The influence of interdisciplinary literacy on learning effects among college students: the mediating effects of online physical education on learning behavior

IntroductionThe development of high-quality physical education curriculums is required in the information age. Interdisciplinary literacy and student learning behavior are two significant factors that affect the quality of teaching and learning. This study explores the relationship between interdisciplinary literacy (IDL) and learning effects (LE) among Chinese college students during the COVID-19 pandemic, as well as the mediating effects of online physical education learning behaviors (OPELB). This research aims to provide a reference for the development of high-quality online physical education. MethodsThe study involved 691 college students from 10 general universities in Shaanxi Province as research subjects. Descriptive statistics, Pearson correlation analysis, multiple regression analysis and Bootstrap testing were used to evaluate the mediating effects. ResultsThere was a significant positive relationship between the three variables of IDL, OPELB, and LE (p < 0.001). Multiple regression analysis found that IDL significantly and positively predicted LE and OPELB (p < 0.001), and OPELB predicted LE (p < 0.001). IDL among college students had a total effect of 0.816 on LE, with OPELB accounting for 22.67% of the mediated effect. DiscussionThis study demonstrates that OPELB has a partial mediating effect on IL and LE, and stable IDL and OPELB improve LE. Therefore, teachers should pay attention to improving students' IDL while encouraging them to develop better OPELB to achieve satisfactory learning outcomes.

Software Engineers' Response to Public Crisis: Lessons Learnt from Spontaneously Building an Informative COVID-19 Dashboard

The Coronavirus disease 2019 (COVID-19) outbreak quickly spread around the world, resulting in over 240 million infections and 4 million deaths by Oct 2021. While the virus is spreading from person to person silently, fear has also been spreading around the globe. The COVID-19 information from the Australian Government is convincing but not timely or detailed, and there is much information on social networks with both facts and rumors. As software engineers, we have spontaneously and rapidly constructed a COVID-19 information dashboard aggregating reliable information semi-automatically checked from different sources for providing one-stop information sharing site about the latest status in Australia. Inspired by the John Hopkins University COVID-19 Map, our dashboard contains the case statistics, case distribution, government policy, latest news, with interactive visualization. In this paper, we present a participant's in-person observations in which the authors acted as founders of https://covid-19-au.com/serving more than 830K users with 14M page views since March 2020. According to our first-hand experience, we summarize 9 lessons for developers, researchers and instructors. These lessons may inspire the development, research and teaching in software engineer aspects for coping with similar public crises in the future.

Resident-performed immediate sequential bilateral cataract surgery during the COVID19 pandemic

Purpose : Minimizing healthcare-related exposures for patients and providers are paramount during the coronavirus (COVID-19) pandemic. We performed a retrospective cohort study to compare visual outcomes and patient satisfaction in senior residentperformed immediate sequential bilateral cataract surgery (ISBCS) versus delayed sequential bilateral cataract surgery (DSBCS). Methods : All ISBCS and DSBCS patients who underwent senior resident-performed cataract surgery in the Comprehensive Ophthalmology division of a single academic institution from May to September 2020 were included. Outcome measures were final corrected distance visual acuity (CDVA), final manifest refraction (MRx), incidence of intraoperative and postoperative complications, total number of clinical and surgical visits, and patient satisfaction, assessed postoperatively by telephone questionnaire. Results : Fourteen (22 eyes) and 28 (56 eyes) patients underwent senior residentperformed ISBCS and DSBCS, respectively. Final CDVA was 20/25 or better in 21 (95%) ISBCS eyes and 51 (91%) DSBCS eyes (p=0.670). The deviation of final MRx from target refraction was within 0.50 D in 17 (77%) ISBCS eyes and 47 (84%) DSBCS eyes (p=0.522). There was no significant difference in intraoperative (p=1.000) or postoperative (p=1.000) complications. ISBCS patients averaged 3.5 fewer visits than DSBCS patients (5.9 vs 9.5, p<0.001). All ISBCS and 20 DSBCS patients (87%) reported they were overall “very satisfied” or “satisfied” with their experience (p=0.701), and there was no significant difference in the overall visual function 7 score, where 0 indicates the worst possible functional impairment and 100 indicates no disability (p=0.561). Finally, five of the six senior residents who performed the ISBCS cases included in this study reported that they preferred performing ISBCS over DSBCS. Conclusions : This early experience demonstrates that senior resident-performed ISBCS is as safe and effective as DSBCS, with the added benefit of averaging fewer in-person visits for patients. Residency programs should consider offering senior resident-performed ISBCS to select patients during the COVID-19 pandemic.

Resident-driven telehealth visits after cataract surgery: Minimizing exposures during COVID-19

Purpose : During the coronavirus (COVID-19) pandemic, reducing unnecessary clinic visits is critical to limit risk of exposure for patients and providers. We hypothesized that final visual outcomes and postoperative complication rates in patients with postoperative week 1 (POW1) telehealth visits would be similar to patients with in-person POW1 visits in this retrospective cohort study. Methods : All uncomplicated cataract surgeries performed by senior residents with routine postoperative day 1 (POD1) exams and POW1 telehealth visits conducted from July 1, 2020 to December 31, 2020 at a single academic institution were reviewed. Controls were drawn from uncomplicated surgeries performed by senior residents with in-office POW1 visits during the same period the year prior (7/1/19 - 12/31/19). Visual outcomes, including final corrected distance visual acuity (CDVA) and deviation of manifest refraction from the target refraction, were compared between the two groups, along with rates of significant postoperative complications. Results : Thirty-eight patients (51 eyes) with POW1 telehealth visits and 44 patients (57 eyes) with POW1 in-office visits were included in the study. There were no statistically significant differences in baseline demographics or preoperative CDVA and biometry measurements between the two groups. The average final postoperative month 1 (POM1) logMAR CDVA was 0.030 and 0.021 (p=0.284) in the telehealth and in-office groups, respectively, with 44 (86%) telehealth eyes and 51 (90%) in-office eyes within 0.50 D of the target refraction (p=0.610). Six eyes (12%) in the telehealth group and 3 eyes (5%) in the inoffice group developed complications noted at the POM1 visit (p=0.222), comprised of pseudophakic cystoid macular edema (CME) or mild persistent/recurrent postoperative iritis. In all instances, the CME and iritis resolved with topical steroids and/or NSAIDs, with final CDVA 20/30 or better. Conclusions : There was no statistically significant difference in final CDVA, refractive outcomes, or postoperative complication rates in eyes undergoing POW1 telehealth as compared to in-office visits. In uncomplicated cataract surgeries, POW1 telehealth visits can be a safe and effective alternative to in-office visits to minimize exposure risks during the COVID-19 pandemic.
