This article explains to students what they need to be aware of when writing multiple attempt quizzes, or adaptive mode quizzes.
In Moodle, tests can be constructed in a such a way that students will be given multiple attempts to complete an exam. The number of attempts and how those attempts will be graded are specified in the introduction area of the exam. An example is posted below.
Note that this particular example shows that the student is being given 3 attempts to complete this quiz, and that when the quiz is graded, the attempt that achieved the highest grade will be used. Other grading options include using the lowest grade, the last graded attempt, or an average of the attempts.
In many cases when you attempt a quiz for a second or multiple time, the quiz will be a fresh blank quiz for you to complete.
However, some quizzes have the ability to enable adaptive mode. What this means is that the instructor can specify that when you answer a question, you are allowed to try that question multiple times before moving on to the next question in the quiz. You can tell it is an adaptive mode question because the question will contain a submit button.
When answering these questions, there is a save, next and a submit button available. It is important to note what these buttons do. The submit button is the most important. By clicking submit, you are actually submitting your answer to the question. Save makes sure that your "submitted" answer is saved in Moodle's short term memory. The Next Button will navigate you to the next question in the list.
Instructors can also create quizzes that utilize adaptive mode, AND implement penalties each time you submit an answer for a question. For example you could answer question one on your quiz by choosing the letter B and hitting submit. If you choose to change your answer to A and then click Submit again, Moodle notes this answer change and logs it as an attempt on the question. If penalties are active in an adaptive mode quiz, upon hitting submit for the second time you will be notified of the penalty for answering again.
If a question is worth one mark, and the penalty factor for answering it wrong each time is .25 marks, you only have the ability to answer the question wrong 3 times before you receive 0 for the question. If you take 2 attempts to get the right answer, even though you got the right answer eventually, you lose .25 x1 for the 1 other wrong answers you provided before the correct answer. In this particular case you would only receive .75/1 for that question.
One other feature that instructors can add to their quizzes is the ability for the students to build on previous attempts of a quiz. If you are writing a quiz that has multiple attempts, your instructor may specify that on the next quiz attempt your answers from the previous attempt are visible within the quiz. If you answered B for question one, on the next attempt it will seem that B is selected for that question.
IMPORTANT: This does not mean that the question is answered. You will need click Submit to re-submit the answer for that question before clicking Next. If you do not re-submit the questions, when you click to finish and submit the exam, the questions you did not re-submit will appear as unanswered; even though visually it appears that the question is answered.
Building on previous attempts only overlays your previous answers and does not automatically count them as submitted answers. Clicking save on these questions does not re-submit the answer. Only clicking Submit will make the question be recognized as an answered question.
