Downloading Data

You can download the data from your students’ work using the xake data command.

To download the data, run xake data download. This will save your data as a log.sz file.

Viewing and Exporting Data

To see your data, you can run either xake data csv to access a csv version of the data, or xake data json to access a json version. The json version contains much more material.

To save the output as a file, use e.g. xake data json > myData.json.

Analyzing Data

Analyzing these data can be difficult because there is so much. If you use R for analysis, the jsonlite package will import the xake data export into a data frame.

Before loading the json file, open it in a text editor. You will see ”This is xake, Version 0.9.2” at the beginning with a line break. Delete these so a square bracket is the first line. On the last line, there will be a last comma that needs to be deleted before the final square bracket. Delete this and save the file.

If your data has been saved as myData.json, you can use myData <- fromJSON("myData.json", flatten=TRUE) to save the data as a dataframe.

Variables

The most relevant variables for analysis are:

• actor: identifies the person until the session has ended. A person may have multiple actor codes depending on whether they have logged it or not, or used different computer, etc.
• stored: the time when the entry occurred. Timestamp is based on the user’s computer, and maybe or off by hours depending on how their computer is set up. stored is a better choice for the time
• verb.display.en-US: the verb for what was happening at that record
  • experienced: a page loaded
  • answered: a question was answered
  • completed: something was completed (not sure what qualifies here)
  • played: a video was played
  • watched: a video was watched from some time to another time
  • skipped: a video was skipped from one time to another time (after being paused)
• object.definition.name.en-US: the name of the page loaded
• result.response: whatever was entered into an answer box
• result.success: if the question is graded, this is TRUE if that answer was correct and FALSE if the answer was incorrect.
