Inspiration

We were inspired by the challenge of making eLearning more interactive and effective while maintaining learner privacy. Evaluating open-ended questions has always been difficult, especially in real-time and offline scenarios. The introduction of Chrome’s built-in AI features presented a unique opportunity to solve this problem and revolutionize how courses engage learners.

What It Does

The AI-Powered Question Scorer evaluates open-ended learner responses directly in the browser using Chrome’s built-in AI. It compares the response against pre-defined criteria, provides a score, and explains the reasoning—all without requiring an internet connection. This ensures data privacy and allows for seamless offline functionality.

How We Built It

  • We created the course structure in Articulate Storyline, including a slide for learner input and a results display.
  • JavaScript was used to integrate with Chrome’s Gemini Nano AI APIs.
  • A system prompt was crafted to guide the AI on evaluating responses, scoring them based on pre-defined criteria, and returning output in JSON format.
  • Storyline variables were updated dynamically based on the AI's output to display results in real-time.

Challenges We Ran Into

  • Handling AI Output: The AI occasionally returned responses in unexpected formats like Markdown or incomplete JSON. We addressed this with robust error-handling and filtering.
  • Prompt Design: Balancing clarity and brevity in AI instructions to achieve consistent and accurate evaluations was a significant challenge.
  • Early Access Limitations: Since the Chrome AI tools are in preview, accessing and testing the features required jumping through technical hoops.

Accomplishments That We're Proud Of

  • Successfully implemented a fully offline AI-powered scoring system for open-ended responses.
  • Maintained strict data privacy by ensuring learner input never left the browser.
  • Streamlined the integration between Articulate Storyline and Chrome’s AI, demonstrating the potential of combining modern browser tools with eLearning platforms.

What We Learned

  • The importance of crafting detailed yet concise AI instructions for consistent results.
  • How to effectively use Chrome’s AI tools and adapt to their quirks during the development phase.
  • New possibilities for making eLearning courses more interactive, personalized, and secure using browser-based AI.

What's Next for AI-Powered Question Scorer

  • Enhanced Scoring Criteria: Adding more granular and customizable scoring options for different question types.
  • Broader Integration: Extending the solution to work with other eLearning platforms like Moodle or Canvas.
  • User Feedback Loop: Incorporating feedback from educators and learners to refine the scoring model further.
  • Advanced Analytics: Building a dashboard to visualize learner performance trends and insights in real-time.
  • Public Availability: Collaborating with Chrome’s team to make this tool accessible to the broader eLearning community once the AI features are officially released.
