This morning the development team was discussing the merits of auto-save (as opposed to only saving user inputs after clicking on a Save button. This is a summary of what I think.The ProblemThere are several popular approaches to saving user inputted data but there's no obvious winner.People say when you are designing an application, you need to be consistent, but is that what people are doing (se...
As people age, the notion of having a role model seems ridiculous. Role models are generally associated with children. However, as adults, especially in these uncertain times, we can all use role models. In this piece, the Professor Susan Krauss Whitbourne (Amherst) makes such a case. She argues that society at large tends to ignore positive role models because it is simply not “sexy”. News stories and social media rewards negative behaviors (e.g. drunk driving, assaults) from celebrities by ...

MIT Tech Review wrote an article to review Loeto, Servedio, Strogatz, & Tria (2017): Dynamics on expanding spaces: modeling the emergence of novelties. The researchers found a mathematical way to identify novelty/innovation from the language. This is great, isn't it? Perhaps we can use this method to measure the degree of novelty of the articles on TCR, NLT, and EdLab blog.

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)...
