6.2 Skill-Based Targeting
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 delivery types. Each serves a different instructional purpose.
Linear Questions are delivered in a fixed order. Every student who takes this problem set will see the same questions in the same sequence. 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 are shuffled each time the problem set is taken. Two students sitting next to each other will see the same questions but 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 problem set is divided into sections. Based on how a student performs in the first section, EdisonOS automatically determines which version of the second section they receive either an Adaptive Upper (more challenging) or Adaptive Lower (more supportive) set of questions.
Adaptive problem sets are the most powerful for personalised learning. They mirror the structure of adaptive standardised tests like the digital SAT and give students the most accurate practice experience. Use this type when the skill being assessed spans a wide difficulty range.
