Individual versus pair work on L2 speech acts: production and cognitive processes

This study aims to examine the extent to which peer collaboration affects EFL learners’ speech act production and cognitive processes. Eleven EFL students in the individual group and 22 students (11 pairs) in the collaborative groups were asked to report their cognitive processes when working on a written discourse completion task (WDCT). The WDCT performances were rated on a five-point Likert-type scale, and the verbalizations were analyzed in terms of pragmatic-related episodes (PREs). Results showed that the individual group scored higher on content, whereas the collaborative group outperformed their counterparts on forms. Regarding the cognitive processes, the individual group tended to plan the general direction of their writing before writing the WDCT and paid more attention to sociopragmatic content while writing. In contrast, the collaborative group planned specific details before the task and attended to pragmalinguistic forms more often while writing.

The Algae Society BioArt Design Lab: Exploring multispecies entanglements and making kin with algae

The Algae Society BioArt Design Lab is a global collective of interdisciplinary researchers working together with algae as non-human international research partners. As a collaborative group of artists, scientists and scholars, they experiment and co-produce with algae, seeking to highlight complex human interdependence and kinship with algal beings. Here they introduce the Algae Society and share a collective collage of their evolving artistic works while reflecting on each researcher's process, materiality, and aesthetic considerations. With these works, they endeavor to shift our perspectives from human-centric exceptionalism to greater appreciation and cultural reframing of our responsibility as participants in multispecies worlding.

LinkAGES Colorado: Evaluation of Intergenerational Programs to Improve Connections Across All Ages

LinkAGES: Colorado is a collaborative group of multi-sector organizations (e.g., libraries, non-profit service organizations, nursing homes) that uses a capacity-building approach to support the offering of intergenerational programs and evaluation of outcomes over time and across programs. Since 2018, LinkAGES has implemented 20 intergenerational programs involving various activities (e.g., music and art therapy, sharing cultural traditions), across settings, and across modalities (in-person and online). Ages of program participants ranged from 5 months to 96 years old. This study evaluated change in connectedness between generations over time. Participants (n=118) completed pre- and post-program ratings on social connection (i.e., level of intergenerational engagement, self-perception of extent of feeling connected, and self-perception of impact on someone from another generation) on a 4-point Likert scale. Paired sample t-test results indicated that programs significantly improved engagement and perceived impact. Using multiple regression analyses, we tested change over time for each outcome controlling for participant age group, program host setting, and program modality. A greater positive change in level of engagement occurred for older adults and in-person programs. Additionally, feelings of connection and perceived impact significantly improved over time when controlling for age group, program modality, and program host setting, with age group as a significant covariate. This study demonstrates the impact of intergenerational programs on social connectedness across a wider network of organizations than much of the extant literature. While the positive outcomes are promising and consistent across LinkAGES programs and existing literature, further exploration of age group differences should be considered.

Construction and Evaluation of a Virtual Reality Laparoscopic Surgery Collaborative Training Platform: Taking Laparoscopic Cholecystectomy as an Example

Backgroud: Virtual reality (VR) technology represents the future of medical education due to its unique advantages, especially with the Covid-19 pandemic lasting. We developed a laparoscopic VR surgery collaborative training platform hoping to shed light on future medical education in China.Methods: We constructed a VR surgery training platform and designed surgery curriculum on laparoscopic cholecystectomy (LC). 36 first-year postgraduate students in China standardized training program for resident doctor (C-STRD) from the Third Xiangya Hospital of Central South University were enrolled for validation trials. In the Phase I trial, 12 students performed LC in the exploration mode. After training in the surgery learning mode, they performed LC again. The LC scores before and after training were compared. In the Phase II trial, another 12 students were randomly assigned to either the collaborative group or the control group. The former trained with a senior surgeon collaboratively in the surgery learning mode and then performed LC alone in the exploration mode. The latter trained in the surgery learning mode by themselves and performed LC in the exploration mode. The LC scores between groups were compared. The user experience (intention to use, skills improvement, usability, degree of enjoyment) were analyzed through questionnaires from the above 24 students. Interest in surgery learning of Phase I students was compared with 12 students who didn’t experience the VR platform.Results: In Phase I trial, the mean LC scores of the students were elevated from 56.83 to 61.17 (p=0.042) after learning in surgery learning mode. In Phase II trial, collaborative group students had higher scores than their rivals (67.17 vs 61.33, p=0.014). Most students have a positive users’ experience regarding the intention to use and skills improvement. Collaborative group students had higher evaluation regarding usability. Students who experienced the VR platform were significantly more interested in future surgery learning (3.60 vs 2.58, p <0.05).Conclusion: Our study constructed a VR platform for collaborative surgery training, which showed an excellent training effect. Medical students rated the platform highly, and their interest in learning increased.
