The pervasiveness of mobile devices in families’ homes has dramatically changed the physical and temporal arrangement of co-viewing media content; the representative image of American families seated around a TV set is an anachronism. But understanding and describing contemporary co-participation arrangements around digital media is challenging because of the mobile nature of these activities. As researchers, our greatest challenge is to observe people's digital media use that is increasingly ‘on-the-move’ in an effort to understand the significance and possibilities these devices have in family life, learning, and engagement in and across different settings. This article describes an innovative study design for understanding how mobile technologies influence the ways in which families learn together. We analyze the movement of digital media practices, where they are located, and how digital co-participation within families is distributed across time and space.  相似文献

Achievement goal theory suggests that goal orientations and the perceived motivational climate may influence one another and other motivational variables over time. Therefore, the purpose of this study was threefold: (a) to examine the relationship between perceived motivational climate and goal orientations over time (b) to investigate how goal orientations may fluctuate when the climate was in opposition to the initial goal orientation, (c) to determine how the climate may impact practice strategies. A set of inventories was administered to 162 college students at preselected times throughout several 16-week physical activity classes. Changes occurred in students' goal orientations, particularly when the perceived motivational climate was in opposition to their goal orientation. Aspects of the task-involving climate positively predicted practice strategies.  相似文献

Since 2001 the National Science Foundation’s ADVANCE program has distributed over $130 million in grants to improve work climate, enhance professional success, and increase recruitment and retention of female faculty in STEM fields. The process by which each institution designs and implements these interventions is seldom studied, however. Using climate surveys, administrative records, and a difference-in-differences regression approach, we assessed whether exposure to the design and implementation process helps explain improvements in climate and retention during the early years of ADVANCE implementation. We found that departments wherein at least one faculty member participated in ADVANCE committee work experienced significant improvements in job satisfaction among female faculty members and significant reduction in turnover among female full professors, suggesting that the ADVANCE design process was itself an intervention.  相似文献

Libraries depend upon student workers to assist in the day-to-day operations of a unit. The range of activities varies, as does the amount of flexibility given to students to go beyond the routine. This case study details an approach that was shaped based on student input and creative brainstorming to engage and involve student workers in new ways as well as strategies to elevate their leadership roles. The approach encourages students to contribute their particular strengths and expertise in ways that not only enhance the library's mission but also elevate their experience at the library.  相似文献

To improve search engine effectiveness, we have observed an increased interest in gathering additional feedback about users’ information needs that goes beyond the queries they type in. Adaptive search engines use explicit and implicit feedback indicators to model users or search tasks. In order to create appropriate models, it is essential to understand how users interact with search engines, including the determining factors of their actions. Using eye tracking, we extend this understanding by analyzing the sequences and patterns with which users evaluate query result returned to them when using Google. We find that the query result abstracts are viewed in the order of their ranking in only about one fifth of the cases, and only an average of about three abstracts per result page are viewed at all. We also compare search behavior variability with respect to different classes of users and different classes of search tasks to reveal whether user models or task models may be greater predictors of behavior. We discover that gender and task significantly influence different kinds of search behaviors discussed here. The results are suggestive of improvements to query-based search interface designs with respect to both their use of space and workflow.  相似文献

The present study examined the influence of schooling during children's first and second years of preschool for children who experienced different amounts of preschool (i.e., one or two years), but who were essentially the same chronological age. Children (n = 76) were tested in the fall and spring of the school year using measures of self-regulation, decoding, letter knowledge, and vocabulary. Using hierarchical linear modeling (HLM), preschool was not associated with children's development of self-regulation in either year. For decoding and letter knowledge, children finishing their second year of preschool had higher scores, although both groups of children grew similarly during the school year. Thus, our results suggest that the first and second years of preschool are both systematically associated with decoding and letter knowledge gains, and the effects are cumulative (two years predicted greater gains overall than did one year of preschool). Finally, children's chronological age, and not whether they experienced one versus two years of preschool, predicted children's vocabulary and self-regulation outcomes. Implications for preschool curricula and instruction are discussed, including the increasing emphasis on literacy learning prior to kindergarten entry and the need to address self-regulation development along with academic learning.  相似文献

Recent studies question the effectiveness of a traditional university curriculum in helping students improve their critical thinking and scientific literacy. We developed an introductory, general education (gen ed) science course to overcome both deficiencies. The course, titled Foundations of Science, differs from most gen ed science offerings in that it is interdisciplinary; emphasizes the nature of science along with, rather than primarily, the findings of science; incorporates case studies, such as the vaccine-autism controversy; teaches the basics of argumentation and logical fallacies; contrasts science with pseudoscience; and addresses psychological factors that might otherwise lead students to reject scientific ideas they find uncomfortable. Using a pretest versus posttest design, we show that students who completed the experimental course significantly improved their critical-thinking skills and were more willing to engage scientific theories the general public finds controversial (e.g., evolution), while students who completed a traditional gen ed science course did not. Our results demonstrate that a gen ed science course emphasizing the process and application of science rather than just scientific facts can lead to improved critical thinking and scientific literacy.  相似文献

The continuity of the liquid and gaseous states, and the existence of critical temperatures for specific gases, was discovered by Thomas Andrews in 1861. This had important implications for the liquefaction of the supposedly ‘permanent’ gases and the creation of an important new industry. Currently, the chemistry of reactions in supercritical fluids, especially water, is the subject of much research, especially in the context of treating industrial waste.  相似文献

The current study has a twofold purpose: first, to determine the reliability of a tool for assessing orthographic development in Spanish; second, to assess differences in students’ performance on the measure across multiple types of primary schools in a large city in Chile. A Spanish developmental spelling inventory that contained words of increasing orthographic difficulty was administered twice to students in first through fifth grades in three types of schools: public, private and partially subsidised. These school types in large part represent varying levels of student socio-economic status because of costs associated with attending them. Results demonstrate that (a) the Spanish spelling inventory is able to reliably measure the development of orthographic knowledge in Spanish, and (b) there is a relationship between school type and student achievement. The authors describe individual cases to highlight the qualitative nature of differential performance for students in greater- or lesser-resourced schools.  相似文献
