The 4I Model of Benefits and Its Integration with the Technology Acceptance Model (TAM): Teenagers’ Perspectives on Using ChatGPT for Homework

The introduction of ChatGPT has provided students with a tool similar to a fairy-tale djinn, giving the ability to simplify homework and projects with just a few keystrokes. This study examines teenagers' perspectives on using ChatGPT for homework, exploring both the perceived benefits and concerns. Based on content analysis of responses from 141 teenagers aged 14 to 16 from grammar schools across various federal regions in Germany, we introduce the 4I Model of Benefits, identifying four key advantages: Information, Inspiration, Improvement, and Immediacy. Integrated within the Technology Acceptance Model (TAM) framework, this model clarifies factors influencing teenagers’ acceptance of AI text generators in education. Findings indicate that, while most teenagers recognize the distinct benefits of using ChatGPT, concerns about learning efficacy and over-reliance underscore the need for balanced educational integration. By enriching the TAM framework, the 4I Model identifies the specific benefits of ChatGPT that drive its acceptance and provides valuable insights for educators, policymakers, and developers.
