Essay questions are perhaps the easiest of the questions to create. These questions allow you to see what the student knows or feels about the question. One of the drawbacks to using Essay is that they require you to read each response individually and manually score them, something we will talk more about later.
Some people use Assignment to give essay questions. Assignment allows you to create essay questions in a faster, easier, and many say, better way. However, if it does have a place in your quizzes, that place is for when you want to time your students' writing, and this is something that can't be done with Assignment.
When creating Essay questions, it is important to clearly tell the students what you are looking for in the response. How many words you are looking for, that they must follow a specific essay format, and so on. If you are able to clearly spell out these types of things, the Essay format will be a valuable addition to your tests.
