| Matching interaction | Three selection fields replace dragging elements onto the image. | Complete using a keyboard, mouse or touch. |
| Link to the figure | Numbers 1, 2 and 3 also appear in the fields and text description. | Check that the figure, instructions and answers correspond. |
| Answer key | 1: evaporation; 2: condensation; 3: precipitation. | Test correct, incorrect and partially correct responses. |
| Attempts and feedback | Retry is allowed. Each stage receives an explanation after checking. | Empty fields do not count as a complete attempt; changing a response clears previous feedback. |
| Access to content | Vector illustration with a text description available. | Check legibility, labelled fields and keyboard operation. |
| LMS integration | This demonstration is not connected to an LMS. | In a real project: validate persistence, scoring and completion in the client’s environment, within the agreed scope. |
