Application of Large Language Models for Programming Feedback

Core Concepts

Large language models like GPT-4 can effectively provide feedback in programming education, addressing code errors but requiring further improvements.

Abstract

This study explores the use of large language models, specifically GPT-4, to enhance programming education by providing feedback on tasks without revealing solutions. The research involved developing a web application named Tutor Kai that utilized GPT-4 to generate feedback for 51 students over a semester. Results indicated that most feedback effectively addressed code errors, although challenges with incorrect suggestions and hallucinated issues were identified, highlighting the need for enhancements.
Automated solutions have been developed to address the time-consuming nature of providing feedback in courses with numerous exercises like programming. Large language models such as GPT-4 offer new possibilities in this area, showing high performance in solving introductory and complex programming tasks. While tools like ChatGPT and GitHub Copilot aim to boost productivity, integrating GPT-4 into educational environments can provide timely feedback without giving away solutions.
Existing research compares different models like Codex and GPT-3.5 in generating responses to student help requests or examining responses to incorrect student solutions using ChatGPT. Studies have shown varying levels of success in generating accurate and complete feedback, with challenges related to avoiding providing complete solutions or code consistently.
The evaluation of Tutor Kai demonstrated that GPT-4 could identify most issues in code submissions while minimizing the appearance of code in feedback. Students rated the feedback positively overall, but issues arose with forced rating interfering with task completion and potential data distortion due to students seeking ways to avoid rating.
Future research aims to evaluate different types of feedback generated by LLMs and develop frameworks for automating this process. Anticipated advancements in models like GPT-5 or Llama3 may enhance their ability to formulate code explanations and provide feedback effectively.

Deeper Inquiries

How can the issue of code appearing in LLM-generated feedback be effectively addressed?

To address the issue of code appearing in LLM-generated feedback, several strategies can be implemented. One approach is to refine the prompt given to the LLM by providing more specific instructions on what should and should not be included in the feedback. By clearly outlining that only textual explanations are required without any actual code snippets, the model may adhere more closely to these guidelines. Additionally, incorporating a post-processing step where another AI model checks and filters out any code segments from the generated feedback could help ensure that no unintended code leaks through.

What are the implications of students seeking ways to circumvent rating processes on data accuracy?

When students seek ways to circumvent rating processes for feedback, it poses significant challenges for data accuracy and reliability. If a substantial number of students manipulate or avoid providing ratings, it skews the overall perception of how effective or helpful the generated feedback truly is. This behavior introduces bias into the dataset used for evaluation and analysis, leading to inaccurate conclusions about the performance of LLMs in generating programming feedback. To mitigate this issue, mechanisms must be put in place to incentivize or enforce honest and consistent rating practices among students.

How might future advancements in LLMs impact their application in educational settings beyond programming education?

Future advancements in Large Language Models (LLMs) hold immense potential for transforming educational settings beyond just programming education. With improved capabilities such as enhanced natural language understanding, reasoning abilities, and context retention, advanced LLMs like GPT-5 or other upcoming models could revolutionize various aspects of teaching and learning across diverse subjects. These models could facilitate personalized tutoring experiences tailored to individual student needs, generate interactive educational materials like virtual lectures or textbooks with real-time assistance features based on student queries, and even support automated grading systems for assignments across different disciplines. The increased token processing capacity expected with new models would enable richer contextual understanding within educational content creation and delivery methods.
