Zoom Instructions for PhD Thesis Defenses

Transitioning to a virtual format for a PhD thesis defense requires careful preparation to ensure the process remains formal, secure, and academically rigorous. The following instructions outline the technical requirements, roles of participants, and protocols necessary for a successful defense via Zoom.

1. Pre-Defense Preparation

A successful virtual defense relies heavily on preparation. Both the candidate and the committee members must treat the digital environment with the same seriousness as a physical conference room.

Technical Requirements

• Stable Internet Connection: A wired Ethernet connection is strongly preferred over Wi-Fi to prevent connectivity issues during the presentation. If Wi-Fi is the only option, ensure the signal is strong and minimize competing bandwidth usage in the location.
• Hardware: Use a laptop or desktop computer with a working webcam and microphone. External webcams and microphones often provide better audiovisual quality than built-in components.
• Environment: Choose a quiet, well-lit room. The background should be neutral and professional. Avoid backlighting (sitting in front of a window) as it darkens the face.
• Power: Keep the device plugged into a power source to prevent battery drain during the defense.

Scheduling and Settings

The meeting should be scheduled by the departmental administrator or the committee chair. specific attention must be paid to the following settings:

• Waiting Room: Enable the Waiting Room feature. This allows the host to control admissions, ensuring the committee and candidate can enter and conduct preliminary checks before the public is admitted.
• Password Protection: Use a meeting password and share it only with authorized participants to prevent "Zoombombing" or unauthorized access.
• Authentication: Require participants to authenticate (sign in to a Zoom account) can add an extra layer of security, though this may be optional depending on institutional policy.
• Mute Upon Entry: Configure the meeting so participants are automatically muted upon entry to prevent background noise.

2. Roles and Responsibilities

Clear delineation of roles ensures the Zoom session runs smoothly. Below are the responsibilities for the key participants:

The Chair (Host)

• Starts the meeting 1530 minutes early to admit the candidate and committee members for a sound check.
• Manages the Waiting Room, admitting the public audience only after the defense has officially begun.
• Mutes all participants except for the speaker during the presentation and Q&A segments to maintain audio clarity.
• Facilitates the voting process and manages the Breakout Room for the committee's private deliberation.

The Candidate

• Joins the meeting 15 minutes early to resolve any last-minute technical issues.
• Shares their screen to display the presentation slides.
• Maintains professional attire and eye contact by looking at the camera, not just the screen.
• Ensures "Share Computer Sound" is enabled if the presentation includes audio or video clips.

The Committee

• Joins the meeting early to ensure their technical setup is functional.
• Keeps microphones muted unless recognized by the Chair to speak.
• Uses the "Raise Hand" feature or the chat box to indicate a desire to ask a question.

3. Conducting the Defense

The Presentation

Once the public is admitted, the Chair introduces the candidate. The candidate then begins screen sharing.

• View Options: The candidate should select "Side-by-side mode" if they wish to see the committee members while viewing their slide gallery.
• Q&A Interruptions: While questions are usually reserved for the end, some committees allow interruptions. The candidate should be prepared to pause screen sharing if the Chair requests a Q&A session mid-presentation.
• Slide Formatting: Use a 16:9 aspect ratio for slides to ensure they fit well on shared screens without letterboxing.

Questions and Answers

Following the presentation, the Chair opens the floor for questions. To manage this efficiently:

1. The Chair unmutes committee members one by one to ask questions.
2. If the audience is permitted to ask questions, they should use the "Raise Hand" feature. The Chair will call on them and unmute them.
3. The Candidate should repeat the question if the audience cannot hear the asker clearly due to audio lag.

4. Deliberation and Privacy

One of the most distinct aspects of a virtual defense is managing the transition from an open session to a closed, private session for committee deliberation.

Procedure for Deliberation:

• Once the Q&A is finished, the Chair will ask the candidate and the audience to leave the meeting or move them to a Waiting Room.
• Alternatively, the Chair can create a Breakout Room specifically for the committee members. The Chair initiates the breakout session, and the committee is automatically transported there, leaving the candidate in the main room (or a separate holding room).
• While in the Breakout Room, the committee discusses the performance and renders a decision.
• After the decision is made, the committee closes the Breakout Room. The Chair admits the candidate back to the main session to inform them of the result.

5. Recording the Thesis Defense

• Consent: The Chair must announce at the beginning of the session that the defense is being recorded. Depending on local laws and institutional policy, verbal or written consent may be required from all participants.
• Storage: Recorded files should be stored securely, typically on university-approved cloud storage, and not shared publicly without explicit permission.
• Format: Ensure "Record to Cloud" is selected rather than "Record to Local Computer" if a backup is desired, though local recording offers higher security as the file never leaves the host's drive.

6. Troubleshooting Common Issues

Even with preparation, technical glitches can occur. Here are quick fixes for common problems:

• Echoing/Feedback: If there is an echoing sound, two devices (e.g., a computer and a phone) may have joined the same meeting in the same room. One must leave or mute immediately.
• Low Bandwidth: If video freezes or audio cuts out, turn off HD video in Zoom settings (Video > HD) and disable all other devices using the internet.
• Screen Sharing Lag: Close unnecessary applications and browser tabs to free up processing power.
• Audio Drop-out: If a participant's audio is garbled, ask them to hang up and redial, or switch to "Join Audio by Phone" if the internet connection is unstable.

By adhering to these guidelines, the academic integrity of the PhD defense process is preserved, allowing the focus to remain on the scholarly merit of the candidate's work rather than the medium of delivery.
