At Knewton, we work hard every day on the world’s leading adaptive learning engine. We also have enjoy some great perks, like an open pantry, free Metrocards, unlimited vacation days, nightly dinner, and more. For one of our quarterly Hack Days, I created a video to showcase a typical “day in the life” of a Knerd. To learn how you can become a Knerd, too, check out open jobs.

Item Response Theory models student ability using question level performance instead of aggregate test level performance. Instead of assuming all questions contribute equivalently to our understanding of a student’s abilities, IRT provides a more nuanced view on the information each question provides about a student. It is founded on the premise that the probability of a correct response to a test question is a mathematical function of parameters such as a person’s latent traits or… Read more
The advent of “big data” in areas such as internet search and social media has disrupted existing industries, created new industries, and led to the extraordinary success of companies such as Google and Facebook. Big data unleashes a range of productive possibilities in the education domain in particular, since data that reflects cognition is structurally unique from the data generated by user activity around web pages, social profiles, and online purchasing habits.

Teachers for decades have understood the importance of “differentiated instruction” — the process of tailoring instruction to meet individual learners’ needs. This framework or philosophy is nothing new. What is new is technology’s capacity to produce truly differentiated instruction. In this video, members of the Knewton academics team explain how Knewton recommendations steer students along personalized paths towards ultimate learning objectives based on both what they know and how they learn.
At Knewton, we like to experiment with data visualizations. The above visualization shows the history of developer contributions to the Knewton Adaptive Learning Platform (Post Git). Contributions are measured in “commits” which occur whenever a developer alters the code and transfers the changes into our central git repository. Each file in a commit is represented by a colored-coded blob which indicates the type of file committed. Each time a developer commits a file, the algorithm… Read more

This post was co-written by Kristen Tracey. Scalability vs. Perfection: that’s really the issue at hand any time you need to make a large number of videos. Of course, we want every educational video we make to be perfect — clear, engaging, and without any stumbles. However, the reality of producing lots of videos is that you simply can’t always fix everything. Editing educational videos, like any other web videos, is all about balancing scarce… Read more
This post was co-written by Jess Nepom. There has been a lot of talk lately about creating educational videos for your students, whether you mean to use them in class, on the web, or both. Fewer people really talk about the different options for the format of your video — by which I don’t mean the technical file format, but rather the actual style of what will be on the screen. Should you use an… Read more
In the world of education, technology is finally taking center stage. For decades, education watched as tech transformed other industries — retail, entertainment, information, advertising.
