In four experiments, it was found that rats subjected to extinction of conditioned taste aversions readily reacquired these aversions when subjected to conditioning once again. Two of the present procedures were very similar to those used by Danguir and Nicolaides in unsuccessful attempts to obtain reconditioning of extinguished taste aversions.  相似文献

This study investigated whether or not an increase in secondary science teacher knowledge about evolution and the nature of science gained from completing a graduate-level evolution course was associated with greater preference for the teaching of evolution in schools. Forty-four precertified secondary biology teachers participated in a 14-week intervention designed to address documented misconceptions identified by a precourse instrument. The course produced statistically significant gains in teacher knowledge of evolution and the nature of science and a significant decrease in misconceptions about evolution and natural selection. Nevertheless, teachers’ postcourse preference positions remained unchanged; the majority of science teachers still preferred that antievolutionary ideas be taught in school.  相似文献

This article discusses the use of Wikipedia by academics and students for learning and teaching activities at Liverpool Hope University. Hope has distinctive aspects but we consider the findings to be indicative of Wikipedia use at other British universities. First we discuss general issues of Wikipedia use within the university. Second, we examine existing research on Wikipedia use amongst students and academics. Based upon a sample of 133 academics and 1222 students, our principal findings were: (1) 75% of academics and students use Wikipedia; (2) student use is typically confined to the initial stages of assessments; (3) a quarter of academics provide guidance on how to use Wikipedia and (4) 70% of academics use Wikipedia for background information for teaching purposes, something that it is not influenced by whether student use is tolerated or not. Our conclusion is that whilst Wikipedia is now unofficially integrated into universities, it is not ‘the’ information resource as feared by many and that an enlightened minority of academics have attempted to assimilate it into their teaching.  相似文献

Film has become a popular form of entertainment among teenagers and provides images from which teens model behaviors and form attitudes. This study addresses the understudied area of the portrayal of teen and adult sexual behaviors over nearly three decades in the top-grossing teen-centered films from 1980 to 2007. This study analyzes the frequency, nature, character portrayals, and consequences of sexual behavior. The results show that teen-centered films are replete with passionate kissing and sexual dialogue yet contain a modicum of implied intercourse and intimate touching. Moreover, the frequency of such occurrences has remained surprisingly constant over the last three decades. This research also reveals that teen-centered films, as a source for sexual socialization, are relatively impoverished when it comes to responsible messages dealing with abstinence, safe sex practices, and the health risks associated with sex.  相似文献

ABSTRACT

Prisoner reentry is an important and timely topic which can be challenging to research because it is so wide-reaching and includes so many subtopics. The aim of this guide is to outline the basic sources and necessary strategies to begin study in this area. The main part of this guide is a list of materials limited to those that have appeared since 2000. The second part of the guide gives direction to those who want to learn more, by recommending strategies including keywords and phrases which have been found to be of use. The issues related to prisoner reentry affect all of us. Public policy, legislative changes, and community survival require a knowledgeable citizenry. This guide can direct users to the information necessary to make meaningful decisions about these sometimes controversial issues.  相似文献
