The last question type that we're going to create as part of this training is a numeric question. A numeric question is very similar to the Short Answer question that we created earlier. It allows the students to answer a question by filling in their answer inside of a blank. The differences that in a numeric question, you can set a range of number values within the accepted tolerance that will be accepted as a correct answer. Let's begin by clicking the dropdown menu for Create a new question and selecting Numeric from the dropdown menu. We'll set the Category for this question set to Ecology. We'll then type in the Question name of Numeric.
Inside the Question text, we'll type in 'Hermatypic corals have a very specific temperature range in which they survive. Please list an acceptable average annual sea water temperature (C) where you will typically find coral reefs.' Next, we'll scroll down in the window and set the additional parameters for this question. We do not need to display any images as part of this question, and the Default grade for the question of 1 and a Penalty factor of 0.1, are both fine. We're also not going to provide any General feedback to the student.
Let's go ahead and scroll down to the Answer section. Now corals need a temperature range of between 18 and 32 degrees Celsius as an average annual seawater temperature. This means, if we enter in an answer of 25, for 25 degrees Celsius and we give that a correct answer of 100%, then we would need to add in an acceptable error of 7, meaning that 7+25 is 32, and 25-7 is 18. So Moodle would then give a correct answer for any value that a student enters in between 18 and 32 degrees Celsius.
If you want to provide any feedback, you can do that here. If you scroll down on the window, you could provide additional answers, if need be, that will provide additional ranges of questions and provide a sliding scale for partial credit. However, since corals would not be able to survive with an average annual temperature, we'll leave both of these blank, scroll all the way to the bottom and click on the Save changes button. We can then test the numeric question by clicking on the magnifying glass next to Numeric. We can see that we still have our Hermatypic corals linked as a hyperlink back to their definition. In this case, this definition wouldn't give any additional information to our students, so it may be fine to go ahead and leave it. We'll go ahead and turn that off though in just a second.
Come down to the Answer blank and let's test our answers. So let's begin by answering in a correct answer of 26. We'll hit the Submit button and see that we get full credit. Let's then change the answer to 18, hit Submit. We again get full credit. But what happens if we hit 34? Hit the Submit button and we're not given any credit for this answer. This is considered a wrong answer because it falls outside of the range or a correct answer is 25 +/- 7. Let's go ahead and take care of that Hermatypic corals link.
We'll go ahead and close the Preview window. Then hit the Edit button next to Numeric. We'll select the entire question and click the button for Prevent automatic linking. We'll scroll all the way to the bottom once more, click the Save changes button, preview the question one time to verify that our change took. Now we can see that Hermatypic corals is no longer linked back to the definition inside of our course glossary. We can close the Preview window.
We'll then click the dropdown menu for Category and select Default for Coral Reef Ecology. Now we can see all the different question types that we've explored as part of this training. The next thing we want to do is show you how to import a test bank that's been exported out of a Blackboard quiz from another course.
