Inq-ITS (Inquiry Intelligent Tutoring System) is an online educational environment for science. Inq-ITS puts students in control of their own learning by leading an authentic inquiry experience through our NGSS-aligned virtual labs. As students work, Inq-ITS uses patented algorithms that automatically assess students and generate real-time reports on classroom-wide and student-specific performance for educators. Teachers also receive real-time alerts as to which students need assistance and on what skills. Rex, an AI virtual tutor, can also help students in real-time as they move through the virtual labs.
