Enable Show My Work
You can enable Show My Work to let your students explain the reasoning behind their answers on assignment questions.
When you enable Show My Work for a question, your students can enter formatted text and math expressions in the Show My Work answer box. They can also upload files, such as digital images of a whiteboard or paper sketch, a wordprocessing document, or a graphic created with a drawing application.
You or your teaching assistant can then review each of your students' Show My Work responses and add comments or change the questionpart scores based on the completeness or correctness of the work shown. You can award points for optional Show My Work responses, for example, if a student demonstrates understanding of the problem but makes a mathematical error.
You can set Show My Work as Required, Optional, or Disabled.
