I'll be presenting research team's paper on approaches to CS Teacher education at 2017 AERA. Learn more about the presentation here, and below is the abstract:
Today Ryan and I had a good discussion of the existing and potential use cases of Vialogues. I think EdLab blog is a good place to archive and share our discussion. If any of our research associates is motivated, I think expanding this topic can make a good publication on the pedagogical models of video-based discussions. Additions, comments, and suggestions are also welcome.Video AnnotationVideo Annotation is an important tool in anthropology research. Researchers shoot videos about human behaviors and...
This Wednesday, at the Research Team Share-out EdLab Seminar, I will be presenting some of the work the research team and I have done to make the best use of the Quuppa location tracking system. I will focus on a paper we recently wrote titled "Cluster Analysis of Real Time Location Data - An Application of Gaussian Mixture Models" Breaking down the title, we are trying to identify groups or clusters within a snapshot of 2-dimensional (x,y) Quuppa location data by using a statistical concept called Gaussian Mixture Models. In my presentation I will also highli...
Topic modeling is usually used in text mining to discover the main topics of documents based on the statistical analysis of the vocabularies and their related topics.   (Graphic concept illustration: Charles Lang, HUDK4051 Learning Analytics lecture notes @Teachers College, Columbia University)...
One of the potential research projects I want to tackle in the coming months is on immigrant students (and maybe refugee students) and how they direct their own learning. There is an often held belief that children of immigrants (especially first generation) often have high academic attainment. The phenomenon, dubbed the “immigrant paradox,” looks at some of its underlying reasons such as grit and motivation. However, Professor Cynthia Feliciano at UC Irvine argues that there is a more compelling reason for immigrant student success: that immigrants simply work their way into the social cla...
There are a lot of free online visualization tools. It all depends on that type of data you have and what tasks you want to complete. Below are some of the best ones I’ve seen or used. Figure 1. Flowchart of data visualization tool choosing If you have ...
As we are re-designing the Vialogues application in order to improve its effectiveness in supporting educational dialogues, the following research is particularly relevant:C. Clark, N. Strudler, and K. Grove (2015). Comparing Asynchronous and Synchronous Video vs. Text Based Discussions in an Online Teacher Education Course. Journal of Asynchronous Learning Network, Vol. 19, Issue 3.In this research, the authors compared a text-based ...

One interesting and potential application of mixed reality at Smith Learning Theater is prototyping in mixed reality at a design event. I ran into this paper on prototyping in virtual reality, and it presents several useful guidelines for planning such activities. These points are helpful as we cons...

After the Design Team's Way-finding Seminar last month, and in preparation for the opening of the Learning Theater, I have been exploring a few of the options mapped out by the EdLab crew. One that really struck me was adding Russell Hall to a pre-existing way finding app like Google Maps.  In their infinite wisdom Google has provided an indoor mapping option on their open platform ...
Hi everyone! I'm pleased to present our video for the winner of the 2015 Strage Prize, Sonali Rajan. You have probably caught snippets of this video in the sound dome out in the hallway, but here's your chance to watch it in full! Sonali's research investigates the roots of adolescent gun possession and highlights how health education can lower the risk of gun violence among youth by creating a safe and inclusive school environment.
