During an instruction session in a physical classroom, teachers often ask questions to the students in class. Since students in an online classroom are not co-present in the same location at the same time, online teachers do not face the constraint of needing to select individual students to answer a question. This disclosure describes virtual classroom assistant functionality that enables teachers who deliver online instructional content to pose questions to the set of students participating in an instructional session. The functionality can include delivery of questions to the students, collection and processing of their answers, and generation grades and feedback with or without the teacher’s assistance. Further, additional questions can be generated or selected based on student performance on previous questions.
