AI Teaching Assistant Guide: How to Cut Student Q&A Time by 80%

A practical guide to setting up GlobalClass's AI Teaching Assistant: what it learns from, how to make it more accurate, and how to use it without losing the human touch.

March 5, 20265 min read

Student questions are the hidden tax on a successful course. Every "what does X mean?" or "the link in lesson 3 doesn't work" interrupts your day. The AI Teaching Assistant (AI TA) handles the routine ones automatically — typically cutting Q&A time by 70–80% for a published course.

How the AI Teaching Assistant Works

The AI TA is trained on three sources of content from your course:

  • Video transcripts — auto-generated when you upload videos
  • Lesson descriptions — the text fields under each lesson
  • Supplementary materials — any PDFs, slides, or FAQs you upload

When a student asks a question in the course Q&A panel, the AI searches across these sources, generates an answer with citations, and posts it within seconds. If it's not confident in an answer, it forwards the question to you instead of guessing.

Setup: 4 Steps, About 5 Minutes

  1. Open the AI Agents menu in your dashboard
  2. Select a course and toggle AI TA on
  3. Upload supplementary material (optional but recommended — see below)
  4. Send a test question from the student preview to verify accuracy

Three Tips to Make It Dramatically More Accurate

1. Write Detailed Lesson Descriptions

Lesson descriptions are weighted heavily in the AI's answers. A 2-3 sentence summary per lesson — what's covered, what students will learn — improves answer quality more than anything else.

2. Upload an FAQ as Supplementary Material

If you've taught this material before, you already know the top 10 questions students ask. Upload them as a PDF or markdown file. The AI will cite this directly when relevant.

3. Review the Answer Log Weekly

The dashboard shows every question and the AI's answer. When you spot a wrong or vague reply, edit the source content (lesson description or FAQ) — the AI will pick up the fix on the next question.
