| Abstract|| |
Objectives: The objectives of this study are as follows: (1) To compare video-assisted teaching versus didactic lectures using the pretest and posttest. (2) To compare the feedback on the two teaching methods using a teaching feedback form.
Materials and Methods: Two consecutive batches of 22 and 20 students, respectively, of the 3rd year medical undergraduate students posted to the department of psychiatry were included for the study. The first batch underwent video-assisted schizophrenia class and didactic lecture in bipolar disorder (BPAD). A crossover of the topics was done. The students underwent pretest and posttest for each topic using the same set of topic-specific validated multiple choice questions and also filled a prevalidated teaching feedback form for each class.
Results: Difference between pre- and post-test scores after all classes was significant, indicating effective gain of knowledge by both methods. Feedback analysis indicated that most students favored video-assisted teaching (total mean feedback score – 61.99) compared to the conventional method (total mean feedback score – 60.58). Increase in mean feedback scores indicates the students' preference.
Conclusion: Both didactic and video-assisted lectures were effective in terms of knowledge gained and students' feedback. Using video assistance as a complement to lectures and not to replace the traditional methods is the way forward.

| Introduction|| |
The Medical Council of India states that an Indian Medical Graduate should possess the ability to recognize and manage common psychological and psychiatric disorders in a primary care setting and refer appropriately. However, the time allocated in the medical undergraduate (UG) curriculum is insufficient to teach them all the nuances of psychiatry. Hence, there is a need to explore more judicious methods to teach psychiatry in the limited time frame allocated in the UG medical course. Video-assisted teaching modules may help in several ways, including showing rare cases, emphasizing salient points, cutting time wastage, and avoiding patient inconveniences in various spectrum of psychiatry.,, Using videos in UG medical teaching has been known to promote observational skills and clinical reasoning and is one of the most preferred methods of blended learning., Blended learning is defined as the combination of traditional face-to-face learning and asynchronous or synchronous e-learning., Videos not only impart knowledge but also can provide public awareness, prove to be a tool for self-study, and even be used as a modality to provide feedback. In this era of e-learning, using videos to complement traditional classroom learning is effective rather than passively reviewing e-learning material.,,
With these objectives in mind, we compared the video-assisted teaching versus didactic lectures by the pre- and post-test examination and student feedback on the two teaching methods in our study.
| Materials and Methods|| |
The objectives of this study are
- To compare video-assisted teaching versus didactic lectures using the pretest and posttest
- To compare the feedback on the two teaching methods using a teaching feedback form.
It is an interventional comparative qualitative and quantitative study.
The study was conducted in the UG psychiatry tutorial classes of Sri Devaraj Urs Medical College, Kolar, Karnataka, India. The protocol was approved by the Institutional Ethics Committee No.DMC/KLR/IEC/22/2017-18. Participants who were willing to give written informed consent were included in the study. The medical students are posted to psychiatry for 15 days of ward postings in their 2nd year, 15 days of tutorials in their 3rd year, and theory classes in their final year. For tutorials in their 3rd year of medical school, a group of 20–25 students will be posted according to their roll numbers.
Selection of participants
The participants were chosen using convenient sampling. Two consecutive batches of the 3rd year medical students who were posted to the department of psychiatry for a duration of 15 days each were taken for the study and will be referred to as “Group 1” and “Group 2”, respectively. Group 1 and Group 2 consisted of 22 and 20 students each, respectively. There were no dropouts.
The students were explained about the intended outcome and assured of confidentiality, and written informed consent was obtained before taking part in the study. Group 1 underwent video-assisted schizophrenia class and didactic lecture in bipolar disorder in two subsequent classes. A crossover was done for Group 2 so that they underwent didactic lecture on schizophrenia and video-assisted class for bipolar disorder. Both types of classes lasted for 1 h each. In the video-assisted classes, the video sessions consisted of about 20 min of the total teaching time. These videos used had real or simulated patients from Kolar manifesting symptoms of either disorder. The students of both the groups were subjected to the pretest and posttest for each topic using the same set of topic-specific validated 20 multiple choice type questions. The questions had an equal mix of recall and application-based questions. The students also filled a prevalidated specially designed feedback form of 14 items using a Likert rating for each class. These forms also allowed them to highlight on the points they liked most and those that could be improved on about these teaching sessions. Questions framed for feedback were discussed with the psychiatry faculty, and 14 questions were finalized. The content validation was done by the faculty, medical education unit members, and FAIMER fellows. It was piloted on 12 students of the same term (7th) who were not a part of this study, and the internal consistency was found to be reliable (Cronbach's alpha – 0.71).
The pre- and post-test scores and feedback within the group and between the groups were analyzed using paired and unpaired t-test, respectively.
| Results|| |
From [Figure 1], it can be noted that the knowledge gained as assessed by the pre- and post-test analysis of the multiple-choice question-based assessment showed a significant gain of knowledge after all four sessions. The knowledge gained was slightly more in both the video-assisted classes undergone by Group 1 and 2 as compared to the two traditional lectures. However, the finding was not statistically significant.

[Table 1] reveals that the above finding is however not statistically significant. Further on assessment of the 14-point prevalidated feedback forms which evaluated the content, structure, presentation styles, and also offered room for preferences and suggestions, it was observed that most students favored video-assisted teaching (total mean feedback score – 61.99 and standard deviation [SD]) compared to the conventional method (total mean feedback score – 60.58, SD) on a total of 70. The increase in the mean feedback scores indicates the students' preference even though it was not statistically significant.

| Discussion|| |
In our study, it was found from the pre- and post-test evaluation that there was a significant gain in the knowledge in all four sessions which was significant and slightly more using video assistance although it was not statistically significant. Our finding is consistent with a similar study carried out in nursing students and the study also tried to match the findings to the sociodemographic variables of the purposively selected students which were not attempted in our study. However, the finding was not of any significance. The mean feedback for video-assisted teaching was 61.99 of a total of 70 while it was 60.58 for that without videos. This indicates that students prefer the usage of subject-relevant videos during lectures. Similar findings have been seen in previously carried out studies testing the efficacy of blended versus nonblended techniques.,,, Through the students' feedback obtained, it was indicated that the students preferred the use of videos, stating that it gave better clarity, was informative, and gave more room for interaction [Figure 2]. Similar reflections have also been revealed in previous studies., The students also expressed a need for more use of audio–visual (AV) aids in the form of related subject pictures and more videos [Figure 3]. Related studies have indicated that students have a preference for locally prepared videos/aids and that AV aids should be used purely to complement traditional methods and not to replace it altogether. This may explain the fact that students although expressed a preference for the video-aided sessions, they did not express an aversion for the didactic format, and the difference in the mean feedback failed to have any statistical significance. It came across uniformly through these various studies that blended learning was by far widely appreciated by the students, UGs, and postgraduates alike as compared to other passive formats of e-learning.

Both methods were found to be effective in terms of knowledge gained and students' feedback. This reflects that the students are happy with the traditional method of teaching; however, they find videos a useful tool to be used during lectures. Effectiveness with videos though favored by the students was not statistically significant owing to the small sample size. Using a larger sample size and a formal formative and summative assessment at the end of the teaching session with opportunities for feed forward may be a more effective method to explore the benefits of video assistance in teaching psychiatry for medical UGs. A focused group discussion may be a better way for collecting feedback, and we plan to explore the same in near future.
| Conclusion|| |
Both didactic and video-assisted lectures were effective in terms of knowledge gained and students' feedback. Using video assistance as a complement to lectures and not to replace the traditional methods is the way forward.
