Download or read book Do secrets come out Statistical evaluation of student cheating written by Anatoly Peresetsky and published by Litres. This book was released on 2022-01-29 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: We suggest an original method of student cheating evaluation based on the comparison of students’ grades in exams in class, home assignments and experimental homework. The data for the study is collected from the survey of 2012–2013 sophomores of the International College of Economics and Finance at the National Research University Higher School of Economics in Moscow, Russia. At the end of the course in Statistics in addition to standard assignments (homework and exams) students were given experimental homework with a ban on cooperation among them. The violation of this rule was qualified as cheating. The scale of cooperation is measured and then tested through the stochastic frontier technique; it reveals connection with the GPA level, students’ expectations of the cheaters’ share and students’ moral norms. We also find different behavioral patterns for high and low performing students as well as country specific context of student cheating behavior.
Download or read book Measuring Up written by Daniel Koretz and published by Harvard University Press. This book was released on 2009-09-15 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do you judge the quality of a school, a district, a teacher, a student? By the test scores, of course. Yet for all the talk, what educational tests can and can’t tell you, and how scores can be misunderstood and misused, remains a mystery to most. The complexities of testing are routinely ignored, either because they are unrecognized, or because they may be—well, complicated. Inspired by a popular Harvard course for students without an extensive mathematics background, Measuring Up demystifies educational testing—from MCAS to SAT to WAIS, with all the alphabet soup in between. Bringing statistical terms down to earth, Daniel Koretz takes readers through the most fundamental issues that arise in educational testing and shows how they apply to some of the most controversial issues in education today, from high-stakes testing to special education. He walks readers through everyday examples to show what tests do well, what their limits are, how easily tests and scores can be oversold or misunderstood, and how they can be used sensibly to help discover how much kids have learned.
Download or read book The Overachievers written by Alexandra Robbins and published by Hachette Books. This book was released on 2006-08-08 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bestselling author of Pledged returns with a groundbreaking look at the pressure to achieve faced by America's teens In Pledged, Alexandra Robbins followed four college girls to produce a riveting narrative that read like fiction. Now, in The Overachievers, Robbins uses the same captivating style to explore how our high-stakes educational culture has spiraled out of control. During the year of her ten-year reunion, Robbins goes back to her high school, where she follows heart-tuggingly likeable students including "AP" Frank, who grapples with horrifying parental pressure to succeed; Audrey, whose panicked perfectionism overshadows her life; Sam, who worries his years of overachieving will be wasted if he doesn't attend a name-brand college; Taylor, whose ambition threatens her popular girl status; and The Stealth Overachiever, a mystery junior who flies under the radar. Robbins tackles teen issues such as intense stress, the student and teacher cheating epidemic, sports rage, parental guilt, the black market for study drugs, and a college admissions process so cutthroat that students are driven to suicide and depression because of a B. With a compelling mix of fast-paced narrative and fascinating investigative journalism, The Overachievers aims both to calm the admissions frenzy and to expose its escalating dangers.

Available in PDF, EPUB and Kindle. Book excerpt: Statistical Rethinking: A Bayesian Course with Examples in R and Stan builds readers’ knowledge of and confidence in statistical modeling. Reflecting the need for even minor programming in today’s model-based statistics, the book pushes readers to perform step-by-step calculations that are usually automated. This unique computational approach ensures that readers understand enough of the details to make reasonable choices and interpretations in their own modeling work. The text presents generalized linear multilevel models from a Bayesian perspective, relying on a simple logical interpretation of Bayesian probability and maximum entropy. It covers from the basics of regression to multilevel models. The author also discusses measurement error, missing data, and Gaussian process models for spatial and network autocorrelation. By using complete R code examples throughout, this book provides a practical foundation for performing statistical inference. Designed for both PhD students and seasoned professionals in the natural and social sciences, it prepares them for more advanced or specialized statistical modeling. Web Resource The book is accompanied by an R package (rethinking) that is available on the author’s website and GitHub. The two core functions (map and map2stan) of this package allow a variety of statistical models to be constructed from standard model formulas.

Download or read book Defending Assessment Security in a Digital World written by Phillip Dawson and published by Routledge. This book was released on 2020-10-26 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Defending Assessment Security in a Digital World explores the phenomenon of e-cheating and identifies ways to bolster assessment to ensure that it is secured against threats posed by technology. Taking a multi-disciplinary approach, the book develops the concept of assessment security through research from cybersecurity, game studies, artificial intelligence and surveillance studies. Throughout, there is a rigorous examination of the ways people cheat in different contexts, and the effectiveness of different approaches at stopping cheating. This evidence informs the development of standards and metrics for assessment security, and ways that assessment design can help address e-cheating. Its new concept of assessment security both complements and challenges traditional notions of academic integrity. By focusing on proactive, principles-based approaches, the book equips educators, technologists and policymakers to address both current e-cheating as well as future threats.

Download or read book Causal Inference written by Scott Cunningham and published by Yale University Press. This book was released on 2021-01-26 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: An accessible, contemporary introduction to the methods for determining cause and effect in the Social Sciences “Causation versus correlation has been the basis of arguments—economic and otherwise—since the beginning of time. Causal Inference: The Mixtape uses legit real-world examples that I found genuinely thought-provoking. It’s rare that a book prompts readers to expand their outlook; this one did for me.”—Marvin Young (Young MC) Causal inference encompasses the tools that allow social scientists to determine what causes what. In a messy world, causal inference is what helps establish the causes and effects of the actions being studied—for example, the impact (or lack thereof) of increases in the minimum wage on employment, the effects of early childhood education on incarceration later in life, or the influence on economic growth of introducing malaria nets in developing regions. Scott Cunningham introduces students and practitioners to the methods necessary to arrive at meaningful answers to the questions of causation, using a range of modeling techniques and coding instructions for both the R and the Stata programming languages.

Download or read book The Secret of Our Success written by Joseph Henrich and published by Princeton University Press. This book was released on 2017-10-17 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: How our collective intelligence has helped us to evolve and prosper Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals? This book shows that the secret of our success lies not in our innate intelligence, but in our collective brains—on the ability of human groups to socially interconnect and learn from one another over generations. Drawing insights from lost European explorers, clever chimpanzees, mobile hunter-gatherers, neuroscientific findings, ancient bones, and the human genome, Joseph Henrich demonstrates how our collective brains have propelled our species' genetic evolution and shaped our biology. Our early capacities for learning from others produced many cultural innovations, such as fire, cooking, water containers, plant knowledge, and projectile weapons, which in turn drove the expansion of our brains and altered our physiology, anatomy, and psychology in crucial ways. Later on, some collective brains generated and recombined powerful concepts, such as the lever, wheel, screw, and writing, while also creating the institutions that continue to alter our motivations and perceptions. Henrich shows how our genetics and biology are inextricably interwoven with cultural evolution, and how culture-gene interactions launched our species on an extraordinary evolutionary trajectory. Tracking clues from our ancient past to the present, The Secret of Our Success explores how the evolution of both our cultural and social natures produce a collective intelligence that explains both our species' immense success and the origins of human uniqueness.
Download or read book Cracks in the Ivory Tower written by Jason Brennan and published by Oxford University Press. This book was released on 2019 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ideally, universities are centers of learning, in which great researchers dispassionately search for truth, no matter how unpopular those truths must be. The marketplace of ideas assures that truth wins out against bias and prejudice. Yet, many people worry that there's rot in the heart of thehigher education business.In Cracks in the Ivory Tower, libertarian scholars Jason Brennan and Philip Magness reveal the problems are even worse than anyone suspects. Marshalling an array of data, they systematically show how contemporary American universities fall short of these ideals and how bad incentives make faculty,administrators, and students act unethically. While universities may at times excel at identifying and calling out injustice outside their gates, Brennan and Magness contend that individuals are primarily guided by self-interest at every level. They find that the problems are deep and pervasive:most academic marketing and advertising is semi-fraudulent; colleges and individual departments regularly make promises they do not and cannot keep; and most students cheat a little, while many cheat a lot. Trenchant and wide-ranging, they elucidate the many ways in which faculty and students alikehave every incentive to make teaching and learning secondary.In this revealing expose, Brennan and Magness bring to light many of the ethical problems universities, faculties, and students currently face. In turn, they reshape our understanding of how such high-powered institutions run their business.
Download or read book Accountability Frankenstein written by Sherman Dorn and published by IAP. This book was released on 2007-03-01 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: To understand the current moment in school accountability, one must understand the larger contradictions in education politics. Accountability Frankenstein provides a broader perspective on the school accountability debate by exploring the contradictions inherent in high-stakes testing. Accountability Frankenstein explains the historical and social origins of test-based accountability: the political roots of accountability, why we trust test scores while we distrust teachers, the assumptions behind formulaic accountability systems, and the weaknesses with the current carrot-and-stick approach to motivating teachers. Accountability Frankenstein answers the questions of educators and parents who want to understand the origins of accountability. This book challenges the beliefs of fierce advocates and opponents of highstakes testing. It provides a rescue plan for accountability after the failures of high-stakes testing, a plan to make accountability smart, democratic, and real.
Download or read book How Not to Be Wrong written by Jordan Ellenberg and published by Penguin. This book was released on 2015-05-26 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Witty, compelling, and just plain fun to read . . ." —Evelyn Lamb, Scientific American The Freakonomics of math—a math-world superstar unveils the hidden beauty and logic of the world and puts its power in our hands The math we learn in school can seem like a dull set of rules, laid down by the ancients and not to be questioned. In How Not to Be Wrong, Jordan Ellenberg shows us how terribly limiting this view is: Math isn’t confined to abstract incidents that never occur in real life, but rather touches everything we do—the whole world is shot through with it. Math allows us to see the hidden structures underneath the messy and chaotic surface of our world. It’s a science of not being wrong, hammered out by centuries of hard work and argument. Armed with the tools of mathematics, we can see through to the true meaning of information we take for granted: How early should you get to the airport? What does “public opinion” really represent? Why do tall parents have shorter children? Who really won Florida in 2000? And how likely are you, really, to develop cancer? How Not to Be Wrong presents the surprising revelations behind all of these questions and many more, using the mathematician’s method of analyzing life and exposing the hard-won insights of the academic community to the layman—minus the jargon. Ellenberg chases mathematical threads through a vast range of time and space, from the everyday to the cosmic, encountering, among other things, baseball, Reaganomics, daring lottery schemes, Voltaire, the replicability crisis in psychology, Italian Renaissance painting, artificial languages, the development of non-Euclidean geometry, the coming obesity apocalypse, Antonin Scalia’s views on crime and punishment, the psychology of slime molds, what Facebook can and can’t figure out about you, and the existence of God. Ellenberg pulls from history as well as from the latest theoretical developments to provide those not trained in math with the knowledge they need. Math, as Ellenberg says, is “an atomic-powered prosthesis that you attach to your common sense, vastly multiplying its reach and strength.” With the tools of mathematics in hand, you can understand the world in a deeper, more meaningful way. How Not to Be Wrong will show you how.

Download or read book Conning Harvard written by Julie Zauzmer and published by Rowman & Littlefield. This book was released on 2013-09-03 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2011 a 24-year-old man pled guilty to falsifying his application to Harvard University, bilking the world’s most prestigious university out of more than $45,000 in prizes and scholarships. Using forged SAT scores, transcripts, and letters of recommendation, Adam Wheeler outsmarted Harvard's admissions office and then went even further. Once accepted into the Ivy League he kept lying, cheating, and succeeding, winning thousands of dollars in prizes and grants. But then he shot too far. During his senior year, Wheeler applied for Rhodes and Fulbright scholarships, a gamble that finally exposed his extensive tangle of lies. Alerted that he was under suspicion, Wheeler fled Harvard but did not stop. He successfully filed more fraudulent applications at top-tier schools across the country, until some vigilant admissions officers, Massachusetts police, and even his own parents forced him off his computer and into court. As reporters for The Harvard Crimson, Julie Zauzmer and Xi Yu covered the case from the moment the news of Wheeler’s indictment broke. In the course of their reporting, they interviewed dozens of friends, roommates, teachers, and advisors who knew Wheeler at the many phases of his suspect academic career. Their fascinating account reveals how one serial scammer took on the competitive world of the Ivy League—and almost won.
