Life Span Motor Development, Eighth Edition With HKPropel Access, is a leading text for helping students understand a person's movement abilities as the interaction of the individual's development and maturation, the environment, and the task being performed. This model of constraints approach, combined with an unprecedented collection of video clips marking motor development advancements, facilitates an unmatched learning experience for the study of motor development across the life span. Life Span Motor Development helps students understand how maturational age and chronological age are distinct and how functional constraints affect motor skill development and learning. It shows how the four components of physical fitness-cardiorespiratory endurance, strength, flexibility, and body composition-interact to affect a person's movements over the life span, and it describes how relevant social, cultural, psychosocial, and cognitive influences can affect a person's movements. It also now includes more content on atypical development; new Spotlight on Disability sidebars help readers use the constraints perspective to better understand how various disabilities influence motor development. The eighth edition continues the tradition of making the student's experience with motor development an interactive one. Related online learning tools delivered through HKPropel include an updated video library with more than 190 video clips, showing motor development milestones, to sharpen observation techniques; flash cards; key term quizzes; and lab activities to facilitate critical thinking and hands-on application. Some lab activities may be assigned and tracked by instructors through HKPropel, and sample answers for the lab activities are found in the instructor guide. Chapter quizzes are automatically graded to test comprehension of critical concepts. This edition features updated, modernized artwork and includes 146 illustrations, 60 photos, and 26 tables-all in full color-to help explain concepts and to make the text more engaging for students. It also retains helpful learning aids, including chapter objectives, a running glossary, key points, sidebars, and application questions throughout the text. Each chapter begins with a section titled Motor Development in the Real World, which presents realistic experiences that help readers connect with the material. Each chapter ends with a section titled Reinforcing What You Have Learned About Constraints, which prompts readers to answer questions about the material and complete learning exercises. Answers to these questions are included in the instructor guide. Life Span Motor Development, Eighth Edition, embraces an interactive and practical approach to illustrate the most recent research in motor development. Students will come away with a firm understanding of the concepts and how they apply to real-world situations. Note: A code for accessing HKPropel is included with all new print books.
