Dimensions of access

Main concepts

  • Five dimensions of access

Note: “Access” is likely to be a threshold concept in population health.

💡 A threshold concept is a concept so important that it is must be understood before moving on. Rather than new information, a threshold concept is described as a gateway, which once passed through unlocks a way of seeing information that was previously not accessible. When we understand threshold concepts, we often call these the “lightbulb” or “aha” moments.

Significant research shows that misunderstanding a threshold concept has significant (potentially life-long) ramifications for future learning. Threshold concepts are rare, with entire fields of study like biology containing less than a dozen. Some threshold concepts are so difficult to identify that we still haven’t mapped them all out for some fields!
