New Knewton Store: We Do It Online

Here at Knewton, we have a lot of skills. Dressing up isn’t one of them.*

If you’ve ever been to our office in Union Square (check out this video if you haven’t), you’ve probably noticed our tendency to dress for comfort over style. In other words: sweatshirts, t-shirts, and, yes, even bare feet. (We do shower, though, we promise).

Which is why all our team members were so excited when we opened up the brand-new Knewton store, featuring super-comfortable and hip t-shirts (American Apparel brand!). After all, what’s a tech startup without awesome t-shirts? Our team members are already digging them (i.e., wearing them every. single. day) and we hope you will too!

Let your geek flag fly with our “Knerd” t-shirt, or go edgy with our “I do it online” design. We’re also shipping stickers with either slogan.

While you’re at it, be sure to check out some of the other startup stores we were jealous of inspired by: our favorites include the Foursquare, Runkeeper, and Groupme stores.

Finally, we’d love your feedback on what we should add to the store next! Fill out the survey below to weigh in.

*I’m speaking in general terms here; we’ve certainly got a couple of style mavens brave enough to break rank.

The Chronicle of Higher Ed: Adaptive Learning "Gives Students More Control"

In an article released today titled “The Rise of Learning Machines,” The Chronicle of Higher Education profiles Knewton’s partnership with Arizona State University. (This fall, Knewton’s Adaptive Learning Platform™ will power ASU Online’s College Algebra and College Math courses).

The article discusses some key features of Knewton’s Adaptive Learning Platform™ (“programs like Knewton can pace an entire math course using sophisticated tracking of skill development, instant feedback, and help levels based on mastery of concepts”), and calls attention to the underlying problems we’re working hard to address.

As Josh Fischman, the article’s author, writes:

The approach [adaptive learning] is attractive because of some unattractive numbers. Just 22 percent of students in the United States complete an associate degree within three years of starting, and only 57 percent complete a bachelor’s degree within six years, according to the Education Department. Such statistics, along with the large numbers of students who need remedial courses and drop out, drive the appeal of software that offers individualized attention to get students through basic math and other courses that are essential to college success. “These are high-risk, low-socioeconomic-status students—exactly the kind we have to reach out to,” says Mr. Regier [dean of ASU online].

How I Ensure Quality at Knewton

Hi there. I’m Daniel and I’m the Quality Assurance (QA) Lead here at Knewton. When I was approached to write this blog post I said, “I am but a humble QA man… what would I write about?” But then I started to think about what I do here every day and thought that it might be interesting for you to understand what kind of quality controls our products go through to ensure they are the best for you, our customers.

I’ve been here a little over a year now, and as the head of QA I can tell you we take quality VERY seriously. All of are products go through several cycles of testing, with different members of our staff looking for different things (some look at the content, some at the user interface, some at the data, etc.). For example, as the QA Lead, it’s my job to organize how the testing will be done and manage the issues that are found. It’s a pretty daunting task when you have tight timelines.

Part of what we do is manual testing. In other words, someone sits in front a computer and steps through the system, looking for problems. Manual testing is important, but often it’s not enough. That’s why one of my main responsibility is automation. We’ve built several automation frameworks. We have unit tests written by our dev team that test our infrastructure and a front end automation framework around Selenium and Selenium 2. Selenium is an open source automation tool (open source software is designed to be used by anyone; users can download and modify the code as they wish). Selenium allows you to write code that automatically runs tests against your website in any browser that you choose (e.g. Firefox, Internet Explorer, Chrome).

Having this automation framework allows for several improvements in our QA process:

  • It makes it much faster to test new applications or new features.
  • It makes it harder to introduce new bugs without us knowing.
  • It makes it easier to retest things frequently.
  • It allows us to get new features or bug fixes out to production more quickly.
  • It helps find bugs that might not be found by manual testing alone.
  • It allows the developers to test new pieces of code rather quickly.
  • It allows for much faster cross-browser testing.
  • It allows us to keep costs down as fewer people are needed for testing.
  • Tests can be run in parallel

There are, however, some drawbacks to automation as well:

  • Tests need to be written in a programming language so your QA people need to be able to code.
  • The tests need consistent maintenance.
  • It can be hard to get tests to work across all browsers all the time.
  • Test run in an actual browser can be slow.

Still, these drawbacks are small in comparison to the gains we achieve by having it.

So, how does all this testing affect our customers? Well, if a new feature is requested, a new product is needed, or we find a bug and need to fix it ASAP, this automation is crucial to allowing a fast turnaround while still ensuring we give you the best quality product possible.
