Ethical mediarhetoric in videogame cybertexts: procedural explication of moral topics in an educational context

Introduction. Education in the field of ethics and practical philosophy is important both within the framework of educational and disciplinary discourse and in terms of personal and social formation of a person, his/her value-behavioral system of coordinates. Video game cybertexts containing moral themes in their narrative and procedural structure can increase interest in the study of theoretical issues of ethics and create a special virtual-simulative space of moral experimentation. Materials and Methods. The theoretical part of the paper is based on the conceptual framework of understanding video games as a procedural cybertext formulated by E. Aarseth and I. Bogost. The operation of the multimodal-semiotic structure of video games is based on the ideas of J. Havreljak and W. Toch. The experimental cluster of work is realized on the principles of Digital Game-Based Learning developed by M. Prensky and a set of pedagogical practices on the use of ICT-based learning. Results. Based on the interpretation of the features of multimodal semiotics of ethically engaged video games, two modes of their distinction are revealed – narrative and gameplay. Narrative represents moral themes through narrative storytelling, and gameplay through gameplay. It has two forms of manifestation and certainty - external-iconic (based on visual reading and ethically binary interpretation of videogame cybertext) and procedural, where at the level of program architectonics the possibilities of choice and realization of simulations of ethical activities are created. The experiment allowed a radical change for the better (from 20% to 73%) in most students' expectations about the educational possibilities of video games in this disciplinary area. The DGBL methodology helped the learners (80%) to experience (80%) the practical dimension of important ethical issues and to conduct a series of moral experiments within the virtual simulations. Most of the students (75%) were able to correctly relate theoretical knowledge from philosophy and ethics to specific video game situations and successfully interpreted them. Conclusion. Given the time-consuming nature of these cybertexts, it is recommended that they be used only as supplementary media to the main course texts. It seems most appropriate to study them as part of an elective to a basic course in ethics or philosophy. This material could also be the basis for the creation of an educational laboratory on practical ethics in a social and humanitarian quantorium.

Athletic Trainer Emergency Management Skill Assessment via Low Fidelity Simulation Authors

Introduction: Athletic training education requires the inclusion of emergency management (EM) best practices, however the Board of Certification (BOC) does not mandate any continuing education (CE) past Emergency Cardiac Care (ECC). With EM best practices continuing to change there is potential for a large knowledge gap to develop in practicing athletic trainers (ATs) who do not chose to engage in EM CE. The purpose of this study was to identify knowledge gaps in practicing ATs’ EM skills via low fidelity simulation. Methods: A cross-sectional study was conducted in an educational laboratory setting involving twenty-two ATs (age 36.7±10.8 years; 13 males, 9 females, years of experience 13 + 11) attending a simulation-based CE event. A convenience sample of participants who attended the CE event voluntarily participated in data collection. Upon the completion of an educational review session, participants completed four low fidelity simulations (elbow dislocation, femur fracture, heat stroke and external hemorrhage) based on the 2020 Commission on Accreditation of Athletic Training Education (CAATE) standards. Checklists (completed/not completed) were utilized to grade participants simulation specific skill application. Mean overall, critical action, SAMPLE and vital scores were analyzed. Scores were calculated as percentages in order to compare the low fidelity simulation outcomes. A benchmark of 80% skill application was utilized for a successful pass rate. Results: The only benchmark achieved was the critical action score within the femur fracture simulation (82.89% ±14.56). A success rate of 9.6% (8/83) was calculated across all simulations. The mean total percent scores were as follows; elbow dislocation 65.0 ± 11.0, femur fracture 55.3 ±10.0, heatstroke 67.7 ±17.5 and external hemorrhage 64.0 ±13.0. All means beyond the critical action femur, were below the benchmark of 80%. Conclusions: A knowledge gap exists between practicing clinicians and the 2020 CAATE EM standards. Considering the importance of ATs lifesaving skills, ATs should aim to choose CE to improve their EM skills. While this study only investigates EM, ATs may demonstrate knowledge gaps in other domains and therefore ATs should aim to diversify their CE to stay current with best practices.

Numerical Investigation of the Indoor Environmental Factors With Stratum and Underfloor Air Distribution Systems in an Educational Institute Computer Laboratory

Abstract Ventilation with optimal airflow patterns is the most significant aspect in controlling airborne transmission as well as providing an improved indoor thermal environment and air quality in an energy-efficient way. Conducting the air-conditioned computer laboratory in educational institutes during the pandemic is challenging. This article presents a comparative study on various aspects related to indoor environmental quality factors, including thermal comfort indices, vertical air temperature differences, draught rate, air distribution effectiveness, CO2 concentration levels, energy saving, and dispersion of exhaled droplets of aerosols in different sizes (0.5 μm, 6 μm, 20 μm, and 45 μm). The study examines these factors by comparing 12 cases with different air distribution strategies (stratum, underfloor), air change rates (15 ACH and 20 ACH), and return outlet positions (1.3 m, 1.8 m, and 2.3 m). The numerical investigation is carried out in the educational institute computer laboratory model with the dimensions of 10 m (length), 5 m (width), and 3 m (height). The findings indicated that stratum ventilation and underfloor air distribution (UFAD) at a rate of 20 ACH, along with the placement of the return outlet in position 2, would ensure adequate ventilation, acceptable thermal comfort, and optimal energy savings. Compared to the overhead air distribution system, the maximum energy savings were obtained at 10.15% and 10.07% in both stratum and underfloor air distribution systems. Furthermore, the higher air distribution index and ventilation parameter were acquired in the UFAD system at 20 ACH. This study provides a better understanding of air distribution systems and aerosol particle dispersion in the indoor environment of a computer laboratory.

Peering into the team role kaleidoscope: the interplay of personal characteristics and verbal interactions in collaborative problem solving.

The objective of this study is to explore the relationship between personality and peer-rated team role behavior on the one hand and team role behavior and verbal behavior on the other hand. To achieve this, different data types were collected in fifteen professional teams of four members (N = 60) from various private and public organizations in Flanders, Belgium. Participants' personalities were assessed using a workplace-contextualized personality questionnaire based on the Big Five, including domains and facets. Typical team role behavior was assessed by the team members using the Team Role Experience and Orientation peer rating system. Verbal interactions of nine of the teams (n = 36) were recorded in an educational lab setting, where participants performed several collaborative problem-solving tasks as part of a training. To process these audio data, a coding scheme for collaborative problem solving and linguistic inquiry and word count were used. We identified robust links and logical correlation patterns between personality traits and typical team role behaviors, complementing prior research that only focused on self-reported team behavior. For instance, a relatively strong correlation was found between Altruism and the Team builder role. Next, the study reveals that role taking within teams is associated with specific verbal interaction patterns. For example, members identified as Organizers were more engaged in responding to others' ideas and monitoring execution.

EduSolar: A Remote-Controlled Photovoltaic/Thermal Educational Lab with Integrated Daylight Simulation

This study presents a compact educational photovoltaic/thermal (PV/T) system designed for thorough performance assessment under simulated weather conditions. As an affordable educational tool, the system offers significant pedagogical value. The PV/T system features two photovoltaic modules: a thermally enhanced module and a standard one. The thermally enhanced module uses water as a coolant, which transfers heat from the PV cells to a fan-operated heat exchanger, with the coolant being recirculated to maintain optimal conditions. A halogen lamp, placed between the modules, simulates solar radiation to ensure effective electrical current generation. The system’s remote-control capabilities, managed via the Message Queuing Telemetry Transport (MQTT) protocol, enable real-time adjustments to the coolant flow rate, heat exchanger efficiency, and lamp brightness, as well as monitoring of electrical parameters. Experimental findings indicate that the PV/T module achieves a 7.71% increase in power output compared to the standard PV module and offers a 17.41% improvement in cooling efficiency over scenarios without cooling. Additionally, the numerical methods used in the study show a maximum deviation of 4.29% from the experimental results, which is considered acceptable. This study showcases a best practice model for solar training, applicable from elementary to university levels, and suggests innovative approaches to enhancing solar energy education.

Water recycling in teaching laboratories for civil construction courses

Civil construction courses have laboratories for the development of educational activities. The activities involve the production of construction elements that require the consumption of treated water to prepare materials and wash equipment, generating liquid effluents at the end of each class. The reuse of liquid effluents generated in the civil construction educational laboratory was studied with the aim of reducing the demand for treated water and reducing the liquid waste discharged into the public sewage system. The effluent generated was collected, quantified and treated by primary decantation, generating reused water. Concrete was produced with reused water as a replacement for treated water, with contents of 20, 50, 80 and 100% and compared to the control concrete, 100% treated water. Parameters of axial compression strength and durability by natural carbonation were evaluated. Concretes with up to 50% reused water presented the same carbonation as the control concrete, and concretes produced with 80 and 100% reused water presented carbonation (2.5 mm), a result slightly higher than the carbonation of concretes produced with up to 50% reused water (1.5 mm). Considering the test results, it can be concluded that it is possible to reuse up to 50% of the reused water in the production of concrete without compromising mechanical resistance and durability. For educational purposes, it is possible to use 100% of the reused water produced, that is, pure, contributing to sustainability and with the guarantee that such use does not cause any harm to the health of teachers, technicians or students. It should also be considered that such use becomes efficient and can be an alternative to treating the waste and its subsequent release into the public network or directly into nature.

Experiential Learning Labs for the Post-COVID-19 Pandemic Era

The post-pandemic era shaped by COVID-19 has compelled universities to reimagine their learning experiences, adapting to new educational requirements and heightened expectations. However, this transformation brings forth novel pedagogical requirements and learning limitations. In today’s educational landscape, learners seek active and relevant learning experiences that seamlessly integrate interactivity, crisis awareness, and global challenges tied to a resilience and sustainability perspective. To address this imperative, our work introduces an experiential learning lab to articulate Kolb’s experiential learning cycle and authentic assessment principles. By incorporating real-world events as study scenarios, higher-order skill challenges, and self-regulated learning in alignment with reflective and practical activities, we aim to enhance students’ engagement and learning relevance. To illustrate practical implementation, we propose a case study methodology regarding an experiential learning lab for operations management education. Specifically, we delve into a case study centred around the Social Lab for Sustainable Logistics, involving a circular economy challenge as a learning experience during the post-COVID-19 pandemic. Preliminary results indicate that the experiential learning lab helped to create the learning experience in alignment with intended learning outcomes. However, further instances of such learning experiences are necessary to explore the contribution and applicability of the lab across diverse settings and disciplines.
