Table 1. Challenges faced while developing the teaching plan and their solutions.

Sl. no.	Challenges faced	Strategy devised to overcome it
1	Internet connectivity: for the smooth conduct of the online classes, an uninterrupted internet connection with good speed is required.	The institute’s wi-fi connection was used. In addition, three to four mobile wi-fi networks were kept as backup.
2	Availability of volunteer: owing to the ongoing COVID-19 pandemic and implementation of COVID-19 protocols, it was difficult to find subjects for demonstration of practical skills.	The issue was resolved to some extent by using a full-body mannequin for demonstration of certain procedural techniques. For others, the help of a consenting volunteer was sought and all COVID-19 protocols were maintained.
3	Selection of a suitable online platform: This was a challenge because of the presence of audio and/or video lag in some platforms and restriction on the maximum number of participants allowed in free versions.	Trial sessions with students and faculty members were held on several platforms, and the decision regarding the platform to be used was taken based on the feedback received from the students and faculty members.
4	Maintaining student attention: Holding students’ attention and ensuring their involvement during the class is a challenge on any online platform.	Several opportunities were provided for student-teacher interaction prior to, during, and after the class in the form of PowerPoint presentations, assignments, live demonstration on an online platform, and small group discussions to ensure active participation. The live demonstration especially helped replicate a face-to-face session.
5	Requirement of equipment and financial implications: Conducting the online live demonstration required a full-body mannequin and materials for recording (camera, tripod stand, etc.).	Approval for funds required to purchase the required items was sought from the institute authorities. Live demonstration was done in a smart classroom with camera and internet facilities. In addition, mobile cameras were also used to record from different angles to provide a clear view.
6.	Time constraint: The entire teaching plan had to be devised within a very short span of time due to sudden imposition of lockdown, resulting in suspension of offline classes.	This was made possible by a dedicated group of faculty members who devoted a significant amount of time to develop the strategy, study materials, and assignments followed by intradepartmental review and revision. Also, the active participation of the students, including their feedback helped in improvising the plan on-the-go.
