What is this field?" "Where have we come from as a discipline, and where are we going?" "What do I want to study?" These and other questions are typical for new students in the field of Learning and Instructional Design Technology. This textbook is designed to help answer these questions and provide the quickest route to understanding the history and current trends in the field. After surveying…
Nature provides us with many services seemingly for free: recharged groundwater, fertile soil and plant biomass created by photosynthesis. We human beings draw extensive benefits from these "ecosystem services," or ES -- food, water supply, recreation and protection from natural hazards. Major international studies, such as the Millennium Ecosystem Assessment, have addressed the enormous role o…
Early childhood is a critical time in development. Many outcomes, both positive and negative, have their beginnings in these years. It is vital that children’s health and safety be protected. High-quality early care and education programs can play a valuable role in improving outcomes for children.
According to Seels and Richey (1994), the educational technology field emerged, and continues to develop, through interactions of influences, including foundational research and theory and the features and capabilities of current technologies. This means the field of educational technology is “a child not only of theoretical knowledge, but also of practical knowledge” (p. 68). Theory from …
Readers will explore the foundations of American education through a critical lens. Topics include the teaching profession, influences on student learning, philosophical and historical foundations, structures of schools, ethical and legal issues, curriculum, classroom environment, and the path forward.
In the early twentieth century, scientists and theorists—such as Jean Piaget and Lev Vygotsky— developed widely studied theories to explain how young children acquire knowledge. Scientists have continued to study children’s ways of knowing by care- fully observing and listening as children pursue new skills, explore materials, solve problems, work together with others, and encounter e…
This book is a comprehensive, in-depth, and up-to-date resource on eye pathology that will be of great practical value for ophthalmic and general pathologists and ophthalmologists. Congenital abnormalities, inflammatory conditions, infections, injuries, degenerative diseases, and tumors are all covered with the aid of more than 700 images. In the case of tumors, the wide variety of neoplasms th…
This volume presents recent developments in the novel drug development and potential of extremophilic cyanobacteria. It discusses how these tiny organism originated, produce oxygen that leads to evolution of life on the earth, how their survival strategies in extreme climatic conditions lead to diverse metabolic pathways, and the opportunity to use them to develop novel drugs. The book is compr…
This book discusses the extremophiles explored for biosynthesis of nanoparticles. Nanotechnology is a widely emerging field involving interdisciplinary subjects such as biology, physics, chemistry and medicine. A wide variety of microorganisms, such as bacteria, fungi and algae are employed as biological agents for the synthesis of nanoparticles. Novel routes by which extremophiles can be emplo…
Extremophiles are known to thrive under harsh environmental conditions. Many extremophilic bio-products are already used as life-saving drugs. Recent technological advancements of systems biology have opened the door to explore these organisms anew as sources of products that might prove useful in clinical, environmental and drug development.
