ABSTRACT
Due to the COVID-19 pandemic, university teaching had to be kept up in spite of severe contact restrictions. Virtual teaching of animal nutrition was implemented at the Veterinary Faculty of the Ludwig-Maximilians-Universität (LMU) München, Germany, for both lectures and practical courses. Live online classes were held via Zoom®, and recordings were accessible afterwards. Animal nutrition is taught in the 5th and 6th term of the veterinary studies, followed by an oral state exam about subjects from both terms. In this study, the success of classroom vs. virtual teaching in veterinary animal nutrition was evaluated by comparison of exam results. Two exam cohorts (2019, before the pandemic;2020, with one term of virtual teaching during the pandemic) were evaluated. The results indicated no significant difference of teaching method on the grades. However, there was a significantly higher probability of students not taking or failing the exam in the 2020 exam cohort, suggesting a general effect of the pandemic on the students. Additionally, two surveys were distributed among the students during summer term 2020 and winter term 2020/21, when virtual teaching due to the pandemic had been implemented for the first time. The survey results provide insights into the students' view of benefits and problems of virtual teaching in animal nutrition at the LMU. The majority was in favor of the live online format for lectures and courses in computed-based ration calculation, whilst feedstuff demonstrations were preferred in classroom setting.

ABSTRACT
Previous lectures targeted at overseas Chinese children have mostly been offline in the form of youth camps sponsored by the Chinese governments before the COVID-19 pandemic and are now usually administered online in a single-topic format trans-nationally post-pandemic. This form of "one-to-many” singular online lectures comes along with discontinuity, mass audiences, chaos, and being less tailored to the individual needs and context, failing to meet the evaluation metrics in different evaluation levels. This paper proposes a model of transnational online livestreaming serial socio-cultural lectures for overseas Chinese children, which puts forward the synergy of lecturing staff from higher educational institutions (HEIs) in China and students at Chinese language schools (CLSs) worldwide as participants. Lecturing staff from needs and context HEIs can guarantee sufficient keynote speakers for "one-on-one” mode and cope with the above-mentioned problems. After the implementation of five sessions of these serial lectures, evaluation of this model shows that the pre-lecture, during-lecture, and post-lecture stages have are applicable. Furthermore, for sociocultural lectures, the audience may be more interested in literature classics than folk arts from a specific region. Correlation analysis reveals that younger children have a better evaluation of this model and an improved inclination to attend lectures, which sheds light on the improvement of sociocultural lectures as online lectures are preferred among overseas Chinese children. © ZHILING YANG, 2023.
ABSTRACT
Online classes quickly became a hot topic in education during the effort to prevent and manage the COVID-19 outbreak. This paper is of great value in analyzing the factors influencing online delivery from a socially acceptable perspective, using the online DingTalk platform course as the research target. The researchers of this paper used a questionnaire to establish the conceptual basis of the survey based on the technology acceptance model (TAM), and developed the corresponding survey questions. The questionnaire was distributed to 528 respondents, of which 495 were valid data samples;furthermore, the sample efficiency of the returned questionnaire was 93.75%. The data were analyzed by SPSSAU software for reliability (Cronbach alpha: 0.967). For the purposes of assessing validity, ANOVA was used, and the SEM structural ANOVA was utilized in order to understand the impact of using the DingTalk platform for online classroom teaching, as well as to study user satisfaction with its use and to make relevant suggestions for continuing to use the online platform for classes in terms of campus management for online/offline hybrid teaching.
ABSTRACT
The purpose of the present study is to examine the students' opinion regarding the conducted online educa-tion. Sociological methods: an anonymous Google forms survey was conducted including dental medicine students studying in the conditions of the COVID-19 pandemic, which led to the need to switch to an online form of education. It was conducted online on a voluntary basis in the month of March 2021. A total of 50 students from various years, studying Dental Medicine at the Medical University of Varna took part in the study. The provided survey consists of 20 questions. The majority of students categorically state that face-to-face study is preferable and that digital learning methods are motivating for them. Almost half of the students have a positive opinion regarding online lectures. Through them, they get more advice and guidance from the teachers and it is easier to participate in discussions. The participants in the survey shared that online training, as a result of the introduced anti-epidemic measures, was a good option for learning the the-oretical study material.Copyright © 2022, Bulgarian-American Center.

ABSTRACT
Since COVID-19, social distancing has become common, and the demand for untact services has increased rapidly, resulting in an economic phenomenon centered on untact worldwide. Due to social distancing, the untact service area is expanding not only to shopping but also to online learning, home training, and telemedicine, and untact services are expected to expand to more diverse areas in the future. This study investigates four types of untact services: online lectures, online meetings related to work and study, online seminars, and online performances, and the effects of concerns about untact services on the intention of use have been examined using a path analysis model. As a result of the analysis, the perceived usefulness had a positive effect on the user's continuous intention to use untact services. However, depending on the type of untact service, it can be confirmed that the factors that affect the intention to continue using the service differ from each other. Practitioners can use the results of this study when designing untact services in the future. © 2023 by the authors.
ABSTRACT
In recent years, COVID-19 policy measures massively affected university teaching. Seeking an effective and viable way to transform their lecture material into asynchronous online settings, many lecturers relied on prerecorded video lectures. Whereas researchers in fact recommend implementing prompts to ensure students process those video lectures sufficiently, open questions about the types of prompts and role of students' engagement remain. We thus conducted an online field experiment with teacher students at a German university (N = 124; 73 female, 49 male). According to the randomly assigned experimental conditions, the online video lecture on topic Cognitive Apprenticeship was supplemented by (A) notes prompts (n = 31), (B) principle-based self-explanation prompts (n = 36), (C) elaboration-based self-explanation prompts (n = 29), and (D) both principle- and elaboration-based self-explanation prompts (n = 28). We found that the lecture fostered learning outcomes about its content regardless of the type of prompt. The type of prompt did induce different types of self-explanations, but had no significant effect on learning outcomes. What indeed positively and significantly affected learning outcomes were the students' self-explanation quality and their persistence (i.e., actual participation in a delayed posttest). Finally, the self-reported number of perceived interruptions negatively affected learning outcomes. Our findings thus provide ecologically valid empirical support for how fruitful it is for students to engage themselves in self-explaining and to avoid interruptions when learning from asynchronous online video lectures.
ABSTRACT
BACKGROUND: Basic life support (BLS) education is essential for improving bystander cardiopulmonary resuscitation (CPR) rates, but the imparting of such education faces obstacles during the outbreak of emerging infectious diseases, such as COVID-19. When face-to-face teaching is limited, distance learning-blended learning (BL) or an online-only model-is encouraged. However, evidence regarding the effect of online-only CPR training is scarce, and comparative studies on classroom-based BL (CBL) are lacking. While other strategies have recommended self-directed learning and deliberate practice to enhance CPR education, no previous studies have incorporated all of these instructional methods into a BLS course. OBJECTIVE: This study aimed to demonstrate a novel BLS training model-remote practice BL (RBL)-and compare its educational outcomes with those of the conventional CBL model. METHODS: A static-group comparison study was conducted. It included RBL and CBL courses that shared the same paradigm, comprising online lectures, a deliberate practice session with Little Anne quality CPR (QCPR) manikin feedback, and a final assessment session. In the main intervention, the RBL group was required to perform distant self-directed deliberate practice and complete the final assessment via an online video conference. Manikin-rated CPR scores were measured as the primary outcome; the number of retakes of the final examination was the secondary outcome. RESULTS: A total of 52 and 104 participants from the RBL and CBL groups, respectively, were eligible for data analysis. A comparison of the 2 groups revealed that there were more women in the RBL group than the CBL group (36/52, 69.2% vs 51/104, 49%, respectively; P=.02). After adjustment, there were no significant differences in scores for QCPR release (96.9 vs 96.4, respectively; P=.61), QCPR depth (99.2 vs 99.5, respectively; P=.27), or QCPR rate (94.9 vs 95.5, respectively; P=.83). The RBL group spent more days practicing before the final assessment (12.4 vs 8.9 days, respectively; P<.001) and also had a higher number of retakes (1.4 vs 1.1 times, respectively; P<.001). CONCLUSIONS: We developed a remote practice BL-based method for online-only distant BLS CPR training. In terms of CPR performance, using remote self-directed deliberate practice was not inferior to the conventional classroom-based instructor-led method, although it tended to take more time to achieve the same effect. TRIAL REGISTRATION: Not applicable.

BACKGROUND: The flipped classroom (FC) is a well-known active learning module that activates the prior knowledge of students and promotes their cognitive skills during in-class activities. However, most on-site teaching during the COVID-19 pandemic had to be conducted online. The FC in our rehabilitation medicine clerkship curriculum was also shifted to online asynchronous lectures (OLs), without real-time interactions. There is no previous comparison of effectiveness between these two methods. Therefore, this study aimed to compare learning outcomes and student satisfaction in both FC and OL models. METHODS: The study design was a historically controlled study. A physical modality was chosen for the content. The FC group (n = 233), in the academic years 2018 and 2019, was assigned to perform a pre-class activity consisting of reading study materials. Thereafter, the in-class activity comprised a small-group case-based discussion. The OL group (n = 240) in the academic years 2020 and 2021 followed an online model during the COVID-19 lockdown. They were also asked to read the online materials and then watch a self-paced recorded lecture video on Learning Management Systems. The learning outcomes, including their multiple-choice questions (MCQs) scores, final exam scores, grade points, and letter grades, were evaluated. Their overall course satisfaction ratings were also collected. RESULTS: The OL group had an overall higher MCQ score for the physical modality portion than the FC group (p = 0.047). The median (lower quartile, upper quartile) of the total 50-MCQ scores were 34 (31, 37) in the OL group and 33 (29, 36) in the FC group (p = 0.007). The median final exam scores of the OL and FC groups were 69.5 and 68.3, respectively (p = 0.026). The median grade points and the letter grades were not significantly different between the groups. The proportions of satisfaction were significantly higher in the FC group than in the OL group. CONCLUSIONS: The OL group revealed significantly higher learning outcomes than the FC group. However, the FC group showed more satisfaction with interactivity than the OL group. The authors are of the view that a combination of both FC and OL methods will likely result in better outcomes.

This case study looks at implications of transitioning live to recorded lectures, a subject that has acquired an acute importance given COVID19 and the unexpected need to move lectures online. Over a period of six years, from 2015 to 2020, a questionnaire was handed out at the end of a 'unit' on environmental geoscience;a 'unit' at Australian universities represents a 'course' in the European and American tertiary system. This is a 2nd semester, 3rd year core unit of an Applied Geology course meaning that (most of) the polled students were about to acquire a bachelor of science finishing their undergraduate studies. The students were asked multiple questions related to iLectures and their attitude towards this asynchronous content delivery approach as integral part of a flipped classroom. Provided that such a STEM unit with 40-120 students can be deemed representative of the wider student community, the findings indicate that students in general have come to terms with online lectures, way before COVID19 gave them no other choice. Acceptance rates for iLectures were over 50 % across all years, except for 2020, a clear indication that COVID19 marred the online experience, probably due to oversaturation and isolation. The majority of the students saw benefits in this asynchronous lecturing approach, irrespective of whether the rationale behind it had been explained in detail. Despite seeing benefits of the flipped classroom and recorded lectures, one out of three students preferred live lectures. This number has increased after COVID19 to 40 %, yet another sign of the negative impact of the pandemic on online lecturing. This inference is unrelated to the quality of the recordings which was deemed high. Finally, the importance of meaningful extended lecture notes to complement the recordings is highlighted.
ABSTRACT
The purpose of this study is to evaluate various online resources available for radiology education. An online search was conducted using PubMed (National Library of Medicine, Bethesda, MD) and Google Scholar for publications discussing the applications of online learning in radiology. The search strategy employed a combination of the following terms: radiology, web-based conferencing, radiology education seminars, radiology education online, radiology education programs, online lectures, radiology residency, radiology degree, Radiology-Integrated Training Initiative (R-ITI) e-learning platform, UTAUT, Moodle, active image-based learning, Video conference platforms (VCPs), education, undergraduate, medical students, teaching, virtual learning, blended learning, e-learning, COVID-19, pandemic, OER, open education resources, online learning, course assets, accessibility, 5G Internet, game-based learning, radiology competition, and virtual world. The literature published was reviewed and consolidated. Data from the literature shows that radiology education online and radiology education seminars are undergoing a revolution due to advancements in computers, online software, and 5G Internet speed. The pace of this development has accelerated even further due to the COVID-19 pandemic and thus forced distance online education. Various technologies are available and are being implemented by residency programs across the world to improve radiology education, making it more interactive and safer in this pandemic. Online learning has become an integral part of education in radiology, with new facets being added to it.
ABSTRACT
The lecture has been around for centuries and has featured as a popular and frequent component in higher education courses across many disciplines including anatomy. In more recent years, there has been a growing shift toward blended learning and related pedagogies that encourage active participation of students in both face-to-face and online learning environments. Unfortunately, in many cases, the lecture, which has typically focused on the transmission of information from educator to student has not been adapted to become a more learner-oriented approach with opportunities for students to actively interact and engage. As a result, the future of whether the lecture should continue has once again become a center of debate. The consequence of the Covid-19 pandemic and its aftermath have added to this with institutions now looking to stop all lectures or offer them in an online format only. This commentary argues that lecture-style components could still feature within face-to-face and online provision, but only if they are used sparingly within a blended curriculum, have a defined use that aligns well to learning outcomes, are assessed as the most effective method pedagogically, and importantly integrate approaches and activities that promote student engagement. Anatomy educators have demonstrated for years that they are able to be at the forefront of pedagogical change and evidenced during the pandemic their agile and innovative ability to adapt and do things differently. Therefore, the fate of the lecture, at least in anatomy, may well be in their hands.

The number of online lectures has increased against the backdrop of the COVID-19 pandemic. With the increase in online lectures, more methods of evaluating their quality and improving lecture styles are being developed. We proposed a method of estimating online lecture quality using the SD-F0 values of students’ response utterances. First, we confirmed the effectiveness of the SD-F0 values of students’ response utterances in estimating students’ understanding of lectures. Through identification experiments using an online lecture video database, the precision rate of “Understanding” was found to be 80.6%. This suggests that when the SD-F0 value was high, with a high probability, the student understood the lecture content. Next, we analyzed the relationship between the SD-F0 values of the students’ utterances and lecture quality. We confirmed that during the first thirty minutes of a lecture, when the SD-F0 value was high, the lecture was considered high-quality. If the SD-F0 values of the 10% or 20% utterances in a lecture exceeded a boundary set by the SVM (the boundary between high- and low-quality lectures), the lecture could be regarded as high-quality. The identification rate was greater than 80%. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
This study analyzed the impacts of the COVID-19 pandemic on higher education in Japan by conducting a student opinion survey on Zoom lectures. After the COVID-19 pandemic hit Japan, almost all universities in Japan shifted their conventional face-to-face lectures to online lectures, including Zoom lectures. Prior to the COVID-19 pandemic, only a limited number of universities provided online lectures. As a result, neither professors nor students were familiar with online lectures at the university level. However, the COVID-19 pandemic required university professors to launch online lectures without enough time for preparation;similarly, students were also required to receive online lectures without enough preparation. This study's results provide suggestions and recommendations for both universities and students to improve online lectures at universities during and after the COVID-19 era.
ABSTRACT
The use of online video conferencing has skyrocketed due to the ongoing outbreak of COVID-19. Not only professionals and college students, but even the elders and preschoolers use video meeting programs. As such, and due to a variety of reasons such as lack of context or audio-incapable circumstances, the need for high quality closed-caption has also risen. Speech-to-Text (STT) technology has been leaping forward significantly, yet involving the defect of the somewhat low recognition rate of jargons and professional terminology, which can lead to critical misunderstandings for lectures or meetings dealing with field-specific contents. To address this issue, we propose an enhancement to the recognition of technical terms by introducing Contents-aware-captioning (CAC) algorithm which applies automatically extracted data from previous materials of the wehinar or terminology dataset according to the subject.
ABSTRACT
The purpose is to describe the perception of first-year students towards online lectures during the pandemic viewed from learning motivation. The research method used descriptive qualitative with a case study approach. This study’s subjects consisted of 165 first-year students with heterogeneous backgrounds. The sampling technique employed was the purposive sampling technique. The collecting data, technique of questionnaire, observation, and interviews were carried out online. Data analysis technique was then utilized, covering the stages of data validity, data collection, data reduction, data presentation, and drawing conclusions. The results revealed students’ perceptions of online lectures that (1) the preferred type of communication was semi-two-way, (2) the preferred type of media was SPADA, Google Meet, and WhatsApp, and (3) the preferred type of lecture material was modules, learning videos, and video conferencing. In addition, (4) there was a positive perception of lecturer skills, primarily regarding lecture interactions, and (5) more than 50% of students were satisfied with online lectures. Viewed from learning motivation, student perceptions uncovered that (1) learning motivation did not affect student perceptions of online lectures, and (2) there were findings of factors influencing student perception of online lectures, namely, internal factors in the form of study habits, physical and mental health, and external factors in the form of a learning environment. This study concludes that students had a positive perception of online lectures, and several factors affected the student’s perception of online lectures. © 2022
ABSTRACT
COVID-19 has changed our daily lives dramatically;temporary lectures moved online to address the pandemic are now no longer temporary but a common occurrence. In Japan, COVID-19 cases have fluctuated repeatedly and a state of emergency has been declared over and over again. No one knows when we will return to pre-pandemic life. In this prolonged situation, social life is gradually changing to a lifestyle with COVID-19. University life has also been changed. This paper reports online lectures in our university and their changes and now. © 2022 ACM.
ABSTRACT
BACKGROUND: The COVID-19 pandemic has caused an unprecedented disruption in medical education. Students and lecturers had to adapt to online education. The current study aimed to investigate the level of satisfaction and future preference for online lectures among clinical clerkship students and elucidated the factors that affect these outcomes. METHODS: We selected a sample of 114 medical students undergoing clinical clerkship during the COVID-19 pandemic. We conducted onsite lectures before the pandemic and online lectures after the outbreak. A survey was conducted, and the sample included students and 17 lecturers. The average scores of total satisfaction and future preference related to online lectures were computed. RESULTS: Students' scores on total satisfaction with online lectures and their future preference were higher than those for onsite lectures. Scores on the ease of debating dimension were low and those on accessibility of lectures in online lectures were higher than those in onsite lectures. There was no difference between the two groups in the scores on the comprehensibility and ease of asking questions dimensions. Results of the multiple regression analysis revealed that accessibility determined total satisfaction, and future preference was determined by comprehensibility as well as accessibility. Contrary to students' future preferences, lecturers favored onsite lectures to online ones. CONCLUSION: Online lectures are an acceptable mode of teaching during the COVID-19 pandemic for students undergoing clinical clerkship. Online lectures are expected to become more pervasive to avoid the spread of COVID-19.

The Covid‐19 pandemic has forced institutions of higher education to create digital learning environments replacing physical classrooms. The transition to digital teaching has been both abrupt and challenging for many lecturers and students. While communication and interaction between lecturer and student or among students are possible digitally, there is a difference between sitting physically next to your fellow students versus staring into a “black screen”. This paper investigates experiences of online learning among students in higher education during lockdown. We conducted an online survey (n=200) among students in Norway studying for a bachelor’s degree in information technology (IT). We emphasize students’ experience of the digital learning environment through questions on attendance and participation in live lectures, use of recorded videos, use of chat and camera and their motivation for digital learning. The findings show that students to a large or very large extent (85%) follow live lectures, at the same time they also prefer that there are video recordings of the lectures. Furthermore, we see that the students are highly or very highly (65%) motivated for digital live lectures. Concerning student engagement, such as asking questions to the lecturer and answering questions from the lecturer in the Zoom‐chat, we see that the answers vary greatly. They are distributed almost equally on the whole scale from a very small degree to a very high degree. Among our relevant contributions, we have learned that recording lectures is overwhelmingly considered positive among students and should be practiced when possible. Students rarely if ever turn on their cameras during lectures and do not expect others to show their faces. In general, among our respondents Zoom online lectures seem to work well, despite limitations to interaction and participation. © the authors, 2021. All Rights Reserved.
ABSTRACT
The outbreak of COVID-19 has caused the canceling of in-person lectures on a massive scale. Rapid movement of education to online platforms will eventually lead to innovations in remote education. At the moment, however, instructors lack guidance. This short article describes approaches for producing video for remote and active learning.
