Answers and explanations appear as you take the quiz.

1. What does 'knowledge tracing' estimate in an intelligent tutoring system?
   • The probability that a learner has mastered each particular skill
   • The student's favorite subject
   • How fast the internet connection is
   • The teacher's salary
2. What is the defining feature of a Socratic tutoring approach, as used by tools like Khanmigo?
   • Immediately giving the final answer to save time
   • Guiding the student with questions rather than revealing the answer directly
   • Refusing to help with any questions
   • Only teaching ancient Greek philosophy
3. The 'zone of proximal development' that good tutors aim for describes tasks that are:
   • Far too easy and boring
   • Impossibly hard for the learner
   • Challenging but achievable with appropriate support
   • Completely unrelated to the subject
4. What does spaced practice do to the timing of review?
   • It removes all review after the first lesson
   • It presents every item only once
   • It schedules all practice in one continuous block
   • It distributes practice or review sessions over time rather than massing them together
5. In a randomized study of 252 learners receiving math tutoring feedback, what happened as erroneous feedback became more common?
   • Perceived usefulness of the feedback declined
   • Every learner’s test score rose by the same amount
   • Learners stopped using the tutoring system entirely
   • The study found no relationship with perceived usefulness
6. Which is a defensible design option when a tutoring system suggests practice for a learner?
   • Assume the software’s plan is correct for every learner
   • Let a teacher review or adjust the suggested practice when appropriate
   • Remove teachers from all instructional decisions
   • Treat engagement as proof that learning improved
7. In Bayesian Knowledge Tracing, what does the guess parameter represent?
   • The chance a mastered skill is forgotten between opportunities
   • The probability a tutor chooses the next worksheet
   • The chance a learner answers correctly despite not having mastered the skill
   • The time required to complete a course
8. What does BKT’s learning-transition parameter represent?
   • The probability that a question is mislabeled
   • The chance a learner guesses correctly without mastery
   • The proportion of lessons using video
   • The probability that an unmastered skill becomes mastered between practice opportunities
