Makes sense. When you assign students to replicate a full system, what criteria do you use to evaluate both their technical implementation and their understanding of the underlying machine learning concepts?
Interviewer 0:11:10
That’s clear. When students encounter unexpected results or errors while replicating your full system, how do you guide them to diagnose and learn from those mistakes rather than just correcting their code for them?
Dr. Herlin L T 0:11:15
Go step by step. Adding each step.
Interviewer 0:11:16
That step-by-step progression helps reinforce learning. When guiding students through adding each new component to their system, how do you encourage them to document their process and reflect on design choices as part of their project work?
Dr. Herlin L T 0:11:20
Procedure by procedure. To improve.
Dr. Herlin L T 0:11:23
Russells and later on.

Dr. Herlin L T 0:12:46
And finally.
Dr. Herlin L T 0:12:47.0
Will come with a new.
Interviewer 0:12:44
Thanks for clarifying your team structure. When you conduct those final meetings with faculty mentors and team leaders, what criteria or evidence do you use to evaluate if the student teams have truly understood the technical concepts, rather than just completing the assignment?
Dr. Herlin L T 0:12:49
Solution.
Interviewer 0:12:47
Thank you for describing your process. When you hold those final evaluation meetings, can you share a specific instance where faculty mentors and team leaders disagreed on a student team's readiness, and how you facilitated a resolution?
Interviewer 0:12:48
Understood. When you reach that final stage and present a new system or solution, how do you document the process and outcomes so that future student teams or faculty can learn from the experience?
Dr. Herlin L T 0:12:51
After the meeting.
Interviewer 0:12:50
Thank you for detailing that collaborative approach. Can you provide a concrete example of a project where this breakdown and team leader system led to a particularly successful or innovative student solution?
Interviewer 0:12:52
Understood. When you reach that point of presenting a new solution after the team and faculty discussion, how do you ensure that the contributions of individual students are accurately recognized and not overshadowed by the group outcome?
Dr. Herlin L T 0:13:17
So the individual students are monitored.
Interviewer 0:13:18
Thanks for clarifying. Can you describe a specific method or tool you use to track and document each student's individual progress throughout the project cycle?
Dr. Herlin L T 0:13:25
Day by day. And each student has to. Report.
Dr. Herlin L T 0:13:27
To the team leader.
Interviewer 0:13:26
Thanks for clarifying. How do you ensure that daily student reports are meaningful and not just a formality—what do you look for in those reports to gauge true engagement and understanding?
Dr. Herlin L T 0:13:36
And he's responsible for. Monitoring the work. And if there is any deviation. He'll inform the faculty mentor.
Interviewer 0:13:28
Thanks for clarifying. Can you give an example of how you handled a situation where a student's daily reports indicated a lack of progress—what specific steps did you or the team leader take to address it?
Dr. Herlin L T 0:13:39
I inform myself.
Interviewer 0:13:37
Thank you for explaining that reporting process. When a team leader notices a deviation and informs the faculty mentor, can you walk me through the steps you expect the mentor to take to address and resolve the issue?
Dr. Herlin L T 0:13:44
To coordinate the work. Or to properly monitor all the e-mail.
Interviewer 0:13:40
Thanks for clarifying your process. Can you describe a specific instance where you, as the faculty mentor, had to intervene directly due to a student’s deviation—what actions did you take, and what was the outcome?
Interviewer 0:13:45
Thank you for outlining your coordination approach. How do you balance providing oversight as a faculty mentor while still allowing team leaders and students enough autonomy to develop their own solutions?
Dr. Herlin L T 0:14:29
As a faculty mentor. I love like dumb. I'll ask them to. Gain ideas ariqua an overview of them. If they have any clarification. Locations they can clarify. Also, they have the profession. Of attending.
Dr. Herlin L T 0:14:31.0
Workshops if.
Dr. Herlin L T 0:14:33
Seminars.
Interviewer 0:14:31
I see. Given your approach, can you share a time when allowing students this level of autonomy led to an unexpected solution or insight that you might not have predicted as a faculty mentor?
Interviewer 0:14:32
Thanks for sharing your approach. Can you give a concrete example of a time when a student's participation in an external workshop directly enhanced the quality or direction of your team's project?
