  • Lecture Evaluation system is an only way, so far, to evaluate the quality of lectures in our university and yet has several problems. This system does not have any effects on professors; however, it is rather used to threaten assistant professors and/or part-time/full-time lecturers. As a result, students are still dissatisfied with the unchanging lectures of professors. Generally speaking, We should consider new ideas to introduce a head teacher system or improve the lecture evaluation system to open doors wider for teachers, professors do their best to expand students' understanding by practicing the Lecture Evaluation System. In fact, it is hard to keep the objectiveness that the professors estimate the quality of professors. That is why this check list should be restricted only as a guideline among the system. After all, it is expected to bring better educational circumstances when the system functions properly to provide professors to research more.

  • Background: Medical practitioners' attitudes have a significant impact on quality of care for cancer pain patients. This study was conducted to determine if being given a lecture concerning cancer pain and its management could improve the attitudes of medical students. Materials and Methods: A comparative study was conducted in 126 fifth-year medical students. Each student completed a pretest consisting of 3 questions about attitudes toward the optimal use of analgesics and 5 questions about attitudes toward prescribing opioids. Then they were given a 1.5-hour lecture, immediately following which they completed a post-test with the same questions. Results: Analysis with either comparison between groups or by matching, the post-test showed significantly more positive attitudes (p<0.05) of the medical students in all 3 questions about optimal use of analgesics and 4 out of 5 questions about prescription of opioids. The post-test results showed significantly more negative attitudes concerning the most appropriate stage for patients with severe pain to receive maximal doses of analgesics. Conclusions: Conservative attitudes, especially concerns about addiction, have been associated with a reluctance in many physicians to prescribe opioids. This study found that cancer pain education can help to improve medical student attitudes. However, fear of addiction and tolerance was still evident so emphasis of this particular issue during a lecture is essential. Providing appropriate information by means of a lecture can improve the attitudes of medical students regarding cancer pain management. However, more information should be given to lessen fear of addiction and tolerance.

  • The purpose of this study is to explore ways to improve the quality of real-time video lectures in a non-face-to-face environment using IPA (Importance-Performance Analysis). Recently, due to the impact of COVID-19 in universities, all remote classes are being implemented, so research is needed to raise learner awareness. Accordingly, factor analysis, mean analysis, correspondence analysis, and IPA analysis were performed based on the data of 632 students who responded from March 21 to June 30, 2021 for learners of K University in Chungbuk. First, overall satisfaction was low compared to importance, and the difference in system perception was the largest. Second, the difference in learner perception of real-time video lectures through the IPA matrix showed that the system error and screen cutoff were the largest. Third, the difficulty of lecture content, task and test feedback, etc. are classified. Accordingly, the satisfaction of real-time video lectures in non-face-to-face environments is low, suggesting that school-level support for quality improvement to improve learner satisfaction in non-face-to-face environments and the role of instructors are needed to improve learners' academic achievement.

  • Purpose: This study aimed to explore methods to improve the quality recognition and satisfaction level of non-face-to-face lectures among students in the departments of dental technology and dental hygiene. Methods: This survey was conducted to assess the status and preference of non-face-to-face lectures and the level of awareness and satisfaction regarding the quality of these lectures among 179 students of dental technology and 295 students of dental hygiene. Statistical analyses were performed using frequency analysis, independent sample t-test, one-way ANOVA (post-hoc Duncan), Welch analysis (post-hoc Games-Howell), and hierarchical multiple regression analysis. Results: Factors that affected the ability to assess the quality of non-face-to-face lectures were the department, the method of non-face-to-face lectures, the most preferred method for conducting lectures, the level of awareness regarding the quality of face-to-face lecture, and satisfaction level. It has 71.5% explanatory power. Moreover, factors that influenced the satisfaction level of non-face-to-face lectures included the department, grade, the highest satisfied non-face-to-face teaching method, the most effective theoretical non-face-to-face teaching method, the most preferred teaching methods, and the ability to assess quality of face-to-face lectures. It has 46.8% explanatory power. Conclusion: Non-face-to-face classes should be designed and developed for web-based programs to improve the motivation and achievement level of the students and encourage interaction between the professors and students. Our findings suggest that educators should strive to achieve optimal educational effects by efficiently combining face-to-face and non-face-to-face lectures.

  • National competitiveness is related directly to the strength of educational competitiveness of universities. Seoul National University (SNU) has been taking efforts to improve its competitiveness in University education in variety of ways and the classroom assessment is one key example of those. The current classroom assessment system practiced at universities is being used to evaluate courses and professors in charge by the university administration or evaluation committee. The classroom assessment system is not intended to put students and professors as the subject of the evaluation. In this case, the evaluation is intended wrongfully to rank the courses and evaluate professors' achievement by assigning grades on the lectures. Instead, a proper classroom assessment system should be targeted to improve the quality of lectures by encouraging communication among professor and students in the classroom. In this study, it was intended to investigate a suitable classroom assessment system to enhance the effectiveness of education, not to rank the courses and evaluate professors' achievement. For this purpose, research has been carried out to investigate opinions of professors at SNU on the criteria of classroom assessment and to analyze the criteria of classroom assessment at other domestic universities in Korea. The inquiries for feedback on the lecture by the student in the class was analyzed. The current classroom assessment system at SNU was reviewed and an improvement plan was devised to evaluate liberal art courses of engineering and science schools at SNU. In this research, the problems in the classroom assessment system was reviewed and improvement points were searched to utilize the classroom assessment system more effectively for the improvement of lecture quality.
