Book Description
Computer technology, large number of people and dependence on Al has led to large transactions of data throughout the world. The need to study data science has never been greater. Various types of data have to be interacted with and various technical methods are used to open files received in these transactions. Data Science is itself very much grounded on Mathematics and Statistics, and cannot be understood without relying a lot on computer science. With these points in mind, the CBSE has suggested that the subject Data Science be added as a subject in Classes 11 and 12. We have come out with this book, "A Textbook of Data Science for class 11." The book is divided into two parts: Parts A (Employability Skills) and B (Subject Specific Skills). • Part A consists of the chapters on Communication Skills - Ill, Self Management Skills - Ill, ICT Skills - Ill, Entrepreneurial Skills - Ill and Green Skills - Ill. • Part B consists of data science related chapters. They are Ethics in Data Science, Assessing Data, Forecasting on Data, Randomization and Introduction to R Studio. The chapters have the following features: •:• Learning Objectives: It describes the goals to be achieved by the end of the chapter. •:• Chapter Contents: Concepts are explained to strengthen the knowledge base of the learners. •:• Check Your Knowledge: It gives question(s) to test the student's understanding of the chapter taught. •:• Test Yourself: It includes questions with headings such as Multiple choice questions, Match the following, Short Answer Type questions, Long answer type questions, Activity Zone and Group Discussion. This effort of ours will be of immense use for the students and teachers. Any feedback given regarding the quality of the material will be gracefully accepted and acknowledged. We intend to improve the book further, if possible. AUTHOR

Book Description
The term "artificial intelligence" may sound intimidating to some, but it has been in use for decades and its applications are more common than you might imagine. It is gaining the spotlight across applications in our personal and professional lives. AI is still at a relatively early stage of development, so that the range of potential applications, have ample scope left for further development. It holds the promise of solving some of the most pressing issues facing society, but also presents challenges such as unethical use of data and potential job displacement. There are so many amazing ways artificial intelligence and machine learning are used behind the scenes to impact our everyday lives. A1 assists in every area of our lives, whether we're trying to read our emails, get driving directions, get music or movie recommendations. AI is a constellation of technologies that enable machines to act with higher levels of intelligence and emulate the human capabilities of sense, comprehend and act. A1 is not specifically related to computer science. This is a field of study that encompasses human behaviour, biology, psychology, and even language and linguistics. AI presents opportunities to complement and supplement human intelligence and enrich the way people live and work. Artificial Intelligence is being widely recognized to be the power that will fuel this future global digital economy. Countries around the world are becoming increasingly aware of the potential benefits of developing and applying AI. From SIRI to self-driving cars, artificial intelligence (AI) is progressing rapidly. While science fiction often portrays AI as robots with human-like characteristics, AI can encompass anything from Google's search algorithms to IBM's Watson to autonomous weapons. From Amazon shopping recommendations, Facebook image recognition, and personal assistants like Siri, Cortana, and Alexa, your phone is becoming a portal to real-world applications of artificial intelligence. This book is a "glimpse into the future" that illustrates how AI will continue to transform our daily lives in the near future. Digitalisation and the new technological possibilities that artificial intelligence (A1) brings are driving the biggest social and economic changes since the industrial revolution. Without the right political, economic and ethical framework conditions there is a risk of uncontrolled development and a negative impact of AI. Artificial intelligence (A1) is doing a lot of good and will continue to provide many benefits for our modern world, but along with the good, there will inevitably be negative consequences. The sooner we begin to contemplate what those might be, the better equipped we will be to mitigate and manage the dangers. While writing the book, we have tried to keep the explanation simple with lots of examples and illustrations. Lastly, there is always a scope of improvement. Thus, it is a request to our esteemed readers to send the feedback and suggestions etc for the improvement of the book. All your requests are welcome.

Approaches to Qualitative Research in Mathematics Education
Author: Angelika Bikner-Ahsbahs
Publisher: Springer
ISBN: 9401791813
Category : Education
Languages : en
Pages : 587
Book Description
This volume documents a range of qualitative research approaches emerged within mathematics education over the last three decades, whilst at the same time revealing their underlying methodologies. Continuing the discussion as begun in the two 2003 ZDM issues dedicated to qualitative empirical methods, this book presents astate of the art overview on qualitative research in mathematics education and beyond. The structure of the book allows the reader to use it as an actual guide for the selection of an appropriate methodology, on a basis of both theoretical depth and practical implications. The methods and examples illustrate how different methodologies come to life when applied to a specific question in a specific context. Many of the methodologies described are also applicable outside mathematics education, but the examples provided are chosen so as to situate the approach in a mathematical context.

One message of Peace Process is that the United States has had, and will continue to have, a crucial role in helping Israel and her Arab neighbors reach peace. If American presidents play their role with skill, they can make a lasting contribution. But just as likely, they may misread the realities of the Middle East and add to the impasse by their own errors.
