Correcting Automatic Transcripts of Curricular Video Recordings at UICOM

Around 2019, some of our international students at the University of Illinois College of Medicine (UICOM) met with me to talk about the automatic transcripts created for all of our video content in our video storage system, Echo360. We had turned on the transcripts feature in spring 2019 as a pilot to determine the accuracy of the built-in automatic speech recognition (ASR) in the program and figure out how to best provide students with additional ways to consume the videos.

What we discovered pretty quickly is the accuracy was sometimes really poor. After discussions with Echo360 representatives, we found out that there is not a built-in dictionary for medical, pharmacologic, and certain higher level scientific terms. For example, if a faculty member said ‘hypoallergenic’, the system might not have heard it correctly and the transcript would show ‘hyper-allergenic’ which is incorrect.

Initially, some of these brave medical students tried to correct the transcripts themselves and soon discovered just how long it can take to correct them. We determined that a better option, until Echo360 has the dictionaries in their system, was to hire non-pre-med students to edit the transcripts. I worked with my colleague Dr. Elizabeth Balderas to interview and hire 5 students to do this work. This is still a work in progress and we hope that eventually the company will incorporate a medical dictionary.

Here is an example of how the system incorrectly heard the term ECG from a faculty member who was speaking. The correct term is ECG. After listening to this part of the lecture. it was very clear he said ECG, not eggs.

It is really imperative that we correct these transcripts. There are students who have learning disabilities or other accommodations. Sometimes we have faculty who have thick accents because English is not their first language and we have students who’s first language is also not English. We need to be able to provide the best education to all students.

Redesigned Online Course for Northern Illinois University V2

After redesigning and teaching ETT 555 Media Design: Multimedia at Northern Illinois University (NIU) in summer 2020, I realized that the Ultra view in Blackboard wasn’t really cutting it so I went back to the Original view for spring 2021. I relied upon my own instructional design skills as well as feedback from students and my mentor, Dr. Cindy York.

Here are some images of the changes I made for this offering. This first set of images show the Announcements page and the Welcome page. (Note the arrow to see the other image in the gallery).

Here is the schedule for the course. The image is pretty long and unwieldy to show it visually here. When you click on the image in the link, it shows up quite large so you may have to scroll left / right to view all of it.

Below is a sample of a weekly module. This one shows week 5 of an 8-week course.

Here, you can see the assignments for the course.

Finally, here is an example of a rubric for an assignment. All assignments have specific rubrics attached to them.

The course still has a few weeks to go this spring, but I will certainly review feedback on it if I end up teaching it again.

Redesigned Online Course for Northern Illinois University V1

For summer 2020, I redesigned a graduate course called Media Design: Multimedia (ETT 555) and taught it during an 8-week term. I converted the course to Blackboard Ultra view from the Original view for this particular delivery. As it turned out, the version of Blackboard Ultra used for this course was lacking in some useful functionality for both instructors and students.

Here is the image showing the course topics and schedule.

Also for ETT 555, here is an image showing an overview of each of the modules.

And finally, here is a listing of the resources for students to use to complete the module exercises.
