Now that you've started to build an advanced assessment, you may want to add a Cloze Chemistry with Image question.

In the Cloze Chemistry with Image question, students can input complex chemistry formulas on an image, using response boxes.

Example:

Build the Question

If you are creating a new item, select the + Create button on the assessment builder, title the item, then select the Add New plus sign to add a question.

If you are adding to an existing item, simply select the Add New plus sign (as shown above) to add a question to the item.

Next, select the Chemistry category from the options on the left, then select Cloze Chemistry with Image.

Compose Question and Upload Image

Compose question: Type question prompt into this field.

You have many formatting options from the Rich Text toolbar, including changing the font size, adding tables, using math symbols, adding multimedia, and more! Click here for more information on the different functions of the Rich Text toolbar.

Upload the image by selecting the Edit button.

Adjust or Add Response Boxes

There will be one response box already added to the image by default.

Adding Response Boxes:

❗ Note - the image will "refresh" with each change you make; this is not an error!

Select the + ADD button to add a response box.
Select the X in the bottom-right corner of the response box to remove it.
To reposition, you can click and drag each response box to its desired location.

Resizing and Adding Labels

How do you know where to make the changes? See images below:

Resizing:

The default width is 60px. Use that as your point of reference. Add numerical values into the Width (px) and Height (px) sections to adjust the size of the response boxes.

Note - the image will "refresh" with each change you make; this is not an error!

Adding Labels

In the formula template (or template) section, add any labels or symbols that you want to appear with the response box. Remember, adjusting anything in the Response Container (global) section only applies to response boxes you add from that point forward, so if you need to add a label to the response box already on the image, use the template under the Response Containers (individual) section. See the clip below.
Please keep in mind that anything you add in this template will also need to be included in your correct answer. If you do not include the label/symbol when you set the correct answer, student responses will not be scored correctly.

Set Correct Answer and Scoring

Step 1: Point Value and Correct Answer

Determine how many points the question will be worth.
Indicate the correct answer in the Value section. Remember, if you included a label in the template, that label must also be included here.

Is there more than one correct answer?

Add alternate answers by selecting the blue + button shown here.

Do you need to accept a range of answers (tolerance)?

Use the +/- symbol in your answer. For an example of any number between 3 and 3.5, you will want to set the answer as such: 3.25 +/- 0.25, which essentially adds a tolerance of 0.25 on the low and high end of the value.

Step 2: Scoring Method

Choose from the following scoring methods:

equivLiteral, equivSymbolic, or equivValue

💡 Tip from the Otus Team: equivSymbolic is the most commonly used method, and will provide the most flexibility when scoring. See details below.

equivLiteral

Only accepts a response that is mathematically equivalent to the correct answer AND is given in the same form.

If the correct answer is 8 + x, only 8 + x will be accepted (not x + 8, 8 + 1x, or any other variation)

equivSymbolic

Will accept a response that is mathematically equivalent to the correct answer, even if they are in different forms. This is the method you should use if your answer involves variables or if your answer involves multiple parts that can be in any order.

If the correct answer is 8 + x, 8 + x, x + 8 and 8+1x will all be accepted.

equivValue

Very similar to equivSymbolic, but equivValue will compare numerical values thatmay be represented in different ways, such as units of measurement. It is most often not necessary to use equivValue (when in doubt, use equivSymbolic).

If the correct answer is 14ft, a student response such as 168in will be correct.

Step 3: Repeat for additional response boxes

Each additional response box will have its own scoring section; select each section to expand and set the scoring.

Step 4: Scoring Type.

The scoring type refers to how the question is to be graded as a whole. This is especially important if you have more than one response box in the question.

Exact Match

The entire question must be answered correctly to receive the point(s).

Partial Match per Response

Each response is scored independently, and each is worth the number of points indicated in the point(s) field.

In the example above, choosing this option will make this question worth 2 points; the student will earn 1 point for the correct answer in each response box, for a total of 2 points.

Partial Match

Similar to partial match per response, each response is scored independently, but the point value indicated in the point(s) field is evenly split among the responses.

In the example above example, since the point value is set to 1, and there are 2 responses, each response is worth 0.5 points (1 point divided by 2 answers); the student will earn 0.5 points for the correct answer in each response box, for a total of 1 point.

Student Preview

It's highly recommended to Preview the question as you are building it in the item. This displays the question as the students will see it and also verifies that the answers and scoring work as expected.

Step 1: Select the Preview button to go into Preview mode.
Step 2: Answer the question with the correct answers, including alternates.
- Selecting Show Answers will present the correct answers.
Step 3: Verify that the auto-score correctly calculates the point value.

More Options

There are other layout, formatting, and scoring options available.

Other Scoring Options:

Unscored/Practice usage: removes all scoring from the item.
Check answer button & Check answer attempts: find more information here!
Penalty points: use this option if you want students to lose points for giving incorrect answers.
Minimum score if attempted: student will receive points as long as the question has been attempted (if the question is left blank or is unanswered, the student will not earn those points).

Layout Options:

The most commonly used layout option here is the font size.

Change the font size: In the Font size dropdown menu, you can change the font size of all components of the question to small, normal, large, extra large, or huge.

Keypad Options:

There are several different keypads to choose from, as well as placements of the keypad. For more information, check out this article.
