Description

Hints are partial prompts or cues that help learners continue a task without fully giving away the answer. They are useful when the design goal is to preserve productive struggle while reducing the chance of stuckness, confusion, or abandonment.

Design Implications

Context

Requirements

• A task learners can still attempt: Hints are most useful when learners retain meaningful work to do.
• Graduated support: Strong implementations move from light cueing to more explicit help only as needed.
• Alignment to the misconception or step: Hints need to target the actual obstacle.

Constraints

• Over-helping: Hints that reveal too much can bypass learning.
• Weak targeting: Generic hints frustrate learners if they do not address the real issue.

Target Learners

• Learners who are engaged but temporarily stuck on a problem, procedure, or draft move.

Target Learning Goals

• Maintain momentum while supporting independence and strategy use.

Affordances

• Scaffolding and Fading
• Immediate Feedback
• Guided Practice

Claims

• K-12 learners preferred incremental hints and multiple attempts over immediately revealed solutions [+W]
• GPT-4 generates targeted corrective feedback for 66% of student errors, but 35% of hints are too general, incorrect, or give away the answer [~W]
• Advanced students showed reduced attempts with all hint types, while novices did not clearly benefit and made slightly more submissions with Single-Issue Feedback [~W]
• Learning gains showed significant main effects of hint condition and subject, with no significant condition-by-subject interaction [~W]
• Persistence and performance costs concentrate among participants who used the AI to obtain direct solutions, while hint-users resemble controls [+W]
• Learning gains from ChatGPT-generated hints were not statistically significantly different from human tutor-authored hints, though ChatGPT gains were numerically higher in all subjects [~W]
• Low-performing students access solutions more often than higher-performing students, while hint access does not differ across quartiles [~W]
• Stimulus and phonemic cues did not notably help adult struggling readers name objects on the BNT [-W]
• Hint Factory MDP-generated hints gave correct next-step hints over 80% of the time and a pilot showed students solved more logic proofs with hints [+W]
• Feedback effects on time to solution did not differ significantly between novice and advanced students, though predicted trends suggest feedback was more beneficial for advanced students [~W]
• Students incorrectly considered partially hinting images helpful [~W]

The evidence by question

• Do hints during practice improve learning over no hints, and do AI-written hints work as well as tutor-written ones? Learners receiving ChatGPT-generated hints showed statistically significant learning gains compared to a no-hint control in an online mathematics tutoring experiment [+M]
• Should help stop at a hint rather than give the solution, and what happens when learners can get the answer directly? Persistence and performance costs concentrate among participants who used the AI to obtain direct solutions, while hint-users resemble controls [+M]

Patterns That Use This Element

• Mastery Learning
• Game-Based Mastery Learning (e.g., Duolingo Pattern)

Examples

• A tutoring system offers a first hint that points to the next subgoal, then a later hint that shows the relevant formula.
• A writing teacher gives a prompt about evidence quality instead of rewriting the paragraph for the student.
