This book examines the relationship between generative artificial intelligence (AI) technologies, like ChatGPT, and their potential to transform the educational landscape. It starts with acknowledging the rapid integration of AI across various fields, particularly education, highlighting the urgent need to address ethical issues such as data privacy, bias, transparency, and intellectual property rights. Spanning several sections, the book provides a thorough overview of AI's core principles, its expanding role in education, the ethical dilemmas it raises, and strategies for its ethical use. Central to this guide is the urgent call for creating and implementing an ethical framework to address the complex challenges and opportunities AI presents in education. It aims to arm educators, policymakers, and AI developers with the necessary insights and tools to advocate for a balanced approach that places a premium on student welfare and equal access to learning resources. The introduction lays the foundation for a detailed discussion on the responsible and ethical application of generative AI in education, setting the stage for an extensive review of AI's basic principles, ethical considerations, pedagogical implications, and approaches to inclusivity. Starting with foundations of AI in education, the book delves into generative AI's theoretical basis and historical development within the educational sphere, charting its journey from the inception of computer-assisted learning to today's advanced language models. Moving on to ethical and responsible use, the discussion broadens to address the ethical challenges associated with employing generative AI in education, advocating for a balance between innovation and ethical considerations to promote a culture of responsible lifelong learning. In pedagogical implementation, the focus shifts to the practical aspects of integrating AI into curricula, highlighting pedagogical strategies that reflect best practices and examining the impact of language models on lifelong learning.
