Q1. How do I get started with mixed mode teaching?
A1: You can refer to our resources page on http://cei.ust.hk/getting-started-mixed-mode
Q2. Can F2F students and online students be in the same discussion group?
A2: We recommend grouping F2F students with F2F students and online students with online students. If grouping students from both sides is unavoidable, be aware of the serious audio feedback and echo during class. To know more, please see next question.
Q3. Why can't F2F students join Zoom in the classroom? What is the downside?
A3. There will be serious audio feedback and echo when F2F students join Zoom with their microphones unmuted and/or not using headsets. It happens in most classrooms, and such disturbance will also affect online students.

As F2F students cannot speak up flexibly through their microphones due to the audio feedback, interactive/breakout activities cannot be conducted in Zoom easily. To avoid this kind of technical hiccup, we do not suggest having F2F students joining Zoom in the classroom if you plan to have interactive activities in the class.

Alternatively, the issue can be resolved by asking ALL F2F students to join Zoom with headsets and mute their microphones throughout. When F2F students would like to speak up, instructors can either circulate Mic4Me or activate the ceiling mic, so that online students can also hear clearly.

Q4. Can my students work in the same group throughout the semester?
A4. As students will turn up F2F or in Zoom week by week, it is hard for you to pre-assign students into groups. The collaboration is also challenging for student groups when mixing some members in the classroom and some online. Therefore, random grouping is a more flexible approach in Mixed Mode teaching.

If pre-assigning students into groups is unavoidable, we suggest instructors either schedule some sessions for student groups to work online or ask student groups to sign up every week with the whole group committed to either join F2F or online.
Q5. How do both online and F2F students do polling activities?
A5: For Mixed Mode teaching, we recommend using iPRS instead of Polling in Zoom.

Refer to https://itsc.ust.hk/services/academic-teaching-support/teaching-tools/prs/iprs for details.
Q6. How do I answer questions from online students during lecture in Mixed Mode teaching?
A6. In Mixed Mode teaching, apart from leaving messages in Chat, online students can speak up in Zoom. Questions will be piped through the classroom speakers and to be handled by the instructor in real time.

If you adopt Mixed Mode Lite, chat questions can be handled by the TA in real time, and you can also back up the chat messages and address the questions afterwards.
Q7. Do I need TA support if my class is mostly just lecturing with limited interactivity?
A7. In this case, you may consider taking the Mixed Mode Lite approach. If you have TA support, he/she can support the Chat inquiries real time in Zoom. In most lecture scenarios, it may be enough for the instructor to break between topics and check the Chat for any inquiries.
Teaching Support (TAs)
Q1. How do I ensure my TAs are trained to support my class?
A1. You should communicate with your TA about your teaching plan each week. Then, convey to your TAs your expectation clearly, so that they know how to best support you. Conducting dry-runs and having more frequent meetings with TAs throughout the semester would definitely help your TAs understand your needs.

To understand more about the role of instructor and TA in Mixed Mode, refer to the sample teaching plan.
Q2. How can my TA interact with online students - chat or audio?
A2. If the TA is going to stay with you in the same room, the TA should not join Zoom with audio to avoid audio feedback and echo. They should mainly use chat to address online students' inquiries.

Q3. Should I prepare at least one laptop for my TA to manage online students?
A3. Yes. The TA should have a laptop, especially when the class is conducted in Mixed Mode teaching. The TA will coordinate with online students and handle administrative tasks, such as answering in Chat, forming breakout groups, making announcements, etc. with the laptop.

Q1. How do I set-up the classroom for Mixed Mode Teaching?
A1. You can refer to Step 5 in our resources page http://cei.ust.hk/getting-started-mixed-mode
Q2. Can F2F students see the chat messages in Zoom during class?
A2. Yes. You can open the Chat window, so F2F students can see the chat messages in real time through the projector. However, you may want to consider if the chat message would distract F2F students from their learning before making it available through the projector.
Q3. Can I use my own laptop instead of using the classroom pc for mixed mode teaching?

A3. You are recommended to use the classroom PC, as the classroom PC is connected with the standard equipment for Mixed Mode teaching, such as

  1. Mic4Me system for capturing the instructor's audio into Zoom
  2. RVC feed for showing the wide classroom environment to Zoom
  3. Visualizer for projecting written work or simple demonstration through Zoom
  4. Ceiling microphone system for capturing F2F students' audio into Zoom

If you use your own laptop, you are recommended to perform a dry run in the classroom, especially to test the capability of piping the audio/video input to online students through Zoom.

Q4. What are whiteboard options for mixed mode teaching with a lot of writing/drawing?
A4. You may consider projecting your hand-written workings through the visualizer or you can request for RVC feed from MTPC to capture the classroom whiteboard. MTPC's operator controls the RVC camera to follow the instructor and writing on the whiteboard.

Please see the next question, Q5 if you want to use an iPad.
Q5. How do I annotate teaching materials using iPad when conducting Mixed Mode teaching?

A5. To display the content from your iPad to online and F2F students, do the following steps:

  • Although you are able to sign into both the iPad and the classroom PC with your ITSC account concurrently, you are recommended to apply for a project account for the iPad to ensure the features in the Zoom meeting are fully functional.

    You can apply for the ITSC project account here, it will be available to you one day after the application.

To get your iPad configured before class starts,

  • Start the Zoom Meeting using the classroom PC
  • Open the Zoom app in your iPad, join the meeting with the project account
  • In the classroom PC, assign the iPad as the co-host
  • In the zoom meeting controls of the iPad, tab 'Share content', 'Screen' and select 'Start broadcast'
  • Switch to the app with your teaching materials in the iPad

Meanwhile, the classroom PC should be showing the iPad's screen through the Zoom window, F2F students can then view it through the projectors.

In case of switching the video (i.e. your talking head), you can switch between the webcam of the classroom PC and the iPad front camera using the "Spotlight video" feature in Zoom.

We recommend using iPad Pro with Apple Pen to get the accuracy and smoothness for teaching, especially for mathematics, chemical formulae etc. Furthermore, you should ensure only one device is unmuted at a time, or students will get terrible audio feedback.

Q6. How would not using a microphone or Mic4Me affect online students?
A6. If you stand close enough to the webcam, you can still select the webcam as the alternative to capture your audio input. However, using Mic4Me would bring a more consistent audio quality to online students in case you need to walk away from the webcam during class.
Q7. How can online students hear F2F students during class?
A7: Most of the classrooms are equipped with a Mic4Me system. You can borrow an extra Mic4Me device for capturing F2F students' audio into Zoom. As the Mic4Me supply is very limited, we recommend instructors only borrow extra Mic4Me for conducting interactive activities, such as in-class discussions and student presentations. Contact your department or ITSC Helpdesk if you need an extra Mic4Me.

For other classrooms without Mic4Me, typically they are small classrooms, online students can hear F2F students through the webcam on the classroom PC. We recommend using the wired mic to help amplify the audio level through the speaker for the webcam to capture.
Q8. Can RVC capture two projector screens throughout my lecture? (PowerPoint and iPad annotation)
A8. Not all projectors can be captured clearly at the same time. Please specify your requirements when you request for RVC feed service from MTPC.
Q9. Webcam vs RVC feed, can online students choose which video source to watch in Zoom?

A9. Online students cannot choose the video source. In addition to the instructor's share screen, there are two Zoom video display options the instructor can choose to show online students:

  • Choose Webcam to show talking head when teaching in front of the podium
  • Choose RVC Feed to show the wide classroom environment when instructor is walking around or using the whiteboard. Note: Please book RVC Feed through MTPC
