This book is designed to help teachers at school and colleges to ask the right questions and provide the right answers. It is based on the teaching and research activities of the Mathematics Education Group at Brunel University. The research studies with some 22,000 learners aged from 10 to 57 years have shown that there are certain basic mathematical tasks which cause common misconceptions: what is learnt today does indeed matter tomorrow. Diagnosis of these misconceptions is, however, subtle; in tasks which look similar, only certain kinds really probe the learner′s understanding. An introductory chapter discusses the need for, and the art of, diagnosis. The central theme of diagnosis allied to prescriptions is then discu

Have you ever wondered why we put salt on icy sidewalks, or what makes grass turn yellow and why some things seem to "talk back" to you? Through personal investigation, youngsters can find answers to these and more than 30 other intriguing questions in this stimulating book by a former science consultant to the New York City Board of Education. By following simple instructions, children at the elementary school level can easily perform these experiments at home or in the classroom. Each project is clearly outlined, and carefully drawn illustrations indicate what materials are needed and how to set up equipment. (Parents will be happy to know that materials suggested for these research projects are safe, inexpensive and easily available.) By working with such common household items as a potato and a drinking straw, for example, researchers can learn how a tornado is able to drive a blade of dried grass into a tree trunk. Other challenging problems include designing an electric meter, burglar-proofing a school bag, producing animal sounds by vibration, preparing a timetable for nature, making an unusual window garden and learning where carbon dioxide can be found in the home. This book is ideal for the child who enjoys discovering answers to original experiments and solving scientifically intriguing problems. Even more important, each of these projects may spur the eager investigator on to further explorations in the thrilling field of scientific research.

Does a curve ball really curve? Why is a football made to spiral when it's thrown? How is the bounce of a basketball tested before a game? These and hundreds of other questions are answered in this fascinating book—an easy-to-follow examination of the scientific principles underlying baseball, football, basketball and other sports. In clear, simple language, noted science educator George Barr presents physical concepts that can help youngsters improve their athletic skillswhile making them more knowledgeable spectators of sports. Inerita vs. motion, gravity, speed, trajectory, and action vs. reaction are among the topics covered in Mr. Barr's well-illustrated presentation. Here are intriguing descriptions of what happens when baseballs are pitched and batted, and the physical processes involved in catching, fielding and running bases. You'll discover how the principles of momentum come into play in football, while a discussion of basketball provides scientific insights on the movement of the ball around the court in a high-speed game. A special chapter on the athlete's body describes how certain principles of physics can affect a player's ability to perform, and how youngsters can improve their performance by letting science work for them instead of against them. While most of the book is devoted to baseball, football and basketball, the author has also included a delightful chapter on other sports. Here are the answers to such puzzling questions as: What helps riders keep their balance on a bike? Why do golf balls have dimples? and more. Sure to appeal to any athletically minded youngster with an interest in the science behind the sports, this book is one "no school library shelf whould be without" (New York Herald Tribune).

This simply written introduction to scientific research and experimentation takes youngsters into an exciting world where they'll not only learn to discover their own answers to specific problems but will be encouraged to develop sound scientific attitudes and techniques as well. For this volume, noted science educator George Barr has compiled a carefully selected array of intriguing experiments dealing with chemistry, astronomy, magnetism and electricity, weather, water, the human body, living things, sound and light, and measurement. By performing these experiments, young researchers will discover the answers to such questions as "Why Can't We See Stars in the Daytime?" "How Can a Spider Web be Collected?" "Can Water Containing Ice Get Warm?" "How Can We See Sound Vibrations?" "What Helps Your Memory?" and many others. As the author early points out, the work is "not a reading book, but rather a doing book" with a chapter containing suggestions for further experiments. Valuable advice about scientific procedures emphasize the importance of taking readable, organized notes; gathering as much evidence as possible; learning to use "control" groups; and much more. In addition, over 100 illustrations enhance the text, which also contains a selected bibliography of relevant reading material.

"Scale" is well known and understood in creative arts such as architecture, sculpture and music, but New Testament scholars have given no significant consideration to scale changes in the Biblical texts.A robust methodology allows scale changes in literature to be examined scientifically and reveals "scale-related" patterns in the epistles. To determine the significance of these patterns, George Barr has conducted a wide survey covering many texts in Greek, Latin and English. It reveals that the patterns found in the New Testament are very rare indeed, if not unique, and gives grounds for the belief that such patterns are associated with authorship.The patterns found in the Pauline epistles clarify some theories regarding the origins of the epistles and, in some cases, shed new light on their compilation.
