Using the Living Canvas

The Living Canvas is Loka's interactive whiteboard -- the core of every lesson. It captures everything that happens during a session: notes, vocabulary, corrections, and teaching moments. Think of it as a living document that grows with each lesson.

What Is the Living Canvas?​

Unlike a static whiteboard that gets erased after class, the Living Canvas persists. Every note, keyword, and correction is saved automatically and becomes part of the student's learning record. Over time, it builds into a personalized textbook -- the Living Textbook -- unique to each learner.

Starting a Session​

  1. From your dashboard, click Start Session
  2. Select the student and service type
  3. The Living Canvas opens in a new view, ready for your lesson

Starting a session requires an active Loka Creator subscription. If you see a message about purchasing a seat, check your subscription status.

Canvas Features​

Drawing and Typing​

Use the canvas toolbar to:

  • Type text -- click anywhere on the canvas and start typing
  • Draw freehand -- sketch diagrams, highlight connections, or annotate
  • Add sections -- organize your canvas into logical blocks

Keywords​

Record important vocabulary and phrases as keywords. These are tagged and searchable, making it easy for students to review specific terms after the lesson.

Active Recall Pairs (ARPs)​

ARPs are question-answer pairs that reinforce learning through active recall:

  • Add an ARP by entering a prompt (e.g., "How do you say 'thank you' in Japanese?") and the target answer
  • ARPs are stored in the student's profile for spaced repetition review
  • AI features can auto-generate ARPs from your lesson notes

Correct and Incorrect Phrases (CIPs)​

Mark language as correct or incorrect during the lesson:

  • Incorrect phrase -- what the student actually said
  • Correct phrase -- the corrected version

CIPs are the foundation of the Living Textbook methodology. They capture real moments from conversation and turn them into personalized learning material.

Auto-Save​

The canvas saves automatically as you work. You never need to worry about losing your notes -- everything is persisted in real time.

Exporting Your Canvas​

After a session, you can export the canvas in two formats:

PDF Export​

Generate a clean, printable PDF of the session canvas:

  1. Open the canvas for the completed session
  2. Click the Export menu
  3. Select Download PDF

The PDF includes all text, keywords, ARPs, and CIPs from the session.

MP3 Export (Text-to-Speech)​

Convert your canvas text into an audio file using AWS Polly:

  1. Open the canvas for the completed session
  2. Click the Export menu
  3. Select Generate MP3
  4. Choose the target language and voice
  5. The MP3 is generated and available for download

This is particularly useful for pronunciation practice -- students can listen to correct phrases on the go.

팁

MP3 exports work best when your canvas text is clean and well-structured. Use keywords and CIPs rather than freehand notes for the clearest audio output.

Canvas History​

Every session canvas is saved and accessible from the Canvas tab on your dashboard. You can:

  • Browse past sessions by date or student
  • Reopen any canvas to review or continue adding notes
  • Track a student's progress over time by reviewing their canvas history

Tips for Effective Canvas Use​

  • Structure your canvas -- use sections to separate vocabulary, grammar, and conversation topics
  • Record CIPs in real time -- capture corrections as they happen, not after the lesson
  • Add ARPs for key takeaways -- focus on the 3-5 most important things from each session
  • Export after every lesson -- send students a PDF or MP3 so they can review independently
