Virtual inverted classroom to replace in-person radiology lectures at the time of the COVID-19 pandemic - a prospective evaluation and historic comparison

Background In the time of the coronavirus disease 2019 (COVID-19) pandemic, in-person lectures had to be shifted to online learning. This study aimed to evaluate students’ and lecturers’ perception and effectiveness of a virtual inverted classroom (VIC) concept on clinical radiology in comparison to a historic control. Methods In the winter semester 2020/21, 136 fourth year medical students who completed the clinical radiology VIC during the pandemic, were included in the single centre, prospective study. Results were compared with a historic control that had finished the physical inverted classroom (PIC) in the immediately preceding year. The VIC consisted of an initial phase of self-determined preparation with learning videos and a second interactive phase of clinical case studies alternating between the virtual lecture hall and virtual buzz groups. At the end of the lecture series, students rated the lecture on a scale of 1 (most positive assessment) to 6 (most negative assessment) through an online survey platform. Additionally, they reported their impressions in free-form text. Lecturers were invited to comment on the VIC in a group interview. Main outcomes were final grades and student perception of the VIC. Results Students’ general impression of VIC was lower than that of PIC (median value of 3 [IQR 4, 2] and 1 [IQR 0, 0], p < 0.001), respectively, p < 0.001). The highest rating was achieved concerning use of the audience response system (median 1 [IQR 1, 0]), and the lowest concerning the buzz groups (median 4 [IQR 5, 3]). Students stated that they would have appreciated more details on reading images, greater focus on plenary case studies, and provision of exam related scripts. Lecturers would have liked better preparation by students, more activity of students, and stronger assistance for group support. Exam grades after VIC were better than after PIC (median 1 [IQR 2, 1] and 2 [IQR 2,1], respectively, p < 0.001). Conclusions Students’ overall perception of VIC was satisfactory, although worse than PIC. Final grades improved compared to PIC. Provided an adapted buzz group size and support, VIC may serve as complement in medical education once the pandemic is over.

DETERMINASI KEPUASAN MAHASISWA KELAS INTERNASIONAL IIB DARMAJAYA LAMPUNG

In attracting international class students, IIB Darmajaya tries its best to give all the best to meet student satisfaction. English is an obligation for international class students in every given course, and they must graduate from that course. This study aims to determine the factors that determine the satisfaction of international class students of IIB Darmajaya and to determine what factors are the most dominant in the satisfaction of international class students. The population in this study were active students of IIB Darmajaya. The sampling method used in this study is non-probability sampling using a purposive sampling technique to obtain a sample of 100 respondents. The analytical tool used in this study is descriptive analysis. The results of the Importance Performance Analysis show the essential attributes, namely regarding students having problems, lecturers/employees can solve problems, the department always finds out what students need. Students feel safe with the final grades of lectures. In general, the student satisfaction index in the international class for the attributes tested is in the reasonably satisfying criteria.

Do proctored online University exams in Covid-19 era affect final grades respect face-to-face exams?

The Covid-19 pandemic forced universities to convert their traditional face-to-face exams to online exams with doubts as to whether student cheating or technical difficulties would affect their final grades. After taking three of these exams online, we considered comparing their grades with those of previous years on traditional exams. The average mark of the traditional exams before the pandemic was 6.95 over 10, while the average mark of the three exams carried out in the Covid-19 era is 6.64. The student's t test indicated that there are no significant differences between the two types of exams in the mean (p = 0.408), the median (p = 0.378), the range (p = 0.307), the minimum (p = 0.410) and the maximum (p = 0.072). Taking online exams did not modify the exam grades compared to previous years. There is a lot of variability in similar studies in the literature due to cheating that can be performed in online exams. A proctoring system, good question design, and limited exam time can minimize these differences.

Student Outcomes in Online Courses: When Does Class Size Matter?

This quantitative study investigated the relationship between class size and student outcomes (final grades and DFW rates) in online higher education courses offered by a large, 4 year public institution in the United States. The following class size cut-off points were used: 8-15 vs. 16 or more students, 8-30 vs. 31 or more students, 8-40 vs. 41 or more students, and 8-50 vs. 51 or more students. Course level data included average final grades and DFW rates for 391 online undergraduate courses taught during the years 2017 and 2018. Significant results suggest that students earned higher grades in STEM (Science Technology Engineering Mathematics) and upper-division courses when online courses included 30 or fewer students. This suggests that it may be beneficial to limit certain kinds of courses to 30 students or fewer, as 30 students may be a tipping point where the benefits of smaller online classes wear off.

Correlation between academic performance and absenteeism in a Production Engineering program

The academic performance of students can be impacted by several factors, among them the absenteeism (class absences) is one of the main responsible ones. In this way, this study had as objective to verify if there is any correlation between the final grades of the students and their absences in the classes during the semesters, in the courses of the Production Engineering program of University of Santa Cruz do Sul, Brazil. Based on the objectives, a descriptive research was employed, which used documentary research to perform the data collection. The data used were the absentee totals and the final grades of the students in each semester. A statistical analysis of correlation and linear regression was applied, and the result showed that there is a correlation between absenteeism and the students' academic performance. Although in some cases this correlation is not so significant, it was verified that missing classes decreases students' grades.

Mathematical Skills and the Academic Performance of Junior and Senior Electrical Engineering Students of the University of Eastern Philippines

The study was conducted to determine the mathematical skills and the academic performance of the junior and senior electrical engineering students of the University of Eastern Philippines. Descriptive-correlational method of research was used with a total enumeration of the regular students from third year to fifth year electrical engineering students. The findings revealed that male students dominated all the three year levels of the electrical engineering course. It was also found out that there were more regular fifth year engineering students than the third year and fourth year students. Meanwhile, the third year students got the highest average rating in the final grades of first year and second year mathematics and the lowest average rating belonged to the fifth year students. The learning style of the three-year levels was found to be visual while in terms of study habits, the third year students have very good study habit. It was also found out that the level of mathematical skills of the three-year levels were low, but the level of academic performance of the three-year levels were found out to be good. Multiple regression analysis was used to determine the relationship of the student profile and their mathematical skills. The results showed that the average of final grades in all first-year mathematics, and the students’ year level have significant relationship with the mathematical skills of the students. Meanwhile, the profile variables found to be significantly related to academic performance were the average of final grades in first year mathematics, average of final grades in second year mathematics and study habits of the students’ respondents. Lastly, the mathematical skills had no significant relationship to the academic performance of the student-respondents.
