Behind the Construct: Code Overview 2023 

Because the yr involves an in depth, we went by means of information about learners in our group and pulled collectively a few of the biggest highlights of 2023, known as Code Overview. That is principally a data-driven deep dive into the subjects that learners such as you linked with, the initiatives you all labored on, and the programs you spent essentially the most time with this yr.  

To drag off Code Overview, we aggregated anonymized information for our learners to floor the trending instruments, subjects, and programs over the previous yr. You could find the complete recap and discover extra of our findings on the weblog, just like the high coding programs from 2023, the hottest initiatives and Docs, and an interview with a learner who’s maintained an eight-year studying streak.  

If you happen to’re inquisitive about information science, you may be curious simply how we pulled, analyzed, and located tales inside this information. Code Overview was a cross-departmental collaboration between our product, information, artistic, and engineering groups. Forward, our Product Advertising Lead Donté Ledbetter and Knowledge Analytics Supervisor JR Waggoner clarify how Code Overview went from a hackathon concept to a actuality.

Study one thing new without spending a dime

The undertaking: Spotlight the progress our learners made in 2023 by means of information 

We wished to look again and determine essentially the most fascinating and entertaining information about our learners’ habits and the way they engaged with our studying platform in the course of the previous yr. “Spotify set the pattern again in 2016, so plenty of firms do that form of factor,” Donté says. “Folks prefer to really feel like they’re making progress, and this was a great way to point out the progress our learners made all year long.” 

The principle duties our crew needed to accomplish to create Code Overview have been: 

  • Collect anonymized information from our information pipeline 
  • Mannequin the info with SQL and dbt (aka information construct instrument)
  • Discover a artistic strategy to share the findings with our group 

Investigation and roadmapping 

Donté: “We began speaking to the info science crew in Could to see what this could possibly be like, and if we even had the info out there to mixture and ship to individuals. [My role] was principally simply being the undertaking supervisor; ensuring it will get finished and doing the legwork upfront to persuade individuals it was price doing. As soon as we determined we have been going to do that, I gave steering on its execution and advertising and marketing impression. 

The thought had been pitched in hackathons for years, so I principally pushed it ahead to get it finished this yr. It’s cool once you get to point out individuals the progress they’ve made, as a result of in edtech, individuals need to really feel like they’re making progress.”


JR: “The information crew drove a lot of the technical aspect of the undertaking. We began out in additional of an advisory capability as Donté and the product crew threw out totally different concepts. As soon as we moved out of that preliminary planning section, we clicked into going out and gathering the entire totally different belongings and metrics. We have been type of simply happening an journey to seek out the info, throw some fundamental statistics at it, and see what we may do. 

A number of the issues that we have been requested for are our bread and butter, issues we do day-after-day. However there have been some extra fascinating questions that had by no means actually been requested earlier than. These questions did require some new information modeling — going out and discovering new stuff and determining easy methods to work with it. They weren’t tremendous difficult [asks], extra ‘how can we reply this query’ than ‘do we have now the info for this.’ 

We now have a reasonably intricate information pipeline that we use to measure how customers prefer to work together with our web site or work together with our content material — enrolling in programs, submitting code, engaged on initiatives, and so forth. In some circumstances, easy SQL queries have been all we wanted. For the extra fascinating/advanced questions that required extra advanced information modeling, like those who concerned a sequence of advanced interactions over time, we typically turned to dbt. dbt is a superb instrument for manipulating information and modeling advanced information pipelines, and we use it to energy a lot of the analytics at Codecademy. So, dbt is the place we did a lot of the information heavy lifting for this undertaking.” 


JR: “Knowledge engineering is usually very very like conventional software program improvement. Different instances, it’s the Wild West. You’re taking this listing of metrics or information factors that the crew has compiled and changing them into what we all know from the info. 

For essentially the most half, we all know the place to seek out the info factors we need to discover.  From there, we obtained into the extra technical a part of writing no matter code we wanted to write down to make sense of the info, ensuring we captured the entire metrics, checked all of the containers, and introduced all of it collectively right into a single, simple to devour mannequin for the undertaking. 

We wished to discover a few alternatives in areas we’ve by no means been earlier than, however the worth of doing so must far outweigh the raise required. We perceive lots about how learners have interaction within the studying setting — what they submit, how lengthy they spend on totally different duties, and so forth. —  however even right this moment, there are nonetheless some points of how customers work together with our content material that we’ve by no means explored. 

There have been some crazier, extra aspirational concepts from the outset, however we couldn’t scope what getting there would even seem like. Other than that, the most important problem was common noise. There are at all times these bizarre edge circumstances which can be actually laborious to pinpoint on each ends of the spectrum. Is that this an influence consumer or a Google spider crawling all of our internet pages for search engine optimisation?” 


JR: “After we assembled the whole lot and it regarded actually good, the following step was getting the info in entrance of the remainder of the crew, which meant constructing a bunch of views in Looker. That was a reasonably large step as a result of that’s once we actually began to iterate, fine-tune and refine our perspective of what was really potential. In some circumstances, we simply wouldn’t have had the info prepared in time to help a few of the unique asks. In different circumstances, we wandered into these actually fascinating pockets of engagement, however they have been so nuanced that we wouldn’t have been in a position to share very a lot about them. It was a really partaking, iterative, backwards and forwards course of to get the whole lot dialed-in till the entire crew was proud of the how issues regarded.” 

Donté: “The information science crew created a Looker dashboard, so we despatched it to the artistic crew, advertising and marketing channel homeowners, and the CRM [Customer Relationship Management] crew. We held a brainstorm with our artistic crew to give you totally different concepts and advertising and marketing activation ways. We used a giant Figjam and talked about how Code Overview may come alive on social media and within the weblog, and the way we’d create some virality and pleasure amongst our learners.” 


JR: “We had individuals on the advertising and marketing aspect desirous about technique and use circumstances, of us on the product aspect experimenting with totally different views on engagement and variations of the undertaking, and we labored intently with advertising and marketing, engineering and CRM to determine easy methods to greatest share.”
