Conclusion Computer simulations in genetics have the potential to complement laboratory activities and to act as an adjunct to the use of traditional sets of problems. In these roles, simulations such as CATLAB, generate qualitative changes in the learning experiences of students. For example, the simulated breeding experiment may be repeated and strategies modified without regard of the time and management constraints associated with actual laboratory experimentation; problem-solving may involve active data generation, in contrast to the style of textbook problems. This study showed that students reported a favourable attitude to CATLAB and that their use of the program lead to meaningful learning. The cognitive gains made by the student group encompassed both genetic concepts and processes. The scope for use of computer simulations as an adjunct to, or in some cases even replacement of traditional activities, and for an analysis of their impact is considerable.  相似文献

Five hundred graduates with learning disabilities (LD) from three universities in the United States completed a survey related to their postschool employment outcomes and experiences. The present study presents data related to their decisions regarding LD disclosure in employment settings. Although 73% of the respondents reported that the LD affected their job in some way, only 55% reported self-disclosing, and only 12% reported requesting accommodations. Specific reasons for each of these decisions are presented, as are areas in which LD affect work, strategies for dealing with LD in the workplace, and perceptions of the Americans with Disabilities Act. Implications for secondary and postsecondary programs are discussed.  相似文献

The Image of Science and Scientists Scale was developed to assess students' attitudes toward science. The instrument items are based on the 1957 summaries presented by Margaret Mead and Rhoda Metraux. The reliability of the instrument, using coefficient alpha, ranged from 0.76 in the pilot to 0.86 in the second phase of the study. Construct validity was obtained by comparing a science-oriented group versus a random sample to determine if the instrument could discriminate between the groups. With IQ controlled, the science group performed significantly higher (t = 2.58 ?p < 0.012). Furthermore, scores in ISSS contributed significantly to the prediction of science grades as determined by multiple regression analysis.  相似文献

ABSTRACT

One of the most important resources for social and family historians researching the former Russian Empire are the revision lists, a series of ten enumerations of the population conducted between 1719 and 1858. Listing the members of each household among taxable classes of people across the Russian Empire, the revision lists are useful for studying historical population demographics and reconstructing family relationships. An awareness of these records and where to access them can be useful for Slavic librarians to facilitate the research of Russian historians and genealogists. This article provides an overview of the history and content of the revision lists with a survey of available collections online and offline.  相似文献

People in a society share collective memories about numerous historical events simultaneously, but not every event is equally salient all the time. This study examines the implications of memory mobilization on recall of historical events. Memory mobilization is treated as a process that involves communication activities via a wide range of platforms. Focusing on Hong Kong people's memory of the 1989 Tiananmen Incident in Beijing, this study found that more people recalled the event during the period of memory mobilization, and communication activities involving interpersonal exchanges were related to recall of Tiananmen mainly in that period. In addition, the findings showed that the process of memory mobilization operated differently for different age cohorts. The theoretical implications of the findings are discussed.  相似文献
