Learning to read and understand research articles (primary literature) is an important step in the enculturation of higher education students into the scientific community. We presume, based on ideas from the field of genre analysis, that it is important for the development of reading skills to become conscious of the rhetorical structures in research articles. So, we determined how well science students are able to identify 2 important elements of this rhetorical structure: conclusions and grounds. First-year undergraduate life science students who followed a course called ‘Biomedical Research’ made assignments in which they had to identify these 2 elements. We analysed the answers of 20 students in detail and compared their answers with 2 expert readers. Furthermore, we conducted task-based interviews with 4 students to gain more insight into their reading strategies and to determine how they identify conclusions and grounds. Our results show that students and experts defined conclusions and grounds in different ways. Students and experts agreed on the most important conclusion of the articles. However, students identified a wide range of sentences which were not seen as conclusions by the experts. The grounds students mentioned mostly matched their conclusions. Students sometimes failed to mention important grounds for a particular conclusion. In conclusion, our study shows the differences between student and expert readers of primary literature. Based on our results, we formulated criteria for the design of a teaching strategy that aims to improve students' skills for reading primary literature. 相似文献

The purpose of this research was to examine the effects of hierarchical communication distortion on the task role perceptions of subordinates working in the context of a goal setting program. The study used empirical data collected from junior officers, managers, staff employees (N=32) and their executive supervisors (N=15) in one division of a national insurance company. This sample formed 32 supervisor‐subordinate dyads which were classified as “high” or “low” in hierarchical communication distortion. Subordinates in “high” distortion dyads experienced more role stress in terms of conflict and ambiguity than did subordinates in “low” distortion dyads. 相似文献

在情境中使用的否定,是相干否定;在世界中使用的否定,是经典否定.我首先给定了两个逻辑,一个是信息的基础相干逻辑L1,另一个是与L1联系紧密的逻辑系L2.其中,L2被同时包含世界和情境两者的类模型所刻画.当我们只考虑某个L2模型中包含情境的部分(连同可达关系,不相容关系,以及可分辨情境的集合)时,我们将得到一个L1的模型结构.在给定了一些关联L1的模型结构与可能世界的直觉条件后,我们得到了一类特殊的模型--被这类模型刻画的逻辑可以合理地将相干否定与经典否定关联,并且允许我们认为此二者是相容的.在这篇文章中,我首先给定了一个简单的信息逻辑--一个非常弱的相干逻辑.然后,我尝试对其中的命题联结词的真值条件使用经典的处理.以上处理我分两步完成.首先,使用Routley-Meyer的语义以及相关的信息解释.然后,我给出了另一个能够整合环境(或情境)与可能世界之间关系的逻辑.这一关系,可以理解为信息与真之间的形而上的关联.在文章的最后,我将指出在在相干逻辑中整合经典否定的好处. 相似文献

People with disabilities need access to emergency-related information at the same time that the general public receives that information. Many county and municipal-level governments suggest that citizens sign up on a Web page to receive emergency alert information. While the messages being sent out via e-mail or text message might be accessible, the sign-up processes are often inaccessible, preventing people with disabilities for signing up for these important information services. In this paper, all of the county-level emergency alert sign-ups in Massachusetts, New York, and Maryland, were evaluated for accessibility. A total of 156 evaluations took place (6 evaluations for each of the 26 counties evaluated). Of the 26 counties evaluated, 21 of them had accessibility violations. Legal, policy, and design-related implications are presented in the following discussion. 相似文献

Two hundred Gulfport, Mississippi, first grade students received the benefit of extensive and intensive treatments designed to enhance educational effect. Approximately half of these students were from definitely deprived backgrounds and many demonstrated a very low degree of readiness for first grade activities. Comparison classes following the established first grade curriculum were also monitored to provide a basis for comparison. Results strongly suggest that the experimental treatments resulted in higher achievement. More important than the direction of the observed differences are their magnitudes. Enhancement of achievement due to the experimental treatments appeared greatest for low readiness students by a wide margin. 相似文献

The peer nomination technique was investigated as a predictor of academic success among members of a college freshman class. The technique provided scores which were reliable and which were valid against a grade point ratio criterion. The peer nomination scores were shown to tap variance independent of SAT scores and, therefore, their applicability was suggested in academic counseling as a predictor which can be used to identify students who may face academic difficulties. 相似文献
