A Systematic Review of Virtual Reality-Based Education Research Using Latent Dirichlet Allocation: Focus on Topic Modeling Technique

Using virtual reality in the context of education is becoming important since this technology enhances learners' motivation and performance with transfer of learning, problem-solving skills, educational equity, and multisensory learning. Along with the 4th Industrial Revolution and COVID-19, the attention on virtual reality has been increased again. Some studies reviewed the trends of research on virtual reality-based education, mostly focusing on specific subject matters or areas. The purpose of the study is to investigate the change of research trends in the virtual reality-based education field by implementing the topic modeling analysis based on latent Dirichlet allocation (LDA) technique with 6,755 articles published in the last 30 years (between 1992 and 2022). As a result of this study, it was revealed that the research on virtual reality-based education was clearly divided into the following four periods;1992-2011, 2012-2016, 2017-2019, and 2020-2022. The main topics for each period were suggested. Here are three major findings of this study. First, it is identified that the weight of "virtual reality for learning and teaching"has increased in recent years. Second, conversely, it is identified that the proportion of "virtual reality in medical education"has decreased relatively recently. It means it is possible to interpret that the proportion of other topics has relatively increased. Third, the topics of "virtual reality education platform"and "virtual reality-based education in rehabilitation"continue to maintain a certain weight. Limitations of this study and further research suggestions are provided based on the results of the study. © 2022 Daeseok Kim and Tami Im.

Softening Performance's Pitfalls by Integrating Context and Capacity: A Government Competitiveness Framework

This article argues that government performance is better understood and managed within a broader competitiveness framework. Government competitiveness recursively integrates performance with organizational capacity and context. We illustrate this more holistic view with recent COVID-19 examples as well as recent scholarship, including some recent PAR publications related to this topic.

Coordination, incentives, and persuasion: South korea’s comprehensive approach to covid-19 containment*

A rapid and comprehensive policy response allowed South Korea to contain an aggressive outbreak of COVID-19 without resorting to the harsh lockdown measures necessitated in other countries. However, while the general content of Korea’s response is now fairly well-known, what has received less attention is the unique governance context in which the country’s containment strategy was formulated and implemented. This article focuses on 3 administrative elements of Korea’s pandemic containment approach. First, the central government effectively coordinated the efforts of sub-national governments to ensure critical resource availability and deliver a response calibrated to the situation of each locale. Second, ongoing inter-sectoral collaboration was used to marshal non-government resources in both the biotech and medical sectors which in turn enabled core features of Korea’s policy, including a rapid acceleration of testing. Third, a timely, accessible, and technocratic communications strategy, led by public health experts and leveraging the country’s highly developed information and communications technology systems, facilitated citizen trust and ultimately voluntary compliance with public health directives. Although the Korean approach offers a number of lessons for other countries, by ignoring the specific administrative and social characteristics that are relevant to its implementation, policymakers risk overestimating its inter-contextual portability. By thoroughly contextualizing Korea’s virus containment strategy, this article seeks to minimize this risk. © 2020 by the GSPA, Seoul National University.
