* - **Display Name**
- Specifies the name of the problem.
* - **custom_parameters** [string]
- With the "+ Add" button, multiple custom parameters can be
added. Basically, each individual external LTI provider can have a separate
format custom parameters. For example::
key=value
* - `Setting`
- Description
* - `Display Name`
- Specifies the name of the problem. This name appears above the problem and in
the course ribbon at the top of the page in the courseware.
* - `custom_parameters` [string]
- Enables you to add one or more custom parameters. Basically,
each individual external LTI provider can have a separate format custom
parameters. For example:
key=value
To add a custom parameter, click **Add**.
* - `graded`
- Indicates whether the grade for the problem counts towards student's total grade. By
default, this value is set to **False**.
* - `has_score`
- Specifies whether the problem has a numerical score. By default, this value
is set to **False**. (**SP: Is this accurate?**)
* - `launch_url`
- Lists the URL that Studio sends to the external LTI provider so that the provider
can send back students' grades. This setting is only used if **graded** is set to
**True**. (**SP: Is this accurate? How does the user find the launch URL?**)
* - `lti_id`
- Specifies the LTI ID for the external LTI provider. This value must be the same
LTI ID that you entered on the **Advanced Settings** page.
* - `open_in_a_new_page`
- Indicates whether the problem opens in a new page. If you set this value to **True**,
the student clicks a link that opens the LTI content in a new window. If you set
this value to **False**, the LTI content opens in an IFrame in the current page.
* - `weight` [float]
- If the problem will be graded by an external LTI provider,
the raw grade will be in the range [0.0, 1.0]. In order to change this range,
set the `weight`. The grade that will be stored is calculated by the formula:
stored_grade = raw_grade * weight
.. note:: **SP: I'm not clear on what a custom parameter would be used for. Based on
the Studio UI, I'm guessing that one example would be the location of an

Enables you to add one or more custom parameters. For
example, a custom parameter may include the location (**SP: Would it be

Every custom parameter has a key and a value. You must add the key and
value in the following format.

LTI IDs that you entered on the **Advanced Settings** page.
* - **open_in_a_new_page** [boolean]
- Indicates whether the problem opens in a new page. If you set this value to True,
the student clicks a link that opens the LTI content in a new window. If you set
this value to False, the LTI content opens in an IFrame in the current page.
* - **weight** [float]
- If the problem will be graded by an external LTI provider,
the raw grade will be in the range [0.0, 1.0]. In order to change this range,
set the `weight`. The grade that will be stored is calculated by the formula:
stored_grade = raw_grade * weight
(**SP: Raw grade means points earned?**)
.. note:: **SP: Would it be correct to say the following?**
Specifies the number of points possible for the problem. By default, if
an external LTI provider grades the problem, the problem is worth 1 point,
and a student's score can be 0 or 1.
