User Study

On 4th November, I conducted an usability test on the website For this purpose, I recruited two students from the University with diverse backgrounds. User 1 is a female Civil Engineering student who is fairly proficient with computers and has used sites like Coursera before. User 2 is a Computer Science student who is highly proficient student and uses Lynda on a daily basis. [1][2]

I recruited two students because I believe that Udacity is a very well designed website and it would be better to get opinions from two people rather than a single user. Also, because of it’s brilliant interface, I feared that the user would be able to complete all the tasks in very less time. Also, I asked both the users to sign the “consent to record” form which I had used in my previous assignment as well which looks like this. This test was also conducted in the study room of my apartment and the session was recorded in Quick Time player. This time I have avoided to post images of the session as I believe it would compromise on the anonymity of the user.

The tasks and their actions have been defined in the table above. I think this time I was more clear about what exactly needed to be done. My tasks are better phrased and also I have built up scenarios in a more believable way. I had to repeat my tasks the last time when I conducted the test or phrase it in a better way, but this time the problem did not arise. I could conduct the test in a much better manner.

Interesting and Surprising Points [5][7]

What I found the most interesting was the fact that none of the user watched the video about nanodegree on the home page. Sure, it is a very beautifully designed video which clearly explains what the nanodegree program is about but it is of no use if people do not decide to watch it. I am not stating that they should get rid of the video, I am just reinstating the fact that they need a little blob which conveys what the nanodegree program is about.

Another interesting point is a very general point. The home page of the website is a single page website where you have to scroll down and down to view the options in footer. But when there is so much scrolling involved, one might never know that there is a footer section. In this case, the footer section has lots of important links which might be useful for the users and employers alike. Both of my users were not able to navigate through the footer which I thought they would.

What the users didn’t do and why?[6][8]

Again the fact that the users did not watch the video was very interesting to me. They just assumed the meaning of nanodegree. User 1 was able to guess it correctly while User 2 could not do so. Also, I thought the User would have a problem with the usage of the word catalog but it was surprising that the users were quite familiar with that term. May be because the term is also used on Coursera that this problem did not arise. Another interesting thing that the user did not do was to use the filter options when they were trying to search for the Nvidia course. That is how I did it, but the users were more comfortable just searching for the course.

Also, Scott Berkun notes that it is important to know who the customer is in [9]. Here the customers are mostly students. And students normally like knowing the price of things before they get interested. But the price is only displayed to the customer at the very end. I am giving the website the benefit of the doubt and not calling it a dark pattern  but it might be. ( [9].

Redesign Speculations, list of flaws and solutions[10]

  1. Payment information: I believe that this is a pretty big problem with this site. Not knowing what you are paying for could be a deal breaker for a lot of people (especially students). This could be solved by simply putting a payment option in the below shown image part of the website. android_basics_nanodegree_by_google___udacity


2. Search Box: The catalog button contrary to my beliefs turned out to be easily discernible. But the users did point out the need to have a search button on the website. So, just using a Coursera like Search+Catalog option would be a good idea.


3. Scrolling: I like the fact that they have all of their information on the home page. But what it is doing is introducing a lot of scrolling to the home page. I believe that this is a very heavy trade off for a website which has a lot of interesting links in the footer section. Nielsen talks about an “aesthetic and minimalist” design [9]. I believe that should be followed in this case.

4. Sign up/Sign in: Udacity has the sign up/sign in option in the my classroom area of the website. I think it is a pretty standard practice to introduce those options on the home page. So, I would get onto that as soon as possible.

Overall, it is a very well designed website but such minor fixes would improve it exponentially. Many of my earlier criticisms have been completely revamped in the website’s latest iteration but these fixes still need to be addressed.
