TeachTables lets you create a scheduling and management site for your school. You can add rooms, lessons, groups, teachers, and students, enroll students in groups, assign groups to courses, assign teachers to courses, set up timetables for teachers, create plans for courses, set up tests for courses, and enter information for absent teachers, meetings (visible in timetables), and reservations for rooms/equipment. There is a quiz module with integrated support for numeric questions and symbolic evaluation of answers (pycas on the server).
Server code is node.js, and the client is Javascript (based on jQuery and d3.js).
