Intervention Domain - Overview

Key Entities

This domain contains:

• The InterventionPrescription entity, which describes an activity intended to address a specific problem or diagnosis. It identifies the kinds of students targeted and how the intervention should be delivered.
• The Intervention entity, which is a specific implementation of an instructional approach, outlined in an InterventionPrescription entity.
• A StudentInterventionAttendanceEvent entity which captures attendance and participation for interventions.
• A StudentInterventionAssociation entity, which links students to interventions in which they participate.
• Data about a formal InterventionStudy entity for an InterventionPrescription entity may also be associated with an InterventionPrescription.

Key Concepts

The key concepts include the following:

• The InterventionPrescription entity is a course of action designated by appropriate personnel to remedy an academic or behavioral issue, while the Intervention entity is the resulting action requiring participation by the student. 

• The StudentInterventionAssociation entity captures data related to the student's participation in the entity, such as the effectiveness or dosage.
• Interventions can be tied to a Cohort entity, but only through the StudentInterventionAssociation entity.
• Interventions may be one-time actions or recurring actions over time. The StudentInterventionAttendanceEvent can be used to capture the record of a student's participation in an intervention.
• Dosage in the model
  • Prescribed time for an intervention is stored in Dosage elements. These may be a range of recommended time in minutes (e.g., MinDosage and MaxDosage in the Intervention and InterventionPrescription entities) or prescribed time in minutes for a particular student (e.g., Dosage in the StudentInterventionAssociation entity).
  • Actual time spent in an intervention is captured via the InterventionDuration element on the StudentInterventionAttendanceEvent entity.
• EducationContent metadata may be linked to InterventionPrescription entities and/or Intervention entities. The EducationContent entity includes descriptive information about the content, and was derived from the metadata model for the Learning Resource Metadata Initiative (LRMI).
