Book Description
Anyone who has ever run a small business knows how it feels to wear many hats—CEO, Designer, Marketer, Accountant, Lawyer, and more. Swiftly changing multiple hats as you work, you end the day running on fumes, wondering if you really did anything well. You wish you could hire a team that could take some things off your plate, but you are still bootstrapping and don't yet have the financial resources to employ others to do some of the things you currently do. But what if you could build a Team of Robots and deploy them to work full-time with you? They won't get tired like you and I, they won't take vacations, they won't call in sick, nor would they experience other limitations that are common with us. The truth is this, there are several tools out there to help you build such. A Team of Robots is a simple guide to introduce you to various automation possibilities you can explore using available AI tools and platforms to make your work easier and more effective. With its simple step-by-step micro-projects, this book lays a foundation on which you can build and explore more areas of application in using available AI tools and platforms to expand your Team of Robots.

ISBN: 1681230526
Category : Education
Languages : en
Pages : 262
Book Description
A Book for Every Teacher: Teaching English Language Learners is a unique and compressive text written for mainstream classroom teachers. The passion for writing this book comes from our working experiences with the K–12 teachers in four school districts through our ELL Center professional development program. Through this program, we provide professional training through our federally funded research and service projects. The purpose of our professional training is to prepare general education teachers to work effectively with English language learners (ELLs). While working with the teachers on a daily basis, we know the immediate needs of the teachers. This motivated us to embark this book project. In recent years, the ELL school population has the highest increase among school populations. As the NEA data indicates, providing ELL students with high quality services and programs is an important investment in America’s future (NEA, 2013). This book is our investment in helping teachers to meet their challenges and provide useful information and strategies for teaching ELLs. The book is designed with K–12 teachers in mind. It is best used by teachers who have or will have ELLs in their classrooms and who seek information and strategies to better work with and serve their ELLs to achieve academic success. With this design, teachers can use the book as a text or reference tool. This book can also be adopted as text materials for professional training. Teachers are the most important factor for ELLs’ academic success.
