution, and management. ICT is an umbrella term that includes any communication device, encompassing radio, television, cell phones, computer and network hardware, satellite systems and so on, as well as the various services and appliances with them such as video conferencing and distance learning. ICT is a broad subject and the concepts are evolving.
The journal aims to provide a forum for publication and dissemination of scientific research conducted in the fields of management, as well as promote the interconnection of academic research with practical reality. It is intended to disseminate the scientific results obtained by academics and professionals, both nationally or internationally. The journal is based on a process of double blind review. Information communication technology ICT mediated innovation—adoption—implementation is one of the prime factors in the development of a nation. Its enhancement can improve the productive capacity of developing countries. Though developing countries import much of their technology from abroad, ultimate success depends on the technological efforts and capabilities of individuals and organizations.

Сэр… видите ли, он у. - Что значит у вас? - крикнул директор. Это могло оказаться лучшей новостью за весь день. Смит потянулся к объективу камеры, чтобы направить его в глубь кузова. На экране промелькнула внутренняя часть мини-автобуса, и перед глазами присутствующих предстали два безжизненных тела у задней двери.
Она вдруг начала светиться под кончиком пальца. Электричество. Окрыленная надеждой, Сьюзан нажала на кнопку.
Боже мой! - Она улыбнулась. - Вы, американцы, совсем не умеете торговаться. На нашем рынке вы бы и дня не продержались.
Никаких ограничений - только свободная информация. Это шанс всей вашей жизни. И вы хотите его упустить.
Да, сэр. У нас все это записано на пленку, и если вы хотите… - Исчезает фильтр Х-одиннадцать! - послышался возглас техника. - Червь преодолел уже половину пути. - Забудьте про пленку, - сказал Бринкерхофф.
Я сказала. - Я знаю.
В ответ - тишина. Его руки крепче сжали ее шею. - Я сейчас ее убью. Сзади щелкнул взведенный курок беретты. - Отпусти ее, - раздался ровный, холодный голос Стратмора.
Коммандер. Нужно выключить ТРАНСТЕКСТ. У нас… - Он нас сделал, - сказал Стратмор, не поднимая головы. - Танкадо обманул всех. По его тону ей стало ясно, что он все понял.
Вторично разоблачив попытку АНБ пристроить к алгоритму черный ход, Грег Хейл превратится в мировую знаменитость. И одновременно пустит АНБ ко дну. Сьюзан внезапно подумала, что Хейл, возможно, говорит правду, но потом прогнала эту мысль. Нет, решила .
Поэтому я и узнал о его намерении модифицировать Цифровую крепость. Я читал все его мозговые штурмы.
