Services for Education commissioned Substrakt, my employer to build a SaaS platform for the education sector, following changes in legislation.
The curriculum design, assessment and reporting tool allows teachers to create a sequence of work for pupils and track their progress through the National Curriculum. Headteachers and auditors can see reports of pupil, cohort and whole-school progress in realtime.
The site runs Django 1.6 on AWS, using Elastic Beanstalk to provision and deploy servers in a scalable architecture.
This is one of the most complex projects I've worked on, and has tested my maths skills to the limit. The reports require complex calculations which have to be performed quickly. This means a lot of raw SQL as well as parsing data within Python... and knowing when such jobs should be performed at the database or business-logic level.
The Python code is written entirely by me, with 99% of the interface built by me using Twitter Bootstrap, with design and user-interface work provided almost entirely by Substrakt's Creative Director, Jim Braithwaite.
This video shows how sequences of work are designed, by picking statements from the National Curriculum, and grouping them together, ordering them and providing notes as teaching aids.
This video demonstrates the assessment area, where pupils' progress is marked. Completed assessments can be audited by another person, internal or external to the school.
This video shows the reports that can be generated via the system, which queries data in realtime, via raw SQL queries that have been finely-tuned after months of iteration.
