Traditional Classroom Teaching

Background: Rapid advancement in technology has provided alternatives to traditional classroom teaching. Such instructional methods have gained increasing importance during the COVID-19 pandemic when physical classroom attendance was not possible. The study evaluated faculty’s and students’ perceptions concerning the online virtual classes and recorded lectures as compared to traditional classes delivered at the College of Dentistry, King Saud bin Abdulaziz University for Health Sciences. Materials and Methods: Surveys were developed and distributed to 34 faculty members and 186 students. Perceptions about virtual classes, recorded lectures, physical attendance, the effectiveness of different teaching methods, and overall experience were evaluated. Descriptive statistics were presented using frequencies and percentages. The Chi-square test compared the students’ and the faculty members’ responses. The level of significance was set at α =0.05. Results: Thirty-one faculty members and 149 dental students participated, and the overall response rates were 91.2% and 80.1%, respectively. While there was a general agreement on the usefulness of making recorded lectures available, a statistically significant difference (p<0.001) was found between students’ and faculty members’ views on making classroom-lecture attendance optional (67.1% of students and 12.9% of the faculty agreed/strongly agreed). Statistically significant differences (p<0.001) were found between the students and faculty members concerning the effectiveness of recorded lectures and attending online virtual classes as an alternative to classroom attendance. Conclusion: Overall, students were more accepting of technology than faculty members as a substitute for traditional classroom teaching. For a more efficient and satisfactory learning experience, both teaching methods should be considered in a blended-learning module.

SUMMARY Objective: The purpose of this study was to evaluate the effectiveness of five different polishing systems on a computer-aided design and computer-aided manufacturing (CAD/CAM) polymer-infiltrated ceramic-network restoration with nanoscale assessment using atomic force microscopy (AFM) and visual assessment performed by dental school senior students and faculty members. Method: Forty-eight full coverage crowns were milled out of polymer-infiltrated ceramic-network CAD/CAM blocks (Vita Enamic) for polishing with one company proprietary, two ceramic and two composite polishing systems. The prepared crowns were divided into six groups: (1) no polishing (control); (2) polishing with Vita Enamic Polishing Kit (VEna); (3) polishing with Shofu Porcelain Laminate Polishing Kit (SCer); (4) polishing with Brasseler Dialite Feather lite All- Ceramic Adjusting & Polishing System (BCer); (5) polishing with Shofu Composite Polishing Kit (SCom); and (6) polishing with Brasseler Composite Polishing Kit (BCom). The polished crown surface topography was observed, and surface roughness and area were measured with AFM. In addition, polished crowns were visually assessed by 15 senior dental students and 15 dental school faculty members. Results: All polishing treatments significantly reduced the surface roughness and area of the crown compared with the control. SCom and BCom showed significantly higher surface area than VEna, and the SCer and BCer groups were intermediate, showing no significant difference from either VEna or SCom and BCom. There were no significant differences in surface roughness between any of the systems. Dental students and faculty members classified the groups polished with VEna, SCer, and BCer groups as clinically acceptable, and they selected BCer group as the best polished restorations and the control group as the least polished restorations. Conclusions: Ceramic and composite polishing systems produced similar polishing results as that observed using a company proprietary polishing system. However, effectiveness for polishing using a company proprietary and ceramic polishing system tends to be higher than composite polishing systems.

Webster's Ninth New Collegiate Dictionary states that education involves learning and then defines learning as the acquisition of knowledge or understanding through study, instruction, or experience.1 This is the best and broadest definition of the term I know of and the one that most closely informs what I do in my work as director of the Cushing Memorial Library and Archives at Texas A&M University. I consider any activity that provides opportunities for study or experience as education. In a special collections environment, this includes traditional classroom teaching as well as many other undertakings—exhibits, displays, guided and self-guided tours, . . .

Perception Survey

The aim of this study was to analyze the self-perceived general health, oral care, stress, academic environment, and harmful habits of Mexican dental students during the COVID-19 quarantine period.  This descriptive observational study consisted of a self-perception survey that was sent to dental students undergoing virtual classes. Five sections were analyzed: General Health, Oral Health, Stress, Academic Environment and Habits. For each question, students were asked to rate their perception prior to, and during the contingency, which allowed a comparison to be made between both times for each inquiry. The answers were collected into Microsoft Excel and the statistical analyses were performed using SPSS v.20. A statistically significant difference was observed between the academic years for the variables: “physical exercise” prior to quarantine, “emotional problems” and “work-load” during quarantine, and “academic efficiency” for both times. A trend towards unfavorable perception in relation to general health, academic environment, and harmful habits was observed among dental students during social isolation derived from the pandemic. It is notable that 1st-year students presented a greater impact on all the variables of interest.

Abstract. With the continuous improvement of education informatization level, especially the rise of MOOC, online and offline hybrid teaching, which organically combines traditional classroom teaching with network teaching, is endowed with more abundant connotation. The outbreak of the COVID-19 in 2020 also makes colleges and universities pay more attention to the important role of the network education platform in teaching. How to carry out the mixed teaching scientifically is becoming a new topic. In this paper, the hybrid teaching is applied to the teaching of computer network course, which can not only stimulate students' interest in learning, but also mobilize students' learning initiative and improve their learning effect.

Cardiovascular Simulator

Understanding cardiovascular physiology, pharmacology, and treatment of shock is heavily emphasized in current medical school and surgical training. Performance of individuals in treatment of critical illness remains poor despite regular didactic sessions. We have developed a PC computer-based simulator capable of integrating basic hemodynamic parameters to dynamically generate a realistic patient monitor. The methodology includes physiological feedback as found in humans. The trainees are able to learn through a series of scenarios or ad lib manipulation of parameters. Participants including medical students, nurses, and residents were given a pretest before attending either a 30-minute didactic or a 10- or 30-minute simulator session. A posttest was administered to evaluate performance after the intervention. Twenty-four participants were equally randomized with 12 receiving simulator training. Although the two groups had similar pretest scores ( P > 0.5), the simulator group showed a 24 per cent improvement, whereas the lecture group showed a 10 per cent improvement in the posttest score ( P = 0.008). Simulations in surgery and critical care are in early stages of development. Access to such simulators on a personal computer can greatly enhance understanding of the cardiovascular system. These simulators appear to be very effective and may become an integral adjunct to traditional classroom teaching methods.
