This article has been divided in two parts. Part 1 explains what HyFlex is and which are the key points to consider before using it. Part 2 presents a wide range of teaching activities that can be used in a HyFlex classroom.
The Covid-19 pandemic has highlighted the need for new flexible approaches to teaching and learning to ensure excellent student experience. One aspect of both undergraduate and postgraduate teaching in physiology, that has been most affected, is the delivery of practical classes and skills teaching. This experiential mode of teaching is invaluable in supporting the taught, theoretical component of Bioscience education.
HyFlex teaching environments allow a combination of in-person and remote delivery ensuring no student is disadvantaged in terms of learning experience if they are unable to attend taught classes in person. It also allows such teaching to be recorded for upload and later reviewed by students to support learning. There are limited HyFlex teaching high spaces available across the College which are currently restricted to classroom spaces. We believe that greater availability is required to facilitate practical and laboratory skills training.
Whilst we had already recorded high quality videos of all the practical classes for our MSc course, in preparation of online delivery we were aware that this mode of education works best with supplementing a hands-on experience. Therefore, we sought a way for the students to gain some experience in the essential laboratory skills needed for understanding of the key mechanisms underpinning our teaching as well as providing skills training in techniques they would require in later modules on the MSc and in their research project.
During semester 1 in the current academic year (October 2020), we successfully ran 8 HyFlex teaching sessions in our teaching laboratories in the Centre for Human Applied Physiology (Shepherds House, Guys Campus).

We used commercially available low-cost portable equipment (owned by the authors) open-source software (Open Broadcast Software, OBS) to create a bespoke HyFlex teaching environment in one of our teaching labs following a full risk assessment.
As shown in Figure 2, i) two webcams (one for a wide-angle camera and one, mobile camera, for images of equipment and participants); ii) a radio microphone to ensure clear audio on both the recording and live stream and, iii) a PC laptop to run the software required for the experiment being undertaken and for video and audio mixing and broadcast were used.

All the sessions were recorded and uploaded to KEATS for revision purposes.
This approach was used for our module 7BBLM004, Cardiovascular and Respiratory Physiology, which forms a core part of the MSc in Human and Applied Physiology.
Due to social distancing and limits on room capacity we repeated each practical on 4 occasions during each day of teaching, with several students joining for both their in-person session as well as the remote HyFlex session at a different time point in the day.
The students were incredibly supportive and grateful for the opportunity to receive some practical teaching, particularly as some were unable to join the in person practical classes. Feedback from the students confirmed that the classes were beneficial and that the participants felt safe while on campus and in the classes (Figure 3).

We believe this approach offered enhanced participation to on-campus activities by those students who cannot attend in person for courses and modules which have a significant laboratory practical component.

Ged is an advocate for experiential learning and the benefits of practical teaching in human physiology.
In 2020 we used HyFlex technology in our Research Skills in Pharmacology workshops to recreate the interactivity of class discussions. It allowed students in the classroom to interact with students thousands of miles away, but couldn’t fully recapture the dynamics of small group discussions with everyone in the same place.

Education Elevenses are faculty-wide, peer-led, centrally supported regular meetings in which colleagues share practice and ideas about the pivot to online teaching. Continue reading “Education Elevenses – colleagues who teach face the pivot online together”
King’s Academic Skills for Learning was launched in September 2019 to provide students at King’s with resources to help them develop their academic skills. Students (and staff) can self-enrol via the KEATS (Moodle) dashboard. Continue reading “King’s Academic Skills for Learning on KEATS”
Face to face (classroom based) staff and student training and CPD can be both expensive and time consuming. Courses are delivered at fixed times, in fixed locations and offer limited flexibility for those who cannot attend the College physically. The breadth of courses is also limited by resources we have available, and the skills of staff we have delivering them. Courses can quickly become out-dated, as new software versions become available, and internal resources are not updated.
