What can bones tell us about past lives? Do different bone shapes, sizes, and injuries reveal more about people's genes or about their environments? Reading the Bones tackles this question, guiding readers through one of the most hotly debated topics in bioarchaeology. Elizabeth Weiss assembles evidence from anthropological work, medical and sports studies, occupational studies, genetic twin studies, and animal research. Examining the most commonly utilized activity pattern indicators in the field, she reevaluates the age-old question of genes versus environment. While cross-sectional geometries frequently inform on mobility, Weiss asks whether these measures may also be influenced by climate-driven body shape adaptions. Entheseal changes—at the locations of muscle attachments—and osteoarthritis indicate wear and tear on joints but are also among the best predictors of age and can be used to reconstruct activity patterns. Weiss also examines the most common stress fractures, such as spondylolysis and clay-shoveler's fracture; stress hernias or Schmorl's nodes; and activity indicator facets like Poirier's facets, Allen's facets, and Baastrup's kissing spines. Probing deeper into the complex factors that result in the varying anomalies of the human skeleton, this thorough survey of activity indicators in bones helps us understand which markers are mainly due to human biology and which are truly useful in reconstructing lifestyle patterns of the past.
"Efforts to improve mathematics teaching and learning globally have led to the ever-increasing interest in searching for alternative and effective instructional approaches from others. Students from East Asia, such as China and Japan, have consistently outperformed their counterparts in the West. Yet, Bianshi Teaching (teaching with variation) practice, which has been commonly used in practice in China, has been hardly shared in the mathematics education community internationally. This book is devoted to theorizing the Chinese mathematical teaching practice, Bianshi teaching, that has demonstrated its effectiveness over half a century; examining its systematic use in classroom instruction, textbooks, and teacher professional development in China; and showcasing of the adaptation of the variation pedagogy in selected education systems including Israel, Japan, Sweden and the US. This book has made significant contributions to not only developing the theories on teaching and learning mathematics through variation, but also providing pathways to putting the variation theory into action in an international context.“This book paints a richly detailed and elaborated picture of both teaching mathematics and learning to teach mathematics with variation. Teaching with variation and variation as a theory of learning are brought together to be theorized and exemplified through analysis of teaching in a wide variety of classrooms and targeting both the content and processes of mathematical thinking. Highly recommended.” – Kaye Stacey, Emeritus Professor of Mathematics Education, University of Melbourne, Australia “Many teachers in England are excited by the concept of teaching with variation and devising variation exercises to support their pupils’ mastery of mathematics. However, fully understanding and becoming proficient in its use takes time. This book provides a valuable resource to deepen understanding through the experiences of other teachers shared within the book and the insightful reflections of those who have researched this important area. – Debbie Morgan, Director for Primary Mathematics, National Centre for Excellence in the Teaching of Mathematics, United Kingdom"
