This book is one of very few which, address in detail and in-depth, how preservice teachers build important mathematical ideas. A detailed case study of important mathematical learning by five preservice elementary school teachers, who construct powerful mathematical ideas by working through a major influential construction personally.

"Computer Power and Legal Language" explores the central issues involved in the use of computers to conduct legal business. The contributors, all experts in their field, take as their starting point fundamental questions about the potential utility of computational models of linguistics, intelligence, and logic in the law: Is it possible to use computing to communicate in the manner legal experts do? Can legal language be represented in computational form? How does natural language serve as both a bridge and a major stumbling block for the communication of concepts--both among jurists and computers? In answering these and other questions regarding computers in the law, the contributors present the results of research on the cutting edge of legal informatics, expert systems, and legal language, and they introduce important new applications of computers for lawyers.

Walter begins with an introductory chapter on the ways language is used in law. Subsequent chapters address a wide range of concerns: the relationship between precision in meaning and open texture in legal writing; the application of logic programming to law; a semantic representation of pre-contractual and contractual verbs of exchange; the use of CCLIPS, a computer program that reads and understands the Louisiana civil code; the interface between human users and legal information retrieval systems; and more. A state-of-the-art contribution to current research in the field, this book offers a much-needed synthesis of current theory and practice regarding computers and legal language.

"Weeds, Control Without Poisons" demonstrates the necessity in agriculture today for a more holistic, eco-centered perspective. The author explains what 50 years of deadly chemicals have already done to our soil and our bodies, demonstrating this process does not work in any long-term common sense agricultural system and offering alternatives to chemicals. Explores the workings of soil ecosystems and teaches how to understand and control the growth of countless weed species.

Ask the Plant, based on the agronomy of "K." Chandler, offers farmers and growers a better way to grow plants that involves reading the unique language of plants, utilizing leaf and petiole testing, and in turn knowing how to produce a better crop using only the fertilizers and soil-building ingredients that are truly needed, when they are most needed. Instead of following the decades old conventional model where plants are given copious amounts of soluble nitrogen fertilizers aimed to force-feed the landscape green, Ask the Plant addresses how to build a healthy soil without excessive inputs. After more than seven decades of soils being mined not replenished, especially of organic matter and minerals - it is time to "Ask the Plant" and find out what our crops and soils are really telling us so we can produce a better crop using only what is truly needed.

The soil is more than just a substrate that anchors crops in place. An ecologically balanced soil system is essential for maintaining healthy crops. 'Hands-On Agronomy' is a comprehensive manual on effective soil management. The function of micronutrients, earthworms, soil drainage, tilth, soil structure, and organic matter is explained in thorough detail. Kinsey demonstrates that working with the soil produces healthier crops with a higher yield. To that end, he provides an understanding of eco-agricultre as a viable enterprise that is both naturally and commercially sustainable. This work offers advice that is both highly valuable and applicable to the farmer of any level and promotes an ecological understanding of the farm from the ground up.
