ABSTRACT
During the COVID-19 pandemic, people voluntarily reduced their necessary healthcare. We examined whether supplying educational digital versatile discs (DVDs) before admission can reduce parental rejection of pediatric cardiac catheterization for congenital heart disease (CHD). Parents of 70 children with CHD selected for cardiac catheterization were randomly allocated to the DVD (received pre-admission DVDs in the outpatient department; 70 parents of 35 children) or non-DVD groups (did not receive the DVDs; 70 parents of 35 children). The parents could reject the admission of their children within 7 days. Cardiac catheterization was rejected by 14 (20.0%) and 26 (37.1%) parents in the DVD and non-DVD groups, respectively (p = 0.025). Parent Perceptions of Uncertainty Scale scores were lower in the DVD (128.3 ± 8.9 points) than in the non-DVD group (134.1 ± 7.3 points; p < 0.001). Decreased uncertainty due to pre-admission DVD watching could have contributed to the increased parental willingness for cardiac catheterization. The effects of pre-admission educational DVDs were more significant among parents with a lower education, rural residence, with only one child, female child, or younger child. Offering educational DVDs to parents of children selected for cardiac catheterization for CHD may decrease the parental rejection rate of the treatment.
ABSTRACT
The implementation of video as an educational resource has become widespread in recent years, driven by highly accessible platforms such as YouTube. The objective of our research is to study the use that is being given, during the COVID-19 pandemic, to audiovisual resources in higher education and to demonstrate the satisfaction with their use by teachers and students. Also, show the existence of variables that improve said satisfaction or that have a significant impact on a greater use of educational videos informally. For this, a descriptive-inferential study based on an online survey with a total sample of 684 responses from the University of Porto is provided. The results are discussed with the most recent literature on the subject. A regular use of the video by half of the sample and a significant use of informal videos by the students is concluded, obtaining, in both groups, a positive satisfaction with their use. The variables that influence satisfaction in the implementation of videos in the formal education stand out: technological competence, economic level and disciplinary area. In addition, those that condition the use of informal videos among students: gender, economic level and disciplinary area.
ABSTRACT
The COVID-19 has made it impossible for students to have face-To-face classes in the classroom. Online education provides a practical method for learning. This article makes an online questionnaire survey in S University (n = 57), describes and analyzes the online behavior characteristics of students in S University and the attitude evaluation of online educational videos. The survey found that watching videos is the main entertainment way for college students to surf the Internet. Students watch 4.5 hours of video every day. The statistical comparison of GPA shows that students can acquire knowledge in online education just like face-To-face teaching. Further research found that the quality of video played a significant positive role in students' complete viewing of video. Therefore, improving the quality of video education will provide better learning services for students. © 2022 IEEE.
ABSTRACT
Objective: To assess the effectiveness of an online educational video in improving contact lens (CL) care knowledge and behavior. Methods: Participants completed a 47-item questionnaire on their CL hygiene knowledge and wear and care behavior. A 5-min CL educational video was shown, and participants completed a post-test. After 2 months, the same questionnaire was used to determine knowledge retention and behavioral changes. Descriptive statistics and McNemar's tests were performed. Results: The mean age of the 132 enrolled participants was 24 years, and 61% were female. The knowledge scores significantly improved after watching the educational video (p < 0.001). Two months after the intervention, the participants reported changes in their hygienic behavior (p < 0.001). Conclusions: Online video-based learning is an effective educational tool for improving the knowledge and behavior of CL care. Practice implications: Patient education via online videos is an innovative and successful strategy that raises awareness, increases patient knowledge, and encourages preventative health behavior to avoid CL-related complications.
ABSTRACT
YouTube is one of the most popular video-sharing platforms. Recently, the use of YouTube as an educational tool has increased due to the covid-19 pandemic. The quality of the educational videos is crucial in the learning process. Users' comments on educational videos can help to determine the quality of the videos. Such comments can be utilized using a natural language processing technique called Sentiment Analysis. This research proposes a model to perform sentiment analysis on YouTube Arabic educational videos using classical machine learning classifiers and deep learning models. There are six experiments were conducted on two types of datasets: imbalance and balanced datasets. In addition, three balancing techniques were utilized which are: oversampling, under-sampling, and SMOTE. The results show that the best accuracy obtained from all the experiments was 96% by the SVC, RF, and DL model using the oversampling and SOMTE techniques. The worst accuracy achieved by the ML classifiers was 74% by the KNN classifier using the under-sampling technique. Meanwhile, the worst accuracy achieved by the DL model was 89% for the manually balanced dataset using the bigram, trigram, and five-gram. Additionally, this research introduced a novel dataset based on Arabic YouTube educational videos. This model can be beneficial to many researches in data mining research area or related research areas. © 2022 IEEE.
ABSTRACT
With the rise of online teaching due to the COVID-19 pandemic situation, experimental laboratories in all STEM fields have to be fundamentally reconsidered as experimental work is an indispensable part of a student's education. Creating the necessary materials for a truly useful alternative to in-person work requires looking outside the traditional methods of teaching. This paper is meant to serve as a general framework for the development of video materials. In order to make these accessible and engaging, and therefore effective, the production quality ought to be taken into account. The focus will be set on the development of a series of videos on the phenomenological study of electrolysis of water, with a particular interest in hydrogen and oxygen production. The first part of the series is designed to be accessible to a general audience, regardless of the degree of familiarity that they have with the subject, doubling as a science popularization material. The second and third parts are dedicated to students in the fields related to renewable energies, however they may be useful to any in STEM fields. The third part will include a remote access laboratory set-up by converting the original experiment. This will involve a redesign of the experimental set-up to fit the technological upgrades. This article provides a cost-efficient workflow for adapting traditional on-site experiments to the online medium. Such materials do not have to remain a tool for e-learning, but rather, they can be used as supporting materials for future in person teaching as well. © 2021, National Defence University - Carol I Printing House.

ABSTRACT
INTRODUCTION: High blood pressure is an important worldwide health issue. Pharmacists can perform multifaceted tasks in hypertension management such as measuring blood pressure. In a time where the use of educational videos in health professions education has increased, an educational video might be an option for teaching blood pressure measurement skills to pharmacy students. This project aimed to develop an educational video tailored to pharmacy students on oscillometric blood pressure measurement in a community pharmacy setting that can be used as a self-instruction video. METHODS: The video was created with support from the university's multimedia center. The video development was roughly divided into pre-production, production, and post-production. Students' satisfaction with and perception of the video was surveyed. RESULTS: An 11-minute 33-second self-instruction video in the German language on proper oscillometric blood pressure measurement tailored for pharmacy students was created. Along with descriptive slides, the video delineates the necessary steps of blood pressure measurement in a community pharmacy setting in a role-play, to support students in communication with the patient. Results of a survey on the satisfaction and perception of the video from thirty-seven pharmacy students were included in the analysis and revealed that the video was well accepted by pharmacy students. Moreover, approximately 95% responded that instructional videos should be included in future pharmacy education. CONCLUSION: We successfully developed an educational video on oscillometric blood pressure measurement for a community pharmacy setting. This work is a valuable form of support for faculty members, who intend to develop educational videos. This might be of interest especially during the coronavirus disease 2019 (COVID-19) pandemic, where distance learning has become highly relevant.
