Use Case: Using AI Lesson Generation

Go to your course, click "Add Lesson", then select "AI Generate". Alternatively, access the AI generator from "Tools" -> "AI Generation" in the sidebar.

Select Target Language

Choose the language you are teaching (e.g., Spanish, French, German). This determines the language of generated content and exercises.

Set CEFR Level

Select the proficiency level. The AI adjusts vocabulary complexity, sentence length, grammar scope, and exercise difficulty accordingly.

Enter Topic

Type your topic in the text field. Be specific:

Good: "Preterite tense of regular -AR verbs with daily activity vocabulary"
Too vague: "Past tense"
Too broad: "All Spanish verb tenses"

Configure Options

Content type: Grammar, Vocabulary, Conversation, Mixed
Exercise types: Select which exercise formats to include
Lesson length: Short (15 min), Medium (30 min), Long (45+ min)
Additional instructions: Free-text field for special requests (e.g., "Include a dialogue at a restaurant", "Focus on irregular forms")

Generate

Click "Generate Lesson". The AI processes your request (typically 30-60 seconds). A progress indicator shows the generation status.

Step 3: Review the Raw Output

The AI produces a complete lesson in the Lex Editor format. Before doing anything else, read through the entire output:

Check for:

Factual accuracy (grammar rules, translations, conjugations)
Appropriate difficulty for the target level
Natural-sounding example sentences
Exercise quality and answer correctness
Cultural sensitivity and appropriateness

Always verify AI-generated content before sharing with students. The AI occasionally produces incorrect translations, awkward phrasing, or exercises with ambiguous answers. A 10-minute review can prevent confusion in class.

Phase 3: Customizing the Lesson

Step 4: Edit and Personalize

Open in Lex Editor

The generated lesson opens directly in the Lex Editor. You can edit everything -- text, exercises, structure, formatting.

Fix Any Errors

Correct inaccurate translations, grammar explanations, or exercise answers. Pay special attention to:

Irregular forms the AI may have regularized
Cultural context that may not apply to your students
Vocabulary that is too advanced or too simple for the level

Add Your Teaching Voice

Replace generic explanations with your own style:

Add mnemonic devices you use in class
Include references to previous lessons
Insert personal anecdotes or cultural insights

Reorganize If Needed

Move sections around to match your preferred lesson flow. You might want to:

Lead with a dialogue instead of grammar rules
Group exercises differently
Add a warm-up activity the AI did not include

Add Media

Enhance the lesson with:

Images for vocabulary items
Audio recordings for pronunciation
Links to supplementary resources

Step 5: Test the Exercises

Go through every exercise as if you were a student:

Answer each question yourself
Verify the correct answer is truly correct
Check that wrong options are plausibly wrong (not obviously absurd)
Confirm fill-in-the-blank accepts reasonable alternative answers
Test sentence builder pieces for logical assembly
Verify matching pairs are accurate

The AI sometimes generates multiple-choice distractors that are too obviously wrong or too close to the correct answer. Adjust distractors so they test real understanding rather than guessing ability.

Phase 4: Saving and Using

Step 6: Save and Publish

Preview the Lesson

Click "Preview" to see the lesson exactly as students will see it. Check layout, readability, and exercise interactivity.

Save to Course

Click "Save" to add the lesson to your course. Set the lesson type (Class Lesson, Exercise Set, or Homework).

Set Lesson Order

Drag the new lesson to the correct position in your course outline.

Publish

If the lesson is ready for students, ensure it is visible. If you want to hold it back, keep it in draft status.

Step 7: Track in Generation History

Every AI generation is saved in your Generation History. This lets you:

Revisit previous generations
Reuse successful prompts
Compare different generation attempts
Track your token spending on AI generation

Workflow Tips

Batch Generation Strategy

Generate multiple lessons in one sitting:

Prepare briefs for 5-10 lessons
Generate all of them back-to-back
Let them sit overnight
Review and edit with fresh eyes the next day
Publish the batch

If the first generation is not quite right:

Adjust your prompt and regenerate (costs another 100 tokens)
Or manually edit the existing output (free, often faster)
Save successful prompts as templates for future use

Building a Prompt Library

Keep a document of prompts that produced good results:

PROMPT: "Create an A2 Spanish lesson on reflexive verbs
used in daily morning routines. Include a dialogue between
two roommates, vocabulary list with 15 reflexive verbs,
3 multiple-choice exercises, and 2 sentence-builder exercises.
Tone should be casual and fun."

RESULT: Excellent. Used as-is with minor edits.

Common Generation Scenarios

Vocabulary-Focused Lesson

Prompt tips: Specify the theme, number of words, whether to include images/audio placeholders, and exercise types. Example: "20 food vocabulary words for A1 French with matching exercises and a fill-in-the-blank dialogue at a cafe."

Grammar Explanation Lesson

Prompt tips: Name the specific grammar point, request a comparison with the students' native language if relevant, and ask for both rule explanation and practice exercises. Example: "German dative case with prepositions, compare to English, include 5 fill-in-the-blank and 3 multiple-choice exercises."

Conversation Practice Lesson

Prompt tips: Describe the scenario, the roles, and the target language functions. Example: "B1 English lesson: booking a hotel room by phone. Include a model dialogue, key phrases list, and role-play prompts."
