In terms of positioning a student for Ph.D. admission, the decision to complete a thesis or comprehensive exams as one's M.A. capstone is based on much speculation, but little systematic study. This study surveyed M.A. and Ph.D. Communication program representatives about doctoral programs' admission preferences and practices regarding applicants holding M.A.s from other institutions, as well as perceptions of their institution's students' actual capstone choices. In nearly half the cases, doctoral program representatives were unaware of whether students admitted with M.A.s had elected the thesis, comprehensive exams, or some other capstone option. Additionally, the results show that Ph.D. programs prioritize students' writing samples, statements of reasons, and GRE scores when deciding admission. There were discrepancies between M.A. program representatives' perceptions of what information weighed most heavily with doctoral admissions committees and the priorities reported by Ph.D. program representatives. 相似文献

This study examined workplace romantic relationship partners’ e‐mail practices and perceptions. Results suggest that the relationship may play an integral role in determining participants' uses and perceptions of e‐mail Workplace romantic couples used e‐mail as frequently as face‐to‐face communication to interact with romantic partners and rated it as both rich and important Participants used e‐mail for both work‐related and social tasks. In addition, participants used business e‐mail addresses for communicating with relational partners and perceived that few organizational policies existed regarding its use. Theoretically, these findings suggest the importance of studying the relationship as a factor that affects e‐mail practices and perceptions. Practically, results indicated that e‐mail may present an additional channel for enhancing communication and connectedness in workplace romantic relationships, and that organizations may need to reflect more carefully about policies concerning e‐mail use in the workplace. 相似文献

Critical thinking skills are required to successfully navigate the overwhelming amount of information sources available today. To address the challenge of developing critical thinking skills, this empirical study examines the effectiveness of exercises in developing thinking skills in college freshmen students. The workbook exercises were designed to develop specific skills related to academics and critical thinking. Two groups of college freshmen participated in the study: one group was given the workbook, the other group was not. At the end of the semester, both groups completed a critical thinking assessment test. A comparison of the test scores confirms the effectiveness of these exercises on improving the critical thinking skills of college freshmen. 相似文献

Search engine optimization, or the practice of designing a web site so that it rises to the top of the results page when users search for particular keywords or phrases, has become so prevalent on the modern web that it has a significant influence on Google search results. This article examines the techniques used by search engine optimization practitioners, the difference between “white hat” and “black hat” optimization tactics, and why it is important for library staff to understand these techniques and their impact on search engine results pages. It also looks at ways that library staff can help their users develop awareness of the factors that influence search results and how to better assess the quality and relevance of results listings. 相似文献

Research supports an explicit-reflective approach to teaching about nature of science (NOS), but little is reported on teachers’ journeys as they attempt to integrate NOS into everyday lessons. This participatory action research paper reports the challenges and successes encountered by an in-service teacher, Sarah, implementing NOS for the first time throughout four units of a community college biology course (genetics, molecular biology, evolution, and ecology). Through the action research cycles of planning, implementing, and reflecting, Sarah identified areas of challenge and success. This paper reports emergent themes that assisted her in successfully embedding NOS within the science content. Data include weekly lesson plans and pre/post reflective journaling before and after each lesson of this lecture/lab combination class that met twice a week. This course was taught back to back semesters, and this study is based on the results of a year-long process. Developing pedagogical content knowledge (PCK) for NOS involves coming to understand the overlaps and connections between NOS, other science subject matter, pedagogical strategies, and student learning. Sarah found that through action research she was able to grow and assimilate her understanding of NOS within the biology content she was teaching. A shift in orientation toward teaching products of science to teaching science processes was a necessary shift for NOS pedagogical success. This process enabled Sarah’s development of PCK for NOS. As a practical example of putting research-based instructional recommendations into practice, this study may be very useful for other teachers who are learning to teach NOS. 相似文献

The language children hear presents them with a multitude of co-occurrences between words and things in the world, and they must repeatedly determine which among these manifold co-occurrences is relevant. Social factors—such as cues regarding the speaker's referential intent—might serve as one guide to whether word-object covariation should be registered. In 2 studies, infants (15–20 months and 18–20 months in Studies 1 and 2, respectively) heard novel labels at a time when they were investigating a single novel object; in one case the label was uttered by a speaker seated within the infant's view and displaying concurrent attention to the novel toy (coupled condition), whereas in the other case the label emanated from a speaker seated out of the infant's view (decoupled condition). In both studies, subsequent comprehension questions indicated that infants of 18–20 months registered a stable link between label and object in the coupled condition, but not in the decoupled condition, despite the fact that covariation between label and object was equivalent in the 2 conditions. Thus, by 18–20 months children are inclined to establish a mapping between word and object only when a speaker displays signs of referring to that object. 相似文献
