Good evening from Indonesia dr. Goh, as the first panel for your topic is about technology in learning I am interested in the use of VR (virtual reality) for learning in medical education. Where the VR can make an experience where the user feel like doing something that simulated by the VR headset, from my opinion that is a big opportunity to use that formula for example, me, an undergraduate can do a full surgery  with minimal risk and also without needing a real patient or even a doll or props, and as what I know there is a VR game where we can be a surgeon even though the game itself solely can represent the real experience in real surgery. I am curious in your opinion, is it worth it to invest in VR like the headset and the application itself for learning in the medical education and how effective will it be?
Thank you so much for the opportunity doc, and warm regards from Indonesia

Good day Dr. Goh and all fellow participants of the Summer Course.

As we all know, the joy of learning is a lifelong process until our last breath. With technology advancement, the world of medicine and nursing have been evolving tremendously. However, how far are we to adapting this?

Personally, as a nurse and a mother of 2 young children, it seems tough because the 24 hours we all have appears to be lack and sometimes I wish I could have better time management to learn more.

I am interested to know the type of technologies that has been applied in your country and how has it help the healthcare providers. What has been the challenges face by others and how did all of you overcome it?

In my current organisation, there are some if not all, who are old school and still prefers the traditional way of paper and pens. I find they some may be quite tough to change, but we want to move on.

In this time of pandemic, the economy had turn into crisis, and the health care settings are not excluded especially when our country is also a medical tourism country. Then, the implementation of tele-consultation just began when in some other countries, it has been widely used. However, I wish to learn, how do you promote tele-medicine at this time of pandemic?

Theoretically, I may have learnt from a lot of articles you have shared, nonetheless, how prepared and how far are we that we want to move forward and engaged with technology? I admire the how Assc. Prof. Liaw has took a step forward and she leads by example. I wish I could be doing the same.

Overall, technology has bring us all 1 step further, and I will continue to learn and adapt, but time is essence, and I hope to gain a lot more knowledge and sharing with all of you.

Thank you once again for the insights shared by you Dr. Goh.

Much love,
MK, Malaysia.

Hello Mr Goh, Thank you for the opportunity. Through the method of exploring your padlet I discovered a lot of new things to learn, and I was very surprised that the use of technology is truly wider than ever. I found a lot of interesting things in your padlet and I want to ask some questions, how to secure our data when we have to use it most of the time in teaching and learning systems, how do you manage to adapt technology systems (its always evolving) and because our country is a developing country which is have many challenges, do you any advise or strategy how we can adapt with the technology evolving.
Thank you so much for the opportunity, warm regard from summer course participants

Hello Mr Goh, as an early-career lecturer, I fell that teaching in this pandemic era is quite exhausting. Nowadays, tendency to balance work-life quality is also a challenges for me. Since I work from home, turns out, Its really difficult to handle technical problems brought by internet covering issues in my area. Meanwhile, regulation on my office still prohibited frequent direct on-site access to office facility (such lab etc). Domestic environment that not specifically built to facilitate learning (I have 2 kids under 5 y.o at home =D) can also bit frustrating somehow. Beside, working at the hospital as a GP in this era also draining my energy sometimes. Finally juggling between all those things never been these nerve wrecking.  In other words, we are not ready for this. So that quite much adaptations needed to be made I guess. Not only from me, but also from my environment. Not only physically, but also mentally. I found many information very useful from your blog. Some information on how to becoming adaptive learner, also reminds me that I have to become an adaptive lecturer. Even if I am not fully adaptive yet (based on my experience, its really much harder to move faculties, rather than to move students in using technology mindfully), at least I found this activities really insightful and I glad that we are all "learn" on this together.  Thanks for the opportunity sir, warm regards from Indonesia.

Good day dr. Goh and fellow Summer Course participants!

Thank you for this opportunity and time to discover and understand a whole new range of ideas. It also appears for me that an advantage of technology is already apparent: I am able to share the struggles of adapting to this new digital era with others. The “work - home - COVID-19 - work/non-work” description in one of the posts was very accurate and relatable, thank you very much professor for sharing how to deal with such a situation.

A topic that I have found most useful as well in my self study is the Miller’s pyramid. It seems as if it is a very basic concept, but I find it helpful in identifying where I am in terms of understanding a topic I’m studying. I am sure that I will apply this concept regularly in my studies.

I want to learn more regarding the difference between analogue and digital learning. There were some differences stated such as analogue being “deeper” and digital being “superficial” studying. How does analogue learning facilitate “deeper” learning more than digital or TeL does? How do we make sure to have the same level of learning on a digital platform?

Thank you very much for your time professor!

Much gratitude,

CR, summer course participant

Panel I: Technology in Health Professional Education (HPE) self study

# data[].attributes.body
As I had read few (some) articles that professor wrote or refer at blogspot, I found and agreed that actually technology has opened many opportunities in education sectors. especially a very profound impact on learning and created many new possibilities in teaching and learning.

When learning working with AI and machine, we also had to add value to AI and machine learning and robotic systems so that we can develop along with the technology. We also need focus on 'soft skills', emphasising human communication, understanding and empathy; to add value as humans, in a technology infused environment.

As for me, adaptation is a challenge, from learning offline changing to learning online. I am not that get used of learning by reading long articles, and also, other I think that environmental is also a issue. When I take online class at my house especially bedroom, I feel that "this is not a place for me to study, but for me to leisure. study is at the cafe, or classroom, not here" but that's also a part of my adaptation against this COVID era.
I think soft skills learning is also a great selling point for health profession. As human need social, communication with robots, or AI may not be acceptable for many communities, especially in a developing country, as it is also not affordable in many aspects (like in a less developing region, in a "kampung" or  a village).
And also, I am very interested in learning soft skills online. I feel the need to know the concept, so that i may develop it in my personalize self study.

I am very sorry if I make some point and/or grammatical error. Thanks professor.

Hello dr. Goh and all participant of summer course

From self study, I learnt that the function of current technology to medical worker and the future of modern health technology. Especially the emerging of Artificial Intelligence that can change the landscape of medical care.

As more company research AI and use it for their product, it won't be long time for health related company to create AI that can learn to diagnose patient. In China, they successfully create a smart robot that can pass OSCE exam with more than 90% accuracy score.

This indicate that in the future doctor will work with AI to help diagnose patient and create suitable treatment plan. But will AI can do their job without supervision of doctor ? If  medical malpractice happen, who get blamed ? The AI ? The company that create AI ?

Overall, thank your for the learning opportunity, warm regard from summer course participants

Each participant of the Summer Course @ UGM should plan to post a personal short note on what you have learned and found useful in your self-study (of the content made available to you for my session on the blogpost, and this Padlet) at the end of this week. Do this as a separate individual post on Padlet, for each participant. This is similar to the end of workshop exercise that we do for a TeL in MedEd workshop @ CenMED, NUS (see illustration). This record of your personal learning journey (intermediate step) after week 1 of the Summer Course is a tangible, visible step of what you have personally found useful, and helpful. You can add to this personal Padlet post next week. And this Padlet post can form the foundation for further discussion with both your fellow Summer Course participants, and faculty. I am looking forward to over 100 Padlet posts by Monday 2 November 2020 - from each Summer Course @ UGM 2020 participant.
I will take note of what you have posted on Padlet, and adjust my Padlet postings accordingly. As well as what I cover in my upcoming "micro-lecture" session on 9 November 2020.

I encourage you to engage with each question.
On a daily basis.

Questions in Activity Board Summer Course 2020: Panel I

Panelists:

1. Dr. Poh-Sun Goh MBBS, FRCR, FAMS, MHPE, FAMEE

2. Prof. dr. Gandes Retno Rahayu, MMedEd, PhD

3. Dr. Louisa Matwiejczyk & Tony Arjuna, PhD

4. Uki Noviana, MNSc, PhD & team

Questions:

1. How do we get updated on the technology that is accepted and implemented in healthcare?

2. What can we expect in the transition of the implementation of current technology to high technology in health care or in education?

3. After the pandemic, is there any (national/global) policy about distance education in HPE or credit transfer from overseas?

4. For virtual reality, does this technique really make the students understand and will they be able to do it right with the real patient?

5. How to ensure the online learning in pandemic is efficient as offline learning for the students?

6. What about the ethical issue in digital case presentation?

7. Is there any suggested strategy that has been proven effective for encouraging and engaging people with low technical skills/low digital literacy & capabilities to accept and adopt some mobile application-based intervention?

8. How to start implementing TEL in remote areas? Because we know that access to technology is one of the challenges in Indonesia as a developing country.

9. What ethics influence technology in Health Professional Education to maintain confidentiality?

10. What do you think about telemedicine, whether this will be accurate in the history and diagnosis process?

11. The main problem in developing countries is financial and technological gap between one facility/place to another, what can we do to make sure that technology is well distributed?

12. Do you think technology itself could substitute human roles in the health field? Like will it cause less chance to be occupied?

13. If this pandemic is over soon, will we still conduct the online school? Despite all of the negative effects. Or maybe there is a possibility to mix both online and offline school?

14. Is there any funding opportunity nationally or globally for developing TELin one’s institution?

15. Developing TEL such as VR and other Artificial Intelligence-integrated tools are not as simple as we think. The developing process of TEL until they are ready to be implemented can't be finished just in a short period. What do you think about these gaps?

--------
Best Regards,
Novi

Dear Summer Course students, Padlet is an interactive digital wall, which for the purpose of this Summer Course @ UGM 2020 I have made open access for online viewing and posting - you are able to write, edit and delete your own posts, without needing to login (by just double clicking or double tapping on the Padlet wall, or clicking the circled red + button bottom right of the Padlet wall), as long as you use the same mobile or desktop device. Even though this platform works with all mobile and desktop devices, you will probably find using a laptop/workstation or tablet the easiest way to write and edit your posts on this website. Please consider identifying yourself, with at least your first name. You might also op to use initials, and omit specifying your institutional affiliation, in order to further anonymise your Padlet posts, as this is available for open access.
I have organised this Padlet wall for each new post to be placed at the top of the page, with oldest posts at the bottom. You can thus find your post as new posts are added by other participants. Please consider refining and adding to your post during and after the Summer Course on the same post, which you can do as long as you use the same device. We also encourage you to comment on other participants' posts also. Other members of the UGM Summer Course teaching faculty are also encouraged add to this online open discussion forum, by responding to existing posts, and adding new posts.
