National assessments suggest that many students do not display proficiency with fractions. Considering that time and materials are precious resources, many educators are looking to use technology to provide supplemental instruction with low demand on the instructor. The current study utilized a multiple-baseline design to examine the effects of the Motion Math: Bounce application on the fraction quantity comparison and number line placement skills of three fifth-grade students. Results indicate that Motion Math: Bounce improved the quantity comparison skills of all three participants and the number line skills of one participant. Additionally, all three participants made improvements from pre- to posttest on a measure of general fraction knowledge. Implications for future research and intervention implementation are discussed. 相似文献
AbstractTo determine the state of the cataloging job market, this study compares job advertisements from August 2016-August 2018 advertising for jobs with cataloging in the title, metadata in the title, and cataloging and metadata in the title. Given ongoing concerns about the impact of metadata jobs on the cataloging job market, this study asks the questions: Are cataloging jobs in fact “disappearing” and becoming metadata jobs? Are entry-level jobs disappearing, perhaps contributing to the idea that there is a lack of qualified catalogers? Is there a difference in position level between cataloging and metadata job advertisements that can account for a lack or perceived lack of available cataloging jobs? Are there more entry-level or mid/supervisory positions advertised? Are cataloging and metadata jobs really separate, or should they be considered one position called cataloging and metadata? 相似文献
The rise of the modern Black Lives Matter movement can be traced back to two key events, the 2012 death of Trayvon Martin and the 2014 death of Michael Brown. Research routinely showed that mainstream media’s narrative choices marginalize and delegitimize protesters and their causes, a pattern known as the protest paradigm. This study provides a longitudinal examination of how the same mainstream media system varied in their coverage of similar events and the degree to which journalists challenged the predicted paradigms conceptualized in other academic work. A content analysis of national newspaper coverage revealed that news before the judicial rulings focused on protesters’ tactics (violence versus peaceful) and changed to the realm of ideas (grievances and demands) after the assailants were considered not guilty of wrongdoing. No progression was found in legitimizing coverage of protests between the two cases. 相似文献
This study examined the theory of change of the ACT Raising Safe Kids parenting program, including whether intervention effects on children's behavior problems were explained by improvements in mothers’ reported parenting practices, as well as whether baseline child behavior problems moderated these relations. Adult mothers of 3-to 8-year-old Brazilian children were assigned to the intervention (n = 97) or control (n = 46) groups. Results showed that the intervention improved mothers' perceptions of their parenting practices (positive discipline, emotional and behavioral regulation, and communication). Intervention-induced reductions in children’s internalizing and externalizing behavior problems were mediated by improvements in mothers’ emotional and behavioral regulation. Program effects were strongest for children with high levels of baseline behavior problems. 相似文献
Multimedia pedagogical agents are on-screen characters that allow users to navigate or learn in multimedia environments. Several agents’ characteristics may moderate their instructional effectiveness, including appearance, gender, nonverbal communication, motion, and voice. Here, we conducted a meta-analysis to test hypotheses from diverse theories predicting the effects of these agents’ characteristics. We tested predictions of cognitive load theory, cognitive theory of multimedia learning, computers are social actors, social agency theory, uncanny valley, and the action observation network. Our meta-analysis of 32 effect sizes (N?=?2104) revealed a small overall effect (g+?=?0.20), showing that learning with multimedia pedagogical agents was more effective than learning without these agents. As predicted by the redundancy effect of cognitive load theory and the coherence principle of cognitive theory of multimedia learning, 2D agents (g+?=?0.38) tended to be more effective than 3D agents (g+?=?0.11). As predicted by the computers are social actors hypothesis, most of the agents’ characteristics, including nonverbal communication, motion, and voice, appeared not to moderate their effectiveness. We conclude that multimedia pedagogical agents help learning through multimedia, and that students may be able to learn similarly from different types of agents.
The development of gratitude in youth has received increasing attention during the past several years, and gratitude‐based interventions have often been recommended for use in schools. Yet, the empirical status of the correlates of gratitude and the effects of gratitude‐based interventions on youths’ outcomes remains unclear. The present study addressed this ambiguity by systematically reviewing and meta‐analyzing original empirical journal articles investigating gratitude in youth through September 2014 (N = 20). Findings from the meta‐analysis of correlates indicate small‐to‐moderate convergent and discriminant evidence for gratitude as a subjective well‐being indicator in youth, yet other results indicate that gratitude measures have relatively poor test–retest reliability and/or predictive validity and that they have questionable concurrent validity with other gratitude measures. Moreover, findings from the meta‐analysis of intervention outcomes indicate that gratitude‐based interventions are, as a whole, generally ineffective and that much more intervention research is warranted. Implications of these findings for theory, future research, and the practice of school psychology are discussed. 相似文献
In 2012, the Colorado State University Libraries’ Technical Services Department reorganized, which provided the catalyst to reconfigure paraprofessional staff positions. Staff are either part of the state classified system or are considered administrative professionals; both categories dictate the extent to which positions can be expanded to encompass assisting with managing electronic resources. This presentation is an account of how NASIG’s Core Competencies for Electronic Resource Librarians are scalable to be used in restructuring staff positions that assist with managing resources. Special attention will be paid to various modes of training that enable paraprofessionals to learn processes associated with electronic resources work. 相似文献
The article presents one of the main findings of an international study of 4,000 academic researchers that examined how trustworthiness is determined in the digital environment when it comes to scholarly reading, citing, and publishing. The study shows that peer review is still the most trustworthy characteristic of all. There is, though, a common perception that open access journals are not peer reviewed or do not have proper peer‐review systems. Researchers appear to have moved inexorably from a print‐based system to a digital system, but it has not significantly changed the way they decide what to trust. They do not trust social media. Only a minority – although significantly mostly young and early career researchers – thought that social media are anything other than more appropriate to personal interactions and peripheral to their professional/academic lives. There are other significant differences, according to the age of the researcher. Thus, in regard to choosing an outlet for publication of their work, young researchers are much less concerned with the fact that it is peer reviewed. 相似文献
