The goal of this study was to explore the processes of group role formation in online class settings. Qualitative analysis was used to code chat logs and discussion threads in six undergraduate Family and Consumer Sciences online courses that required online group projects. Four themes related to the process of group role formation emerged: testing the waters, apologies as being nice, tag – you’re it, and struggling to find one’s role. Students created roles of leader, wannabe, spoiler, agreeable enabler, coat‐tails, and supportive worker as the group process evolved over the course of the semester. Results lend support for a balance between allowing students to create and experience roles on their own and faculty assignment of roles. Questions are raised related to faculty approaches toward directing and scaffolding the group process. 相似文献

This paper presents a game of industrialisation, based on a paper airplane, that mimics real world production ramp-up and blends classical engineering courses together. It is based on a low cost product so that it can be mass produced. The game targets graduate students and practitioners in engineering fields. For students, it offers an experiment in which methods learned in separate courses can be applied. For practitioners, it affords an opportunity to engage in reflexive practices related to industrialisation. Both students and practitioners are able to experience integrated management, required by industrialisation, in a controlled environment: the laboratory. 相似文献

Greek engineering Schools have a high status and attract good students. However, we show that in the leading institution, the National Technical University of Athens, only 27% of the students admitted in 1992–2003 graduated after the nominal five years study: the median graduation time was 73 months (reaching 93 months in one School) and 12% are predicted never to graduate at all, most without withdrawing officially. Results differ between Schools, between routes of admission and by gender (females being better than males). Systematic study of reasons for not completing or delay in completing studies is urgently needed. Overall, 4% of the students withdraw officially during their first year. The percentage of withdrawals by School is negatively correlated with the percentage that gave that School as first choice in the entrance procedure, indicating problems in the admission system. 相似文献

Recent studies conclude that teachers are important for student learning but it remains uncertain what actually determines effective teaching. This study directly peers into the black box of educational production by investigating the relationship between lecture style teaching and student achievement. Based on matched student-teacher data for the US, the estimation strategy exploits between-subject variation to control for unobserved student traits. Results indicate that traditional lecture style teaching is associated with significantly higher student achievement. No support for detrimental effects of lecture style teaching can be found even when evaluating possible selection biases due to unobservable teacher characteristics. 相似文献

Two frequently-used discussion protocols were investigated as part of a program to implement teaching cases in undergraduate educational psychology classes designed for preservice teachers. One protocol involved synchronous face-to-face (FTF) discussion of teaching cases, which occurred in class after students had individually completed written case analyses as homework outside of class. The other was asynchronous computer-mediated (CM) discussion taking place outside of class, simultaneous to students’ completion of their written case analyses. Six class offerings of an undergraduate child development course taught by two instructors (three classes by each instructor) were randomly assigned within instructor in a quasi-experimental design to one of the three discussion conditions: FTF, CM, or no discussion of the cases across the semester. Findings indicated that both CM and FTF discussion conditions were associated with positive outcomes relative to the control condition. Both CM and FTF discussion related to higher cognitive–affective engagement with the cases than the control condition; and the CM discussion condition was associated with higher cognitive–affective engagement than FTF discussion. In contrast, FTF discussion, but not CM discussion, was associated with higher-than-control-condition case analysis ability at the end of the semester. Potential explanations for these findings and directions for future research are discussed. 相似文献

Altmetrics have been proposed as a way to assess the societal impact of research. Although altmetrics are already in use as impact or attention metrics in different contexts, it is still not clear whether they really capture or reflect societal impact. This study is based on altmetrics, citation counts, research output and case study data from the UK Research Excellence Framework (REF), and peers’ REF assessments of research output and societal impact. We investigated the convergent validity of altmetrics by using two REF datasets: publications submitted as research output (PRO) to the REF and publications referenced in case studies (PCS). Case studies, which are intended to demonstrate societal impact, should cite the most relevant research papers. We used the MHq’ indicator for assessing impact – an indicator which has been introduced for count data with many zeros. The results of the first part of the analysis show that news media as well as mentions on Facebook, in blogs, in Wikipedia, and in policy-related documents have higher MHq’ values for PCS than for PRO. Thus, the altmetric indicators seem to have convergent validity for these data. In the second part of the analysis, altmetrics have been correlated with REF reviewers’ average scores on PCS. The negative or close to zero correlations question the convergent validity of altmetrics in that context. We suggest that they may capture a different aspect of societal impact (which can be called unknown attention) to that seen by reviewers (who are interested in the causal link between research and action in society). 相似文献

Drawing on anniversary-edition articles and interviews with journalists at Jakarta Post, Indonesia’s largest English-language news outlet, we argue that language of publication directly informs the narratives a journalistic interpretive community [Zelizer, Barbie. 1993. “Journalists as Interpretive Communities.” Critical Studies in Mass Communication 10: 219–237] develops to position itself as a news authority. Analysis showed that associations with English as a foreign language in Indonesia influenced stories of the newspaper’s professional values and practice, and the ways it conceptualized readership. The study contributes to the growing body of literature that examines intersections of journalism and language—in this case, English as a language of publication in a global context. 相似文献

This study reports the results of a needs analysis of literacy programs for a library system serving three rural and suburban
counties. It examines the computing skills and needs of literacy tutors as well as native-speaking and English language learner
(ELL) literacy tutees enrolled in the programs. Paper surveys were mailed to tutors, who were asked to complete a survey themselves
and assist their tutees to complete one. Results of this study offer insights into the incorporation of digital literacy into
traditional adult literacy programs focusing on the needs, wants, and support systems of user groups. 相似文献

Zebra finch song behavior is sexually dimorphic: males sing and females do not. The neural system underlying this behavior is sexually dimorphic, and this sex difference is easy to quantify. During development, the zebra finch song system can be altered by steroid hormones, specifically estradiol, which actually masculinizes it. Because of the ease of quantification and experimental manipulation, the zebra finch song system has great potential for use in undergraduate labs. Unfortunately, the underlying costs prohibit use of this system in undergraduate labs. Further, the time required to perform a developmental study renders such undertakings unrealistic within a single academic term. We have overcome these barriers by creating digital tools, including an image library of song nuclei from zebra finch brains. Students using this library replicate and extend a published experiment examining the dose of estradiol required to masculinize the female zebra finch brain. We have used this library for several terms, and students not only obtain significant experimental results but also make gains in understanding content, experimental controls, and inferential statistics (analysis of variance and post hoc tests). We have provided free access to these digital tools at the following website: http://mdcune.psych.ucla.edu/modules/birdsong. 相似文献

Today's doctoral programs continue to prepare students for a traditional academic career path despite the inadequate supply of research-focused faculty positions. We advocate for a broader doctoral curriculum that prepares trainees for a wide range of science-related career paths. In support of this argument, we describe data from our survey of doctoral students in the basic biomedical sciences at University of California, San Francisco (UCSF). Midway through graduate training, UCSF students are already considering a broad range of career options, with one-third intending to pursue a non-research career path. To better support this branching career pipeline, we recommend that national standards for training and mentoring include emphasis on career planning and professional skills development to ensure the success of PhD-level scientists as they contribute to a broadly defined global scientific enterprise. 相似文献
