Effect of an endodontic e-learning application on students' performance during their first root canal treatment on real patients: a pilot study.

BACKGROUND: E-learning has found its way into dental teaching in general and endodontic teaching in particular. The present study aimed to implement a newly developed multimedia learning application and assess its effect on students' first root canal treatment on real patients. With the COVID-19 outbreak, the application's performance was investigated during the pandemic. METHODS: A total of 138 students in the initial clinical endodontic course participated in this study. The control group (n = 49) followed the traditional curriculum, including practice on artificial teeth and face-to-face teaching events. In addition to the traditional curriculum, test group 1 (n = 54) had access to an endodontic e-learning application containing videos demonstrating artificial teeth and patient cases. With the COVID-19 outbreak, test group 2 (n = 35) had no face-to-face teaching; however, endodontic patient treatments were included. The quality of students' first root canal treatment on real patients was compared using performance and radiographic assessment items. Statistical analysis was done using Kruskal-Wallis and chi-squared tests. Test groups received a questionnaire to assess the learning application. Test group 2 also completed a COVID-19-specific survey to measure students' perceptions of how the pandemic affected their endodontic education. RESULTS: The results of endodontic treatments were significantly better for test group 1 (P < 0.001) and 2 (P < 0.001) than for the control group. Likewise, there were significantly fewer treatment errors in test group 1 (P < 0.001) and 2 (P < 0.001). No significant differences were found between test groups 1 and 2. Students of the test groups positively evaluated the e-learning application. Students of test group 2 expressed their fear of negative impacts on their course performance. CONCLUSION: The e-learning application was well-received and seemed to improve endodontic education. The results imply that the quality of education may be maintained by implementing e-learning to compensate for face-to-face teaching. As no difference was found between online and face-to-face teaching, students' and lecturers' concerns that endodontic education is suffering because of the pandemic may be eased.

One year of COVID-19 pandemic: a cross sectional study on teaching oral and maxillofacial surgery.

BACKGROUND: The pandemic has challenged educational institutions to catalyze digitalization and rapidly develop online teaching formats. The aim of the study was to evaluate the teaching offered for oral and maxillofacial surgery at our university during the pandemic and to investigate the students' perceptions of the current situation. METHODS: A 38-item questionnaire with five sections (demographic information, lectures, internships, e-learning, and pandemic-related solutions/effects) was created online. Most questions were answered on a 10-point Likert scale, with 1 indicating "fully agree/positive" and 10 indicating "totally disagree/negative." The remaining questions were either answered with yes/no, percent value, or open-ended text responses. All 3rd-5th year dental students were invited to voluntarily participate and were sent a link by email in a general mail shot. RESULTS: A total of 63.7% of the participants had no prior experience with online courses before the pandemic. The students stated that the change from face-to-face to online teaching worked very well in the last two semesters (mean = 2.73, standard deviation = 2.05). Overall, the pandemic had a rather positive influence on the acquisition of theoretical skills and a negative influence on the acquisition of practical skills (p < 0.0001). The evaluation showed that, compared to other dental clinics at our university, the department for oral and maxillofacial surgery was well prepared for the pandemic. CONCLUSION: Digitalization of oral and maxillofacial surgery teaching in dental education is possible but depends on the institution's preparatory work and technological possibilities. The students declared a high acceptance of digital learning formats and indicated an increased motivation to learn due to e-learning. The pandemic's influence on the students' education was rated ambivalent.

An Evaluation of Forced Distance Learning and Teaching Under Pandemic Conditions Using the Technology Acceptance Model.

Research: Due to the sudden outbreak of COVID-19 and the resulting pandemic situation, universities were forced to rapidly change their traditional pedagogical and didactical approach by shifting from mostly face-to-face teaching to entirely virtual and online teaching methods. Through this, a "forced" distance learning and teaching situation emerged. This study aimed at investigating the effect of these innovations on the implementation, acceptance, and use of the virtual teaching offer within the framework of the technology acceptance model (TAM). Methods: A total of 218 students and 69 lecturers of a German Medical Faculty completed online questionnaires on the acceptance, satisfaction, and usefulness of the forced distance learning (FDL) and teaching (FDT), respectively. An extended version of the TAM was used to assess the acceptance of the students and lecturers of FDL and FDT. In order to estimate the multivariate dependencies, path analysis was employed using structural equation modeling (SEM). Results: In general, students and lecturers reported being satisfied with the implementation of the FDL and FDT. Regarding the TAM model, the fit indices suggested an acceptable model fit for both groups. The model of the students revealed that the perceived usefulness had a strong predictive power on the attitude toward using and the perceived ease of use also predicted the attitude. The existing technical infrastructure as well as the general media affinity and pandemic-related worries proved to be positively associated with the perceived usefulness while data security worries and organization of online teaching predicted the perceived ease of use in students. The strong positive predictive power of the perceived usefulness for the attitude toward using was also evident in the model for the lecturers and the technical infrastructure predicted the perceived ease of use in the lecturers. Conclusion: The TAM is a suitable framework to represent the implementation, acceptance, and use of the virtual teaching offer during the special pandemic situation at the university. However, personal and structural context factors were important predictors for the perceived usefulness and the perceived ease of use in the student group. The forced situation for learning and teaching makes it more difficult to predict the actual use of virtual teaching offers solely based on attitude.

Development of a tailor-made surgical online learning platform, ensuring surgical education in times of the COVID19 pandemic.

BACKGROUND: During the worldwide COVID-19 pandemic, the quality of surgical education experiences sudden major restrictions. Students' presence in the operating theater and on wards is reduced to a bare minimum and face-to-face teaching is diminished. Aim of this study was therefore to evaluate alternative but feasible educational concepts, such as an online-only-platform for undergraduates. OBJECTIVE: A new online platform for undergraduate surgical education was implemented. A virtual curriculum for online-only education was designed. METHODS: A video-based online platform was designed. Following this, a cohort of medical students participating in a (voluntary) surgical course was randomized into a test and control group. Prior to conducting a written exam, students in the test group prepared using the video platform. Students in the control group prepared with standard surgical text books. Results of the exam were used to compare educational means. RESULTS: Students in the test group preparing through the video-based online platform reached significantly higher scores in the written exams (p = 0.0001) than students of the control group. A trend towards reduced preparation time that did not reach statistical significance was detectable in the test group (p = 0.090). Scores of "perceived workload" and "desire to become a surgeon" offered no differences between the groups. (p = 0.474 and 1.000). CONCLUSIONS: An online-only, virtual curriculum proved feasible for surgical education in undergraduates. While blended learning concepts were applied in both groups, only the test group had access to case-based videos of surgical procedures and scored significantly better in the written exams. Thus, video-based virtual education offers a realistic alternative to face-to-face teaching or conventional text books in times of restricted access to the operating theatre.
