Motivation: AI-based tutoring systems are increasingly common in K-12 classrooms and are proved to be effective for increasing students’ outcome. However, as teachers using the intelligent tutoring systems in classroom sometimes expressed not perfectly satisfied some instructional materials in the systems, as not helpful enough for assisting students’ learning. Teachers expressed desire to customize the materials, yet are short of the time to do so, thus, we seek to improve teachers’ satisfaction without imposing too much on their time, and explored a combination of teachersourcing and crowdsourcing for the instructional materials improvement.
