Thanks Gonzalo and Pan for a great wall!
I found this super cool video that I have pitched as a Vialogue, and I wanted to share it! Digitization is an extremely time-consuming process. Large institutions need to devote years or even decades in order to digitize their enormous collections. The Smithsonian found a way to speed up this process: by using machines! For everything to be digitized within the Smithsonian through the slow method of individually digitizing each item, it would take somewhere close to 11,000 years to digitize each of the 138 million objects!
The Smithsonian is currently digitizing a collection of about 60,00...
I have been exploring the R library qdap recently and it has many functions for doing exploratory analysis for dialogues.
Here is something I just found by using the function "question_type" in this library. This function counts the occurrences of different types of questions, such as "where", "why", and "how", in the sentences. I grouped the sentences according to the ratings of the vialogue conversations they belong to. See the plot below for the result. We can make a few interesting conclusions:
Vialogue 16171 talks about the Advanced Placement (AP) courses offered in different high schools which reflects the problem of educational inequality and some possible intervention methods. We applied the hidden topic Markov models on this vialogue. More specifically, we assumed that the comments from an individual post share the same topic and we treated the comments within each timestamps as individual documents.
Here is what we found. We used four different colors to represent four different topics: topic 1 is red; topic 2 is gre...
My current research is evaluating topic coherence of discussions and their corresponding videos. Both YouTube and Vialogue discussions are related to the posted videos. However, discussions on YouTube's platform is a forum discussion while Vialogue enables moderated time-stamped discussions. We are trying to research whether on average, the same piece of educational video on the two platforms result in different levels of topic coherence. I am now in the process of solving this problem, and I am fascinated by the approaches.
1) Learn and discover, not reinvent the wheel
In the past...
Add your thoughts and questions to Dr. Gary Natriello's seminar on EdLab 101!
As a designer who's been an in-house designer for quite some time, I've always been interested in solving a particular kind of challenge: How can we, ourselves, utilize ‘new' things and new technologies without the need or expense of an agency solution?
We are in the middle of planning for a new exhibition in January: “The Voice Show, 200 Episodes” (tentative title). "The Voice”, in Teachers College Record (TCR), will have its 200th episode in November, and we'd like to highlight and share its tremendous value with the Teachers College (TC) community. Ideally, we'd like to select, organize ...
The TC125 History Show has begun on the third floor!Â In honor of Teachers College's 125th Anniversary, the EdLab design team began installing the exhibition which will depict significant events in TC's history.The third floor space utilizes a loose timeline structure divided by themes. The content displayed was gathered by the library services team and more content will be added throughout the year as the show progresses. Please feel free to email us with any noteworthy events you can think of!
All text is cut vinyl (thin plastic sheets with adhesive backing).Â Installation of the exhibiti...
Below is a question on Quora asked by a user to which another user replied with the EdSurge blurb on ResearchBroker.
I think it is exciting to see that people can relate ResearchBroker to solving the same problem for which it was built: i.e. to bridge educators and technologists. I am happy to see that people can get that without us speaking to them on the phone necessarily or sending them some fancy product blurbs. Th...
