Learning environments that run smoothly, by default

Houghton Mifflin Harcourt

 Houghton Mifflin Harcourt is a global leader in educational publishing, delivering the right digital learning materials at the right time to children in all grade levels across the US, every day.

To make sure it happens without a glitch, HMH partnered with us at Reaktor to build a system that keeps data flowing and eliminates several thousand hours of manual work each year. 

Course enrollments through the application

Digital
 experiences are a part of everyday learning. Delivering the right 
experience at the right time to each individual student is a crucial 
part of a modern publisher’s job.

To make it happen, district, school, class, and student 
data must be accurate, up to date, and in the right place. With 55.6 
million students starting school simultaneously, variable systems, 
standards, and formats&nbsp;make it a complex problem.

Together, our team and HMH tackled the 
colossal amount of data by building an application that makes the data 
flow automatic. It collects everything needed from companies providing 
rostering information and automatically pushes it to HMH’s platforms. 

 The application removes the burden of 
data entry, roots out faulty and expired data, and eliminates the 
possibility of human error.

School
 districts give out their data at the end of July and new digital 
solutions need to be in use by the month of August. We started 
developing the app in February 2016, and HMH was aiming to have it in 
full use by the back-to-school season of 2017.

Our team had the software up and running in two months and the first 
end-to-end automatic rostering of information was completed a year 
early.

 Now, after iterative improvement of 
usability and data revision procedures, HMH’s products run smoothly and 
disruption-free for students in 50 states.

Node.js
 JavaScript runtime was selected specifically for enabling quick 
development, and for its ability to handle I/O bound workloads. 

 For the backend, we went functional and reactive with Bacon.js, and used Bluebird for speedy promise handling. 

 The user interface deploys React with Calmm architecture, and concepts such as lenses, atoms and observables.
