Bilingual Mathematics

在加拿大。有人讲英语,有人讲法语,于是加拿大就将英语和法语都定为自己的官方语言。其实,加拿大不仅仅在官方语言上实施“一国两制”,在度量单位上也是公制和英制交替使用。这给加拿大人生活带来了些许不便。Brad也常为之头疼。     

Driving in China

Brad夫妇今年来中国故地重游。看到如今城市里满大街的汽车代替了20年前比比皆是的自行车,感慨之余,也对中国马路上的交通状况甚是担忧。     

The Sorrows of Being Young

编者按：年轻,固然令人羡慕,却也是个容易彷徨困惑的年纪。脚下的路似乎很长,但到底会伸向何方？又该如何去走？Brad给出了他中肯的建议。     

Evaluation and publication delay in Ibero-American scientific journals

This article analyses the review, acceptance and publication dates of a sample of 21,890 articles from 326 Ibero-American scientific journals from all subject areas and countries included in the Latindex Catalogue 2.0 and published between 2018 and 2020 (freely available as an open access dataset). The aim is to discover evaluation and publication times. The evaluation process takes a median of 110 days, the publication process, a median of 82 days, and the whole process, a median of 224 days. Statistical differences are found according to periodicity, subject areas, countries, existence of a printed version and article type (Call for Papers or General articles). From the data we find that the delay in publication is longer than publishers themselves report to the DOAJ. STEM areas present the most similarity in publication patterns, having a higher number of evaluation days (Ed) than publication days (Pd); Arts and Humanities present the opposite pattern, with a higher Pd than Ed. In the case of Social Sciences, the times are similar. General articles and Call for Papers articles differ in terms of Ed, but not Pd, indicating that Call for Papers revisions are faster.

“They Were There for People Who Needed Them”: Student Attitudes Toward the Use of Trigger Warnings in Victimology Classrooms

Over the last five years, vigorous debate has been waged about the purpose, use, and impact of trigger warnings in courses offered at institutions of higher education. This debate has been largely uninformed by research findings. This study fills this gap using quantitative and qualitative data collected via surveys in a large undergraduate victimology course to explore student attitudes toward trigger warnings. Findings revealed considerable, but nuanced support for trigger warning use in victimology courses. Support does not appear to differ between crime victims and non-victims; support is higher among females than males. These findings underscore that universal decisions mandating or advocating for or against the use of trigger warnings are premature. Further study is needed with a diverse range of samples to gain a fuller picture of student attitudes about trigger warnings as well as to assess any impact of trigger warnings use on student behavior and learning.     

Undergraduate Medical Students' Usage and Perceptions of Anatomical Case-Based Learning: Comparison of Facilitated Small Group Discussions and eLearning Resources

While case-based discussions can empower students to apply knowledge to contextual clinical situations, scheduling these activities is a challenge in crowded curricula. Case-based eLearning activities, derived from existing cases discussed within anatomy small group tutorials, were created incorporating principles such as interactivity, reinforcement, and feedback. Over half of the students accessed one or more of these online cases, with 18% accessing all eight online cases provided. Access increased as the semester progressed, particularly just before summative examinations, implying students used these primarily as revision aides. Students rated both formats highly, but favored the online format with regard to enjoyment (P = 0.048), learning (P = 0.101), and feedback (P = 0.086). However, more students discussed these cases in small group tutorials within the anatomy dissecting room than completed them online (122 vs. 67) and themes emerging from free text comments included a desire to have more time dedicated to these cases during small group tutorials, and an appreciation for the opportunity for discussion with staff and learning through doing. Additionally, native English speakers rated the anatomy room discussions significantly higher in all aspects than non-native English speakers, suggesting that non-native speakers may be hesitant or reluctant to fully participate in front of peers. While online case-based learning activities are a useful adjunct to anatomy teaching, particularly for revision, assumptions that “digital natives” have an innate preference for digital resources require critical evaluation, as students still place a high value on opportunities for discussion with staff during their studies.
