I recently discovered that I could assign my students a "worksheet" style assignment that they could complete using the the cloud-based external tool option (Office 365). However, I have several students who complete the work, but when they try to submit the work all they are submitting is a blank document. I am perplexed as to why this is occurring and I have not been able to find any threads on this topic, other than how to assign a cloud-based assignment. For some students, I thought it was because they did not complete the assignment in one sitting, but returned back to their work later, but I no longer think this is the reason why their work is submitted blank. Any thoughts?
