It begins in Babylon, then describes the trials and tribulations of the Greek mathematicians. The important, and often neglected, influence of both Chinese and Islamic mathematics is covered in detail, placing the description of early Western mathematics in a global context. The book concludes with modern mathematics, covering recent developments such as the advent of the computer, chaos theory, topology, mathematical physics, and the solution of Fermat's Last Theorem. Containing more than 100 illustrations and figures, this text, aimed at advanced undergraduates and postgraduates, addresses the methods and challenges associated with studying the history of mathematics. The reader is introduced to the leading figures in the history of mathematics (including Archimedes, Ptolemy, Qin Jiushao, al-Kashi, al-Khwarizmi, Galileo, Newton, Leibniz, Helmholtz, Hilbert, Alan Turing, and Andrew Wiles) and their fields. An extensive bibliography with cross-references to key texts will provide invaluable resource to students and exercises (with solutions) will stretch the more advanced reader. |

| exterior angles of triangles answer key with work: Teaching Mathematics in Grades 6 - 12 Randall E. Groth, 2012-08-10 Teaching Mathematics in Grades 6 - 12 by Randall E. Groth explores how research in mathematics education can inform teaching practice in grades 6-12. The author shows preservice mathematics teachers the value of being a researcher—constantly experimenting with methods for developing students' mathematical thinking—and connecting this research to practices that enhance students' understanding of the material. Ultimately, preservice teachers will gain a deeper understanding of the types of mathematical knowledge students bring to school, and how students' thinking may develop in response to different teaching strategies. |

| exterior angles of triangles answer key with work: Seven Myths About Education Daisy Christodoulou, 2014-03-14 In this controversial new book, Daisy Christodoulou offers a thought-provoking critique of educational orthodoxy. Drawing on her recent experience of teaching in challenging schools, she shows through a wide range of examples and case studies just how much classroom practice contradicts basic scientific principles. She examines seven widely-held beliefs which are holding back pupils and teachers: Facts prevent understanding Teacher-led instruction is passive The 21st century fundamentally changes everything You can always just look it up We should teach transferable skills Projects and activities are the best way to learn Teaching knowledge is indoctrination In each accessible and engaging chapter, Christodoulou sets out the theory of each myth, considers its practical implications and shows the worrying prevalence of such practice. Then, she explains exactly why it is a myth, with reference to the principles of modern cognitive science. She builds a powerful case explaining how governments and educational organisations around the world have let down teachers and pupils by promoting and even mandating evidence-less theory and bad practice. This blisteringly incisive and urgent text is essential reading for all teachers, teacher training students, policy makers, head teachers, researchers and academics around the world. |
