SNORDIAN's H5PxAPIkatchu

This Wordpress plugin is a simple solution to catch 'em all, those xAPI statements that have been sent by H5P content types. It allows you to store (the most relevant) xAPI properties in the database of WordPress. It also allows you to view, filter and export these data as a CSV file for further processing.

Please cmp. Gotta catch ’em all! and Collecting and analyzing data with H5P — and opening up education maybe for the ideas behind the plugin.

This plugin is NOT intended to work as a replacement for a decent Learning Record Store. It will work well for smaller platforms, but if you are expecting to track many xAPI statements, you will probably run into trouble with displaying all the data at some point.

This plugin is NOT intended to forward xAPI statements sent by H5P to a Learning Record Store. Please use WP-H5P-xAPI if you need that functionality.

This plugin is NOT intended to replace the H5P plugin's reporting or provide functionality for analysis, etc. There is no point in recreating what is already available in Learning Record Stores or what you can do yourself with a spreadsheet software, scikit-learn, etc.

If you need more, you should give Learning Locker a shot. It's open, free and shiny.

PLEASE NOTE: H5P IS A REGISTERED TRADEMARK OF JOUBEL. THIS PLUGIN WAS NEITHER CREATED BY JOUBEL NOR IS IT ENDORSED BY THEM.

Features

• Store important values of xAPI statements emitted from H5P content types in your database.
• View and export the data for further analysis.
• Optionally limit capturing to particular H5P content types only.
• Optionally store the complete xAPI statements as a string - know what you're doing ...

Install/Usage

Install H5PxAPIkatchu from the Wordpress Plugin directory or via your Wordpress instance and activate it. Done.

The most important parts of the xAPI statements that are emitted by H5P content types on your system should now be stored in your database. You can view and download them via the new WordPress menu item.

Screenshots

You can change some options to your particular needs.

You cannot only view the stored data, but also download them as an CSV file.

Example filters

Not saving certain verbs

In certain situations, one may only be interested in xAPI statements with particular verbs. The plugin does not provide a list to define what should be listend to and what should not (as in LRS logic one would rather do this by filtering the data later on), but one can do this by adding a filter to one's WordPress environment.

Please note: Despite not trying to be a gradebook replacement, people seem to be using H5PxAPIkatchu as such. They are only interested in "scores and answers". However, the whole point of xAPI is to be able to gain deeper knowledge about what the user is experiencing. If one is only interested in storing scores and answers, one should rather amend the original H5P plugin (or create a separate plugin for this job), so only the relevant values are stored which then then can be displayed easily using https://github.com/h5p/h5p-php-report.

Nevertheless, if you're interested in "scores and answers" only and want to do this using H5PxAPIkatchu, filtering for verbs may not be the proper approach - one would rather filter for statements that contains a results property, because there's no fixed list of verbs that could pop up with xAPI, and content types could as well use other verbs than completed or answered and yet the statements could contain "scores and answers".

add_filter( 'h5pxapikatchu_insert_data_verb', 'filter_h5pxapikatchu_insert_data_verb', 10 );
function filter_h5pxapikatchu_insert_data_verb( $verb ) {
  if ( is_array( $verb ) && in_array( $verb['display'], array( 'interacted', 'attempted' ) ) ) {
    wp_die();
  }

  return $verb;
}
