TLDR: MazeMate is an AI chatbot integrated into a 3D maze game that helps university students learn computational thinking skills like problem-solving and algorithmic design. It provides adaptive, context-aware support for both solving and creating mazes, using a staged approach to prevent students from simply copying answers. A study with 247 students found it moderately helpful, especially for maze solving, though it faced challenges with creative design tasks and sometimes gave irrelevant suggestions.
Computational Thinking (CT) is a vital skill for problem-solving in our modern, data-driven world. It involves breaking down complex problems, recognizing patterns, abstracting ideas, and developing step-by-step solutions. To help students cultivate this skill, gamified programming environments like Scratch and 3D Maze have become popular, offering interactive challenges that make learning accessible and engaging.
While these environments provide a great starting point, research shows that students often need additional support, or ‘scaffolding,’ to truly master CT. Traditional scaffolding can be rigid, unable to adapt to a student’s unique progress. The rise of large language models (LLMs) like ChatGPT offers new possibilities for adaptive and contextualized support in education. However, current LLM applications often fall short in fostering the full CT process, sometimes even encouraging students to take shortcuts by simply copying AI-generated solutions.
Introducing MazeMate: An AI Companion for Learning
To address these challenges, researchers have developed MazeMate, an LLM-powered chatbot seamlessly integrated into a 3D Maze programming game. MazeMate is designed to provide intelligent, context-sensitive guidance that aligns with the core stages of computational thinking, both when students are solving mazes and when they are designing them.
MazeMate stands out with four key design features:
- Contextual Awareness: It understands the specific rules and elements of the 3D Maze environment, providing relevant feedback.
- Adaptive Support: It synchronizes with real-time game data, adjusting its guidance based on a student’s current progress.
- Accurate Solutions: For complex maze-solving tasks where LLMs might ‘hallucinate’ or provide incorrect logic, MazeMate integrates sophisticated path-finding algorithms. This ensures that any solution hints it provides are accurate and valid within the game’s constraints.
- Progressive Scaffolding: To prevent students from using it as a shortcut, MazeMate reveals answers gradually. For instance, if a student asks for a solution, it first offers a ‘low-efficiency’ step-by-step path, encouraging them to decompose the problem. Only after further interaction and attempts to abstract patterns does it provide a ‘high-efficiency’ algorithmic solution.
How MazeMate Supports Computational Thinking
MazeMate’s scaffolding is carefully aligned with the CT process and classroom lesson plans:
- Maze Solving: In this logic-intensive activity, MazeMate helps students decompose complex mazes into smaller, manageable steps. It then guides them to recognize repetitive patterns and abstract them into efficient code blocks like loops and conditionals. Finally, it assists in synthesizing these insights into a high-efficiency algorithmic solution.
- Maze Design: For this creative, open-ended task, MazeMate helps students decompose their design ideas by checking if they meet requirements (e.g., number of monsters, gems). It also uses its path-finding algorithm to verify if a designed maze is actually solvable. It encourages pattern recognition by linking structural features of the maze (like junctions or U-turns) to algorithmic expressions. Ultimately, it helps students connect their designs with the necessary code blocks for a high-efficiency solution.

Real-World Impact and Future Directions
A study involving 247 undergraduate students revealed that MazeMate was perceived as moderately helpful, with slightly higher usefulness for maze solving compared to maze design. Students reported that MazeMate effectively supported decomposition by breaking down problems, aided pattern recognition by simplifying repeated steps, and assisted algorithmic thinking through debugging and providing correct algorithms.
However, the study also highlighted areas for improvement. In maze design, students sometimes received ‘mismatched suggestions’ or ‘fabricated algorithm solutions,’ especially when attempting highly creative or unusual designs. This suggests that while MazeMate excels in structured, logic-intensive tasks, it faces challenges in open-ended creative scenarios where LLMs are more prone to generating less accurate or relevant outputs. The progressive scaffolding, while pedagogically sound, sometimes conflicted with students’ desire for immediate, direct answers, leading some to abandon AI assistance if the solution wasn’t instantly provided.
The findings underscore the potential of LLM-based chatbots like MazeMate to enhance computational thinking education. Future refinements will focus on improving MazeMate’s contextual understanding in creative tasks, strengthening its ability to elicit reasoning from students, and finding a better balance between staged guidance and student expectations for direct support. This ongoing work aims to ensure that AI-supported learning environments can truly foster deeper problem-solving skills for the 21st century. You can read the full research paper here.
