The Image Label Question block lets learners type labels on images and diagrams. Learners see input fields positioned over the image and must enter the correct labels for each marked location. Learners view an image with text input boxes at specific positions and type their answers. Their responses are automatically marked against your specified correct answers.
For demonstration purposes where learners just view labeled images without assessment, use the Image Label block instead.

When to use Image Label Question blocks

Image Label Question blocks work well for:
  • Testing vocabulary knowledge with visual cues
  • Assessing understanding of diagrams, maps, or scientific illustrations
  • Checking knowledge of anatomy, geography, or technical components
  • Evaluating ability to identify parts, features, or locations
  • Testing recall of names, terms, or classifications

Tips for teachers and parents

Best practices:
  • Use clear, unambiguous images where features are easily identifiable
  • Position input boxes to avoid covering important image details
  • Provide sufficient space for learners to type their answers
  • Test your questions to ensure answers are reasonable and fair
  • Use appropriate vocabulary level for your learners
  • Consider providing scaffolding with partial prompts when helpful
Creating effective questions: For vocabulary assessment:
  • Use images that clearly represent the target vocabulary
  • Position input boxes near the relevant image features
  • Accept reasonable variations in spelling and terminology
  • Consider both common and technical terms as correct answers
For scientific diagrams:
  • Use accurate, detailed diagrams appropriate for the grade level
  • Include both structure names and function descriptions where relevant
  • Test essential vocabulary that learners should know
  • Provide clear anchor points to specific diagram features
For geography and maps:
  • Use clear, readable maps with distinct features
  • Test significant geographical features, cities, or landmarks
  • Accept common spelling variations and alternative names
  • Position inputs to avoid overcrowding the map
For anatomy and biology:
  • Use appropriate anatomical illustrations for the age group
  • Focus on essential structures learners should identify
  • Accept both common and scientific terminology
  • Group related structures logically
Answer setup strategies: Flexible marking (recommended for most cases):
  • Accommodates minor spelling errors and variations
  • Accepts different capitalization patterns
  • Handles extra spaces or punctuation differences
  • Good for vocabulary and general knowledge questions
Exact marking (use when precision matters):
  • Requires precise spelling and formatting
  • Useful for testing specific terminology
  • Appropriate for advanced learners or technical subjects
  • Good for assessment situations requiring strict accuracy
Multiple acceptable answers:
  • Include common synonyms or alternative terms
  • Accept both abbreviated and full forms (e.g., “USA” and “United States”)
  • Consider regional variations in terminology
  • Include both scientific and common names when appropriate
Question design tips:
  • Start with easier, more obvious labels before moving to challenging ones
  • Mix familiar and new vocabulary appropriately
  • Use consistent input box sizing throughout the question
  • Test your questions with sample learners when possible
  • Provide clear instructions about expected answer format
