6.2 Type of Problem Set
Updated 7 days ago
The core purpose of a problem set is to target a specific skill gap. EdisonOS gives you structural tools through problem set types to control how questions are delivered and how difficulty adapts to each student.
Problem Set Types
When creating a problem set, you must select one of three types. Each serves a different instructional purpose.
Linear Questions generally follow the configured order. Student exposure history is prioritized before the configured question order, so it can affect which questions are selected and the order they appear in. Best for structured, teacher-directed practice where consistency matters.
Use Linear when you want full control over the question order for example, scaffolding from easier to harder questions deliberately.
Random Questions use student-specific ordering based on a stable per-student hash plus exposure history, so attempts can vary between students and between takes. When the eligible pool of questions exceeds the requested count, students may receive different question subsets, not just the same questions in a different order. This discourages answer sharing and keeps repeat attempts fresh.
Random is ideal for homework or independent practice where you want to reduce the chance of students copying from one another.
Adaptive (Question Adaptive) The difficulty of each question is determined by the student's performance on the previous question. Based on whether a student answers correctly or incorrectly, EdisonOS automatically adjusts the difficulty level of the next question, providing a more personalized assessment experience. Students who perform well receive more challenging questions, while those who need additional support receive questions better suited to their current skill level.
Question Adaptive tests adjust the difficulty of each question based on the student's previous response, creating a personalized assessment experience.
