Utilizing Adaptive Learning with GPT-4 for Introduction to Python: Effects on Accuracy and Time-to-Solution

Programming instruction in universities often struggles to adapt to individual needs and sustain motivation. This study presents Code Showdown, a web application that combines adaptive learning with GPT-4 to strengthen Python programming skills through automatically generated challenges and immediate personalized feedback. The development followed four phases: (i) selecting the pedagogical approach, (ii) choosing the language model, (iii) integrating GPT-4 for challenge generation and formative feedback, and (iv) building a scalable web architecture. The proposed approach was evaluated with 40 undergraduates (two groups of 20 individuals) over two weeks. Group E1 studied with traditional resources, whereas Group E2 used Code Showdown in individual and multiplayer modes. Using explicit metrics—Improvement Score (IS, %) and Improvement in Response Time (IRT, %)—Group E2 achieved higher means across difficulty levels: IS of 18.9±4.2% (Easy), 40.7±4.7 % (Intermediate), and 58.6±5.1 % (Hard), and IRT reductions of 32.4±6.3%, 28.0±5.8%, and 28.3±6.1 %, respectively. A t-test showed that these differences were statistically significant (p
