A Focus on Ratios and Proportions

A Focus on Ratios and Proportions PDF Author: Marjorie M. Petit
Publisher: Routledge
ISBN: 1000071448
Category : Education
Languages : en
Pages : 264

Book Description
This resource offers a groundbreaking effort to make mathematics education research on ratios and proportions readily accessible and understandable to preservice and in-service teachers of grades 6 to 8. Using extensive annotated samples of student work and based on research gathered in the Ongoing Assessment Project (OGAP), A Focus on Ratios and Proportions teaches readers how students develop understanding and fluency involving ratio and proportion concepts. Special features include: A close focus on student work, including 150+ annotated pieces of student work, to help teachers improve their ability to recognize, assess and monitor their students’ errors and misconceptions, as well as their developing conceptual understanding. A focus on the OGAP Ratios and Proportions Progression, based on research conducted with hundreds of teachers and thousands of pieces of student work. Sections on how Common Core State Standards for Math (CCSSM) are supported by math education research. Student work samples and vignettes to illuminate the research, as well as end of chapter Looking Back questions and Instructional Links, which allow teachers to analyze evidence of student thinking and strategies and consider instructional responses. An accompanying eResource, available online, offers an answer key as well as extensive explanation of the Looking Back questions. Like A Focus on Multiplication and Division and A Focus on Fractions, this book is designed to bridge the gap between what math education researchers know and what teachers need to know in order to better understand evidence in student work and make effective instructional decisions.

A Study of Flutter at Low Mass Ratios with Possible Application to Hydrofoils

A Study of Flutter at Low Mass Ratios with Possible Application to Hydrofoils PDF Author: Robert W. Herr
Publisher:
ISBN:
Category :
Languages : en
Pages : 32

Book Description
Experimental flutter-test results for some flexible cantilever-wing models partly submerged in water are presented. The results tend to corroborate theoretical predictions of a stable region at low ratios of structural mass to fluid mass. Theoretical studies indicate this dynamic stability to be closely associated with the presence of fluid damping forces. An explicit expression is presented which defines the lowest mass ratios for which representative section (flexure-torsion) flutter solutions are obtainable as a function of the various structural parameters. Classical flutter of hydrofoils is possible, especially for heavy sections with the center of gravity located far aft. Theoretical indications are that the flutter boundary at low mass ratios is very sensitive to small differences in the various theories. Inclusion of sweep in a modal analysis resulted in flutter solutions in the low mass-ratio range where none had previously been obtained. (Author).

Research Methodology in Strategy and Management

Research Methodology in Strategy and Management PDF Author: David J. Ketchen
Publisher: Elsevier
ISBN: 0762310510
Category : Business & Economics
Languages : en
Pages : 375

Book Description
Research methods present the strategic management field with great opportunities and challenges. This first volume includes three types of chapters aimed at exploiting the opportunities and meeting the challenges. One group of chapters addresses broad issues of science, including the state of strategy research, issues surrounding the age of data, and how to build cumulative knowledge within the strategic management field. A second group of chapters highlight ways to improve specific practices, including the measurement of knowledge, the assessment of limited dependent variables, and designing studies. A final group of chapters describe how strategy researchers can better use particular methods. These methods include social network analysis, longitudinal analysis, qualitative methods, survey research, and structural equation modeling. Collectively, the chapters offer state of the art thinking about research methodology provided by intellectual leaders within the strategic management field.

Teaching Fractions and Ratios for Understanding

Teaching Fractions and Ratios for Understanding PDF Author: Susan J. Lamon
Publisher: Routledge
ISBN: 1135606781
Category : Education
Languages : en
Pages : 254

Book Description
This popular text addresses the urgent need for curriculum materials that cross traditional boundaries to include many of the elements that are integrated in the teaching/learning enterprise: mathematics content, teacher understanding, student thinking, teaching methods, instructional activities, and assessment. The book pushes readers beyond the limits of their current understanding of rational numbers, challenging them to refine and explain their thinking--without falling back on rules and procedures they have relied on throughout their lives. Written in a conversational and easy to understand style, this is not a textbook as much as it is a resource book. An underlying assumption is that facilitating teacher understanding using the same questions and activities that may be used with children is one way to help teachers build the comfort and confidence they need to begin talking to children about complex ideas. Unlike a textbook that is used to study formal theory and then discarded when it comes to putting ideas into practice, the many problems and activities included to facilitate teacher learning are valuable resources for use in elementary and middle school classrooms. Changes in the second edition include: *even more student work incorporated in every chapter; *discussion of the connectivity between the topics addressed in the book and the elementary and middle school mathematics curricula; *an increased emphasis on measurement; *expansion of some topics, including number sense, percent, scale factors, similarity, and linear graphs; *clarification of the characteristics of ratio and proportions and how to use these to generate discussion with children; and *content-related interview questions for exploring children's thinking. This book is a valuable resource for researchers and curriculum developers in mathematics education, pre-service and in-service teachers of mathematics, those involved in the mathematical and pedagogical preparation of mathematics teachers, and graduate students in mathematics education. The methods and activities it includes have been tested with students in grades 3-8 and with pre-service and in-service teachers and other adults. This text is accompanied by MORE--a supplement that is not merely an answer key but a resource that includes in-depth discussions of all the problems in the text; develops and extends discussion of the issues, teaching problems, and other considerations raised in the chapters; and contains additional problems--with and without solutions--that instructors may find helpful for assessment purposes.
