However, this progress isn't always as smooth as it's sometimes assumed to be. Take for example the case of thalidomide, that infamous drug from the 1950s. For those not old enough to remember the story, thalidomide was marketed as a sedative and treatment for morning sickness. While it was never approved for sale in the United States, it was considered so safe in Germany that it was sold as an over-the-counter medication. Then obstetricians began to see an increase in babies born with phocomelia or \"seal limb,\" where the long bones of one or both pairs of limbs fail to develop correctly. These children had limbs that looked like seal flippers: hands or feet attached to the trunk.\u0000\u0000Phocomelia can be caused by a genetic abnormality, but it is rare. If an obstetrician saw a patient with this defect, it was the type of unusual event to share with a colleague, and the coincidence of one or more colleagues also recently seeing such children led to an investigation into why the abnormality was suddenly becoming more common. It turned out that almost every woman who gave birth to a baby with phocomelia had taken thalidomide early in pregnancy. In all, about 10,000 children, mostly in Europe, were born with the defect before the drug was taken off the market. In the United States, a physician at the Food and Drug Administration had questioned the drug's safety on the grounds of its nervous-system side effects during trials. This slowed its approval long enough that its other flaws were discovered before it could be distributed. \u0000\u0000The lingering effects of thalidomide are still seen in the now older adults who have lived their …","PeriodicalId":50960,"journal":{"name":"American Biology Teacher","volume":"315 1","pages":"426-429"},"PeriodicalIF":0.5,"publicationDate":"2011-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78379982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many state and federal government forms ask you to identify your \"race.\" Among the popular options are \"Caucasian,\" \"Hispanic,\" \"Black,\" \"Asian,\" \"Pacific Islander,\" and \"American Indian.\" But I do not check any of those and instead write on the blank provided \"Human.\"\u0000\u0000Why? Because all humans are one race: Homo sapiens . There is absolutely no genetic or evolutionary justification for \"racial\" categories of humans. The concept of race was conceived hundreds of years ago by whites to justify the belief that \"the white race\" was superior to others. For example, in South Africa, the apartheid movement begun in 1948 by the British and Dutch was practiced primarily to separate whites from other ethnic groups and to create a hierarchy of human superiority. This legal form of racial segregation created the categories \"white,\" \"colored\" (i.e., any mix between whites and blacks), and \"black,\" meaning native African. The presumption was that whites were superior to colored and colored superior to blacks. This ridiculous division had no genetic basis and, fortunately, ended in 1993 as a result of the brave efforts of Nelson Mandela and others. \u0000\u0000Here is the biological problem with race. The genetic variation within each of the various ethnic groups of Homo sapiens is greater than that between the various ethnic groups. We are one race, just as dogs ( Canis familiaris ), house cats ( Felis domesticus ), and horses ( Equus caballus ) are. Obviously there are many different breeds of all of these animals and they often have striking differences. (Compare a Saint Bernard with a Chihuahua for an analogy of different human ethnic groups.) Furthermore, the origin of breeds or ethnic groups is more …","PeriodicalId":50960,"journal":{"name":"American Biology Teacher","volume":"17 1","pages":"379-380"},"PeriodicalIF":0.5,"publicationDate":"2011-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80141050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By Duane F. Shell, David W. Brooks, Guy Trainin, Kathleen M. Wilson, Douglas F. Kauffman and Lynne M. Herr . 2009. Springer (ISBN 9789048132140). 211 pp. Hardcover. $139.00. \u0000\u0000This is an excellent book about how learners learn and behave in a classroom and how this understanding about learning could be put to use by teachers for effective teaching. The authors present the Unified Learning Model (ULM), which is based on three basic principles of learning, namely working memory allocation, prior knowledge, and motivation. The book is divided into two parts. In the first, the basic principles of ULM that cause learning are described in detail, and in the second part application of the model to develop effective teaching and learning strategies is discussed. There are several learning theories and models in contemporary education literature that have created conflicts and confusion in the minds of teachers and education researchers because these theories use different vocabulary and explain only certain aspects of learning phenomena. The ULM is an attempt to connect different learning theories and encompass almost all the aspects of learning. The authors explain with clarity the three basic principles of learning and their connection to form the ULM.\u0000\u0000The first chapter is a brief introduction to the ULM. In chapter 2, \"Learning,\" the authors do an excellent job of explaining …","PeriodicalId":50960,"journal":{"name":"American Biology Teacher","volume":"25 1","pages":"248-249"},"PeriodicalIF":0.5,"publicationDate":"2011-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90327548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
