How does a scientist go about solving problems? How do scientific discoveries happen? Why are cold fusion and parapsychology different from mainstream science? What is a scientific worldview? In this lively and wide-ranging book, Gregory Derry talks about these and other questions as he introduces the reader to the process of scientific thinking. From the discovery of X rays and semiconductors to the argument for continental drift to the invention of the smallpox vaccine, scientific work has proceeded through honest observation, critical reasoning, and sometimes just plain luck. Derry starts out with historical examples, leading readers through the events, experiments, blind alleys, and thoughts of scientists in the midst of discovery and invention. Readers at all levels will come away with an enriched appreciation of how science operates and how it connects with our daily lives.

There are many reasons why you might need to learn a foreign language quickly. The author, a U.S. Army Green Beret, often travels to foreign countries on short notice and needs to be able to communicate with military and government officials, many of who do not speak English. He tried all types of schools, classes, books and tapes, but none delivered what he needed when he needed it. So he developed his own method for learning foreign languages. It proved so effective for him and his fellow Green Berets that he decided to share his method with others who need to learn a language quickly. The Quick and Dirty Guide to Learning Languages Fast is designed for people who have no interest in learning complicated rules of grammar.

Dynamic Assessment (DA) reconceptualizes classroom interactions by arguing that teaching and assessment should not be distinct undertakings but must be integrated as a single activity that seeks to understand learner abilities by actively supporting their ongoing development. DA is based in the Vygotskian notion of the Zone of Proximal Development (ZPD) which captures the uniquely human potential to exceed our present capabilities by working in cooperation with others whose dialogic interaction mediates us to higher levels of functioning. DA offers a framework for co-constructing a ZPD with learners in order to simultaneously reveal the full range of their abilities and promote development.

This book presents the first in-depth analysis of DA’s application to particular problems of L2 development. It includes detailed discussions of the core theoretical tenets as well as guidelines for implementing DA principles in L2 classrooms. The book will be of interest to language teacher educators, language testers, classroom practitioners, and students and researchers in the areas of SLA, language pedagogy, and assessment.
