What kind of activity was the student engaged in – was it a classroom, a course, a mobile application, a question, an evaluation, an e-book, a simulation or even a video? If you want to make useful queries and analysis of your xAPI data model has a “cube” to store user reactions to interactions, learning activities, and their collective results. If you dig a little deeper and look at all that xAPI has to offer, you will quickly realize that there is still plenty of room to improve your learning analysis beyond what is normally only recorded in actors, verbs, and parts of the thesis objects. Probably one of the most important things you can do with your xAPI statements is to make sure that there is absolutely no chance of accidentally creating the same activity ID or using it for different activities, or creating a new unique ID for each session. I have often seen xAPI statements that have the same meaning for grouping and parent activity, which can lead to problems when performing meaningful analysis. We check the spelling of our text when we write it so that people can read it. So why not check the quality of the survey data, which should be necessary for further consultation? It is important to use correct identifiers for verbs and activities in statements.
