Response Map

The response map is an LTI tool that allows students to respond to a question or give feedback and have the responses show up on a world map based on the location that they enter in. All the response are also processed and turned into a word cloud at the bottom of the map. Students can also upload an image along with their response.

Requirements

You will need have an Apache HTTP server which is configured to serve PHP files and have a MySQL database configured to store student details and responses.

Dependencies

• PHP 5.3+ (tested with 5.4 and 5.5)
• PHP extensions: mysqli, gd, imagick

Installation

1. Enable a Google Geocoding API. Refer to Google's instructions for details.
2. Set the configuration variables required (MySQL credentials, Google Geocoding API key, LTI key and secret) in one of the two methods below:
   • Set them as environment variables. Refer to configuration.php for variable names.
   • Save a copy of config.example.php as config.php and edit the configuration variables.
3. Create a database with the name set in Step 2 and import response_map.sql to create the necessary tables.

Integrating with edX

1. Enable LTI component for your course.
2. Also under Advanced Settings, the LTI Passports array must contain the LTI key and secret pair that is used by the tool (set in Step 2). You must add it to the array in the following format: "passport_id:key:secret". The id is later used when configuring the LTI component to obtain the key and secret.
3. Next, create the LTI component within a course unit (under Add New Component > Advanced > LTI) and click on "Edit". Make sure to enter in the the LTI ID that you have previously set in LTI Passport. Specify the url to the tool (make sure you have a closing slash) and turn off opening in a new page for a seamless look. If you would like to give a student a partipation mark for responding to the response-map, then set the "Scored" attribute to true.

Notes

• If your edX instance is using http instead of https. Add HTTPS: "off" to lms.envs.json and restart the server to get the grading functionality to work. The reason is even though edX may be on http the outcome url passed to Response Map uses https.
• Currently, there is a limitation of only having one map per subsection.

Integrating with other Platforms

Please refer to the your Platform's LTI integration instructions.
