In an online Biochemistry class, an instructor is testing students on open response questions that require chemical/mathematical formulas entry. Right now the students' process consists of, writing the equations on a piece of paper, take a photo with their work using their phone and upload the image to canvas. However, this requires multiple uploading/downloading from devices relatively large file sizes and is not convenient.
Writing formulas in words/equation editors is also time consuming and distracts from the contact, since students don't usually use equation editors.
Any thoughts on alternative methods?
