SCRIPT (Deriyeva, Dannath, Paassen, 2026) implements an intelligent tutoring system for Python programming in a German university context, filling a gap in prior ITS which rarely supported Python.

ITS for programming education with individualized hints, addressing the scarcity of human tutors for practice-intensive coding courses.

SCRIPT: Python Programming Tutor

SCRIPT (Deriyeva, Dannath, Paassen, 2026) implements an intelligent tutoring system for Python programming in a German university context, filling a gap in prior ITS which rarely supported Python.

System Design

  • Context: Large undergraduate programming courses where individual tutor feedback doesn't scale
  • Language: Python (vs. prior ITS focused on Java, C++)
  • Pedagogy: Individualized hints and advice during coding exercises
  • Deployment: Real classroom integration (not just lab prototype)

    • Key Features

    FeatureDescription
    Hint generationContext-aware hints based on code state and error type
    Exercise adaptationDifficulty adjustment based on learner performance
    ScaffoldingGraduated support (from syntax to algorithm design)

    Connection to Broader Programming Education

    SCRIPT addresses a core challenge: practice and extensive exercises are essential in programming education, but human tutors cannot scale to large cohorts.

    This connects to:

  • Collaborative AI Tutoring — ProPACT for pair programming (collaborative variant)
  • Formative Assessment — AI-generated coding exercises with human-in-the-loop validation
  • Agentic Workflows Education — Agentic approaches to coding education (e.g., Claude Code tutor)

    • Research Gap Addressed

    Prior ITS for programming focused on:

  • Java (most common in early CS education research)
  • C/C++ (systems programming contexts)
  • Block-based languages (K-12)

    • SCRIPT's contribution: Python-specific tutoring with German-language context (university-level). Python's dynamic typing and REPL-based workflow require different hint strategies than statically-typed languages.

    Implications

  • Language-specific scaffolding: ITS must adapt to language idioms (Pythonic vs. Java-esque solutions)
  • Classroom integration: Real deployment reveals usability barriers invisible in lab prototypes
  • Scalability: ITS enables personalized feedback without proportional instructor hiring
