Basic Guide to Question Creation with WirisQuizzes

If you are new to WirisQuizzes, this is the best starting point to familiarize yourself with the different options and the interface. We will guide you step by step through several common use case examples.

Sum of two fractions

In the last years of primary school, the students learn to operate fractions. Let us see how we create a question with WirisQuizzes step by step asking, for instance, for the sum of two fractions. The grading will be done automatically, and for now, both simplified and not simplified answers will be counted as correct.

Select the question type

First, we need to select which type of question we will use. Among all the possible options, the best one for adding two fractions is Short answer because we expect the student to answer with just the result.

Moodle panel where we select the WirisQuizzes question type; Short answer - science in this case

Write the statement

Second, we will write the statement of the problem. Let us ask the students to sum 14\frac14 and 54\frac54. Fractions can be written with MathType

Statement of the sum of two fractions question with the formulas being introduced via MathType

Write the correct answer

Third, open WirisQuizzes Studio by clicking quizzes_studio_4.png.

Note

WirisQuizzes Studio is the main workspace. Here we will provide the correct answer and some matching criteria regarding the form of the solution. For instance, in the next example, we will see how to set the question so that only simplified fractions are correct. You can find more detailed information about WirisQuizzes Studio in its dedicated page.

WirisQuizzes Studio main page

Here you can provide the correct answer to the question.

Preview the question and save the changes

It is always a good practice to test how they behave using the Test this question section, even with simple questions. We can check that all the correct answers the student may provide are indeed correct.

Once you have finished testing the question, go back to the home page and click wiris_quizzes_save.png to save changes and WirisQuizzes Studio window closes.

The view on this tab is the same as the students will have. Since they will see the same math editor that we see, we must select Math editor embedded or Math editor in popup on the Input options section.

Assign full grade and save the question

Finally, we must assign the full grade to the correct answer and save the question by clicking Save changes and continue editing. This way, we will save the question, but we will be left on the same page.

Note we do not require the answer to be simplified. We'll look at how to do that in the next exercise.

Sum of two fractions: simplified answer

Based on the previous question, now we want to go a step further: now it is not only sufficient to compute the sum of two fractions, but it should also be simplified. For instance, only 32 would have been the correct answer in the previous question.

Select the question type

First, we need to select which type of question we will use. Among all the possible options, the best one here is Short answer because we expect the student to answer with just the result.

Validation of the question's correct answer from the student's point of view

Tip

It is possible to create a second answer so that if a student were to answer 64 \frac64, they would get, for instance, half of the score. The same idea is used in this example we will visit later. Try it yourself when you finish this tutorial!

Sum of two random fractions

Imagine you want to include this question on a quiz. All the students will see the same question with the same fraction! Wouldn't it be nice to have one different question for each student? Well, this is possible with WirisQuizzes with a simple command.

The idea is to generate four random numbers that will be the numerators and denominators of our fractions. Every time a student opens the question, different numbers will appear in the statement.

And what about the correct answer? Do we need to assign to each possible case its correct answer? Of course not! We will treat fractions as variables, perform their sum inside CalcMe so it will do the computations for us, and then we set the result as the correct answer.

Select the question type

First, we need to select which type of question we will use. Just as in the examples above, the best possible options are Short answer because we expect the student to answer with just the result.

Moodle panel where we select the WirisQuizzes question type; Short answer - science in this case

Create random numbers

Before writing the statement, let us write the algorithm of the question. Open WirisQuizzes Studio by clicking quizzes_studio_4.png.

WirisQuizzes Studio main page

Go to the Random variables section. As you can see, CalcMe is now the default option to generate the question's algorithm and, unless you are working with a previously created question, you can't use Wiris CAS (the old calculator) anymore. What you see is CalcMe

Empty CalcMe session as you see the calculator when you open it for the first time

Important

For getting started with CalcMe, see its very very basic guide.

The random command allows us to retrieve a random number in a given interval. We need four random numbers: two numerators and two denominators; that we will call a, b, c, d (the name of the variables is essential, as we will see later on). Let us write the algorithm using the code editor (Ctrl + Shift + B).

CalcMe algorithm to generate the four random values

We have four random numbers between 1 and 9 (both included). We will also compute the sum of the fractions they define and store the result in a variable.

CalcMe algorithm to generate the four random values and the question's correct answer

That is all we have to do regarding the algorithm. Click the arrow on the upper left corner to go back to WirisQuizzes Studio

Arrow click to go back to WirisQuizzes Studio from CalcMe

Tip

If you used CalcMe before, you might have noticed some differences with previous versions. You can see further details about the new procedure to define variables here.

Write the correct answer

The answer is not a number; it is a variable called sol. In order to write a variable anywhere outside CalcMe , we must precede the name of the variable with the pound sign #. Therefore, we will write #sol in the correct answer field.

WirisQuizzes Studio main page with the question's correct answer variable

Note

Recall the student will see the same math editor as we do where we write the correct answer or in the Test the question section, so it is essential for either the Math editor embedded or Math editor in popup option to be selected.

Make sure it all works

Finally, go to the Test the question section and try some possible answers: check everything works as expected. Although the provided correct answer provided is simplified, if no additional property is selected, any answer mathematically equal to the correct one will be accurate.

sum_of_two_fractions_random_preview.png

Note

Now we have another button next to the correct answer in the Test this question section: prev_ex1.6.png. This button appears because our algorithm deals with randomness. Every time we click this button, the algorithm will be re-executed, and the random numbers will change.

Save the changes and assign full grade

Once you have finished testing the question, go back to the home page and click wiris_quizzes_save.png to save changes and WirisQuizzes Studio window closes.

Write the statement

Now we proceed to write the statement of the problem. Recall that our numerators and denominators were stored in variables called a, b, c, d. Remember, we have to write the name of the variables preceded by the pound sign #. Fractions can be written with MathType

Every time we preview the question, the numbers in the statement will be different.

Area of a rectangle

One of the most common questions in the first years of high school is to ask the area of a rectangle, which is simply the result of multiplying the length of its base by its height. This type of question is also helpful to check whether the students have understood how to work with units.

This example will let us introduce units of measure in our questions.

Select the question type

Let's select which type of question we will use. As above, the best of the possible options here is Short answer because we expect the student to answer with just the result.

Moodle panel where we select the WirisQuizzes question type; Short answer - science in this case

Write the statement

Second, let us write the statement of the problem. We will ask the students, for instance, to compute the area of a rectangle with base 4cm and height 5cm.

Statement of the question asking for the area of a rectangle with the values introduced with MathType

Write the correct answer

WirisQuizzes can automatically grade the student's answer once we provide the correct answer. It will not only compare if the answer is the same, but it will also check if the answers are mathematically equal. In our example, it will grade as correct both 4·5cm2 and 20cm220\;\text{cm}^2. We will provide, for instance, 20cm220\;\text{cm}^2 as the correct answer.

WirisQuizzes Studio with the correct answer of the question

Enable units of measure

Go to the Input options section and check the units of measure and prefixes you are interested in under Input syntax. In this case, you have to select, at least, m (for the unit meters) and c (for the prefix centi).

Selecting the corresponding units of measure and prefixes to enable them within the Input options section

Note that now both c (centi) and m (meters) are coloured blue because they are selected as explained above to be understood as a metric prefix and a unit, respectively.

Preview the question and save the changes

It is always a good practice to test how they behave using the Test this question section, even with simple questions. We can check that all the correct answers the student may provide are indeed correct. Moreover, we can see that if the students forget to write the units, they will get zero points.

Once you have finished testing the question, go back to the home page and click wiris_quizzes_save.png to save changes and WirisQuizzes Studio window closes.

Finally, we must assign the full grade to the correct answer and save the question by clicking Save and continue editing. This way, we will save the question, but we will be left on the same page.

Animation showing how to assign the full grade to the correct answer and save the changes

Tip

Not assigning the full grade to a response is useful when penalising some answers. For instance, in this case, we could create a second answer without the units and assign 50% of the grade to it. There's another example below that illustrates this.

Area of a random rectangle

Consider the question in the previous example. Imagine we want to include that question on a quiz. All the students will see the same question with the exact dimensions! Wouldn't it be nice to have a different question for each student? This is possible with a simple command in WirisQuizzes

The idea is to generate two random numbers for base and height, so every time a student opens the question, there will be different numbers in the statement.

And what about the correct answer? Do we need to assign a correct answer to each possible case? Of course not! We will treat measures as variables, evaluate their product inside CalcMe so it will do the computations for us, and then we set as correct answer the result.

Select the question type

First, we need to select which type of question we will use. Among all the possible options, the best one here is Short answer because we expect the student to answer with just the result.

Create random numbers

Second, we will write the algorithm. Go to the Random variables section. What you see is CalcMe

Empty CalcMe session as you see the calculator when you open it for the first time

Important

For getting started with CalcMe, see its very very basic guide.

The random command allows us to retrieve a random number in a given interval. We need two random numbers: one for the rectangle's base and one for the height. We will name these variables b and h, respectively. The variables' names are essential, as we've seen in previous examples. We will also compute the product of the quantities and store the result in a variable. Let's write the code.

Important

Units need to be introduced via the symbols available under the Units of measure tab. See the very very basic guide of CalcMe for more information.

CalcMe algorithm generating the random variables for the question

Now we have two random units whose magnitude is between 1 and 9, inclusive. We will also compute the product of the quantities and store the result in a variable.

Penalization for forgetting the units

In the previous examples, we have mentioned it is possible to penalize students' grades if they forget to write the units. Let's create a random question as before but

  • Students will get 100% of the score if they write the area of the rectangle with the correct units.

  • Students will get 50% of the score if they write the area of the rectangle without units.

Convert grams to number of moles and particles

In chemistry, one may be interested in converting from grams of a substance to the number of moles and particles. In this example, we will create a question that, given the mass of a substance in grams, the student should compute how many moles and molecules it contains, correct to 2 correct decimal places.

Select the question type

First, we need to select which type of question we will use. There are several possible options , and once again, the best one for this example is Short answer because we expect the student to answer with just the result.

In this example, we are asking two questions: the number of moles and the number of particles. How do we do this?

Go to the Correct answer section and write both subquestions in different lines.

WirisQuizzes Studio main page with the correct answers of the question

Then, you need to select Grade answer boxes separately in the Input options section not to evaluate the entire content as a single value. We have two choices regarding the grading: either the whole question is correct if all the subquestions are correct, or the whole mark is the sum of the distributed grades for each subquestion. Here, for instance, we distribute the grade equally: 50% for the first one and 50% for the second one.

Compound answer option selection to enable the two different subquestions

Tip

Note we have selected a Compound answer. This option allows us to ask for multiple solutions in a single question, which is very useful when both subquestions are related. Everything on the left-hand side of the equal sign will be part of the statement, and on the right-hand side, a box will appear so that the students can answer them accordingly.

Preview the question

It is always a good practice to test how they behave using the Test this question section, even with simple questions. We can make sure the whole grade combines each subquestion's grade.

Change the tolerance

Until now, we were using the default tolerance setting: 0.1 per cent error. In this question, we want to count as correct an answer if it is accurate to two right decimal places.

Go to the Validation options section and modify the tolerance field, which becomes two decimal places, as in the animation below.

Match the plot

We will ask the student to match a function with its graph in the following example. Thus, we will incorporate a plot in the statement. Let us see how it is done.

Select the question type

First, we will select which type of question we will use. Until now, we have been using Short answer, but now we will choose Multiple choice since we want the student to select the correct option among all the possibilities that we will give.

Construct the plot

For instance, we will show the plot of x2x^2 , and then students will have to choose from some possibilities. Let us then create the plot of x2x^2. Open WirisQuizzes Studio by clicking quizzes_studio_4.png, then go to Define random variables and functions section and open CalcMe

We directly write x2x^2 and click on Plot. Pay attention that the graph appears in the first plotter , plotter1.

Create the possible answers

On the Answers section, create three different choices x2x^2, x3 and 2x+1 and assign 100% of the grade to the correct one.

It is possible to specify some feedback for each choice. Feedback is what appears once the student has answered the question. We can write Congratulations! for those who answer correctly, and Your answer is not correct; that is a parabola! for those who fail.

Different choices to provide the student with their corresponding grades and feedback

Write the statement

Finally, let us write the statement of the problem. Recall that the function graph was plotted in the first plotter , plotter1, to be our variable. Then we need to precede by # the variable's name, in this case, plotter1. The statement will look like

Statement of the question

Note

From this moment on, it's possible to customize the size of your plotter graphs in the question's statement. Make your plotter more visible by using the following commands:

  • #yourplottername_desiredsize

  • #yourplottername_desiredwidth_desiredheight

For example, if we want to display our plotter with a custom size of 800px per 600px, we need to use the syntax #plotter1_800_600 on the question statement.

Statement of the question modifying the plotter size

Label of the options and shuffling

We have almost finished, but small details are missing. We should specify that only one answer is correct, whether we want to shuffle the choices or not (so that the order in which the choices appear is different for each student), and which label is used for each choice.

Roots of a polynomial

In the following example, we will ask the student to write a polynomial expression given its roots. Moreover, we will plot the polynomial the student gives to compare their solution with the correct one.

Select the question type

We'll select which type of question we will use. Most of the examples on this page use Short answer. Since we expect the student to answer this question with just the result, Short answer is the best of all the possible options for this one as well.

Compute the correct answers

Open WirisQuizzes Studio by clicking quizzes_studio_4.png, then go to the Correct answer section and write the correct answer.

Note

Since we are checking if the student's answer and the correct answer are mathematically equal, the order in which we write the correct answer is unnecessary.

Store the student answer

Next, go to the Random variables section and open CalcMe.

Empty CalcMe session as you see the calculator when you open it for the first time

The student's answer is stored in a parameter called answer. Therefore, to work with it, we have to define this parameter. As we want to compare the correct answer and the student's answer, we have to plot both of them. The code to do so looks like this:

CalcMe algorithm of the question with the corresponding feedback

The default value for the parameter answer is zero; that is why the red plot is always zero. Don't worry; it will look more friendly with the response from the student.

It is always a good practice to test how they behave using the Test this question section, even with simple questions. Once again, the order is not essential. The plot will appear in the preview of the whole question.

If the student answers with the polynomial in expanded form, it will be graded as correct since it will be mathematically equal to the right answer we have provided.

Note

Go to the General feedback field. Everything we write here will be shown to the students once they answer. Therefore, we can write here all the steps they have to carry out when solving a problem or compare their answer with the correct one, as we will do here.

Recall that the correct answer's graph is blue and the one stored in the parameter answer (the student's answer) is red. The plot is stored in a variable called plotter1 so that we will include it on the feedback preceded with the pound symbol #.
